    Abstract:
    Thirty-seven patients with postnecrotic cirrhosis of the liver and 13 patients with primary hepatoma were proven to have repeated bleeding from ruptured esophageal varices. Clinically controlled trials were performed by assigning patients to either sclerotherapy or control arms (25 patients each). Combined intra-variceal and para-variceal injection before an upper endoscopic examination was performed in the sclerotherapy group. In all 25 sclerotherapy cases (100%) hemostasis was successful, which was a statistically significant success rate compared to the control group (52.0%) (p less than 0.01). In the sclerotherapy group 20% (5/25 cases) developed rebleeding, which was less than the 48.0% (7 cases of continuous bleeding and 5 cases of rebleeding) of the control group (p less than 0.05). Four cases (16.0%) in the sclerotherapy group died of erosive gastritis with massive bleeding, compared to 8 fatalities (32.0%) in the control group, because of uncontrolled esophageal variceal bleeding. Endoscopic sclerotherapy is a very effective method for arresting bleeding esophageal varices, and for decreasing the rebleeding rate.
