Ileocaecal valve

Ileocaecal valve is a part of the human digestive system that connects the ileum (the last part of the small intestine) to the caecum (the first part of the large intestine). It plays a crucial role in digestion by controlling the flow of chyme from the small intestine to the large intestine and preventing the backflow of contents.

Anatomy[edit | edit source]

The ileocaecal valve, also known as the Bauhin's valve, is a sphincter muscle valve that separates the small intestine from the large intestine. It is located in the lower right quadrant of the abdomen. The valve is usually 2 inches in length and is surrounded by the ileocaecal fold, a peritoneal fold.

Function[edit | edit source]

The primary function of the ileocaecal valve is to prevent the backflow of contents from the large intestine into the small intestine. It also slows down the passage of chyme from the ileum to the caecum, allowing for further digestion and absorption of nutrients in the small intestine.

Clinical significance[edit | edit source]

Diseases and conditions that can affect the ileocaecal valve include Crohn's disease, appendicitis, and ileocaecal valve syndrome. These conditions can cause symptoms such as abdominal pain, diarrhea, and weight loss.

Crohn's disease[edit | edit source]

Crohn's disease is a type of inflammatory bowel disease that can affect any part of the gastrointestinal tract, including the ileocaecal valve. Inflammation of the valve can cause symptoms such as abdominal pain and diarrhea.

Appendicitis[edit | edit source]

Appendicitis is an inflammation of the appendix, a small pouch that is attached to the caecum near the ileocaecal valve. If the appendix becomes inflamed, it can put pressure on the valve and cause abdominal pain.
