Cystohepatic triangle

Cystohepatic triangle (also known as Calot's triangle) is an anatomical space in the human body. It is a significant area in the field of surgery, particularly in cholecystectomy procedures. The triangle is named after the French surgeon, Jean-François Calot, who first described it in 1891.

Etymology

The term "cystohepatic triangle" is derived from the Greek words "kystis" meaning bladder, and "hepar" meaning liver. The term "Calot's triangle" is named after Jean-François Calot, a French surgeon who first described this anatomical space in 1891.

Anatomy

The cystohepatic triangle is an anatomical space bounded by the cystic duct, the common hepatic duct, and the inferior surface of the liver. It is located in the upper right quadrant of the abdomen, near the gallbladder.

Clinical significance

The cystohepatic triangle is of significant clinical importance in gallbladder surgery, particularly during a cholecystectomy, which is the surgical removal of the gallbladder. The triangle is often explored during this procedure to identify and protect the structures within it, including the cystic artery and the cystic duct.
