This retrospective cohort study of 162 patients with morbid obesity examined weight loss outcomes at multiple intervals during the first year after bariatric surgery. Sex and type of surgery were not significantly associated with weight loss at any interval. Among 140 patients without prior cholecystectomy, 8 (5.7%) required postoperative cholecystectomy.

ABSTRACT

The significant outcome of bariatric surgery (BS) is weight loss, which may be affected by many factors, such as initial body weight before surgery, sex, and dietary intake. Moreover, rapid weight loss is associated with an increased incidence of postsurgical cholelithiasis. To investigate the observed weight loss outcomes during the first year after BS, we investigated the factors that may influence weight loss and to detect the efficacy of prophylactic ursodeoxycholic acid against gallstone formation. This was a retrospective cohort study of all patients with morbid obesity who underwent BS in the hospital and completed a 1-year follow up. Patients with a previous BS or a history of cholecystectomy before BS were excluded. Data were extracted from the medical records at multiple postoperative intervals. There was significant weight loss in terms of percentage of excess weight loss and reduction in body mass index postoperative. A significant correlation was found between the percent of excess weight loss and age, initial body mass index, and initial weight, but there was no significant correlation with sex or type of surgery. The incidence of postoperative cholecystectomy is almost negligible. A significant association was found between age and weight loss after BS. ursodeoxycholic acid is an effective prophylaxis to decrease the incidence of cholecystectomy after BS.
