Routine versus selective bile-duct imaging during gallbladder removal

ChOlanGiography Performed Routinely Versus Selectively During Cholecystectomy: A NAtional Registry-based Randomized Controlled Trial

Not applicable Interventional Karolinska Institutet · NCT07002619

This trial will test whether routinely taking X-ray images of the bile ducts during gallbladder removal or only doing them when needed leads to fewer complications for adults having gallbladder surgery without suspected bile duct stones.

What this trial studies

This is a national, multicenter randomized registry-based trial in Sweden embedded in the GallRiks registry that randomizes adults undergoing cholecystectomy without preoperative suspicion of common bile duct stones to routine intraoperative cholangiography (IOC) or selective IOC. In the routine arm surgeons perform IOC for all procedures while in the selective arm IOC is performed only when preoperative tests or intraoperative findings suggest stones or unclear anatomy. GallRiks will supply baseline, operative and follow-up data and predefined outcomes include postoperative pancreatitis, cholangitis, bile duct injury, need for ERCP, and overall morbidity and mortality. The registry-based design enables broad real-world enrollment across Swedish hospitals and capture of rare but important adverse events.

Who should consider this trial

Good fit: Adults (18 years or older) undergoing cholecystectomy at participating Swedish hospitals who have no preoperative suspicion of common bile duct stones and who are not pregnant or suspected to have biliary malignancy.

Not a fit: Patients with preoperative evidence of common bile duct stones, children, pregnant patients, or patients with suspected gallbladder or bile duct cancer are excluded and unlikely to benefit from the trial findings.

Why it matters

Potential benefit: If successful, the results could either reduce unnecessary bile-duct procedures and their complications or help avoid missed stones and their harms, improving safety of gallbladder surgery.

How similar studies have performed: Observational and registry studies have shown mixed results on routine versus selective IOC and high-quality randomized evidence is limited, so this pragmatic RCT addresses an important knowledge gap.
