Objectives: Laparoscopic adjustable gastric banding (LAGB) was once a preferred method of obesity treatment featuring a straightforward technique, removability, and good early results. In a significant proportion of patients, however, it was not a durable weight-loss procedure and has been associated with a high longer-term complication rate. The purpose of this study was to directly compare the results of conversion to laparoscopic Roux-en-Y gastric bypass (LRYGB) and laparoscopic sleeve gastrectomy (LSG) after failed LAGB.
Methods: Post-LAGB complications and weight outcomes of conversion (absolute weight, excess weight loss [%EWL], total weight loss [%TWL]) to LSG vs LRYGB were retrospectively reviewed and statistically compared using Fisher's exact test and the independent samples t test.
Results: Over a 6-year period, 74/272 (27.2%) morbidly obese LAGB patients experienced marked complications requiring band removal. Forty-nine of these patients underwent conversion by LRYGB (n = 29) or LSG (n = 20). There was no statistically significant difference in complication rates between converted procedures and no significant difference in respective EWL and TWL (6-month EWL: LRYGB, 53.6% vs LSG, 51.3% and respective TWL, 22.8 vs 21.3%; 12-month EWL, 70.1 vs 56.1%; and TWL, 30.7 vs 23.2%; p > 0.05). All conversion patients were present at each time point.
Conclusions: Outcomes for LSG vs LRYGB following failed LAGB were equally safe and effective.

Placement of a laparoscopic adjustable gastric band (LAGB) is a procedure used in bariatric surgery. Despite its decrease in popularity due to its high reoperation rate and suboptimal clinical response, managing the complications of LAGBs remains an important component of general and bariatric surgeons' work. Only two case studies describe return to theatre to excise scarring, which has continued to cause symptoms after LAGB removal.

: Metabolic and bariatric surgery (MBS) is a well-established treatment for severe obesity, yet its effects in patients with inflammatory bowel disease (IBD) are not well understood. MBS in this population presents unique challenges, including the potential for exacerbating inflammatory disease activity and causing complications such as malnutrition and medication malabsorption. This study aims to assess the long-term outcomes of MBS in IBD patients, focusing on both metabolic outcomes and its impact on the course of IBD.

Background: To determine if the positive outcomes from clinical trials regarding the safety and efficacy of metabolic bariatric surgery are reproducible at a national level.
Methods: A longitudinal registry-based observation study with data collected from all persons undergoing metabolic bariatric surgery in Australia from 28 February 2012-31 December 2021 including data from 122,567 index patients who underwent 134,625 completed bariatric procedures.
Main Outcomes And Measures: Defined adverse outcomes at 90-days (unplanned readmission, intensive care admission and re-operation; death), annual change in weight (percent total body weight loss (TBWL)), diabetes treatment and need for re-operation.

Background: Previous studies showed a high conversion rate and failure of restrictive procedures, including sleeve gastrectomy (SG), adjustable gastric banding (AGB), gastric plication (GP), and vertical banded gastroplasty (VBG) in a long-term follow-up. The current study aims to evaluate the efficacy and safety of a revisional one anastomosis gastric bypass (OAGB) for weight loss and treatment of obesity-related problems after primary metabolic and bariatric restrictive procedures.
Methods: A retrospective study on prospectively collected data was conducted on a sample of 151 patients who experienced insufficient weight loss or weight regain after primary restrictive surgeries and underwent OAGB as a revisional procedure.

Laparoscopic adjustable gastric banding (LAGB) is a type of bariatric surgery. Gastric stenosis or obstruction is a known complication of LAGB; however, its occurrence after band removal is extremely rare. A 60-year-old female, who had undergone LAGB 6 years earlier and band removal 4 years prior, presented to the hospital with recurrent vomiting.
