There are two surgical treatment options for children with ruptured appendicitis. Early appendectomy is one option and typically involves removing the ruptured appendix after several hours of optimizing the patient medically with intravenous fluids and intravenous antibiotics. Another option, interval appendectomy, uses the same initial fluid and antibiotic management, but delays removing the appendix until 6-8 weeks later. The rationale for delaying the appendectomy is to perform the operation at a time when the patient is perhaps more stable and the abdominal cavity is free from contamination. Both of these treatment options are currently used by many pediatric surgeons across the United States and both appear to work well. The two treatment have never been compared in any prospective study. The primary outcome of the study is the time that a patient (and family) is away from normal activities, due to the disease and its treatment. Secondary outcome measures include complication rates, quality of life measures (SF10), hospital cost analysis, and others.
