Accessory sulci and segmentation on the surface of the liver: a clinical pitfall

Abstract

Diaphragmatic surface of liver is usually smooth but sometimes it is well marked by the sulci or indentations. Sometimes these sulci were so deep to be termed as fissures as they divide the lobe of liver into different segments. We report the case of accessory sulci along the Anterosuperior surface of the right lobe associated with Reidel’s lobe along the inferior border of the left lobe of same specimen. In another specimen, the sulci were so deep to be termed as fissures, which divides the caudate and quadrate lobe. Knowledge about the accessory sulci and lobes were necessary as they may appear as incidental finding during the laparoscopic examinations. Hence, it is very much promising to know about these sulci and lobes for hepatobiliary surgeons, anatomists and radiologists.

A study on the morphological variations of the liver and its clinical significance

“…These have to be remembered preoperatively when making a diagnosis, as it will guide the Surgeons when he plans to operate on biliary tract or on Porto Caval anastomosis. 6 Considering the development of Liver, Liver plates appear in the middle of 3 rd week of development as a thickening of caudal part of forgut which grows to form hepatic bud which invaginates septum transversum 7 As quoted by Wahane et al liver in some lower animals (E.g. dogs and pigs) shows lobulated appearance separated by connective tissue and this can be applied to human liver by reversion.…”
