BackgroundWeight loss response to sleeve gastrectomy (SG) is variable and predicting the effectiveness of surgery is challenging and elusive. The aim of our study was to assess and quantify the association between eating control and weight loss outcomes and identify the control of eating (CoE) attributes during the early postoperative period that might predict good vs. poor response to SG at one year.MethodsA prospective longitudinal cohort study using the Control of Eating Questionnaire (CoEQ) was designed as a series before and at 3-, 6-, and 12-months post-SG. Primary outcomes were changes in CoE attributes and percent of total weight loss (%TWL) 12-months post-surgery. Subjects were categorized based on %TWL as good (GR, ≥25 %) or poor responders (PR,

Bariatric surgery has emerged as an effective therapeutic approach for combating obesity. As the most commonly performed bariatric surgery, laparoscopic sleeve gastrectomy (LSG) has a long-term and effective outcome in weight reduction. However, studies have reported an increased incidence of gastroesophageal reflux disease (GERD) among patients after LSG. For those who fail to respond to conventional oral acid-suppressing medication, surgical intervention comes into consideration. The most commonly performed revisional surgery for sleeve gastrectomy is the Roux-en-Y gastric bypass, which can effectively alleviate the symptoms of reflux in patients and also continues to promote weight loss in patients who have not achieved satisfactory results or have experienced weight regain. In addition to this established procedure, innovative techniques such as laparoscopic magnetic sphincter augmentation (MSA) are being explored. MSA is less invasive, has good reflux treatment outcomes, and its safety and efficacy are supported by the literature, making it a promising tool for the future treatment of gastroesophageal reflux. This article also explores the role of endoscopic interventions for GERD treatment of post-sleeve gastrectomy patients. Although these methods have shown some therapeutic effect, their efficacy still requires further study due to a lack of support from more clinical data. For patients with preoperative hiatal hernia or gastroesophageal reflux symptoms, some experts now consider performing LSG combined with hiatal hernia repair or fundoplication to alleviate or prevent postoperative reflux symptoms. Both of these surgical approaches have demonstrated favorable outcomes; however, the addition of fundoplication requires further investigation regarding its long-term effects and potential postoperative complications. This article gathers and examines the current laparoscopic and endoscopic treatments for refractory gastroesophageal reflux following LSG, as well as the concurrent treatment of LSG in patients with preoperative gastroesophageal reflux or hiatal hernia.

Background: The obesity epidemic has led to an increased number of adolescents requiring metabolic and bariatric surgery (MBS), but there is paucity of data on the impact of implementing all aspects of Enhanced Recovery After Surgery (ERAS) protocols to improve outcomes in this population. Methods: We implemented a comprehensive ERAS pathway for adolescents undergoing laparoscopic sleeve gastrectomy (LSG). Key elements included pre-operative fasting with carbohydrate loading in the morning of surgery, comprehensive anti-emetic and analgesic regimens including intra-operative lidocaine infusion (initiated before formal ERAS launch), regional anesthesia, and early goal-directed ambulation. We tracked opioid utilization, rescue anti-emetic use, time to oral intake, and hospital length of stay (HLOS) as outcome measures, and post-operative pain and returns to the system as balancing measures. Results: Eighty-six patients (52 patients pre-ERAS and 34 patients post-ERAS) underwent LSG with no differences in demographics. The post-ERAS group had earlier time to oral intake (3.0 vs. 5.5 h, p = 0.003), used less rescue anti-emetics, (8.0 vs. 16.0 mg, p < 0.001), and had shorter HLOS (33 vs. 54 h, p < 0.001) but no difference in opioid use (0.370 vs. 0.435 MME/kg, p = 0.17), post-operative pain scores or return to the system. Conclusions: Our novel use of bariatric-specific ERAS protocol with intra-operative lidocaine infusion accelerates the time to goal-directed oral intake and decreases HLOS without increasing the rate of returns to the system. This study highlights the feasibility and effectiveness of adapting adult ERAS protocols to the pediatric MBS population. Level of evidence: Level III. [ABSTRACT FROM AUTHOR]

Background: Iron is an essential element for thyroid function. However, no study focuses on the association between iron and thyroid in individuals with obesity. Our research aimed to investigate the iron status in relation to baseline thyroid hormone levels and after laparoscopic sleeve gastrectomy (LSG). Methods: A total of 216 subjects with obesity were enrolled and divided into low and high iron groups depending on the median value. The association between iron and thyroid hormone was analyzed and compared before and after LSG at the 6-month follow-up in patients who underwent LSG. Results: 1) In all, Total Triiodothyronine (TT3) was significantly higher in high iron than low iron group (P = 0.008). TT3 and thyroid stimulating hormone (TSH) were significantly higher in high iron than low iron group (1.92 ± 0.61 vs. 1.69 ± 0.28 nmol/l, P = 0.029; 2.93 ± 1.66 vs. 1.88 ± 1.03 mU/l, P = 0.002) in females while not in males (all P > 0.05). 2) Iron was significantly positively associated with free triiodothyronine (FT3), free thyroxine (FT4), TT3 and TSH (all P < 0.05). Adjusted for body mass index (BMI), total cholesterol (TCH), high-density lipoprotein cholesterol (HDL-C), fasting insulin (FINS) and homeostatic model assessment of insulin resistance (HOMA-IR), FT3, FT4 and TSH were still significantly associated with iron (all P < 0.05). 3). Regression analysis showed that iron was significantly associated with FT4 (β = 0.338, P = 0.038). 3) LSG led to decreased FT3, FT3, TT3, total thyroxine (TT4) and TSH at 6 months follow-up (all P < 0.05). Changed FT4 was significantly associated with changed iron (r = 0.520, P = 0.009). Subjects with iron decreased had more significant decreased TT4 than subjects without iron decreased (P = 0.021). Conclusion: Serum iron overload is significantly associated with impaired thyroid function in subjects with obesity. LSG led to improved thyroid function which is associated with a change in iron.

Background Methods Results Conclusion Changes in gastrointestinal physiology following bariatric surgery may affect the pharmacokinetics of drugs. Data on the impact of bariatric surgery on drugs used for attention‐deficit/hyperactivity disorder (ADHD) are limited.In patients treated with ADHD medication and undergoing bariatric surgery, serial drug concentrations were measured for 24 h preoperatively and one, six and 12 months postoperatively. Primary outcome was change in area under the concentration‐time curve from 0 to 24 h (AUC0–24), with other pharmacokinetic variables as secondary outcomes.Eight patients treated with lisdexamphetamine (n = 4), dexamphetamine (n = 1), methylphenidate (n = 1) and atomoxetine (n = 2) were included. In total, 409 samples were analysed. Patients underwent sleeve gastrectomy (n = 5) and Roux‐en‐Y gastric bypass (n = 3). AUC0–24 and Cmax of dexamphetamine increased after surgery in those using the prodrug lisdexamphetamine. There was no clear‐cut reduction in tmax postoperatively. For ritalinic acid and atomoxetine, no changes in AUC0–24 were observed, but for atomoxetine, a higher Cmax and a shorter tmax were observed postoperatively.Bariatric surgery may increase the systemic exposure of dexamphetamine after intake of lisdexamphetamine. Patients using lisdexamphetamine should be followed with regard to adverse drug reactions after bariatric surgery, and, if available, therapeutic drug monitoring should be considered.

Introduction: This report aimed to analyze the outcomes of patients with obesity who were on a bariatric program during the SARS-Cov-2 pandemic outbreak and compare those who received surgery with the ones who were not operated on. Methods: This was a retrospective study between 2020 and 2021. Patients were divided into two groups: those who underwent surgery (O) and those who were not operated (NO). The evolution of the risk factors identified for severe COVID infection and death was studied (ASMBS criteria). For this study, a follow-up period of 12 months was initiated. Results: In the O group, 83 patients were included and 99 were in the NO group. In the O group, patients with body mass index (BMI) > 35 Kg/m2 before surgery resolved the condition in 73.5% (61) cases, and this was done in the first 30 days by 38 (45.7%). Type 2 diabetes mellitus remission was documented in 18 patients (85.7%) of the O group, and the mean time elapsed for remission was 102.2 days (P <.01). Hypertension remitted in 66.7% (20) of the patients in group O in 82.4 days (P <.01). The subgroup of patients with obesity and one high-risk associated condition (30.2%, 25) resolved both in 44% (11) cases and one in 48% (12) cases. In the group of patients with obesity and two high-risk associated conditions (15.6%, 13), 47% (6) patients resolved the three conditions, 38% (5) resolved two conditions, and 15% (2) resolved one condition. Among the NO group, no comorbidity resolutions were recorded (P <.01). Admission because of COVID infection was necessary for 7.1% of NO and 1.2% of O (P =.04). Conclusion: Bariatric metabolic surgery would not increase the risk of COVID infection or of suffering serious complications resulting from it. Patients undergoing bariatric metabolic surgery rapidly resolved high-risk comorbidities and had less need for hospitalization because of SARS-CoV-2 infection. [ABSTRACT FROM AUTHOR]

This study investigates the effects of bariatric surgery on non-alcoholic fatty liver disease (NAFLD) by examining the interplay between gut microbiota, epigenetics, and metabolic health. A cohort of 22 patients undergoing sleeve gastrectomy (SG) was analyzed for changes in gut microbial composition and DNA methylation profiles before and six months after surgery. Correlations between gut microbial abundance and clinical markers at baseline revealed that certain genera were associated with worse metabolic health and liver markers. Following SG, significant improvements were observed in the clinical, anthropometric, and biochemical parameters of the NAFLD patients. Although alpha-diversity indices (i.e., Chao1, Simpson, Shannon) did not show significant changes, beta-diversity analysis revealed a slight shift in microbial composition (PERMANOVA, p = 0.036). Differential abundance analysis identified significant changes in specific bacterial taxa, including an increase in beneficial Lactobacillus species such as Lactobacillus crispatus and Lactobacillus iners and a decrease in harmful taxa like Erysipelotrichia. Additionally, DNA methylation analysis revealed 609 significant differentially methylated CpG sites between the baseline values and six months post-surgery, with notable enrichment in genes related to the autophagy pathway, such as IRS4 and ATG4B. The results highlight the individualized responses to bariatric surgery and underscore the potential for personalized treatment strategies. In conclusion, integrating gut microbiota and epigenetic factors into NAFLD management could enhance treatment outcomes, suggesting that future research should explore microbiome-targeted therapies and long-term follow-ups on liver health post-surgery.

Bariatric surgery is increasingly performed to treat severe obesity. As a result of anatomical and physiological changes in the gastrointestinal tract, the pharmacokinetics (PK) of oral drugs can be altered, affecting their efficacy and safety. This includes the class of tyrosine kinase inhibitors (TKIs) which are used to treat chronic myeloid leukemia (CML). This case series describes the clinical course of four CML cases with a history of bariatric surgery. The patients used various TKIs (nilotinib, dasatinib, bosutinib, ponatinib, and imatinib) for which 15 drug levels were measured. The measured TKI concentrations were in part subtherapeutic, and highly variable when compared to mean levels measured in the general population. Multiple drug levels were measured in these patients, as the clinicians were aware of the possible impact of bariatric surgery. The drug levels were used as additional input for clinical decision-making. All four patients required TKI switches and/or dose modifications to achieve an effective and tolerable treatment. Eventually, adequate clinical and molecular remissions were achieved in all cases. In summary, TKI concentrations of patients undergoing bariatric surgery may be subtherapeutic. Moreover, there is substantial interindividual and intraindividual variation, which may be explained by the complex interference of bariatric surgery and associated weight loss. For clinical practice, therapeutic drug monitoring is advised in patients with a history of bariatric surgery in case of suboptimal response or loss of response. [ABSTRACT FROM AUTHOR]

Background: To evaluate 5-year effect of laparoscopic vertical sleeve gastrectomy (LVSG) versus laparoscopic roux-en-Y gastric bypass (LRYGB) on gastroesophageal reflux disease (GERD) solely based on randomized controlled trials (RCTs). Methods: A systematic review and meta-analysis of 5-year postoperative GERD data comparing LVSG and LRYGB in adults were undertaken. Electronic databases were searched from January 2015 to March 2024 for publications meeting inclusion criteria. The Hartung–Knapp–Sidik–Jonkman random effects model was applied to estimate pooled odds ratio where meta-analysis was possible. Bias and certainty of evidence were assessed using the Cochrane Risk of Bias Tool 2 and GRADE. Results: Five RCTs were analysed (LVSG n = 554, LRYGB n = 539). LVSG was associated with increased adverse GERD outcomes compared to LRYGB at 5 years. The odds for revisional surgery to treat GERD in LVSG patients were 11 times higher compared to LRYGB (OR 11.47, 95% CI 1.83 to 71.69; p = 0.02; I2 = 0% High level of certainty). Similarly pharmacological management for increasing GERD was significantly more frequent in LVSG patients compared to LRYGB (OR 3.89, 95% CI 2.31 to 6.55; p ≤ 0.01; I2 = 0% Moderate level of certainty). Overall, LVSG was associated with significantly more interventions (both medical and surgical) for either worsening GERD and/or development of de novo GERD compared to LRYGB (OR 5.98, 95% CI 3.48 to 10.29; p ≤ 0.01; I2 = 0%) Moderate level of certainty). Conclusions: The development and worsening of GERD symptoms are frequently associated with LVSG compared to LRYGB at 5 years postoperatively requiring either initiation or increase of pharmacotherapy or failing that revisional bariatric surgery. Appropriate patient/surgical selection is crucial to reduce these postoperative risks of GERD. [ABSTRACT FROM AUTHOR]

Background: Endometrial Cancer (EC) is strongly linked to obesity. Bariatric surgery is recognized as a long-term solution for weight loss in severely obese patients. This pilot study investigates the feasibility, intraoperative and 30-day morbidity outcomes of integrating gynecological surgical staging and bariatric robotic surgery in class II and III obese patients affected by early EC or Endometrial Intraepithelial Neoplasia (EIN). Methods: Patients aged over 18 years old with early EC or EIN and class II and III obesity (Body mass index (BMI) ≥ 35 kg/m2) who are surgical and anesthesiologic candidates. Standard robotic surgery for early EC staging performed alone (THBSO group) or in conjunction with sleeve gastrectomy (THBSO + SG group) for obesity management was proposed. Results: Of the 13 patients who met the inclusion criteria, 5 (38.46%) opted for combined surgery. The groups showed a significant difference in preoperative BMI (49.68 kg/m2 vs. 40.24 kg/m2p = 0.017 with and without SG), preoperative weight (143.92 kg vs. 105.62 kg p = 0.004 with and without SG), preoperative (p = 0.01) and postoperative (p = 0.005) aspartate transaminase (AST). The THBSO + SG group had higher anesthesia induction end-tidal carbon dioxide (ETCO2) (p = 0.05), final Partial pressure of carbon dioxide (PaCO2) (p = 0.044), anesthesia induction lactate (p = 0.001) and final lactate (p = 0.011) without a significant difference in final pH (p = 0.31). Operative time was longer in the THBSO + SG group (p < 0.001), but this did not result in longer ICU (p = 0.351), total hospital stays (p = 0.208), nor increased blood loss and transfusion. The simultaneous combined approach had an 80% success rate. At 6 months, the THBSO + SG group achieved significantly greater weight loss than the THBSO group (ΔBMI − 11.81 kg/m2 vs − 1.72 kg/m2, p = 0.003, with and without SG). Conclusion: Integrating robotic EC staging with SG in obese women with early EC increased the operative time without increasing intraoperative risks, early and 30 days post-surgery complication and offering a promising approach to simultaneously treating both conditions.

Introduction: Robotic-assisted metabolic and bariatric surgery (MBS) is gaining popularity. Revisional MBS is associated with higher perioperative morbidity compared to primary MBS. The optimal surgical approach to minimize complications in these complex cases is unclear. The goal of this study was to assess robot utilization in revisional MBS and compare laparoscopic and robotic revisional MBS outcomes in the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) database. Methods: A retrospective review of the MBSAQIP database was performed identifying revisional sleeve gastrectomy (SG) and Roux-en-Y gastric bypass (RYGB) cases from 2015 to 2022. Primary MBS, open/emergent cases, cases converted to another approach, and combined cases other than esophagogastroduodenoscopy were excluded. 30-Day outcomes for laparoscopic and robotic cases were compared using multivariate logistic regression adjusting for patient demographics, comorbidities, and operative variables. Results: 41,404 Cases (14,474 SG; 26,930 RYGB) were identified. From 2015 to 2022, the percentage of revisional SG and RYGB cases performed robotically increased from 6.1% and 7.3% to 24.2% and 32.0% respectively. Laparoscopic SG had similar rates of overall morbidity, leak, bleeding, readmission, reoperation, and length of stay compared to robotic. Laparoscopic RYGB had significantly higher rates of overall morbidity (6.2% vs. 4.8%, p < 0.001, AOR 0.80 [0.70–0.93]), blood transfusion (1.5% vs. 1.0%, p < 0.05, AOR 0.74 [0.55–0.99]), superficial incisional SSI (1.2% vs. 0.4%, p < 0.001, AOR 0.30 [0.19–0.47]), and longer length of stay (1.87 vs. 1.76 days, p < 0.001) compared to robotic. Laparoscopic operative times were significantly shorter than robotic (SG: 86.4 ± 45.8 vs. 113.5 ± 51.7 min; RYGB: 130.7 ± 64.7 vs. 165.5 ± 66.8 min, p < 0.001). Conclusion: Robot utilization in revisional bariatric surgery is increasing. Robotic surgery has lower postoperative morbidity and shorter length of stay in revisional RYGB when compared to laparoscopic. Robotic platforms may have the capacity to improve the delivery of care for patients undergoing revisional bariatric surgery. [ABSTRACT FROM AUTHOR]

Background: With the prevalence of obesity rising in the US, medical management is of increasing importance. Two popular options for the treatment of obesity are bariatric surgery (e.g. sleeve gastrectomy and Roux-en-Y gastric bypass) and the increasingly popular GLP-1 Receptor Agonists (GLP-1 s). This study examines the initial and long-term costs of GLP-1 s compared to bariatric surgery. Study design: We compared average 2023 national retail prices for GLP-1 s to surgical cost estimates from 2015 adjusted for inflation. We then plotted the cumulative medication cost over time against the flat cost of each surgery, thus calculating "break-even points" (when medication costs equal surgery costs). The findings revealed a crucial insight, for some GLP-1 s like Saxenda and Wegovy, the high cost of ongoing use surpasses the cost of RYGB in less than a year and sleeve gastrectomy within nine months. Even the most affordable option, Byetta, becomes costlier than surgery after around 1.5 years. Results: This highlights the importance of looking beyond the initial financial investment when considering cost-effectiveness. Additionally, while not directly assessed, this study acknowledges that GLP-1 s take time to reach full effectiveness, potentially delaying weight loss while accumulating costs. Concerns also exist about weight regain after discontinuing the medication. Conclusion: This study is limited by the real-world variation for individual treatment costs (e.g. insurance), a limited evaluation of long-term costs associated with either treatment modality and their co-morbidities, and the reality of patient preference providing subjective value to either modality. Overall, the study offers insights into the financial trade-offs between GLP-1 s and bariatric surgery. [ABSTRACT FROM AUTHOR]

Background: Food insecurity has been linked to higher rates of obesity. It has also been shown to diminish the effectiveness of weight loss strategies, including intensive lifestyle interventions. One essential component of food insecurity is having a geospatial disadvantage in access to healthy, affordable food, such as living within a food desert. This study aims to determine if food insecurity also impacts weight loss and nutritional outcomes in patients who underwent Roux-en-Y gastric bypass (RYGB) or sleeve gastrectomy (SG). Methods: Clinical outcomes of patients who underwent RYGB or SG at Cleveland Clinic or affiliate regional hospitals in the United States from 2010 to 2018 were collected. Modified Retail Food Environmental Index (mRFEI) data was collected from the Center for Disease Control and merged with patient census tract data, allowing the patient cohort to be divided into those living in areas identified as food secure (mRFEI > 10%), food swamps (mRFEI = 1–10%), or food deserts (mRFEI = 0). Postoperative weight change was evaluated with quadratic growth mixture models and stratified by surgery type. Results: A total of 5097 patients were included in this study cohort, including 3424 patients who underwent RYGB and 1673 who underwent SG. The median duration of follow-up was 2.3 years (IQR 0.89–3.6 years). Food security status was not associated with postoperative weight change (RYGB p = 0.73, SG p = 0.60), weight loss nadir (RYGB p = 0.60, SG p = 0.79), or weight regain (RYGB p = 0.93, SG p = 0.85). Deficiencies in nutritional markers at 1–2 years after surgery were also not significantly different between food security groups. Conclusion: Despite the established relationship between food insecurity and obesity, food insecurity does not negatively impact weight loss or nutritional outcomes following RYGB or SG, demonstrating metabolic surgery as a powerful and equitable tool for treating obesity. Level of Evidence: IV. [ABSTRACT FROM AUTHOR]

Type 2 diabetes mellitus (T2DM) is a chronic metabolic disorder exacerbated by obesity. Single Anastomosis Sleeve-Ileal Bypass (SASI) has emerged as a promising metabolic bariatric procedure that combines sleeve gastrectomy and ileal bypass, facilitating substantial weight loss and T2DM remission through restrictive and malabsorptive mechanisms. This study aims to evaluate the effects of SASI on T2DM remission, weight loss, and safety in one year follow-up. A retrospective cohort study analyzed 31 patients with obesity and T2DM who underwent SASI. Data collected included demographic characteristics, preoperative and postoperative BMI, HbA1c levels, and bariatric outcomes, including %TWL and T2DM changes. The mean age was 45 years, with a mean preoperative BMI of 40.7 kg/m². One year postoperatively, the mean %EWL was 85.6% and %TWL was 31.7%. T2DM remission was achieved in 24 (77.4%) patients, improvement in 4 (12.9%), and no change in 3 (9.7%). Hypertension improved in 21 (87.5%) patients, with 12 (50%) achieving remission. Significant reductions in BMI and HbA1c levels were observed (p < 0.001). Responders (R) and non-responders (NR) groups showed significant differences in postoperative BMI and %EWL (p = 0.007, p = 0.023). One patient experienced a Clavien-Dindo Grade III complication; no deaths occurred. SASI is an effective and safe procedure for treating T2DM, resulting in significant weight loss and metabolic improvements over a one-year follow-up. SASI seems to be a favorable option for T2DM management in metabolic bariatric surgery. [ABSTRACT FROM AUTHOR]

OBJECTIVE: Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG) are effective procedures to treat and manage type 2 diabetes (T2D). However, the underlying metabolic adaptations that mediate improvements in glucose homeostasis remain largely elusive. The purpose of this study was to identify metabolic signatures associated with biochemical resolution of T2D after medical therapy (MT) or bariatric surgery. RESEARCH DESIGN AND METHODS: Plasma samples from 90 patients (age 49.9 ± 7.6 years; 57.7% female) randomly assigned to MT (n = 30), RYGB (n = 30), or SG (n = 30) were retrospectively subjected to untargeted metabolomic analysis using ultra performance liquid chromatography with tandem mass spectrometry at baseline and 24 months of treatment. Phenotypic importance was determined by supervised machine learning. Associations between change in glucose homeostasis and circulating metabolites were assessed using a linear mixed effects model. RESULTS: The circulating metabolome was dramatically remodeled after SG and RYGB, with largely overlapping signatures after MT. Compared with MT, SG and RYGB profoundly enhanced the concentration of metabolites associated with lipid and amino acid signaling, while limiting xenobiotic metabolites, a function of decreased medication use. Random forest analysis revealed 2-hydroxydecanoate as having selective importance to RYGB and as the most distinguishing feature between MT, SG, and RYGB. To this end, change in 2-hydroxydecanoate correlated with reductions in fasting glucose after RYGB but not SG or MT. CONCLUSIONS: We identified a novel metabolomic fingerprint characterizing the longer-term adaptations to MT, RYGB, and SG. Notably, the metabolomic profiles of RYGB and SG procedures were distinct, indicating equivalent weight loss may be achieved by divergent effects on metabolism. [ABSTRACT FROM AUTHOR]

Background: The vertical banded gastroplasty (VBG) is a historic restrictive bariatric operation often requiring further surgery. In this investigation utilizing the 2021 Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) national dataset, we aim to better define the outcomes of VBG conversions.Methods: We queried the 2021 MBSAQIP dataset for patients who underwent a conversion from a VBG to Roux-en-Y gastric bypass (RYGB) or sleeve gastrectomy (SG). Demographics, comorbidities, laboratory values, and additional patient factors were examined. Rates of key consequential outcome measures 30-day readmission, reoperation, reintervention, mortality, and a composite endpoint (at least 1 of the 4) were further calculated.Results: We identified 231 patients who underwent conversion from VBG to SG (n = 23), RYGB (n = 208), or other anatomy (n = 6), of which 93% of patients were female, and 22% of non-white race. The median age was 56 years and body-mass index (BMI) was 43 kg/m2. The most common surgical indications included weight considerations (48%), reflux (25%), anatomic causes (eg, stricture, fistula, and ulcer; 10%), and dysphagia (6.5%). Thirty-day morbidity rates included reoperation (7.8%), readmission (9.1%), reintervention (4.3%), mortality (.4%), and the composite endpoint (15%). Upon bivariate analysis, we did not identify any specific risk factor for the 30-day composite endpoint.Discussion: One-stage VBG conversions to traditional bariatric anatomy are beset with higher 30-day morbidity relative to primary procedures. Additional MBSAQIP data will be required for aggregation, to better characterize the risk factors inherent in these operations. [ABSTRACT FROM AUTHOR]

Background: We aimed to compare the omentopexy and clipping reinforcement methods performed along the staple line during laparoscopic sleeve gastrectomy (LSG) in terms of the effectiveness on postoperative bleeding. Methods: In this prospective randomized controlled study, patients were divided into two groups: clips group (CG) and omentopexy group (OG). The groups were compared in terms of postoperative bleeding, duration of surgery, length of hospital stay, hospital readmissions in the postoperative first 30-days. Results: A total of 148 patients were included in the study. Postoperative bleeding was observed in 11 patients (14.9%) of CG and 2 patients (2.7%) of the OG, and the difference between the groups was found to be significant (p = 0.009). Similarly, the number of patients with bleeding that did not require intervention was 9 (12.2%) in CG and 2 (2.7%) in OG, and the difference between the groups was also significant (p = 0.028). The duration of surgery in the CG was 30 (27 to 36) minutes, whereas in the OG, it was 43 (39 to 45) minutes, with a significant difference noted (p < 0.001). Additionally, the rate of patients readmitted to the hospital within the first 30 days was 16 (21.6%) in the CG and 7 (9.5%) in the OG, with a significant difference observed (p = 0.041). Conclusion: In terms of bleeding requiring intervention, there was no difference between omentopexy and clipping techniques. In addition, omentopexy showed more satisfactory results than clipping in terms of non-interventional bleeding, but its clinical significance is unclear. [ABSTRACT FROM AUTHOR]

Purpose: Reflux after laparoscopic sleeve gastrectomy (LSG) may result from anatomical and functional anomalies in the gastric conduit. Three-dimensional CT scans (3DCT) offer a comprehensive view of gastric anatomy. This study aims to establish specific measurements associated with sleeve abnormalities to standardise the reporting of 3DCT which may help in management of LSG complications. Materials and Methods: This retrospective study analysed 64 post-LSG patients who underwent gastric 3DCT. Data included clinical demographics, pre-LSG BMI, BMI at 3DCT, and the duration between surgery and examination. Symptomatology prompts the scan and other concurrent investigations. Various 3DCT measurements were taken, including angularis angle (AA), surface area (ASA), conduit length (CL), proximal maximal surface area (PMSA), and distal maximal surface area (DMSA) of the gastric conduit. Patients were categorised based on endoscopy findings and symptomatology. Outcomes post-revisional surgery were assessed and analysed. Results: 20.3% were male. Pre-LSG BMI and BMI at 3DCT were 45.57 (± 8.3) and 36.3 (± 8.7), respectively. Mean surgery-to-scan period was 6.2 years. 71.8% of patients presented with reflux, regurgitation, or dysphagia, whilst the remainder primarily exhibited weight regain. Patients with endoscopic evidence of stenosis/reflux demonstrated significantly lower gastric volume, ASA, and DMSA (p = 0.002 and p = 0.007, respectively). Oesophageal diameter above the conduit and an ASA to DMSA ratio ≤ 0.5 were negatively associated with AA (p = 0.008 and p = 0.08, respectively). Patients with improved outcomes after revisional bypass and gastrogastrostomy displayed a negative correlation with ASA and positive correlation with the ASA to PMSA ratio (≤ 0.5). Conclusion: 3DCT measurements have a potential role in defining post-LSG stenosis and predicting outcomes of revisional surgery. Patients with anatomic abnormalities that are shown on CT appear to improve with anatomic correction. [ABSTRACT FROM AUTHOR]

This systematic review aims to evaluate the current evidence regarding safety and efficacy of magnetic sphincter augmentation (MSA) for the treatment of gastroesophageal reflux disease (GERD) after laparoscopic sleeve gastrectomy (LSG). Conversion to Roux-en-Y gastric bypass (RYGB) carries the risk of surgical and metabolic complications and may be contraindicated in patients with normalized or near-normalized body mass index. The LINX™ procedure aims to restore LES competency and to repair the crura. We included 109 patients (14 studies) undergoing LINX™ implant after LSG. Median follow-up was 18.9 months (range 0.3–63). Both the GERD-HRQL (38 ± 13 vs. 10 ± 11; p = 0.0078) and daily PPI use (97.4% vs. 25.3%; p < 0.0001) were significantly improved. Overall, 31.8% of the patients experienced device-related adverse events, mainly self-limiting. LINX™ explant for esophageal erosion occurred in 0.9% of the patients. [ABSTRACT FROM AUTHOR]

Background: Laparoscopic BariClip gastroplasty (LBCG) is a new reversible bariatric procedure designed to replicate the restrictive effects of laparoscopic sleeve gastrectomy (LSG) by placing a clip vertically on the stomach. This technique achieves gastric lumen restriction without the need for resection, ensuring organ preservation and reversibility. However, concerns have arisen regarding potential complications such as gastroesophageal reflux disease (GERD), slippage, or erosion of the stomach. The aim of the study is to evaluate the outcomes and complications of LBCG. Methods: This is a monocentric retrospective study. We analyzed 149 patients who underwent LBCG procedure between July 2021 and November 2023. A minimum follow-up period of 6 months was observed for all patients, recording clinically relevant GERD through GERD-Q score questionnaires. Weight loss was monitored through body mass index (BMI) and % total weight loss (%TWL), registered during follow-up visits. Results: Overall, 149 patients were eligible for this study. Overall complication rate was 8% (12/149). The average BMI went from 40 ± 4.37 kg/m2 to 28 ± 4.29 kg/m2 (p < 0.05) in 6 months, while the mean %TWL was 22.6% after at least 6 months of follow-up. Clinically relevant GERD went from 18.1% (27/149) to 10.7% (16/149), p = 0.1262. As expected, also the PPI usage was not altered significantly (17.8% vs 16.4%), p = 0.8714. Conclusions: LBCG remains an experimental procedure that must be approached with caution. Nonetheless, the potential of LBCG to reproduce the effects of LSG while reducing GERD makes it a promising new reversible option for the treatment of morbid obesity. [ABSTRACT FROM AUTHOR]

Background: Metabolic bariatric surgery (MBS) advocates multimodal analgesia, discouraging opioid use to minimize side effects, such as nausea and vomiting, during postoperative pain management for quicker recovery. Combining erector spinae plane block (ESPB) with multimodal analgesia aims to reduce opioid consumption, improving postoperative recovery. This study aimed to compare morphine consumption between patients with severe obesity undergoing laparoscopic MBS with and without ESPB. Methods: This study enrolled 91 patients with severe obesity who underwent laparoscopic MBS involving either sleeve gastrectomy or Roux-en-Y gastric bypass. Of these, 63 patients were included in this study. The participants were randomly allocated to either the intervention group, which received an ESPB before the standard anesthesia protocol, or the control group, which did not receive pre-anesthesia block. The primary outcome measured was 24-h morphine consumption via a patient-controlled analgesia machine. Secondary outcomes included patients' satisfaction, postoperative numerical rating score, changes over time, and quality of recovery (QoR) using the Thai QoR-35 score. Results: We found no statistically significant difference in morphine consumption between the intervention group and the control group. Furthermore, our analysis revealed no significant between-group differences in patient satisfaction, postoperative numeric rating score, or QoR across all five aspects evaluated using the Thai QoR-35 score. Conclusions: ESPB did not reduce morphine consumption or QoR following laparoscopic MBS. Further studies are required to confirm and identify the reasons for the ineffectiveness of ESPB.

Objective: Grit is a person's ability to establish long-term goals and work to achieve those goals irrespective of any barriers. We examined the relationship between the personality trait grit, obesity, and metabolic and bariatric surgery (MBS)–induced weight loss. Methods: In an ongoing prospective cohort, 104 adult patients who underwent laparoscopic sleeve gastrectomy (LSG) had preoperative grit questionnaires administered. The association between grit domains and 1-year weight loss was evaluated by ANCOVA. Results: Among the 104 patients who completed a pre-operative grit survey, 74 completed the survey again 1 year after surgery (72.1%). One year percent total body weight loss (TBW) was 28.4% for the entire cohort and 27.9% for the 74 patients who had complete follow-up at 1 year. Grit scores were not significantly different between baseline and postoperative measurements (pre-op 3.69 ± 0.68 versus post-op 3.67 ± 0.67). Neither the pre-operative total grit score nor its major domains consistency of interests and perseverance of effort were associated with 1-year weight loss (r = 0.034, P = 0.733). Conclusions: There was no correlation between grit and MBS-induced weight loss at 1 year after surgery. As a physiologic solution, MBS may result in weight loss independent of a person's ability to set long-term goals and achieve those goals. [ABSTRACT FROM AUTHOR]

Background: Glucocorticoid metabolites are associated with body composition measures and are altered with weight status. Metabolic and bariatric surgery (MBS) results in significant changes in weight and body composition. However, MBS effects on glucocorticoid metabolites are unknown. Objective: To evaluate (i) changes in the cortisol/cortisone ratio in youth with obesity 12 months after sleeve gastrectomy (SG) compared with nonsurgical controls with obesity (NS), and (ii) associations of these changes with body composition changes. Methods: A total of 38 participants 13–25 years old with obesity (29 female) were followed for 12 months. Half underwent SG, and the other half were followed with routine care (nonsurgical, NS). Fasting blood was assessed for cortisol and cortisone using liquid chromatography-mass spectroscopy as part of metabolomic analysis, and the cortisol/cortisone ratio was calculated. A single-slice MRI of the abdomen was performed to assess subcutaneous and visceral adipose tissue (SAT, VAT). Hepatic steatosis was assessed by computed tomography (CT). Results: SG did not differ from NS for baseline clinical characteristics, other than the mean age (SG 18.0 ± 0.46 vs. NS 16.6 ± 0.50 years, P = 0.041), BMI (BMI, 47.23 ± 1.5 vs. 41.32 ± 1.1 kg/m2, P = 0.003) weight and VAT, which were higher in SG. Significant reductions were noted over 12 months in BMI, BMI z-score, VAT, and SAT within the SG versus NS groups (P ≤ 0.001). Over 12 months, groups did not differ for changes in cortisol/cortisone ratio after controlling for age at baseline (P = 0.293). The ratio trended to decrease within the SG group [−1.40 (−5.08, 0.06), P = 0.080], particularly among those that had completed puberty (P = 0.048). No associations were found between changes in the cortisol/cortisone ratio and changes in body composition. Conclusions: The cortisol/cortisone ratio trended to decrease 12 months following SG. However, no associations were found between changes in the cortisol/cortisone ratio and changes in body composition. Studies with larger numbers of participants are necessary to confirm these findings. [ABSTRACT FROM AUTHOR]

Objective: The objective of this study was to assess maternal gestational outcomes and offspring growth trajectories following prepregnancy metabolic and bariatric surgery (MBS) compared with non‐MBS controls. Methods: Single‐center deliveries between January 2020 and March 2023 with prepregnancy Roux‐en‐Y gastric bypass (herein referred to as "bypass"), sleeve gastrectomy (herein referred to as "sleeve"), and non‐MBS controls were included. Offspring growth trajectories were compared with the World Health Organization child growth standards. Linear mixed models assessed MBS‐bypass and MBS‐sleeve offspring weight, length, and BMI trajectories with a prepregnancy BMI 27 to 37 kg/m2 and propensity score‐matched controls. Results: The study included 440 participants with prepregnancy MBS (MBS‐bypass, 185; MBS‐sleeve, 225; 76% Hispanic/Latino) and 13,434 non‐MBS controls. Gestational weight gain and gestational diabetes mellitus were similar, whereas hypertensive disorders of pregnancy were more common after MBS. The post‐MBS offspring had lower birth weight but higher weight gain at 24 months (sleeve, +1.4 kg [95% CI: 1.0–1.9]; bypass, +0.5–0.7 kg [95% CI: 0.0–1.2]) compared with non‐MBS groups. Male children had higher weight gain than females. The post‐MBS‐sleeve but not the post‐MBS‐bypass offspring had higher BMI z scores. Conclusions: The higher early‐life weight gain and sex differences in the post‐MBS‐sleeve group compared with the post‐MBS‐bypass group provide a window toward elucidating pathways to mitigate intergenerational metabolic risk transfer.

Background Gastroesophageal reflux disease (GERD) is among the most common complications of bariatric surgery. This study aimed to analyse the risk factors affecting the worsening of GERD symptoms after laparoscopic sleeve gastrectomy (LSG), and to establish and validate a related nomogram model. Methods The study recruited 236 participants and randomly divided them into training and validation sets in a ratio of 7:3. LASSO regression technique was used to select the optimal predictive features, and multivariate logistic regression was used to construct the column line graphs. The performance of the nomogram was evaluated and validated by analyzing the area under the receiver operating characteristic (ROC) curve, calibration curve, and decision curve. Results In this study, Lasso-logistic regression was applied to select 5 predictors from the relevant variables, which were body mass index (BMI), diabetes, hiatal hernia, GERD, and triglyceride levels. These 5 predictor variables constructed a model with moderate predictive power, with an area under the ROC curve of 0.779 for the training set and 0.796 for the validation set. Decision curve analysis showed that in external validation, if the risk thresholds were between 4 and 98% and 14–95%, then the nomogram can be applied to the clinic. Conclusions We have developed and validated a nomogram that effectively predicts the risk of worsening gastroesophageal reflux symptoms following LSG. [ABSTRACT FROM AUTHOR]

Introduction: Renal dysfunction is a recognized complication of obesity with an incompletely characterized pathophysiology. Improvement of glomerular filtration rate (GFR) after metabolic and bariatric surgery (MBS) has been reported across all classes of renal function. Inter-gender differences with regard to correlates of renal function have been described, but the influence of body composition is an understudied area. We aimed to explore determinants of renal function in obesity and to assess its variations after MBS, with a focus on body composition parameters in males and females, respectively. Materials, methods: We conducted a retrospective study on 196 patients who underwent laparoscopic sleeve gastrectomy, evaluated preoperatively and 6 months after the intervention. Recorded data included clinical and biochemical assessment, as well as body composition estimation via dual-energy X-ray absorptiometry. Serum creatinine-based formulas were used for the estimation of GFR. Results: We included a total of 196 patients (80 males and 116 females), with a mean age of 41.43 ± 10.79. Median baseline body mass index was 42.6 (6.61) kg/ m2 and 6 months excess weight loss (EWL) reached 71.43 ± 17.18%, in females, estimated GFR correlated negatively with visceral adipose tissue (VAT) mass (rho=-.368) and this correlation was stronger in females with type 2 diabetes mellitus. Moreover, women in the third VAT mass tertile were 5 times more likely to have reduced GFR compared to the first tertile. Renal function improved after MBS across all classes of filtration. In males, this improvement correlated with EWL (rho=.358) and lean mass variation (rho=-.412), while in females it correlated with VAT mass variation (rho=-.266). Conclusions: Our results are consistent with previous findings on the positive impact of MBS on renal function and suggest a more prominent impact of visceral adiposity on GFR in females.

Background: Although numerous studies have shown that bariatric surgery results in sustained weight loss and modifications in gut microbiota composition and cognitive function, the exact underlying mechanisms are unclear. This study aimed to investigate the effects of bariatric surgery on cognitive function through the microbiota-gut-brain axis (MGBA). Methods: Demographic data, serum samples, fecal samples, cognitive assessment scales, and resting-state functional connectivity magnetic resonance imaging (rs-fMRI) scans were obtained from 39 obese patients before and after (6 months) laparoscopic sleeve gastrectomy (LSG). PCA analysis, OPLS-DA analysis, and permutation tests were used to conduct fecal 16 S microbiota profiling, serum metabolomics, and neuroimaging analyses, and a bariatric surgery-specific rs-fMRI brain functional connectivity network was constructed. Spearman correlation analysis and Co-inertia analysis were employed to correlate significant alterations in cognitive assessment scales and resting-state functional connectivity difference networks with differential serum metabolites and 16 S microbiota data to identify key gut microbiota and serum metabolic factors. Results: LSG significantly reduced the weight of obese patients, with reductions of up to 28%. Furthermore, cognitive assessment scale measurements revealed that LSG enhanced cognitive functions, including memory (HVLT, p = 0.000) and executive function (SCWT, p = 0.008). Also, LSG significantly altered gut microbiota composition (p = 0.001), with increased microbial abundance and diversity (p < 0.05). Moreover, serum metabolite levels were significantly altered, revealing intergroup differences in 229 metabolites mapped to 72 metabolic pathways (p < 0.05, VIP > 1). Spearman correlation analysis among cognitive assessment scales, gut microbiota species, and serum metabolites revealed correlations with 68 gut microbiota species and 138 serum metabolites (p < 0.05). Furthermore, pairwise correlations were detected between gut microbiota and serum metabolites (p < 0.05). Functional neuroimaging analysis revealed that LSG increased functional connectivity in cognitive-related frontotemporal networks (FPN, p < 0.01). Additionally, normalization of the default mode network (DMN) and salience network (SN) connectivity was observed after LSG (p < 0.001). Further canonical correlation and correlation analysis suggested that the cognitive-related brain network changes induced by LSG were associated with key gut microbiota species (Akkermansia, Blautia, Collinsella, Phascolarctobacterium, and Ruminococcus, p < 0.05) and neuroactive metabolites (Glycine, L-Serine, DL-Dopa, SM (d18:1/24:1(15Z), p < 0.05). Conclusion: These findings indicate the pathophysiological role of the microbiota-gut-brain axis in enhancing cognitive function after bariatric surgery, and the study provides a basis for clinical dietary adjustments, probiotic supplementation, and guidance for bariatric surgery, but further research is still needed.

Background: Refeeding syndrome (RFS) and starvation-associated injuries are significant complications in malnourished patients. Severe weight loss after obesity surgery is frequently associated with malnutrition, consequently increasing the likelihood of RFS and starvation-related injuries as postoperative complications. RFS and starvation-induced injury in a single patient has rarely been reported. In this paper, we present, for the first time, a case of hepatic injury attributed to both refeeding syndrome and starvation-induced hepatic injury in a malnourished woman following bariatric surgery. Case Report: A 27-year-old female patient was admitted to the hospital for severe malnutrition after sleeve gastrectomy. Her body mass index (BMI) dropped from 37.2 kg/m² to 12.4 kg/m² 1 year after surgery. After nutritional supplementation, her liver enzymes levels increased significantly, with severe hypophosphatemia suggesting the development of RFS. During the calorie restriction treatment for RFS, the patient unexpectedly exhibited the recurrent increase of liver enzyme levels and severe reduction in body weight, albumin, and hemoglobin, which is considered to be caused by starvation-induced injury during the treatment of RFS. Following precise nutritional re-supplementation, her liver enzyme levels were dramatically decreased, with significant elevated hemoglobin and albumin levels at discharge and during the follow-up visit. Conclusions: Chronic malnutrition and extreme weight loss can occur following bariatric surgery. Our report highlights the potential for RFS and starvation-related liver injuries as postoperative complications for high-risk patients after bariatric surgery. Liver injury can occur in both RFS and starvation-induced hepatitis. Nutrition initiation and supplementation should be carefully balanced in high-risk patients during nutritional treatments.

Bariatric surgery is vital for sustainable weight loss and metabolic improvement in obese individuals, but its effects on gut microbiota and their role in these benefits require further investigation. Investigate the temporal changes in gut microbiota in obese patients undergoing bariatric surgery (gastric sleeve gastrectomy or Roux-en-Y Gastric Bypass (RYGB)) compared to healthy controls, aiming to understand their role in weight loss and metabolic health improvement. A case-control study included 30 obese patients aged 65–95 undergoing bariatric surgery, and 18 matched healthy controls. Selection criteria were based on age, race, BMI, history of antibiotics, probiotics, and prebiotics usage. Stool samples were collected at baseline, three months, and six months post-surgery for DNA extraction and quantitative real-time PCR analysis to assess gut microbiota changes. Physical activity and dietary intake were evaluated using standardized questionnaires. Statistical analyses were performed using R. Post-surgery, patients showed significant reductions in weight and BMI, with changes in dietary habits and physical activity. Quantitative real-time PCR analysis revealed substantial alterations in bacterial groups such as Bacteroides and Fusobacterium. However, some groups showed no significant changes, indicating a complex interaction between gut microbiota and bariatric surgery. Notable correlations were found between body weight, BMI, and specific bacterial groups like the C. cluster IV and Lactobacillus, particularly in RYGB patients. Bariatric surgery significantly alters gut microbiota, aiding weight loss and metabolic regulation in obese patients. Understanding these changes is crucial for developing effective obesity management strategies, requiring further research to optimize outcomes. [ABSTRACT FROM AUTHOR]

Background: Obesity is a growing health concern in China, closely linked to metabolic disorders such as type 2 diabetes. Laparoscopic Sleeve Gastrectomy (LSG) is effective in promoting weight loss and improving metabolic outcomes. Emerging evidence highlights the role of gut microbiota in metabolic regulation, yet the specific alterations in gut microbiota and their association with metabolic changes post-surgery in Chinese patients remain unclear. Understanding these shifts could provide key insights into optimizing treatment strategies for metabolic improvement following bariatric surgery. Methods: Stool samples and clinical data were collected from 30 obese patients before and 6 months after surgery. The composition of the gut microbiota was analyzed through 16S rRNA sequencing, and Spearman correlation analysis was used to determine the association between gut microbiota and clinical indicators. Results: The analysis of 30 patients showed a significant decrease in Body Mass Index (BMI) (36.75 ± 4.09 kg/m2 vs 26.37 ± 3.47 kg/m2, p < 0.0001). Glucose metabolism, including Hemoglobin A1C levels, improved significantly (6.05 ± 0.96 vs 5.05 ± 0.25, p < 0.0001), and liver function as well as serum lipid levels were also notably improved. LSG increased the richness and composition of gut microbiota in obese patients post-surgery. These changes in gut microbiota were closely associated with improved clinical metabolic parameters. Conclusion: LSG not only significantly reduces body weight while also alleviating metabolic syndrome and comorbidities by altering gut microbiota. [ABSTRACT FROM AUTHOR]

Background Methods Results Conclusions The prevalence of overweight and obesity and an unhealthy diet and lifestyle are the key causes of rising diabetes burden in India. Bariatric surgery is gaining popularity in India as a favored approach to manage obesity and its accompanying comorbidities. Despite this, there is a scarcity of Indian studies evaluating dietary intake. Our goal was to analyse the dietary intake of Indian patients with type 2 diabetes mellitus (T2DM) who have undergone laparoscopic sleeve gastrectomy (LSG) or duodeno‐jejunal bypass with sleeve gastrectomy (DJB‐SG) or surgeries.The longitudinal observational study included 64 T2DM patients (32 in each procedure) enrolled through purposive sampling. The patients underwent surgery (LSG or DJB‐SG procedure) between January 2017 and July 2019. Dietary data was collected at baseline and postsurgery (12 months) using a 24‐h dietary recall method for 2 days (one working and one holiday).The total sample consisted of 27 (42.2%) females and 37 (57.8%) males. The mean age was 46.8 years. At 12 months, the follow‐up for the LSG and DJB‐SG procedures was 100% and 78%, respectively. In the short term, a significant reduction was seen in weight, body mass index and haemoglobin A1C (HbA1C) in both surgical groups. The two procedures were comparable with respect to weight loss but improvement in glycaemia was higher in the DJB‐SG group. The dietary intake (food groups and nutrients) was similar in the two surgical groups at baseline and 12 months postsurgery. Dietary intake assessment showed significant reduction in calorie dense foods (cereals, roots and tubers, fats and oils, table sugar, and biscuits) in both surgical groups. Among nutrients, intake of energy, fats, carbohydrates, dietary fibre, thiamine, riboflavin, niacin, folate and iron were reduced significantly in both procedures. Vitamin D (84.4% patients in LSG group and 81.3% patients in DJB‐SG) and iron (62.5% patients in LSG group and 68.8% patients in DJB‐SG) were commonly prevalent nutritional deficiencies at baseline and were significantly reduced at 12 months.In the short term, bariatric surgery resulted in weight loss and improvement in glycaemia. Bariatric surgery does significantly affect dietary intake leading to nutritional deficiencies. Therefore, patients should be recommended vitamin and mineral supplements and regular patient education and counselling by a trained bariatric dietitian to prevent nutritional deficiencies and maintain nutritional status.

Background: Sleeve gastrectomy (SG) has become the predominant bariatric surgery, leading to significant weight loss and reductions in obesity-related complications. However, postoperative gastrointestinal symptoms such as constipation and bloating are common. This study aims to evaluate the impact of probiotic supplementation on postoperative gastrointestinal symptoms in patients undergoing SG. The secondary aim is to analyze laboratory and stool test results. Materials and methods: This prospective, placebo-controlled study included patients undergoing SG at a single center. Participants were adults without specific gastrointestinal diseases. They were randomly assigned to either the Probiotics or Controls group. Gastrointestinal symptoms and laboratory and stool tests were assessed before surgery and one month after. Results: Thirty-one patients participated, with 15 in the Probiotics group and 16 in the Controls group. Probiotic supplementation significantly increased the number of stools per week (p = 0.027) and reduced constipation incidence (p = 0.002). Patients in the Probiotics group reported easier defecation and greater bowel movement completeness (p = 0.015, p = 0.004). No significant differences in weight loss or laboratory tests were observed between the groups. Stool microbiota analysis showed a return to normal levels of Enterococcus faecalis, Enterococcus faecium, and Clostridium perfringens in the Probiotics group and an increase in the Controls group. Conclusions: Probiotic supplementation after SG significantly reduces constipation without adverse effects. These findings suggest that incorporating probiotics into postoperative care protocols can enhance patient comfort and recovery. [ABSTRACT FROM AUTHOR]

Summary Dumping and post‐bariatric hypoglycaemia (PBH) are side effects that occur after bariatric surgery. The aim of this study was to estimate the prevalence of dumping and PBH symptoms before Roux‐en‐Y gastric bypass (RYGB) and sleeve gastrectomy (SG) at 6 months, 1 year, 2 years and 5 years after surgery in a Swedish population. A cross‐sectional single‐centre study was performed at Lindesberg Hospital, Region Örebro County, Sweden, between 2020 and 2023. The Swedish version of the Dumping Severity Scale (DSS‐Swe) questionnaire, which includes eight items regarding dumping symptoms and six items regarding hypoglycaemia symptoms, was used. A total of 742 DSS‐Swe questionnaires were included. The average age at surgery was 42.0 years (standard deviation [SD] = 11.9), and the average body mass index was 41.8 kg/m2 (SD = 5.9). The surgical methods consisted of RYGB (66.3%) and SG (33.7%). The proportion of RYGB patients with highly suspected dumping increased from 4.9% before surgery to 26.3% (adjusted odds ratio [OR] = 7.35, 95% confidence interval [CI] = 3.08–17.52) at the 5‐year follow‐up. PBH symptoms increased from 1.4% before surgery to 19.3% at the 5‐year follow‐up (adjusted OR = 17.88, 95% CI = 4.07–78.54). For SG patients, no significant increase in dumping or PBH symptoms was observed. In patients with persistent type 2 diabetes (T2D), there were no cases of highly suspected hypoglycaemia following RYGB or SG. Symptoms of dumping and PBH were common after RYGB, while no clear increase was observed after SG. Persistent T2D seems to be a protective factor against PBH symptoms. [ABSTRACT FROM AUTHOR]

Introduction: Evidence from Asian studies suggests that minimally-invasive gastrectomy achieves equivalent oncological but improved perioperative outcomes compared to open surgery. Oncological gastric resections are less frequent in European countries. Index procedures may play a role for the learning curve of minimally-invasive gastrectomy. The aim of our study was to evaluate if skills acquired in bariatric surgery allow a safe and oncologically adequate implementation of minimally-invasive gastrectomy in a cohort of european patients. Methods: In this single-center retrospective study, all patients who received primary bariatric surgery between January 2015 and December 2018 and minimally-invasive surgery for gastric cancer treated from June 2019 to January 2023 were evaluated. Primary endpoints were operation time, lymph node yield and lymph node fractions. Secondary endpoints included postoperative complications and oncological outcomes. Results: Learning curves for two surgeons with 350 bariatric procedures and 44 minimally-invasive gastrectomies were analyzed. For bariatric surgery, the mean operation time decreased from initially 82 ± 27 to 45 ± 21 min and 118 ± 28 to 81 ± 36 min for sleeve gastrectomy (SG) and Roux-en-Y gastric bypass (RYGB), while the complication rate remained within the international benchmark. For laparoscopic gastrectomy (n = 30), operation times decreased but then remained stable over time. Operation times for the robotic platform were longer (302 ± 60 vs. 390 ± 48 min; p < 0.001) with the learning curve remaining incomplete after 14 procedures. R0 status was achieved in 95.5% of patients; the mean number of lymph nodes retrieved was 37 ± 14 with no differences between the groups. Complete mesogastric excision was more frequently achieved during the later laparoscopic cases whereas it occurred earlier for the robotic group (p = 0.004). Perioperative morbidity was comparable to the European benchmark. Textbook outcome was achieved in 54.4% of the cases. Conclusion: In summary, we could demonstrate a successful skill transfer from bariatric surgery to minimally-invasive laparoscopic oncological gastric surgery enabling safe and oncologically adequate minimally-invasive D2 gastrectomy in a central European patient collective.

Aim Methods Results Conclusion To investigate the effect of preadmission education given to laparoscopic sleeve gastrectomy patients on preoperative and postoperative anxiety, postoperative pain, and patient vital signs.The study was designed as randomized, controlled, experimental, and single‐blind. This study was conducted with 68 patients who met the inclusion criteria and underwent laparoscopic sleeve gastrectomy in the general surgery clinic of a university hospital between December 2022 and October 2023. Data were collected using the ‘Perioperative Form,’ ‘Visual Analog Scale,’ and ‘State Anxiety Scale I‐II.’ Intervention group patients were informed and educated about the surgical process in the outpatient clinic. The anxiety levels of all patients were determined with the State Anxiety Scale the day before surgery. In the postoperative period, vital signs (once), anxiety (on the first day after surgery), and pain levels (eight times during 48 h) were measured.In the analysis between the groups, the difference between the duration of postoperative hospital stay (p = 0.007), pain (p = 0.000 for all measured), and anxiety levels (p = 0.000) was statistically significant. There were also significant differences in the diastolic blood pressure (p = 0.007), body temperature (p = 0.000), and saturation values (p = 0.000). Patients' readiness level for surgery was the most influential factor in postoperative pain levels (p = 0.000).The education given to the patients before hospitalization decreased preoperative and postoperative anxiety levels, postoperative hospital stay and pain levels, and positively affected diastolic blood pressure, body temperature and saturation levels. One‐to‐one education given to patients in the outpatient clinic also contributes positively to their readiness for surgery. This study provides valuable evidence to the wider global clinical community by demonstrating the important benefits of preadmission education for patients undergoing bariatric surgery. Implementation of similar educational interventions in diverse healthcare settings worldwide may lead to increased postoperative recovery and improved overall patient well‐being after bariatric surgery.

Summary: We evaluated preoperative weight loss and days from initial consult to surgery in patients with BMI ≥50 kg/m2 who were and were not enrolled in medical weight management (MWM) prior to laparoscopic sleeve gastrectomy. We retrospectively identified patients with BMI ≥50 kg/m2 who had primary sleeve gastrectomy between 2014 and 2019 at two bariatric surgery centres in our healthcare system. Patients presenting after 2017 that received preoperative MWM (n = 28) were compared to a historical cohort of non‐MWM patients (n = 118) presenting prior to programme initiation in 2017 on preoperative percent total body weight loss (%TBWL) and days from initial consult to surgery. A total of 151 patients (MWM, 33; non‐MWM, 118) met inclusion criteria. BMI was significantly greater in MWM versus non‐MWM (p =.018). After propensity score matching, median BMI at initial consult in non‐MWM versus MWM no longer differed (p =.922) neither were differences observed on the basis of weight, age, sex, race or ethnicity. After PSM, MWM had significantly lower BMI at surgery (p =.018), lost significantly more weight from consult to surgery (p <.001) and achieved significantly greater median %TBWL from consult to surgery (p <.001). We noted no difference between groups on 6‐month weight loss (p =.533). Days from initial consult to surgery did not differ between groups (p <.863). A preoperative MWM programme integrated into multimodal treatment for obesity in patients with a BMI ≥50 kg/m2 resulted in clinically significant weight loss without prolonging time to surgery.

The prevalence of obesity in Korea has steadily increased over the past decade, reaching 38.4% in 2021. Notably, the rate of class II– III obesity, defined as a body mass index (BMI) of 30 kg/m² or higher, exceeded 7% in the same year. Since January 2019, the National Health Insurance Service (NHIS) has provided coverage for bariatric surgery (BS) for eligible patients. Coverage is available for individuals with a BMI of 35 kg/m² or higher, or those with a BMI of 30 kg/m² or higher who also have obesity-related comorbidities. Additionally, partial reimbursement is offered for BS in patients with type 2 diabetes mellitus who have BMI values between 27.5 and 30 kg/m². From 2019 to 2022, the NHIS recorded 9,080 BS procedures, with sleeve gastrectomy being the most commonly performed. The average percentage of weight loss 198±99.7 days post-surgery was 17.9%, with 80.0% of patients losing more than 10% of their body weight. This article presents the trends in obesity and BS in Korea. [ABSTRACT FROM AUTHOR]

Gastrectomy, a prevalent surgical procedure for gastric cancer, results in substantial alterations to the gastrointestinal tract, including reduced gastric acid production and significant modifications to the gut microbiota. These changes can impair postoperative recovery, influence metabolic functions, and predispose patients to inflammatory bowel disease (IBD). Studies have shown an increased risk of IBD, particularly Crohn's disease (CD) and ulcerative colitis (UC), in patients following gastrectomy and bariatric surgeries such as Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG). For instance, patients undergoing RYGB have a higher hazard ratio for developing CD, while SG patients show an increased risk for UC. The surgical alteration of the gastrointestinal tract promotes dysbiosis, with a significant increase in pathogenic bacteria and a decrease in beneficial microbial populations. This dysbiosis can impair the intestinal mucosal barrier and promote systemic inflammation. Understanding the mechanisms behind these changes and their clinical implications is essential for developing effective postoperative management strategies. Probiotics and enhanced recovery after surgery (ERAS) protocols have shown promise in mitigating these adverse effects, improving gut microbiota balance, and enhancing patient outcomes. Further research is necessary to fully elucidate the long-term impacts of gastrectomy on gastrointestinal health and to refine therapeutic approaches for postoperative care. [ABSTRACT FROM AUTHOR]

Background: Surgical audit is key in upholding the standards of surgical care but may be inadequate in capturing morbidity experienced by patients being transferred across different health systems. The aim of this study was to assess the utility of an objective framework in the evaluation of clinical issues surrounding interhospital transfers (IHTs). Methods: A retrospective cohort study was conducted at a Victorian state bariatric hospital. Patients transferred with bariatric surgery related complications between 2014 and 2021 were included. Each case was reviewed by two surgeons using an objective framework developed via a modified Delphi‐process. Key issues and preventability surrounding each transfer were evaluated. Inter‐observer agreement was assessed using weighted Cohen's Kappa coefficient. Results: Seventy‐three patients were included. The most common indication for transfer was proximal staple line leak post sleeve gastrectomy (34/73, 46.6%). Length of stay was 38.3 ± 58.8 days. Cost of care amounted to AUD $110 666.18 per patient. Delay in transfer and complication recognition were present in 20% of cases (Cohen's Kappa 0.51;0.61). Human factors and patient related factors were the most common principal underlying causes (Cohen's Kappa 0.59). A third of the complications (n = 25/73, 34.2%), were potentially preventable (Cohen's Kappa 0.58) and more than half (39/73, 53.4%) did not have documented objective feedback to referring clinicians. Conclusion: IHTs associated with bariatric surgery complications have significant morbidity and costs. A structured framework in reviewing IHT can consistently identify potentially modifiable factors that improve clinical outcomes, and constructive feedback to the referring clinician should be actively facilitated and documented.

Morbid obesity in infancy or early childhood is a challenging disease to manage. Here, we present the case report of the successful management of a 2‑year‑old girl child with morbidly obesity who was bedridden and had sleep apnoea and underwent laparoscopic sleeve gastrectomy. Bariatric surgery in this age group comes with a lot of decision‑making challenges and technical and ethical considerations, and literature is scant on paediatric bariatric surgery. We describe the case and associated challenges in detail in this report. [ABSTRACT FROM AUTHOR]

The use of robotic surgery has increased worldwide and has the potential to amplify the surgeon’s skill owing to its versatile functions. However, robotic surgery requires specific skills that differ from laparoscopic surgery, and the field of robotic surgery training systems is underdeveloped. Therefore, to ensure patient safety, a task protocol should be prepared before the introduction of novel robotic surgeries. This article provides the pioneering description of performing robotic sleeve gastrectomy (RSG) through the medial‑to‑lateral approach, utilising our newly revised protocol. The preliminary clinical results of 10 patients who underwent RSG using the stapling‑first technique between June 2021 and March 2023 showed that RSG is safe and feasible and that the implementation of a task protocol is an effective strategy for the safe introduction of a novel robotic surgical technique.

Introduction: Our study aimed to compare the short‑ and particularly long‑term type 2 diabetes mellitus (T2DM) remission prediction abilities of ABCD, individualised metabolic surgery (IMS), DiaRem2, Ad‑DiaRem and DiaBetter scoring systems in Turkish adult type 2 diabetic morbidly obese patients who underwent bariatric surgery. Patients and Methods: Our study was planned as a retrospective cohort study. A total of 137 patients with T2DM, including 78 sleeve gastrectomy (SG) and 59 Roux‑en‑Y gastric bypass (RYGB) patients, were included in the 1st‑year evaluation after bariatric surgery, and a total of 115 patients with T2DM, including 64 SG and 51 RYGB patients, were included in the evaluation at the end of the 5th year. Results: In the 1st year after bariatric surgery, area under the ROC curve (AUC) values for diabetes remission scores were 0.863 for Ad‑DiaRem, 0.896 for DiaBetter, 0.840 for DiaRem2, 0.727 for ABCD and 0.836 for IMS. At 5 years after bariatric surgery, the AUC values for diabetes remission were 0.834 for Ad‑DiaRem, 0.888 for DiaBetter, 0.794 for DiaRem2, 0.730 for ABCD and 0.878 for IMS. Conclusions: According to our study, the DiaBetter score provided a better AUC value than the other scores both in the short and long term but showed similar predictive performance to Ad‑DiaRem in the short term and IMS in the long term. We believe that DiaBetter and Ad‑DiaRem scores might be more appropriate for short‑term assessment and DiaBetter and IMS scores for long‑term remission assessment. [ABSTRACT FROM AUTHOR]

Background—Gastroesophageal reflux disease (GERD) is commonly diagnosed in patients with severe obesity. The outcomes of patients with preoperative GERD after sleeve gastrectomy (SG) are unclear, and some surgeons consider GERD a contraindication for SG. Methods—A retrospective analysis of a tertiary university hospital database was conducted. All patients with preoperative GERD undergoing SG between January 2012 and January 2020 and having at least two years of follow-up were included in the analysis. A validated GERD-associated quality of life questionnaire (GERD-HRQL) was completed by all patients. Results—During the study period, 116/1985 patients (5.8%) were diagnosed with GERD before SG. In total, 55 patients were available for a two-year follow-up and were included in the analysis. Median follow-up was 40 months (range 24–156 months). Mean total weight loss (TWL) was 24.0% ± 12.0%. On follow-up, 43 patients (78.1%) reported having GERD symptoms. In patients who underwent postoperative endoscopy, less than a third had esophagitis. The mean GERD-HRQL score was 25.2 ± 10.9. On univariable analysis, patients with poor GERD-HRQL had lower BMI at baseline (41.5 ± 12.4 vs. 44.9 ± 10.0 kg/m2, p = 0.03), were less commonly smokers at baseline (8.1% vs. 33.3%, p = 0.02), and had lower TWL at the end of the follow-up (22.2% ± 10.4% vs. 28.9% ± 13.7%, p = 0.05). On multivariable analysis, smoking status at baseline and TWL at last follow-up were independent predictors of better GERD-HRQL. Conclusions—In conclusion, most GERD patients after SG have a relatively high GERD-HRQL score, most patients still have GERD symptoms during the follow-up, and approximately a third of patients have endoscopic signs of esophagitis. There was an association between patients with higher TWL and smoking at baseline and better GERD-HRQL outcomes. The latter is potentially due to smoking cessation. [ABSTRACT FROM AUTHOR]

Background/Objectives: Metabolic syndrome, defined by the coexistence of central obesity, dyslipidemia, hypertension, and insulin resistance, is a significant contributor to increased cardiovascular morbidity and mortality in the aging population. We aimed to determine whether age influences the efficacy of LSG in treating obesity-related comorbidities. Methods: A retrospective analysis of lipid profiles, glycemic and clinical parameters was conducted in a group of 786 patients in two age groups (under 50 years old and over 50 years old) who underwent laparoscopic sleeve gastrectomy with follow-ups 1, 3, 6, 12 and 24 months after surgery. Results: There was a significant improvement in lipid metabolism with no significant differences between the two age groups in these parameters throughout the observation period. Furthermore, there was significant weight loss (54.82 kg vs. 54.56 kg) and BMI reductions (47.71 kg/m2 vs. 47.01 kg/m2 to 29.03 kg/m2 vs. 30.73 kg/m2). Total cholesterol decreased from 198 mg/dL to 184.9 mg/dL (<50 years old) and from 206.4 mg/dL to 193 mg/dL (>50 years old). LDL dropped from 136.2 mg/dL to 116.7 mg/dL and from 141.0 mg/dL to 121.0 mg/dL. Mean HbA1c decreased to comparable levels (5.66% vs. 5.53%). Both groups showed similar rates of remission for type 2 diabetes and hypertension. Conclusions: Our findings suggest that LSG is an effective method for treating components of metabolic syndrome regardless of age, supporting its use as a therapeutic tool for older patients.

Introduction: Uncomplicated surgical approaches that minimize anastomotic complications while improving revisional metabolic/bariatric surgical (MBS) outcomes are needed. Methods: This prospective single‐center study assessed the feasibility, safety, and efficacy of the novel linear magnetic anastomosis system (LMAS [3 cm]) in performing a side‐to‐side duodeno‐ileostomy (MagDI) bipartition to revise clinically suboptimal primary sleeve gastrectomy (SG). Patients with severe obesity with/without type 2 diabetes (T2D) with suboptimal weight loss, regain, and/or T2D recurrence post SG underwent revisional MagDI. A distal and proximal magnet were delivered endoscopically to the ileum and duodenum and aligned via laparoscopic assistance. Gradual magnet fusion formed a DI bipartition. Primary endpoints: technical feasibility, safety (Clavien‐Dindo [CD] severe adverse event classification) at 1 year. Secondary endpoints: MBS weight and T2D reduction. Results: July 29, 2022–March 28, 2023, 24 patients (95.8% female, mean age 44.9 ± 1.5 years, and body mass index [BMI] 39.4 ± 1.3 kg/m2) underwent MagDI. Feasibility was attained via correct magnet placement (mean operative time 63.5 ± 3.3 min), patent anastomoses created, and magnet passage per anus in 100.0% of patients. There were 4 CD‐III mild or moderate severe AEs, 0.0% associated with the LMAS or MagDI: 0.0% anastomotic leakage, obstruction, bleeding, infection, reintervention, or death. Mean BMI reduction was 2.1 kg/m2 (p < 0.05); total weight loss 5.3%, excess weight loss 16.4%; and the patient with T2D improved. Conclusion: The single‐anastomosis MagDI procedure using the novel 3‐cm LMAS to revise clinically suboptimal SG was technically straightforward, incurred no major complications, mitigated weight regain, and renewed clinically meaningful weight loss.

According to recent data, one in eight people in the world struggle with obesity. Obesity management is increasingly dependent on bariatric surgical interventions, as the combination of lifestyle modifications and pharmacotherapy could have a modest long-term effect. Surgery is recommended only for individuals whose body mass index (BMI) ≥ 40 kg/m2 and ≥ 35 kg/m2 in the presence of weight-related comorbidities. The most commonly performed procedures are sleeve gastrectomy and roux-en-Y gastric bypass. Pharmacokinetic and pharmacodynamic alterations occur as a result of the anatomical and physiological changes caused by surgery, which further differ depending on physicochemical drug factors and factors related to the dosage form. The following modifications are distinguished based on the type of bariatric surgery performed. Most bariatric patients have accompanying comorbidities, including dyslipidemia treated with hydroxymethylglutaryl-coenzyme A (HMG-CoA) reductase inhibitors or statins. Significant improvements in the lipid profile are observed early in the postoperative period. The data reported in this review on statin pharmacokinetic alterations have demonstrated substantial inter- and intravariability, making it difficult to adopt clear guidelines. Based on the current literature review, reducing the statin dose to the lowest effective with continuous monitoring is considered an optimal approach in clinical practice. [ABSTRACT FROM AUTHOR]

Introduction: Obesity impairs patients' quality of life (QoL). Laparoscopic sleeve gastrectomy (LSG) is a common procedure for patients with severe obesity; however, studies reporting changes in obesity‐related QoL are limited. The aim of this study was to assess changes in obesity‐related QoL and food tolerance in the early postoperative period. Methods: We included 20 consecutive patients who underwent LSG between May 2021 and July 2023. We evaluated changes in obesity‐related QoL 6 months after surgery using an obesity and weight loss QoL questionnaire (OWLQOL) and a weight related symptom measure (WRSM). Additionally, we assessed eating satisfaction and food tolerance after surgery. Results: The percentages of total weight loss and excess weight loss were 28.5% and 79.1%, respectively. OWLQOL scores and WRSM changed from 36.5 to 73.0 points and from 44.0 to 15.0 points (p =.007,.007), respectively. The food tolerance score decreased from 25 to 21.2 points (p <.001), while eating satisfaction showed no significant change (p =.25). Conclusion: Obesity‐related QoL is enhanced even in the early postoperative period, without sacrificing eating satisfaction. The findings of this study may provide valuable insights for patients when considering LSG. [ABSTRACT FROM AUTHOR]

Background: Hiatal hernia repair (HHR) performed concurrently with vertical sleeve gastrectomy (VSG) has been shown to improve postoperative gastroesophageal reflux disease (GERD). However, data on the optimal extent of esophageal mobilization during repair are lacking. Mobilization techniques for HHR during VSG include partial (PM) or full (FM) mobilization of the esophagus. We hypothesize that patients who undergo full mobilization will be less likely to develop postoperative reflux. Methods: A single-institution retrospective review of all patients who underwent a VSG with a HHR between 2014 and 2021 was conducted. The primary outcome was postoperative reflux symptoms defined by diagnosis in the medical record, utilization of anti-reflux medications, and GERD health-related quality of life (GERD-HRQL) scores obtained via patient surveys. Results: There were 190 patients included with 80 patients (42.1%) undergoing PM and 110 (57.9%) undergoing FM. Rates of preoperative reflux were similar between the two groups (47.5% vs. 51.8%; p = 0.55). During the GERD-HRQL survey, there were 114 patients (60.0%) contacted with a participation rate of 91.2% (104 patients). Patients with preoperative reflux who underwent PM were found to have a higher rate of reported postoperative reflux (90.0% vs. 62.5%; p = 0.03) and higher GERD-HRQL scores (16.40 ± 9.95 vs. 10.84 ± 9.01; p = 0.04). Patients without preoperative reflux did not have a significant difference in reported reflux (55.0% vs. 51.7%; p = 0.82) or GERD-HRQL scores (12.35 ± 14.14 vs. 9.93 ± 9.46; p = 0.25). Conclusion: Our study found that postoperative GERD was higher in patients with preexisting reflux who underwent partial esophageal mobilization during concurrent hiatal hernia repair with vertical sleeve gastrectomy. In patients without preoperative GERD, our data suggest that postoperative reflux symptoms are not dependent on the extent of esophageal mobilization during hiatal hernia repair with vertical sleeve gastrectomy.

Background: The opioid crisis caused a huge health concern in the United States. Despite this, few studies have examined the influence of opioid-related disorders (OD) on outcomes after bariatric surgery. The major goal of this study is to determine the impact of OD on in-hospital outcomes for patients undergoing bariatric surgery. Method: The National Inpatient Sample (NIS) database from 2016 to 2020 was used to evaluate patients with OD who underwent bariatric operations including sleeve gastrectomy, Roux-en-Y gastric bypass, and biliopancreatic diversion with duodenal switch. The non-OD comparison group was created using a propensity score match (1:1). Weighted analysis was carried out utilizing NIS-provided weights. The odds ratios were obtained using multivariate logistic regression. Results: A total of 159,455 patients who underwent bariatric surgery were evaluated. Propensity score matching and weighted analysis were used to compare 11,025 in the OD group and 11,025 in the non-OD group. OD was an independent predictor for postoperative complications (odds ratio: 1.29, 95% confidence interval: 1.19–1.39, p < 0.001). Among complications, OD was a predictor for bleeding complications, postoperative nausea and vomiting, anastomotic leak, and mechanical ventilation. In addition, the OD group experienced significantly longer lengths of stay (LOS) and a higher total hospital charges. Conclusion: In patients undergoing bariatric surgery, OD is associated with a significantly higher risk of postoperative complications, as well as increased LOS and total hospital charges. These patients may benefit from further preoperative optimization, including decreasing the opioid dose and closer postoperative monitoring. [ABSTRACT FROM AUTHOR]

Background: The Society of American Gastrointestinal and Endoscopic Surgeons (SAGES) Masters Program includes eight distinct clinical pathways. The Bariatric Surgery Pathway focuses on three anchoring procedures, including the laparoscopic sleeve gastrectomy (LSG) which is the most commonly performed bariatric procedure in the United States. In this article, we present and discuss the top 10 seminal articles regarding the LSG. Methods: The literature was systematically searched to identify the most cited papers on LSG. The SAGES Metabolic and Bariatric Surgery committee reviewed the most cited article list, and using expert consensus elected the seminal articles deemed most pertinent to LSG. These articles were reviewed in detail by committee members and are presented here. Results: The top 10 most cited sentinel papers on LSG focus on operative safety, outcomes, surgical technique, and physiologic changes after the procedure. A summary of each paper is presented, including expert appraisal and commentary. Conclusions: The seminal articles presented support the widespread acceptance and use of the LSG by bolstering the understanding of its mechanism of action and by demonstrating its safety and excellent patient outcomes. All bariatric surgeons should be familiar with these 10 landmark articles. [ABSTRACT FROM AUTHOR]
