目的：探讨先天性胆管囊肿的病因、分型、诊断和治疗方法。方法：回顾１９８６至１９９６年１０年间收治的先天性胆管囊肿２８例进行分析。结果：２８例中Ⅰ型１９例（６７８５％），ＩＶＡ型８例（２８６％），ＩＶＢ型１例（３６％）。Ｂ超检查２６例，２４例手术证实；ＣＴ９例７例手术证实。手术治疗为最佳手段，以囊肿切除为首选。本组２５例手术治疗，囊肿切除１３例（占５２％）。结论：Ｂ超为主要诊断手段。先天性胆管囊肿癌变率随病程延长而逐渐上升，故切除囊肿为首选治疗手段
Objective: To investigate the etiology, classification, diagnosis and treatment of congenital bile duct cysts. Methods: We reviewed 28 cases of congenital bile duct cysts treated during the 10 years from 1986 to 1996. RESULTS: Of the 28 cases, 19 (67.8%) were type I, 8 (28.6%) were IVA type, and 1 (3.6%) were type IVB. B-ultrasound examination in 26 cases, 24 cases confirmed by surgery; CT9 cases 7 cases confirmed by surgery. Surgical treatment is the best method, and cystectomy is the first choice. In this group of 25 cases of surgical treatment, cystectomy in 13 cases (52%). Conclusion: B-mode ultrasound is the main diagnosis method. The cancer rate of congenital biliary cysts increases gradually as the duration of the disease increases, so removal of the cyst is the preferred treatment
