Preoperative EUS for bile duct cancer

This study looks at how well a special ultrasound-guided biopsy checks lymph nodes before surgery or liver transplant for bile duct cancer. The goal is to see if this method accurately shows whether the cancer has spread to nearby lymph nodes.

This study looks at the use of endoscopy (a thin, flexible tube with a camera) to diagnose and treat growths in the pancreas, bile ducts, or nearby areas. It aims to understand how well this approach works in people who need it as part of their standard care.

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.

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 a new way to take a sample from a narrowed bile duct using a special ultrasound. It may help doctors diagnose the cause of the narrowing without more invasive procedures.

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.
