Another word for those "scars" is also known as adhesions which form due to many causes but if there are a few it can cause major blockage, they can be removed but there is a chance of creating more adhesions, which can cause even more issues. Pretty much a no win, they aren't really scars since they tend to stretch out like spider webs and connect to other internal organs, my grandmother actually suffered from the same and the had to take a chunk of her intestines out to fix it. One of the girls who was with me had a similar issue and was advised of the possible complications.
