Schatzki Ring
(Schatzki's Ring)

Medically reviewed by: Jay W. Marks, MD

What is a Schatzki ring?

Many years ago, Schatzki described a smooth, benign, circumferential, and narrow ring of tissue in the lower end of the esophagus (the food pipe that connects the mouth to the stomach). These rings are located just above the junction of the esophagus with the stomach. These rings are very common, occurring in more than 6% of the population. The cause of these rings is not clearly understood, while some doctors believe they are caused by long term damage from stomach acid reflux.

What is the esophagus?

The esophagus is a hollow tube that carries food and liquids from the throat to the stomach. When a person swallows, the muscular walls of the esophagus contract to push food down into the stomach. Glands in the lining of the esophagus produce mucus, which keeps the passageway moist and makes swallowing easier. The esophagus is located just behind the trachea (windpipe). In an adult, the esophagus is about 10 inches long.

What is cancer?

Cancer is a disease that affects cells, the body's basic unit of life. To understand any type of cancer, it is helpful to know about normal cells and what happens when they become cancerous.

The body is made up of many types of cells. Normally, cells grow, divide, and produce more cells when they are needed. This process keeps the body healthy and functioning properly. Sometimes, however, cells keep dividing when new cells are not needed....
