We present two cases of bleeding colonic Dieulafoy in patients with chronic renal failure who were treated with mechanical methods . In the first case, an active arterial bleeding without mucosal defectwas local ized in the descending colon. In the second case, a protruding vessel with activ e bleeding was found in the transverse colon. The two patients were initially tr eated with epinephrine and hemostatic clips. In the second patient, an endoloop was attached to the base of the previously placed hemoclips because of rebleedin g. To our knowledge, this is the first case of combined endoscopic approach with hemostatic clips and endoloop to treat a colonic Dieulafoy lesion. Colonic Dieu lafoy lesions reported in the relevant literature and the hemostatic treatments used are reviewed.展开更多
