Definition: The term 'Appendectomy' refers to removing the appendix (the small intestine that runs down between your right hip bone and your stomach) from a person's abdomen, typically at a hospital or surgery center. Definition: A surgical procedure where part of the abdominal wall is removed or cut off by a medical technician or surgeon. The end result is usually a hole in the abdominal wall, which allows access to the organs that were removed. In addition, it involves removing parts of the body's digestive system, such as bile glands and gallbladder. It's important to note this is not an appendectomy; instead, it's called an Appendectomy (also spelled "Appendectomy" or "appendicectomy") because it refers to the removal of part of the appendix.
