What does "gastrectomy" refer to?

The term "gastrectomy" specifically refers to the surgical procedure involving the excision of the stomach. It derives from the Greek roots "gastro," which means stomach, and "ectomy," which means removal or excision. This procedure can be performed for various medical reasons, including cancer, ulcers, or severe obesity. The other choices pertain to different organs; for example, the removal of the gallbladder is called cholecystectomy, the excision of the uterus is known as hysterectomy, and the removal of the lung is referred to as pneumonectomy. Understanding these medical terminologies is essential for recognizing the specific procedures related to surgical interventions in different parts of the body.
