title: Unusual sites of upper gastrointestinal variceal bleeding.
abstract: When patients with portal hypertension bleed from varices, these are most commonly located in the esophagus and gastric fundus. However, varices can develop anywhere in the upper or lower gastrointestinal tract. Oftentimes if an active upper gastrointestinal bleeding site is not evident at the time of endoscopy, bleeding is attributed to any esophageal or gastric varices that are present. This supposition may not always be true as illustrated in the two patients presented here. Likewise, the absence of esophagogastric varices in a patient with portal hypertension does not preclude the presence of varices elsewhere. Endoscopic examination of the second and third portion of the duodenum can sometimes be helpful in accurately locating the bleeding site.
