Long-term results of esophagomyotomy for achalasia of esophagus.

Modified Heller's esophagomyotomy for achalasia of the esophagus was done in 145 patients at Henry Ford Hospital, Detroit, from 1951 to 1977. Information on current symptoms was obtained for 121 patients from a detailed questionnaire that was sent to all patients, from personal interviews, or from data obtained from patients' clinical records. Average period of follow-up was 85 months. Actuarial analysis of postoperative symptoms showed an incidence of reflux of 24% after one year and 48% after ten years; incidence of relief of dysphagia was 89% of all patients after one year and 81% after ten years. Continual surveillance of patients after esophagomyotomy must be stressed. Dissatisfaction with the results of this procedure prompted us to recommend that an antireflux operation be performed at the time of the initial procedure.
