Which scoring system uses CT morphology, CRP, and clinical parameters to differentiate complicated (perforation/abscess) from uncomplicated acute appendicitis pre-operatively?

• A AAST appendicitis grade ✓
• B Alvarado score
• C RIPASA score
• D Adult Appendicitis Score (AAS)

Explanation

The AAST (American Association for the Surgery of Trauma) Appendicitis Grade uses CT findings to grade appendicitis severity from Grade 1 (no perforation, non-gangrenous) to Grade 5 (perforation with diffuse peritonitis), guiding operative vs non-operative decision-making. Alvarado and RIPASA are clinical prediction scores without imaging components. The Adult Appendicitis Score uses CRP, white cell count, and clinical parameters but not CT morphology specifically for complication prediction.
