Objective: To investigate the influence of patient age on the diagnosis and management
of appendicitis, as well as to evaluate the rate of complications according
to the age group.Methods: We undertook a retrospective analysis of 1,736 children who underwent
laparoscopic appendectomy in our center between January 2000 and December
2013. Patients were divided in groups taken into account their age: group A
were infants, group B were preschoolers, group C were those ones older than
five years old, and group D were those ones younger than five years old. A p
value of 0.05 was considered statistically significant.Results: We found higher incidence of misdiagnosis and atypical symptoms in the
youngest patients. The rate of perforation was similar between group A and B
(p=0.17). However, it was higher in group D than in group C (p<0.0001).
The incidence of postoperative complications was higher in the youngest
patients too (p=0.0002).Conclusions: The age does make a difference in acute appendicitis. Because of its unusual
presentation in children younger than five years old, it is often
misdiagnosed, which leads to an increased morbidity. Although clinical
presentation varies between infants and preschoolers, no statistically
significant differences were observed in the rate of perforated appendix or
postoperative complications.
