Detailed explanation-1: -A lower GI series is a procedure in which a doctor uses x-rays and a chalky liquid called barium to view your large intestine. The barium will make your large intestine more visible on an x-ray.
Detailed explanation-2: -Approximately, 80% to 85% of lower GI bleeds originate distal to the ileocaecal valve, with only 0.7% to 9% originating from the small intestine. The remaining cases usually begin in the upper GI tract. These patients usually present with brisk bleeding, melena, or bright red blood per rectum.
Detailed explanation-3: -Lower GI endoscopy lets your healthcare provider view your lower gastrointestinal (GI) tract. Your entire colon and rectum can be examined (colonoscopy). Or just the rectum and sigmoid colon can be examined (sigmoidoscopy).
