Treatment of esophageal achalasia with laparoscopic Heller myotomy and Dor partial anterior fundoplication: prospective evaluation of 100 consecutive patients.
Academic Article
Overview
abstract
In this article we report our experience in 100 consecutive achalasia patients who were treated with laparoscopic Heller myotomy and Dor antireflux fundoplication, with particular regard to the technical problems encountered, the learning curve, and the long-term follow-up. The operation was completed laparoscopically in 94 patients, with a median operative duration of 150 minutes, and a continuous steady reduction in the operating time from the first patients to the last. In six patients the operation was completed through "open" access. Postoperative complications were recorded in six cases. Follow-up was completed in all 100 patients, with a median follow-up of 24 months. Overall, actuarial life-table analysis showed a probability of 90% that patients would be symptom free over a 5-year period. Radiologic assessment showed a significant reduction in the esophageal diameter, and manometry showed a significant reduction in the lower esophageal sphincter resting pressure and residual pressure. Twenty-four-hour pH monitoring showed postoperative reflux in 6.9% of the patients. Persistent dysphagia or chest pain was reported by eight patients, which constituted treatment failures. Seven of these eight patients were eventually treated with multiple pneumatic dilatations, which were successful in six cases. It was concluded that laparoscopic Heller myotomy with Dor fundoplication is a feasible and effective treatment for achalasia, with an actuarial success rate of 90% at 5 years.
