Acute appendicitis in children under 3 years of age. Diagnostic and therapeutic problems.

AIM: Analysis of diagnostic and therapeutic problems in acute appendicitis in children below 3 years of age.

MATERIAL AND METHODS: The analysis was based on medical data of 53 children under 3 years of age, treated in our department for acute appendicitis in the years 1988-2008. Among 53 children, 29 (53.7%) were admitted directly to the surgical department and 24 (45.3%) were transferred from the regional pediatric department. In the period of 1 month before admission to the surgical department 13 patients (24.5%) were treated as outpatients due to acute respiratory or alimentary tract infection. On the basis of the data from the case histories, the most frequent symptoms and their duration were evaluated, as well as the clinical signs, intraoperative diagnosis and the postoperative course.

RESULTS: The most frequent symptoms and clinical signs in this group of children were: abdominal pain, vomiting and fever, present in 83.0%, 75.5%, and 67.0% patients respectively. The mean time of the symptoms' duration was 3.6 days. The most frequently found physical signs on admission to the surgical ward were: abdominal pain on palpation, increased tonus of abdominal muscles and abdominal distension. On laparotomy gangrenous appendicitis was found in 49% of the children operated. In 24.5% of patients perforation of the appendix was confirmed. Further complications occurred in 9 children (16.9%). The average stay in hospital after the operation lasted 7.9 days.

CONCLUSIONS: 1. Acute appendicitis in small children is a diagnostic problem not only for primary health care doctors but also for experienced pediatricians and pediatric surgeons. 2. Early surgical consultation should be a standard procedure in small children with acute symptoms of various locations when there is accompaning abdominal pain, not reacting to conservative treatment. Surgical consultation is also indicated in children under 3 years of age with relapses of abdominal pain. 3. Clinical signs of appendicitis in children aged less than 3 years, may differ from those in older children due to changes in their immunological reactivity. This problem should be included in under-graduate and post-graduate medical studies.
