Komi classification of bile duct cysts
Komi classification of bile duct cysts, as stated by Komi et al, divides anomalous union of the pancreatico-bile ducts (AUPBD) into 3 types based on the angle of union of the ducts 1.
type I: union of the ducts at a right angle to each other
- type Ia: without dilatation or
- type Ib: with dilatation of the common channel.
type II: union of the ducts with an acute angle between them
- type IIa: without dilatation (IIA) or
- type IIb: with dilatation of the common channel
type III: comprises of complex patterns of accessory pancreatic ducts, with or without intricate duct networks
- type IIIa: is similar to the classic pancreas divisum with biliary dilatation
- type IIIb: characterized by the absence of the Wirsung’s duct
- type IIIc1: tiny communication exists between the main duct and the accessory ducts
- type IIIc2: comprises of a common channel made up of common and accessory ducts of equal caliber
- type IIIc3: total or partial dilatation of the ductal system
