Home Intravenous Versus Oral Antibiotics Following Appendectomy for Perforated Appendicitis in Children, a Randomized Controlled Trial

Appendicitis is the most common cause of abdominal pain requiring emergent surgical intervention in children and approximately one third of patients present with perforation. Perforated appendicitis has been demonstrated to have a significant impact on patients and families due to the prolonged hospitalization, high complication rates, and tremendous economic burden from treatment. The most significant complication following operative treatment of perforated appendicitis is intra-abdominal abscess, which develops in approximately 20% of children following appendectomy in recent literature. Due to this frequent and morbid complication, continued research has been driven at determining the most efficacious and cost-effective postoperative antibiotic treatment regimen to reduce post-operative abscess. As postoperative abscess rates following appendectomy for perforated appendicitis remain high, the primary aim of this study was to evaluate a new postoperative antibiotic treatment regimen based on single daily dosing ertapenem while inpatient with randomization into ten day completion course of home antibiotics with IV ertapenem versus oral amoxicillin/clavulanate. The hypothesis is that the ertapenem based regimen will offer reduced rates of postoperative abscess, with no major difference between completion courses of home IV versus oral antibiotics.
