The hidden endoscopic burden of sleeve gastrectomy and its comparison with Roux-en-Y gastric bypass

Background This study aimed to assess the endoscopic burden of bariatric surgical procedures at our trust. This is an enhanced parallel study to “The Hidden Endoscopic burden of Roux-en-Y Gastric Bypass” published in Frontline Gastroenterology in 2013 incorporating the data for sleeve gastrectomy and comparison with Roux-en-Y gastric bypass (RYGB). Methods This is a retrospective study that included 211 patients undergoing sleeve gastrectomy over a 34-month period. We utilized previously collected data for the RYGB patient cohort which included 553 patients over a 29-month period. We searched our hospital endoscopic database for patients who underwent post-operative endoscopy for indications related to their surgery. Results 16.6% of the sleeve gastrectomy patients required post-operative endoscopy, of whom 11.4% underwent therapeutic procedures. This compares to 20.4% of the RYGB cohort of whom 50.4% needed therapeutic procedures (P
