EAES classification matrix for bile duct injuries
For each injury, the surgeon fills in the following matrix
1) Date of injury date____/mo____/year____
2) Date of diagnosis date____/mo____/year____
3) single injury (yes/no)
4) multiple injuries (yes/no), fill in one matrix for each injury, as appropriate
5) injury occurred
a. during laparotomy
b. during laparoscopy
6) total number of cholecystectomies performed by the same unit
a. number by laparotomy
b. number by laparoscopy
c. number of conversions

Time of detection
Indicate Ei, Ep or L
E: Early intraoperative
(de visu, bile leak, IOC)
Ep: Early postoperative

NMBD
MBD: main biliary duct; NMBD: non main biliary duct (Luschka or other accessory duct); level 1: ≥ 2 cm from lower border of superior biliary confluent; level 2:
< 2 cm from lower border of superior biliary confluent; level 3: involves the superior biliary confluent but communication right left is preserved; 4: involves
superior biliary confluent but communication right left is interrupted; 5: right or left hepatic duct or 6 right sectorial (aberrant) duct in continuity; C: Complete; P:
partial; * (indicate % of circumference if known), LS Loss of substance; ** indicate length if known); Me: mechanical; ED energy driven; VBI: vasculobiliary
involvement; RHA: right hepatic artery; LHA: left hepatic artery; ,CHA: common hepatic artery; PV: portal vein; MA: marginal vessels; Ei: Early intraoperative;
Ep Early postoperative (7 days or less); L: late (8 days or more), OC: intraoperative cholangiograms
For example, a complete division made by an energy-driven (ultrasonic) dissector involving the superior biliary confluence with interruption of communication
between the right and left hepatic ducts, without associated vascular injury, detected (intraoperatively) during the operation by the presence of bile would be
classed: MBD 4 O C VBI Ei, ED
The Connor Garden E6 injury is in fact a type 4 with LS: MBD 4 LS.
