Appendectomy — removal of the appendix — is one of the most common emergency surgical procedures. Prompt surgery prevents life-threatening perforation.
Appendectomy is the surgical removal of the appendix — a small, finger-shaped pouch attached to the large intestine in the lower right abdomen. It is the standard treatment for acute appendicitis — inflammation of the appendix, which if untreated progresses to perforation, peritonitis, and potentially life-threatening sepsis. Appendicitis presents with central abdominal pain migrating to the right lower quadrant, nausea, vomiting, and fever.
In Korea, emergency appendectomy is available 24/7 at university hospital emergency departments and general hospitals nationwide, reflecting Korea's dense network of accessible acute-care facilities. The vast majority of appendectomies are now performed laparoscopically (keyhole surgery) — using 3–4 small incisions, a camera, and instruments inserted through ports. Laparoscopic appendectomy offers faster recovery, lower complication rate, and better cosmetic outcome compared to open surgery. Open appendectomy is used when the appendix has perforated with peritonitis, or when laparoscopic approach is not feasible.
Recovery from uncomplicated laparoscopic appendectomy is rapid — most patients are discharged within 24 hours and return to light activities within 1–2 weeks. No dietary restrictions apply after discharge. The role of non-operative treatment (antibiotics alone) for uncomplicated appendicitis is being studied — while some cases resolve with antibiotics, recurrence risk is significant, and surgery remains the standard of care in Korea. If an appendix has perforated, longer hospital stay and IV antibiotics are required before discharge.
Key Points
- Appendicitis: right lower abdominal pain + fever + nausea = emergency assessment
- Laparoscopic appendectomy: keyhole surgery, faster recovery, most common approach
- Available 24/7 at hospital emergency surgical teams nationwide
- Hospital stay: 1 night for uncomplicated; longer for perforated appendicitis
- Return to light activities: 1–2 weeks; strenuous exercise: 4–6 weeks
- Do not eat/drink if appendicitis suspected — surgery may be needed
When to See a Doctor
- Severe right lower abdominal pain, fever, and nausea — go to the nearest emergency department immediately
- Do not take painkillers before assessment — may mask diagnostic signs
