Effects of Somatostatin on Post-endoscopic Portal Hemodynamic in Cirrhotic Patients With Esophageal Gastric Varices

Investigator Sponsored Study of Effects of Somatostatin on Post-endoscopic Portal Hemodynamic in Cirrhotic Patients With Esophageal Gastric Varices

The main complications of cirrhosis are ascites, esophageal varices and hepatic encephalopathy. About 30% to 70% patients with cirrhosis occur esophageal varices, and the most common complication is ascites. Somatostatin is used to treat esophageal for a long time, otherwise it could aslo prevent ascites. In the study, the investigators explore the effects of somatostatin on post-endoscopic portal hemodynamic in cirrhotic patients with esophageal gastric varices.

126 patients will be enrolled in the study, 63 subjects will be randomized into the group A and the other will be into the group B.

Group A: endoscopic therapy and somatostatin treatment. Group B: endoscopic therapy.
