Summary

Limited endoscopic sphincterotomy with balloon dilation（ESBD）is a promising technique in treating common bile duct stones. It had the similar success rate of stone extraction, but its incidence of complications remained uncertain. However, there is no clinical evidence and guideline to define the optimal duration of balloon dilation so far. So we designed a prospective randomized trial to compare the effect of three different duration of balloon dilation during ESBD so that we can find the optimal duration of the balloon dilation.

Conditions

  • Common Bile Duct Stones

Interventions

PROCEDURE

30" group

A limited sphincterotomy (EST) was performed prior to the EPBD.The length of the sphincterotomy incision was limited to a third of the size of the papilla. A CRE balloon (diameter 10, 12, 15, 18) was chosen according to the diameter of bile duct. The balloon was then gradually filled with diluted contrast medium under endoscopic and fluoroscopic guidance to observe the disappearance of the waist. Once the waist disappeared, the balloon remained inflated for 30 seconds. The stones were then retrieved by a basket or retrieval balloon. An ENBD catheter (.) was routinely placed into the CBD after stone removal.

PROCEDURE

60" group

A limited sphincterotomy (EST) was performed prior to the EPBD.The length of the sphincterotomy incision was limited to a third of the size of the papilla. A CRE balloon (diameter 10, 12, 15, 18) was chosen according to the diameter of bile duct. The balloon was then gradually filled with diluted contrast medium under endoscopic and fluoroscopic guidance to observe the disappearance of the waist. Once the waist disappeared, the balloon remained inflated for 60 seconds. The stones were then retrieved by a basket or retrieval balloon. An ENBD catheter (.) was routinely placed into the CBD after stone removal.

PROCEDURE

180" group

A limited sphincterotomy (EST) was performed prior to the EPBD.The length of the sphincterotomy incision was limited to a third of the size of the papilla. A CRE balloon (diameter 10, 12, 15, 18 ) was chosen according to the diameter of bile duct. The balloon was then gradually filled with diluted contrast medium under endoscopic and fluoroscopic guidance to observe the disappearance of the waist. Once the waist disappeared, the balloon remained inflated for 180 seconds. The stones were then retrieved by a basket or retrieval balloon. An ENBD catheter (.) was routinely placed into the CBD after stone removal.
