I'm betting you have a loop ileostomy - a form of temporary ileostomy. With this type of ileostomy you will have two openings - the main stoma, connected to your upper digestive tract, which expels stool and a smaller one called a mucous fistula which is connected to your rectum (you may not even be able to see it). Since both stomas are housed in the same bag it is possible for some stool from the bag to enter the mucous fistula and pass via your rectum and anus as 'normal' stool. It's nothing to be worried about but scary if you're not told it can happen.
Good luck :)
I have had an ileostomy for 32 years now due to UC.
