Thanks you, but my problem is not the stoma being too small, it is fine. My problem is that the actual opening to my pouch that the catheter goes through after getting past the valve was too small. That is why I could not intubate for four months and I had to have a tube in all the time. For me, they finally dialated the opening and it works fine for now, they just do not know for how long before it gets too small again.
