A surgeon performing a laparoscopic cholecystectomy must carefully identify the hepatocystic triangle (Calot's triangle) to avoid injury to bile duct structures. Which are the three boundaries of this triangle?

• A Common hepatic duct, common bile duct, and inferior surface of the liver
• B Cystic artery, common hepatic duct, and cystic duct
• C Cystic duct, common hepatic duct, and inferior surface of the liver ✓
• D Cystic duct, gallbladder neck, and hepatic artery proper

Explanation

Calot's triangle (hepatocystic triangle) is bounded superiorly by the inferior surface of the right lobe of the liver, medially by the common hepatic duct, and laterally/inferiorly by the cystic duct. The cystic artery and right hepatic artery typically run within this triangle. Correct identification of these boundaries before clipping is critical to avoid accidental ligation of the right hepatic artery or common hepatic duct.
