The choice between pneumatic dilatation and surgical esophagomyotomy as the initial treatment for achalasia is controversial. The aims of this study were to determine the long term clinical outcome and costs of treating achalasia initially with pneumatic dilatation as compared to esophagomyotomy. Of 123 patients undergoing an initial pneumatic dilatation for achalasia at our institution from 1976 to 1986, 71 (58%) received no further treatment for achalasia during a mean follow up of 4.7±2.8 years. Only 15 of these 123 patients (12%) eventually underwent surgical esophagomyotomy, (two for perforation during pneumatic dilatation, 13 for persistent or recurrent symptoms). The degree of dysphagia at follow up was improved to a similar degree in patients treated with an initial pneumatic dilatation as compared to patients treated with an initial esophagomyotomy. Patients with age≥45, years at time of initial pneumatic dilatation had fewer subsequent treatments for persistent or recurrent symptoms and had less dysphagia on follow up as compared to patients <45 years. Subsequent pneumatic dilatations to treat persistent or recurrent symptoms were less beneficial than an initial pneumatic dilation. The cost of esophagomyotomy was 5 times greater than the cost of pneumatic dilatation. When costs were analyzed to include subsequent treatments of symptomatic patients, the total expectant costs of treating with an initial esophagomyotomy remained 2.4 times greater than treating with an initial pneumatic dilatation. This study suggests that an initial pneumatic dilatation will be the only treatment needed for the majority of patients with achalasia. A treatment regimen starting with penumatic dilatation has less overall costs than starting with esophagomyotomy. For each subsequent pneumatic dilatation, however, the clinical benefit leans toward, surgery.
