Delayed esophageal emptying of a radiolabeled meal distinguished symptomatic achalasia patients from asymptomatic controls. Esophageal emptying of the isotope meal significantly improved in ten achalasia patients after pneumatic dilation, and in one patient after surgical myotomy. The emptying curve in some patients after treatment simulated that of control subjects. Quantitation of esophageal emptying by a radiolabeled meal is a physiologic test that may be useful in evaluating results of therapy for achalasia.
放射性标记餐的食管排空延迟可将有症状的贲门失弛缓症患者与无症状对照区分开来。10例贲门失弛缓症患者在气囊扩张后，1例患者在手术肌切开术后，同位素餐的食管排空显著改善。部分患者治疗后的排空曲线类似于对照受试者。通过放射性标记餐对食管排空进行定量是一项生理测试，可能有助于评估贲门失弛缓症的治疗效果。
