Cholelithiasis Following Laparoscopic Sleeve Gastrectomy: A Retrospective Cohort Study

Cholelithiasis subsequent to laparoscopic sleeve gastrectomy has been the subject of only few studies. In this study we have evaluated the incidence of this disorder and a number of possible predictive risk factors in laparoscopic sleeve gastrectomy patients.

A retrospective cohort study was carried out on prospective database of patients who had undergone laparoscopic sleeve gastrectomy between January 2016 and December 2018 with a follow-up period of 12 months. Those patients with a previous history of cholelithiasis, cholecystectomy, or weight-reduction surgeries as well as those found to have gallbladder stone, sludge, or polyps on routine preoperative ultrasound and the patients underwent a revision bariatric surgery were excluded from this study.

A total of 70 patients who had undergone laparoscopic sleeve gastrectomy were studied and the incidence of cholelithiasis was shown to be 12.9% during the follow-up period of interest, based on ultrasound findings. None of the potential risk factors studied in this study including age, gender, amount of postoperative weight reduction, physical activity status, nutrition status, and comorbidities (diabetes mellitus, hypothyroidism, hyperlipidemia) was found to have a significant association (P-value of).
