WASHINGTON (Reuters Health) - When someone has all the signs of acute appendicitis, waiting to get a CT scan to confirm the diagnosis is not a good idea, researchers report. Compared with a straight-to-surgery approach, the CT strategy is linked to delayed surgery and increased risk of a burst appendix."There has been a somewhat reflexive use of CT since it has become widely available,” Dr. Herbert Chen of the University of Wisconsin at Madison said during a presentation at Digestive Disease Week 2007, which is underway here.
