Acute appendicitis Flashcards
What is appendicitis
Inflammation of the appendix (arising from caecum)
Appendicitis pathophysiology
Pathogens can get trapped due to obstruction at the point where the appendix meets the bowel. Results in infection and inflammation.
Can lead to gangrene and rupture
Appendicitis presentation
10-20yrs

Rovsing’s sign +ve
Loss of appetite

Low grade fever
Abdo guarding on palpation
Rebound (and percussion) tenderness in RIF (can also indicate peritonitis)
Appendicitis differentials
Ectopic pregnancy
Ovarian cysts
Meckel’s diverticulum
Mesenteric adenitis (inflamed abdominal lymph nodes)
Appendicitis investigations
hCG to exclude pregnancy
USS or CT if old

Mainly diagnosed through history and examination
Appendicitis management
Emergency admission under surgical team
Appendicectomy
Appendicitis complications
Peritonitis Perforation Sepsis Wound infection, pain, bleeding and scars Damage to bowel, bladder or other organs Removal of a normal appendix Anaesthetic risks VTE
