I don't know where you are located, but would suggest you look through the archives regarding surgeons who can do this exact same surgery WITHOUT opening you up (laparotomy). Oh my, that might be like Pandora's Box - you are proven to form adhesions (3 previous laps), and IF they open you may not have the outcome you would do it for.
Please try to think long and hard before you commit to ANYTHING, regardless of what you decide. Wishing you all the best, not only in your surgery, but recovering as well.
