title: The diagnostic challenge of postoperative acute appendicitis.
abstract: During the period 1979 to 1989, 0.1% of all cases of acute appendicitis at our institution occurred soon after another operative procedure. The interval between primary operation and appendectomy was 5 to 31 days (mean, 14 days). Signs and symptoms did not differ from those of classical acute appendicitis. Duration of symptoms ranged from 12 hours to 8 days (mean, 2.4 days). Perforation was present in 3 patients, suppurative appendicitis in 1 patient, and acute inflammation in 4 patients. Two of the perforations were associated with abscess formation. Morbidity related to the appendiceal condition included hepatic abscesses, septic shock, and prolonged ileus. There was no mortality. Hospitalization ranged from 6 to 80 days (mean, 12.5 days).
