Two Cases of Rectal Dieulafoy's Lesion with Massive Hematochezia in Elderly Patients

ABSTRACT

Dieulafoy's lesion is rare cause of massive gastrointestinal bleeding. Dieulafoy's lesion is understood to represent a tiny submucosal defect with fibrinoid necrosis at its base, overlying a large, tortous, thick-walled artery in the muscularis mucosa. Although the original descriptions and early reports were of lesions in the proximal stomach, similar lesions have subsequently been reported in the esophagus, duodenum, jejunum, colon and rectum. Rectal Dieulafoy's lesion is rare but it is one of the causes of massive hematochezia. We report two cases of rectal Dieulafoy's lesion that was successfully treated with endoscopic hemostasis by clipping in the elderly patients.
