Ultrasound-guided tube meeting vs. small cut for bile duct access
Part of Digestive system clinical trials.
This trial compares two ways to get a tube into your bile duct when the usual method is difficult: one uses a special ultrasound-guided technique to meet the tube from a different angle, and the other uses a small cut to open the duct. It may help your doctor choose the safest and most effective approach for you.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You must be 18 years or older.
- You are having an ERCP, a test that puts a thin tube down your throat to reach the bile duct (the tube that carries bile from your liver).
- It must be your first time having a tube put into your bile duct (your papilla is 'native', meaning untouched).
- The doctor must have had trouble getting the tube into your bile duct — for example, after 10 tries, 10 minutes of trying, or accidentally going into the pancreas tube twice.

This trial tests a newer, ultrasound-guided procedure to drain blocked bile flow using a special metal stent. It may help people who have bile duct blockage but could not have their bile drained successfully with standard ERCP.
This study compares two methods for placing a guidewire into the bile duct when the first attempt fails during an ERCP procedure. If you have a bile duct blockage and your first cannulation was hard, this trial may help find a better technique for you.
This trial studies a new way to access the bile ducts using a scope guided by ultrasound when standard ERCP can’t be done or doesn’t work. It may help people with non-cancer (benign) bile duct blockages get the bile flowing again.
This study tests two ways of opening a blocked bile duct when standard methods fail: one using a special balloon and the other using heat. It looks at which is safer and works better for people who cannot get the usual ERCP or PTCD drainage.
This trial looks at whether a specific small procedure during ERCP helps doctors reach and drain the bile duct when gallstones or bile duct narrowing are suspected. It may help people avoid getting stuck during the procedure and improve how successfully the bile duct can be reached.
This trial looks at whether doing an endoscopic ultrasound (EUS) in the same session as an ERCP (a procedure to open blocked bile or pancreatic ducts) is helpful. It is for adults who need an ERCP for the first time and have not had a pancreatic or bile duct EUS in the last 3 months.
