Changes in portal hypertensive gastropathy after endoscopic variceal sclerotherapy or ligation: an endoscopic observation.

To determine the effect of endoscopic variceal sclerotherapy or ligation on portal hypertensive gastropathy, 90 cirrhotic patients with esophageal variceal bleeding were randomized to receive sclerotherapy (n = 44) or ligation (n = 46). Follow-up endoscopic observations of the gastric mucosa were recorded at 3-month intervals after variceal eradication. Clinical characteristics in both groups were similar. Probability for a change in the severity of portal hypertensive gastropathy was not related to method of eradication. Most cases of portal hypertensive gastropathy that changed in severity returned to baseline status with time, but the return was faster after ligation than after sclerotherapy. According to the results of multivariate analyses, sclerosant volume was the only factor associated with a significant difference between the group with static gastropathy (n = 15) and that with dynamic change in gastropathy (n = 23) after sclerotherapy. No relevant factors were found in the patients receiving ligation. We conclude that changes in the severity of portal hypertensive gastropathy after endoscopic variceal sclerotherapy or ligation are reversible. Most cases of gastropathy return to baseline status sooner or later.
