Acute variceal hemorrhage in patients with alcoholic cirrhosis and poor liver function is associated with a high mortality. A nonoperative treatment, endoscopic sclerotherapy, was employed in 22 patients with cirrhosis and poor liver function who had 24 episodes of acute variceal hemorrhage over a 20 month period. Portal hypertension was secondary to alcoholic cirrhosis in 21 patients and cystic fibrosis in 1 patient. Of the 24 patient admissions, 21 were of patients in Child's class C and 3 were class B. Endoscopic sclerotherapy was performed under endotracheal general anesthesia using a modified Negus rigid esophagoscope. The sclerosant (5 percent sodium morrhuate) was injected into all visible varices near the gastroesophageal junction using a MacBeth needle. Definitive control of variceal hemorrhage for the entire hospitalization was achieved in 19 of 24 admissions (79 percent). The in-hospital mortality for acute variceal bleeding was 29 percent; 81 percent of the patients were discharged after control of hemorrhage. There were two major and five minor complications related to sclerotherapy. Based on this preliminary experience it is concluded that injection sclerotherapy controls bleeding and reduces mortality associated with acute variceal hemorrhage in patients with poor liver function.
