K31: Other diseases of stomach and duodenum
K31.7: Polyp of stomach and duodenum
The stomach is located in the upper abdomen. The stomach has a curved shape, and is connected to the gullet (oesophagus) at its upper end and with the first part of the small intestine at its lower end. Between the stomach and the small intestine there is a circular sphincter, the pylorus. The inside of the stomach is lined with mucous membrane. The first part of the small intestine is also called the duodenum. This part is directly connected to the stomach and the lower part of the small intestine. The small intestine is lined with mucous membrane.
You have a protrusion in the mucous membrane of your stomach or the first part of your intestines. The mucous membrane is made up of many individual building blocks, the cells. A mucous membrane protrusion develops when the cells of the mucous membrane proliferate. A mucous membrane protrusion does not usually cause any symptoms. However, some mucous membrane protrusions may also bleed or cause a constriction of the stomach or intestines.
