Yes. There is a possible chance that it could be adhesions again. The only way to know for sure is by going in to look and see. There are no current medical tests to determine if it is adhesions. The only true way to find out is by going in with an adhesion specialist. You may want to try http://www.adlap.org to speak wih a specialist there who maybe able to help you further.
I will keep you and your son in my prayers always. Dee
