Abstract |
Portal hypertensive gastropathy (PHG) is a complication of cirrhotic or noncirrhotic portal hypertension. PHG is very important in the clinic because it can cause acute or even massive blood loss, and its treatment efficacy and prognosis are poor. Currently, the incidence of PHG in patients with cirrhosis is 20–80%, but its pathogenesis is complicated and poorly understood. Studies have shown that portal hypertension can cause changes in gastric mucosal microcirculation hemodynamics, leading to changes in gastric mucosal histology and function and thereby weakening the mucosal defense barrier. However, no specific drug treatment plans are currently available. This article reviews the current literature to further our understanding of the mechanism underlying PHG and the relationship between PHG and the posterior mucosal defense barrier and to explore new therapeutic targets.

The pathogenesis of portal hypertensive gastropathy.
Highlights |
• | Endothelial cell injury is the initiating factor in portal hypertensive gastropathy. |
• | Endothelial cell molecules cause dynamic changes in microcirculation perfusion. |
• | There is an interaction between endothelial cell damage and tissue damage. |
• | Anti-oxidation and anti-apoptosis can treat portal hypertensive gastropathy. |
• | Explain the possible molecular mechanism of portal hypertensive gastropathy. |
