Cystic duct cyst: type VI in Todani's classification

Area of Science:

• Hepatobiliary surgery
• Surgical pathology

Background:

• Biliary cysts are congenital anomalies of the biliary tree.
• Todani's classification categorizes biliary cysts into five types.
• Accurate classification is crucial for appropriate management.

Purpose of the Study:

• To address the classification of cystic duct cysts (CDC) within existing biliary cyst typologies.
• To confirm the categorization of CDC based on established classification systems.

Main Methods:

• Review of existing literature on biliary cyst classification.
• Comparative analysis of cystic duct cyst morphology with Todani's classification criteria.

Main Results:

• Agreement with Junquera E et al. regarding the classification of cystic duct cysts.
• Cystic duct cysts (CDC) are confirmed as Type VI according to Todani's classification.

Conclusions:

• Cystic duct cysts (CDC) represent a distinct entity within biliary cyst classification.
• Formalizing CDC as Type VI in Todani's classification aids in standardized reporting and treatment strategies.
