The primary objective of this study is to determine: conversion to surgery (failure of nonoperative management), 30 day, 6 month and 1 year recurrence rate of appendicitis in children treated with non-operative management. Recurrence is defined as need for appendectomy. The secondary objective is to compare adverse outcomes, length of stay, days to return to school, costs of care and quality of life measures between the study group and those that receive standard of care.We hypothesize that non-operative management of early appendicitis in children with antibiotics alone will be successful in 80% of children at 1 year follow-up.
