Extrahepatic biliary system and the cystichepatic triangle

anatomotopographic study

Abstract

Introduction: The chromatic triangle (calot triangle) is an anatomical space bounded by the common hepatic duct, or cystic duct and a lower border of the liver. An importance of this anatomical landmark is indisputable for the performance of cholecystectomy. Case report: Dissection of the abdominal region of a male cadaver was performed, followed by dissection of the hepatic pedicle to individualize the studied structures. He observed that a hepatic-cystic junction gave a distance of 2.6 cm in relation to the hepatic hilum, as well as a junction of the cystic duct was made to the right of the hepatic duct. Regarding the structures shown in the cysthepatic trigone, if the trigone was occupied by the posterior hepatic vein and by the anterior cystic and hepatic artery previously. Comments: Videolaparoscopic surgery is essential or detailed knowledge of the topographic anatomy of the abdomen, in particular, of extrahepatic biliary tract, as well as its possible anatomical features to avoid complications during the medical procedure.
