A giant choledochal cyst in a 17 year old female managed in a resource limited setting: A case report

Introduction and importance: Choledochal cysts are rare congenital bile duct anomalies that lead to cystic dilatations of the biliary tree. This condition is very rare in Africa. When these cysts exceed 10 cm in diameter, they are referred to as giant choledochal cysts, which are much rarer. Giant choledochal cysts present both a diagnostic and surgical challenge. We present a case of a giant Choledochal cyst surgically managed in a resource limited setting with excellent outcome.

Case presentation: A 17-year-old female presented with 4 months history of progressive abdominal distension associated with abdominal pain, yellow discoloration of eyes, and occasional constipation. Abdominal CT-scan revealed a huge cystic mass in the right upper quadrant extending inferiorly to the right lumbar region. Complete excision of a type IA choledochal cyst was done plus cholecystectomy in addition to bilioenteric reconstruction. The patient recovered uneventfully.

Discussion and conclusion: To the best of our knowledge, this is the largest giant Choledochal cyst reported in literature. Even in a resource limited settings, sonography and a CT scan may be all that is required to make a diagnosis. During surgical excision, the surgeon should take extra caution to carefully dissect the adhesions off the giant cyst for a successful complete excision.
