Background: Our aim was to evaluate the influence of staged goal directed therapy (GDT) on postoperative pulmonary complications (PPCs), intraoperative hemodynamics and oxygenation in patients undergoing Mckeown esophagectomy. Methods: Patients were randomly divided into three groups, staged GDT group (group A, n = 56): stroke volume variation (SVV) was set at 8–10% during the one lung ventilation (OLV) stage and 8–12% during the two lung ventilation (TLV) stage, GDT group (group B, n = 56): received GDT with a target SVV of 8–12% During the entire surgical procedure, and control group (group C, n = 56): conventional fluid therapy was administered by mean arterial pressure (MAP), central venous pressure (CVP), and urine volume. The primary outcome was the incidence of postoperative pulmonary complications within Postoperative days (POD) 7. The secondary outcomes were postoperative lung ultrasound (LUS) B-lines artefacts (BLA) scoring, incidence of other complications, the length of hospital stay, intraoperative hemodynamic and oxygenation indicators included mean arterial pressure (MAP), heart rate (HR), cardiac index (CI), cardiac output (CO), oxygenation index (OI), respiratory indices (RI), alveolar-arterial oxygen difference (Aa-DO2). Results: Patients in group A and group B had a lower incidence of PPCs (7/56 vs. 17/56 and 9/56 vs. 17/56, p < 0.05), and a fewer B-lines score on postoperative ultrasound (4.61 ± 0.51 vs. 6.15 ± 0.74 and 4.75 ± 0.62 vs. 6.15 ± 0.74, p < 0.05) compared to group C. The CI, CO, MAP, and OI were higher in group A compared to group B and group C in the stage of thoracic operation. During the abdominal operation stage, patients in group A and group B had a better hemodynamic and oxygenation indicators than group C. Conclusions: In comparison to conventional fluid therapy, intraoperative staged GDT can significantly reduce the incidence of postoperative pulmonary complications in patients undergoing McKeown esophagectomy, facilitating patient recovery. Compared to GDT, it can improve intraoperative oxygenation and stabilize intraoperative hemodynamics in patients. Trial registration: This study was registered in the Chinese Clinical Trial Registry on 24/11/2021 (ChiCTR2100053598). [ABSTRACT FROM AUTHOR]

Introduction: Studying surgical services and the workforce in sub-Saharan Africa is crucial for enhancing access to quality surgical care in the region. Despite many recommendations to produce evidence based on reliable data on this subject to guide policymakers, there is still a knowledge gap on this topic. The aim of this nationwide survey was to describe the organization of abdominal emergency surgical care across healthcare services in Senegal. Methodology: This was a cross-sectional nationwide survey. The study period was between October 1st, 2023, and January 20th, 2024. The target population included all registered healthcare facilities in Senegal offering emergency surgical services. A structured questionnaire was designed to gather infrastructure-related data, surgical activities, and human resources. Results: All 33 identified healthcare facilities responded to the survey (100%). Emergency abdominal surgery services were available for 96.7% of the surveyed structures. The teams were mainly composed of surgeons and residents (45.2%) or surgeons and medical trainees (48.8%). The average bed capacity of the services was 21.9, with a standard deviation of 13.9. The absence of a dedicated hospitalization section for patients requiring special monitoring was found in 69.6% of the facilities. Operating rooms dedicated to emergency abdominal digestive surgery were present in 54.6% of the services. On average, the services performed 17.6 scheduled surgical interventions with a standard deviation of 11.5 and 29.7 emergency surgical interventions with a standard deviation of 16.8 per month. Morbidity and mortality conferences were not routinely held in the majority of departments (only 27.3%). Professional development programmes were present only in 24.2% of departments. Most of the departments did not have adequate human resources (69.6%). A total of 70 surgeons were identified, resulting in a national ratio of 0.39 general surgeons per 100,000 inhabitants. The strategies employed to address staff shortages included additional working hour by staff (54.5%), temporary workers (30.3%) or the use of trainee doctors or nurses (12.1%). Conclusion: This research shows that significant deficiencies are present in the essential physical and human resources needed to conduct fundamental life-saving surgical procedures. These findings suggest potential areas for improvement in the delivery of emergency surgical care in the region. [ABSTRACT FROM AUTHOR]

Background: The perioperative management of patients with chronic cough or cough hypersensitivity syndrome and its sometimes severe effects is currently under-researched and under-reported. Case presentation: A 46-year-old female patient with a history of chronic cough and Cough Hypersensitivity Syndrome. After laparoscopic hiatoplasty and anterior fundoplication under general anesthesia, experienced a pronounced exacerbation of coughing symptoms. Despite prompt and extensive treatment involving antitussives, inhalants, anxiolytics, and sedatives, the symptoms remained uncontrollable. Within a few hours, the patient developed a respiratory alkalosis with severe and life-threatening electrolyte shift (pH 7.705, pCO2 1.72 kPa, K+ 2.1 mmol/l). Lactatemia lasted for more than 12 hours with values up to 6.6 mmol/l. Acute bleeding, pneumothorax, and an acute cardiac event were ruled out. Deep analgosedation and inhalation of high-percentage local anesthetics were necessary to manage the clinical symptoms. Conclusions: This case highlights the challenging nature of chronic cough and hypersensitivity syndrome perioperatively. A tailored anesthesiologic approach, exclusion of other provoking medical problems, and knowledge of possible management and treatment options are key. [ABSTRACT FROM AUTHOR]

Simple Summary: Preoperative risk prediction prior to oncologic esophagectomy is crucial for assisting surgeons in accurate patient selection and patients in their informed decision making. A new risk stratification tool, the IESG prediction model, was recently introduced, categorizing patients into different risk levelsMachine learning is a subfield of artificial intelligence and may allow for a more accurate identification of patients at risk. Therefore, we evaluated the IESG risk model and compared its performance with ML models. We found that the IESG risk model provided an overall adequate risk estimation. However, ML showed better results in the accurate risk stratification of patients, demonstrating its potential as a novel and powerful approach for future patient assessment. Risk prediction prior to oncologic esophagectomy is crucial for assisting surgeons and patients in their joint informed decision making. Recently, a new risk prediction model for 90-day mortality after esophagectomy using the International Esodata Study Group (IESG) database was proposed, allowing for the preoperative assignment of patients into different risk categories. However, given the non-linear dependencies between patient- and tumor-related risk factors contributing to cumulative surgical risk, machine learning (ML) may evolve as a novel and more integrated approach for mortality prediction. We evaluated the IESG risk model and compared its performance to ML models. Multiple classifiers were trained and validated on 552 patients from two independent centers undergoing oncologic esophagectomies. The discrimination performance of each model was assessed utilizing the area under the receiver operating characteristics curve (AUROC), the area under the precision–recall curve (AUPRC), and the Matthews correlation coefficient (MCC). The 90-day mortality rate was 5.8%. We found that IESG categorization allowed for adequate group-based risk prediction. However, ML models provided better discrimination performance, reaching superior AUROCs (0.64 [0.63–0.65] vs. 0.44 [0.32–0.56]), AUPRCs (0.25 [0.24–0.27] vs. 0.11 [0.05–0.21]), and MCCs (0.27 ([0.25–0.28] vs. 0.15 [0.03–0.27]). Conclusively, ML shows promising potential to identify patients at risk prior to surgery, surpassing conventional statistics. Still, larger datasets are needed to achieve higher discrimination performances for large-scale clinical implementation in the future. [ABSTRACT FROM AUTHOR]

Background: Artificial intelligence (AI) models have been applied in various medical imaging modalities and surgical disciplines, however the current status and progress of ultrasound-based AI models within hepatopancreatobiliary surgery have not been evaluated in literature. Therefore, this review aimed to provide an overview of ultrasound-based AI models used for hepatopancreatobiliary surgery, evaluating current advancements, validation, and predictive accuracies. Method: Databases PubMed, EMBASE, Cochrane, and Web of Science were searched for studies using AI models on ultrasound for patients undergoing hepatopancreatobiliary surgery. To be eligible for inclusion, studies needed to apply AI methods on ultrasound imaging for patients undergoing hepatopancreatobiliary surgery. The Probast risk of bias tool was used to evaluate the methodological quality of AI methods. Results: AI models have been primarily used within hepatopancreatobiliary surgery, to predict tumor recurrence, differentiate between tumoral tissues, and identify lesions during ultrasound imaging. Most studies have combined radiomics with convolutional neural networks, with AUCs up to 0.98. Conclusion: Ultrasound-based AI models have demonstrated promising accuracies in predicting early tumoral recurrence and even differentiating between tumoral tissue types during and after hepatopancreatobiliary surgery. However, prospective studies are required to evaluate if these results will remain consistent and externally valid. [ABSTRACT FROM AUTHOR]

Introduction: Peroral endoscopic myotomy (POEM) is the standard treatment for achalasia. Functional luminal imaging probe (FLIP) technology enables objective measurement of lower esophageal sphincter (LES) geometry, with literature linking specific values to improved post-POEM outcomes. Our study assesses FLIP's intraoperative use in evaluating myotomy extent in real-time. Methods: Retrospective data from all patients undergoing POEM with intraoperative FLIP measurements were extracted from June 2020 to January 2023. The primary endpoint was intraoperative FLIP measurements, management changes, and symptom improvement (Eckardt score). Results: Fourteen patients (age 56 ± 14 years, BMI 28 ± 7 kg/m2) were identified. Most patients were female (64%). Predominantly, patients presented with type II achalasia (50%). FLIP measurements were taken before and after myotomy, demonstrating increases in mean distensibility index (DI) 1.6 ± 1. 4 to 5.4 ± 2.1 mm2/mmHg (p < 0.05) and mean diameter (Dmin) 6 ± 1.8 to 10.9 ± 2.3 mm (p < 0.05) at 50 ml balloon fill. Additional myotomy was performed in one patient when an inadequate increase in FLIP values were noted. Mean operative time was 98 ± 28 min, and there were no intraoperative complications. At the 30-day follow-up, median Eckardt score decreased from mean a preoperative score of 7 ± 2 to a post-operative mean of 2 ± 3, with 10 patients (78%) having a score ≤ 2. In total, four patients experienced symptom recurrence, with repeat FLIP values revealing a significant decrease in DI from 7 ± 2.2 post-POEM to 2.5 ± 1.5 at recurrence. FLIP technology identified LES pathology in 3 out of 4 (75%) patients, facilitating referral to LES-directed therapy. Conclusion: Our study adds to the literature supporting the use of FLIP technology during the POEM procedure, with most patients achieving ideal values after a standard-length myotomy. This suggests the potential benefits of shorter myotomies guided by FLIP to achieve comparable outcomes and reduce postoperative GERD risk. Collaborative standardization of study designs and outcome measures is crucial for facilitating prospective trials and cross-setting outcome comparisons. [ABSTRACT FROM AUTHOR]

Introduction: Health literacy is the ability of individuals to use basic health information and services to make well-informed decisions. Low health literacy among surgical patients has been associated with nonadherence to preoperative and/or discharge instructions as well as poor comprehension of surgery. It likely poses as a barrier to patients considering foregut surgery which requires an understanding of different treatment options and specific diet instructions. The objective of this study was to assess and compare the readability of online patient education materials (PEM) for foregut surgery. Methods: Using Google, the terms "anti-reflux surgery, "GERD surgery," and "foregut surgery" were searched and a total of 30 webpages from universities and national organizations were selected. The readability of the text was assessed with seven instruments: Flesch Reading Ease formula (FRE), Gunning Fog (GF), Flesch-Kincaid Grade Level (FKGL), Coleman Liau Index (CL), Simple Measure of Gobbledygook (SMOG), Automated Readability Index (ARI), and Linsear Write Formula (LWF). Mean readability scores were calculated with standard deviations. We performed a qualitative analysis gathering characteristics such as, type of information (preoperative or postoperative), organization, use of multimedia, inclusion of a version in another language. Results: The overall average readability of the top PEM for foregut surgery was 12th grade. There was only one resource at the recommended sixth grade reading level. Nearly half of PEM included some form of multimedia. Conclusions: The American Medical Association and National Institute of Health have recommended that PEMs to be written at the 5th–6th grade level. The majority of online PEM for foregut surgery is above the recommended reading level. This may be a barrier for patients seeking foregut surgery. Surgeons should be aware of the potential gaps in understanding of their patients to help them make informed decisions and improve overall health outcomes. [ABSTRACT FROM AUTHOR]

Background: An increasing number of reflux patients opt for magnetic sphincter augmentation (MSA) instead of fundoplication. However, few studies compare the medium-term efficacy and safety of the procedures. Methods: We conducted a retrospective single-center analysis of consecutive MSA and Nissen fundoplication cases between 01/2015 and 06/2020. Patients underwent surgery, including hiatoplasty, for medical treatment-resistant reflux due to hiatal hernia. Surgical revision and proton pump inhibitor (PPI) reuptake rates were the primary outcomes. We also compared adverse event rates. Patients with severe preoperative dysphagia/motility disorders were assigned different treatment pathways and excluded from the analysis. We used propensity-score matching to reduce confounding between treatments. Results: Out of 411 eligible patients, 141 patients who underwent MSA and 141 with fundoplication had similar propensity scores and were analyzed. On average, patients were 55 ± 12 years old and overweight (BMI: 28 ± 5). At 3.9 years of mean follow-up, MSA was associated with lower surgical revision risk as compared to fundoplication (1.2% vs 3.0% per year, respectively; HR: 0.38; 95% CI 0.15–0.96; p = 0.04), and similar PPI-reuptake risk (2.6% vs 4.2% per year; HR: 0.59; 95% CI 0.30–1.16; p = 0.12). Adverse event rates during primary stay were similar (MSA vs. fundoplication: 1% vs. 3%, p = 0.68). Fewer patients experienced adverse events in the MSA group after discharge (24% vs. 33%, p = 0.11), driven by higher rates of self-limiting dysphagia (1% vs. 9%, p < 0.01) and gas/bloating (10% vs. 18%, p = 0.06) after fundoplication. Differences between MSA and fundoplication in dysphagia requiring diagnostic endoscopy (11% vs. 8%, p = 0.54) or surgical revision (2% vs. 1%, p = 1.0) were non-significant. The device explantation rate was 4% (5/141). Conclusion: MSA reduces the re-operation risk compared to fundoplication and may decrease adverse event rates after discharge. Randomized head-to-head studies between available surgical options are needed. [ABSTRACT FROM AUTHOR]

Background: Thoracic esophageal cancer surgery using robotic approaches for the thoracic and abdominal parts has recently been reported as total robot-assisted minimally invasive esophagectomy (RAMIE). We herein present the first report of a new technique for esophageal cancer: total RAMIE with three-field lymph node dissection (3FLND) by a simultaneous two-team approach using a new docking method. Methods: We reviewed 20 patients who underwent total RAMIE with 3FLND by a simultaneous two-team approach at the National Cancer Center East Hospital from March 2023 to September 2023. Short-term surgical outcomes and the safety and efficacy of this technique were analyzed. Results: The mean operative time for abdominal surgery with this new docking technique was 135 ± 19.6 min. The total operative time was 488 ± 42.9 min, and the time from the end of abdominal manipulation to the end of surgery was 80.1 ± 15.6 min. The intraoperative blood loss was 116.7 ± 64.4 mL. The incidence of anastomotic leakage, postoperative vocal cord paralysis, and postoperative pneumonia was 10%, 5%, and 10%, respectively. The median postoperative hospital stay was 14 days (range 11–63 days). No in-hospital deaths occurred, and R0 resection was possible in all cases. The average number of lymph nodes dissected was 87.7. Conclusion: These results demonstrate that total RAMIE with a simultaneous two-team approach using the new docking method can be safely introduced. The simultaneous cervical and abdominal manipulation with the new docking method allowed total RAMIE without prolonging the operating time, suggesting that it may be a valuable approach for esophageal cancer surgery.

Hydatid disease, caused primarily by Echinococcus granulosus, is prevalent in regions where livestock farming is common. Although typically considered benign, ruptured hydatid cysts into the abdominal cavity present a rare but severe complication requiring urgent surgical intervention. We hydatid liver cyst, emphasizing the unprecedented nature of this occurrence, as it has never been reported in the literature before. The case underscores the role of computed tomography (CT) imaging in diagnosis and multidisciplinary management involving emergency physicians, radiologists, anesthetists, and surgeons. Key points highlighted include the rarity of postpartum hydatid cyst rupture, the diagnostic utility of CT scans, and the necessity of immediate surgical intervention. Surgical strategies include conservative techniques and intraoperative lavage with hypertonic saline solution to prevent recurrence. Postoperative albendazole therapy and regular follow-up aid in preventing recurrence and early detection of complications. This case underscores the importance of suspecting ruptured hydatid cysts in postpartum women with underlying hepatic hydatid cyst and features of peritonitis, necessitating prompt recognition and management of complications in hydatid disease [ABSTRACT FROM AUTHOR]

Introduction: Informed consent is essential in ensuring patients' understanding of their medical condition, treatment, and potential risks. The objective of this study was to investigate the impact of utilizing a video consent compared to standard consent for patient knowledge and satisfaction in selected general surgical procedures. Methods and procedures: We included 118 patients undergoing appendectomy, cholecystectomy, inguinal hernia repair, and fundoplication at two hospitals in Omaha, NE. Patients were randomized to either a standard consent or a video consent. Outcomes included a pretest and posttest objective knowledge assessment of their procedure, as well as a satisfaction survey which was completed immediately after consent and following discharge. Given the pre-post design, a linear mixed-effect model was estimated for both outcomes. A two-way interaction effect was of primary interest to assess whether pre-to-post change in the outcome differed between patients randomized to standard or video consent. Results: Baseline characteristics were mostly similar between groups except for patient sex, p = 0.041. Both groups showed a statistically significant increase in knowledge from pretest to posttest (standard group: 0.25, 95% CI 0.01 to 0.51, p = 0.048; video group: 0.68, 95% CI 0.36 to 1.00, p < 0.001), with the video group showing significantly greater change (interaction p = 0.043) indicating that incorporating a video into the consent process resulted in a better improvement in patient's knowledge of the proposed procedure. Further, both groups showed a decrease in satisfaction post-discharge, but no statistically significant difference in the magnitude of decrease between the groups (interaction p = 0.309). Conclusion: Video consent lead to a significant improvement in a patient's knowledge of the proposed treatment. Although the patient satisfaction survey didn't show a significant difference, it did show a trend. We propose incorporating videos into the consent process for routine general surgical procedures.

Background: Anastomotic leak after esophagectomy is a major contributor to surgery-related morbidity and mortality. The purpose of this systematic review was to evaluate if positive-smoking status is associated with the incidence of this complication. Methods: A systematic search of MEDLINE, EMBASE, Scopus, Web of Science and Cochrane Library was performed on April 4th, 2023. Inclusion criteria comprised human participants undergoing esophagectomy, age ≥ 18, n ≥ 5, and identification of smoking status. The primary outcome was incidence of anastomotic leak. Sub-group analysis by ex- or current smoking status was performed. Meta-analysis was performed with RevMan 5.4.1 using a Mantel–Haenszel random-effects model. Publication bias was evaluated visually with funnel plots and through the Egger test. Results: A total of 220 abstracts were screened, of which 69 full-text studies were assessed for eligibility, with 13 studies selected for final inclusion. This included 16,103 patients, of which 4433 were ex- or current smokers, and 9141 were never smokers. Meta-analysis revealed an increased odds of anastomotic leak in patients with a positive-smoking status (current or ex-smokers) compared to never smokers (OR 1.44, 95% CI 1.18–1.76, I2 = 44%, p < 0.001. Meta-analysis of six studies comparing active smokers alone to never smokers identified a significant increased odds of anastomotic leak (OR 1.80, 95% CI 1.25–2.59, p = 0.002, I2 = 0%). Meta-analysis of five studies comparing ex-smokers to never smokers identified a significant increased odds of anastomotic leak (OR 1.36, 95% CI 1.02–1.82, p = 0.04, I2 = 0%). The odds of anastomotic leak decreased among ex-smokers compared to active smokers. Conclusion: The findings of this systematic review and meta-analysis support the association between positive-smoking status and the risk of anastomotic leak after esophagectomy. Results further emphasize the importance of preoperative smoking cessation to reduce post-operative morbidity. [ABSTRACT FROM AUTHOR]

Background: Although myotomy is crucial in peroral endoscopic myotomy (POEM) surgeries, its optimum length remains controversial. Herein, we propose a modified POEM with new method of tailoring myotomy length aim to evaluate the safety, efficacy, and clinical outcomes of this modified POEM compared with standard POEM in type I or II achalasia. Methods: Seventy-five patients with type I or II achalasia who underwent POEM at the First Hospital of Jilin University between January 2018 and December 2022 were retrospectively analyzed. According to the myotomy approach, these patients were divided into the retrograde on-demand myotomy (RDM, n = 34), with myotomy beginning on gastric side and length tailored by determining the degree of lower esophageal sphincter (LES) distention, and standard myotomy (SM, n = 41) groups. The baseline data, myotomy length, operation time, clinical success rate, adverse event rate, and reflux-related adverse events were compared and analyzed. Results: The median myotomy length in the RDM group was significantly shorter than that in the SM group (6 vs. 8 cm, respectively; p < 0.001). Moreover, the median myotomy time in the RDM group was significantly shorter than that in the SM group (10 vs. 16 min, respectively; p < 0.001). POEM was successfully performed in all the patients. At the 2-year follow-up, high clinical success rates were observed in both the RDM and SM groups (92.0% vs. 93.3%, respectively; p = 1.000). The incidence of intraoperative adverse events and postoperative reflux-related adverse events was low and comparable in both groups. Conclusions: RDM POEM is a safe and effective method for patients with type I or II achalasia. Furthermore, it has a shorter myotomy length and operation time than standard POEM technique.

Background: Although minimally invasive hepato-pancreato-biliary (MIS HPB) surgery can be performed with good outcomes, there are currently no standardized requirements for centers or surgeons who wish to implement MIS HPB surgery. The aim of this study was to create a consensus statement regarding safe dissemination and implementation of MIS HPB surgical programs. Methods: Sixteen key questions regarding safety in MIS HPB surgery were generated after a focused literature search and iterative review by three field experts. Participants for the working group were then selected using sequential purposive sampling and snowball techniques. Review of the 16 questions took place over a single 2-h meeting. The senior author facilitated the session, and a modified nominal group technique was used. Results: Twenty three surgeons were in attendance. All participants agreed or strongly agreed that formal guidelines should exist for both institutions and individual surgeons interested in implementing MIS HPB surgery and that routine monitoring and reporting of institutional and surgeon technical outcomes should be performed. Regarding volume cutoffs, most participants (91%) agreed or strongly agreed that a minimum annual institutional volume cutoff for complex MIS HPB surgery, such as major hepatectomy or pancreaticoduodenectomy, should exist. A smaller proportion (74%) agreed or strongly agreed that a minimum annual surgeon volume requirement should exist. The majority of participants agreed or strongly agreed that surgeons were responsible for defining (100%) and enforcing (78%) guidelines to ensure the overall safety of MIS HPB programs. Finally, formal MIS HPB training, minimum case volume requirements, institutional support and infrastructure, and mandatory collection of outcomes data were all recognized as important aspects of safe implementation of MIS HPB surgery. Conclusions: Safe implementation of MIS HPB surgery requires a thoughtful process that incorporates structured training, sufficient volume and expertise, a proper institutional ecosystem, and monitoring of outcomes.

BACKGROUND: Laparoscopic surgery remains the mainstay of treating foregut pathologies. Several studies have shown improved outcomes with the robotic approach. A systematic review and meta-analysis comparing outcomes of robotic and laparoscopic hiatal hernia repairs (HHR) and Heller myotomy (HM) repairs is needed. STUDY DESIGN: PubMed, EMBASE, and SCOPUS databases were searched for studies published between January 2010 and November 2022. The risk of bias was assessed using the Cochrane Risk of Bias in Non-Randomized Studies of Interventions tool. Assessed outcomes included intraand postoperative outcomes. We pooled the dichotomous data using the Mantel-Haenszel random-effects model to report odds ratio (OR) and 95% CIs and continuous data to report mean difference and 95% CIs. RESULTS: Twenty-two comparative studies enrolling 196,339 patients were included. Thirteen (13,426 robotic and 168,335 laparoscopic patients) studies assessed HHR outcomes, whereas 9 (2,384 robotic and 12,225 laparoscopic patients) assessed HM outcomes. Robotic HHR had a nonsignificantly shorter length of hospital stay (LOS) (mean difference -0.41, 95% CI -0.87 to -0.05), fewer conversions to open (OR 0.22, 95% CI 0.03 to 1.49), and lower morbidity rates (OR 0.76, 95% CI 0.47 to 1.23). Robotic HM led to significantly fewer esophageal perforations (OR 0.36, 95% CI 0.15 to 0.83), reinterventions (OR 0.18, 95% CI 0.07 to 0.47) a nonsignificantly shorter LOS (mean difference -0.31, 95% CI -0.62 to 0.00). Both robotic HM and HHR had significantly longer operative times. CONCLUSIONS: Laparoscopic and robotic HHR and HM repairs have similar safety profiles and perioperative outcomes. Randomized controlled trials are warranted to compare the 2 methods, given the low-to-moderate quality of included studies. [ABSTRACT FROM AUTHOR]

The introduction of new technologies in current digestive surgical practice is progressively reshaping the operating room, defining the fourth surgical revolution. The implementation of black boxes and control towers aims at streamlining workflow and reducing surgical error by early identification and analysis, while augmented reality and artificial intelligence augment surgeons' perceptual and technical skills by superimposing three-dimensional models to real-time surgical images. Moreover, the operating room architecture is transitioning toward an integrated digital environment to improve efficiency and, ultimately, patients' outcomes. This narrative review describes the most recent evidence regarding the role of these technologies in transforming the current digestive surgical practice, underlining their potential benefits and drawbacks in terms of efficiency and patients' outcomes, as an attempt to foresee the digestive surgical practice of tomorrow.

Background: The gold standard for resectable, locally advanced esophageal squamous cell carcinoma (ESCC) is surgery‐based treatment; however, it is unclear whether esophagectomy or chemoradiotherapy is suitable for older patients. This retrospective study aimed to identify the treatment outcomes of surgery‐based therapy versus definitive chemoradiotherapy (dCRT) as an initial treatment for older patients with resectable, locally advanced ESCC. Methods: Data from 434 patients who received radical treatment for resectable, locally advanced ESCC were collected from January 2011 to December 2020. Of the patients >75 years of age, 49 underwent radical esophagectomy and 26 received dCRT. Survival was compared between the surgery and dCRT groups. Results: The mean ages of the surgery and chemoradiotherapy groups were 77.3 and 78.8 years, respectively. Differences in overall survival (OS) between the two groups were not statistically significant (3‐year OS: surgery 66.2%, dCRT 55.7%, p = 0.236). Multivariate analysis for OS showed a hazard ratio of 1.229 for dCRT versus surgery (90% confidence interval 0.681–2.217). OS did not differ between the groups in any of the performance statuses. For patients who were able to receive chemotherapy using fluorouracil and cisplatin, OS tended to be better in the surgery group, but the difference was not statistically significant (3‐year OS: surgery 68.1%, dCRT 51.8%, p = 0.117). Conclusions: There was no clear difference in survival outcome between surgery‐based therapy and dCRT as an initial treatment for esophageal cancer in older patients. Either treatment may be an option for older patients. [ABSTRACT FROM AUTHOR]

Background: Dieulafoy's lesion (DL) is a rare and important cause of acute nonvariceal upper gastrointestinal bleeding (ANVUGIB), however, there is a lack of clear guidelines focus on the endoscopic hemostasis treatment for DL. Sclerotherapy, as the ANVUGIB guideline recommended endoscopic hemostasis method, is widely used in clinical practice. The aim of this study is to investigate the efficacy of sclerotherapy as the initial treatment for Dieulafoy's lesion of the upper gastrointestinal tract (UDL). Methods: Patients with UDL who underwent the ANVUGIB standard endoscopic hemostasis between April 2007 and January 2023 were enrolled. The endoscopic therapy method was left to the discretion of the endoscopist. Results: In total, 219 patients were finally obtained, with 74 (33.8%) receiving sclerotherapy and 145 (66.2%) receiving other standard endoscopic therapy. The rebleeding within 30 days was significantly lower in the sclerotherapy group compared to the other standard group (5.8% vs. 16.8%, p = 0.047). There were no significant differences between the two groups in terms of successful hemostasis rate (93.2% vs. 94.5%, p = 0.713), median number of red blood cell transfusions (3.5 vs. 4.0 units, p = 0.257), median hospital stay (8.0 vs. 8.0 days, p = 0.103), transferred to ICU rate (8.1% vs. 6.2%, p = 0.598), the need for embolization or surgery rate (12.2% vs. 9.7%, p = 0.567) and 30-day mortality (0 vs. 2.1%, p = 0.553). In addition, we found no difference in efficacy between sclerotherapy alone and combination (3.1% vs. 8.1%, p = 0.714). Further analysis revealed that thermocoagulation for hemostasis was associated with a higher rate of rebleeding (28.6% vs. 3.1%, p = 0.042) and longer hospital stay (11.5 vs. 7.5 days, p = 0.005) compared to sclerotherapy alone. Conclusion: Sclerotherapy represents an effective endoscopic therapy for both alone and combined use in patients with upper gastrointestinal Dieulafoy's lesion. Therefore, sclerotherapy could be considered as initial treatment in patients with bleeding of UDL. [ABSTRACT FROM AUTHOR]

Background: New platforms for robotic surgery have recently become available for clinical use; however, information on the introduction of new surgical robotic platforms compared with the da Vinci™ surgical system is lacking. In this study, we retrospectively determined the safe introduction of the new "hinotori™" surgical robot in an institution with established da Vinci surgery using four representative digestive organ operations. Methods: Sixty-one patients underwent robotic esophageal, gastric, rectal, and pancreatic operations using the hinotori system in our department in 2023. Among these, 22 patients with McKeown esophagectomy, 12 with distal gastrectomy, 11 with high- and low-anterior resection of the rectum, and eight with distal pancreatectomy procedures performed by hinotori were compared with historical controls treated using da Vinci surgery. Results: The console (cockpit) operation time for distal gastrectomy and rectal surgery was shorter in the hinotori group compared with the da Vinci procedure, and there were no significant differences in the console times for the other two operations. Other surgical results were almost similar between the two robot surgical groups. Notably, the console times for hinotori surgeries showed no significant learning curves, determined by the cumulative sum method, for any of the operations, with similar values to the late phase of da Vinci surgery. Conclusions: This study suggests that no additional learning curve might be required to achieve proficient surgical outcomes using the new hinotori surgical robotic platform, compared with the established da Vinci surgery.

Background: The total number of resected lymph nodes (LNs) is an important determinant of longer survival after esophagectomy for esophageal squamous cell carcinoma (ESCC). However, the resected LN counts from areas that affect long-term outcomes remain unclear. Methods: This study included 406 patients who underwent minimally invasive esophagectomies (MIEs) at Kobe University Hospital. Resected LN counts were evaluated in the following areas: upper mediastinal (UM), middle mediastinal (MM), lower mediastinal (LM), and abdominal (Abd). Cut-off values for LN counts from each area were determined using receiver operating characteristics analysis of the survival status. Cox proportional hazards regression analyses were performed to identify prognostic factors. Results: The cut-off values for large or small numbers of resected LN counts in the UM, MM, LM, and Abd areas were 4, 8, 5, and 18, respectively, in patients with upper and middle thoracic (Ut/Mt) ESCC and 7, 6, 5, and 24, respectively, in patients with lower thoracic (Lt) ESCC. Multivariate analysis in patients with Ut/Mt ESCC revealed that tumor invasion depth, LN metastasis, and the resected LN count from the UM area were independent risk factors for overall survival [hazard ratio (HR), 7.04; 95% confidence interval (CI) 4.47–11.1; HR, 4.01; 95% CI 1.96–8.21; HR, 2.18; 95% CI 1.24–3.82, respectively]. In patients with Lt ESCC, tumor invasion depth, LN metastasis, and pulmonary complications were independent risk factors for overall survival (HR, 4.23; 95% CI 2.14–8.35; HR, 3.83; 95% CI 1.75–8.38; HR, 2.80; 95% CI 1.38–5.65, respectively). Resected LN counts from no areas were prognostic factors. Conclusion: The number of resected LNs from the UM area influenced the survival outcomes of patients with Ut/Mt ESCC after MIE.

Background: Minimally invasive esophagectomy is the first-line approach for esophageal cancer; however, there has recently been a paradigm shift toward robotic esophagectomy (RE). We investigated the clinical outcomes of patients who underwent RE compared with those of patients who underwent conventional minimally invasive thoracoscopic esophagectomy (TE) for locally advanced cT3 or cT4 esophageal cancer using a propensity-matched analysis. Methods: Overall, 342 patients with locally advanced cT3 or cT4 esophageal cancer underwent transthoracic esophagectomy with total mediastinal lymph node dissection between 2018 and 2022. The propensity-matched analysis was performed to assign the patients to either RE or TE by covariates of histological type, tumor location, and clinical N factor. Results: Overall, 87 patients were recruited in each of the RE and TE groups according to the propensity-matched analysis. The total complication rate and the rates of the three major complications (recurrent laryngeal nerve paralysis, anastomotic leakage, and pneumonia) were not significantly different between the RE and TE groups. However, the peak C-reactive protein concentration on postoperative day 3, rate of surgical site infection, and intensive care unit length of stay after surgery were significantly shorter in the RE group than in the TE group. No significant differences were observed in the harvested total and mediastinal lymph nodes. The total operation time was significantly longer in the RE group, while the thoracic operation time was shorter in the RE group than in the TE group. There was no significant difference between the two groups in the recurrence rate of oncological outcomes after surgery. Conclusion: RE may facilitate early recovery after esophagectomy with total mediastinal lymph node dissection and has the same technical feasibility and oncological outcomes as TE.

Background: This study aimed to evaluate the long-term survival outcomes of esophagectomy with off-pump coronary artery bypass grafting (OPCABG) vs. esophagectomy alone. Methods: A total of 1798 patients who received esophagectomy between January 2010 and February 2020 were included and divided into the 38 patients who underwent OPCABG followed by esophagectomy (OP + ES group) and 1760 patients had only esophagectomy (ES group). Propensity score matching (PSM) and Cox multivariable analyses were performed to compare postoperative complications, disease-free survival (DFS), and overall survival (OS) between the two groups. Results: There were 37 patients in the OP + ES group matched with 74 in the ES group. The matched OP + ES group had higher total postoperative complications than the ES group, especially more pulmonary infections (P = 0.001) and arrhythmias (P = 0.018), but no other postoperative complications were the difference. The DFS was similar and the OS was a significant difference between the matching 2 groups (log-rank, P = 0.132 and 0.04, respectively). Although pT 3/4 stage, pN (+), and tumor length > 3.0 cm were independently associated with worse OS and DFS in multivariable analysis, CAD and EF < 55% were also found to be a predictive factor for OS and DFS in univariate analysis. Conclusion: OPCABG followed by esophagectomy for esophageal cancer associated with coronary artery disease has equivalent DFS and recurrence pattern to esophagectomy for esophageal cancer alone, but with a disadvantage in OS.

Introduction: Reconstruction of a cloacal defect in a girl is often difficult and complicated.[1] This is most often done either by the sacro-perineal route or through the posterior sagittal route.[2] The procedures may involve total mobilization of the cloaca with or without the creation of a lower vagina with the help of a loop of vascularized bowel.[3] In our approach, such defects can be corrected using the lower anorectum for the creation of a lower vagina and abdominoperineal pull-through of the proximal divided bowel. This method can be used both in short and long common channel cloaca. Materials and Methods: We have used this procedure in one patient of posterior cloaca and four patients of anterior cloaca. These operations were done in patients of 1 year and 6 months to 4 years. Only one patient is waiting for the closure of the colostomy. Results: In all the cases, the urethra, the vagina, and the anus were successfully separated. Conclusion: This operation restores normal pelvic anatomy and physiology with minimal mutilation of the pelvic floor. [ABSTRACT FROM AUTHOR]

BACKGROUND: Esophagectomy in locally advanced esophageal adenocarcinoma is challenging and carries risk. The value of esophagectomy in locally advanced esophageal adenocarcinoma is not well-defined. STUDY DESIGN: The National Cancer Database was used to identify patients with cT4 esophageal adenocarcinoma from 2004 to 2020. Multivariable regression was used to identify factors associated with use of esophagectomy. Cox modeling was used to identify factors associated with all-cause mortality. Patients undergoing esophagectomy were 1:1 propensity score--matched to patients treated nonsurgically. Kaplan--Meier analysis was used to compare 5-year overall survival (OS). RESULTS: A total of 3,703 patients met inclusion criteria. Of those, 541 (15%) underwent esophagectomy, and 3,162 (85%) did not. Age 65 years or less (adjusted odds ratio [aOR] 1.69, 95% CI 1.33 to 2.14), White race (aOR 2.98, 95% CI 2.24 to 3.96), treatment in academic centers (aOR 1.64, 95% CI 1.33 to 2.02), private insurance (aOR 1.88, 95% CI 1.50 to 2.36), and tumors less than 6 cm (aOR 1.86, 95% CI 1.44 to 2.40) were associated with use of esophagectomy. Government of lack of insurance (hazard ratio [HR] 1.23, 95% CI 1.12 to 1.35), income <$46,000 (HR 1.11, 95% CI 1.03 to 1.20), treatment in nonacademic centers (HR 1.16, 95% CI 1.07 to 1.25), Charlson-Deyo Comorbidity Index 1 or more (HR 1.22, 95% CI 1.12 to 1.32), and tumors 6 cm or more (HR 1.20, 95% CI 1.09 to 1.32) were associated with risk of all-cause mortality. Esophagectomy (HR 0.50, 95% CI 0.44 to 0.56) and systemic therapy (HR 0.40, 95% CI 0.37 to 0.43) were associated with decreased risk of all-cause mortality. Patients undergoing esophagectomy had higher rates of 5-year OS (27.4% vs 13.2%, p < 0.0001) and longer median OS (24.71 vs 10.09 months, p < 0.0001). Among cT4b patients, those who underwent esophagectomy had higher rates of 5-year OS (24.5% vs 12.3%, p < 0.0001) and longer median OS (25.53 vs 11.01 months, p < 0.0001). CONCLUSIONS: In cT4 esophageal adenocarcinoma, esophagectomy is associated with improved rates of 5-year OS compared with nonsurgical treatment. [ABSTRACT FROM AUTHOR]

Background: The timing of trans-anal endorectal pull-through (TAEPT) for Hirschsprung's disease (HD) is controversial. Early endorectal pull-through avoids the occurrence of preoperative enterocolitis. However, delayed pull-through (≥ 31 days) enables postnatal maturation of the anal canal and sphincter complex. The aim of this study was to identify the best age to perform transanal pull-through according to the literature. Methods: This is a comprehensive systematic review. All articles published from 2010 to 2022 were searched in the Web of Science, Ovid Medline, PubMed, CINAHIL, and Embase databases, using the keywords HD, delayed or early treatment, trans-anal pull-through surgery, age, sex or gender, complications and outcomes. Articles that met the inclusion criteria with good to fair quality according to the Newcastle-Ottawa quality assessment and low bias score in the Cochran collaboration tool were reviewed. Results: Sixteen studies were eligible to be reviewed. The overall results of this study showed that due to more common shortterm complications at neonatal period and lower contrast enema diagnostic accuracy in determining the transition zone, it seems to be reasonable decision to postpone surgery until the child is several months old. There was also no difference in terms of complications and outcomes of trans-anal pull-through surgery between females and males. Conclusion: It is not recommended to delay surgery too much for ages over 1 year. Ages between 3 and 12 months can be a good time for interventional treatment for HD. [ABSTRACT FROM AUTHOR]

The article investigates physiotherapy practices after upper abdominal surgery. Topics discussed include the assessment and management strategies employed by physiotherapists, common interventions such as deep breathing exercises and mobility promotion, and the use of various outcome measures to monitor postoperative recovery.

Context: While lidocaine patches have been shown to be effective in ameliorating postoperative pain following procedures such as laparoscopic surgeries, midline incision gynecological surgery, and radical prostatectomy, their effectiveness is questionable in other conditions. Therefore, this review aimed to explore the pain-reducing efficacy of lidocaine patches in individuals undergoing surgery for gastrointestinal (GI) problems. Evidence Acquisition: A literature search was conducted using the following keywords and Boolean operators: ”[(digestive system surgical procedures [MeSH Terms]) OR abdominal surgery OR gastrointestinal surgical procedures) AND (postoperative pain), AND ((lidocaine [MeSH Terms]) OR lidocaine patch)]”. After reviewing the titles and abstracts, 5 studies were included in the review. Results: Three out of the 5 studies reviewed reported that lidocaine patches significantly reduced pain compared to control drugs and placebos. Another study reported a reduction in pain in lidocaine patch receivers, but this finding was statistically insignificant. All the studies reviewed reported a significant or marginally significant decrease in the use of opioids in lidocaine patch receivers. Conclusions: The effectiveness of lidocaine patches in alleviating postoperative pain is inconclusive. Considering the potential efficacy of lidocaine patches in reducing pain and the need for opioid use following abdominal surgeries, it seems necessary to conduct studies with larger sample sizes to clarify this issue.

Recent advancements in pediatric surgery have embraced telehealth (TH) modalities, transitioning from traditional in-person consultations to virtual care. This shift has broadened access to healthcare, potentially enhancing affordability, patient and caregiver satisfaction, and clinical outcomes. In pediatric colorectal surgery, telehealth has been effectively utilized to support Bowel Management Programs (BMPs) for children suffering from constipation and fecal incontinence. A systematic review was conducted to assess the effectiveness of virtual BMPs, analyzing studies from January 2010 to December 2023, sourced from MEDLINE (via PubMed), Embase, and the Cochrane Library, with five studies included. Remote BMPs, implemented through video or telephone consultations, reported satisfaction rates exceeding 75% among families, indicating a strong preference for virtual interactions over traditional visits. Significant findings from the studies include improvements in Vancouver and Baylor scores, reductions in the duration of multidisciplinary consultations, enhancements in pediatric quality of life and Cleveland scores, and decreased frequency of laxative treatments. The implementation of TH has facilitated patient-led care, enabling timely adjustments in treatment and efficient distribution of medical supplies. The findings suggest that virtual BMPs are a viable and effective alternative to conventional approaches, yielding high caregiver satisfaction and superior clinical outcomes while promoting patient independence.

Background: To determine the safety and efficacy of robot‐assisted minimally invasive esophagectomy (RAMIE) for locally advanced esophageal squamous cell carcinoma (ESCC) after neoadjuvant chemoimmunotherapy (NCI). Methods: Data from patients who underwent RAMIE between January 2020 and June 2022 were retrospectively analyzed. The oncological and operative outcomes of the NCI and surgery‐only (S) groups were compared by both unmatched and 1:1 propensity score‐matched (PSM) analysis. Results: A total of 201 patients with ESCC who underwent three‐incision RAMIE were included in this study (143 patients in the S group and 58 patients in the NCI group). Of the 58 patients who underwent NCI, a pathologically complete response (pCR) (ypT0N0) was identified in 14 (24.1%) patients. The patients in the NCI group were younger than those in the S group (p = 0.017), and had more advanced cT (p < 0.001) and cN stage diseases (p = 0.002). After 1:1 PSM of the confounders, 55 patients were allocated to each of the NCI and S groups. No significant differences were found in oncological and operative results, including surgical blood loss, operative time, and lymph node harvest (all p > 0.05). However, the NCI group exhibited a lower rate of pulmonary complications than the S group (3.6% vs. 14.5%, p = 0.047). No significant difference between the groups was found for other complications (all p > 0.05). Conclusion: These findings indicate that NCI could result in a high pCR rate without increased complications in locally advanced ESCC. RAMIE is safe and feasible in patients with ESCC after NCI.

Background: Oral nutritional supplements are one of the preferred methods of nutritional support for postoperative patients. This study aims to investigate the current status of oral nutritional supplements compliance in postoperative patients with digestive tract tumors and its influencing factors. Methods: Convenience sampling was employed to select 242 patients who underwent surgery for digestive tract tumors at a tertiary hospital in Shanghai from October 2022 to July 2023 as the study subjects. Data following a normal distribution were analyzed using independent sample t-tests, ANOVA single-factor analysis, Pearson correlation analysis, and multiple linear regression analysis to determine the factors influencing compliance with oral nutritional supplements. Results: A total of 252 questionnaires were distributed, with 10 invalid questionnaires excluded, resulting in an effective questionnaire rate of 96.03%. The compliance score for oral nutritional supplements in postoperative patients with digestive tract tumors was (2.40 ± 1.45), General Self-efficacy Scale (GSES) score was (24.72 ± 4.86), Multidimensional Scale of Perceived Social Support Scale (MSPSS) score was (58.67 ± 11.09), and Belief about Medicines Questionnaire Scale (BMQ) score was (0.17 ± 2.78). Multiple linear regression analysis revealed that age, adverse reactions, educational level, self-efficacy, medication beliefs, and social support were factors influencing compliance with oral nutritional supplements in postoperative patients with digestive tract tumors (P < 0.05). Conclusion: Our study revealed that the compliance to oral nutritional supplements among postoperative patients with digestive tract tumors was at a moderate level and was closely associated with age, educational level, adverse reactions to oral nutritional supplements, medication beliefs, social support, and self-efficacy. Nursing staff should conduct nursing assessments based on the specific circumstances of patients and their families, provide personalized health education management plans based on the patients' educational level, enhance patients' nutrition knowledge, improve patient self-efficacy, and enhance social support for patients, while further improving patient nutrition management.

Introduction: The introduction of the functional lumen imaging probe (FLIP) has provided objective, real-time feedback on the geometric variations with each component of a hiatal hernia repair (HHR). The utility of this technology in altering intraoperative decision-making has been scarcely reported. Herein, we report a single-center series of intraoperative FLIP during HHR. Methods: A retrospective review of electronic medical records between 2020 and 2022 was conducted and all patients undergoing non-recurrent HHR with FLIP were queried. Patient and hernia characteristics, intraoperative FLIP values and changes in decision-making, as well as early post-operative outcomes were reported. Both diameter and distensibility index (DI) were measured at 40 ml and 50 ml balloon inflation after hiatal dissection, after hiatal closure, and after fundoplication when indicated. Results: Thirty-three patients met inclusion criteria. Mean age was 62 ± 14 years and mean BMI was 28 ± 6 kg/m2. The majority (53%) were type I hiatal hernias. The largest drop in DI occurred after hiatal closure, with minimal change seen after fundoplication (mean DI of 4.3 ± 2. after completion of HH dissection, vs 2.7 ± 1.2 after hiatal closure and 2.3 ± 1 after fundoplication when performed). In 13 (39%) of cases, FLIP values directly impacted intraoperative decision-making. Fundoplication was deferred in 4/13 (31%) patients, the wrap was loosened in 2/13 (15%); the type of fundoplication was altered to achieve adequate anti-reflux values in 2/13 (15%) patients, and in 1/13 (3%) the wrap was tightened. Conclusion: FLIP measurements can be used intraoperatively to guide decision-making and alter management plan based on objective values. Long-term outcomes and further prospective studies are required to better delineate the value of this technology. [ABSTRACT FROM AUTHOR]

Background: Minimally invasive surgery (MIS), such as laparoscopic and robotic surgery for rectal cancer, is performed worldwide. However, limited information is available on the advantages of MIS over open surgery for multivisceral resection for cases clinically invading adjacent organs. Patients and methods: This was a retrospective propensity score-matching study of consecutive clinical T4b rectal cancer patients who underwent curative intent surgery between 2006 and 2021 at the University of Tokyo Hospital. Results: Sixty-nine patients who underwent multivisceral resection were analyzed. Thirty-three patients underwent MIS (the MIS group), while 36 underwent open surgery (the open group). Twenty-three patients were matched to each group. Conversion was required in 2 patients who underwent MIS (8.7%). R0 resection was achieved in 87.0% and 91.3% of patients in the MIS and open groups, respectively. The MIS group had significantly less blood loss (170 vs. 1130 mL; p < 0.0001), fewer Clavien–Dindo grade ≥ 2 postoperative complications (30.4% vs. 65.2%; p = 0.0170), and a shorter postoperative hospital stay (20 vs. 26 days; p = 0.0269) than the open group. The 3-year cancer-specific survival rate, relapse-free survival rate, and cumulative incidence of local recurrence were 75.7, 35.9, and 13.9%, respectively, in the MIS group and 84.5, 45.4, and 27.1%, respectively, in the open group, which were not significantly different (p = 0.8462, 0.4344, and 0.2976, respectively). Conclusion: MIS had several short-term advantages over open surgery, such as lower complication rates, faster recovery, and a shorter hospital stay, in rectal cancer patients who underwent multivisceral resection.

Background: We aimed to study the impact of operative time on textbook outcome (TO), especially postoperative complications and length of postoperative stay in minimally invasive esophagectomy. Methods: Patients undergoing esophagectomy for curative intent within a prospectively maintained database from 2016 to 2022 were retrieved. Relationships between operative time and outcomes were quantified using multivariable mixed-effects models with medical teams random effects. A restricted cubic spline (RCS) plotting was used to characterize correlation between operative time and the odds for achieving TO. Results: Data of 2210 patients were examined. Median operative time was 270 mins (interquartile range, 233–313) for all cases. Overall, 902 patients (40.8%) achieved TO. Among non-TO patients, 226 patients (10.2%) had a major complication (grade ≥ III), 433 patients (19.6%) stayed postoperatively longer than 14 days. Multivariable analysis revealed operative time was associated with higher odds of major complications (odds ratio 1.005, P < 0.001) and prolonged postoperative stay (≥ 14 days) (odds ratio 1.003, P = 0.006). The relationship between operative time and TO exhibited an inverse-U shape, with 298 mins identified as the tipping point for the highest odds of achieving TO. Conclusions: Longer operative time displayed an adverse influence on postoperative morbidity and increased lengths of postoperative stay. In the present study, the TO displayed an inverse U-shaped correlation with operative time, with a significant peak at 298 mins. Potential factors contributing to prolonged operative time may potentiate targets for quality metrics and risk-adjustment process. [ABSTRACT FROM AUTHOR]

Background: Appendicitis is an extremely common disease with a variety of medical and surgical treatment approaches. A multidisciplinary expert panel was convened to develop evidence-based recommendations to support clinicians and patients in decisions regarding the diagnosis and treatment of appendicitis. Methods: A systematic review was conducted from 2010 to 2022 to answer 8 key questions relating to the diagnosis of appendicitis, operative or nonoperative management, and specific technical and post-operative issues for appendectomy. The results of this systematic review were then presented to a panel of adult and pediatric surgeons. Evidence-based recommendations were formulated using the GRADE methodology by subject experts. Results: Conditional recommendations were made in favor of uncomplicated and complicated appendicitis being managed operatively, either delayed (>12h) or immediate operation (<12h), either suction and lavage or suction alone, no routine drain placement, treatment with short-term antibiotics postoperatively for complicated appendicitis, and complicated appendicitis previously treated nonoperatively undergoing interval appendectomy. A conditional recommendation signals that the benefits of adhering to a recommendation probably outweigh the harms although it does also indicate uncertainty. Conclusions: These recommendations should provide guidance with regard to current controversies in appendicitis. The panel also highlighted future research opportunities where the evidence base can be strengthened. [ABSTRACT FROM AUTHOR]

Extraosseous Ewing's sarcoma is an extremely rare tumor. In the literature, intestinal Ewing's sarcoma was reported in 20 cases, and omental Ewing's sarcoma was reported in only two cases. In this case report, we report a 23-year-old female who presented with the complaint of diffuse abdominal pain. Abdominal ultrasound and whole-body computed tomography revealed a mass starting from the adnexal area and extending between the intestinal loops. Serum levels of tumor markers were high. The serum levels of carbohydrate antigen-125 (CA-125) and carcinoembryonic antigen-19.9 (CA-19.9) were high (427.5 U/mL and 67.9 U/mL, respectively). Laparotomic exploration was performed with the preliminary diagnosis of an adnexal mass, and a mass originating from the small intestine meso and completely covered by the omentum was excised. Histological evaluation reported intestinal and omental origin of Ewing's sarcoma. This case highlights the importance of rare extraosseous Ewing's sarcoma, which should be included in the differential diagnosis of a young female with intra-abdominal mass. [ABSTRACT FROM AUTHOR]

BACKGROUND: Owing to advances in the multidisciplinary treatment of hepatocellular carcinoma (HCC), a conceptualization and definition for borderline resectable (BR) HCC, which carries a high risk of recurrence, is warranted. In this study, we aimed to define BR-HCC using a prognosis-oriented approach. STUDY DESIGN: The study included an original cohort of 221 patients and an independent validation cohort of 181 patients who had undergone primary hepatic resection for HCC. To define biological BR-HCC, we evaluated the risk factors for early recurrence beyond the Milan criteria within 1 year after hepatic resection using multivariable logistic regression models. Subsequently, we developed high-risk scores using the identified risk factors and defined BR-HCC. The utility of high-risk score was validated in the validation cohort. RESULTS: In the original cohort (hepatitis B virus:hepatitis C virus = 20%:29%), recurrence beyond the Milan criteria within 1 year was observed in 28 patients (13%), with a 5-year survival rate of 25%. Multivariable analysis identified risk factors for recurrence beyond the Milan criteria within 1 year, including serum alpha-fetoprotein levels of 12 ng/mL or more (p = 0.02), tumor diameters less than 5 cm (p = 0.02), tumor number 3 or more (p = 0.001), and macrovascular invasion (p = 0.04). BR-HCC was defined as a tumor with 2 or more identified risk factors, and 42 patients (19%) were diagnosed with BR-HCC, with a 5-year survival rate of 51%. In the validation cohort, 45 (25%) patients had BR-HCC, with a 5-year survival rate of 42%. CONCLUSIONS: The prognosis-oriented definition of BR-HCC enabled us to identify patients who are susceptible to early unresectable recurrence and have poor survival after hepatic resection for HCC. For patients with BR-HCC, preoperative systemic therapy may be a viable option to improve postresection outcomes. [ABSTRACT FROM AUTHOR]

Objective: Perioperative Neurocognitive Disorders (PND) is a common neurological complication after radical colorectal cancer surgery, which increases adverse outcomes. So, our objective is to explore the influence of dexmedetomidine added to ropivacaine for transversus abdominis plane block (TAPB) on perioperative neurocognitive disorders, and to provide a new way to reduce the incidence of PND. Methods: One hundred and eighty patients submitted to radical laparoscopic colorectal cancer surgery were randomly divided into Control group and Dex group. Ultrasound guided TAPB was performed after anesthesia induction: 0.5% ropivacaine 20 ml was injected into each transversus abdominis plane in Control group, 0.5% ropivacaine + 1 μg/kg dexmedetomidine (amounting to 20 ml) in Dex group. We observed the incidence of PND within 30 days after surgery. Results: One hundred and sixty-nine cases were finally analyzed, including 84 cases in Control group and 85 cases in Dex group. Compared with Control group, there was no significant difference in terms of the incidence of PND on the 3rd day and the 7th day (P > 0.05), but the incidence significantly decreased at the 6th hour, at the 24th hour and on the 30th day after surgery (P < 0.05) in Dex group. Conclusion: Dexmedetomidine added to ropivacaine for TAPB can reduce the incidence of PND in the first 24 h after surgery and on the 30th postoperative day, which may be related to reduce the consumption of general anesthetics and provide satisfactory postoperative analgesia.

The presence of positive bile culture during intraoperative procedures has been associated with elevated morbidity and mortality rates in hepatobiliopancreatic surgeries, contributing to increased healthcare expenditures. However, the precise impact of bactobilia on the development of postoperative complications remains uncertain due to existing disparities in the published literature. In this retrospective cohort study, we assessed 137 patients who underwent major hepatobiliopancreatic surgery to examine the relationship between intraoperative bile culture outcomes and subsequent postoperative infectious complications. Among patients with bactobilia, a significant 35.1% exhibited systemic or local infectious complications, whereas only 11.1% of those with negative culture results experienced any infectious complications (p = 0.002). Similarly, a notable difference was observed in the incidence of surgical site infections, with 24.3% in the bactobilia group compared to 7.9% in the negative culture group (p = 0.01). A total of 74 monomicrobial cultures with microbiological growth were isolated, predominantly featuring Gram-negative microorganisms, primarily Enterobacteriaceae in 49 cultures. Escherichia coli was identified in 37.8% of positive cultures, while Klebsiella pneumoniae was evident in 21.6%. Gram-positive microorganisms were present in 10 cultures, with Enterococcus emerging as the prevailing species. The logistic regression model identified a positive bile culture as an independent factor significantly associated with infection development (OR: 2.26; 95% confidence interval: 1.23-11; p = 0.02). Considering the limitations of the study, these findings underscore the critical importance of conducting bile cultures during the intraoperative phase to enable vigilant monitoring and prompt management of infectious complications.

Introduction: Curative esophagectomy is not always possible in patients with locally advanced esophageal cancer. However, few studies have investigated patients who underwent non-curative surgery with intraoperative judgment. This study aimed to investigate patient characteristics and clinical outcomes for patients undergoing non-curative surgery and compare them between non-resectional and non-radical surgery. Methods: Among 989 consecutive patients with thoracic esophageal squamous cell carcinoma who were preoperatively expected for curative esophagectomy, 66 who were eligible for non-curative surgery were included in this study. Results: Intraoperative diagnosis of T4b accounted for 93% of the reasons for the failure of curative surgery. In those patients, esophageal cancer locally invaded into the aortobronchial constriction (70%), trachea (25%), or pulmonary vein (5%). Lymph node metastasis mainly invaded into the trachea (50%) or bronchus (28%). The overall survival of patients with non-curative surgery was 51.5%, 25.7%, and 10.4% at 6, 12, and 24 months after surgery, respectively. Although there were no differences in preoperative patient characteristics between non-resectional and non-radical surgery, distant metastasis, especially pleural dissemination, was significantly observed in T4b patients due to esophageal cancer with non-radical surgery than those with non-resectional surgery (35% vs. 15%, p = 0.002). Even in patients with non-curative surgery, R1 resection and postoperative chemoradiotherapy were identified as independent factors for survival 1 year after surgery (p = 0.047, and 0.019). Conclusions: T4b tumor located in aortobronchial constriction or trachea/bronchus makes it difficult to diagnose whether it is resectable or unresectable. Moreover, surgical procedures and perioperative treatment were deeply associated with the clinical outcomes. [ABSTRACT FROM AUTHOR]

The principal mechanisms surrounding gastrointestinal (GI) side effects due to chemotherapy are unclear, whereas the information regarding symptom management of patients with esophageal cancer post-esophagectomy is lacking. Esophagectomy patients are left with significant anatomical changes to the GI tract, including the cutting of the vagus nerve, which regulates gastric secretions, gastric acid pH, and motility. A 76-year-old male patient self-referred himself to the clinical dietitian for nutritional management of chronic nausea, fatigue, weight loss, and dumping syndrome 9 months post-esophagectomy, which was not responsive to medications. A physical functional nutritional assessment with evaluation of diet history and elimination suggested gastric hypochlorhydria. Gastric acid is needed for the active absorption of iron, zinc, B complex vitamins, especially B12, and digestion of consumed proteins. A digestive supplement, betaine hydrochloric acid with pepsin (BHClP), was introduced, and the patient ingested 1 capsule containing 500 mg betaine hydrochloride and 23.5 mg pepsin prior to protein-containing meals and reported a substantial decrease in GI symptoms while eating a regular diet with no limitations. He gained necessary weight and energy for daily activities. After a few months, the patient discontinued BHClP, and GI symptoms and dumping syndrome returned, leading to a loss of 7.5% of his body weight. The patient reinitiated the supplement and GI symptoms dissipated, and weight was restored. BHClP provided metabolic therapeutic benefit to optimize the patient's oral intake, preventing further complications and malnutrition. The success with BHClP for this patient case suggests that more research is needed to fully realize the mechanisms and clinical usage. [ABSTRACT FROM AUTHOR]

Background: The use of hemostatic agents by general surgeons during abdominal operations is commonplace as an adjunctive measure to minimize risks of postoperative bleeding and its downstream complications. Proper selection of products can be hampered by marginal understanding of their pharmacokinetics and pharmacodynamics. While a variety of hemostatic agents are currently available on the market, the choice of those products is often confusing for surgeons. This paper aims to summarize and compare the available hemostatic products for each clinical indication and to ultimately better guide surgeons in the selection and proper use of hemostatic agents in daily clinical practice. Methods: We utilized PubMed electronic database and published product information from the respective pharmaceutical companies to collect information on the characteristics of the hemostatic products. Results: All commercially available hemostatic agents in the US are described with a description of their mechanism of action, indications, contraindications, circumstances in which they are best utilized, and expected results. Conclusion: Hemostatic products come with many different types and specifications. They are valuable tools to serve as an adjunct to surgical hemostasis. Proper education and knowledge of their characteristics are important for the selection of the right agent and optimal utilization. [ABSTRACT FROM AUTHOR]

Simple Summary: The advancement of multidisciplinary treatment has increased the need to develop a test to monitor tumor burden during treatment. We herein analyzed urinary microRNAs within extracellular vesicles from patients with esophageal squamous cell carcinoma (ESCC) and normal individuals using a microarray, and identified 18 microRNAs which were significantly expressed in ESCC patients. Background: The advancement of multidisciplinary treatment has increased the need to develop tests to monitor tumor burden during treatment. We herein analyzed urinary microRNAs within extracellular vesicles from patients with esophageal squamous cell carcinoma (ESCC) and normal individuals using a microarray. Methods: Patients with advanced ESCC who underwent esophagectomy (A), endoscopic submucosal resection (ESD) (B), and healthy donors (C) were included. Based on microRNA expression among the groups (Analysis 1), microRNAs with significant differences between groups A and C were selected (Analysis 2). Of these candidates, microRNAs in which the change between A and C was consistent with the change between B and C were selected for downstream analysis (Analysis 3). Finally, microRNA expression was validated in patients with recurrence from A (exploratory analysis). Results: For analysis 1, 205 microRNAs were selected. For Analyses 2 and 3, the changes in 18 microRNAs were consistent with changes in tumor burden as determined by clinical imaging and pathological findings. The AUC for the detection of ESCC using 18 microRNAs was 0.72. In exploratory analysis, three of eighteen microRNAs exhibited a concordant trend with recurrence. Conclusions: The current study identified the urinary microRNAs which were significantly expressed in ESCC patients. Validation study is warranted to evaluate whether these microRNAs could reflect tumor burden during multidisciplinary treatment for ESCC. [ABSTRACT FROM AUTHOR]

Background: Few reviews have addressed delirium prevention among intermediate to high‐risk older surgical patients. Aims: To map preoperative delirium prevention interventions for older surgical patients at intermediate to high risk of developing delirium, assess outcomes and identify gaps in knowledge. Design: Systematic narrative review of randomised controlled trials reported following the PRISMA checklist. Methods: A systematic search was conducted of the literature published from 1990 to October 2022 in Medline, CINAHL and Ageline and of the grey literature in Google Scholar. Randomised controlled trials were retrieved that assessed the effectiveness of preoperative delirium prevention interventions for older surgical patients at intermediate to high risk of delirium. Data were extracted using a data extraction tool, and results were tabulated. Studies were assessed for bias using the Cochrane Collaboration Risk of Bias tool. Results: Twenty‐one studies met the selection criteria including N = 5096 participants. Two studies tested cognitive training, two studies tested fascia iliaca compartment block and one study assessed femoral nerve block. Ten studies tested prophylactic medications including methylprednisolone. Five studies investigated geriatric assessment and management. One study assessed transcutaneous electrical acupoint stimulation. In the two studies testing fascia iliaca compartment block, there was a reduction in postoperative delirium for orthopaedic patients. Methylprednisolone reduced postoperative delirium in orthopaedic patients and in those undergoing gastrointestinal surgery. Results of all other interventions on the occurrence of postoperative delirium and additional outcomes including the severity and duration of delirium were inconclusive. Conclusions: Despite the promising results for fascia iliaca compartment block and methylprednisolone, there is limited knowledge regarding evidence‐based delirium prevention interventions. Most studies had small sample sizes indicating that the current evidence is exploratory. There is an urgent need for the funding and conduct of trials to test preventative interventions for older surgical patients at intermediate to high risk of developing delirium.

Background: Neoadjuvant chemoimmunotherapy (NCIT) for locally advanced esophageal squamous cell carcinoma (ESCC) is supported by increasing data, but the sample size is limited, and the findings are not completely consistent. We conducted a real‐world study and a meta‐analysis to evaluate the efficacy and safety of NCIT in locally advanced ESCC. Methods: We retrospectively assessed the outcomes of patients with locally advanced ESCC who completed NICT and subsequent esophagectomy at our hospital between January 2019 and December 2022, including pathological complete response (pCR) rate, major pathological response (MPR) rate, 1‐, 2‐, and 3‐year overall survival (OS) rates, disease control rate (DCR), objective response rate (ORR), 1‐year recurrence rate, R0 resection rate and adverse events. Moreover, a meta‐analysis of 27 published literatures was also conducted for comparison. Results: In the analysis, 128 patients were studied, with 25% achieving pCR, 46.1% MPR, and 99.2% R0 resection. The 1‐, 2‐, and 3‐year OS rates were 91.41% (95% CI: 85.15%–95.63%), 75.00% (95% CI: 66.58%–82.23%) and 64.84% (95% CI: 55.91%–73.07%).ORR and DCR were 31.2% (95% CI: 23.31–39.99) and 64.1% (95% CI: 55.15%–72.38%), and the 1‐year recurrence rate was 26.7% (95% CI: 22.5%–38.1%). Treatment‐related events occurred in 96.1% but were acceptable. In a meta‐analysis of 27 studies with 1734 patients, pooled rates for pCR, MPR, ORR, DCR, and R0 resection were 29%, 52%, 71%, 97%, and 98%, respectively, with a 1‐year recurrence rate of 12%. Conclusion: NCIT is safe and provides potential survival benefits for patients with locally advanced ESCC. However, randomized phase 3 trial data is still needed. [ABSTRACT FROM AUTHOR]

Gastroesophageal reflux disease (GERD) is a chronic disorder characterized by the reflux of gastric contents into the esophagus, leading to symptoms and potential long-term complications such as Barrett esophagus and esophageal adenocarcinoma. Currently, there are various medical, endoscopic, and surgical therapeutic strategies for GERD. However, proton pump inhibitors (PPIs), which effectively suppress acid secretion but require daily administration, remain the mainstay of treatment. Noncontinuous therapy for GERD includes on-demand and different variations of intermittent administration of antireflux medication. Attributes that make an antireflux medication a good candidate for noncontinuous therapy for GERD include potent acid suppression, rapid effect, durability of antisecretory effect, and flexibility of administration. Noncontinuous therapy for GERD is appealing to patients because it is convenient, reduces cost, and alleviates concerns about complications of long-term PPI use. Patients with nonerosive esophageal reflux disease or low-grade erosive esophagitis who have episodic heartburn are probably best suited for such treatment. Although PPIs have been shown to be efficacious as on-demand or intermittent therapy for GERD, their usefulness as on-demand treatment for episodic heartburn has been limited by their slow maximal effect on intragastric acid secretion. In contrast, potassium-competitive acid blockers (P-CABs) demonstrate the pharmacokinetic and pharmacodynamic characteristics that make this class of drugs a good candidate for noncontinuous treatment of GERD. Early studies using P-CABs for noncontinuous treatment of GERD have demonstrated promising results. Future studies are needed to further establish the value of P-CABs for such a therapeutic approach. This article reviews the current evidence on the use of PPIs and P-CABs in noncontinuous therapy for GERD. [ABSTRACT FROM AUTHOR]

Background: Literature suggests colonic resection and primary anastomosis (RPA) instead of Hartmann's procedure (HP) for the treatment of left-sided colonic emergencies. We aim to evaluate the surgical options globally used to treat patients with acute left-sided colonic emergencies and the factors that leading to the choice of treatment, comparing HP and RPA. Methods: This is a prospective, international, multicenter, observational study registered on ClinicalTrials.gov. A total 1215 patients with left-sided colonic emergencies who required surgery were included from 204 centers during the period of March 1, 2020, to May 31, 2020. with a 1-year follow-up. Results: 564 patients (43.1%) were females. The mean age was 65.9 ± 15.6 years. HP was performed in 697 (57.3%) patients and RPA in 384 (31.6%) cases. Complicated acute diverticulitis was the most common cause of left-sided colonic emergencies (40.2%), followed by colorectal malignancy (36.6%). Severe complications (Clavien-Dindo ≥ 3b) were higher in the HP group (P < 0.001). 30-day mortality was higher in HP patients (13.7%), especially in case of bowel perforation and diffused peritonitis. 1-year follow-up showed no differences on ostomy reversal rate between HP and RPA. (P = 0.127). A backward likelihood logistic regression model showed that RPA was preferred in younger patients, having low ASA score (≤ 3), in case of large bowel obstruction, absence of colonic ischemia, longer time from admission to surgery, operating early at the day working hours, by a surgeon who performed more than 50 colorectal resections. Conclusions: After 100 years since the first Hartmann's procedure, HP remains the most common treatment for left-sided colorectal emergencies. Treatment's choice depends on patient characteristics, the time of surgery and the experience of the surgeon. RPA should be considered as the gold standard for surgery, with HP being an exception.

Simple Summary: After esophageal resection for cancer, severe postoperative complications (SPCs) have been reported in up to 20% of patients. These are associated with prolonged hospital stay, augmented costs, need for supplementary treatments, and increased 90-day mortality. The global effect of SPCs on long-term survival after esophagectomy is discussed, whereas, in the current literature, it is not frequently covered. The present systematic review and individual patient data meta-analysis suggests a statistically significant detrimental effect of SPCs on 5-year overall survival in patients undergoing curative esophagectomy for cancer. Also, a clinical trend toward reduced 5-year cancer specific survival and disease-free survival was perceived. Background. Severe postoperative complications (SPCs) may occur after curative esophagectomy for cancer and are associated with prolonged hospital stay, augmented costs, and increased in-hospital mortality. However, the effect of SPCs on survival after esophagectomy is uncertain. Aim. To assess the impact of severe postoperative complications (SPCs) on long-term survival following curative esophagectomy for cancer, we conducted a systematic search of PubMed, MEDLINE, Scopus, and Web of Science databases up to December 2023. The included studies examined the relationship between SPCs and survival outcomes, defining SPCs as Clavien–Dindo grade > 3. The primary outcome measure was long-term overall survival (OS). We used restricted mean survival time difference (RMSTD) and 95% confidence intervals (CIs) to calculate pooled effect sizes. Additionally, we applied the GRADE methodology to evaluate the certainty of the evidence. Results. Ten studies (2181 patients) were included. SPCs were reported in 651 (29.8%) patients. The RMSTD overall survival analysis shows that at 60-month follow-up, patients experiencing SPCs lived for 8.6 months (95% Cis −12.5, −4.7; p < 0.001) less, on average, compared with no-SPC patients. No differences were found for 60-month follow-up disease-free survival (−4.6 months, 95% CIs −11.9, 1.9; p = 0.17) and cancer-specific survival (−6.8 months, 95% CIs −11.9, 1.7; p = 0.21). The GRADE certainty of this evidence ranged from low to very low. Conclusions. This study suggests a statistically significant detrimental effect of SPCs on OS in patients undergoing curative esophagectomy for cancer. Also, a clinical trend toward reduced CSS and DFS was perceived. [ABSTRACT FROM AUTHOR]
