Abstract

There has long been disagreement about various aspects of the structure and function of the “gatekeeper” (Greek pyloros, from pyle = gate and ouros = guard). In recent years the problem has often been mentioned in anatomy, physiology, gastroenterology, radiology and even in nuclear medicine. For instance, while referring to manometric and gastric emptying studies, Schuurkes and van Nuenten (1984) pointed out that there was considerable controversy as to whether a true pyloric sphincter existed in most species, and especially in man.
