Ah, the classic "bread and butter" of general surgery! Appendicitis is a staple for the UKMLA AKT, so let's make sure you've got this down pat. It's one of those topics where clinical intuition meets scoring systems to decide who goes to theatre.

I'll start by pulling up some high-yield lessons that cover the essentials for your exam.

The clinical presentation of appendicitis is often described as a "classic" progression, but remember that in the AKT, they love to throw in atypical presentations (like a retrocaecal appendix causing flank pain).

Key Clinical Features:

• Migratory Pain: Typically starts as vague periumbilical pain (visceral) and then localises to the Right Iliac Fossa (RIF) (somatic) as the parietal peritoneum becomes irritated.
• Anorexia: Often called the "hamburger sign"—if the patient is hungry, it's less likely to be appendicitis!
• Nausea and Vomiting: Usually occurs after the onset of pain.
• Low-grade Fever: High fevers might suggest perforation or an alternative diagnosis like mesenteric adenitis.

There are several specific signs we look for on examination. Let me find a diagram to help you visualise McBurney's point and these clinical signs.
