. The diseases of children : medical and surgical. is a congeni-tal stenosis of the pylorus with a secondary dilatation and hypertrophy of thewalls of the stomach. We have seen several such cases. The infant, whichis born healthy, begins to vomit at about the end of the first week ; the vomit-ing continues, large quantities are pumped up till the stomach is empty.The vomiting then ceases for perhaps 12 or 24 hours, and the vomitingcomes on again. No bile is vomited, the stools are small and constipated.Wasting quickly takes place, and death from exhaustion occurs in 6 or 8weeks. Incases where the stenosis is slight, the symptoms are less marked, and life may be prolonged for 6 months or more. But little can be done inthe way of treatment; at the post-?noriem the pylorus is found thickened, forming a tumour, which has in some cases been felt during life, the thick-ening being due to hypertrophy of the muscular layer, the mucous coat isalso thickened. The pyloric channel is narrow, and the walls of the stomachhypertrophied. (See fig. 15.). Fig. 16.—Hour-glass constriction of ston:iach, from an infant of five months. Themuscular walls of the narrowed part were much thicker than the walls of the rest ofthe stomach. (Natural size.) Malformations of the Stomach.—These are certainly uncommon, buta slight degeee of hour-glass constriction which had been unsuspected duringlife may at times be found at post-mortems. In a case of our own in whichwe made the section, but did not see the infant during life, there was a well-marked contraction in the central portion of the stomach. (See fig. 16.)There was a history of constant vomiting during life. In such a case it isvery possible that there is no real malformation ; but it is difhcult to saywhether the narrowing is due simply to a spasmodic contraction of the normalmuscular coat at this spot, or whether there was a true hypertrophy. Carcinoma of the Stomach.—New growths in the alimentary canal areexceedingly rare in early l
