Sphincter issues, rectal tenesmus, radiation enteritis, hernias

I have low functioning anal sphincter, rectal tenesmus, radiation enteritis, tortuous colon and 5 hernias in small bowel area. this all follows cysectomy with a section of my colon used for uteral conduit plus aggressive radiation and chemo. My GI doctor says there is nothing he can do since I am loaded with scar tissue after 5 surgeries. I am miserable every waking minute of every day. Pain, tension, uncontrollable bowels and a fight to overcome depression. I am going crazy!!!!
