Endometriosis resection

What is endometriosis resection?

  • This entails keyhole surgery (5-10mm incision at the bellybutton, and 2-3 other 5mm incisions).
  • A camera is placed through the bellybutton to view the pelvis.
  • A device is placed on the cervix to manipulate the uterus.
  • The abdomen and pelvis is carefully explored, and abnormal tissue removed (excised).
  • Cysts (endometrioma) may be removed from the ovaries.

When is endometriosis resection performed?

When a patient has symptoms that may be consistent with endometriosis. This may be a first procedure or a secondary procedure if symptoms recur.

How is it the procedure performed?

Location: at Wakefield Specialist Centre

Anaesthetic: the procedure is performed under general anaesthetic, meaning the patient is asleep.

Duration of the operation: this depends on the extent of disease. Mild to moderate causes may take 45 to 90 minutes. Severe cases may take 2-4 hours.

What should I expect after endometriosis resection?

When you wake up: you will have an IV line in the arm or hand. A bladder catheter may also be present. The anaesthetist will have a management plan in place for pain to ensure you are comfortable.

Nights in hospital: most cases require a single night in hospital. Some patients will go home the same day (if mild disease is found).

Time off work: 1-2 weeks, depending on the extent of surgery required.

When back to normal functioning: exercise when you feel able, generally 1-2 weeks. You can have sex again when you feel able to, generally 1-2 weeks.


  • This will occur 3-6 weeks after the initial operation.
  • If any issues occur when discharged home, patients can contact the Wakefield Specialist centre directly.
  • Dr McDowell and Dr Bedford will be on call to assist when necessary.
