儿童胆管扩张症的CT诊断及分型(附97例分析)

CT diagnosis and classification of pediatric cholangiectasis (analysis of 97 cases)

目的 :探讨CT检查对儿童胆管扩张症的诊断价值及分型方法。方法 :回顾性分析了 97例胆管扩张症的CT特征 ,按胆管受累部位分为肝外型、肝内型、肝内外混合型。结果 :97例胆管扩张症表现为肝内、肝外胆管单独或同时不同程度地扩张 ,其中肝外型 6 4例 (6 6 .0 % ) ;肝内型 3例 (3.1% ) ;肝内外混合型 30例 (30 .9% )。结论 :CT能清楚地显示扩张胆管的部位及其与周围结构的关系并且无创伤 ,因此CT是儿童胆管扩张症的重要检查方法。

Objective:To study the diagnostic value and classified methods of pediatric cholangiectasis with CT examination.Methods:CT features of pediatric cholangiectasis with 97 cases were analyzed retrospectively from 1995 to 1999.It was classified into intrahepatic,extrahepatic and mixed type according to the pathological localizations of biliary duct.Results:In 97 cases,there were 64 cases(66%)with extrahepatic type,3(3.1%)with intrahepatic type and 30(30.9%)with mixed type.Conclusion:CT is an important diagnostic method in pediatric cholangiectasis,because firstly,CT can accurately show the pathological positions of cholangiectasis and the relationship between biliary duct and the organs around it,and secondly,CT is also a non-traumatic examination.
