Peroral Endoscopic Myotomy Versus Heller Myotomy for Achalasia: Pros and Cons

Achalasia is an esophageal motor disorder that has multiple endoscopic and surgical methods of treatment. However, there is no consensus on optimal therapy in patients suffering from this disorder. This review discusses two therapies with similar but technically different concepts, peroral endoscopic myotomy and Heller surgical myotomy. After a brief introduction to the basic problems of achalasia, technical considerations, intra and postprocedural complications are presented and the advantages and disadvantages of the two procedures are discussed, based on the relevant articles in the literature. Heller surgical myotomy and peroral endoscopic myotomy appear to be similar in performance with similar results in terms of gastroesophageal reflux rates. However, with experience being gained in the field of endoscopic myotomy, this procedure seems more advantageous, with similar success rates to those of the established surgical technique, but offering shorter operating times, shorter hospitalizations and, ultimately, lower costs.
