Portal hypertensive enteropathy (PHE) is the appearance of intestinal mucosal capillary stasis and expansion,ultrastructural changes in mucosal epithelial cells, and ectopic varicose veins in patients with portal hypertension (PH), and its scope is limited to intestinal lesions characterized by vascular changes. PHE, including portal hypertensive small bowel disease and portal hypertensive colonopathy (PHC), is one of the important causes of PH complicated by gastrointestinal bleeding. The pathogenesis of PHE is not fully understood, the lack of specificity of histopathological findings, atypical clinical symptoms, and the uniqueness of anatomical location makes its diagnosis difficult. Abdominal CT, multi-slice spiral CT perfusion imaging, 99mTc-RBC and single photon emission CT (SPECT)/CT can provide certain diagnostic information and help guide follow-up treatment. This article summarizes the research progress of PHE from the aspects of pathogenesis, histopathological findings, clinical manifestations,examination and diagnosis and treatment methods, in order to deepen clinicians' understanding of this disease.
