MCQ – 100779

Correct Answer � D Explanation

Calot’s triangle, or the hepatocystic triangle, is an important anatomical region encountered during cholecystectomy. It is used to identify structures such as the cystic artery before ligation.

Boundaries of Calot’s Triangle (modern definition):

• Medial boundary: Common hepatic duct

• Inferior boundary: Cystic duct

• Superior boundary: Inferior surface of the liver (or right lobe of liver)

Contents of the triangle:

• Most commonly, the cystic artery traverses within this triangle but is not a boundary itself.

Reason to rule out other options:
A. Common hepatic duct – Forms the medial boundary of the triangle.
B. Cystic duct – Forms the inferior boundary.
C. Right lobe of liver – Forms the superior boundary.
