hello. My mother has a hard stool high up in her colon that will not budge. 1 week in the hospital nearly killed her and 3 xrays later shows no change. No obstruction; full digestive tract and no change. What are the recourses for an 87 year old Alzheimer's patient? Oils, fiber, enemas, lactulose, stool softeners, water, suppositories have not worked.
