Sonographic findings of Juxta- and subdiaphragmatic esophagus

During two months from May, 1989, sonographic findings of Juxta- and subdiaphragmatic esophagus were obtained in 120 cases (88%) among 137 cases of normal patients. The esophageal wall is seen as three different echoic layers; hyperechoic mucosa, hypoechoic intervening layers, hyperechoic adventitia. The esophageal image is truncated horn shape (66%) and tubular shape (34%) on longitudinal section, and oval shape (97%) on cross section. The quality of esophageal image is intimately proportionate to the degree of the development of left lobe of liver. On abdominal ultrasonogram, the normal esophageal image of Juxta- and subdiaphragmatic esophagus will be used for evaluation of the pathology of the esophagus
