The cystic node[1][2] (also known as the cystic lymph node,[3][2] cystic lymph node of Lund,[3] Lund's node, or Mascagni's lymph node[4][5][6] and often erroneously referred to as Calot's node[5][6][7]) is the sentinel lymph node of the gall bladder.[5][6][7] It is located within the cystohepatic triangle (Calot's triangle).[8]
Structure[edit]
The cystic lymph node is situated at the neck of the gallbladder.[2][4] It is invariably situated lateral to the biliary tree.[9]
The node receives lymphatic drainage from the gallbladder, cystic duct, hepatic duct, and the superior portion of the common bile duct.[10] It in turn drains lymph into the hepatic lymph nodes.[2][4]
Clinical significance[edit]
It increases in size in cholecystitis and cholangitis;[citation needed] it becomes enlarged in most cases of acute cholecystitis which serendipously also makes it easier to identify in case of subsequent surgery.[10]
It is an anatomic landmark and may be removed along with the gallbladder in cholecystectomy.[citation needed] The node can be used as a landmark to prevend iatrogenic injury during surgery in the cystohepatic triangle so as to avoid the bile ducts and other structures of the porta hepatis.[10]
Research[edit]
According to one retrospective study, the node could be identified in about 78% of patients undergoing laproscopic cholecystectomy; of those in whom the node could be identified, the node was related to the cystic artery in ~97% of cases.[9]
Etymology[edit]
The node is named after Fred Bates Lund (1865-1950), an American surgeon. It was also named after the Italian anatomist and physician, Paolo Mascagni (1752-1815), who first identified the node around 1787.
