§1 · What it covers

This guideline covers diagnosis, operative/nonoperative treatment, timing of appendectomy, lavage, drains, postoperative antibiotics, and interval appendectomy.

Applies to: Adults and children; adult recommendations are directly relevant here.

§2 · Key recommendations

Ultrasound is a reasonable first-line study because it avoids radiation.
.
CT/MRI are most definitive (expert opinion).
For uncomplicated adult appendicitis, the panel suggests operative management (conditional.
low certainty).
For complicated adult appendicitis, it suggests operative management (conditional.
very-low certainty).
Either immediate (<12 h) or delayed (>12 h) operation is acceptable (conditional.
very-low certainty).
For perforated/complicated disease, either suction-and-lavage or suction alone is acceptable.
no routine drain is suggested.
short-term postoperative antibiotics are suggested.
Adult patients with complicated appendicitis successfully treated nonoperatively are suggested to undergo interval appendectomy (conditional.
low certainty).
