Hi. Thanks for your query. Noted the history and understood your concerns. your history of white mucus in stool, small pieces looking like raw red meat and flesh, but no blood in stool although there is pinkish liquid on toilet paper indicates one of the following: Intususception wherein the intestines travels through intestine and causes obstruction to the blood vessels causing such a problem. Since this may be a large bowel into large bowel, there is not much of a mechanical obstruction. Severe colitis can mimic the same. I would advise you hte following: Send the stool and blood for tests. Colonoscopy. Barium enema can be diagnostic as well as therapeutic . X-ray of the abdomen in standing position. Reduction of the bowel if intususception. If required resection anastomosis may be required. If there is colitis then the treatment is medical under the guidance of a Gastroenterologist.
