Appendicitis in children: A systematic approach for a low incidence of complications

Abstract

Four hundred fourteen appendectomies in children have been described. Acute nonperforated appendicitis was seen in 57.1 percent of the patients and perforated appendicitis in 18.6 percent. A histologically normal appendix was seen in 14.3 percent of the patients. In 31 of these patients, other pathologic abnormalities were found to account for the symptoms, thus the number of negative explorations was reduced to 7 percent. The average length of hospitalization was 5.3 days for patients with acute nonperforated appendicitis and 7.3 days for patients with perforated appendicitis. A protocol was followed which consisted of fluid resuscitation, preoperative and postoperative administration of antibiotics, and surgical exploration with appendectomy in all patients. No interval appendectomies were performed. The peritoneal cavity was not irrigated and the use of drains was avoided as much as possible. All wounds were closed primarily without wound drains. Topical cefamandole powder was used in all cases. Aerobic and anaerobic culture specimens were obtained in all cases from the peritoneal cavity and appendiceal stump. Twenty-eight different organisms were recovered, B. fragilis being the most common followed by E. coli. Excellent results were obtained without mortality and a less than 1 percent complication rate. There was a shorter period of hospitalization for patients with perforated appendicitis and a shorter period of antibiotic treatment.
