Appendicitis is defined as "Acute inflammation of the appendix. Acute appendicitis is classified as simple, gangrenous, or perforated."[1]
The rates of unnecessary appendectomy and of perforation have not improved over time[2][3] in spite of increased use of laboratory tests[3] and diagnostic imaging[4].
Diagnosis
An Alvarado score (also called MANTRELS score) of less than 3[5] or 5[6] makes appendicitis very unlikely:
Two points each:
- Abdominal pain that migrates to the right iliac fossa
- Leukocytosis (more than 10000 white blood cells per microliter)
One point each:
- Anorexia (loss of appetite) or ketones in the urine
- Nausea or vomiting
- Pain on pressure in the right iliac fossa
- Rebound tenderness
- Fever of 37.3 °C or more
- Left shift or an increase in the number of immature leukocytes in the peripheral blood
Complications
Abscess
Appendiceal abscess or phlegmon occurs in 4% of cases.[7] It is controversial whether these patients require and appendectomy.[7]
