Jejunal Dieulafoy's lesion: case report and literature review.

Dieulafoy's lesions are rare and usually present in the stomach. There are only 18 cases of jejunal Dieulafoy's lesion reported. It can present as a massive gastrointestinal bleed and a high grade of suspicion is necessary for a quick and effective approach. The authors present the case of a 14-year-old adolescent with a sudden onset of hematochezia and shock. The high and low endoscopies as well as the arteriography were all inconclusive. An exploratory laparotomy was undertaken in the first 24 h of hospital admission. A review of the small bowel by advancing soft bowel clamps in a sequential manner revealed a bleeding lesion in the jejunum. The histological exam showed a Dieulafoy's lesion.
