Overview

An open appendectomy is surgery to remove the appendix through a single incision in the lower right abdomen. It is done under general anesthesia. The surgeon identifies and removes the appendix and closes the incision with sutures or staples. This approach may be chosen when the appendix has ruptured, there is an abscess, there is significant scarring, or when laparoscopy is not suitable. Removing the appendix treats appendicitis and helps prevent complications like infection inside the abdomen.

Preparation & Next Steps

Everything you need to know before and after your procedure

Before Care

  • Expect evaluation with labs and imaging such as ultrasound or CT to confirm appendicitis
  • Follow hospital fasting instructions before anesthesia, including when to stop food and liquids
  • Bring a current list of medicines and allergies; include blood thinners and supplements
  • Ask how to handle blood thinners, diabetes medicines, and inhalers before surgery
  • Arrange a ride home and help for the first day after anesthesia
  • Do not shave the surgical area at home; the team will prepare the skin if needed
  • Remove jewelry and nail polish; wear loose, comfortable clothing
  • Bring a photo ID, insurance card, and any medical devices you use, such as a CPAP

  • Confirm a preferred pharmacy and an emergency contact for updates

After Care

  • You may be able to shower after a short period; avoid soaking the incision until cleared
  • Take prescribed medicines as directed by your care team; do not drive while taking opioids

  • Use deep breathing or an incentive spirometer if provided to protect lung function
  • Eat small, easy-to-digest meals and drink fluids; ask about options if constipation occurs
  • Avoid heavy lifting and strenuous activity until your surgical team says it is safe
  • Check the incision daily for increasing redness, swelling, warmth, drainage, or opening

Frequently Asked Questions

Common questions and expert answers about this procedure

What is the difference between open and laparoscopic appendectomy?

Open surgery uses one larger incision in the lower right abdomen. Laparoscopic surgery uses several small incisions with a camera. Open surgery may be chosen when there is rupture, abscess, or extensive scarring.

How long is the hospital stay?

Many people go home within 1 to 3 days. A longer stay may be needed if the appendix ruptured or if antibiotics and drains are required.

Will I have a drain?

A drain may be placed if there is significant infection or an abscess. It is usually removed when drainage decreases and the team decides it is safe.

What will the scar look like?

You will have a single incision on the lower right abdomen. Over time it usually fades, but appearance varies with skin type, healing, and sun exposure.

When can I eat after surgery?

Clear liquids are often started first and then solid foods are added as bowel function returns and nausea improves.

Can appendicitis be treated with antibiotics only?

Some uncomplicated cases can be managed with antibiotics, but many people still need surgery, and antibiotics are standard when rupture or abscess is present.

What happens after the appendix is removed?

You can live a normal life without the appendix. The removed tissue is typically sent to a lab for examination.

When can I return to sports or heavy work?

Strenuous activity is usually restricted for several weeks after open surgery. Your surgical team will give timing based on healing and job or sport demands.
