[Differentiation of tumors of the anterior wall of the stomach from neighboring intact areas by the method of multichannel gastrography].
By means of simultaneous multichannel recording of stomach biopotentials from the surface of the anterial abdominal wall, an active electrode being situated above tumor, we are able to recognize the decreased electric activity of the anterior gastric wall area, involved by cancer process. Multichannel electrogastrography from the body surface makes it possible to determine the boundary between the tumor and adjacent intact areas of the anterior gastric wall clearly enough.
