segmentectomy
Surgical removal of a specific anatomical segment of an organ, typically liver or lung.
Full Definition
Segmentectomy refers to the precise surgical removal of one or more anatomically defined segments of an organ while preserving the remaining functional tissue. In hepatic surgery, this involves removal of liver segments based on Couinaud classification, while in thoracic surgery, it involves removal of bronchopulmonary segments. This technique allows for oncological resection while maximizing preservation of organ function, particularly important in patients with limited hepatic or pulmonary reserve.
Usage
Usage note: Specify the anatomical segments involved for precision.
