title: Anatomic liver resection of right paramedian sector: ventral and dorsal resection.
abstract: The purpose of anatomic resection of the liver is to systemically eliminate malignant tumors that spread via the portal vein. Moreover, it results in reducing bleeding and bile leakage from the cut surface of the liver because Glisson's pedicle resection leads to parenchyma transection. Anatomical resection includes hemi-hepatectomy, sectionectomy, and segmentectomy. Recently, it has been noticed that this concept is not always appropriate for the liver resection including the right paramedian sector. It can be divided vertically into the ventral and the dorsal area according to the ramification of the third order of the portal veins. In the present study, we focused on the right paramedian sector and described techniques of surgical procedures of hepatectomy including resection of the ventral or dorsal areas.
