SUCCESSFUL ENDOSCOPIC HEMOSTASIS OF RECTAL DIEULAFOY's ULCER BY CLIPPING: AGING MAY BE A FACTOR

Abstract

Dieulafoy's ulcer is a rare form of gastrointestinal bleeding. 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. A 55‐year‐old man was admitted to hospital for a sudden acute headache. On admission he was conscious, and had severe occipitalgia due to a subarachnoid hemorrhage demonstrated on computed tomography. On the fifteenth hospitalization day, he passed fresh blood together with stool, followed by several further episodes of massive hematochezia. Although no lesion was found by gastroduodenoscopy, colonoscopy revealed fresh blood and clots in the rectum. No obvious source of hemorrhage could be identified until careful irrigation revealed pulsatile bleeding from a protuberant vessel (2 mm in size) in the rectum 5 cm from the anal verge. The patient underwent an endoscopic hemostasis in which the pulsatile vessel was easily sutured with seven clips. The patient did not have another episode of bleeding. The finding of Dieulafoy's ulcer in the elderly‐patient group suggests that sclerotic changes to the artery may be associated with this type of rectal ulcer.
