Effect of Endoscopic Papillary Balloon Dilation on ERCP Complications

Summary

The purpose of this study is to determine how different endoscopic papillary balloon dilatation (EPBD) duration time affects the complications after endoscopic retrograde cholangiopancreatography (ERCP) in the treatment of common bile duct stones.

PROCEDURE

30" group

A small sphincterotomy (EST) was performed prior to the EPBD, the length of a small sphincterotomy was considered as no larger than the range which from the orifice to the top one-third of the papilla. a CRE balloon (diameter 8, 9, 10, 11, 12, 13.5, 15; Boston Scientific) was chosen according to the diameter of bile duct. It was placed across the papilla orifice and then gradually filled with diluted contrast in 15 seconds. When the waist disappeared, the balloon was inflated till 30 seconds prior deflated. The stones were then retrieved by a basket or retrieval balloon. Mechanical lithotripsy was used if necessary.

PROCEDURE

60" group

A small sphincterotomy (EST) was performed prior to the EPBD, the length of a small sphincterotomy was considered as no larger than the range which from the orifice to the top one-third of the papilla. a CRE balloon (diameter 8, 9, 10, 11, 12, 13.5, 15; Boston Scientific) was chosen according to the diameter of bile duct. It was placed across the papilla orifice and then gradually filled with diluted contrast in 15 seconds. When the waist disappeared, the balloon was inflated till 60 seconds prior deflated. The stones were then retrieved by a basket or retrieval balloon. Mechanical lithotripsy was used if necessary.

PROCEDURE

180" group

A small sphincterotomy (EST) was performed prior to the EPBD, the length of a small sphincterotomy was considered as no larger than the range which from the orifice to the top one-third of the papilla. a CRE balloon (diameter 8, 9, 10, 11, 12, 13.5, 15; Boston Scientific) was chosen according to the diameter of bile duct. It was placed across the papilla orifice and then gradually filled with diluted contrast in 15 seconds. When the waist disappeared, the balloon was inflated till 180 seconds prior deflated. The stones were then retrieved by a basket or retrieval balloon. Mechanical lithotripsy was used if necessary.

PROCEDURE

300" group

A small sphincterotomy (EST) was performed prior to the EPBD, the length of a small sphincterotomy was considered as no larger than the range which from the orifice to the top one-third of the papilla. a CRE balloon (diameter 8, 9, 10, 11, 12, 13.5, 15; Boston Scientific) was chosen according to the diameter of bile duct. It was placed across the papilla orifice and then gradually filled with diluted contrast in 15 seconds. When the waist disappeared, the balloon was inflated till 300 seconds prior deflated. The stones were then retrieved by a basket or retrieval balloon. Mechanical lithotripsy was used if necessary.
