During laparoscopic cholecystectomy, the critical view of safety (CVS) is achieved when which two structures, and only those two structures, are seen entering the gallbladder?
- A Cystic duct and cystic artery ✓
- B Common hepatic duct and cystic artery
- C Cystic duct and common bile duct
- D Right hepatic duct and cystic duct
Correct answer: A. Cystic duct and cystic artery
Explanation
The Critical View of Safety (CVS), as defined by Strasberg, requires: (1) the hepatocystic triangle to be cleared of fat and fibrous tissue, (2) the lower third of the gallbladder separated from the liver bed, and (3) only two structures (the cystic duct and cystic artery) visualised entering the gallbladder. Achieving CVS before clipping is the primary technique for preventing common bile duct injuries during laparoscopic cholecystectomy. Misidentification of the CBD as cystic duct is the most common error.
