Appendectomy is performed urgently usually. Thomeo is Latin for dissect or cut. Lapar - is abdomen (belly) in medical Latin. Laparotomy is opening of belly. Appendectomy is cutting of appendix. Laparoscopy is looking (by scope) into belly. Antibiotics almost always are given prior to surgery as soon as appendicitis is suspected. Few patients have mild "confined appendicitis" localized to a

At this point diagnosis is usually clear. In cases if it is not, there is Laparoscopy. Laparoscopy is a surgical procedure. Small fiberoptic tube with a camera is inserted into the abdomen through a small puncture in abdominal wall. Yet there is no test that will diagnose appendicitis with 100% certainty. The position of the appendix may vary. If it is longer than normal, appendix may go
