Laparoscopy surgery

So I just had endometriosis laparoscopy surgery. I've had all the symptoms of endometriosis. My doctor said she found two lesions they will be sending them off to see what it is. I guess I though you would be able to tell if its endometriosis and would look different. Has anyone else who had endometriosis been diagnosed through a leison? The wait tonget the results back are feeling like forever.
