胆道术后并发症的MRI表现分析

目的　明确胆道术后综合征的MRI表现,寻找其真正病因。方法　回顾性分析 41例胆道术后并发症的上腹部MRI检查资料,观察其有无胆管扩张、狭窄、胆管炎、残余结石、残余胆囊等改变。结果　41例胆道术后并发症患者中 38例有胆道异常改变,其中胆管扩张 20例,胆管结石 16例,胆管炎 13例,胆管狭窄 7例,肝门胆管肿瘤 3例。胆管扩张多在术后 3月内出现,胆管炎症和狭窄多在术后半年以后出现。结论　胆道术后并发症主要由胆管扩张、狭窄和残留结石所致,MRI是诊断胆道术后并发症敏感而有效的手段。

Postcholecystectomy Biliary Disorders: Evaluation with MRI

Objective To define the MRI features of biliary postoperative disoders,so as to find its exact causes.Methods MRI informations of 41 patients with biliary postoperative disoders were retrospectively evaluated to find whether there were such disorders as biliary dilatation,stricture,cholangeitis,remnant stones,remnant gallbladder,etc.Results The biliary abnormality was found in thirty-eight of the 41 patients,including ductal dilatation in 20,intraductal stones in 16,cholangietis in 13,ductal stricture in 7,tumors in hepatic hila in 3.The biliary dilatation commonly presented within 3 months after operation while the biliary stricture and cholangeitis presented commonly 6 months after operation.Conclusion The biliary postoperative disoders is mainly caused by biliary dilatation,stricture and remnant stone,MRI is the sensitive and effective method for diagnosis of biliary abnormalities.
