During laparoscopic cholecystectomy, the critical view of safety (CVS) — as described by Strasberg — requires dissection of the hepatocystic triangle to clearly identify two structures entering the gallbladder. These two structures are:
- A Cystic duct and right hepatic artery
- B Cystic duct and cystic artery ✓
- C Common hepatic duct and cystic artery
- D Common bile duct and cystic duct
Correct answer: B. Cystic duct and cystic artery
Explanation
Strasberg's Critical View of Safety requires: (1) complete dissection of the hepatocystic triangle so it contains only fat and connective tissue, (2) the lower one-third of the gallbladder separated from the liver bed, and (3) only TWO structures — the cystic duct and cystic artery — seen entering the gallbladder. This prevents misidentification of the common bile duct as the cystic duct, the most common cause of major bile duct injury during laparoscopic cholecystectomy.
