Appendicitis Overview

The appendix is a small, finger-shaped pouch attached to the lower right side of the abdomen's large intestine. Appendicitis, a medical emergency, occurs when the appendix becomes inflamed and filled with pus. Immediate treatment is necessary to prevent potential life-threatening complications from a ruptured appendix.
Symptoms
Abdominal Pain: The primary symptom of appendicitis is pain in the lower right abdomen, starting as a dull ache and intensifying with inflammation. It may radiate from the navel to the lower right abdomen.
Additional Symptoms: Worsening inflammation may lead to:
    • Loss of appetite
    • Nausea and vomiting
    • Constipation or diarrhea
    • Abdominal swelling
    • Hardening of the appendix area
  • Fever: A body temperature of 100.4°F (38°C) or higher is common as the body combats infection.

  • Variability of Symptoms: Symptoms and their severity can vary between individuals, and other conditions may present similarly. A doctor's evaluation for an accurate diagnosis is crucial.

Causes

The precise cause of appendicitis is unclear, but it's thought to result from blockages in the appendix, including:

  • Fecal impaction: Hardened stool buildup causing a blockage and subsequent inflammation.

  • Enlarged lymphoid follicles: Swollen lymphoid follicles leading to blockage, inflammation, and infection.

  • Worm infestation: Certain worms causing blockage, inflammation, and infection.

  • Trauma: Abdominal trauma, such as a blow or injury, inducing inflammation.

Diagnosis and Treatment

If appendicitis is suspected, prompt medical attention is crucial. Diagnosis involves:

  • Physical examination: Checking for tenderness in the lower right abdomen.

  • Pathological evaluation: Blood and urine tests to assess infection severity.

  • Imaging tests: CT scans or ultrasounds to visualize inflammation or infection in the appendix.

The standard treatment is an appendectomy, the surgical removal of the appendix. This can be an open surgery with a longer recovery period or a laparoscopic procedure requiring a shorter hospital stay and quicker recovery.

Complications

  • Ruptured Appendix: Untreated, an infected appendix may rupture, causing severe abdominal pain, fever, and vomiting.

  • Peritonitis: A ruptured appendix can spill bacteria and pus into the abdomen, leading to the severe infection peritonitis, requiring immediate treatment.

  • Abscess Formation: A ruptured appendix may result in an abscess, necessitating drainage through a needle or surgery.
