Abstract: Objective To observe the effect，postoperative complications and treatment costs of different bile duct stent selection on malignant common bile duct obstruction and investigate the optimal treatment. Methods Forty- seven consecutive patients with malignant bile duct obstruction underwent endoscopic biliary stenting by ERCP surgery in the Hepatobiliary Surgery of our hospital from July 2010 to December 2015. Of all patients，16 were treated by metal stent（group A），17 had single plastic stent（group B）and 14 had multiple plastic stent（group C）. The patency duration，complications and operation cost were recorded and compared between three groups. Results For the patients with pancreatic cancer，the mean stenting patency durations of group A and group C were significantly longer than of group B，but there was no significant difference between group A and group C. For cholangiocarcinoma and periampullary carcinoma patients，the mean stenting patency durations of group A and group C were significantly longer than of group B，and group C was slightly better than the group A but the difference was not statistically significant. Conclusion As regard to the patients with malignant common bile duct obstruction，endoscopic biliary stenting should follow the individualized treatment option program for the purpose of improving treatment effect，reducing complications and costs.
