Bismuth Classification of Bile Duct Injury and Its Association with Increasing 30 Days Mortality after Revision Surgery

Abstract

Background: The incidence rate of bile duct injury has not been changed for many years for both open or laparoscopic technique. Open cholecystectomy has risen from 0.5% to 1.4% when gallbladder removal is performed laparoscopically. Injuries of the bile duct system after laparoscopic cholecystectomy are more complex than that after an open approach, causing significant morbidity and even death. From initial classification published by Bismuth, there have been many classifications of common bile duct injury. We would reported the 30 days mortality rate following reconstruction after bile duct injury according to type of Bismuth classification.
 Case Report: 7 cases of common bile duct injury were reported from 2016 until 2018 following cholecystectomy (both open and laparoscopic), all cases were diagnosed as early complication and without intra operative cholangiography performed. The most common bile duct injury was Bismuth type II and IV (2 patients in each type). Reconstruction has been done by hepatico jejunostomy for type III and IV. Choledoco Duodenostomy bypass was done for type I and II. 2 patients with bismuth type IV have long standing cholangitis and cannot survive during 30 days of follow up. 4 others patients could survive with no intra abdominal complication nor other morbidity.
 Conclusion: Bismuth classification was the simpliest type to described the bile duct injury, Bismuth type IV was associated with the high risk of 30 days mortality rate.
