Erosive Gastritis and Portal Hypertension

摘要

There is conflicting evidence concerning the effects of portal hypertension on the gastric mucosa. Thispaper summarises the histological and haemodynamic alterations which are present in both human andexperimental portal hypertension. Despite the fact that histological studies suggests that the gastricmucosa is an oedematous plethoric structure in portal hypertension, haemodynamic studies show thatgastric 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 presentin the gastric mucosa in portal hypertension.
