You did the right thing by getting a second opinion!
The Mirena Coil might buy you some time, especially if it was done in conjunction with a lap to clean up any endo. Keep in mind, the more skilled the surgeon is who cleans up the endometriosis, the better, with any surgery.
Have you ever consulted with an endometriosis specialist
? If not, I would suggest you do so. Those are the doctors who have the skills to offer us the most successful outcomes as they tend to have superior excision skills and recognize the various appearances and hiding places of endometriosis.
You could try the Mirena Coil alone for now if you are not ready for another surgery. If after a few months you do not have the symptom relief you are looking for, then you could consider a lap and the Mirena Coil.
It is important that you do realize a hysterectomy with/with a BSO is not a cure for endometriosis. If any endometriosis is missed, it has potential to grow and spread even without ovaries. For one, endometriosis can create its own supply of estrogen. The key is the removal of the actual endometriosis implants, not the reproductive organs. Additionally, surgical menopause can be quite difficult for many women and can open the door to other health issues. So you do want to carefully weigh your pros and cons before scheduling a BSO.
