I had important surgery to remove appendix, may have Intestinal adhesion problem, need second opinion before surgery?

Hi, I am 35. 2 years back had undergone a big surgery to remove my appendix. It was big because they couldn’t diagnose the cause of the pain and the cut my stomach. Its a big horizontal cut starting from little above the navel point till the beginning point of pubic region. My problem is since that time im having a bloating stomach. I showed it to a Gastro Doc. He said could be Intestinal adhesion and may need to operate if it is painful or if it is obstructing the bowel. I dont have any pain. What could it be and how do i get rid of it? Please help.
