[Evaluation of endoscopic papillary balloon dilation (EPBD) using one-step catheter for removal of common bile duct stones].
We compared the results of EPBD in 18 patients using one-step catheter (one-step group) with those in 46 patients using usual two-step catheter (two-step group). The frequency of endoscopy and bile duct clearance were the equal in both groups. Pancreatitis occurred in only one patient of two-step group. Elevations of the amylase values were the equal in both groups. Amylase values after EPBD tended to decrease in 11 patients whose amylase values were above 500 IU/l before EPBD. Using one-step catheter in EPBD was useful for removing common bile duct stones easily and safety.
