Endometriosis surgery is required when medical treatment fails to release women from pain. However, complete surgery does not work every time to improve patients' symptoms. Algological care is one of the options to treat the pain before surgery and their related complications (neuropathy, sensitization, and catastrophism) that could be associated to nociceptive pain.

But not all patients could benefit from this pathway and no screening strategy does exist to detect these complications that could be treated prior to endometriosis surgery
