Appendicitis
Appendicitis is a condition characterised by inflammation of the appendix.
Causes
It is possible for matter to become lodged in the appendix, leading to bacterial infection, which can cause appendicitis. If the condition is untreated, the appendix can turn gangrenous and can eventually burst, leading to peritonitis, septicemia and eventually death.
Signs, symptoms and examination findings
The pain of appendicitis usually starts centrally before localising to the right iliac fossa (the lower right side of the abdomen). There is usually associated anorexia (loss of appetite). Fever is usually present. Nausea, vomiting and diarrhea may or may not occur.
There is typically pain and tenderness in the right iliac fossa. Rebound tenderness may be present suggesting that there is some element of peritoneal irritation. If the abdomen is guarded, there should be a strong suspicion of peritonitis requiring urgent surgical intervention.
Diagnosis
Diagnosis is based on history and physical examination backed by blood tests and other diagnostic procedures.
The classical physical finding in appendicitis is maximum tenderness at McBurney's point, which is located on the right-hand side one-third of the distance between the hipbone and the navel, or approximately one hand's width. Other methods include a digital rectal exam, where a finger is inserted into the rectum to press on the appendix, a sharp pain meaning that the patient as appendicitis.
Treatment
Appendicitis can be treated by removal of the appendix through a surgical procedure called an appendicectomy (also known as an appendectomy).
Antibiotics are given intravenously to help kill remaining bacteria and thus reduce the inflammation.
