Laparoscopic Appendectomy

Appendectomy is the removal of the appendix, usually because it has become inflamed. It is often performed as an emergency, and frequently by keyhole surgery.

Why the appendix is removed

Appendicitis is inflammation of the appendix, a small pouch attached to the large intestine. Typical features include pain that often starts near the navel and moves to the lower right abdomen, loss of appetite, nausea and fever, though presentations vary, particularly in children, older adults and during pregnancy. Untreated appendicitis can lead to perforation and infection inside the abdomen.

Diagnosis is based on examination, blood tests and imaging such as ultrasound or CT. Some cases are treated with antibiotics rather than immediate surgery; the choice depends on the findings and the treating team's judgement.

Sudden, severe or worsening abdominal pain needs urgent medical assessment. Do not use this website to decide whether you have appendicitis.

How the operation is done

  1. General anaesthesia is given, usually soon after the decision to operate.
  2. Typically three small cuts are made.
  3. The appendix is identified, its blood supply sealed, and its base secured.
  4. The appendix is removed through one of the small cuts.
  5. If there is pus or perforation, the area is washed out, and a drain may be placed.

Conversion to open surgery may be needed if the appendix is difficult to reach, badly inflamed or if there is extensive infection.

Recovery in general terms

  • Uncomplicated cases often involve a short hospital stay; perforated or infected cases usually need longer and a course of antibiotics.
  • Diet is usually reintroduced gradually as advised by the team.
  • Wound soreness and tiredness are common in the first week or two; heavy activity is restricted for a period your surgeon will specify.

Risks to discuss with your surgeon

Along with the general risks described on our risks page, appendectomy carries risks including wound infection, collection of pus inside the abdomen (abscess), bleeding, injury to nearby bowel, prolonged ileus (slow return of bowel function), and, rarely, later adhesion-related problems.

Warning signs after discharge

Seek medical attention for fever, increasing abdominal pain, persistent vomiting, wound redness or discharge, or feeling generally unwell. The patient guide lists more warning signs and recovery pointers.
