Guild-wire for selective biliary cannulation of proximal biliary obstruction / 中华消化内镜杂志

ABSTRACT

Objective To explore the application value of the guide-wire for selective biliary cannulation of proximal biliary obstruction.Methods A total of 344 patients with proximal biliary obstruction were treated by endosocopic retrograde cholangio-pancreatography.Various guide-wire skills,were applied to pass through the stricture of bile duct,so as to reach the target bile duct,and analyzed for their therapeutic effects.Results Selective biliary cannulation of proximal biliary obstruction was completed in 336 patients,after successful cholangiography for therapeutic operation.The overall success rate was 97.67％.There was no procedure-related complications,such as hemobilia or perforation.Conclusion The guide-wire for selective biliary cannulation of proximal biliary obstruction not only improves the success rate of therapeutic endoscopy but also reduces the procedure time and the incidence of complications.
