Strasberg and Bismuth classification
A – bile leak from part ATTACHED to biliary tree (cystic duct or duct of Luschka)
B – BLOCK in part of biliary tree
C – bile leak from CUT-OFF duct (not in communication) with the biliary tree
D – DEFECT (<50%) in common hepatic duct
E – ENTIRE circumference (100%) injury to common hepatic duct (sub-classified using Bismuth classification from E1 to E4 with strictures moving proximally towards confluence; E5 is a separate entity)
- E1 – >2 cm distal to hepatic duct confluence
- E2 – <2 cm distal to hepatic duct confluence
- E3 – hilar stricture with intact confluence
- E4 – hilar stricture with involvement of confluence
- E5 – strictures involving right aberrant sectoral duct and common hepatic duct
