I did have SNS about a year and a half ago at Mayo Rochester through the colorectal surgery department. I was very happy with the surgeon that placed it and the care I received before and after. I had colonic inertia and had recently developed fecal incontinence without any warning occurring maybe once a week or less, but with no notice. I was offered the trial though CR Surgery which was done for constipation and fecal incontinence, It did help the fecal incontinencei buy not the colonic inertia. Because of the severe constipation, I have a loop ileostomy. I also had urinary retention which it helped completely, so we left the SNS in. I would definitely try it from my experience. Personally, I think I would prefer CR surgery to perform it (but I am a retired SIIC nurse).. . I'm not sure if GI does it at Mayo. I live in Florida and I still would still fly to Rochester! Ive been to JH, but prefer Mayo at least as far as clinics go,
