Hi Marijo,
I'm curious to know what they tried the sacral nerve stimulation for? I recently had an Interstim placed mainly becasue of overactive bladder from MS but they were hopeful it would stimulate my lower bowels. So far it hasn't helped with the constipation issues and I too may be facing colectomy.
I am seeing my gyn about having my rectocele repaired next week. I posted on the total colectomy thread yesterday. How did you do from that part of your surgery?
Take care, I hope whatever decision you make is the best one for you!
