Severity of appendicitis correlates with the pediatric appendicitis score

Purpose The pediatric appendicitis score (PAS) has been used as a diagnostic tool for the assessment of acute abdominal pain. Our institution has utilized this scoring system as part of a clinical pathway for acute appendicitis. We sought to discover if the PAS could also serve as a prognostic indicator. Methods Patients treated within the clinical pathway were divided into three groups (A, B, and C) based on the PAS assigned on admission. Data pertaining to intraoperative findings and length of hospital stay were collected prospectively. Results In 4 months, 112 patients were enrolled in the study (median age 10.5, range 1-18). 69 of these patients underwent early laparoscopic appendectomy. For group A, 75% had simple appendicitis and 5% were complex. For group B, 68.4% patients had simple appendicitis and 26.3% were complex. For group C, 27.3% were simple and 63.6% were complex. Mean length of hospital stay increased from 1.63 ± 0.34 for patients in group A to 5.9 ± 1.37 for patients in group C. Conclusion Our observational data suggests that the PAS may be a prognostic tool for acute appendicitis. It thereby may impact on preoperative management and postoperative clinical pathways. A larger cohort is necessary to validate our findings.
