全覆膜金属支架治疗良性胆道狭窄的初步研究

目的探讨全覆膜胆道金属支架治疗良性胆道狭窄的安全性及其疗效。方法36例良性胆道狭窄患者行全覆膜胆道金属支架置入术治疗，术后每1～2个月接受1次门诊随访，观察并发症发生及胆道狭窄改变情况。结果36例均一次性成功置入全覆膜胆道金属支架，未出现与操作相关的严重并发症，支架放置3～6个月后全部成功拔除，其中28例（77．8％）良性胆道狭窄消失。结论置入全覆膜胆道金属支架治疗良性胆道狭窄是安全的，近期疗效显著。

Temporary placement of fully covered metal stent for benign biliary strictures

Objective To explore the efficacy and safety of temporary placement of fully covered metal stent in the treatment of benign biliary strictures.Methods Fully covered metal stents were placed in 36 patients with benign biliary strictures.All patients were followed up every 1-2 months and the stents were removed when adequate biliary drainage was achieved.Results Resolution of the benign biliary strictures was achieved in 28 of 36 patients (77.8％ ).All fully covered metal stents were removed successfully.Complications were observed in 3 patients (8.3％) after stent placement and in 1 (2.8％ ) after stent removal.Conclusion Temporary placement of fully covered metal stents for benign biliary strictures is safe and efficacious.Further investigation is required to longer follow-up.
