Strategies to Minimize Bile Duct Injuries During Cholecystectomies

Primary Prevention Strategies

The World Society of Emergency Surgery emphasizes that technical and procedural considerations must be adapted based on anatomical factors, patient clinical status, disease factors, and surgeon experience, with the Critical View of Safety (CVS) technique being the cornerstone of bile duct injury prevention, carrying a strong recommendation despite low-quality evidence (GRADE 1C) 1, 2
The CVS technique requires achieving all three components before dividing any structures: clear visualization of Calot's triangle, identification of two and only two structures entering the gallbladder, and hepatocystic triangle cleared of all tissue, with a strong recommendation for its use (GRADE 1C) 1, 2, 3

If the CVS is not achievable during a difficult laparoscopic cholecystectomy, perform a subtotal cholecystectomy (STC) as a bailout procedure, with a strong recommendation and moderate quality evidence (GRADE 1B) 1, 2

Intraoperative Cholangiography (IOC) should be used selectively, not routinely, when there is intraoperative suspicion of bile duct injury, misunderstanding of biliary anatomy, or inability to achieve CVS, with a weak recommendation and high quality evidence (GRADE 2A) 1, 2
Indocyanine Green Cholangiography (ICG-C) is a promising noninvasive tool for real-time biliary tract visualization, but routine use to reduce bile duct injury rates is not yet recommended, with a weak recommendation and low quality evidence (GRADE 2C) 1, 2, 5

Early recognition of bile duct injury is the single most important factor for favorable outcomes, with patients having delayed detection having significantly worse 1-year mortality (3.9% vs. 1.1%), and a strong recommendation for early recognition and management 4, 3
For major injuries (Strasberg E), place a drain in the right upper quadrant and transfer the patient to a hepato-pancreato-biliary (HPB) center if insufficient local HPB expertise exists, with a strong recommendation for this approach 4, 3

In patients with acute cholecystitis, perform cholecystectomy within 48 hours and no more than 10 days from symptom onset, with a strong recommendation and good quality evidence (GRADE 1A) 1, 2

In patients with at-risk conditions such as scleroatrophic cholecystitis or Mirizzi syndrome, perform exhaustive preoperative workup to discuss and balance the risks/benefits ratio, with a weak recommendation and low quality evidence (GRADE 2C) 1, 2

Never force dissection when CVS cannot be achieved, as this is when most injuries occur, with a strong recommendation against forced dissection 1, 2
Do not rely solely on adjunctive imaging (IOC, ICG-C) as a substitute for proper surgical technique, as these tools complement but do not replace CVS, with a weak recommendation against over-reliance on imaging 4, 1, 3, 5
