{Reference Type}: Case Reports {Title}: Conversion of one anastomosis gastric bypass to distal Roux-en-Y gastric bypass due to recurrent weight gain and gastroesophageal reflux disease: A video case report. {Author}: Kermansaravi M;Shahabi Shahmiri S;Yarigholi F;Mehraz A; {Journal}: Asian J Endosc Surg {Volume}: 17 {Issue}: 3 {Year}: 2024 Jul 暂无{DOI}: 10.1111/ases.13314 {Abstract}: One-anastomosis gastric bypass (OAGB) complications include inadequate weight loss, recurrent weight gain (RWG), and gastroesophageal reflux disease (GERD). Conversion to distal Roux-en-Y gastric bypass (D-RYGB) may be an effective conversional approach. A 38-year-old female underwent OAGB with a body mass index (BMI) of 53 kg/m2 and 43% initial total weight loss but had RWG to BMI of 44 kg/m2 over 5 years with refractory GERD symptoms. She underwent D-RYGB conversion, creating a 330 cm biliopancreatic limb, 75 cm Roux limb, and 400 cm total alimentary limb length to decrease the chance of malnutrition. At 2 weeks, GERD symptoms were resolved completely. By 12 months, 42% total weight loss was achieved with normal nutritional parameters. For RWG and refractory GERD after OAGB, conversion to D-RYGB can promote weight loss and GERD symptom control while preventing nutritional deficiencies.
