Abstract
Two rare cases with Dieulafoy-like ulcer bleeding of the colon and rectum are reported. The patients have been suffering from chronic renal failure (CRF) on long-term hemodialysis (HD), and they were brought to Saiseikai Yahata General Hospital with anal bleeding. In both patients, colonoscopy was performed, showing arterial bleeding from a protuberant vessel on the mucosa of the rectum in Case 1 and gradual arterial bleeding from the protuberant vessel on the ascending colon in Case 2. For both cases, endoscopic clipping treatment was done for hemostasis and was successful.
