The diagnostic difficulties result in increased risks of both negative appendectomies and a delayed diagnosis, both leading to increased morbidity, more complications, longer hospital stay, and higher costs. These risks are further increased in the younger children. The doctor delay is a known cause contributing to late diagnosis in young children. Other studies, with patients under 3 years and 4 years of age, have found parent delay to contribute as well to the late diagnosis. Our clinical experience, confirmed by the literature, shows that the younger children with acute appendicitis deviate from the typical presentation and clinical findings observed in older children with acute appendicitis.
