# A Rare Case of a Giant Choledochal Cyst in a Caribbean Infant

## TL;DR

This paper reports the first documented case of a giant choledochal cyst in a Caribbean infant, successfully treated with surgery.

## Contribution

The novelty lies in documenting the first case of a giant choledochal cyst in the Caribbean pediatric population.

## Key findings

- A Caribbean infant presented with a giant choledochal cyst exceeding 10cm in diameter.
- Surgical intervention included cholecystectomy, cyst drainage, and hepaticojejunosotomy.
- Three years post-surgery, the patient showed normal growth and liver function.

## Abstract

Choledochal cysts are uncommon dilatations of the biliary tree. Giant choledochal cysts are those that exceed a maximum diameter of 10cm. Our case describes a female infant who presented to our paediatric surgery department with a three-day history of vomiting, abdominal distention, pale stool, and irritability. On palpation, she was found to have a large abdominal mass and the computed tomography (CT) scan showed a giant choledochal cyst. The patient underwent laparotomy with cholecystectomy, choledochal cyst drainage and complete excision, with hepaticojejunosotomy. At the last follow-up three years post-surgery, all growth parameters and liver enzymes were within normal ranges. To the best of our knowledge, this is the first documented case of a giant choledochal cyst in the paediatric Caribbean population.
