胆道良性狭窄金属支架置入术后并发症及其处理

目的探讨金属支架置人治疗胆道良性狭窄的并发症。方法随访5例胆道良性狭窄应用金属支架治疗的病人，由于反复出现寒战发热，合并支架内结石形成，胆管阻塞，其中4例行手术取出支架。结果4例病人手术取出金属支架，术中见金属支架被胆泥堵塞，胆管壁黏膜破坏，支架取出困难；行胆肠吻合胆管内置管引流。2例病人因置人金属支架后反复胆管炎，胆汁性肝硬化，肝功衰竭死亡。结论金属支架不适合应用于良性胆道狭窄。

Complications of metal stent placement for benign biliary tract stricture and their management

Objective To explore the complications of metal stent placement for benign biliary tract stricture. Methods The clinical data of 5 patients with benign biliary tract stricture treated with metal stent placement in our hospital were retrospectively analyzed. Results All the 5 patients developed cholangitis. Of the 5 patients, 2 died because of biliary cirrhosis and liver failure and 3 had to be reoperated on to take out the metal stent. Chol-mud clogging and breakdown of the mucosa of biliary duct were found during the operation. Choledecojejunostomy and T-tube drainage were performed once again. Conclusions Metal stent placement is not appropriate for treatment oI benign biliary tract stricture.
