Appendix

What is Appendix?

Swelling of the appendix when it is inflamed, obstructed or infected is called appendicitis. The appendix is a small, tube-shaped pouch attached to the large intestine on the lower right side of the abdomen.

What is the function of appendix ?

It has no major function in adults, its a vestigeal organ.

What are the symptoms of appendicitis?

Common appendicitis symptoms include:

  • Pain that begins near the belly button and shifts to the lower right abdomen
  • Fever
  • Loss of appetite
  • Nausea or vomiting
  • Abdominal bloating
  • Pain worsening during walking, coughing, or sneezing

If you experience sudden severe abdominal pain, seek immediate gastroenterology consultation.

What causes appendicitis?

Appendicitis occurs when the appendix is blocked by:

  • Stool (fecalith)
  • Mucus

Infection
This blockage leads to bacterial growth, resulting in swelling, inflammation, and sometimes rupture.

How is appendicitis diagnosed?

Doctors may use:

  • Physical examination to check tenderness in the lower right abdomen
  • Blood tests to detect infection
  • Ultrasound or CT scan to confirm the diagnosis
  • Urine tests to rule out urinary tract issues

What happens if appendicitis is not treated?

If left untreated, the appendix can burst, leading to a serious infection (peritonitis) or abscess formation, which can be life-threatening and needs emergency care.

What is the treatment for appendicitis?

The main treatment is surgical removal of the appendix, known as an appendectomy. It can be done through:

  • Laparoscopic surgery (keyhole method with faster recovery), or
  • Open surgery, if the appendix has ruptured or infection has spread.

In mild cases, antibiotics may be given before surgery or, rarely, as the only treatment.

Is appendicectomy a major surgery ?

No, it is not a life threatening major surgery. Though done under general anaesthesia, it is not a major surgery. 

How many days of hospital stay is needed for appendicectomy ?

In early cases, 1-2 days of hospital stay is enough including a day of surgery. 

In complications like perforation or rupture of appendix or abscess formation, recovery may be delayed and patients may have to stay a few more extra days in the hospital.

Is digestion affected because of removing the appendix?

No, digestion is not affected as the appendix has no role in digestion and it is a vestigeal organ.
