Management of perforated appendicitis in children: a decade of aggressive treatment.

Perforated appendicitis in children continues to be associated with significant morbidity. In 1976, a treatment algorithm was begun at the authors' institution, which included immediate appendectomy, antibiotic irrigation of the peritoneal cavity, transperitoneal drainage through the wound, and 10-day treatment with intravenous ampicillin, clindamycin, and gentamicin. Initial results with this scheme in 143 patients demonstrated a 7.7% incidence of major complications and no deaths. From 1981 through 1991, the authors continued to use this treatment plan in all patients with perforated appendicitis. Three hundred seventy-three patients with perforated appendicitis were treated, and the rate of major complications was 6.4%. Infectious complications occurred in 18 patients (4.8%) and included intraabdominal abscesses (5 patients, 1.3%), phlegmon treated with an extended course of antibiotics (6 patients, 1.6%), wound infections (5 patients, 1.3%), and enterocutaneous fistula requiring further operations (2 patients, 0.5%). There were six cases of small bowel obstruction (1.6%), which required operative intervention. There were no deaths. The average length of stay for all patients was 11.4 days (range, 8 to 66 days). Utilization of transperitoneal drainage and choice of antibiotic therapy continue to be sources of controversy in the surgical literature. However, the treatment plan used in the present study resulted in the lowest complication rate reported to date, and the authors conclude that this scheme is truly the "gold standard" for treatment of perforated appendicitis. New treatment plans using laparoscopic appendectomy, different or shorter courses of antibiotics, or not using drains should have complication rates that are as low as, or lower than this one to be considered as useful alternatives.
