What does the suffix -ectomy signify?

The suffix -ectomy is derived from the Greek word "ektome," meaning "excision" or "to cut out." In medical terminology, this suffix indicates a surgical procedure involving the removal or excision of a specific part or tissue from the body. For example, a "appendectomy" refers to the surgical removal of the appendix. The focus of this suffix is clearly on the action of cutting out, which is essential in various medical contexts, especially in surgeries.

The other options refer to different medical concepts. For instance, inflammation is typically indicated by the suffix -itis. Pain is often denoted by the suffix -algia, and obstruction is usually referred to with terms like occlusion or blockage rather than using a specific suffix. Understanding these distinctions helps clarify the meaning and application of medical terms in practice.
