The relationship between manometric subtype and outcomes of surgical treatment for patients with achalasia

Background The Chicago Classification describes three distinct subtypes of achalasia and it appears to be a promising tool in predicting results of treatment with standard Heller Myotomy. The aim of this study is to analyze the outcomes of surgical treatment for achalasia using an extended Heller myotomy for each subtype and to identify additional parameters that may predict the success of therapy.
