Revisional One Anastomosis Gastric Bypass (OAGB) for Poor Response of Duodenal-Jejunal Bypass with Sleeve Gastrectomy (DJB-SG) (video Report).

Background Bariatric surgery has actually focused not only on obesity but also more on the improvements or remission of the metabolic diseases. Therefore, revisional surgery is indicated for patients with poor response to the primary bariatric surgery to control weight and obesity-associated medical conditions. Method In this video report, the patient was a 27-year-old Asian female with an initial BMI of 36.5 kg/m 2 and poorly controlled type 2 diabetes (HbA1c: 11.9%). She underwent primary bariatric surgery of laparoscopic duodenal-jejunal bypass with sleeve gastrectomy (DJB-SG) in June 2019. She had a nadir BMI of 28.8 kg/m 2 (corresponding body weight of 72 kg) in June 2020. However, she regained weight (BMI: 34 kg/m 2 ) and had a relapse of diabetes with an HbA1c of 12.0% at the time of consultation for revisional bariatric surgery (RBS) in September 2022. After a multidisciplinary team evaluation, laparoscopic procedures of one anastomosis gastric bypass (OAGB) with resizing the gastric tube, removal of duodenal-jejunal anastomosis, and lengthening of the biliopancreatic limb were performed. Results The operative time was 186 min and blood loss was 50 ml. There were no intraoperative or postoperative complications. The patient had an uneventful postoperative course and was discharged on postoperative day 5. At the 3-month follow-up after RBS, the patient had lost 13 kg (weight dropped from 85 to 72 kg) and achieve remission of diabetes with HbA1c of 5.7%. Conclusion Laparoscopic OAGB is technically feasible and practical as a revisional procedure for poor response of DJB-SG.
