Hey there! Depending on your reasons for the surgery, there shouldnt be a reason to have to jump straight into an ostomy if you just have constipation.
Check out total colectomy parts 1-7. I had the surgery in July of this year and I am doing great. Full colectomy with a ileorectal anastomosis.
If I can help in any way, let me know... I remeber the feelings you are going through!
