The medical treatment of congenital pyloric stenosis.

Even outside paediatric circles the clinical picture of congenital stenosis of the pylorus is nowadays well known, although Bloch as late as 1906 wrote that ' stenosis pylori congenita ' was not recognized by paediatricians until several years after Hirschsprung described it in 1887, and even then in 1906 it was little known to the medical profession in general. Since then the disease has been much described and discussed. That it is not an unusual malady appears from the fact that in the Children's Department of the Rigshospital alone more than 200 cases of it have been treated in the course of twenty-three years. The various authorities agree with regard to the clinical description, but there the unanimity ends. There are highly diverse opinions as to the pathogenesis, and equal disagreement as to the treatment. As regards the pathogenesis only some of the usual points of view which have come to the fore will be touched on here, without any definite conclusions.
