Laparoscopic sleeve gastrectomy is a well-known method for weight reduction. Post-operative weight loss is a major risk factor for gallstone formation.

To determine whether prophylactic concomitant laparoscopic cholecystectomy should be performed on all patients at the time of laparoscopic sleeve gastrostomy or not.
Patients and Methods:

A retrospective and prospective study on 540 patients with morbid obesity who underwent laparoscopic sleeve gastrectomy; their BMI range was between 38 and 53, their age range was 18 to 63 years, and 335 of them were females. The exclusion criteria were patients with a history of cholecystectomy, gallstone patients or gallbladder polyps more than 1 cm in preoperative abdominal ultrasound, and those who failed to follow-up. All patients were followed up with every 6–12 months, including those who had cholecystectomy by other surgeons.

During the study period, from the total 540 patients who had laparoscopic sleeve gastrectomy, 167 patients (30.92%) had cholecystectomy, out of which 20 patients (3.7%) had achieved 45% weight reduction during the first six months; while in another 6 months, 147 patients (27.22%) had cholecystectomy, achieving additional 30% weight reduction.
Conclusions: The incidence of gallstones after laparoscopic sleeve gastrostomy is about 30.92%, indicating that 69.08% will not have gallstones in the postoperative follow-up period, so it would be unwise to do prophylactic concomitant cholecystectomy for all patients.
