Hi, I had a 7 hour op to excise endo and a total hysterectomy for Adenomyosis all done laparoscopically. My ovary was stuck to my bowel also and had to be unstuck. A skilled endo surgeon is usually able to do this without resorting to laparotomy or to removing organs.
Do you live in the UK and if so are you having surgery at a BSGE accredited endo centre where they have skilled endo surgeons plus the use of colorectal surgeons, urologists and pain management specialists if necessary? If you are in the UK and you are not under the care of an accredited centre it may be prudent to hold fire on yet another op and request a referral as is your right under NHS choices and NICE guidelines to such a centre. A list of accredited centres can be found at the following website: bsge.org.uk.
Please be aware that even if your hospital is named as an accredited centre you need to check that you are seeing the named endo specialist on the list and not just the general gynaecologist at the hospital.
Look for a centre that is skilled in excision surgery (ie cutting out the endo), not one that uses ablation to remove the endo as this proves less effective particularly in deeper infiltrating endo. Burning endo removes the top of endo rather than removing it from the root meaning much like a weed it's more likely to grow back resulting in the need for yet more surgery.
With each surgery an endo sufferer runs the risk of further adhesions and scar tissue forming which can in itself cause pain and other issues so it's important to try to limit the number of surgeries required. Excision surgery offers the best chance of this with a skilled surgeon reducing the risk of reoccurrence in up to 50-60% of cases. This is why excision surgery is considered the gold standard in the treatment of endo.
Sadly not even all BSGE accredited endo centres are equal, some are better than others so it pays to ask around and travel further afield if necessary to find the right surgeon for you. Don't be put off travelling distances - my surgery took almost 7 hours and my journey home was 2.5 hours. I was worried it would be awful but it really wasn't that bad.
Whilst you cannot ask on this forum for specifics at to which centres are the better ones you can on EndoMetroplolis on Facebook so it may be worth going on this if you haven't already.
I hope this helps and I wish you all the best, Jo x
