Repeated endoscopic sclerotherapy for active variceal bleeding

Abstract

Emergency endoscopic sclerotherapy (EEST) during continued moderate to severe bleeding was carried out using a flexible endoscope and absolute alcohol as a sclerosant in 38 patients with variceal bleeding. Portal hypertension was due to cirrhosis in 27, noncirrhotic portal fibrosis in eight, extrahepatic obstruction in two, and Budd-Chiari Syndrome in one patient. A technically adequate EEST could be carried out in 36 (95%) patients, with successful control of variceal bleeding in 35 (92%). Thirty-one episodes of rebleeding occurred in 12 (31.6%) patients. Twenty-nine (93.5%) of these episodes could be controlled with repeated EEST, giving an overall success of 87%. The new approach of repeating sclerotherapy on every rebleeding episode up to a maximum of three course within 24 hours, use of a wide bore injector, and certain other technical innovations were found safe and effective. The mean (+/- SD) amount of alcohol injected per patient was 9.23 +/- 3.3 ml and the mean (+/- SD) number of injections needed per patient were 6.0 +/- 3.07. Complications were minor, transient, and similar to conventional sclerotherapy. There were three deaths, two due to massive rebleeding and one due to hepatic encephalopathy. It can be concluded that EEST is technically feasible during active variceal bleeding and is an effective and relatively safe procedure. It can serve as the first line treatment in this group of patients.
