Comparison of two methods for difficult bile duct access during ERCP
Part of Digestive system clinical trials.
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.
Summary written for real people, not researchers, by Clin2.
Who can take part
- 18 years old or older
- Need an ERCP to treat a blockage in your bile duct (e.g., from gallstones, narrowing, or tumor)
- Must have a natural opening (no prior sphincterotomy)
- Cannulation was difficult: took more than 5 minutes, tried more than 5 times, or accidentally entered the pancreatic duct
- No tumor at the ampulla (opening of the bile duct)
- No previous stomach surgery that changed the anatomy (like Billroth II or Roux-en-Y), no bleeding problems, and no recent acute pancreatitis

This trial compares two endoscopy approaches to drain a blocked bile duct caused by gallstones. It may help people who can’t safely have standard surgery decide which drainage method works best after an initial ERCP plan fails or is limited.
This study compares two different devices used during a procedure called ERCP to look at and take samples from a narrowed bile duct. The goal is to see which one is better at helping doctors diagnose the cause of the narrowing.
This trial compares two ways of placing plastic stents to relieve bile duct blockage in people with advanced cancer at the liver. The goal is to find which method is better at keeping bile flowing and reducing symptoms.
This trial studies how doctors should best check and manage people with suspected bile duct stones. It may help improve the accuracy and safety of next-step testing and treatment.
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.
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.
