Background: In the last 10 years, severe obesity and the associated metabolic syndrome have reached pandemic proportions and consequently have significantly increased the prevalence of related co-morbidities such as chronic kidney disease (CKD). One in 7 people in the United States have CKD, and 90% of those are not aware of it., Objectives: Following sleeve gastrectomy (SG) in patients with severe obesity and baseline CKD stage ≥2, to determine improvement of glomerular function and analyze the relationship between kidney function and weight loss., Setting: US Hospital, Academic Institution., Methods: We retrospectively reviewed the charts of all patients who underwent SG at our institution from 2010 to 2019. Kidney function assessment using the Chronic Kidney Disease Epidemiology Collaboration Study (CKD-EPI) equation and classification was carried out preoperatively and postoperatively at 12-months follow-up. Propensity score matching (1:1 ratio) was used to balance the distribution of covariates between patients with a baseline estimated glomerular filtration rate (eGFR) <90 mL/min/1.73 m 2 and patients with normal kidney function., Results: We calculated the eGFR of 1330 bariatric patients who underwent SG. Of these patients, 18.79% (n = 250) met the criteria for CKD-EPI eGFR calculation preoperatively and at 12-months follow-up after SG. From the 250 patients included in the analysis, 42% (n = 105) were classified as CKD stage ≥2. When comparing the baseline preoperative eGFR at 12-months follow-up after SG, we observed an improvement of 8.26 ± 11.89 mL/min/1.73 m 2 in CKD stage ≥2 (eGFR <90 mL/min/1.73 m 2 ) as compared with 1.98 ± 10.25 mL/min/1.73 m 2 in patients with eGFR >90 mL/min/1.73 m 2 (P < .001)., Conclusion: There is short-term improvement of the eGFR in patients with severe obesity following SG. This improvement is significant in CKD stages ≥2 and seems unrelated to weight loss., (Copyright © 2022 American Society for Bariatric Surgery. Published by Elsevier Inc. All rights reserved.)

Background: Laparoscopic sleeve gastrectomy (SG) has been proven safe and effective in achieving weight loss. However, the distance from the pylorus where resection should begin has been debated., Objectives: To compare the clinical outcomes of laparoscopic SG with antrum resection (AR) versus preservation (AP) for bariatric purposes by conducting a meta-analysis of randomized controlled trials (RCT)., Setting: Academic hospital, United States., Methods: PubMed and Cochrane Library were queried for RCTs from establishment to August 2020. The following key search terms were used: "sleeve gastrectomy" AND ("antrectomy" OR "antrum") AND ("randomized" OR "random"). The following data were extracted: author, publication year, country, sample size, follow-up duration, and clinical outcomes, including weight-related: excess weight loss (EWL), total weight loss (TWL), body mass index (BMI), operation time, length of hospital stay, complication rates, and resolution of obesity-related comorbidities., Results: A total of 9 unique RCTs including 492 AR and 385 AP patients were screened and included in the final quantitative analysis. Patients who underwent SG with AR showed higher EWL and TWL at 6 months (EWL: P < .001; TWL: P = .006), and 1 year (EWL: P = .013; P < .001) postoperatively. The BMI was also lower in the AR group 3 months (P = .013) and 6 months (P = .003) postoperatively. However, the EWL and BMI at 2 years were comparable between both groups (P = .222 and P = .908, respectively). No statistical significance was observed in terms of operating time, staple line disruption, bleeding, complications with a Clavien-Dindo Grade >III, resolution of comorbidities (hypertension, diabetes, hyperlipidemia, arthritis/back pain), and de novo gastroesophageal reflux disease (P > .05). AP was associated with a slightly shorter postoperative hospital stay (4.0 versus 3.1 days, P = .039)., Conclusion: Laparoscopic SG with AR is associated with superior weight loss in the short-term compared with AP. However, mid-term follow-up beyond 1 year showed no significant differences in BMI or incidence of de novo gastroesophageal reflux disease., (Copyright © 2021 American Society for Bariatric Surgery.

Purpose The aim of this study is to describe the safety and effectiveness of laparoscopic ventral hernia repair with intraperitoneal fascial closure using a barbed suture prior to mesh placement. Materials and methods Patients who underwent laparoscopic ventral hernia repair were included in this retrospective review. Patients were divided into two groups. In the first group, primary fascial closure was performed with a 2-polypropylene non-absorbable unidirectional barbed suture followed by fixation of the intraperitoneal mesh. In the second group, the mesh was fixed intraperitoneally using tacks without closing the fascial defect. Results A total of 148 patients who underwent laparoscopic primary ventral hernia repair were included. A total of 72 (48.6%) patients were included in the barbed suture with mesh group and 76 (51.4%) patients in the mesh-only group. The mean fascial defect size was 25 cm 2 in the first group and 64 cm 2  in the second group. The median suturing time for fascial closure was 15 minutes. The average surgery time was 98 minutes in the first group and 96 minutes in the second group. The mean follow-up period was 80 days for Group 1 and 135 days for Group 2. No hernia recurrence or mortality occurred in this study. Conclusion The barbed suture closure technique is a fast, safe, and effective technique for fascial closure during laparoscopic ventral hernia repair in combination with mesh placement. Further evidence to support these findings and longer follow-up periods are warranted to evaluate long-term outcomes., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2022, Montorfano et al.)

Background: In the past five 5 years our team has studied the effects of bariatric surgery on chronic kidney disease (CKD) at our institution., Objectives: The objective of this study was to assess the impact of bariatric surgery (BaS) on the prevalence and likelihood of CKD and end-stage renal disease (ESRD) nationwide., Setting: Academic hospital, United States., Methods: We conducted a retrospective analysis of the U.S. National Inpatient Sample (NIS) database for the years 2010-2015 and compared. Univariate and multivariable analysis were performed to assess the impact of BaS on the point prevalence and the probability of CKD and ESRD. Similarly, a multivariable logistic regression was conducted to measure the impact of the most important risk factors for CKD exclusively in a severely obese population., Results: Data on 296,041 BaS cases and 2,004,804 severely obese controls was extracted from the NIS database and relative to controls, all baseline CKD risk factors were less common among bariatric surgery cases. Nonetheless, even after adjusting for all CKD risk factors, controls exhibited marked increases in the odds of CKD-stage III (odds ratio [OR] 3.10 [3.05-3.14], P < .0001) and modes increase for ESRD (OR 1.13 [1.09-1.18], P < .0001). Overall, even after adjusting for risk factors we observed that the rate of CKD is significantly higher in the control group, 12% when compared with 5.3% in the bariatric surgery group (P < .0001)., Conclusion: In this retrospective, case control study of a large, representative national sample of patients with severe obesity, BaS was found to be associated with significantly reduced point-prevalence and likelihood for CKD when adjusted for baseline CKD risk factors as compared with patients with obesity who did not undergo BaS. Overall, BaS resulted in a reduced rate and a moderate decrease in the likelihood of ESRD., (Copyright © 2021 American Society for Bariatric Surgery. Published by Elsevier Inc. All rights reserved.)

Background: Obesity is considered a major cardiovascular risk factor. The excess of pericardial fat (PF) in patients with obesity has been associated with a variety of electrocardiographic alterations. In previous studies, we demonstrated that rapid weight loss and bariatric interventions result in decreased PF., Objectives: The aim of this study is to report the changes in PF after bariatric surgery and its effect on ventricular conduction., Setting: US hospital, academic institution., Methods: A linear measurement of PF thickness on computed tomography scans was obtained for 81 patients, as well as a retrospective review of electrocardiographic changes before and after bariatric surgery. We compared the changes in PF thickness and electrocardiographic components before and after procedures. Common demographics and co-morbidities were collected along with lipid profiles preoperative and postoperative., Results: A total of 81 patients had electrocardiograms done before and 1 year after bariatric surgery. Females comprised 67.9% (n = 55), and the average age for our population was 55.07 ± 14.17 years. Pericardial fat thickness before surgery was 5.6 ± 1.84 and 4.5 ± 1.62 mm after surgery (P = .0001). Ventricular conduction (QT and QT corrected [QTc] intervals) showed a significant improvement from 438.7 + 29 before to 426.8 + 25.3 after bariatric surgery (P = .006). We found a statistically significant association between the decrease in PF and the decrease in QTc intervals (P = .002)., Conclusion: Obesity is a risk factor for arrhythmias and sudden cardiac death. Bariatric surgery and its effect on PF produce an improvement in ventricular conduction, which may reduce the ventricular electrical instability in patients with obesity., (Copyright © 2021 American Society for Bariatric Surgery.

Background: Considerable evidence documents the effectiveness and efficacy of bariatric surgery (BaS) in reducing the prevalence and severity of obesity-related co-morbidities. Diastolic heart failure (DHF) is a condition with considerable morbidity and mortality, yet recalcitrant to medical therapy., Objective: Our objectives were to assess whether BaS is associated with a decrease in hospital admissions for DHF and determine its impact upon DHF hospital admissions among patients with hypertension (HTN) and coronary artery disease (CAD)., Setting: Academic institution., Methods: Data on 296 041 BaS cases and 2 004 804 controls with severe obesity were extracted from the US National Inpatient Sample database for the years 2010 to 2015 and compared. Univariate and multivariable analysis were performed to assess the impact of pre-2010 BaS on the rate of hospital admissions for DHF, adjusting for demographics, co-morbidities, and other risk factors associated with cardiovascular disease (CVD)., Results: Relative to controls, all baseline CVD risk factors were less common among BaS cases. Nonetheless, even after adjusting for all CVD risk factors, controls exhibited marked increases in the odds of DHF overall (odds ratio = 2.80; 95% confidence interval = 2.52-3.10). Controls with HTN and CAD demonstrated an almost 3-fold increase in odds of DHF admissions. Similarly, controls with no HTN demonstrated a 5-fold increase in odds of admissions for DHF when compared to the surgical group., Conclusions: In this retrospective, case control study of a large, representative national sample of patients with severely obesity, BaS was found to be associated with significantly reduced hospitalizations for DHF when adjusted for baseline CVD risk factors. It also reduced DHF incidence in high-risk patients with HTN and CAD., (Copyright © 2021 American Society for Bariatric Surgery. Published by Elsevier Inc. All rights reserved.)

Background: The incidence of obesity has been steadily increasing, especially in developed countries. Also, obesity is considered one of the modifiable risk factors of kidney cancer., Objectives: This study aims to determine the impact of bariatric surgery-induced weight loss on the prevention of kidney cancer., Setting: Academic Hospital, United States., Methods: The National (Nationwide) Inpatient Sample (NIS) was queried for the period 2010 to 2015 for first-time kidney cancer-related hospitalization, used as a proxy for cancer incidence, in patients with a history of bariatric surgery (cases) and patients with obesity but no history of bariatric surgery (controls). Patients with a previous diagnosis of cancer were excluded from the analysis. In order to identify comparable patients, all controls had to have a body mass index ≥35 kg/m 2 , as per the existing qualification criteria for bariatric surgery. The International Classification of Diseases-9 codes (ICD-9) was used to identify admissions for kidney cancer. A univariate analysis was conducted to compare demographics and co-morbidities between groups. A multivariate logistic regression model was performed to assess differences between surgical and control groups and adjust for independent variables such as smoking history and family history of malignancy. All percentages and means (with confidence intervals [CIs]) were weighted., Results: A total of 2,300,845 were included in the analysis, of which 2,004,804 controls-subjects, with a mean age of 54.4 ± .05 years, and 296,041 treatment-subjects, with a mean age of 51.9 ± .05 years. Demographics and co-morbidities, such as tobacco use, diabetes, and hypertension, were also measured. Patients with a history of bariatric surgery were significantly less likely to experience renal cancer than patients without a history of bariatric surgery, with 5935 cases in the control group and 684 in the case group (P < .0001). After a multivariate logistic regression was performed, the OR was 1.10 (95% CI: 1.02-1.22, P < .0224)., Conclusion: Our finding suggests that bariatric surgery-induced weight loss could significantly prevent first-time kidney cancer-related hospitalizations in patients with obesity. Prospective studies are needed to confirm our findings., (Copyright © 2021 American Society for Bariatric Surgery. Published by Elsevier Inc. All rights reserved.)

Background: Obesity independently increases the risk of hospitalization due to viral respiratory infections, including influenza virus and, more recently, severe acute respiratory syndrome coronavirus 2. As an independent risk factor, obesity impairs the immune response to viral infections and decreases the effectiveness of immunizations., Objectives: Using influenza as a proxy, we aimed to determine the impact of bariatric surgery (BaS) on the risk of hospitalization due to viral respiratory infections., Setting: Academic hospital, United States., Methods: National (Nationwide) Inpatient Sample data collected from 2010 to 2015 were examined. Patients were classified as treatment and control groups. Treatment subjects were defined as patients with a history of BaS and control subjects as patients with a body mass index ≥35 kg/m 2 and without a history of BaS. Any hospitalization with influenza as a primary diagnosis was identified. Univariate analysis and multivariate regression models were performed to assess the differences between groups., Results: A total of 2,300,845 subjects were reviewed, of which 2,004,804 were control subjects and 296,041 were treated patients. Univariate analysis showed that the hospitalization rate in the treatment group was significantly lower than in the control group (.007% versus .019%, P < .0001), which was confirmed after adjusting for covariables (control versus treatment: odds ratio = 2.21, P = .0010)., Conclusions: BaS may decrease the risk of hospitalization due to influenza, but further prospective studies are needed to confirm these results. We also suggest that these results should be translated into the development of similar studies to determine the impact of BaS on the incidence and severity of the coronavirus disease 2019., (Copyright © 2021 American Society for Bariatric Surgery.

Background: The population undergoing bariatric surgery (BaS) has many cardiovascular risk factors that can lead to significant perioperative cardiovascular morbidity., Objectives: We aimed to examine trends in the incidence of major adverse cardiovascular and cerebrovascular events (MACCE) after BaS., Setting: Academic Hospital, United States METHODS: We performed a retrospective analysis of the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) data registry for patients aged ≥18 years undergoing laparoscopic sleeve gastrectomy (LSG) and laparoscopic Roux-en-Y gastric bypass (LRYGB) from 2015 to 2019. Data on demographics, co-morbidities, and type of procedure were collected. MACCE was defined as a composite variable including perioperative acute myocardial infarction (AMI), cardiac arrest requiring cardiopulmonary resuscitation, acute stroke, and all-cause mortality. We utilized the Cochrane-Armitage and Jonckheere-Terpstra tests to assess for significant trend changes throughout the years., Results: A total of 752,722 patients were included in our analysis (LSG = 73.2%, LRYGB = 26.8%). Postoperative MACCE occurred in 1058 patients (.14%), and was more frequent in patients undergoing LRYGB (.20%). The frequency of MACCE declined from .17% to .14% (P = .053), driven by a decline in the frequency of AMI (.04% to .02%, P = .002), cardiac arrest (.05% to .04%, P = .897), and all-cause death (.11% to .08%, P = .040), but with an increase in perioperative stroke (.01% to .02%, P = .057)., Conclusion: The overall risk of MACCE after BaS is .14% and has been declining in the last 5 years. This trend is likely multifactorial and further analysis is necessary to provide a detailed explanation., (Copyright © 2021 American Society for Bariatric Surgery. Published by Elsevier Inc.

Background: Common bile duct injuries (BDI) during laparoscopic cholecystectomy (LC) continue to be the source of morbidity and mortality. The reason for BDI is mostly related to the misidentification of the extrahepatic bile duct structures and the anatomic variability. Near-infrared fluorescent cholangiography (NIFC) has proven to enhance visualization of extrahepatic biliary structures during LCs. The purpose of this study was to describe the most important steps in the performance of NIFC., Methods: In accordance to the most current surgical practice of LC at our institution, a consensus was achieved on the most relevant steps to be followed when utilizing NIFC. Dose of indocyanine green (ICG), time of administration, and identification of critical structures were previously determined based on prospective and randomized controlled studies performed at CCF., Results: The ten steps identified as critical when performing NIFC during LC are preoperative administration of ICG, exposure of the hepatoduodenal ligament, initial anatomical evaluation, identification of the cystic duct and common bile duct junction, the cystic duct and its junction to the gallbladder, the CHD, the common bile duct, accessory ducts, cystic artery and, time-out and identification of Calot's triangle, and evaluation of the liver bed., Conclusions: Routine use of NIFC is a useful diagnostic tool to better visualize the extrahepatic biliary structures during LC. The implementation of specific standardized steps might provide the surgeon with a better algorithm to use this technology and consequently reduce the incidence of BDI., (© 2021.

Background and Objective: Postoperative urinary retention (POUR) is a common adverse event after inguinal hernia repair (IHR), with an incidence of up to 22.2%. The aim of this study is to determine if pre-operative transverse abdominis plane (TAP) block increases the incidence of POUR., Methods: A retrospective review was performed for all patients who underwent IHR (open or laparoscopic) at this institution, from January 1, 2016 to December 31, 2017. Patients were divided into two groups: Patients that had a TAP block before surgery (group 1) and patients with no TAP block (group 2). Common demographics and comorbidities were collected along with postoperative outcomes and POUR incidence rates for every group to determine procedural influence., Results: From 276 patients reviewed, 28.2% (N = 78) underwent TAP block before surgery. The patient cohort mean age was 61.1 ± 14.4 years. Most the interventions were laparoscopic (81.2%) and an overall POUR incidence rate of 7.6% (N = 21) was observed. Comparatively, common demographics and comorbidities were statistically similar for both groups, with the exception of type 2 diabetes mellitus ( p  =   0.049). Individually, group 1 and 2 presented POUR incidence rates of 14.1% and 5.05%, respectively. While intraoperative fluid administration, early readmission rate, and length were similar in both groups, there was a significant difference in POUR incidence rates ( p  =   0.01)., Conclusion: Patients undergoing TAP block during IHR might have an increased risk of developing POUR. Further larger, prospective, and randomized controlled studies are necessary to better assess these findings., Competing Interests: Conflict of interests: none., (© 2021 by SLS, Society of Laparoscopic & Robotic Surgeons.)

Background: Aortic dissection (AD) is an uncommon but life-threatening condition associated with high morbidity and mortality. Hypertension (HTN) and hyperlipidemia (HLD) are common modifiable risk factors., Objectives: Since bariatric surgery is associated with remission of obesity-related co-morbidities, we hypothesize that surgical weight loss might be protective against this feared aortic pathology., Setting: A cross-sectional analysis was performed using the National Inpatient Sample database from 2010 to 2015., Methods: The treatment group included bariatric patients and the control group patients with obesity (body mass index [BMI] ≥ 35kg/m 2 ) without previous bariatric surgery. Analyzed covariates included demographics, co-morbidities, aortic diseases, and AD. A multivariate logistic regression analysis (MLRA) was performed to assess the odds of admission for AD in both groups., Results: A total of 2,300,845 patients were identified (2,004,804 controls and 296,041 cases). The mean (SEM) age was 54.4 (.05) versus 51.9 (.05) years, for the control and treatment groups, respectively (P < .0001). Bariatric patients posed a significantly lower prevalence of type 2 diabetes (T2D), HTN, HLD, aortic aneurysm, and bicuspid aortic valve (P < .0001) than control subjects. In the control group, 1411 individuals (.070%) had AD, whereas only 94 patients (.032%) in the bariatric surgery group had such diagnosis (P < .0001). The MLRA showed that non-bariatric obese patients had a significantly higher likelihood of suffering from AD (OR = 1.8 [95%CI 1.44-2.29] P < .0001). Considering different age groups, bariatric surgery was found to be less associated with admission for AD for individuals below and above 40 years of age (OR = 2.95 [95%CI 1.09-7.99] P = .0345) and (OR = 1.75 [95%CI 1.38-2.22] P < .0001), respectively., Conclusions: Bariatric surgery could be a protective factor against aortic dissection and should be considered in patients with obesity and risk factors for this cardiovascular complication., (Copyright © 2021 American Society for Bariatric Surgery.

Background: Obesity is a major risk factor for the development of metabolic syndrome, coronary artery disease, and heart failure (HF). Rapid weight loss following bariatric surgery can significantly improve outcomes for patients with these diseases., Objectives: To assess whether bariatric surgery improves ventricular ejection fraction in patients with obesity who have heart failure., Setting: Private practice, United States., Methods: We conducted a retrospective review of echocardiographic changes in systolic functions in patients with obesity that underwent bariatric surgery at our institution. Patients were divided into 2 groups, those (1) without known preoperative HF and (2) with preoperative HF. We compared the left ventricular ejection fraction (LVEF) before and after bariatric surgery in both groups. Common demographics and co-morbidities were also analyzed., Results: A total of 68 patients were included in the analysis: 49 patients in group 1 and 19 in group 2. In group 1, 59.2% (n = 29) of patients were female, versus 57.9% (n = 11) in group 2. The excess body mass index lost at 12 months was 52.06 ± 23.18% for group 1 versus 67.12 ± 19.27% for group 2 (P = .0001). Patients with heart failure showed a significant improvement in LVEF, from 38.79 ± 13.26% before to 48.47 ± 14.57% after bariatric surgery (P = .039). Systolic function in patients from group 1 showed no significant changes (59.90 ± 6.37 mmHg) before and (59.88 ± 7.85 mmHg) after surgery (P = .98)., Conclusion: Rapid weight loss after bariatric surgery is associated with a considerable increase in LVEF and a significant improvement of systolic function., (Copyright © 2021 American Society for Bariatric Surgery.

Background: Bariatric surgery in the elderly population has been reported as feasible and safe. Sleeve gastrectomy (SG) seems to have fewer complications than Roux-en-Y gastric bypass (RYGB) even in the 65 years of age population. We analyzed the difference in weight loss between SG and RYGB in patients age 65 years., Objectives: To analyze and compare outcomes between SG and RYGB in patients 65 years of age and older., Setting: Academic hospital, United States., Methods: After internal review board approval, we retrospectively reviewed 2486 patients who underwent either SG or RYGB between 2005 and 2018 at our institution. Basic demographics, preoperative body mass index (BMI), and co-morbidities were described. We identified all patients age ≥65 years and subsequently divided them into 2 groups based on type of bariatric procedure performed. Analysis and comparison of outcomes between these groups were completed. Postoperative BMI was reviewed at 6, 12, and 24 months and percent excess BMI loss (%EBMIL, as defined by the ASMBS clinical committee) was calculated accordingly. The t test and χ 2 analysis were performed for nominal and categorical variables, respectively., Results: From 2486 patients reviewed, 22.7% (n = 565) were aged ≥65 years. From these, 43.1% (n = 244) underwent SG and 56.8% (n = 321) underwent RYGB. White and female patients were predominant in both groups. Mean age was similar for both populations (SG: 71.1 ± 4.0, RYGB: 71.7 ± 4.5; P = .12). Pre-procedure mean BMI for both groups was close in value, but the difference was statistically significant (40.5 ± 5.5 for SG versus 43.7 ± 7.2 for RYGB; P < .0001). Postoperative follow-up rates were similar in both groups at 12 and 24 months (SG: 51.2% and 31.6%; RYGB: 48.3% and 34.3%; P = .49 and P = .5). The %EBMIL at 6, 12, and 24 months was higher for the RYGB group than the SG group (59.3 ± 27.9, 72.1 ± 29.5, 77.4 ± 26.1 versus 50.2 ± 21.9, 55.2 ± 25.6, 43.9 ± 32.2; P < .01, P < .01, and P < .01, respectively). Complication rates were significantly higher in RYGB versus SG (27.7% versus 9.4%; P < .01). We observed significantly higher anastomotic ulcer and stricture rates for RYGB versus SG (7.2% and 5.9 versus 0% and 0%; P < .01 and P < .01, respectively). RYGB had a higher rate for gastrointestinal obstruction requiring intervention (2.2% versus .4%; P = .07). A similar de novo gastroesophageal reflux disease rate was noted in both procedures (3.7% versus 3.7%; P = .98). No leaks were reported in either group., Conclusions: Both SG and RYGB are effective weight loss procedures for patients aged ≥65 years. RYGB seems to have higher %EBMIL at 1 and 2 years; however, when compared with SG, complication rates appear to be almost 3 times higher., (Copyright © 2021 American Society for Bariatric Surgery.

Background: Feeding jejunostomy is an alternative route of enteral nutrition in patients undergoing major gastrointestinal operations when a feeding gastrostomy is not suitable., Methods: A single institution review of patients who underwent open or laparoscopic jejunostomy tube (JT) placement between 2009 and 2019 was performed. Data collected included demographics, preoperative serum albumin, surgery indication, concomitancy of procedure, size of JT tube and time to its removal. JT complications were analyzed in the early postoperative period (< 30 days) and in a long-term follow-up (> 30 days). The Chi-square test was used to compare rates of complications according to tube size., Results: Seventy-three patients underwent JT placement, and gastroesophageal cancer (n = 48, 65.7%) was the most common indication. The JT was most frequently placed concomitantly (n = 56, 76.7%) to the primary operation and through a laparoscopic approach (n = 66, 90.4%). A total of 14 patients (19.1%) had early complications and 15 had late complications (20.5%). The reasons for early complications were clogged JT (n = 8, 10.9%), JT dislodgement (n = 3, 4.1%), leakage (n = 2, 2.7%), small bowel obstruction adjacent to the site of the jejunostomy tube (n = 2, 2.7%), JT site infection (n = 1, 1.3%), and intraperitoneal JT displacement (n = 1, 1.3%). The reasons for late complications were clogged JT (n = 6, 8.2%), JT dislodgement (n = 6, 8.2%), JT site infection (n = 3, 4.1%), and JT leakage (n = 1, 1.3%). There was no procedure-related mortality in this series. However, 12 patients (16.4%) died due to their baseline disease. The mean time to tube removal was 83.4 ± 93.6 days. The most frequently used JT size was 14 French (n = 39, 53.4%) but in nine patients the tube size was not reported. No statistical significance (p = 0.75) was found when comparing the two most commonly used sizes to rates of complications., Conclusion: The rate of JT complications in our study is comparable to other published reports in literature. As an alternative route for nutritional status optimization, the procedure appears to be safe despite the number of complications.

Background: Obesity is a well-known risk factor for heart disease, resulting in a broad spectrum of cardiovascular changes. Left ventricular mass (LVM) and contractility are recognized markers of cardiac function., Objectives: To determine the changes of LVM and contractility after bariatric surgery (BaS)., Setting: University hospital, United States METHODS: To determine the cardiac changes in ventricular mass, ventricular contractility, and left ventricular shortening fraction (LVSF), we retrospectively reviewed the 2-dimensional echocardiographic parameters of patients with obesity who underwent BaS at our institution. We compared these results before and after BaS., Results: A total of 40 patients met the inclusion criteria. The majority were females (57.5%; n = 23), with an average age of 63.5 ± 12.1. The excess body mass index (BMI) lost at 12 months was 48.9 ± 28.9%. The percent total weight loss after BaS was 16.46 ± 9.9%. The left ventricular mass was 234.9 ± 88.1 grams before and 181.5 ± 52.7 grams after BaS (P = .002). The LVM index was 101.3 ± 38.3 g/m 2 before versus 86.7 ± 26.6 g/m 2 after BaS (P = .005). The LVSF was 31% ± 8.8% before and 36.3% ± 8.2% after BaS (P = .007). We found a good correlation between the decrease in LVM index and the BMI after BaS (P = .03)., Conclusion: Rapid weight loss results in a decrease of the LVM index, as well as improvement in the left ventricular muscle contractility. Our results suggest that there is left ventricular remodeling and an improvement of heart dynamics following bariatric surgery. Further studies are needed to better assess these findings., (Copyright © 2021 American Society for Bariatric Surgery. Published by Elsevier Inc. All rights reserved.)

Background: Body fat distribution is highly associated with metabolic disturbances. Skeletal muscle plays an important role in glucose metabolism, as it serves as an important organ for glucose storage in the form of glycogen. In fact, low muscle mass has been associated with metabolic syndrome, type 2 diabetes (T2D), systemic inflammation, and decreased survival., Objectives: To compare the relationship between visceral abdominal fat (VAF) and fat free mass (FFM) with the improved glucose metabolism after bariatric surgery., Setting: University hospital, United States., Methods: A retrospective review was performed of all patients who underwent bariatric surgery between 2011 and 2017 at a university hospital in the United States. In severely obese patients with T2D, we measured the VAF via abdominal computed tomography scan and we calculated the FFM preoperatively and at a 12-month follow-up. Data collected included baseline demographic characteristics and perioperative parameters, such as treatment for hypertension (HTN) and T2D, body mass index (BMI), glycated hemoglobin (HbA1C), glucose, and lipid profile., Results: A total of 25 patients met the inclusion criteria. The average age was 52.5 ± 11.6 years. The initial BMI was 41.41 ± 5.7 kg/m 2 and the postoperative BMI was 31.7 ± 6.9 kg/m 2 (P < .0001). The preoperative VAF volume was 184.6 ± 90.2 cm 3 and the postoperative VAF volume was 93.8 ± 46.8 cm 3 at the 12-month follow-up (P < .0001). The preoperative FFM was 55.2 ± 11.4 kg and the postoperative FFM was 49.1 ± 12 kg (P < .072). The preoperative HbA1C was 5.8% ± .9%, which decreased postoperatively to 5.3% ± .4% at the 12-month follow-up (P < .013)., Conclusion: Bariatric surgery has been demonstrated to be an effective treatment modality for severe obesity and T2D. Our results suggest that at 12 months, there is a reduction in VAF and HbA1C without a significant loss of FFM. Further prospective studies are needed to better understand these findings., (Copyright © 2021 American Society for Bariatric Surgery. Published by Elsevier Inc. All rights reserved.)

With the exponential increase of worldwide obesity, the number of bariatric surgery (BaS) procedures have equally risen. The surgical management of obesity has been widely established as the standard of care for sustained weight reduction, resolution, and improvement of associated comorbidities. However, BaS itself can have postoperative deleterious effects, including de novo gastroesophageal reflux disease (GERD) and upper gastrointestinal motility disorders. The modified anatomy resulting from BaS, due to either a restrictive or hypoabsorptive component, gives this disorder a multifactorial etiology. The overall management of de novo GERD should focus on three primordial approaches: Non-surgical, endoluminal, and surgical. Even in the absence of de novo GERD following primary or secondary BaS, said disorder should be closely monitored and therapy should be catered in a case-by-case approach. Consequently, treatment strategies have been developed on this principle as to adequately resolve de novo GERD. Despite the presence of multiple and suitable treatment modalities, the operating surgeon should perform them in the best interest of the patient. Short-, medium-, and long-term outcomes should be taken into consideration prior to proceed with any type of preferred management option.

Background: Gastroparesis (GPS) is a rare disease with multiple etiologies that results in delayed gastric emptying. Diagnosis of GPS can be challenging due to its rather complex clinical presentation. Pharmacologic refractory cases require surgical interventions, all of which have yet to be standardized and characterized., Objectives: We present a review of the literature and provide an update of current therapies for patients with GPS., Setting: Department of General Surgery, Academic Hospital, United States., Methods: We conducted a comprehensive search in PubMed, Google Scholar, and Embase of English-written articles published in the last 38 years, with an advance title search of "gastroparesis management." Other keywords included: "surgical management" and "refractory gastroparesis." Further references were obtained through cross-reference., Results: A total of 12,250 articles were selected after eliminating duplicates. Following thorough screening of selection criteria, 68 full-text articles were included for review., Conclusion: GPS is a challenging disease to manage. Nutritional support must remain the primary approach, followed by either medical or surgical treatment modalities if necessary. In patients with refractory gastroparesis, adjunctive therapies have been proposed as promising long-term options., (Copyright © 2020 American Society for Bariatric Surgery.

Background: Sleeve gastrectomy (SG) has become the most prevalent bariatric-metabolic surgical approach in the United States. Its popularity among surgeons and patients is mainly due to a better safety profile and less overall morbidity, with broad benefits from a systemic and metabolic perspective., Objective: Comprehensively describe the short-term multiorgan metabolic effects of rapid weight loss after SG., Setting: Academic hospital, United States., Methods: We retrospectively reviewed the charts of patients that underwent SG at our institution between 2012 and 2016. We analyzed the required variables to calculate multiple risk scores, such as cardiovascular, hypertension, and diabetes risk scores. Furthermore, the renal and hepatic functions and the metabolic and hematologic profiles were assessed at 12 months of follow-up., Results: A total of 1002 patients were included in the analysis. The percentage of excess body mass index loss was, on average, 65% at 12 months of follow-up. We observed a positive cardio-renal-hepatic improvement, demonstrated by a substantial reduction of the 10-year cardiovascular risk. We noticed an improvement of renal function, which was more significant in chronic kidney disease (stage ≥2), and a significant improvement on liver function tests (measured by decreased aspartate aminotransferase and alanine transaminase) at 12 months of follow-up. Our data also show a positive impact on decreasing the risk of developing hypertension and type 2 diabetes. There was a positive impact on the lipid profile, with the exception of low-density lipoprotein., Conclusion: There are significant short-term benefits on multiorgan metabolic parameters after rapid weight loss in severely obese patients undergoing sleeve gastrectomy., (Copyright © 2020 American Society for Bariatric Surgery.

Background: Pericardial fat has a local atherosclerotic effect and is associated with both metabolic syndrome (MetS) and coronary artery disease (CAD)., Objectives: The aim of this study is to report changes in pericardial fat thickness (PFT) after bariatric surgery, and to investigate its significance on the risk of developing coronary artery disease (CAD)., Setting: Academic institution., Methods: We retrospectively measured the linear pericardial thickness from patients' computed tomography (CT) scans within 5 years preoperatively and compared to any available CT scan within 5 years postoperatively. The PFT was measured at the right ventricular wall, perpendicular to the myocardium, at the level of the sternum. The risk of developing CAD was estimated by calculating the Framingham risk score (FRS). We divided the patients into 2 groups: laparoscopic sleeve gastrectomy (SG, Group 1), and laparoscopic gastric Roux-en-Y gastric bypass (LRYGB, Group 2). Common demographic characteristics and co-morbidities were collected along with the preoperative and postoperative lipid profiles., Results: A total of 113 patients met the inclusion criteria, with 64 (56.6%) patients in group 1 and 49 (43.3%) patients in group 2. Group 1 consisted of 83.6% (n = 53) female patients versus 75.5% (n = 37) in group 2. The percent excess body mass index loss (%EBMIL) at 12 months was 74.4 ± 35.8% for group 1 versus 67 ± 30.1% for group 2 (P = .292). Pericardial thickness before surgery was 5.6 ± 1.9 mm and 4.6 ± 1.6 mm after surgery (P = .0001). The risk of CAD in females was 9.1% before and 6.6% after surgery. We found statistically significant linear association between pericardial thickness after surgery and a lower risk of CAD (P = .001)., Conclusion: Bariatric surgery decreases the PFT lowering risk of developing CAD. Further studies may be needed to better assess these findings., (Copyright © 2020 American Society for Bariatric Surgery. Published by Elsevier Inc. All rights reserved.)

Background: Bariatric surgery (BaS) is the safest, most effective, and most durable therapy for obesity but is performed in less than 1% of the affected United States (US) population. It is challenging to determine from traditional surveys if this phenomenon is the result of poor access to care or lack of interest among Internet users., Objectives: The aim of this study was to use Google Trends (GT) as a tool to analyze the US general population interest in BaS., Setting: Academic Hospital, United States., Methods: GT was used to access data searched for the term bariatric surgery. The gathered information included data from 2008 through 2018 in English within the US. Search frequency, time intervals, locations, frequent topics of interest, and related searches were analyzed. GT reports search frequency on means, and a value of 100 represented peak popularity., Results: The number of Google searches related to the term bariatric surgery has gradually increased over time, from a mean of 67% in 2008 to a 94% interest in 2017. Regarding interest by subregion in 2017, the state of Michigan lead the frequency of searches, followed by Indiana, Delaware, West Virginia, and Tennessee. Top searched terms by frequency were the following: patient eligibility for BaS, what is BaS, what are the complications of BaS, financial costs of BaS, and what insurance companies cover BaS. It appears that traditional Web sites only address a few., Conclusions: GT complements the understanding of interest in BaS. Using these trends can improve an Internet user's education, and tailor specific official Web sites for the public's general interest., (Copyright © 2020 American Society for Bariatric Surgery.

Background: According to the U.S. Centers for Disease Control, cancers linked to overweight or obesity accounted for roughly 40% of all U.S. malignancies in 2014., Objectives: The primary aim of this epidemiologic study was to assess whether bariatric surgery might have any preventative role against obesity-linked cancers among individuals with obesity., Setting: Hospitals across the United States participating in the National Inpatient Sample database, created, updated, and monitored by the U.S. Healthcare Cost and Utilization Project., Methods: National Inpatient Sample data collected from 2010 to 2014 were examined to identify any difference in the number of first cancer-related hospitalizations, as a proxy for cancer incidence, between patients with a history of prior bariatric surgery (cases) and those without (controls). Patients with any prior cancer diagnosis were excluded. To match the body mass index ≥35 kg/m 2 generally required for bariatric surgery, all controls had to have a body mass index ≥35 kg/m 2 . International Classification of Diseases-9 codes were employed to identify admissions for 13 obesity-linked cancers. Multivariate logistic regression analysis was performed to identify any case-control differences, after matching for all baseline demographic, co-morbidity, and cancer risk-factor variables. All percentages and means (with confidence intervals) were weighted, per Healthcare Cost and Utilization Project guidelines., Results: Among 1,590,579 controls and 247,015 bariatric surgery cases, there were 29,822 (1.93%; 95% confidence interval 1.91-1.96) and 3540 (1.43%; 1.38-1.47) first hospitalizations for cancer (adjusted odds ratio 1.17; 1.13-1.23; P < .0001)., Conclusions: Preliminary findings from a large U.S. database suggest that bariatric surgery may reduce the incidence of cancer in patients considered at high risk because of severe obesity., (Copyright © 2020 American Society for Bariatric Surgery.

Background: The number of patients undergoing bariatric surgery with prior cardiac revascularization (CR) is rising. However, scarce data exist regarding the safety of bariatric procedures in these patients., Objectives: The aim of this study is to compare postoperative cardiovascular and noncardiovascular outcomes among patients with different CR procedures., Setting: Academic hospital, United States., Methods: We retrospectively reviewed 2884 patients undergoing bariatric surgery from 2009-2018. Patients with prior CR were included and stratified into groups: coronary artery bypass graft (CABG), percutaneous coronary intervention with stent (PCI), and CABG + PCI. We described patient demographic characteristics, co-morbidities, smoking status, history of myocardial infarction, type of bariatric surgery, number of vessels grafted/stents, time from CR to bariatric surgery, length of stay, and cardiovascular and noncardiovascular 30-day outcomes. A control group composed of patients without prior CR undergoing bariatric surgery was used to compare the rate of complications to the total patients with prior CR. For continuous and categorical variables, t test and χ 2 tests were performed, respectively., Results: We identified 76 patients with prior CR undergoing bariatric surgery. The mean patient age was 61.4 ± 7.9 years, the mean body mass index was 41.7 ± 6.5 kg/m 2 , and male sex was predominant (71.1%). Among these, 50% (n = 38) had PCI, 39.4% (n = 30) had CABG, and 10.5% (n = 8) had CABG + PCI. Early cardiovascular complications rate included ST-segment-elevation myocardial infarction (n = 2), pulmonary embolism (n = 1), supraventricular arrhythmia (n = 2), ventricular arrhythmia (n = 1), and pacemaker/defibrillator-insertion (n = 1). The overall rate of cardiovascular and noncardiovascular complications was 9.2% (n = 7) and 10.5% (n = 8) during the 30 days. Mortality rate was 0%. Comparison of rate of complications between groups did not show any statistical difference; no significant difference was found when comparing patients with prior CR to the 76 patients in the control group (P > .05)., Conclusions: Although revascularized individuals have severe co-morbidities and are high-risk patients, bariatric surgery remains safe in this population when outcomes are compared with bariatric patients without prior CR., (Copyright © 2020 American Society for Bariatric Surgery.

Background: Coronary heart disease (CHD) accounts for one third of all deaths in people older than 35 years in the United States., Objectives: The aim of this study is to determine the impact of bariatric surgery, especially laparoscopic sleeve gastrectomy, on the risk of developing CHD., Setting: Academic, University affiliated hospital., Methods: We retrospectively reviewed all patients who underwent bariatric surgery from 2010-2016. All patients between 30 and 74 years of age without a previous history of CHD were included in our study. The risk score for predicting the incidence of CHD was measured preoperatively and at 12 months of follow-up., Results: Of the 1330 patients studied, 225 patients (16.9%) had all the required variables to calculate the CHD risk score. The mean age of our population was 51.4 ± 11.3 years, mostly female (67%, n = 152) and white (58.7%, n = 132). At the preoperative setting, our patient population had a systolic blood pressure in the prehypertensive ranges, with 40% (n = 90) having type 2 diabetes and 60% (n = 134) having arterial hypertension. The preoperative CHD preoperative risk was 8.9 ± 7.7% or 8-fold higher than the ideal risk. After 12 months of follow-up, the CHD absolute risk reduction was 2.7%, and the relative risk reduction was 42.0% for female patients and 5.4% and 38.8%, respectively, for male patients. All the metabolic factors used to calculate the risk of developing CHD had a significant improvement after 12 months., Conclusions: Surgical weight loss reduces the risk of developing CHD. Further studies should assess these findings in a long-term follow-up., (Copyright © 2020 American Society for Bariatric Surgery. Published by Elsevier Inc. All rights reserved.)

Background: Despite its popularity, sleeve gastrectomy (SG) is not devoid of postoperative complications and weight regain. Some of these cases warrant conversion to Roux-en-Y gastric bypass or proximal gastrectomy with Roux-en-Y esophagojejunostomy. Complications after conversion are scarcely reported in the literature., Objectives: Report and review the outcomes of reoperation on severely obese patients with weight regain or complications after SG., Setting: Bariatric Surgery Center of Excellence; Community Hospital, United States., Methods: We retrospectively reviewed the medical records of patients converted from SG to Roux-en-Y gastric bypass/proximal gastrectomy with Roux-en-Y esophagojejunostomy at our center, from 2004 to 2018. Patients were stratified by reason for conversion. Group A included those converted for complications (leaks, strictures, or gastroesophageal reflux disease) and group B for reported weight regain. Demographic characteristics, postoperative outcomes, and complications were described., Results: From 77 conversions identified, 63.6% (n = 49) underwent primary SG at an outside hospital. We observed predominant female (68.8%; n = 53) and Caucasian (76.6%; n = 59) populations. Conversions for complications were performed in 67.5% (n = 52) and for weight regain in 32.4% (n = 25). The most common conversion indication in group A was chronic leak (29.9%; n = 23), followed by gastroesophageal reflux disease (20.8%; n = 16), and stricture (16.9%; n = 13). Overall, major complications occurred in 16.9% (n = 13) and minor complications in 19.4% (n = 15). In group A, most common major complications were anastomotic leak and organ space surgical site infection (3.9%; n = 2 each); the most common minor complication was nonperforated marginal ulcer (7.7%; n = 4). In group B, the most common major complication was perforated marginal ulcer (8%; n = 2); the most common minor complication was stricture (16%; n = 4). Group B mean preconversion body mass index was 38.4 ± 4.3 and percentage excess body mass index loss was 48 ± 33, 63 ± 45, 59 ± 63, and 73 ± 25 (12, 24, 36, ≥48 mo)., Conclusions: Our experience shows that major complications can occur in up to 17% of patients after conversion. Conversion to Roux-en-Y gastric bypass in nonresponders appears to be a safe and effective option for body mass index reduction., (Copyright © 2020 American Society for Bariatric Surgery.

Background: Arterial hypertension (HTN) is one of the most important risk factors for the development and progression of chronic kidney disease (CKD). Rapid weight loss after bariatric interventions has a positive impact on blood pressure levels of hypertensive patients. The aim of our study is to assess the prevalence of HTN in patients with CKD after bariatric surgery (BS)., Methods: We retrospectively reviewed severely obese patients who underwent BS from 2010 to 2017. We used guidelines of the American College of Cardiology to define HTN. Only patients meeting ACC criteria and the calculation of estimated glomerular filtration rate (eGFR) using CKD epidemiology collaboration study equation preoperatively and at 12-month follow-up were included in the analysis., Results: From a total of 2900 patients, 29.13% (845) met the required criteria and had variables for the calculation of eGFR recorded preoperatively. 36.92% (312) had preoperative HTN and s classified as CKD stage ≥ 2. We observed a predominantly female population 63.83% (203) with mean age of 54.10 ± 11.58. Patients preoperatively classified in CKD 2, 3a, and 3b exhibited the greatest prevalence reduction of HTN at 12-month follow-up (68.59%, n = 214 vs. 36.59%, n = 114; 16.67%, n = 52 vs. 6.41%, n = 20; 7.69%, n = 24 vs. 1.28%, n = 4; p < 0.0001). A marked improvement in CKD was also observed along with improvement in HTN. The greatest benefit corresponded to patients classified preoperatively in CKD 2, 3a and 3b. A total of n = 70 (62.5%) patients with HTN were classified as CKD 2 preoperatively compared to n = 55 (49.11%) at 12-month follow-up (p = 0.0436). Similarly, n = 22 (19.64%) patients with HTN were classified preoperatively as CKD 3a compared to n = 7 (6.25%) and n = 12 (10.71%) patients as CKD 3b compared to n = 4 (3.57%) during the same time period (p = 0.0028, p = 0.0379, respectively)., Conclusions: Rapid weight loss after BS significantly reduces prevalence of HTN in all stages of CKD at 12-month follow-up. Additionally, there was a positive impact on classification of CKD at 12-month follow-up.

Background: Risk factors for heart disease include arterial hypertension, high cholesterol, tobacco abuse, and obesity. There is a paucity of data regarding role of ethnicity in bariatric surgery (BS) outcomes. The study's aim is to determine if ethnicity plays a significant role in BS outcomes, heart age, and cardiovascular risk., Methods: We conducted a retrospective review of data collected concurrently from patients who underwent BS from 2010 to 2015. We analyzed demographics, comorbidities, heart age, and cardiovascular risk-score at surgery and 12-month follow-up. Ethnicities categorized were Caucasian and African American. Heart age was calculated using the Framingham Study Heart Age Calculator and cardiovascular risk-score using the Atherosclerotic Cardiovascular Disease Risk Calculator., Results: A total of 292 patients presented all the variables needed to calculate heart age and cardiovascular risk score. This patient population was composed of 85% Caucasians and 15% African American. Female gender represented 67% (N = 202) of patients with mean age of 52.6 ± 10.7 years. LSG was the most prevalent procedure performed in 73.2% (N = 213) of patients. Mean BMI pre-operatively versus post-operatively by ethnicity was 41.46 ± 4.66 vs 30.08 ± 4.34 Caucasians and 41.90 ± 4.69 vs 32.08 ± 4.68 African Americans. Mean heart age pre-operatively versus post-operatively by ethnicity was 71.35 ± 14.59 vs 62.45 ± 16.12 (p < 0.0001) for Caucasians and 71.38 ± 14.30 vs 65.91 ± 16.61 (p = 0.11) for African Americans. The mean cardiovascular risk scores pre-operatively versus post-operatively by ethnicity were 0.24 ± 0.20 vs 0.15 ± 0.14 (p < 0.0001) for Caucasians and 0.20 ± 0.19 vs 0.16 ± 0.17 (p = 0.23) for African Americans., Conclusions: Ethnicity does not seem to impact weight loss after BS. However, we found a significant ethnicity-elated difference in reduction of heart age and cardiovascular risk.

The single-anastomosis gastric bypass has been proposed as a simpler and efficient weight loss reducing surgery. Postoperative outcomes are comparable to those of contemporary popular procedures. There are, however, controversies regarding the efficiency and risks of one-anastomosis gastric bypass (OAGB). The purpose of this review is to define the role of OAGB in metabolic surgery via its operative outcomes. A review of English language literature was performed using the PubMed database, basing the search on the following keywords: "one-anastomosis gastric bypass" AND "outcomes". A total of 238 articles were considered for review. Following thorough screening and selection criteria, 7 articles were considered sufficient for assessment. The nature of the available evidence of this technique poses a challenge to OAGB in its establishment as a standard of care procedure. The anatomical configuration following surgery, as well as the metabolic implications of its hypo-absorptive nature, raises controversial and ongoing concerns that are yet to be addressed. Hence, prospective studies with long-term follow-up (>5 years) can bypass these concerns and allow the progression of the clinical practice of OAGB., Competing Interests: Conflicts of Interest: The focused issue “Bariatric Surgery” was commissioned by the editorial office without any funding or sponsorship.

Introduction: According to the Chronic Kidney Disease Prognosis Consortium (CKD-PC), 1 in 4 patients age ≥ 65 in North America has some form of chronic kidney disease (CKD), while 3 in 100 will progress to kidney failure. The aim of this study was to evaluate whether bariatric surgery alters the progression of CKD to kidney failure in patients who are severely obese., Methods: We conducted a retrospective review of all patients who underwent bariatric surgery at our institution over the last 16 years. Kidney function and injury were assessed using the average estimated glomerular filtration rate and urinary albumin-to-creatinine ratio (uACR) over 3 months preoperatively and postoperative at 12-month follow-up. The risk of progression from CKD to kidney failure was assessed using the Chronic Kidney Disease Prognosis Consortium (CKD-PC) equation., Results: Out of 2924 patients reviewed over this period of time, 69 (2.4%) had the recorded data necessary to assess kidney injury and the risk of disease progression to kidney failure. Patients within moderate and severe stages of CKD-related albuminuria improved the most at 12-month follow-up (by 48% and 79%; P = 0.0001 and P = 0.025, respectively). This translated to a relative risk reduction for progression to kidney failure in CKD ≥ stage 3 patients of 70% at 2 years and 60% at 5 years (both P = 0.001)., Conclusions: Bariatric surgery seems to improve kidney injury, especially among patients with the most severe stages of CKD. Marked 2- and 5-year risk reduction in the progression from CKD to kidney failure was observed.

Background: Morbid obesity is strongly associated with hypertension., Objective: The objective of this study is to compare the risk of developing hypertension before and after bariatric surgery., Setting: U.S. university hospital., Methods: We retrospectively reviewed all patients who underwent bariatric surgery from 2010 to 2015 at our institution. Nonhypertensive white individuals without diabetes at baseline were included in our study. The Framingham Hypertension Risk Score was used to predict the near-term incidence of the disease. This calculator predicts 1-, 2-, and 4-year incidence of hypertension., Results: A total of 475 patients met the criteria for the hypertension risk score calculation. Females composed 72% (n = 342) of our population with a mean age of 42.6 ± 11.6 years. Laparoscopic sleeve gastrectomy was the most prevalent procedure at 81.89% (n = 389). At 12- month follow-up, the 1-year absolute risk reduction (ARR) and the relative risk reduction (RRR) were 6.2% and 69.2% (P < .01), respectively. The 2-year ARR was 11.9%, with an RRR of 67.9% (P < .01). The 4-year risk was also calculated at 12-month follow-up, resulting in an ARR of 20.1%, and RRR of 63.7% (P < .01). Furthermore, stratifying by type of procedure, the results were comparable between sleeve gastrectomy and Roux-en-Y gastric bypass. Regarding blood pressure values at 12-month follow-up, the systolic blood pressure was reduced 11.4 mm Hg (P < .01) and the diastolic blood pressure was reduced 4.4 mm Hg (P = .07). The percentage of estimated body mass index loss at 12-month follow-up was 71.7%., Conclusions: Sleeve gastrectomy and Roux-en-Y gastric bypass significantly diminish the risk of developing hypertension in morbidly obese patients. Prospective studies are needed to better comprehend these findings., (Copyright © 2019 American Society for Bariatric Surgery. Published by Elsevier Inc. All rights reserved.)

Introduction: Atherosclerotic cardiovascular disease (ASCVD) and Framingham risk scores (FRS) are used to calculate 10-year risk of coronary death, nonfatal myocardial infarction, or fatal/nonfatal stroke. Our goal is to evaluate the association between preoperative cardiovascular risk and weight loss., Methods: We retrospectively reviewed bariatric surgeries from 2010 to 2016. Patients who met criteria for calculating 10-year ASCVD score and FRS were included. Data collected included baseline demographics, perioperative parameters, and postoperative outcomes at 12 months. Simple linear regression and multiple linear regression models were applied to test influence of individual or multiple factors of interest on 12-month weight loss outcomes., Results: Of 1330 bariatric patients studied, 360 patients met criteria for ASCVD and FRS calculation. Sleeve gastrectomy (LSG) was the most prevalent surgery 63.05%, followed by Roux-en-Y gastric bypass (LRYGB) 20.55%, revision procedures 11.9%, and adjustable gastric banding (LAGB) 4.4%. Initial BMI was 42.71 ± 7.85 kg/m 2 for females and 42.72k ± 7.42 kg/m 2 for males, with a 12-month percentage of estimated BMI loss (%EBMIL) of 66.51% in females and 60.29% in males. Preoperative 10-year ASCVD score was higher in males than females with a 34.73% relative risk reduction (RRR) in males and 35.3% RRR in females at 12-month follow-up. Regarding FRS, preoperative risk was 33.13 ± 21.1% in males and 15.71 ± 14.52% in females, with an RRR of 25.8% in males and 32.2% in females. Univariate analysis of preoperative FRS and %EBMIL showed that for every percentage unit increase in the patient's preoperative FRS, %EBMIL decreases 0.31 percentile unit (P < 0.001). Furthermore, preoperative ASCVD score is also significantly associated with %EMBIL-for every percentage unit increase in preoperative ASCVD score, %EBMIL decreases 0.42 percentile credits., Conclusion: Study results suggest ASCVD and FRS are equally reduced after bariatric surgery, especially after LSG and LRYGB. Moreover, preoperative FRS and ASCVD risk score showed an inversely proportional relationship with %EBMIL loss at 12 months.

Background: Sleeve gastrectomy (SG) is currently the most commonly performed bariatric procedure in the United States; however, it can be associated with development of de novo gastroesophageal reflux (GERD) or worsening of existing GERD. Preoperative esophagogastroduodenoscopy (EGD) and findings of esophagitis are commonly used as screening tool, but the alternative use of preoperative objective measurement of acid reflux has not been studied., Objective: The aim of this study was to evaluate if preoperative objective measurement of acid reflux by using wireless pH monitoring (WPHM) could have an impact on surgical planning and outcomes., Setting: Academic Center of Excellence., Methods: Retrospective review of a prospectively collected database of 43 adult obese patients with reflux symptoms who underwent outpatient EGD and WPHM between September 2011 and September 2017., Results: Change in planned surgical management from SG to Roux-en-Y-gastric bypass with the use of WPHM occurred in 21.0% (n = 9) of patients. Only 2.3% (n = 1) developed de novo GERD after SG. Nonerosive reflux disease was the most common esophageal condition on preoperative EGD. EGD, as a single diagnostic tool, appeared insufficient to diagnose acid reflux and help with the decision planning in this patient population., Conclusions: Based on objective data obtained by measurement of GERD, using preoperative WPHM compared with preoperative EGD alone aids in a better patient selection for either SG or Roux-en-Y-gastric bypass. Our cohort with preoperative WPHM required no surgical conversions or revisions., (Copyright © 2018 American Society for Bariatric Surgery. Published by Elsevier Inc. All rights reserved.)

Background: Obesity is a major independent risk factor for developing type 2 diabetes (T2D)., Objectives: Our goal in this study was to analyze the impact of laparoscopic sleeve gastrectomy in the risk reduction of developing T2D in middle-aged, severely obese nondiabetes patients., Setting: University Hospital, United States., Methods: We retrospectively reviewed our prospectively collected database from 2010 to 2016. All severely obese patients between 45 and 64 years of age without diabetes at baseline that underwent sleeve gastrectomy were included in our study. The T2D risk score for predicting the incidence of diabetes was measured preoperatively and at 12 months postoperatively and was based on the Framingham Offspring Study that calculates an 8-year risk of developing T2D., Results: Of the 1330 patients included in this study, 6.5% (n = 86) met the criteria for the T2D risk score calculation. The population was predominantly composed of females (68.9%; n = 59) with a mean age of 52.8 ± 5.3 years. Preoperative body mass index was 43.1 ± 6.9 kg/m 2 with a percentage of estimated body mass index loss and percentages of total weight loss were 72.2 ± 26.3% and 26.39 ± 18.15%, respectively, with fasting plasma glucose of 103.3 ± 14.9 mg/dL. The preoperative risk for T2D was 13.9 ± 11.6%, with an absolute risk reduction 12 months after surgery of 10.3%, corresponding to a 74.2% relative risk reduction. When comparing between sexes, risk reduction in females was slightly better than in males; however, this was not statistically significant. At 12-month follow-up, all measured variables were significantly improved, except for diastolic blood pressure., Conclusions: Laparoscopic sleeve gastrectomy significantly decreases the risk of developing T2D in middle-aged severely obese patients. Prospective studies are needed to further understand these findings., (Copyright © 2018 American Society for Bariatric Surgery. Published by Elsevier Inc. All rights reserved.)

Background: Bariatric surgery has proven to be the most durable treatment for obesity, and it also provides improvement of obesity's associated co-morbidities. Although several mechanisms for its metabolic effects have been studied, the implications of the surgically constructed anatomy on its functioning physiology have not been elucidated. This leaves some uncertainty regarding the recommended limb lengths in Roux-en-Y gastric bypass. The alimentary limb length and function has been studied extensively, but few have studied the influences of the biliopancreatic limb length., Objective: To present a systematic review of the literature comparing variations in length of BP limb and results in order to determine BP limb length influence., Setting: Academic Hospital, United States., Methods: We present a systematic review of all the articles comparing variations of the biliopancreatic limb length and their results., Results: Thirteen articles were identified and analyzed. Most of the articles are prospective studies. Weight loss was superior in longer limbs., Conclusion: Based on our review of the subject, we can conclude that the release of enterohormones in response to a food load in the distal small bowel seems to play an important role in the remission of co-morbidities. Hence, the length of the biliopancreatic limb might affect this process., (Copyright © 2018 American Society for Bariatric Surgery. Published by Elsevier Inc. All rights reserved.)

Background: There is a paucity of studies comparing risk reduction of the atherosclerotic cardiovascular disease (ASCVD) and Framingham-body mass index (BMI) Coronary Heart risk score after a laparoscopic Roux-en-Y gastric bypass (RYGB), and few studies have assessed the efficacy of laparoscopic sleeve gastrectomy (SG) in reducing cardiovascular risk., Objective: Our goal in this study was to compare the impact of SG and RYGB on cardiovascular risk reduction., Setting: U.S. university hospital., Methods: We retrospectively reviewed the records of all SG or RYGB cases at our institution between 2010 and 2015. Patients who met the criteria for calculating the ASCVD 10-year and Framingham-BMI score were included in the study. Propensity score matching was used to match SG and RYGB on demographic characteristics and co-morbidities., Results: Of the 1330 bariatric patients reviewed in the study period, 219 (19.3%) patients met the criteria for risk score calculation. SG was the most prevalent surgery in 72.6% (N = 159) of cases compared with RYGB in 27.4% (N = 60) of cases. At 12-month follow-up, ASCVD 10-year score had an absolute risk reduction of 3.9 ± 6.5% in SG patients and 2.9 ± 5.8% in RYGB patients (P = .3). Framingham-BMI score absolute risk reduction was 11.0 ± 12.0% in SG and 9.0 ± 11.0% in RYGB patients (P = .4), and the decrease in estimated heart age was 12.1 ± 15.6 years in SG versus 9.2 ± 9.6 years in RYGB (P = .1). The percentage of estimated BMI loss at 1 year was 68.1 ± 23.3% in SG versus 74.2 ± 24.8% in RYGB (P = .1)., Conclusion: Our results suggest that SG and RYGB are equally effective in improving cardiovascular risk and decreasing the estimated vascular/heart age at 12-month follow-up., (Copyright © 2018 American Society for Bariatric Surgery.

Background: Bariatric surgery has been shown to be safe and effective in patients aged 60-75 years; however, outcomes in patients aged 75 or older are undocumented., Methods: Patients aged 75 years and older who underwent bariatric procedures in two academic centers between 2006 and 2015 were studied., Results: A total of 19 patients aged 75 years and above were identified. Eleven (58%) were male, the median age was 76 years old (range 75-81), and the median preoperative body mass index (BMI) was 41.4 kg/m 2 (range 35.8-57.5). All of the bariatric procedures were primary procedures and performed laparoscopically: sleeve gastrectomy (SG) (n = 11, 58%), adjustable gastric band (AGB) (n = 4, 21%), Roux-en-Y gastric bypass (RYGB) (n = 2, 11%), banded gastric plication (n = 1, 5%), and gastric plication (n = 1, 5%). The median operative time was 120 min (range 75-240), and the median length of stay was 2 days (range 1-7). Three patients (16%) developed postoperative atrial fibrillation which completely resolved at discharge. At 1 year, the median percentage of total weight loss (%TWL) was 18.4% (range 7.4-22.0). The 1-year %TWL varied among the bariatric procedures performed: SG (21%), RYGB (22%), AGB (7%), and gastric plication (8%). There were no 30-day readmissions, reoperations, or mortalities., Conclusion: Our experience suggests that bariatric surgery in selected patients aged 75 years and older would be safe and effective despite being higher risk. Age alone should not be the limiting factor for selecting patients for bariatric surgery.

Background: Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal tumors of the gastrointestinal tract. Complete surgical resection of localized GISTs is the only chance of cure for patients. Laparoscopic resections (LAP) have been widely accepted as a reasonable approach to treat gastric GISTs. The current study compares operative outcomes of laparoscopic and open resection of gastric GISTs., Materials and Methods: We retrospectively reviewed patients with primary gastric GISTs who underwent surgical resection between 2003 and 2015., Results: Of a total of 89 patients, 24 (27%) patients underwent open resection (OPEN), and 65 (73%) underwent LAP. LAP or OPEN did not differ with respect to gender, body mass index, and age. Median blood loss was significantly lower in LAP than in OPEN resection (32.5 mL versus 100 mL, P < .01). Both tumor location and median operative time were comparable between LAP and OPEN (108 versus 108 min, P = .93). Median tumor size in OPEN was significantly larger than LAP tumors (6.5 versus 3.8 cm, P < .01). LAP resection yielded a shorter hospital stay (3.0 versus 6.0 days P < .01) and lower 30-day readmission rate (17% versus 0%; P < .01). Complication rates were 9% after LAP and 12% after OPEN (P = .652). Two patients in each group died during the study period. Kaplan-Meier analysis for overall survival showed no significant difference between LAP and OPEN (P = .23)., Conclusions: LAP of gastric GISTs resulted in similar operative time and survival rate, but shorter hospital stay compared with open resection. Consequently, whenever possible, the laparoscopic approach should be preferably used for treatment of gastric GISTs. However, advanced tumor stage might dictate the need for open procedure with expected worse results.

Background: Paradoxically, advances in anti-retroviral therapy that has increased survival for patients with human immunodeficiency virus (HIV) have resulted in greater numbers of HIV+ patients developing other chronic diseases, including obesity. Little comparative literature exists detailing perioperative or metabolic outcomes of bariatric surgery in the HIV+ population compared to HIV negative (HIV-) controls., Methods: This is a retrospective case-control study with both HIV+ (case) and HIV- control patients. Individuals undergoing sleeve gastrectomy (SG) or Roux-en-Y gastric bypass (RYGB) between January 1, 2006 and December 31, 2015 were included. HIV+ status was defined as any individual with documented history of HIV., Results: Eleven HIV+ patients underwent RYGB or SG during the study period. After matching (1:5 HIV+: HIV-) both cohorts had similar mean age (42 years), gender distribution (63% female), and preoperative BMI (48 kg/m2), as well as comorbidities. There were no differences in postoperative length of stay, or all cause 30-day morbidity. There were 63.7% HIV+ and 76.4% with 1-year follow-up available. Both percent excess weight loss (56% HIV+ vs. 60% HIV-) and BMI (32 HIV+ vs. 34 kg/m2 HIV-) were similar in both groups. There were minimal changes to CD4 count or HIV viral load in the patients during the follow-up period., Conclusion: Bariatric surgery is safe and feasible in HIV-infected population well controlled on anti-retroviral medication. The short-term surgical and metabolic outcomes are similar to HIV- controls with minimal effect on the CD4 count and viral load in HIV+ cohort for long-term follow-up.

Background: There is vast evidence that supports the importance of obesity in the pathogenesis and progression of cardiovascular disease. Rapid weight loss induced by laparoscopic Roux-en-Y gastric bypass (RYGB) and adjustable gastric banding (LAGB) has proven beneficial. The aim of this study is to evaluate laparoscopic sleeve gastrectomy (LSG) as an alternative treatment modality and its impact on the Framingham-BMI 10-year risk score., Methods: We retrospectively reviewed all patients that underwent bariatric surgery at our institution between 2010 and 2014. Patients who met the criteria for calculating the Framingham BMI 10-year risk score were included. Data collected included baseline demographics, perioperative parameters such as tobacco use, diagnosis of diabetes, treatment for hypertension, BMI and postoperative outcomes at 3 and 12 months., Results: From our 1129 bariatric patients, 358 (31.7%) met criteria for the Framingham BMI 10-year risk score calculation. LSG was the most prevalent surgery 61.45% (N = 220) followed by LRYGB 22.06% (N = 79). Females composed 69% (N = 248) of our population. The average age for females was 52.3 ± 10.8 years and for males 54.07 ± 11.2 years. The initial Framingham 10-year score risk was significantly higher in males compared with females (36.16% ± 22.3 vs. 16.97% ± 15.6 (p < 0.001)). After 12-month follow-up, the absolute risk reduction in males was 11.58% (p < 0.001) and 6.17% in females (p < 0.001). The preoperative heart age was high in females and males (69.23 ± 15.72 years and 73.55 ± 13.55 years, respectively (p = 0.012)), and after 12 months it was reduced 7.19 years in females (p < 0.001) and 7.04 years in males (p < 0.001). The percentage of estimated BMI loss at 1 year was 64.43% in females and 60.69% in males., Conclusion: Sleeve gastrectomy has demonstrated to be an effective method of treatment for obesity. Our results suggest that rapid weight loss after LSG has a positive impact in the reduction of the 10-year cardiovascular disease risk. Further prospective studies may be needed to better assess these findings.

Background: Intraoperative incisionless fluorescent cholangiogram (IOIFC) has been demonstrated to be a useful tool to increase the visualization of Calot's triangle. This study evaluates the identification of extrahepatic biliary structures with IOIFC by medical students and surgery residents., Methods: Two pictures were taken, one with xenon light and one with near-infrared (NIR) light, at the same stage during dissection of Calot's triangle in ten different cases of laparoscopic cholecystectomy (LC). All twenty pictures were organized in a random fashion to remove any imagery bias. Twenty students and twenty residents were asked to identify the biliary anatomy., Results: Medical students were able to accurately identify the cystic duct on an average 33.8 % under the xenon light versus 86 % under NIR light (p = 0.0001), the common hepatic duct (CHD) on an average 19 % under the xenon light versus 88.5 % under NIR light (p = 0.0001), and the junction on an average 24 % under xenon light versus 80.5 % under NIR light (p = 0.0001). Surgery residents were able to accurately identify the cystic duct on an average 40 % under the xenon light versus 99 % under NIR light (p = 0.0001), the CHD on an average 35 % under the xenon light versus 96 % under NIR light (p = 0.0001), and the junction on an average 24 % under the xenon light versus 95.5 % under NIR light (p = 0.0001)., Conclusions: IOIFC increases the visualization of Calot's triangle structures when compared to xenon light. IOIFC may be a useful teaching tool in residency programs to teach LC.

Background: Bariatric surgery has proven to be the most effective treatment for morbid obesity in all age groups and is considered superior to medical treatment. The aim of our study was to report the outcomes of bariatric surgery in patients over 65 years of age at our institution., Methods: A retrospective review of a prospectively collected database was conducted of all patients > 65 years who underwent a bariatric procedure between 2005 and 2015 at our institution. We compared this group to a control group of patients < 65 years of age who were operated on during the last 5 years, from 2011 to 2015. Data analyzed included age, preoperative BMI, postoperative complications, and comorbidities., Results: Of 1613 patients studied, 1220 patients were under 65 years of age, and in Group B, 393 were >65 years of age at time of surgery. There was a significant difference in proportion of male patients among groups; 42 % in Group B were male compared to 30 % in Group A (p < 0.001). Caucasians represented the majority in both groups. Both groups had comparable preoperative BMI 42.27 kg/m 2 for the younger Group A population versus 41.64 kg/m 2 for Group B (p = 0.074). Group B had more comorbidities than Group A: hypertension (p < 0.001), sleep apnea (p < 0.001), and hypercholesterolemia (p < 0.001). No difference was found between groups in history of depression (p = 0.409) or type II diabetes (p = 0.961). Distribution of procedures was significantly different between groups, with more LSG in Group A (p < 0.001). Elderly patients had longer length of stay (LOS) by one day on average (LOS = 3 days, p < 0.001), but a lower readmission rate (10 % vs. 7 %) (p = 0.023). Complication rates were comparable in both groups, except for incidence of de novo GERD, which was higher in Group B (5 % vs. 8 %) (p = 0.005)., Conclusions: Elderly patients are usually sicker in terms of comorbidities than the younger population. However, age does not seem to represent a risk of surgical complications after bariatric surgery.

A wandering liver is a rare development in both the adult and pediatric population where the liver is freely displaced along a transverse axis. We describe the first known occurrence in published literature of a wandering liver in an adult individual who also had an intestinal malrotation complicated by a midgut volvulus. The abnormal ability for a liver to wander presents a highly unusual anatomy that can be disorienting. Laparoscopic surgery is a viable option in reducing a midgut volvulus and addressing an intestinal malrotation in the presence of a wandering liver. This unusual presentation educates clinicians to avoid potential misdiagnosis given the abnormal location of the duodenum, appendix, liver, and gallbladder.

Laparoscopic adjustable gastric banding (LAGB) is considered the simplest of the bariatric operations. Although studies have confirmed the effectiveness of the LAGB in terms of weight loss and resolution of comorbidities, concerns have developed over its long-term efficacy and safety. Reports have described a high incidence of complications and need for reintervention. These reports and the availability of other effective and well-tolerated procedures have determined a significant decrease in the number of LAGBs performed. This article reviews key historic milestones, fundamental changes in the design and technique, and potential reasons that determined a quick rise and a progressive fall of LAGB's popularity., (Copyright © 2016 Elsevier Inc.

Background: LSG is widely accepted as a definitive treatment for obesity. Due to lack of large series with long-term follow-up, disagreement remains regarding its safety and efficacy. We present a series of 1020 consecutive LSGs performed with long-term follow-up., Methods: A retrospective review of a prospectively collected database was conducted on patients who underwent LSG from January 2005 to February 2014. Data included weight, height, BMI, ideal body weight, comorbid conditions, intraoperative complications, mean length of hospital stay (LOS), early (<30 days) readmission, early and late (>30 days) postoperative complications, and percentage of excess weight loss (%EWL)., Results: Of the 1020 patients, 66.6 % (n = 679) were female, with a mean age of 38.4 ± 16.5 years. Mean BMI at the time of first visit was 43.4 ± 5.8 kg/m(2). The most common comorbid conditions identified were diabetes mellitus (89.4 %), sleep apnea (86.4 %), hypertension (80.3 %), and hyperlipidemia (70 %). Over the entire follow-up period, 57 % of diabetic patients experienced significant improvement or remission. There was no mortality in this series. Early postoperative complications within 30 days of surgery included leak in 0.1 % (n = 1), stricture in 0.1 % (n = 1), emesis in 23 % (n = 234), dehydration in 19 % (n = 194), prolonged ileus in 18 % (183), and self-limited bleeding in 3 % (n = 30). Mean LOS was of 3.4 ± 2.1 days, with a 3.8 % overall rate of early readmissions. Long-term morbidity was found in 3.9 % of patients (n = 40) and included stricture in 0.49 % (n = 5) and GERD in 6 % (n = 61). The overall 30-day mortality rate was 0 %. Mean %EWL at 3 months to 1, 3, 5, and 8 years was 72 ± 16.8, 86 ± 22.3, 63 ± 19, 61 ± 11, and 52 ± 9.2, respectively., Conclusions: This study confirms that LSG is safe and has very low rates of early and long-term complications when compared to other well-established procedures. Additionally, LSG that appears results in significant improvement of obesity-related comorbid conditions.

Background: Laparoscopic sleeve gastrectomy (LSG) has become the most common weight loss surgery procedure. The procedure's most dreaded surgical complication is staple-line disruption (SLD). So far, no definitive treatment modality has been established for this complication., Objectives: The aim of this study is to review the treatment options used at our institution for patients with SLD after LSG and to evaluate the outcome of different interventions., Methods: A retrospective review of a prospectively collected database of all patients who underwent SLD between January 2005 and April 2014 was performed. SLD was defined as a leak identified on computed tomography or upper gastrointestinal series. We compared the cure rate between a major surgical procedure and patients treated with a variety of other minor treatment modalities. Special focus is given to the technique of proximal gastrectomy with Roux-en-Y esophagojejunostomy (PGEJ). The procedure consists of the en bloc resection of the proximal stomach immediately proximal to the gastroesophageal junction and including the fistulous tract. The jejunum is transected 50 cm distal to the ligament of Treitz and reconstruction of the gastrointestinal tract is performed with a Roux-en-Y esophagojejunostomy., Results: Thirty-one patients had SLD after their LSG. Patients were divided into 2 groups based on the treatment modality: Group A (PGEJ) and Group B (minor surgical procedure). Group A (n = 19) had 1 releak. Group B (n = 11) had 5 releaks. The cure rate for patients who underwent PGEJ was 94.7%. The cure rate for patients who were treated with a different approach was 54.5% (P = .01)., Conclusion: Our experience demonstrates that the cure rate of PGEJ is high. Minor surgical procedures are effective in approximately half of the patients, so when the leak becomes chronic, PGEJ can provide a long-term solution., (Copyright © 2016 American Society for Bariatric Surgery.
