Outcomes after minimally invasive esophagomyotomy.
BACKGROUND
Thoracic surgeons traditionally performed thoracotomy and myotomy for achalasia. Recently minimally invasive approaches have been reported with good success. This report summarizes our single-institution experience using video-assisted thoracoscopy (VATS) or laparoscopy (LAP) for the treatment of achalasia.


METHODS
A review of 62 patients undergoing minimally invasive myotomy for achalasia was performed. There were 27 male and 35 female patients. Mean age was 53 years (range 14 to 86). Thirty-seven (59.7%) had failed prior treatments (balloon dilation, botulinim toxin injection, or prior surgery). Outcomes studied were dysphagia score (1 = none, 5 = severe), Short-Form 36 quality of life (SF36 QOL) score, and heartburn-related QOL index (HRQOL).


RESULTS
Surgery included myotomy and partial fundoplication (5 VATS and 57 LAP). Mortality was zero, and complications occurred in 9 (14.5%) patients. There were 6 perforations (4 repaired by LAP and 2 open). Median length of stay was 2 days, time to oral intake was 1 day. At a mean of 19 months follow-up, 92.5% of patients were satisfied with outcome. Dysphagia scores improved from 3.6 to 1.5 (p < 0.01) but 3 patients ultimately required esophagectomy for recurrent dysphagia. HRQOL scores for heartburn and SF-36 QOL scores were comparable with control populations.


CONCLUSIONS
Minimally invasive myotomy and partial fundoplication for achalasia improved dysphagia in 92.5% of patients with heartburn and QOL scores were comparable with normal values at 19-month follow-up. The laparoscopic approach offers excellent results and was the preferred approach by our thoracic group for treating achalasia. Thoracic residency training should strive to include laparoscopic esophageal experience.
