Summary

Using a needle knife papillotome by an experienced endoscopist, endoscopic sphincterotomies were performed in difficult cannulation cases. In a prospectively collected database, we investigate the complications of those with ampullary impacted stone.

Detailed description

The endoscopic sphincterotomy with needle knife papillotome is a well-established advanced endoscopic technique in difficult cannulation cases. Choledocholithiasis impacted at the ampulla of Vater is occasionally seen. Inflammed surrounding mucosa frequently accompanies. Whether sphincterotomy with a needle knife increases the bleeding complications is to be elucidated in this study.
