I have had an Ileostomy for 7 years now and occasionally my stoma protracts outward and is swelled up. I have no idea what causes the spasm but I just wait and in 3 or 4 days it goes back to normal. I used to have a lot of problems with bag leakage but then discovered if I cut the hole bigger in the base plate the leakage past the adhesive piece was not a problem any more. Hope this helps.
