BACKGROUND Early relapse after treatment of achalasia occurs in 10-32 % of patients. The best method to follow up these patients is not known. Symptoms often do not correlate with esophageal clearance: some patients are oligosymptomatic despite persistent esophageal stasis/dilatation. AIM The aim was to compare two methods of measurement of esophageal clearance (impedance manometry with barium swallow) in achalasia patients following treatment. Symptom assessment (Eckardt score/detailed dysphagia questions) was correlated with objective measurements of esophageal stasis (barium swallow and impedance manometry) in achalasia patients following treatment. METHODS Post-treatment patients were followed up after median 38.4 months (median range 1-144 months). Symptoms were quantified using the Eckardt score and detailed dysphagia questions. Timed barium swallow quantified distal esophageal retention 0.5, 1, 3, and 5 minutes after oral contrast and impedance manometry assessed total and segmental esophageal clearance during water/viscous swallows and free drinking (200 mL). RESULTS Thirty-two patients (7 women, age 48.3; range 20-74) completed all investigations. Bolus retention in the distal esophagus assessed by impedance correlated well with barium swallow. There were no differences in impedance and timed barium swallow parameters between patients with Eckardt score 0-2 points or ≥3 points. Nine (28%) patients had an Eckardt score ≥3 points and 21 (66%) had ≥1 point in the detailed dysphagia questions. Patients without any dysphagia history had lower barium column height and width at 3 and 5 minutes compared to those with ≥1 positive answer in the detailed dysphagia questions. Correlation between the Eckardt score and detailed dysphagia questions was moderately good (r = 0.546; p = 0.001). CONCLUSION A detailed history of esophageal dysphagia rather than the Eckardt score is more sensitive to detect oligosymptomatic patients with disturbed esophageal clearance. Impedance manometry correlates well with the timed-barium swallow examination and represents an alternative objective assessment as it avoids radiation exposure.
