Ditto what ct barrister has said. I have ulcers in my distal pouch that also bleed. I take canasa as needed and cipro at minimal dose possible. I also have issues with bacterial overgrowth as my anastomoses is narrowed from scarring and repeat inflammation. I do not bleed when passing stools but if I insert a Canasa up above the anastomoses
I often see blood on the tissue after. I have had my pouch for almost four years and this is ongoing.
