Introduction:
Laparoscopic Heller myotomy has become the therapy of choice for achalasia. In the last three years, clinical experience with a novel approach to this disease, Per-Oral Endoscopic Myotomy (POEM), has grown.
Methods:
Herein, we describe the technical steps in the POEM procedure.
Conclusion:
In our experience, the method appears to be a safe alternative to standard laparoscopic Heller myotomy, but further assessment is needed to understand long-term outcomes.
