: Religious fasting in patients after Metabolic and Bariatric Surgery (MBS) remains a topic with limited clarity. This study aims to present the results of a survey on religious fasting in patients after MBS in Israel. The questionnaire was sent to members of the Israeli Society for Metabolic and Bariatric Surgery (ISMBS).
View Article and Find Full Text PDFIntroduction: One anastomosis gastric bypass (OAGB) is a common procedure associated with satisfactory outcomes. Revisional surgery due to weight regain or insufficient weight loss (WR/IWL) after OAGB is underreported.
Methods: A retrospective analysis of a single-bariatric surgeon database was conducted.
Background: Vegetarianism is constantly increasing worldwide. However, the role of metabolic and bariatric surgery (MBS) in vegetarians/vegans is unclear as there is very limited data on this topic. The aim of this study was to evaluate MBS outcomes in vegetarians or vegans.

- - Gastroesophageal reflux disease (GERD) is prevalent among severely obese patients, and its impact post-sleeve gastrectomy (SG) is uncertain, leading some surgeons to view GERD as a reason to avoid SG.
- - A study analyzed data from patients with preoperative GERD who had SG, finding that 5.8% of patients diagnosed with GERD had follow-up results, with most (78.1%) still experiencing GERD symptoms after surgery.
- - The findings showed that better GERD-related quality of life (GERD-HRQL) scores were linked to lower baseline Body Mass Index (BMI), lower smoking rates, and greater total weight loss post-surgery, suggesting that smoking cessation
Background: Failed sleeve gastrectomy (SG), defined by inadequate weight loss or weight regain and by reflux and structural complications, can be treated by a laparoscopic conversion to Roux-en-Y gastric bypass (RYGB).
Objectives: To examine the efficacy and outcomes of conversion surgery over a 14-year follow-up period.
Setting: Government and private medical centers in university settings.
Article Synopsis
- The study investigates the outcomes of patients who had One-anastomosis Gastric Bypass (OAGB) revisions due to marginal ulcer (MU) perforations over a span of two years.
- Out of 22 patients analyzed, the majority were men, with a significant portion being smokers, and the most common surgical intervention was the omental patch.
- At a median follow-up of 48 months, the recurrence rate of MU was 14%, indicating that while MU perforation is a chronic issue, the revision procedures were generally effective.
Article Synopsis
- Bariatric and metabolic surgery (BMS) is an effective option for treating severe obesity, particularly in patients with a BMI of 50 kg/m or higher.
- A study analyzed 263 patients who underwent BMS, comparing outcomes between primary surgeries and revisional surgeries; the results showed that revisional patients had higher leak rates and longer hospital stays.
- The mortality rate was low at 1.1% for both groups, but more research is needed to determine the best surgical techniques for patients with extremely high BMI.
Revisional Bariatric Surgery (RBS) is increasing in popularity. Elderly patients (> 65 years old) are sometimes referred for RBS evaluation. The aim of this study is to evaluate outcomes of elderly patients undergoing RBS.
View Article and Find Full Text PDFBackground: One anastomosis gastric bypass (OAGB) is gaining popularity worldwide due to its safety and effectiveness. OAGB is the most commonly performed metabolic bariatric surgery (MBS) in Israel. Israel is the only country where OAGB is the most prevalent MBS.
View Article and Find Full Text PDFBackground: Idiopathic Intracranial Hypertension (IIH) is a rare disorder, linked to severe obesity. The study aimed to evaluate long-term effects of metabolic and bariatric surgery (MBS) on IIH outcomes.
Methods: Retrospective study of patients with IIH and severe obesity who underwent MBS.
Background: Bariatric surgery (BS) is the optimal approach for sustained weight loss and may alter donation candidacy in potential donors with obesity. We evaluated the long-term effects of nephrectomy after BS on metabolic profile, including body mass index, serum lipids and diabetes, and kidney function of donors.
Methods: This was a single-center retrospective study.
Purpose: Assess the subjective impact of gastro-esophageal reflux disease (GERD) symptoms on patients undergoing revision from laparoscopic sleeve gastrectomy (LSG) to one-anastomosis gastric bypass (OAGB) using the Reflux Disease Questionnaire for GERD (RDQ) and the GERD-health related quality of life score (GERD-HRQL), prior to- and following conversion.
Methods: Patients undergoing revision from LSG to OAGB were prospectively followed between May 2015 and December 2020. Data retrieved included demographics, anthropometrics, previous bariatric history, time interval between LSG and OAGB, weight loss, and co-morbidities.
Purpose: Laparoscopic sleeve gastrectomy (SG) is the most popular bariatric surgery. Nonetheless, only a few studies have reported its long-term outcomes. This study aimed to evaluate changes in weight and body mass index (BMI) parameters, resolution of comorbidities, and frequency of re-operations in a follow-up period of at least 10 years.

Aim: Examine the feasibility and effectiveness of an instructor approach to teaching residents how to perform laparoscopic eTEP independently following a dedicated course of individual teaching.
Methods: Prospective analysis of eTEP procedures performed by residents between March 2018 and September 2020.
Article Synopsis
- The study investigates the safety and effectiveness of bariatric surgery, specifically Roux-en-Y gastric bypass and sleeve gastrectomy, for morbidly obese patients undergoing liver transplantation.
- Eighteen patients were analyzed, showing significant weight loss averages of 31% total and 81% excess weight, with improvements in diabetes management for some.
- Although bariatric surgery proved beneficial for addressing obesity in patients with liver issues, the associated surgical risks were noted to be higher than in typical bariatric surgery scenarios.
Background: Staple-line leaks (SLL) after sleeve gastrectomy (SG) are a rare but serious complication requiring radiologic and endoscopic interventions with varying degrees of success. When failed, a chronic gastrocutaneous fistula forms with decreasing chances of closure with time. Definitive surgical management of chronic SLL after SG include laparoscopic revision to total/subtotal gastrectomy (LTG/LSTG) or a fistulo-jejunostomy (LRYFJ), both with Roux-en-Y reconstruction.

Weight-related outcomes for underweight youth were also examined.
View Article and Find Full Text PDFBackground And Aims: Longitudinal assessment of body composition following bariatric surgery allows monitoring of health status. Our aim was to elucidate trends of anthropometric and clinical outcomes 3 years following sleeve gastrectomy (SG).
Methods: A prospective cohort study of 60 patients who underwent SG.
Background: The surgical risk of morbidly obese patients is high and even higher for kidney transplant candidates. A BMI > 35-40 kg/m is often a contraindication for that surgery. The safety, feasibility, and outcome of bariatric surgery for those patients are inconclusive.
View Article and Find Full Text PDFBackground: Data on the benefits of bariatric surgery for morbid obesity among kidney transplant recipients are scarce.
Objective: To examine the effect of bariatric surgery on graft function and survival and on obesity-related co-morbidities.
Setting: University hospital.
Background: The endocannabinoid (eCB) system plays a key role in the development of obesity and its comorbidities. Limited information exists on the changes in circulating eCBs following bariatric surgery.
Objectives: This study aims to (i) assess the circulating levels of eCBs and related molecules and (ii) examine the association between their levels and numerous clinical/metabolic features pre- and post-operatively.
The effect of bariatric surgery on hypothyroidism: Sleeve gastrectomy versus gastric bypass.

September 2018
Background: Hypothyroidism is prevalent in morbidly obese patients and may improve after a weight reduction surgery.
Objectives: Laboratory and clinical changes in hypothyroid patients undergoing laparoscopic sleeve gastrectomy (LSG) or laparoscopic Roux-en-Y gastric bypass (LRYGB) were compared and evaluated.
Settings: Data were retrieved from a prospectively collected database of 2 public bariatric units.
