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

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.
