Right Hemihepatectomy

초록

The right hemihepatectomy is a standardized procedure. It entails resection of liver parenchyma on the right side of the Cantlie line towards the right of the middle hepatic vein. According to the new classification proposed by the International Hepato-Pancreato-Biliary Association in 2000, the right hepatectomy entails resection of segments V, VI, VII, and VIII. The right hepatectomy is mostly indicated for primary liver or biliary malignancies involving metastatic tumors, particularly metastatic colorectal cancer. Less frequently, this operation is indicated for large, symptomatic benign tumors or for large retroperitoneal tumors involving the right liver. Rarely, liver or biliary infections or bile duct injuries are an indication for the right hepatectomy. Tumors involving the main inflow pedicle and/or outflow venous drainage to the right liver typically require right hepatectomy for removal. Similarly, this procedure is required for diffuse tumors involving most of the parenchyma or all segments of the right liver. The right hepatectomy is a major liver resection that requires preoperative liver function, resectability, and assessment of future liver remnant (FLR) volume. © Springer Nature Singapore Pte Ltd. 2023.
