Not to be confused with Pillory.
The pylorus (pronounced /paɪˈlɔrəs, pɪˈlɔrəs/; from the Greek πυλωρός, "gate guard") is the region of the stomach that connects to the duodenum. It is divided in two parts:
The pyloric 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 sympathetic innervation from celiac ganglion.
[edit] Medical significanceOne medical condition associated with the pylorus is pyloric stenosis. In such conditions as stomach cancer, tumours may partly block the pyloric canal. A special tube can be implanted surgically to connect the stomach to the duodenum so as to facilitate the passage of food from one to the other. This tube is called a "pyloric stent." [edit] Gallery[edit] In Popular CultureIgnatius J. Reilly, the hero of John Kennedy Toole's tragicomic tale, A Confederacy of Dunces, complains frequently about problems with his pyloric valve.
