Appendicitis

Appendicitis is a sudden inflammatory disorder of the vermiform appendix. The most common cause of appendicitis is an obstruction in the lumen, which can result from fecaliths, lymphoid hyperplasia, foreign substances, or, in rare cases, neoplasms. Obstruction raises the pressure inside the lumen, which causes bacteria to multiply too much, ischaemia, and then inflammation. If not treated, it could get worse and turn into gangrene, perforation, peritonitis, or an abscess.

Appendicitis usually shows up in the clinic as pain around the belly button that moves to the right lower quadrant (McBurney's point). Other symptoms include loss of appetite, nausea, vomiting, low-grade fever, and leukocytosis. Rebound tenderness and guarding are prominent signs that doctors look for. In complicated situations, there may be diffuse stomach pain and symptoms of sepsis.
A clinical evaluation, along with blood tests and imaging tests like an ultrasound or a contrast-enhanced CT scan, is used to make a diagnosis. To avoid perforation, it is essential to find it early.

Standard care entails the expeditious surgical excision of the inflamed appendix via appendectomy, performed either through an open or laparoscopic approach. In a few straightforward instances, conservative antibiotic treatment may be contemplated. With prompt intervention, the prognosis is often favourable. Delayed treatment greatly raises the risk of illness, especially in children and older adults.
