Treatment of esophageal achalasia with Heller myotomy: retrospective evaluation of patient satisfaction and disease-specific quality of life.
BACKGROUND
Prospective randomized studies have suggested that surgery palliates esophageal achalasia more effectively than pneumatic dilatation, but for some dilatation is still the procedure of choice for initial treatment. We decided to compare achalasia symptoms before and after Heller myotomy by means of postoperative questionnaires.


METHODS
The study included 22 patients who underwent Heller myotomy for achalasia at the Hotel Dieu Hospital, Queen's University, Kingston, Ont., since July 1990; 5 of them required repeat myotomy for symptom recurrence, for a total of 9 open and 18 laparoscopic procedures. Median follow-up was 43 (range 6-109) months. Preoperative and postoperative data regarding dysphagia, regurgitation, chest pain and overall patient satisfaction were gathered. Symptom scores were calculated by adding severity (0 = none, 2 = mild, 4 = moderate, 6 = severe) to frequency (0 = never, 1 = occasionally, 2 = once a month, 3 = every week, 4 = twice a week, 5 = daily). Patients having a repeat procedure were instructed to evaluate symptoms with respect to their initial myotomy.


RESULTS
Seventeen (77%) patients were successfully contacted, 4 of them had subsequent repeat myotomy for symptom recurrence. Initially, overall symptom scores decreased for all but 1 patient, with mean preoperative and postoperative values of 23.1 and 7.3 respectively (p < 0.001). The patient in whom symptoms did not improve is a candidate for a repeat procedure. Repeat myotomy was performed after a median of 38 (range 23-75) months, corresponding to an overall 3-year positive outcome in 13 (76%) of the 17 patients. Fifteen (88%) patients considered their myotomies a success and 16 (94%) would choose to have this procedure again given the outcome.


CONCLUSIONS
Heller myotomy appears to be effective in alleviating the symptoms of achalasia. Repeat myotomy is occasionally required.
