Choledochal Cyst in Children, presentation and outcome - 10 years’ experience from a tertiary care center in Pakistan

OBJECTIVES: This study was done to compare the clinical features, laboratory findings and surgical outcomes of pediatric patients with choledochal cysts. METHODS: Retrospective review of the hospital records of all pediatric patients admitted with choledochal cysts from 2011 to 2021 were collected and analyzed. Patients were divided into two groups; infant (less than one year age) and pediatric (1 to 16 years) for statistical comparison of two groups. RESULT: The study included 34 children, 9 (26.5%) were infant (<1 year) and 25 (73.5%) were more than one year old. Mean age at diagnosis was 15 months with age ranging from 14 days to 16 years. Females were 19 (55.9%) and males were 15 (44.1%). Type-I choledochal cyst was the most common (73.5%), presentation followed by Type-IVA (26.5%) in our patients. Patients from infant group presented with jaundice in 7 (77.7%), and clay-colored stool in 3 (33.3%) as the most common clinical features, while abdominal pain (88%), vomiting (72%), fever (32%) and pancreatitis (32%) were the frequent presentations among older age group. Post-surgical complications of excision of choledochal cyst were observed in 4 (11.7%) patients. CONCLUSION: Choledochal cysts have variable presentations depending upon age of the patients. Complete surgical excision of choledochal cyst is the treatment modality of choice and timely surgical management can prevent complications.
