MTP5.06 Comparable Postoperative Outcomes in Obese and Non-Obese Patients Undergoing Benign Biliary Surgery

Abstract Aim Patients with a high Body Mass Index (BMI≥35) undergoing benign biliary surgery are often perceived to be at greater risk for postoperative complications and prolonged post-operative length of stay. This study aims to compare postoperative complication rates between obese and non-obese patients. Methods A retrospective analysis of all consecutive laparoscopic cholecystectomies performed by two biliary surgeons over two years. Patients were divided into two groups based on their BMI (group-1 BMI≤35.0, group-2 BMI35.0) and the outcomes compared. Results 245 patients were identified, 193 patient in group 1 and 52 were in group 2. Median BMI in group-1 was 29 and 39 in group-2. Table below compares the data in both groups.

Surgeons should be encouraged to operate on obese patients to prevent complications associated with gallstone disease.
