Quick Answer: What is an appendectomy?
An appendectomy is surgery to remove an inflamed or infected appendix, the small tube-shaped organ attached to the colon. It's the standard treatment for appendicitis and is usually done within 24 hours of diagnosis, laparoscopically or as open surgery. The operation takes an hour, both methods succeed more than 95% of the time, and full recovery takes six weeks.
What the research says
Antibiotics alone avoid surgery for many, but about 3 in 10 still need an appendectomy within a year. A Cochrane review of 13 randomized trials with 3,358 participants found that 30.7% of people treated with antibiotics for appendicitis needed an appendectomy within one year. Antibiotic treatment caused fewer wound infections than surgery. (Doleman et al., Cochrane Database of Systematic Reviews, 2024) [2]
Surgery is far more reliable in the long term. In a meta-analysis of 7 randomized trials with 3,164 adults with uncomplicated appendicitis, treatment worked at one year in 73.8% of the antibiotic group versus 98.1% after surgery. Antibiotics failed in up to 46% of people with an appendix stone (appendicolith). (Salman et al., Surgical Laparoscopy, Endoscopy & Percutaneous Techniques, 2026) [3]
Routine drains after complicated appendicitis show no proven benefit. A Cochrane review of 8 studies with 739 participants found no clear evidence that abdominal drains prevent abscesses after appendectomy for complicated appendicitis, and drains may lengthen the hospital stay by about 1.6 days. (Tang et al., Cochrane Database of Systematic Reviews, 2025) [4]
Key takeaways
An appendectomy removes the appendix and is the standard, definitive treatment for appendicitis. [1]
Most are done within 24 hours of diagnosis, because an inflamed appendix can burst within 36 hours of the first symptoms. [1]
Laparoscopic surgery uses small cuts and usually means faster recovery and less pain, while open surgery may be needed for advanced cases. [1]
Most people return to work or school in one to three weeks and recover fully in about six weeks. [1]
You can live a normal life without your appendix. [1]
What is an appendectomy?
An appendectomy is surgery to remove your appendix, a small, tube-like organ that extends from the colon on the lower right side of your belly. Surgeons have performed it for more than a century, and in the United States they do about 300,000 each year. [1]
It is the definitive treatment for appendicitis. A healthy appendix has no known essential function, so people do not miss it after it is removed. [1]
Why is an appendectomy done?
Appendicitis is a medical emergency. An inflamed appendix can burst (rupture) within 36 hours of the first symptoms and spread infection through the belly, causing peritonitis. If the infection reaches the bloodstream, it can cause life-threatening sepsis. [1]
Some people with mild, early appendicitis may be treated with antibiotics alone, but they face a higher chance of the infection coming back. [1] Research shows that about 3 in 10 people treated with antibiotics need surgery within a year, [2] and the risk of failure is higher when an appendicolith (appendix stone) is present. [3]
What are the types of appendectomy?
Laparoscopic and open appendectomy side by side.
Feature | Laparoscopic appendectomy | Open appendectomy |
Incisions | One to three small cuts near the belly button | One larger cut in the lower right belly |
Tools | Camera (laparoscope) and thin instruments | Direct view and standard instruments |
Recovery | Faster, with less pain | Longer; up to a month before work or school |
Best for | Most uncomplicated cases | Advanced cases or widespread infection |
Scar | Small scars | Scar about 3 inches (7.6 cm) long |

Laparoscopic surgery is the more common approach in the United States today. Your surgeon may switch to open surgery during the operation if there is widespread infection in the belly. Read more about keyhole surgery in our laparoscopy guide. [1]
How do you prepare for an appendectomy?
An IV line is placed so antibiotics can start right away. [1]
You may have more blood tests or imaging. [1]
Your care team reviews your medical history, medicines and allergies, explains the surgery and asks for your consent. [1]
You should not eat or drink for eight hours before surgery, and you receive fluids through the IV. [1]
You receive general anesthesia, with a breathing tube to protect your airway. [1]
What happens during an appendectomy?
The main stages of an appendectomy.
Laparoscopic appendectomy steps
The surgeon makes one to three small cuts near your belly button. [1]
A port and a small tube (cannula) go in through one cut. [1]
Your belly is inflated with carbon dioxide gas to create working room. [1]
A laparoscope (thin tube with a light and camera) shows the surgery on a screen. [1]
The appendix is tied off with stitches, separated from the colon and removed. [1]
The cuts are closed. [1]
Open appendectomy steps
The surgeon makes one larger cut in the lower right belly. [1]
The appendix is found and any infection is drained. [1]
The belly is rinsed with sterile saline. [1]
The appendix is tied off and removed. [1]
The cut is closed with stitches. If peritonitis is present, a drainage tube may be left in place for a while. [1]
The average appendectomy takes about one hour. [1]
What happens after an appendectomy?
After uncomplicated laparoscopic surgery, you may go home the same day, but someone needs to drive you. If your appendix burst or you had open surgery, you may stay in the hospital for a few more days for IV antibiotics and monitoring. [1] Antibiotics usually continue for one to seven days after surgery, depending on how severe the infection was. [1]
Some pain afterward is normal and usually improves within a few days. Nausea, constipation, gas pain and bloating are also common in the first days. [1]
How long is appendectomy recovery?
A typical recovery timeline after appendectomy.
Time after surgery | What to expect |
Surgery day | Home the same day after uncomplicated laparoscopic surgery |
First few days | Pain, nausea, gas and bloating ease |
1 to 3 weeks | Back to work or school; up to a month after open surgery |
2 to 3 weeks | Follow-up visit with your provider |
About 6 weeks | Full recovery |
Sources: [1]
Recovery do's and don'ts
Keep your cuts clean and dry, and do not bathe or swim until your provider says it is safe. [1]
Start with soft foods and add more as your bowels tolerate them. [1]
Walk regularly to prevent blood clots and help your bowels work. [1]
Avoid heavy lifting, straining and climbing many stairs. [1]
Take only medicines your provider approves, because some pain relievers can increase bleeding. [1]
What are the risks of an appendectomy?
Complications are rare. [1]
Risk | What it means |
Bleeding | Blood loss during or after surgery |
Wound infection | Redness, swelling or pus at a cut |
Blocked bowel | The intestines stop moving food and gas normally |
Injury to nearby organs | Accidental damage to nearby structures |
Sources: [1]
When should you call a doctor after an appendectomy?
Call your provider right away if you notice signs of infection: [1]
Fever [1]
Swelling or discoloration around a cut [1]
Pus around a cut [1]
Stomach cramps [1]
Loss of appetite [1]
Conclusion
An appendectomy is the standard, highly successful treatment for appendicitis. Most people have laparoscopic surgery, go home quickly and recover fully in about six weeks, while open surgery is used for more advanced cases. [1]
Antibiotics alone can work for some people with mild appendicitis, but many still need surgery later. [2] [3] If you have sudden pain in the lower right belly, get medical care quickly, because early treatment helps prevent a rupture. [1]
