During a laparoscopic cholecystectomy, the surgeon dissects Calot's triangle to safely identify the cystic structures. Which structure forms the medial boundary of Calot's triangle?
- A Cystic duct
- B Inferior surface of the liver
- C Common hepatic duct ✓
- D Right hepatic artery
Correct answer: C. Common hepatic duct
Explanation
Calot's triangle is an anatomical space dissected during cholecystectomy to identify the cystic artery and duct. Its boundaries are the common hepatic duct medially, the cystic duct inferiorly, and the inferior surface of the liver superiorly. The cystic artery typically runs within this triangle. A common mistake is confusing the cystic duct as the medial boundary, but it actually forms the inferior boundary.
