JEJUNAL VARICES AS A CAUSE OF MASSIVE GASTROINTESTINAL-BLEEDING

Jejunal varices are not a common manifestation of portal hypertension. This report describes a 46-yr-old man with recurrent massive gastrointestinal bleeding from jejunal varices arising in an area of adhesions between the intestine and the omentum. The bleeding site was identified by exploratory laparotomy. Medical therapy, including vasopressin infusion via the superior mesenteric artery, was of limited success for controlling acute variceal bleeding. However, jejunal resection and anastomosis resulted in complete resolution of the bleeding, and the patient has experienced no recurrent bleeding over a 3-yr follow-up period. A review of the literature shows that this syndrome is characterized by portal hypertension, generally due to liver cirrhosis; frequently, there is a history of abdominal surgery, and the syndrome presents with hematochezia but without hematemesis. Accurate preoperative diagnosis is often difficult. We propose that bleeding from jejunal varices, though uncommon, should be considered under such clinical conditions.
