Angular incisure

Anatomical feature of the stomach

The angular incisure (also known as the incisura angularis) is a small anatomical notch located on the lesser curvature of the stomach. It is an important landmark in the anatomy of the stomach and plays a role in the division of the stomach into different regions.

Anatomy

The angular incisure is situated on the lesser curvature of the stomach, which is the shorter, concave border of the stomach. It is located approximately two-thirds of the way along the lesser curvature, closer to the pyloric end of the stomach. The incisure marks the junction between the body of the stomach and the pyloric antrum.

Function

The angular incisure serves as a point of reference in the stomach. It helps in distinguishing the body of the stomach from the pyloric region. This distinction is important for understanding the functional anatomy of the stomach, as the different regions have different roles in digestion.

Clinical significance

In clinical practice, the angular incisure is used as a landmark during endoscopy and gastrectomy procedures. It is also a reference point in the diagnosis and treatment of various gastric conditions, such as peptic ulcer disease.
