# Laparoscopic management of cystic duct cyst (Type VI): case report

## TL;DR

A rare case of a biliary cyst was successfully treated using minimally invasive surgery.

## Contribution

This is the first reported case of dual biliary cysts managed entirely with laparoscopic surgery.

## Key findings

- Laparoscopic resection of a Type VI cystic duct cyst and Type I choledochal cyst was performed successfully.
- The procedure was completed without complications, highlighting the safety of minimally invasive techniques.
- Magnetic resonance imaging confirmed the biliary anomaly before surgery.

## Abstract

Cystic duct cyst (CDC) is a rare biliary anomaly that may occur in isolation or in association with other choledochal cysts. While individual variants have been described, reports focusing on dual biliary pathology managed by a minimally invasive approach are limited. Surgical resection is recommended to prevent complications, including malignant transformation. We report the case of a 68-year-old woman with a remote history of cholecystectomy who presented with acute pancreatitis. Magnetic resonance cholangiopancreatography identified a CDC associated with dilatation of the common bile duct. Laparoscopic resection of the cysts and biliodigestive reconstruction were performed without complications. This case highlights the novelty of a dual biliary cystic pathology involving a Type VI CDC and a Type I choledochal cyst managed entirely by a laparoscopic approach, emphasizing the feasibility and safety of minimally invasive surgery in complex biliary anomalies.
