The three nonsurgical modalities used to diagnose lower gastrointestinal bleeding (LGIB) are colonoscopy, radionuclide scans, and angiography. Apart from colonoscopy, endoscopic procedures, such as esophagogastroduodenoscopy (EGD), wireless capsule endoscopy (WCE), push enteroscopy, and double-balloon enteroscopy, are used depending on the clinical circumstance. The sequence of using various modalities depends on such factors as rate of bleeding, hemodynamic status of the patient, and inability to localize bleeding with the initial modality.
