As has been suggested by many workers, in cases of high intestinal obstruction there are two fairly well defined groups of factors that probably operate in the pathogenesis of the untoward symptoms that develop.

In an analysis of some of the factors concerned in intestinal obstruction, Haden and Orr,1 in 1923, produced various types of experimental obstruction of the cardia and esophagus and reported that severe toxemia with rapid death resulted. They ascribed the symptoms and death to the same causes that were thought by them
