wedge resection

This term is a highly specialized medical descriptor used primarily in surgical oncology and thoracic or hepatic surgery. It describes a precise geometric approach to tissue removal, contrasting with a lobectomy, where an entire lobe of an organ is excised. The term carries a neutral, clinical tone and is used to communicate the specific scope of a surgical intervention to other healthcare providers or patients.

Because it refers to a specific medical procedure, it is treated as a countable noun in clinical reports (e.g., "multiple wedge resections were performed"). However, it is frequently used in the singular to describe the general technique or a single event.
