Ursodeoxycholic Acid for 6 Months After Bariatric Surgery Is Impacting Gallstone Associated Morbidity in Patients with Preoperative Asymptomatic Gallstones.

UDCA for 6 months after bariatric surgery seems to reduce the incidence of gallstone-associated morbidity when compared to the current literature. Thus, our results call the concept of prophylactic concomitant cholecystectomy in patients with asymptomatic gallstones into question while at the same time paving the way for a future clinical trial.
