Chapter 36 (page 182)
It is not unusual for pedunculated polyps in the pyloric sphincteric cylinder to be
extruded into the duodenum. Consequently they may be visualized either in the pyloric
region of the stomach or in the duodenum at a single radiographic examination.
The 2 cases described here had sessile polyps on the mucosa of the sphincteric cylinder.
During contraction of the latter the polyps moved in an orad direction, and with maximal
contraction were clearly situated farther from the pyloric aperture than in the partially
contracted or non-contracted phases. This seems to confirm the fact that the pyloric
mucosa may move in an orad direction during contraction of the sphincteric cylinder, a
phenomenon first described by Golden (l937) (Chap 13).
