Which anatomical triangle bounded by the cystic duct, common hepatic duct, and inferior margin of the liver contains the cystic artery and is dissected during cholecystectomy?

Answer and explanation

Correct answer: A. Calot's hepatobiliary triangle

  1. Step 1: Calot's triangle (hepatobiliary triangle) is bounded superiorly by the inferior surface of the liver, medially by the common hepatic duct, and laterally by the cystic duct.
  2. Step 2: Accurate identification of Calot's triangle and the critical view of safety during laparoscopic cholecystectomy is essential to locate the cystic artery and cystic duct without injuring the common bile duct.
Answer
Calot's hepatobiliary triangle.
Why not the others: 'Hesselbach's triangle' is an inguinal region bounded by the inferior epigastric vessels, rectus abdominis, and inguinal ligament, through which direct inguinal hernias protrude; 'Carotid triangle' is in the anterior neck; 'Femoral triangle' is located in the upper anterior thigh.
