| | Pyloric Stenosis |
 | | Stenosis occurs due to an obstruction in the lumen of the pylorus, either in its walls or their contour, caused by a strange body, a pediculated vegetation or lesions in the walls, usually of cancerous origin, though the most frequent are those caused by duodenal, prepyloric, juxtapyloric, and duodenal pyloric ulcers. |
 | | Pyloric stenosis, due almost always to an ulcerous or neoplastic process of the duodenum, is the most frequent, and we shall talk about it. |
 | | Radiologically, gastric ptosis is differentiated from the dilation produced by stenosis because with ptosis the stomach adopts an almost spherical figure, and its vertical diameter is larger than the transverse one. |
