采用标准12.5mm钡片的吞钡试验久已被用于评估食管腔畅通和诊断食管狭窄。本研究前瞻性评估使用标准12.5mm钡片所需的条件,旨在确定钡片成功通过正常食管的最低标准。
The barium test using standard 12.5 mm barium has long been used to assess the esophageal lumen and diagnose esophageal stenosis. This study prospectively evaluated the conditions required for the use of a standard 12.5 mm barium slice designed to determine the minimum standard for successful barium slice passage through normal esophagus.
