First, I am glad to be able to help you and I hope that your pain subsides soon.
I had deep infiltrating Endometriosis and it was in my rectum, sigmoid colon etc and I had an "Endo specialist" remove it all without damage. Yes there is a risk but that doctor by the sounds of it doesn't have the skill that an Endometriosis specialist would.
Please find someone else to do the surgery. You can read my profile as well as my journal about my journey with Stage IV Endometriosis.
PM me if you have any questions at all. I have lived with this disease for 23 yrs and I wasnt diagnosed until 17 yrs later after the symptoms began.
HI,
In cases where surgery cannot be done, medical management will prove useful. This can be with help of hormones like progesterone. Also GnRh analogues like lupride may help reduce the endometriosis. Symptomatic relief of pain should also be done. Consult a gynaecologist for an evaluation.
Hope this helps.
