Background and Objectives: Choledochal cyst is an uncommon congenital malformation of biliarysystem, involving cystic dilatation of intrahepatic and/or extra hepaticbile duct. The estimated incidence is one in 1000 live birth in Asian population [1-2] with female to male ratio is 3:1. 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 ofpatients, 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. Elevenout 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.
