[Intraoperative calibration of the Vater's papilla using Fogarty's biliary catheter].

The study included 20 patients affected by cholelithiasis and choledocholithiasis. Al patients underwent cholecystectomy; after choledochotomy, choledochal stones were removed using a Fogarty's biliary catheter (no. 5) and, subsequently, the papilla was calibrated by inserting the end balloon of the catheter, which and been filled with 0.3 cc of water, beyond the level of the papilla itself. The catheter was then withdrawn. No T-tubes were left in the common bile duct in any patient, no post-operative complications were observed and all patients were dismissed within seven days.
