Abstract
Laparoscopic sleeve gastrectomy (SG) is the most common bariatric surgical procedure worldwide. Approximately 20%-30% of patients present with weight loss failure or reflux following SG, which might require reoperative surgery. We present the surgical outcomes and complications following reoperative bariatric surgery at a tertiary care centre. Prospectively collected data of all patients undergoing reoperative bariatric surgery from 2008 to 2021 were analysed retrospectively. Weight loss, resolution of comorbidities and complications following reoperative surgery were evaluated. Twenty-six patients were included in the study. The mean age was 38.8 (10.8) years. The primary procedure performed was laparoscopic SG in all cases. Nine patients underwent Roux en Y gastric bypass (RYGB) (one banded RYGB) and 14 underwent one anastomosis gastric bypass (OAGB) (three-banded OAGB). Three patients underwent resleeve. The most common indication was weight loss failure (65.3%). Fifteen patients were diagnosed to have hiatal hernia intraoperatively and concomitant repair was performed. The mean body mass index before revision surgery was 42.7 (9.8). It was 32.6 (5.7) kg/m2 and 33.0 (6.1) kg/m2 at 1 and 3 years, respectively. Age and pre-revision surgery excess weight correlated with weight loss (r = -0.79 and r = 0.99, respectively). Leak and bleeding occurred in one and two patients, respectively. There were two band-related complications and one 30-day mortality. Re-operative bariatric surgery following SG has adequate weight loss with acceptable complication rates. Band placement in re-operative surgery might lead to a higher complication rate.
