Surgery for Appendicitis

Your side may hurt so much that you call your healthcare provider. Or maybe you go straight to the hospital emergency room. After your evaluation, your healthcare provider may decide that you have appendicitis. If so, you will need surgery. Your provider will send you to a hospital room or take you right to the operating room. There your healthcare team will get you ready for surgery.

Your experience

You may have fluids and antibiotics through an IV (intravenous) line. Tell your healthcare provider if you are allergic to any antibiotics or other medicines. Before surgery, an anesthesiologist or nurse anesthetist will also talk with you. He or she will give you general anesthesia just before your appendectomy. This keeps you pain-free and lets you sleep during the surgery.

During surgery

The goal of surgery is to remove your appendix safely. In most cases, the surgery lasts from 30 minutes to an hour. If your appendix has burst, bacteria will be released into the belly (abdominal) cavity. Then surgery may take longer. Your surgeon may use 1 of 2 methods to reach your appendix. Your surgeon will discuss which is best for you:

  • Open surgery. Your surgeon makes 1 large cut (incision) in your lower right side. He or she makes a bigger incision if your appendix has burst.

  • Laparoscopic surgery. Your surgeon makes from 2 to 4 small incisions. One is near your belly button. The others are in other parts of your stomach. Your surgeon puts a thin tube with a camera attached (laparoscope) through one of the incisions. The camera shows the inside of your belly on a screen. This image helps guide the surgery. Your surgeon puts surgical tools into the other incisions.

Sometimes if the appendix has burst and a pocket of infection has formed, this will be drained. Antibiotics are given for some time (perhaps weeks) before the appendix is removed. 

Finishing the surgery

In most cases, the surgeon closes the entire incision with stitches or staples. Your surgeon may place a short-term (temporary) drain in the wound or in your belly. This helps cure or prevent infection. If your appendix burst, your surgeons may leave the outer layers of your incision open. Leaving the skin open prevents infection from forming under the skin. It may heal on its own. Or it may be closed about 5 days later.


Most people recover quickly after an appendectomy. You will likely be in the hospital for 1 to 2 days. If your appendix burst, you may stay longer. After you return home, plan on a follow-up visit to the healthcare provider in 1 to 2 weeks.

In the hospital

In most cases, you will drink fluids and walk on the day of your surgery. You will also have pain medicine. To help keep your lungs clear, a healthcare provider may teach you how to do breathing exercises.

Back at home

To help control pain from surgery, take your medicines as directed. Don't do any strenuous activity, heavy lifting, or driving until your surgeon says it is OK. As instructed, slowly go back to your normal activities in 7 to 10 days. If you are constipated, take fiber or a stool softener.

Risks and possible complications

Risks and complications can include the following:

  • Infection or bleeding from the incision site

  • Infection or swelling in the belly, or stool leakage

  • Delayed return of bowel or intestinal function (bowel ileus) or bowel blockage

  • Problems from anesthesia

Call your healthcare provider

Call your healthcare provider if you have any of the following:

  • Swelling, oozing, worsening pain, or abnormal redness around the incision

  • Fever of 100.4°F (38°C) or higher, or as directed by your healthcare provider   

  • Belly pain that gets worse

  • Severe diarrhea, bloating, or constipation

  • Nausea or vomiting

  • Trouble breathing or shortness of breath

  • Leg swelling
