Digital scope imaging for non-yellowing bile duct narrowing

This trial uses a bile sample to help diagnose the cause of a bile duct stricture (a narrowing) that was not clearly identified by standard tests. It may help patients avoid more invasive procedures.

This trial looks at whether DNA fragments in bile can help doctors tell if a bile duct stricture is cancerous or not. It may provide a less invasive way to get a clear diagnosis.

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 study looks at a new way to detect bile duct cancer (cholangiocarcinoma) using samples taken during a routine ERCP. It tests a special protein marker that might help doctors diagnose the condition more accurately.

This study tests an artificial-intelligence computer add-on (an AI “camera guide”) used during a procedure that looks inside the bile ducts. If you have a bile duct narrowing, it may help the doctor more quickly and accurately identify the cause while you undergo the usual procedure.

This trial tests an endoscopic (camera-based) approach to treat bile duct narrowing that happens after a liver transplant. It may help improve bile flow and liver blood test results when the narrowing is in the bile duct area near where the liver’s bile ducts split.
