Q

what is the pathophysiology of appendicitis?

A

Lumen of appendix is obstructed => fills with mucus => increased pressure => bacteria multiply (bacteriodes fragilis and E.coli) => distension of lumen => inflammation, oedema, ischaemia, necrosis, perforation => nausea, vomiting, pain, reflex anorexia
