Delayed appendectomy for appendicitis: Causes and consequences

This study was undertaken to describe the causes and consequences of delayed diagnosis and intervention in cases of appendicitis. The hospital records of adult patients undergoing appendectomy during a 4-year period (November 1989 to November 1993) were reviewed, with concentration on 40 patients who had a delay of 72 hours or more from initial symptoms to operation. The initial medical contact points for patients were walk-in clinics and community emergency departments. Definitive care was provided in a general hospital. Patients were adults with appendicitis who underwent an operation for definitive management 72 or more hours after the onset of symptoms. Length of hospital stay, reasons for delay in diagnosis, incidence of perforation, and complications were recorded. Delay in diagnosis and treatment was attributed to factors controlled by the patient in 15 cases (27.5%) and by the physician in 25 cases (62.5%). Perforation, postoperative complications, and hospital length of stay were related to the delay in diagnosis; with delay, the mean hospital length of stay was 9 days, the incidence of perforation was 90%, and major complications were recorded in 60% of the patients. Early diagnosis and surgical management for appendicitis remains an important and, at times, elusive goal. Delays of 72 hours or more have serious consequences. Patient education and the experience, intuitiveness, and persistence of the physician are important elements to improving these findings.
