Calot triangle

Pronunciation: kah-LOH

Anatomical landmark in cholecystectomy bounded by the cystic artery, common hepatic duct, and cystic duct.

Full Definition

A critical anatomical region in laparoscopic cholecystectomy bounded by the cystic artery superiorly, the common hepatic duct medially, and the cystic duct laterally. Also known as the hepatocystic triangle, this area contains the cystic artery and must be carefully dissected during cholecystectomy to achieve the critical view of safety. Named after Jean-François Calot, proper identification and dissection of this triangle is essential for safe gallbladder removal and prevention of bile duct injury.

Usage

Usage note: Capitalize as it is an eponym; apostrophe in Calot's is optional but maintain consistency.
