Appendicitis in children less than 5 years old: influence of age on presentation and outcome

PURPOSE: Appendicitis is the most common emergency surgical condition of the abdomen in children. This study sought to delineate the presentation and the outcome of appendicitis in children younger than 5 years old. METHODS: A retrospective review was conducted of all children younger than 5 years of age who underwent appendectomy for acute appendicitis over a 12-year period. RESULTS: One thousand eight hundred thirty-six patients younger than 19 years of age underwent appendectomy. Two hundred eighty-one children with an age range of 6 months to 4.9 years were included in this study. Perforation rates were higher in the younger patients (86% <1 year, 74% 1-1.9 years, 60% 2-2.9 years, 64% 3-3.9 years, and 49% 4-4.9 years), but the youngest children had fewer postoperative abscesses. CONCLUSIONS: In children less than 5 years old with appendicitis, age has a direct correlation to the stage of disease. The youngest children present with more advanced appendicitis but are less likely to develop postoperative abscesses. (C) 2012 Elsevier Inc. All rights reserved.
