METHOD FOR LAPAROSCOPIC LEFT-SIDED LATERAL LIVER SECTORECTOMY Russian patent published in 2017 - IPC A61B17/00 A61B17/132 

FIELD: medicine.

SUBSTANCE: at laparoscopic left-sided lateral liver sectorectomy, the left hepatic artery, the left branch of the portal vein, is circularly isolated from the donor after liver left lobe mobilization. A line of resection is marked on the diaphragmatic surface of the liver 3-5 mm to the right from the crescent ligament of the liver. 2-4 cm² of the liver parenchyma is separated along the intended line. LLS is rotated. 0.5-1 cm² of the liver parenchyma is separated along the boundary between the lower and middle thirds of the furrow between the caudate lobe of the liver and the LLS. Dissector branches are introduced into the formed hole. On the side of the diaphragmatic liver surface, ends of two ribbons are captured by the dissector and removed from the visceral surface of the liver. Liver parenchyma with a portal plate is suspended on the first ribbon. Liver parenchyma with the left hepatic vein is suspended on the second ribbon. Then, the liver parenchyma is separated along the resection planes by the first and second braid. The portal plate is cut, the left hepatic artery, the left branch of the portal vein, is clipped and crossed, stitched with a hardware suture, and the left hepatic vein is crossed. The transplant is taken from the abdominal cavity.

EFFECT: method allows to simplify the technique of liver parenchyma separation for prevention of biliary and vascular complications.
