Is it normal to have light bleeding from the rectum after small bowel resection? It seems to be round the feces but not in it. There's no pain.

Maybe. Slight bleeding could be from hemorrhoids or other anal condition. Cirrhosis can cause abnormally enlarged veins to occur in the gastrointestinal tract that could bleed. Best not to wonder & best is to contact your own surgeon who performed the surgery to get proper information for your own specific situation & conditions.
