Hi i'm almost two years post op open rny. Two months after my surgery I developed a bowel obstruction caused by adhesions and had another surgery to fix it, after that everything was fine. About three weeks ago I started having some pain after eating or drinking, so I went to my pcp and he ordered a ct scan of abdomen but he could not see anything wrong. Than the pain stopped. Three days ago I woke up at 4am because of the same type of pain, so I went to see my surgeon and I gave him the ct scan films, he showed it to the radiology technicians in his hospital. Yesterday he called me and said that the small intestine is thickened. I'm going to have an upper gi tomorrow. Can any one explain what that could mean please? Thank you
