 Although small-intestinal vascular lesions can't be diagnosed by barium study, they were the bleeding source in a large percentage of patients with Mid-GI-bleeding. The progress of enteroscopy has been changing the diagnostic and therapeutic algorithm for these vascular lesions. There are 3 pathological conditions of vascular lesions. Angioectasia is characterized by venous/capillary lesions, Dieulafoy's lesion is characterized by arterial lesions, and AVM is a condition in which arteries and veins are directly connected without capillary beds. We classified vascular lesions with consideration of the presence or absence of pulsatility. The presence or absence of arterial components provides important information in understanding the pathological conditions and in selecting endoscopic treatment.
