Rectal Dieulafoy's lesion is an unusual cause of abrupt and massive lower gastrointestinal hemorrhage. It is characterized histologically by a caliber-persistent submucosal artery that protrudes through a minute mucosal defect. Various theories and risk factors have been proposed to explain the occurrence of bleeding but none is completely satisfying. We present two cases of rectal Dieulafoy's lesion which were treated efficaciously by a simple injection of a sclerosing agent in the first case and by a combination of epinephrine injection and thermal probe coagulation in the second leading to a complete and rapid disappearance of the abnormal vessel.
直肠杜氏病损是下消化道突然大量出血的一种罕见病因。其组织学特征为一条口径不变的黏膜下动脉通过微小的黏膜缺损处突出。为解释出血的发生，人们提出了各种理论和危险因素，但均不尽人意。我们报告两例直肠杜氏病损，第一例通过简单注射硬化剂有效治疗，第二例通过肾上腺素注射和热探头凝血联合治疗，异常血管完全迅速消失。
