One-Anastomosis Gastric Bypass Revision for Gastroesophageal Reflux Disease: Long Versus Short Biliopancreatic Limb Roux-en-Y Gastric Bypass.

Purpose: One-anastomosis gastric bypass (OAGB) may be associated with refractory gastroesophageal reflux disease (GERD). The nature of this GERD remains unclear. This complication can be treated either with an additional enteroenterostomy without shortening of gastric pouch (long biliopancreatic limb Roux-en-Y gastric bypass (L-BPL-RYGB)) or revision to conventional short biliopancreatic limb Roux-en-Y gastric bypass (S-BPL-RYGB).

Management of acute intra-abdominal sepsis caused by leakage after one anastomosis gastric bypass.

Background: Leakage after one-anastomosis gastric bypass (OAGB) is fortunately rare (<1%), but it remains the most severe complication. Few published data exist on this specific issue.

Objectives: To analyze the results from patients who presented with acute intra-abdominal sepsis (AIAS) caused by leakage after OAGB.

Preoperative oral polymeric diet enriched with transforming growth factor-beta 2 (Modulen) could decrease postoperative morbidity after surgery for complicated ileocolonic Crohn's disease.

Objective: Exclusive polymeric diet enriched with transforming growth factor-beta 2 (ANS-TGF-β2) has been used for remission induction and maintenance in pediatric Crohn's disease (CD). Its use in the preoperative setting has never been evaluated. The aim of this study was to evaluate preoperative ANS-TGF-β2 to decrease postoperative complications after surgery for complicated ileocolonic CD.

One thousand single anastomosis (omega loop) gastric bypasses to treat morbid obesity in a 7-year period: outcomes show few complications and good efficacy.

Background: A short-term randomized controlled trial shows that the one anastomosis gastric bypass (OAGB) is a safe and effective alternative to the Roux-en-Y gastric bypass (RYGB).

Objective: The aim of this study is to evaluate the OAGB at our University Hospital between 2006 and 2013.

Patients: One thousand patients have undergone an OAGB.
