Example

Strasberg type
D - lateral injury to the extrahepatic duct

Result: Strasberg type D: lateral injury to the extrahepatic bile duct (partial, without loss of continuity); a major injury.

The tool opens with these values already filled in. Replace them with your own.

What the result means

Type A / B / C
Minor injuries: leak from a small duct in continuity (A); occlusion of an aberrant sectoral duct (B); leak from an aberrant sectoral duct not in continuity (C).
Type D
Lateral injury to the extrahepatic bile duct (partial, without loss of continuity). A major injury.
Type E
Transection of the main bile duct (E1-E5 by level, the Bismuth analogue). A major injury.
