Summary
This trial compares two methods for removing large bile duct stones in patients where standard methods fail. One method uses a camera and laser/electric shock to break up the stones, while the other uses a balloon to widen the duct opening. The goal is to see which method is more effective, safer, quicker, and less costly.
Who is the study for?
This trial is for adults over 18 with gallstone disease, specifically those with large bile duct stones (>1cm) confirmed by imaging tests. It's not for pregnant individuals, prisoners, those unable to consent, under-18s, or patients with biliary cancer or past stomach or biliary surgeries.
What is being tested?
The study compares two methods of removing large bile duct stones: one starts with papillary balloon dilation and the other begins with intraductal lithotripsy using cholangioscopy guidance. The focus is on effectiveness, safety, time needed and costs.
What are the potential side effects?
Potential side effects may include discomfort at the procedure site, bleeding, infection risk from the interventions and possible complications related to endoscopic procedures such as pancreatitis.

Active Control
Group I: Intraductal lithotripsyActive Control1 Intervention
Cholangioscopy enables therapeutic intervention including intracorporeal electro-hydraulic and laser lithotripsy for biliary stone disease with favorable efficacy and safety.
Group II: Papillary Balloon dilationActive Control1 Intervention
Balloon dilation of the Ampulla of Vater after a small sphincterotomy is an alternative technique that allows for removal of large bile duct stones in a safe and effective manner.

Other Research
Cholangioscopy guided intraductal lithotripsy is a treatment for gallstone disease that involves the direct visualization and fragmentation of bile duct stones using laser or electrohydraulic energy. This method allows for precise targeting and breaking down of stones, which can then be more easily removed or passed naturally.
The direct visualization aspect ensures that the procedure is accurate and minimizes damage to surrounding tissues. This is particularly important for patients as it reduces the risk of complications, shortens recovery time, and improves overall outcomes compared to more invasive surgical options.
Other common treatments for gallstone disease include endoscopic retrograde cholangiopancreatography (ERCP) with stone extraction and oral bile acid dissolution therapy, which work by either mechanically removing the stones or chemically dissolving them, respectively.
