I had a procto-colectomy with a j-pouch due to UC not CI but contrary to Angel's post, this surgery has given me my life back. I have no diet restrictions and am very physically active. The best advice I can give you is to find a good colo-rectal surgeon and go for a consultation. My surgery was more complicated than a straight colectomy (my rectum was removed too, for CI you get to keep your rectum). The prep was the same as for a colonoscopy, no food for 12 hours and a bottle of mag citrate. Prep for CI might be more involved, I don't know. Surgery was 1.5 hours (I had one of the top surgeon's in the country) and I was in the hospital for 7 days. I was only on morphine for 12 hours, vicodin after that. I went back to work 3 weeks after surgery.
I do not have diarrhea, I have formed stools and poop normally, just more frequently.
I am 7 weeks post op for laparascopic colectomy with ileo rectal anastomosis. I decided to go to the Cleveland Clinic even though I live in NY due to their reputation. I wanted a surgeon who did this all the time and not someone who did hernias one day and gall bladder the next plus the laparascopic procedure is a bit less invasive...
My surgical prep was miralax and ducalax pills...I only ate full liquids for 3 days preop so the prep was not so bad. Preop I had an injection of heparin and anti embolic compression boots to prevent blood clots. I also was given cipro and flagyl intraop and post op for a few days. My surgery took approximately 4 1/2 hours due to adhesions from previous multiple gyn surgeries and the fact that the intestine was extremely redundant. I had a pain pump which I used when getting in and out of bed and whenever necessary. I walked the next morning and took a shower, although sitting in a chair and with help on the 2nd day. They slowly advanced my diet. I pooed on the 5th day and was discharged on the 6th. I was given vicodan for pain and we returned to NY on the 10th day.
I have had no major complications except I go to bathroom about 15-20/ day and am now taking imodium to try to get this under control...butt is a bit sore..I am retired so bathroom issue not a big problem...The surgeon told me that it may take anywhere from 6 months to a year for everything to calm down...I eat everything without problem...and to tell you the truth I'd rather be like this then to endure the pain I was in before..
I hope this helps with your questions
