I guess there is always the risk that any abdominal surgery will simply cause more adhesions to form. My surgeon reminded me of this prior to my lysis however I wanted to at least give it a try. Surgery also brings with it other potentials for complications (which I am sure you are well aware). Bowel perforation, infection, sepsis, wound complications etc. Not a decision to be taken lightly. You are in the drivers seat here however and listen to the opinions carefully, weigh your options well and go with what will make you most satisfied.
Good luck, Michelle
