There is only one certain way to diagnose Endometriosis and that is by a minor surgerical procedure called a laproscopy. During a laproscopy, the patient is put to sleep with anesthetic and their abdomen is distended with carbon dioxide gas to make the organs easier to see. While the patient is under anesthesia, a laproscope is inserted into a tiny incision in the abdomen and by moving it around, the surgeon can check the abdomincal organs to see if there are any endometrial implants.
