Bile duct injury during laparoscopic cholecystectomy usually follows misidentification of the common bile duct as the cystic duct. The critical view of safety asks for three things before any structure is clipped or divided: the hepatocystic triangle cleared of fat and fibrous tissue, the lower third of the gallbladder separated from the liver bed, and only two structures — cystic duct and cystic artery — seen entering the gallbladder.
When it cannot be achieved, the safer path is a bail-out: subtotal cholecystectomy, fundus-first dissection or conversion, rather than pressing on.
- Confirm all three elements of the critical view of safety before clipping or dividing any structure.
- Pause and document the view, with a photograph where possible.
- When inflammation prevents a clear view, consider subtotal cholecystectomy rather than further dissection.
- Call a second surgeon early in a difficult gallbladder.
Why it matters
Bile duct injury is the complication of a routine operation that most often changes a patient's life.
