NHS Appendectomy: Appendix Removal Surgery
An appendectomy is the surgical removal of the appendix, typically performed as an emergency operation for acute appendicitis. It is one of the most common emergency abdominal surgeries performed in UK hospitals. Early diagnosis and treatment is essential — an untreated inflamed appendix can rupture, causing life-threatening infection.
- Urgency: Usually an emergency procedure (within hours)
- Surgical approach: Laparoscopic (keyhole) in most cases; open in some
- Operation time: 1–2 hours
- Hospital stay: 2–3 days (uncomplicated); longer if ruptured
- Return to normal activity: 4–6 weeks (laparoscopic); 6–8 weeks (open)
Symptoms of Appendicitis
Classic appendicitis symptoms develop over 12–24 hours and include:
- Pain beginning around the navel, moving to the lower right abdomen (McBurney’s point)
- Nausea and vomiting
- Fever (typically 37.5–38.5°C)
- Loss of appetite
- Abdominal swelling and tenderness to touch
- In some cases: diarrhoea or difficulty passing wind
Symptoms can vary considerably — not everyone has the classic pattern. Children and elderly patients in particular may present differently. If you are concerned, always seek prompt medical evaluation.
The Operation
Most NHS appendectomies are now performed laparoscopically (keyhole surgery). Under general anaesthetic, three small incisions allow the surgeon to insert a camera and instruments to remove the appendix. Open surgery (a larger incision) may be needed if the appendix has ruptured or complications arise.
Recovery
- Gradual return to normal activities over 2–4 weeks (laparoscopic)
- Avoid heavy lifting and strenuous exercise for 4–6 weeks
- Most people can return to desk work within 1–2 weeks
- The appendix is not needed for normal bodily function — life after appendectomy is completely normal

Frequently Asked Questions
How long does appendix removal (appendectomy) surgery take?
A laparoscopic (keyhole) appendectomy typically takes 30–60 minutes under general anaesthetic. Open surgery may take longer. Most patients who have keyhole surgery can go home within 24–48 hours; open surgery may require 3–5 days in hospital.
How long is recovery after an appendectomy?
Recovery from keyhole surgery is usually 2–4 weeks before returning to normal activities. Open surgery recovery takes 4–6 weeks. You should avoid heavy lifting and strenuous exercise for at least 4–6 weeks, or until cleared by your surgical team.
What are the signs that an appendix has burst?
Signs of a ruptured appendix include sudden brief relief of pain followed by more widespread abdominal pain, high fever, abdominal rigidity, nausea, and vomiting. A burst appendix is a medical emergency — call 999 or go to A&E immediately.
