Of course since endometriosis does not come from the lining of the uterus, this is not a valid approach for endometriosis alone. Over the next few years physicians everywhere began to try the methods and to tell patients that if they didn't get a good outcome then the theory was flawed or it was in the patient's head. In fact it takes time to learn to recognize, locate and excise endometriosis. But physicians worldwide have begun to embrace the techniques as they use simple inexpensive tools. Laser surgery burst on the scene in the mid-late 1980's but it was doomed as a treatment for endometriosis, as the laser has limited ability to destroy the glands and stroma of endometriosis.
Cautery too does little to destroy complex disease.
The standard of care for women with endometriosis in England has become excision for improved pain and pregnancy outcomes. All endometriosis should be excised, and in doing so often the path reports will come back noting that the glands and stroma that diagnose the disease are present by are over lain by a layer of carbon. Current thinking is that the carbon is deposited by attempts to destroy endometriosis by laser and cautery. It is known that complex disease is unlikely to be destroyed by burning it up. Many physicians are intimidated by severe or obscure disease.
