Barium radiology is the investigation of choice in patients who present with dysphagia. The barium column distends the oesophagus and shows the extent and severity of any narrowing that is present. A barium swallow should be performed without delay when a constricting disorder of the oesophagus is suspected.
对于出现吞咽困难的患者，钡剂造影是首选的检查方法。钡剂柱可使食管扩张，并显示出存在的任何狭窄的程度和严重程度。当怀疑有食管狭窄性疾病时，应立即进行钡剂吞咽检查。
