(From the Pathological Museum, Columbia University, New York.) Symptoms.—The symptoms of pyloric stenosis may be divided intothose: 1. Due to increased gastric peristalsis. 2. To the hypersecretion which is the result of food retention. 3. To food stagnation within the stomach. 4. To the diminished amount of chyme that enters the bowel forabsorption. T. Increased Peristalsis.—Pain and distress are the inevitable resultsof an increased peristalsis and occur with greatest intensity when theperistalsis is most active.
