AbstractAppendicitis is the most common surgical abdominal emergency in the pediatric population, but is rarely considered in children less than 3 years of age. The goal of this study was to identify the presenting symptoms and signs in this age group and examine their subsequent management and outcome. A 28-year experience of a single pediatric surgeon in academic practice was reviewed; 27 children less than 3 years old (mean 23 months) comprised 2.3% of all children with appendicitis in his series. The most common presenting symptoms were vomiting (27), fever (23), pain (21), anorexia (15), and diarrhea (11). The average duration of symptoms was 3 days, with 4 or more days in 9 children. Eighteen children were seen by a physician before the correct diagnosis was made; 14 were initially treated for an upper respiratory tract infection, otitis media, or a urinary tract infection. The most common presenting signs were abdominal tenderness (27), peritonitis (24), temperature 38.0 degrees C or more (21), abdominal distension (18), Leukocytosis (<12.0 x 10(3)/mm(3)) was found in 18, tenderness was localized to the right lower quadrant (RLQ) in 14 and was diffuse in 10. Abdominal radiographs demonstrated findings of a small-bowel obstruction (SBO) in 14 of 21 patients, a fecalith in 2, and a pneumoperitoneum in 1. Contrast enemas were performed in 6 children, 5 of whom had a phlegmon or an abscess. Perforated appendicitis was found in all 27 patients. An appendectomy was performed in 25 and a RLQ drain was placed in 18. Postoperative antibiotics were administered to 17 children for an average of 6 days. Two patients underwent interval appendectomies, 1 following treatment with IV antibiotics and 1 following surgical drainage. The average time to resume oral intake was 7 days and the average hospital stay was 21 (median 15) days. Sixteen patients had 22 complications, which included 6 wound infections, 4 abscesses, 4 wound dehiscences, 3 pneumonias, 2 SBOs, 2 incisional hernias, and 1 enterocutaneous fistula. Perforated appendicitis was found in all children less than 3 years old, resulting in very high morbidity (59% complications), which may be attributed to the 3-5-day delay in diagnosis. Although appendicitis is uncommon in this age group, it should be seriously considered in the differential diagnosis of children under the age of 3 years who present with the triad of abdominal pain, tenderness, and vomiting.
