Summary

This study looks at whether an improved endoscopic ultrasound (EUS) can better find cancer in lymph nodes of people with bile duct cancer. About 250 patients with presumed resectable cancer will get the enhanced EUS before surgery. The goal is to see how many patients are spared unnecessary surgery because the test finds cancer spread that would make surgery ineffective.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

What this could lead to: If successful, this could improve how doctors decide if surgery is worthwhile for bile duct cancer patients, potentially avoiding unnecessary operations.
What could go wrong: This is an observational study, not a treatment trial. It may not change outcomes directly, and the improved technique might not be better than current methods.
