摘要
目的:根据胆道扩张的程度及形态判断胆道梗阻的性质。方法:通过对CT图像上仅仅表现为胆道扩张的76个病例进行分析,观察并记录肝内胆管扩张的程度、形态,肝外胆管扩张末端变化,梗阻部位及胆囊增大、胰管扩张等指标。结果:恶性病变肝内胆管表现为中重度扩张,多数呈软藤状,肝外胆管绝大多数在近段区域突然中断;而良性病变肝内胆管轻度扩张,多数呈枯枝状,肝外胆管在远段区域逐渐变细。结论:根据肝内胆管扩张的程度与形态、肝外胆管扩张末端变化及梗阻部位等,能够对梗阻的性质做出判断。
Objective： To determine obstruction property according to degree and morphology of bile tract dilation. Methods： 76 cases with bile tract dilation were analyzed. Degree and morphology of intra-hepatic bile tract dilatation, change of end of extra-hepatic bile tract dilatation, obstruction, gallbladder expansion and pancreatic duct dilation were observed and registered. Results： The symptoms of malignant intra-hepatic bile tract dilatation were as following： moderate and severe dilation, most of soft ratten-like bile tracts and a sudden cut in proximal coverage; while the symptoms of optimum intra-hepatic bile tract dilatation were as follows ： slight dilation, most of withered bile tracts and a gradual thinning in distal coverage. Conclusion： obstruction property can be determined by degree and morphology of intra-hepatic bile tract dilation, change of end of extra-hepatic bile tract dilation, and obstruction location.
