The pyloric antrum or pyloric canal to the right The pyloric antrum is 2.5 cm and terminates in pyloric orifice into duodenum.   What happens to the normal anatomical structural in CHPS? In infants with IHPS, the pyloric ring is no longer identifiable as a clearly definable separation between the normally distensible pyloric antrum and the duodenal cap. Instead, a channel of variable length (1.5–2.0 cm) corresponding to the pyloric canal separates the normally distensible portion of the antrum from the duodenal cap. ·          Infantile hypertrophic pyloric stenosis  was first fully described by  Harald Hirschsprung  in 1888. ·          IHPS VS CHPS - ?????
