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.

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.
