# Pancreaticoduodenectomy for type I choledochal cyst in an elderly patient: a case report

## TL;DR

A 77-year-old patient with a rare bile duct malformation underwent surgery, highlighting the need for more research on adult cases.

## Contribution

This case report adds to the limited understanding of choledochal cysts in elderly patients.

## Key findings

- A 77-year-old patient was diagnosed with a type IA choledochal cyst.
- Pancreaticoduodenectomy was performed due to pancreatic head involvement.
- The case highlights a significant research gap in adult choledochal malformations.

## Abstract

Choledochal cyst is a rare malformation of the bile ducts with high risk of malignancy. For type I cysts surgery is the mainstay of treatment. Biliary cysts are considered congenital and mostly diagnosed in children; however, the prevalence and management in adult population is poorly defined. A 77-year-old patient who presented with severe right upper quadrant pain was diagnosed with type IA choledochal cyst. Due to pancreatic head involvement in the lesion, pancreaticoduodenectomy was performed. This case emphasizes a great research gap in the understanding of choledochal malformations, especially in adults.
