Patients who have experienced multiple episodes of LGIB without a known source or diagnosis should undergo elective mesenteric angiography, upper and lower endoscopy, Meckel scanning, upper GI series with small bowel examination, and enteroclysis. Elective evaluation of the entire GI tract may identify uncommon lesions and undiagnosed arteriovenous malformations (AVMs).
