title: Detection of portal hypertension and esophageal varices by means of endoscopic ultrasonography.
abstract: Endoscopic ultrasonography (EUT) enables not only the visualization of the portal system and of the esophageal varices, as obtained by transabdominal ultrasonography and fiberoptic endoscopy, but also the visualization of intramural and periesophageal collateral veins. Fifteen cirrhotic patients were examined by EUT without complications. When present, esophageal or gastric varices were always detected. In all cases enlarged extrinsic periesophageal veins were visualized, and in 14 of 15 their caliber was correlated with the size of esophageal varices. In three patients examined after sclerotherapy the submucosal veins had disappeared, but extrinsic collateral vessels were patent. EUT will probably become a fundamental technique in the study of portal hypertension and esophageal varices, before and after therapy.
