ENDOSCOPIC EVALUATION OF INTRAVARICEAL INJECTION IN ENDOSCOPIC INJECTION SCLEROTHERAPY FOR ESOPHAGEAL VARICES

Abstract

To clarify endoscopic findings of genuine intravariceal injection, 207 injection sites of 26 patients have been studied in accordance with venographic findings. On endoscopic examination to judge genuine intravariceal injection the following requirements must be filled, 1) to observe backflow of blood into an injection needle and 2) no change in size of varices after injection. These critereia for genuine intravariceal injection can be considered to be useful to decide an appropriate dose of injecting sclerosant, to evaluate effectiveness of sclerotherapy and to prevent many complications. Based on this criteria overall rate of accurate intravariceal injection reaches 43% in our series.
