Methods: Needle-shaped knife was used for endoscop- ic sphincterotomy (EST) in 476 patients with biliary or pancreatic diseases from March 1995 to October 2000. Results: Direct incision was made in 243 patients, papillary fenestration in 89, and opposite incision in 144. The papilla located beside and in the diverticu- lum in 56 and 12 patients, respectively. EST emer- gency was made in 147 patients. ERCP after EST be- cause of the difficulty in intubation was made suc- cessfully in 62 patients. Mild complications occurred in 14 patients (2.94%), all of whom were cured af- ter symptomatic treatment. Conclusions: EST with needle-shaped knife has such advantages as safety in operation and convenience in incision. It is suitable for the papilla with different shape, with a higher success rate.展开更多
