hepatectomy
Pronunciation: hep-uh-TEK-tuh-mee
Surgical removal of part or all of the liver, commonly performed for liver tumors or metastases.
Full Definition
Hepatectomy encompasses a range of surgical procedures involving the resection of liver tissue, from wedge resections of small tumors to major anatomical resections removing entire liver segments or lobes. In surgical oncology, hepatectomy is frequently performed for primary liver cancers (hepatocellular carcinoma, cholangiocarcinoma) and colorectal liver metastases. The procedure requires careful preoperative planning including assessment of future liver remnant volume and function. Types include minor resections (wedge, segmentectomy) and major resections (removal of three or more liver segments), with the latter carrying higher perioperative risks but potentially offering better oncological outcomes.
Usage
Usage note: Specify anatomical extent (e.g., right hepatectomy, left hepatectomy, segmentectomy) for clarity.
