The Role of Push Enteroscopy in Patients With Passing Melena With Nondiagnostic EGD.

All patients enrolled in this study underwent evaluation using push enteroscopy (PE)

After push enteroscopy (PE), all patients subsequently underwent a colonoscopy on the same day or the next day. However, if a culprit lesion was identified during PE and the patient was considered at risk for undergoing colonoscopy, the colonoscopy was not performed and was presumed to be negative.
