An appendectomy is a surgical procedure to remove the appendix, a small, finger-shaped pouch attached to the large intestine. It is the standard and most effective treatment for appendicitis, a condition in which the appendix becomes inflamed, infected, and potentially life-threatening if not treated promptly.

What Is Appendectomy?

An appendectomy is surgery to remove the appendix when it becomes inflamed or infected. Appendicitis is a medical emergency, because a swollen appendix can burst (rupture), spreading infection inside the abdomen.

Appendectomy can be performed as:

• Emergency surgery, which is most common
• Urgent or planned surgery, in selected cases where inflammation is mild and controlled initially

Once the appendix is removed, it does not affect digestion or long-term health.

Why Is an Appendectomy Needed?

Appendectomy is performed to treat appendicitis, which occurs when the appendix becomes blocked by:

• Stool
• Infection
• Swelling of lymph tissue
• Rarely, a tumour

This blockage leads to:

• Bacterial growth
• Inflammation
• Increased pressure
• Risk of rupture

When an appendix becomes highly inflamed or when it bursts, it can cause peritonitis (serious abdominal infection) or abscess formation, making surgery and recovery more complex.

Types of Appendectomy

Laparoscopic Appendectomy

Laparoscopic surgery is the most common approach today.

How it is done:

• The surgeon makes 2–3 small incisions in the abdomen
• A camera (laparoscope) provides a magnified internal view
• Special instruments are used to remove the appendix

Advantages:

• Smaller scars
• Less pain after surgery
• Lower infection risk
• Faster recovery
• Shorter hospital stay

Most patients can return to normal activities sooner after laparoscopic surgery.

Open Appendectomy

Open surgery may be required when:

• The appendix has already burst
• There is widespread infection
• There is severe scarring or complications
• There is difficulty in removing the appendix when due to adhesions with surrounding bowel.

How it is done:

• A single larger incision is made in the lower right abdomen
• The appendix is removed directly

In some cases, surgeons may start laparoscopically and convert to open surgery.

Preparing for an Appendectomy

Before Surgery

Appendectomy is often performed soon after diagnosis, especially in emergency cases.

Before surgery, your doctor may:

• Perform a physical examination

• Order imaging tests such as:

  • CT scan
  • Ultrasound

• Review blood test results

You will also be asked about:

• Past medical conditions
• Previous surgeries
• All medications and supplements you take
• Drug or food allergies
• Bleeding disorders

Eating and Drinking

You will usually be asked to fast (not eat or drink) before surgery. The healthcare team will give clear instructions.

Preventing Infection

• Antibiotics are usually given before surgery
• You may be asked to wash with a special antiseptic soap

What Happens During an Appendectomy?

Step-by-Step Overview

• An IV line is placed to give fluids and medications
• General anesthesia is used, so you are fully asleep
• A breathing tube may be placed temporarily
• Vital signs are monitored throughout the procedure
• The surgeon removes the appendix

If the appendix has burst:

• The abdomen is carefully cleaned

• A drain may be placed in rare cases

• Incisions are closed and covered with sterile dressings

Surgery duration: Usually 30 to 60 minutes

What Happens After Surgery?

In the Recovery Room

After surgery:

• You are monitored as anesthesia wears off
• Mild grogginess, nausea, or sore throat is common
• Pain relief medications are provided

Hospital Stay

• Many patients go home the same day or within 1–2 days

• Longer stays may be needed if:

  • The appendix ruptured
  • There was infection or abscess

Recovery at Home

During recovery:

• You will be encouraged to walk early, which helps healing
• Start with clear liquids, then progress to solid foods
• Pain usually improves over several days
• Dressings should be kept clean and dry

Most people:

• Resume light activities within a few days
• Return to work or school within 1–2 weeks (laparoscopic)
• Need more time after open surgery or rupture

Risks and Complications of Appendectomy

Appendectomy is a safe and commonly performed surgery, but like all operations, it carries some risks.

Possible Complications Include:

• Bleeding
• Wound infection
• Injury to nearby organs
• Leakage of bowel contents into the abdomen
• Abscess (collection of pus)
• Ileus (temporary slowing of bowel movement)

The risk of complications is higher if the appendix has burst before surgery.

When Should You Call the Doctor?

After going home, contact your doctor if you develop:

• Fever
• Increasing abdominal pain
• Redness, swelling, or discharge from the incision
• Persistent vomiting
• Difficulty passing gas or stool

Prompt follow-up helps prevent serious complications.

Life After Appendectomy

Once healed:

• You can live a normal, healthy life
• There are no dietary restrictions
• The appendix does not need to be replaced

Most patients feel significant relief once the inflamed appendix is removed.
