Conditions

Difficult cannulation of ampulla of Vater during Endoscopic Retrograde Cholangiopancreatography (ERCP) procedure ERCP&#45

Interventions

Precut Needle Knife Sphincterotomy is a procedure for coping with difficult cannulation

this procedure uses needle knife to cut ampulla of Vater to identify opening of bile duct for deep cannulation into the bile duct.,Precut Pancreatic Sphincterotomy is a procedure for dealing with diff

this procedure uses traction type papillotome to cut the septum between pancreatic duct and distal bile duct in ampulla of Vater to gain access for deep cannulation to bile duct.
