What does "gastrectomy" refer to?

Gastrectomy refers specifically to the surgical removal of part or all of the stomach. The term itself is derived from "gastro," which means stomach, and "ectomy," which indicates surgical removal. This procedure may be performed to treat various medical conditions, such as stomach cancer, severe obesity, or chronic ulcer disease. Understanding the components of medical terminology helps clarify meanings: "gastro" identifies the organ involved, and "ectomy" conveys the action taken, which is removal.

The other options relate to different surgical procedures—repair versus removal and the indication of different organs, which makes them distinct from gastrectomy. This precision in language is essential in the medical field for clear communication and accurate treatment plans.
