Total Cyst Excision of Type I Choledochal Cyst 2 Years After Roux-enY Hepatocholangiojejunostomy: Report of a Case

Background: Choledochal cysts are rare congenital or acquired cystic dilation of the intra- or extrahepatic bile ducts. It is well known that choledochal cyst is a precancerous lesion and cancer usually occurs at the site of bile stasis, irritation, and inflammation. Case presentation: We present a rare case of cyst excision of type I choledochal cysts after Roux-en-Y Hepatocholangiojejunostomy about two years ago. A 17-years-old girl visited our hospital complaining of transient epigastric pain. History study revealed that she had undergone Roux-en-Y Hepatocholangiojejunostomy for cholecochal cyst (type I) without cyst excision 2 years ago in local hospital because of severe adhesion of the cyst to the portal vein and pancreas. In our department?the patient underwent total cyst excision and postoperative pathological study revealed fibrous wall tissue, confirming the diagnosis of choledochal cyst. The patient has no recurrence to date and has recovered well. Conclusion: This case shows that proper surgical management is necessary for patients with congenital choledochal cyst.
