Abstract

Background: Laparoscopic One-anastomosis gastric bypass (LOAGB) has proved to be safe and effective, with short learning curve and low morbidity rate.

Methods: This was a prospective study done from September 2017 to August 2019. Forty morbidly obese patients (27 female, 13 male) were included and all were subjected to Laparoscopic One-anastomosis gastric bypass. This study discussed the patients’ demographics, operative technique, operative records, post-operative outcomes concerning excess weight loss, comorbidities resolution and morbidity rates. Follow up was done at 1, 3, 6, 12 and 24 months postoperative.

Results: Mean patients’ age was 38.5±9.45 years. Mean patients’ BMI was 53.59±6.25 kg/m2. All procedures were completed laparoscopically. Mean operative time was 94.125±33.20 min (range, 65–230 min). The mean length of hospital stay was 2.025±1.32 day. Mean percentage of excess weight loss achieved was 21.03±3.32%, 38.02±5.15%, 58.095±5.83%, 70.98±7.29%, and 78.64±10.3% at 1, 3, 6, 12 and 24 month respectively. Most of co-morbidites were improved or resolved within the first postoperstive year. There was no perioperative mortality whereas total morbidity occurred in 9 patients (22.5%).

Conclusion: LOAGB is feasible, safe with short hospital stay and accepted morbidity rate. Short term outcomes concerning promotion of weight loss and remission/improvement of obesity associated comorbidities are promising.
