My grandmother has an intestinal blockage and was constipated. She recently had a movement, but now after numerous X-rays and CT scans, the Dr at the hospital where she is at is saying she needs surgery, despite the fact that nothing shows up on the X-ray or CT scan. It does not seem rationale to perform surgery on an elderly woman for a blockage, when there is no proof of one in the performed tests. Can you please weigh-in? Thanks.
