Acute appendicitis: risk scores, imaging and the choice between antibiotics and appendicectomy

Acute appendicitis for FRCS (Gen Surg): Alvarado, AIR and Adult Appendicitis scores, imaging by patient group, antibiotics or surgery, and the appendix mass.

Appendicitis is a clinical diagnosis. Scores sort patients into low, intermediate and high risk; they do not replace judgement.
In UK adults aged 16–45 the RIFT study found the Adult Appendicitis Score best identified low-risk women and the AIR score low-risk men.
Ultrasound comes first in children, young women and pregnancy, with MRI as the second test in pregnancy; CT is the most accurate test in other adults.
