Background: Endoscopic ultrasonography (EUS) has been suggested to inv
estigate portal hypertension (PHT). We compared EUS and endoscopy in t
he exploration of PHT in cirrhosis. Methods: In 58 patients with cirrh
osis and 16 controls, the presence of esophageal varices and gastric v
arices was recorded by both endoscopy and EUS, peridigestive varices a
nd perforating veins by EUS. Relationships of patterns with each other
and with clinical and biologic data were evaluated. Results: In patie
nts with cirrhosis: esophageal varices were found by endoscopy and EUS
in 88% and 55% of cirrhotic cases (p < 0.01), and gastric varices in
17% and 41%, respectively (p < 0.01). Perforating veins, below the gas
troesophageal junction, were diagnosed by EUS in 40% of cases and neve
r in controls. A significant relationship was found between perforatin
g veins and the following patterns: peri-digestive varices, gastric va
rices at EUS, and esophageal varices at endoscopy. In patients with an
d without cirrhosis: after multivariate analysis, only esophageal vari
ces at endoscopy were independently related to cirrhosis. However, in
Child-Pugh class A patients, both esophageal varices and perforating v
eins were independently related to cirrhosis (diagnostic accuracy, 92%
). Conclusions: EUS is of limited value in the diagnosis of cirrhosis
because it gives little additional information to upper gastrointestin
al endoscopy. The relationships between perforating veins, varices, an
d peridigestive varices support the hypothesis that perforating veins
are important in the pathogenesis of esophageal and gastric varices.
