The hepatobiliary triangle (or cystohepatic triangle) is an anatomic space bordered by the common hepatic duct medially, the cystic duct inferiorly and the liver superiorly. The cystic artery normally passes through the triangle; this anatomic feature is important during laparoscopic cholecystectomies .
Additional recommended knowledge
Another name used to refer to this region is Calot's Triangle. It is named for Jean-François Calot. Of note, Calot's original description of the triangle in 1891 included the cystic duct, the common hepatic duct, and the cystic artery (not the inferior border of the liver as is commonly believed).
General surgeons frequently quiz medical students on this term and the name for the lymph node located within the triangle, Calot's node. The latter is frequently enlarged due to inflammation of the gallbladder (e.g. cholecystitis) or the biliary tract (e.g. choledocholithiasis) and is removed along with the gallbladder during surgical treatment (cholecystectomy).
