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.</p>
