肝内记忆金属支架介入术治疗肝门部胆管癌的应用研究

目的：探讨经皮经肝置入记忆金属内支架术，在治疗肝门部胆管癌的作用。方法：20例估计不能手术切除的肝门部胆管癌患者，置入记忆金属内支架（PMSE）20例，观察其减黄效果、并发症发生率、再梗阻时间及生存率。结果：全组术后2-3月的减黄有效率92.85%；引流效果与Bismuth分型有密切关系。引流维持通畅平均时间7.3个月。术后随访平均存活期7.3个月。结论：对无切除可能的肝门部胆管癌，经皮经肝记忆金属内支架置入术可作为首选的安全有效的姑息性治疗手段。

The application study on biliary stents endoprosthesis in the treatment of hilarbiliary carcinoma

Objective:To evaluate the position of biliary stents endoprosthesis in the management of hilarbiliary carcinoma. Methods:20 cases with inoperable patients of malignant hiarbiliary carcinoma were investigated.they were used by PNSE.The indication of curative effect,the rate of complication,the time of reobstruction and the survival rate were observed. Results:The total effective rate were 92.85%.It is found that the outcome were closely related to the Bismuth types.the median time of reobstruction took place within 7.3 months in PNSE.in the longterm follow-up,the median survival were 7.3 months of PMSE. Conclusion:Percutaneous biliary stents endopresthes is a safe and useful managment for the malignant hilarbilary carcinoma and should be for palliating jaundice in the inoperable patients.
