Abstract
Background/Aims
Colonoscopy may be helpful in the diagnosis of appendicitis occasionally. However, it is unclear that isolated inflammation at the appendiceal orifice is always suggestive of acute appendicitis. Methods: Eighteen consecutive patients with colonoscopic findings of the isolated inflammatory lesion in the area of the appendiceal orifice were included. Surgical- pathology-proven appendicitis within 6 months after the colonoscopy were defined as 'true-appendicitis'. Results: Of the 18 patients, 16 patients were followed up for more than 6 months. Seven patients underwent appendectomy within 5-79 days after the colonoscopy. Of these, 4 patients (25%) had true-appendicitis, one periappendiceal abscess without appendicitis, two normal appendices. Nine patients did not take appendectomy. Of these, no definite etiology was defined in 6. Of the rest, one patient revealed Crohn's disease, one Behcet's disease and one cecal involvement of distal ulcerative colitis later. Conclusions: Isolated inflammation at the appendiceal orifice does not always suggest acute appendicitis but diverse etiologies. The diagnosis of appendicitis should not be made only by colonoscopic findings but also by clinical course and other imaging studies. (Intestinal Research 2006;4:39-44)
