colectomy

This term is a specialized medical descriptor used primarily in clinical settings, surgical reports, and patient records. It carries a neutral, technical tone and is rarely used in casual conversation unless a patient is describing their own medical history.

Because it describes a specific surgical procedure, it is often modified by adjectives such as total, partial, or right/left to specify the extent of the resection. It should not be confused with a colostomy, which refers to the creation of an artificial opening (stoma) rather than the removal of the organ itself.
