The pylorus (from Greek πυλωρος = "gate guard") is the region of the
stomachthat connects to the duodenum. It is divided in two parts:
pyloric antrum, which connects to the body of the stomach.
pyloric canal, which connects to the duodenum.
sphincter, or valve, is a strong ring of smooth muscle at the end of the pyloric canal and lets food pass from the stomach to the duodenum. It receives sympatheticinnervation from celiac ganglion.
One medical condition associated with the pylorus is
pyloric stenosis.In such conditions as stomach cancer, when tumours may partly block the pyloric canal, a special tube can be implanted surgically to connect the stomach to the duodenum to assist food to pass from one to the other. This tube is called a pyloric stent.
In popular culture
John Kennedy Toole's " A Confederacy of Dunces", the protagonist complains frequently about his pyloric valve, which, he claims, opens or shuts according to stress levels.
Umberto Eco's " The Mysterious Flame of Queen Loana", translated from the Italian by Geoffrey Brock, the protagonist, Giambattista Bodoni, alternately describes a tickling or a knot in his pylorus that feels like "a mysterious flame".
