Description
Kotaro Takeshita and co-authors describe a rescue method for hard cases of bile duct access during an endoscopic procedure, published in 2026. When wire-guided methods fail, doctors need another way in. A common fallback cuts with a needle knife, but loose mucosa can hide the duct opening after the cut.
Their method first cuts away, cold and without electric current, the protruding tissue at the duct mouth. Only then is the needle-knife cut made. They report the case of a frail older woman with jaundice from pancreatic cancer, where both standard methods had failed. Folds, a diverticulum, and redundant mucosa made the cut hard. The case sets out each step, with images, as a guide for similar rescues.
