Abstract
BACKGROUND/AIM
The relationships between the levels of portal hypertension and the morphologic alterations of gastric mucosa in patients with liver cirrhosis--generally described as portal hypertensive gastropathy--are poorly defined.
PATIENTS
In total, 62 patients with cirrhosis of different aetiologies, were examined by endoscopy and measurement of portal hypertension by hepatic venous pressure gradient.
RESULTS
Portal hypertensive gastropathy was observed in 49 cases; six patients showed gastric antral vascular ectasia always associated with gastric lesions described as severe portal hypertensive gastropathy with different localizations. Hepatic venous pressure gradient showed severe portal hypertension in 37 cases, and averaged 17.7 +/- 4.3 mmHg. It was much higher in patients with severe lesions (p=0.0004). Hepatic venous pressure gradient in patients with endoscopic signs of isolated antral gastropathy was lower (p=0.04) than in those with isolated lesions in body-fundus. No relationship was found between hepatic function, as assessed by the Child-Pugh score, and portal hypertensive gastropathy.
CONCLUSIONS
The present data suggest that the severity of portal hypertensive gastropathy is related to portal hypertension, but portal hypertension is not the sole determinant of the occurrence of endoscopic abnormalities of gastric mucosa. The derangement of liver function does not appear to play any role in the occurrence of portal hypertensive gastropathy.
