The continuing challenge of perforating appendicitis

Abstract

A series of 335 consecutive patients treated for acute appendicitis is presented. The incidence of perforation in the series was 32.2 per cent. The mortality was 0.3 per cent for the total series and 0.9 per cent for those patients with perforating appendicitis. When perforation occurs, a twofold increase in the hospital stay and a threefold increase in hospital costs result. A complication rate of 47.2 per cent in instances of perforation was significantly greater than that noted in instances of nonperforation. A 40 per cent incidence of perforation was noted during the first decade of life, after which the frequency of perforation declines. Beginning with the fifth decade, a progressive increase in the incidence of perforation was noted. Prior to hospital admission, a significant delay was noted among patients with perforation. In addition, those with perforating appendicitis were far more likely to have been seen previously by a physician who failed to advise hospital admission. Finally, a significant inhospital delay, from admission to operation, was noted in patients with perforating appendicitis. While geographic access to health care did influence the incidence of perforation, insurance status and possession of a telephone did not.
