Picture of Appendicitis
Appendicitis is an inflamed appendix. The appendix is a small pouch-like projection at the bottom of the first part of the colon. Overgrowth of bacteria in the appendix causes ppendicitis. If the infection persists, rupture of the appendix can occur and an abscess or peritonitis may form. Appendicitis causes pain in the lower right part of the abdomen. Symptoms and history as well as lab tests (white cell count, urinalysis) and imaging (CT scan, abdominal X-ray, ultrasonography, barium enema, or laparoscopy) help establish the diagnosis. Appendicitis is treated by removing the appendix (appendectomy) and with antibiotics.
