[Prospective evaluation of gastroesophageal reflux in patients with achalasia treated with pneumatic dilatation, thoracic or abdominal myotomy].

Abstract

Prevalence of GER in achalasia patients treated with pneumatic dilation and surgical myotomy was high. We suggest the inclusion of 24 hr esophageal pH-metry in the follow-up due to the significant prevalence of asymptomatic GER. Minimal hiatus dissection and antireflux procedure were surgical factors related with a lower frequency of GER after achalasia myotomy.
