Endoscopic Total Extraperitoneal Hernia Repair


An endoscopic total extraperitoneal (TEP) hernia repair is surgery to repair an inguinal hernia.


The week before your surgery:

  • Write down the correct date, time, and location of your surgery.
  • Arrange a ride home. Ask a family member or friend to drive you home after your surgery or procedure. Do not drive yourself home.
  • Ask your caregiver if you need to stop using aspirin or any other prescribed or over-the-counter medicine before your procedure or surgery.
  • Bring your medicine bottles or a list of your medicines when you see your caregiver. Tell your caregiver if you are allergic to any medicine. Tell your caregiver if you use any herbs, food supplements, or over-the-counter medicine.
  • You may need to have an abdominal ultrasound or CT scan before your surgery. Talk to your caregiver about these or other tests you may need. Write down the date, time, and location for each test.

The night before your surgery:

Ask caregivers about directions for eating and drinking.

The day of your surgery:

  • Ask your caregiver before you take any medicine on the day of your surgery. Bring a list of all the medicines you take, or your pill bottles, with you to the hospital. Caregivers will check that your medicines will not interact poorly with the medicine you need for surgery.
  • You or a close family member will be asked to sign a legal document called a consent form. It gives caregivers permission to do the procedure or surgery. It also explains the problems that may happen, and your choices. Make sure all your questions are answered before you sign this form.
  • Caregivers may insert an intravenous tube (IV) into your vein. A vein in the arm is usually chosen. Through the IV tube, you may be given liquids and medicine.
  • An anesthesiologist will talk to you before your surgery. You may need medicine to keep you asleep or numb an area of your body during surgery. Tell caregivers if you or anyone in your family has had a problem with anesthesia in the past.


What will happen:

  • Your surgeon will make a small incision under your belly button. Your abdominal muscles will be secured to the sides of this incision. Your caregiver will make a tunnel under your skin and muscle to reach the area of your hernia. A device with a balloon may be put into your incision. The balloon will be inflated to create a space outside your peritoneum (the lining of your peritoneal cavity).
  • The balloon is then removed and the space may be filled with carbon dioxide gas. The gas will help your surgeon see the area in need of repair. One to 2 more small incisions may be made. A scope and other devices will be put through the incisions. Mesh is inserted to cover your weak muscles, and to push your tissues and organs back into place. The mesh is secured in place and the tools are then removed. Your incisions will be closed with stitches. A bandage will cover your incisions to keep them clean and dry. A bandage will also help prevent infection.

After your surgery:

You will be taken to a room to rest until you are fully awake. Caregivers will monitor you closely for any problems. Do not get out of bed until your caregiver says it is okay. When your caregiver sees that you are okay, you will be able to go home or be taken to your hospital room.


  • You cannot make it to your surgery.
  • You have a fever.
  • You get a cold or the flu.
  • You have questions or concerns about your surgery.

Seek Care Immediately if

  • You have an upset stomach or are vomiting.
  • Your hernia area suddenly becomes very painful.
  • Your lump increases in size, or you are not able to gently push it back into your abdomen.


  • You may have bruising, fluid buildup, swelling, or infection at your surgery site. A deep infection may also occur from the mesh patch used during surgery. You may have trouble emptying your bladder after surgery. You may have shoulder and chest pain from the gas used during your surgery. In some cases, an endoscopic TEP hernia repair may need to be changed into an open hernia repair surgery. An open surgery means that larger and deeper incisions will be made. These incisions will take longer to heal.
  • Your nerves, blood vessels, or abdominal organs may be injured during surgery. You may also have chronic pain or numbness in your groin area for months or years after your surgery. You may need to have another surgery if your condition returns or occurs in a different area. Without this surgery, your pain or discomfort may increase. Your soft tissues or bowels may become trapped in your abnormal opening. When tissues and organs are trapped, the tissue may die. This may become life-threatening.
