What does appendectomy refer to?

The term "appendectomy" specifically refers to the surgical removal of the vermiform appendix, which is a small, tube-like structure connected to the large intestine. This procedure is most commonly performed when a patient has appendicitis, an inflammation of the appendix that can lead to serious complications if not treated promptly.

The term is derived from "appendix," indicating the specific organ involved, and "ectomy," which means surgical removal. This clear etymological breakdown reinforces the definition, making it easy to remember the association with the organ in question. In contrast, the other options refer to unrelated medical procedures or conditions, such as the removal of the gallbladder, treatment for heart issues, or fluid accumulation in the body.
