Brief Summary

Although EPBD has a lower risk of post-ERCP bleeding and long-term complications than EST and is easier to perform in altered/difficult anatomy, EPBD is reserved for patients with bleeding diathesis by current consensus because some studies reported a higher risk of pancreatitis. However, recent meta-analyses indicate that short EPBD duration increases the risk of post-ERCP pancreatitis, and EPBD with adequate duration has a similar pancreatitis risk and a lower overall complication rate compared with EST for choledocholithiasis. Therefore, this study aim to compare long-duration EPBD vs EST in the treatment of extrahepatic biliary stones.

Study Arms (2)

long duration EPBD group

EXPERIMENTAL

Balloon dilation was performed using wire-guided hydrostatic balloon catheters. An 8-mm dilatation balloon was used for EPBD. Balloons were gradually inflated to maximum pressure for 3 minute, and complete inflation was verified by fluoroscopy. Stones were removed by standard techniques, including balloon or basket catheters.

Procedure: long duration EPBDProcedure: EST

endoscopic sphincterotomy (EST) group

ACTIVE COMPARATOR

After deep cannulation was achieved, a complete sphincterotomy was performed with a 25-mm pull-type sphincterotome (Clever Cut 3; KD-V411M, Olympus, Tokyo, Japan) and the sphincter was divided up to the transverse duodenal fold. A complete sphincterotomy was defined by the free passage of a fully bowed sphincterotome and the presence of spontaneous bile drainage.
