Background
Laparoscopic one-anastomosis gastric bypass (LOAGB) is an effective, relatively low-risk procedure and can be reversed.
Patients and methods
Between June 2014 and September 2018, 310 morbidly obese patients have undergone LOAGB surgery.
Results
The mean operating room time was 69 min. Median postoperative length of stay was 2.1 days. The;Deg;BM;Deg;I has decreased from 49.3±9.9 to 38.8±9.7 kg/m, 33.7±4.7 and 28.8 kg/m at 6, 12, and 24 months postoperatively, respectively. The percentage of excess weight loss is, respectively, 50±26, 62±25, and 72±18% at 6, 12, and 24 months postoperatively.. Major complications have occurred in a total of 11 (3.5%) patients. One patient has suffered from postoperative gastrojejunal anastomotic leakage. Five patients have suffered from massive postoperative bleeding. Two patients have intractable bile reflux after minigastric bypass. Omega loop gastric bypass was converted to Roux-en-Y gastric bypass in these two patients. One anastomotic stenosis needed dilatation over three sessions. One patient developed port site hernia 6 months postoperatively. This patient was explored and managed laparoscopically. One patient presented 15 months after minigastric bypass with perforated gastrojejunal anastomotic ulcer that was treated by omental patch repair. There were no postoperative mortalities.
Conclusion
LOAGB can be regarded as a simple, safe, effective, and reversible bariatric procedure.
