Endoscopic ultrasonography classification of gastric varices in patients with cirrhosis. Comparison with endoscopic findings.

Endoscopic ultrasonography was performed in 80 cirrhotic patients and 50 control subjects. The aim of the study was to describe and classify the vascular abnormalities of the gastric wall as observed on echoendoscopy in cirrhotic patients and to compare the data with endoscopy. The size of gastric varices was classified into 3 grades: grade 0 (none), grade 1 (small or non-confluent varices < 5 mm), grade 2 (large or confluent varices > or = 5 mm). The abnormalities of the gastric wall were classified into 3 grades: 0 (none), grade 1 (thickening and brilliance of the third hyperechogenic layer with or without fine internal anechogenic structures), grade 2 (visible vessels in the third layer which deform the entire wall, with penetrating varices). Endoscopy provides better visualization of esophageal varices than echoendoscopy but does not detect gastric varices and the first signs of portal hypertension as well. In conclusion echoendoscopy should be a routine examination for screening portal hypertension in cirrhotic patients and could be used in therapeutic follow-up.

[Reversal of portal blood flow in cirrhosis. Clinical, endoscopic and ultrasound endoscopic correlations in 72 patients].

From January to December 1991, the portal venous system was evaluated by Doppler ultrasonography in 72 patients with liver cirrhosis. The objectives of this study were to evaluate the prevalence of spontaneous reversal of blood flow in the portal vein and to assess the relationship between Doppler ultrasound investigation and clinical, biochemical, endoscopic (70 patients), and endosonographic (44 patients) features. Reversed flow was quite frequent (alternating: 17%, permanent: 22%) and its prevalence did not differ in relation to age, sex, serum gammaglobulin concentration and Child-Pugh class. In patients with reversed portal venous flow, the prevalence of hepatic encephalopathy was higher (39% vs 13.5%, P < 0.05), but the prevalence of esophageal or gastric varices was not related to that pattern. Endosonography detected gastric wall abnormalities in a higher proportion of patients with reversed portal flow than in patients without it (P < 0.05). This study suggests that reversal of flow in the portal vein could play a role in the development of the gastric wall abnormalities in liver cirrhosis, which are detected by endosonography but not by endoscopy.
