We evaluated the relationship between radionuclide esophageal transit studies and barium swallow appearances in a group of patients following forceful balloon dilatation for the treatment of achalasia of the cardia. Paired erect radionuclide esophageal transit studies and erect barium swallows of a group of patients who had undergone pneumatic balloon dilatation for the treatment of achalasia were analyzed. Indices derived from the radionuclide transit study were the percentage of maximum activity remaining in the esophagus 30 s after swallowing a dilute volume of tracer (A30 s) and the percentage of retained activity remaining at 100 s after washout with a bolus of water (A100 s). Indices derived from the barium swallow were a subjective grading of the degree of esophageal dilatation on a 4-point scale and a similar grading of the maximum distensibility of the gastroesophageal channel. Twenty five pairs of radionuclide and barium studies in 18 patients were analyzed. There was statistically significant correlation between the amount of retained activity on the radionuclide studies and degree of esophageal dilatation on the barium studies (r = 0.69 for A30 s, r = 0.56 for A100 s, P = < 0.01). There was no correlation between the amount of retained activity on the radionuclide studies and the degree of distension of the gastroesophageal channel on barium studies. The relationship between the radionuclide esophageal transit curve and barium appearances of the esophagus following pneumatic balloon dilatation for the treatment of achalasia is complex. The transit study provides unreliable information about the distensibility of the gastroesophageal channel and should not be relied upon in isolation for assessment of the efficacy of treatment.
