Choledochal Cyst: A Retrospective Study Case Series

Background and Objectives Choledochal cyst is an uncommon congenital malformation of biliary system, involving cystic dilatation of intrahepatic and/or extra hepatic bile duct. The estimated incidence is one in 1000 live birth in Asian population [1-2] with female to male ratio is 31. The objective of this study is to study the presentation, diagnosis, treatment and outcomes of choledochal cyst in our tertiary care center. Materials and Methods A retrospective review of patients, from Jan 2012 to April 2017, who were diagnosed as Choledochal cyst and treated by surgical intervention and their outcomes, in our tertiary care center. Results We analyzed 16 cases of choledochal cyst. The condition commonly affected the pediatric age group (0 to 10 years) with female preponderance. Most common presenting symptom was pain in abdomen (75 %) and jaundice (53 %). However the classical triad of abdominal pain, jaundice, and an abdominal mass was not seen in any of the cases. Ultrasonography was diagnostic in all cases. Todani type I cyst was the most common type. Eleven out of 16 cases underwent complete cyst excision with cholecystectomy and Roux-en-Y hepaticojejunostomy without any major complication, however so many cases were not operated due to, not fit for surgery, not willing for surgery etc. Conclusion Choledochal cyst is a clinical condition occurs, commonly in younger age group that is conveniently diagnosed on ultrasound and has a rewarding outcome if operated.
