Whatever the cause, the stomach will eventuallybecome thinned and distended. If it contains comfortably more than40 ounces of water, it may be regarded as a dilated stomach. Pyloric obstruction of infancy is congenital or is acquired Fig. 71.—Operation of Roux completed (schematic). The symptoms of pyloric obstruction are properly those of gastricdilatation. An uncomplicated obstruction rarely gives rise to symp-toms. Obstruction with dilatation quickly becomes associated withgastric stasis—that is to say, ingested food remains in the stomachlonger than normal. If one removes with the stomach-tube the stomach-contents eight hours after the patient has taken a full meal, one shouldfind no trace of food if the stomach be normal. Food found aftereight hours signifies delayed motility or stasis, and the symptoms aredue to this stasis. The picture is a complicated and distressing patient becomes emaciated, is troubled with pain coming^ onthree or four hours after eating, has more or less vomiting, the vomitusvarying in amount according to its frequency, and at times—perhapsonce in three or four days or perhaps very rarely—he vomits enormous 140 THE ABDOMEN quantities of food.
