Background: Severe obesity is common before and after liver transplantation and has been associated with significant morbidity and mortality. Furthermore, it may cause graft dysfunction through the development of recurrent nonalcoholic steatohepatitis.
Methods: We performed Roux-en-Y gastric bypass in two morbidly obese patients who had undergone liver transplantation and had graft dysfunction secondary to recurrent nonalcoholic steatohepatitis.
Results: Both patients demonstrated dramatic weight loss and had normalization of liver enzymes, lipids, and glucose levels. Repeated liver biopsy showed regression of steatosis.
Conclusions: Roux-en-Y gastric bypass can be successfully performed in liver transplant recipients with morbid obesity and may lead to weight loss, correction of metabolic abnormalities, and regression of hepatic dysfunction secondary to recurrent steatosis.

Background: There is controversy regarding which is the best reconstruction technique after the pancreatoduodenectomy. Currently, there are no studies comparing the three most frequent reconstruction techniques: Whipple + Roux-en-Y gastrojejunostomy (WRYGJ), pyloric-preserving + Billroth II (PPBII), and Whipple + BII (WBII).
Methods: Between 2012 and March 2023, 246 patients underwent pancreaticoduodenectomy with the following type of reconstruction techniques: (1) WRYGJ: 40 patients; (2) PPBII: 118 patients; and (3) WBII: 88 patients.

Esophageal carcinoma cuniculatum is a rare histology and can be difficult to diagnose prior to resection. To date, there have been 28 cases of resected esophageal carcinoma cuniculatum reported. Herein we describe a case found in the stomach of a patient who previously underwent a Roux-en-Y gastric bypass surgery.

Background: Irrespective of baseline diabetes status, preoperative hemoglobin A1c (A1C) influences perioperative care in patients undergoing metabolic and bariatric surgery (MBS). Accordingly, the American Society of Metabolic and Bariatric Surgery (ASMBS) endorses that patients undergoing MBS should receive a preoperative A1C test. We aimed to assess the proportion of MBS patients who received a preoperative A1C test and determine whether baseline diabetes status influences receipt of a test.

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.
Ischemic Jejunitis as a Late Complication of Roux-en-Y Gastric Bypass.
ACG Case Rep J

Department of Gastroenterology, District of Columbia Veteran Affairs Medical Center, Washington, DC.
The rising prevalence of obesity has led to a substantial investment in the advancement of treatment options for the disease and its comorbid conditions including lifestyle, pharmacologic, and procedural interventions. In this study, we describe a patient with a history of Roux-en-Y gastric bypass who was diagnosed with ischemic jejunitis on upper endoscopy because of the development of an internal hernia, a known late complication of bariatric surgery. This case highlights the diagnostic utility of endoscopy in postgastric bypass complications and the need for safer alternatives to surgery that have the potential to achieve significant weight loss such as bariatric endoscopic therapies.
