Illeostomy?

I am 7 months in on my T10-L5 Complete SCI. I am only having a bowel movement once or twice a week. I constantly feel bloated or just feel like complete s***. I also have complications with my Foley Catheter that is soon to be changed to a Super Pubic. I have found myself having to go to the ER due to the Foley coming out of me but as soon as it does, it seems I can have a bowel movement.

A nurse told me at Banner UFC in Phoenix to have a Illeostomy Bag placed to get out of my briefs and become more independent..

Does anyone have any knowledge of having an illeostomy? What is the difference in the illeostomy and the colostomy? Which is the better decision? I have a gastro appointment in about a week from today and would like some feedback in order to make a decision to request the surgery the day I go. Thank you for reading.
