ABSTRACT
Type Ⅰ congenital biliary dilatation is a congenital biliary duct defect disease.It is also called congenital choledochocele cyst (CCC).Endoscopic ultrasonography (EUS),magnetic resonance cholangiopacreatography (MRCP) and endoscopic retrograde cholangiopancreatography (ERCP) are very important for the diagnosis.Operation is generally regaded as the best choose.It is recommended that cholecystectomy + choledochal cyst excision + hepatic duct jejunum Roux-Y anastomosis is the chief therapeutic method.This article reviews the pathogenesis,classifications,diagnosis and treatment of the disease.
ABSTRACT
Objective To summarize the etiology,classification and clinical characteristics of congenital bile duct dilatation and our experience in its diagnosis and troatment.Methods The clinical data of 37 cases of congenital bile duct dilatation were retrospectively analyzed.Results The 37 cases included TypeⅠin 31 cases,Type Ⅱ in 1 case,Type Ⅳ in 4 cases,and Type Ⅴ in 1case.All of the patients underwent operative treatment.External drainage of was done in 2 cases,Roux-en-y cystojejunostomy in 3 cases,exeisison of cyst cyst and Roux-en-y hepaticojejunostomy in 31 cases and left hepatectomy in 1case with malignant change of cyst.Five cases had postoperative complications that recovered with non-operative treatment.Thirty-two cases were cured.There were no operative deaths.Conclusions Congenital bile duct dilatation should be treated as soon as possible.Excision of the cyst and Roux-en-y hepaticojejunostomy can reduce long-term postoperative complications and is the rational treatment for congenital bile duct dilatation.
