Portal-hypertensive gastropathy develops less in patients with cirrhosis and fundal varices.

BACKGROUND/AIMS: The aim of this prospective study was to examine the association of portal-hypertensive gastropathy and fundal varices in patients with cirrhosis.

METHODS

We carried out an endoscopic observation in 476 patients with cirrhosis (study 1), including 62 patients undergoing endoscopic obliteration of esophageal varices (study 2). In study 1, patients were classified into five subgroups: no esophagofundal varices (n=119), small esophagofundal varices (n=127), dominant esophageal varices (n=177), dominant fundal varices (n=27), and large esophagofundal varices (n=26). The severity of liver dysfunction was assessed by Pugh-Child classification: class A (n=222), class B (n=200), and class C (n=54). In study 2, two groups, poorly developed fundal varices (n=50) and well developed fundal (n=12), were distinguished and the follow-up endoscopic examinations were performed on the basis of 3-month intervals for 2 years. In each study, the severity of portal-hypertensive gastropathy was scored: 0 (absent), 1 (mild), 2 (severe), and 3 (bleeding).

RESULTS

Study 1: One-way ANOVA showed that both variceal pattern and Pugh-Child class significantly influenced portal-hypertensive gastropathy score. However, two-way ANOVA indicated that variceal pattern was the only significant variable. Portal-hypertensive gastropathy score was significantly higher in patients with dominant esophageal varices than in either patients with no esophagofundal varices or patients with small esophagofundal varices. In contrast, portal-hypertensive gastropathy score in patients with dominant fundal varices was similar to that in patients with no esophagofundal varices and was significantly lower compared with that in patients with dominant esophageal varices. Furthermore, portal-hypertensive gastropathy score was significantly lower in patients with large esophagofundal varices than in patients with dominant esophageal varices. Study 2: After the obliteration of esophageal varices, portal-hypertensive gastropathy score in patients with poorly developed fundal varices became significantly higher at 3-, 6-, 9-months while it was not modified in patients with well developed fundal varices during the follow-up period. Furthermore, the integrated incremental change in portal-hypertensive gastropathy score during the first 1-year follow-up period was significantly lower in patients with well developed fundal varices than in patients with poorly developed fundal varices.

CONCLUSIONS

These results indicate that both spontaneous and obliteration-induced portal-hypertensive gastropathy lesions develop less in patients with cirrhosis and fundal varices.
