Management of Early Postoperative Bleeding After OAGB: A Single-center Experience.
Surgical Laparoscopy, Endoscopy & Percutaneous Techniques 2023 September 30
INTRODUCTION: One anastomosis gastric bypass (OAGB) has gained popularity among bariatric surgeons due to the shorter operative time, fewer sites for anastomotic leaks and internal herniation, shorter learning curve, ease of reversibility and revision with equivalent results to Roux en Y gastric bypass in terms of weight loss and co-morbidity resolution. We present our experience in managing early postoperative bleeding after OAGB.
PATIENTS AND METHODS: Patients who underwent OAGB in Bariatric Surgery Unit, Ain Shams University Hospitals between January 2016 and January 2023 were followed up for 30 days for early postoperative complications. Patients were 210 females (70%) and 90 males, with a mean age of 41.3±7.1 years, and mean preoperative body mass index of 45.2±6.1 kg/m². The incidence of early postoperative bleeding, the sites of the bleeding and management strategy were reported.
RESULTS: Fourteen of 300 patients (4.67%) developed early postoperative bleeding after OAGB. Intraluminal bleeding occurred in 4 patients, 3 of which were controlled by endoscopy and one by laparoscopic suturing. Intra-abdominal bleeding occurred in 10 patients, 7 of which were successfully managed conservatively, and 3 required laparoscopic management. Two cases had both intra-abdominal bleeding and intraluminal bleeding in the distal stomach, confirmed by intraoperative endoscopy, and controlled by laparoscopic suturing.
CONCLUSION: Early postoperative bleeding after OAGB is a rare complication (4.67%). Conservative treatment is more successful in controlling intra-abdominal bleeding. In case of failed conservative treatment, laparoscopy is the method of choice. Most cases of intra-luminal bleeding need early endoscopic intervention.
