K31.A12
Gastric intestinal metaplasia without dysplasia, involving the body (corpus)
Clinical Classification Guidelines
Medical Intelligence & Overview
Gastric intestinal metaplasia without dysplasia is a condition characterized by the replacement of the stomach's normal lining with intestinal-type tissue. This change occurs in the body of the stomach, also known as the corpus. It is considered a precancerous alteration that can increase the risk of developing stomach cancer over time. Often found during evaluations for digestive symptoms, this condition requires attention to prevent progression to more serious gastric diseases.
Causes & Symptoms
Clinical Causes: Chronic Helicobacter pylori infection Long-term gastritis (inflammation of the stomach lining) Autoimmune disorders affecting the stomach Dietary factors such as high salt intake and smoked foods Genetic predisposition Environmental factors, including exposure to certain chemicals or toxins
Key Symptoms: Indigestion or heartburn Bloating after meals Nausea or occasional vomiting Loss of appetite Unexplained weight loss in some cases Blood in stool or anemia (more common in advanced stages)
Diagnostic & Treatment
Diagnosis Path: Diagnosis typically involves endoscopic examination of the stomach, during which tissue samples (biopsies) are obtained. These samples are examined under a microscope to identify intestinal-type lining cells. Additional tests, such as Helicobacter pylori detection, may also be conducted to identify underlying causes. Imaging studies are generally not required unless further complications are suspected.
Treatment Protocols: While gastric intestinal metaplasia itself often does not require immediate treatment, addressing underlying causes is important. Treatment options include:
