Abstract

Using endoscopic ultrasonography (EUS) a large part of the portal venous system can be visualized. In 40 patients with portal hypertension (PH) and in 48 control subjects EUS displayed the azygos, splenic, mesenteric and portal veins in both groups. However, esophageal and gastric varices, peri- esophageal and peri-gastric collateral veins and submucosal gastric venules were displayed only in patients with PH. EUS was inferior to endoscopy for detecting and grading esophageal varices (p < 0.0005), but superior in the detection of varices in the fundus of the stomach (p < 0.0005). EUS cannot be considered a reliable method for the study of esophageal varices: it has an overall sensitivity of 50 %, does not permit flow measurements, and does not provide information that could be used to estimate the risk of bleeding. EUS has been demonstrated to be superior to endoscopy in the diagnosis of gastric varices. This finding is extremely important for the optimal selection of treatment of patients with portal hypertension. EUS can detect portal hypertensive gastropathy; thus inflammatory gastritis can be more easily distinguished from congestive gastropathy and therapeutic decisions are strongly influenced.
