Appendicitis in Children: Does Age Really Matter?

Area of Science:

• Pediatric Surgery
• Emergency Medicine
• Clinical Diagnostics

Background:

• Acute appendicitis (AA) is a common surgical emergency in children.
• AA presents unique diagnostic challenges in younger pediatric populations.
• Understanding age-related differences in AA presentation is crucial for timely intervention.

Purpose of the Study:

• To compare clinical presentation, diagnostic scores, and outcomes of acute appendicitis in preschool versus school-aged children.
• To identify factors contributing to diagnostic challenges in younger children with AA.
• To evaluate the utility of diagnostic scores (PAS and Alvarado) in differentiating appendicitis severity across age groups.

Main Methods:

• Retrospective review of 402 pediatric patients (<16 years) with confirmed AA.
• Division into two groups: Group A (preschool, ≤5 years) and Group B (school-aged, >5 years).
• Comparative analysis of clinical symptoms, biomarkers, diagnostic scores (Pediatric Appendicitis Score [PAS], Alvarado score), and intraoperative findings.

Main Results:

• Preschool children (Group A) exhibited higher rates of fever, bowel disturbances, diffuse abdominal pain, and tenderness (P < 0.001).
• Group A showed significantly elevated white blood cell counts and C-reactive protein levels (P < 0.003).
• Higher mean PAS and Alvarado scores were observed in Group A, with a greater proportion scoring ≥8 (P < 0.001), and significantly higher rates of appendiceal perforation (77.3% vs. 41.5%, P < 0.0001).

Conclusions:

• Acute appendicitis in preschool children is characterized by atypical presentations and rapid disease progression.
• Early diagnosis of AA in preschool children is significantly more challenging.
• The findings underscore the need for heightened clinical suspicion and potentially modified diagnostic approaches for AA in very young children.
