Diagnosis of Lesions on the Lesser Curvature below the Cardia by “Reverse U-turn Method” with the Fiberscope

Summary

The recent progress of stomach endoscopy has made it possible to make 100% precise diagnosis on lesions in the lower part of the stomach. However, those in its upper part, especially on the lesser curvature below the cardia, cannot be observed and photographed well, because they are always in the shadow of the fiberscope itself even if the U-turn method is employed.

For the purpose of getting a front view of the lesser curvature below the cardia, we have tried “Reverse U-turn Method”; that is, contrary to the conventional U-turn method in which the tip of the fiberscope is turned over with its tip pressed against the wall of the greater curvature, the tip is turned over on the wall of the lesser curvature.
