IBC Oxford Oral Abstract 49 - Naturally banded laparoscopic sleeve gastrectomy: two years follow up, from a randomised controlled trial

Background Laparoscopic sleeve gastrectomy (LSG) is the most common bariatric procedure. Banded sleeve is reported to improve the long-term result of LSG on weight loss but, as a foreign body, it has many serious complications. Objective The aim is to test the efficacy of using a natural band with LSG. Methods This study is a prospective randomized controlled trial, including 80 patients with morbid obesity. The study was conducted in Minia university hospital between November 2022 and January 2025. Patients were randomly assigned to 2 equal groups, Group 1: operated by LSG plus banding using the round ligament of the liver or a tight omental flap. In Group 2: patients were operated on by LSG without banding. All patients completed at least two years follow up. Results The mean follow-up period was 25.5 months. At 2 years, the mean gastric volume was significantly less in banded group (142.3 ml) than in the non-banded group (218.7 ml) (P <0.000), the mean %EWL was significantly higher in banded group (87%) than in the non-banded group (81.8) (P = 0.000). The mean %TWL was significantly higher in banded group (41%) than in the non-banded group (38%) (P = 0.034). The mean score of food tolerance was 21.5 in banded Group versus 22.9 in in non-banded Group (P = .000). Conclusion After 2 years follow up, naturally banded LSG leads to better weight loss than non-banded LSG with minimal sleeve pouch dilatation.
