Pyloric Antrum Lesions

Pyloric antrum lesions affect the lower part of the stomach, known as the pyloric antrum. This section plays a crucial role in digestion by mixing food with digestive juices and regulating the passage of partially digested food into the small intestine. Understanding these lesions, their causes, symptoms, and treatment options is essential for effective management and recovery.

The pyloric antrum is the lower portion of the stomach, just before the pylorus, which is the valve leading into the small intestine. It helps grind food, mix it with stomach acids and enzymes, and regulate its passage into the duodenum.

Types of Pyloric Antrum Lesions

Pyloric antrum lesions can vary widely. Here are some common types:

1. Erosive Lesions: Damage to the lining of the pyloric antrum.
2. Ulcers: Sores that develop on the lining.
3. Polyps: Abnormal growths that can be benign or malignant.
4. Gastritis: Inflammation of the stomach lining.
5. Cancer: Malignant tumors in the pyloric antrum.
6. Gastrointestinal Bleeding: Bleeding in the pyloric antrum area.
