Abstract
The aim of this study was to investigate the long-term clinical outcome of the laparoscopic Heller Dor procedure for esophageal achalasia. A total of 71 consecutive patients with a minimum 6 year follow-up were evaluated. These patients were seen at 1 and 6 months after the operation (at which time barium swallow, endoscopy, manometry, and pH monitoring were performed), and annually thereafter. A dedicated symptom score, that combined severity and frequency of symptoms was used. The median symptom score decreased from 22 (range, 9-29) preoperatively to 4 (range, 0-16) at last follow-up, (p < 0.01). During the follow-up period, 13 patients suffered symptom recurrence; seven of them (54%) had already been diagnosed at the 1-year follow-up. All of these patients were treated with complementary pneumatic dilations. Overall, at a minimum of 6- years after the operation, 81.7% of the patients were satisfied with the treatment and were able to eat normally. The long-term outcome of laparoscopic surgical treatment of esophageal achalasia is only slightly affected by the length of the follow-up and most of the symptomatic failures occur in the early period after the operation.
