A small penetratingcurvature with barium food in .situ and gas bubble shown in upper part. The peristalticulcer on lesser marks the seat of an ulcer on the lesser curvature, which by cicatrisation hasled to organic contraction of the stomach. This condition has to be dis-tinguished from spasmodic hour-glass contraction, and from that caused bynew growth of the body of the stomach.
