title: [Manifestation of abdominal segment of esophagus by body surface ultrasonography and determination of normal values].
abstract: Scanning over the oblique section of xiphoid-left costal margin by body surface ultrasonography was adopted in the present study. The esophageal hiatus showed triangle-like strong echo which was called by the author "Hom Dill Casoue". Its dorsal aspect could be confirmed as the abdominal segment of the esophagus. In a general survey of 268 cases of high risk crowd in high incidence area, 82% (217 cases) were manifested clearly. The mean wall thickness was 2.58 +/- 0.54mm, and the mean length 23.7 +/- 5.6mm. Among the 9 cases suspicious of increased thickness, 5 were confirmed to have esophageal lesions. Among them there were 2 cases of esophageal carcinoma, and 2 cases of inflammatory ulcer with edema, and one case of hiatal hernia. The accuracy rate of diagnosis for those with clear manifestation by ultrasonography reached as high as 98% (218/222 cases). This method provides a new measure for the general survey of esophageal diseases in the abdominal segment.
