Is this trial a fit for you?

Likely a good fit

Adults 18 and older scheduled for bariatric surgery who have not had gallbladder, biliary, or liver surgery and can consent.

Probably not a fit

Patients who already have gallstones or biliary disease detected before surgery or who cannot take Ursochol may not benefit.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

After bariatric surgery, gallstone problems can rise, and many patients need gallbladder removal later. This trial uses ultrasound-based assessment to detect gallstones or biliary issues before surgery to guide preventive treatment with ursodeoxycholic acid. The goal is to see if targeted prevention reduces later gallbladder complications and reoperations. The study focuses on adults planning bariatric surgery and excludes those with prior gallbladder or liver procedures. It is conducted at Esbjerg Hospital in Denmark.

Why it matters

Potential benefit: If successful, patients may have fewer gallbladder problems after bariatric surgery and fewer repeat surgeries.

How similar studies have gone: Past data suggest ultrasound and preventive treatment can reduce post-surgical gallstone risk, but this specific preoperative imaging approach in bariatric patients is being evaluated.
