However, these irregularitiesshift with changes in position of the patient and there is no inter-ference with peristalsis. Papillomata produce a defect similar tothat seen in large foreign bodies, but there is little displacement of.

Changes in Peristalsis.—Increase in the depth or speed of wavesmay be due to reflex or irritative causes or compensatory to adiseased pylorus. In the early stages of pyloric obstruction thewaves are deep and vigorous. They may bisect the stomach, giving STOMACH 165 it the appearance of a row of balls. The waves also start higher andmore are visible at the same time. Peristaltic waves are lost inachylia, in the stage of decompensation of pyloric stenosis, in infil-
