超声诊断先天性胆管囊肿及其癌变的价值

目的 探讨超声诊断先天性胆管囊肿及其癌变的临床价值。方法 先天性胆管囊肿22例，男10例，女12例。超声检查观察囊肿的部位、大小、形态、合并炎症、结石与癌变等情况，并与手术病理检查结果进行对比研究。结果 超声检查诊断为先天性胆管囊肿22例，其中肝外型胆管囊肿54．5％(12／22)、混合型胆管囊肿45．5％(10／22)。其中单纯囊肿22．7％(5／22)，囊肿合并炎症77．3％(17／22)，合并结石54．5％(12／22)，癌变22．7％(5／22)。与手术病理对照，结果 除1例超声诊断为先天性胆总管囊肿而手术证实为肝总管囊肿，其部位略有差异外，其余全部符合。结论 超声检查不仅是诊断先天性胆管囊肿的可靠方法，而且对明确囊肿有无合并炎症、结石，特别是癌变，有重要的临床实用价值。

Value of Ultrasonography in Diagnosis of Congenital Bile Duct Cyst and of Its Cancerization

Objective To probe the clinical value of ultrasonography in diagnosis of congenital bile duct cyst (CBC) and of its cancerization. Methods Twenty two cases of CBC,including 10 males and 12 females,undertook ultrasonic examinations.The location,size,shape of the cyst and their complications such as inflammation,calculus and cancerization were observed. The ultrasonic results were compared with those of the operation and pathology of the patients . Results Twenty two CBC were diagnosed by ultrasound. The rates of extrahepatic bile duct cyst and both intra and extrahepatic bile duct cyst were 54.5% (12/22) and 45.5% (10/22) respectively. The rate of simple cyst was 22.7% (5/22). The rates of complications which were inflammation,stone and cancerization were 77.3% (17/22),54.5%(12/22) and 22.8% (5/22) respectively. The results of ultrasonography agreed with those of operation and pathology except one congenital bile cyst of common hepatic duct which proved in operation was diagnosed as congenital common bile duct cyst by ultrasonography. Conclusion Besides a reliable method in diagnosis of CBC,ultrasonic examination is of important clinical practical value in confirming whether the cyst is complicated with inflammation,calculus and,especially,cancerization.
