I'm sorry you're going through this too! Just a word of warning/advice. A few years ago a laparoscopic surgeon assured me that he could remove my adhesions so that the SBO's would stop. I will try just about anything except for that Clear Passage thing (which sounds to me like a scam), so I went ahead with the surgery. It broke my heart when I had several SBO's after that!
So I would ask a LOT of questions–how likely would the colostomy bag be (that would be awful), and do they really think that they can remove ALL of the adhesions? The other thing to consider is that from what I understand surgery to remove scar tissue can sometimes cause MORE scar tissue, especially if they end up having to do open (instead of laparoscopic) surgery–and sometimes they don't know if they will have to do that until they've already "gone in."
I'm not saying that you shouldn't consider it, but ask a lot of specific questions about efficacy versus risk.
Good luck, and keep us posted!
