Abstract
The prevalence of gastric ulcer and its relationship to the severity of cirrhosis and degree of portal hypertension was evaluated in 245 cirrhotic patients, and compared with 245 age‐ and sex‐matched healthy subjects. Portal and systemic haemodynamic studies were performed in cirrhotic patients. The prevalence of gastric ulcer in cirrhotic patients was 20.8%, which was significantly higher than the 4.0% found in healthy controls. Using a multivariate logistic regression model, the hepatic venous pressure gradient was found to be the only predictor of the prevalence of gastric ulcer in cirrhotic patients to present with gastric ulcer. The hepatic venous pressure gradient was significantly higher in cirrhotic patients with gastric ulcer than in those without (17.3 ± 4.4 vs 15.5 ± 5.0 mmHg, P= 0.01). Other variables, including sex, smoking, cardiac output and severity or aetiology of cirrhosis did not show significant differences between the two patient groups. The prevalence of gastric ulcer in cirrhotic patients whose hepatic venous pressure gradient was below 12 mmHg (4.5%) was similar to that observed in the healthy controls (4.0%). However, when the hepatic venous pressure gradient was > 12 mmHg, the prevalence of gastric ulcer (24.4%) was significantly higher than that in control subjects. However, the incidence of gastric ulcer was not related to the degree of portal hypertension. In conclusion, the prevalence of gastric ulcer in cirrhotic patients was found to be significantly higher than in the age‐ and sex‐matched healthy subjects. Portal hypertension with a hepatic venous pressure gradient > 12 mmHg may be an important factor contributing to the increased prevalence of gastric ulcer observed in patients with liver cirrhosis.
