I am sorry you are facing another surgery! It is never pleasant to realize that the hysterectomy didn't solve all of our problems!
Because you are having an oophorectomy--removal of the ovaries--I have moved your thread here to our Separate Surgeries forum where you can meet up with other women who have needed surgery outside their hysterectomy! Unfortunately, there are several of us!
I had a lap a couple years ago to clean up more endo and remove some adhesions. I also had to have a bit of work done on my vaginal cuff--an adhesion was connecting it to my bowel! Ouch! I had my surgery done with an endometriosis specialist to maximize my results!
As far as no hormones for six months...well, might work, might not! There are actually studies showing that if there is any endo left, it can perk right up once estrogen is introduced, no matter how long you go without HRT. To complicate the picture, endometriosis itself can produce estrogen. So can our fat cells! And there are dietary ways to introduce estrogen into the body! So being 100% estrogen free to try to keep endo at bay is very difficult!
Some doctors recommend progesterone/progestin, Lupron, or an aromatase inhibitor following surgery to see if that will help eliminate any missed endo. Also, some doctors who do allow estrogen replacement for women with endometriosis recommend using progesterone or progestin along with the ERT to try to keep any endo at bay.
The key for treating endo is to have it skillfully removed by an expert surgeon! Is the oncologist going to be doing your surgery? I have heard of other women having success with a gynecological oncologist when they were unable to see an endo specialist!
If you have specific endo questions, feel free to post them in the
Endometriosis Support forum!
I wish you all the best for your upcoming surgery! I hope it is completely successful for you!
