There is conflicting evidence concerning the effects of portal hypertension on the gastric mucosa. This paper summarises the histological and haemodynamic alterations which are present in both human and experimental portal hypertension. Despite the fact that histological studies suggests that the gastric mucosa is an oedematous plethoric structure in portal hypertension, haemodynamic studies show that gastric mucosal blood glow is at least maintained if not increased in portal hypertension. The term "active" rather than "passive" congestion is a more appropriate description of the basic change present in the gastric mucosa in portal hypertension.
关于门静脉高压对胃黏膜的影响，存在相互矛盾的证据。本文总结了人类和实验性门静脉高压中存在的组织学和血流动力学改变。尽管组织学研究表明门静脉高压时胃黏膜是一种水肿、充血的结构，但血流动力学研究显示，门静脉高压时胃黏膜血流即使没有增加至少也能维持。用“主动性”而非“被动性”充血来描述门静脉高压时胃黏膜的基本变化更为恰当。
