With Crohns an internal pouch isn't possible (ie the j pouch or kock's pouch) unfortunately because the Crohns can come and infect the internal pouch necessitating further surgery and loss of sorely needed bowel :( Having said that, there are some surgeons who say you can have a j pouch or kock's pouch if you have crohns that has been contained to the large bowel only for at least 5 years cos the chances of it striking anywhere else are remote.
Allie, I'm presuming you have a loop ileostomy (ie two
openings - the main stoma and a smaller one called a mucous fistula (connected to the lower bowel and rectum) which might be a little hard to see for some people). When they reconnect you they'll just join the two bits back together again.
If, instead, you have a hartmann's pouch, then you'll have a stoma but the other end (connected to your rectum) will be closed off and floating around inside you. Once again, the surgeon will just reconnect the two bits together for you.
I have had an ileostomy for 30 years now due to UC.
I'm not a complete idiot - some parts of me are missing!
