Hi, I'm new too with pan colitis. I was hospitalized for one month; I have been on Prednisone for since January 21st (down to 30 mg a day--I was on so long because I developed breathing problems). I am also on Asacol 800 mg three times a day, but I cut it down to 400 mg three times per day to see if my breathing problem gets better.
I have had the pink flakey fleshy thing you speak of. It's part of the disease and also occurred with me during my prep for my colonoscopy. I don't think it affected the procedure or the outcome. My doctor told me if anything was left in the colon, they just vacuum it up (gross). He diagnosed me with UC/PC--I didn't think I'd have this forever as I have MS too. Are you on a special diet? I notice if I go near anything containing dairy or fiber, I start to get blood in my stool. I'm sure everything will go well for you. God bless.
