# Biliary Cyst: An Unusual Cause of Cholestasis Post Cholecystectomy

## TL;DR

A 40-year-old woman developed a biliary cyst after gallbladder removal, leading to jaundice, which was successfully treated with surgery.

## Contribution

This case highlights biliary cysts as an unusual cause of cholestasis after cholecystectomy.

## Key findings

- The patient presented with obstructive jaundice due to a class I biliary cyst.
- Endoscopic stenting resolved symptoms, followed by successful surgical resection.
- Early surgical intervention reduced cancer risk and improved outcomes.

## Abstract

Biliary cysts are relatively uncommon and they can be congenital or acquired and can have various presentations such as cholelithiasis, cholangitis, jaundice, and pancreatitis. Biliary cysts are associated with a high risk of biliary cancers and such risk increases with age. Identification of biliary cysts warrants an aggressive approach to lower cancer risk. Surgical management has a high success rate and it lowers morbidity, mortality, and cancer risk. We present a 40-year-old female who had a cholecystectomy in 2016. She presented with obstructive jaundice and was found to have a class I biliary cyst. She underwent endoscopic retrograde cholangiopancreatography with stenting which led to complete resolution of her symptoms. Later, she underwent elective Roux-en-Y hepaticojejunostomy with cyst resection three months later. She underwent a successful recovery.
