[Risk assessment of the acute pancreatitis development after papilla Fateri balloon dilatation].

Data of 241 patients with acute cholecystitis, complicated with obstructive jaundice are analyzed. The risk of the acute pancreatitis development after choledocholithotomy, endoscopic papillosphincterotomy (EPST) and balloon dilatation of the papilla Fateri is assessed. Thus, choledocholithotomy and EPST, combined with the simultaneous manipulations on the terminal part of the common bile duct, are more often followed by the acute pancreatitis. Whereas the balloon dilatation of the papilla Fateri is more often followed by an asymptomatic hyperamylasuria. Demonstrated, that difficulties by papilla Fateri cannulation during EPST furthers the pancreatonecrosis development. The authors suggested a marked balloon catheter, which allows safely and effectively dilate papilla duodeni. The optimal diameter of the balloon is showed to be 1 sm wide.
