Endoscopic ultrasound in the diagnosis of Ménétrier's disease: unique contribution.

Ménétrier's disease is a rare gastritis. Although there were some pathological features under gastroscopy, the depth of mucosal infiltration observed was not enough, and it was difficult to distinguish from other gastric mucosal lesions. A biopsy guided by gastroscopy is not deep enough and may lead to misdiagnosis due to incomplete sampling of the entire gastric mucosa. Endoscopic ultrasound offers a unique ability to diagnose this condition by clarifying the origin, blood supply and relationship to adjacent tissues and organs, providing a basis for further differential diagnosis.
