6. CONSEQUENCES OF BILE DUCT INJURY
Devastating complication of cholecystectomy—
Both for patient and operating surgeon
Patient
Morbidity (40-50%)
• Physical
Bile leak associated
Biliary stricture associated
• Mental and social
Health quality of life (SF26) worse in 3-7 out of 8 domain when compared to patient who
underwent noncomplicated lap chole (de Reuver PR, Endoscopy. 2008)
Patient usually resume 3 months late to non complicated lap chole counterpart.
• Economical
Hospital cost (direct and indirect)
Loss of work
Use of disability benefit
Mortality
• 2-4 %
Schreuder A.M, et, al. Digestive surgery, 2020.
The life-time hazard ratio of death, either immediately or
later, due to a BDI sustained during cholecystectomy is
2.8 (as compared to patients who had an uneventful
cholecystectomy with no BDI
Flum DR, JAMA.
2003
7. CONSEQUENCES OF BILE DUCT INJURY
Patient
Economical Morbidity
• “Financial disaster” as the costs of management of a BDI are 5–26
times the costs of a cholecystectomy.
• The mean cost of management of common bile duct transection/excision
increased to US$ 9061 from the mean cost of US$ 2681 for an uncomplicated
cholecystectomy.
• The median total cost of the management of BDI was INR 93,046 (range 22,204-
562,790). 15–20 times the cost of an uncomplicated cholecystectomy
• Indirect cost including the loss of wages, attendant cost and much other are not
included

Litigation
• For Lay people BDI is always health error or negligence on surgeons' part
• Litigation claim incidence
4-6 per 10,000 cholecystectomies in UK.
About 0.08% of laparoscopic cholecystectomies in Netherland.
81 (78%) out of 104 litigations following laparoscopic cholecystectomy were related to
BDI, vascular injury (7%), bowel injury (2%), and other injuries (13%)

Compensation
• Most of the cases goes in favor of patients
• Surgeon or associated health institute usually land off with huge compensation
• Compensation in the UK ranged from £ 40,000 to 100,000
• Compensation in the USA ranged from US$ 214,000 - US$ 508,341

Sir Anthony Eden
• Underwent open cholecystectomy on 12th April 1953.
• Reexplored on 29th April.
• He was then flown to the USA where repair of a bile duct
injury was performed by Richard Cattell of the Lahey Clinic
on 10th June.
• He underwent a total of as many as 4 operations including
a liver resection
• He died on 5th March 1970.

• Both intrahepatic and extrahepatic biliary system are
totally depended upon arterial supply.
• About 50 % of hepatic arterial supply is for biliary

Two thirds of arterial input came from ascending vessels
and only one third from descending vessels.

Type I: Open type was defined as a cleft in which the right hepatic
pedicle was visualized and the sulcus was opened throughout its length.
Type II: if the sulcus was open only at its lateral end.
Type III If the sulcus was open only at its medial end.
Type IV: Fused type was defined as one in which the pedicle was not
visualized.
