摘　　要：对15例先天性胆管扩张症进行光镜、电镜及组织化学观察,发现胆总管壁病变严重,且扩张段与狭窄段的病变存在一定差异,结合胆汁淀粉酶水平(平均值3 048.08U),提示狭窄段的存在系先天发育异常与异常胰胆管合流共同作用的结果。Fifteen cases of type-I congenital choledochal cyst (CCC)were treated in our department from 1990 to 1993,Mean abe of patients was 7 years,All the patients underwent excision of the cyst and reconstruction of the bile duct,Light and electron microscopic and histochemi- cal studies of the dilated and the constricted portions of the excised cysts were made,The pathological chanses were obvious.The level of amylase in bile increased in all ca- ses,at mean value of 3048.08u.It is thought that the formation of the stricture portion of CCC is resulted from the conjunct effect of the congenital dysplasia and abnor- mal panereatobiliary junction.
