Endoscopic sclerotherapy for esophago-gastric varices: a critical reappraisal.
Amongst the many non-surgical techniques for the treatment of variceal bleeding, endoscopic sclerotherapy (EST) has shown great promise. EST can successfully obliterate esophageal varices and prevent variceal rebleeding. It is also very effective in the control of active bleeding from esophageal varices. The technique of EST is simple and can be carried out with a conventional, forward viewing, flexible endoscope and a teflon injector. Weekly intravariceal injections of an aqueous sclerosant are preferable. Though complications of EST in experienced hands are low, prophylactic EST at present should be advocated only to patients at high risk of bleeding. While controversy exists, most reports indicate that EST improves survival of patients with portal hypertension who have bled from esophageal varices. With regular follow-up endoscopies, recurrence of varices and bleeding from them can be substantially reduced. Sclerotherapy may successfully obliterate gastric varices in some patients either following EST for esophageal varices or by direct gastric variceal injections. For the long-term management of portal hypertension, combination of pharmacotherapy before as well as after eradication of esophageal varices, needs proper evaluation.
