Medically reviewed by Last updated on Dec 2, 2022.


What you need to know about pilonidal cyst excision:

A pilonidal cyst excision is the removal of a cyst on your lower back that has become infected or abscessed (collection of pus).

How to prepare for pilonidal cyst excision:

  • Your healthcare provider will tell you how to prepare for this procedure. You may be asked to not to eat or drink anything after midnight on the day of your procedure. Arrange to have someone drive you home after your procedure.
  • Tell your provider about all medicines you currently take. He or she will tell you if you need to stop any medicine for the procedure, and when to stop. He or she will tell you which medicines to take or not take on the day of your procedure.

What will happen during pilonidal cyst excision:

  • You may be given general anesthesia to keep you asleep and free from pain during surgery. You may instead be given local or spinal anesthesia to numb the area. With local or spinal anesthesia, you may still feel pressure or pushing but you should not feel pain.
  • You will be placed on your stomach. Your surgeon will make one or more incisions on your lower back on or around your cyst to remove it. Your surgeon may put dye in the incision to help the cyst show up clearly.
  • The incision may be closed with stitches or left open to heal. A bandage or wound vacuum will be placed over your incision to keep it clean and dry, and to prevent infection.

What to expect after pilonidal cyst excision:

  • You may have pain after surgery. Pain should get better within a few days.
  • A scar may develop as the incision heals. The scar may become large and raised.

Risks of pilonidal cyst excision:

You may bleed more than expected or get an infection. Your stitches may come apart. The cyst or abscess may develop again.

Seek care immediately if:

  • You have a fever.
  • You are bleeding from your surgery area.
  • You are having severe pain.
  • Your stitches come apart.
  • Your surgery area is red, hot, or draining pus.

Call your doctor if:

  • You have questions or concerns about your condition or care.


You may need any of the following:

  • Prescription pain medicine may be given. Ask your healthcare provider how to take this medicine safely. Some prescription pain medicines contain acetaminophen. Do not take other medicines that contain acetaminophen without talking to your healthcare provider. Too much acetaminophen may cause liver damage. Prescription pain medicine may cause constipation. Ask your healthcare provider how to prevent or treat constipation.
  • Antibiotics may be given to treat infection caused by bacteria.
  • Take your medicine as directed. Contact your healthcare provider if you think your medicine is not helping or if you have side effects. Tell your provider if you are allergic to any medicine. Keep a list of the medicines, vitamins, and herbs you take. Include the amounts, and when and why you take them. Bring the list or the pill bottles to follow-up visits. Carry your medicine list with you in case of an emergency.


  • Care for your surgery area as directed. Keep the area clean and dry. Your healthcare provider will give you instructions for changing your bandage. He or she will tell you when you can bathe or shower.
  • Do not sit for long periods of time. Limit activities that create tension in your lower back.
  • Shave hair from the area. Consider laser hair removal after you have healed.

Write down your questions so you remember to ask them during your visits.
