肝移植术后胆管狭窄的超声表现

目的 了解肝移植术后胆管狭窄的超声表现.方法 采用超声观察41例肝移植术后胆管狭窄患者肝内外胆管有无扩张及其内径、胆管壁厚度及其回声,并与46例肝移植术后无胆管并发症者比较.结果 胆管狭窄组的肝内胆管内径、胆管壁厚度、肝内胆管扩张和胆管壁回声增强的发生率均大于无胆管并发症组,差异具有统计学意义(P＜0.05).结论 肝移植术后出现肝内胆管扩张、胆管壁增厚及回声增强、胆管腔变细等征象,对于胆管狭窄的诊断有重要价值.

Ultrasonographic characteristics of biliary stricture after orthotopic liver transplantation

Objective To evaluate the charateristics of biliary stricture after orthotopic liver transplantation(OLT) by ultrasound. Methods Diametes,thickness,characteristic echo of bile were observed by ultrasound in 41 patients with biliary stricture after OLT,and the results were compared with those of 46 patients without biliary complication after OLT.Results The diameter of intrahepatic bile,thickness of bile,incidence of intrahepatic bile dilation or hyperechogenicity in biliary stricture patiens were higher than those in patients without biliary complication,there were significant differences between two groups(P＜0.05).Conclusions The series of ultrasonographic character such as bile dilation,thickeness or hyperechogenicity of biliary wall,thin of bile duct are available to diagnose biliary stricture.
