The Dieulafoy lesion is a rare cause of severe gastrointestinal hemorrhage. The lesion is usually located in the stomach, although it may occur anywhere in the gastrointestinal tract. We describe four patients with extragastric Dieulafoy's disease, in the duodenum (one), the proximal jejunum (two), and the left hemicolon (one). Diagnosis was made by endoscopy in all four and confirmed by histology in three. The pathology of the Dieulafoy lesion is essentially the same throughout the gastrointestinal tract. Endoscopic treatment by sclerotherapy combined with electrocoagulation was successful in the duodenal and colonic Dieulafoy lesions, but not in the jejunal lesions.
Dieulafoy病变是严重胃肠道出血的罕见病因。该病变通常位于胃部，不过也可能出现在胃肠道的任何部位。我们描述了4例胃外Dieulafoy病患者，病变分别位于十二指肠（1例）、空肠近端（2例）和左半结肠（1例）。4例均通过内镜检查确诊，3例经组织学检查证实。Dieulafoy病变在整个胃肠道的病理本质相同。硬化疗法联合电凝的内镜治疗对十二指肠和结肠Dieulafoy病变有效，但对空肠病变无效。
