{Reference Type}: Case Reports {Title}: A Rare Case of a Giant Choledochal Cyst in a Caribbean Infant. {Author}: Ali PV;Ali F;Sudama S;Roop L; {Journal}: Cureus {Volume}: 16 {Issue}: 4 {Year}: 2024 Apr 暂无{DOI}: 10.7759/cureus.57735 {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.
