Study limitations
The following limitations of this study should be considered before drawing definitive conclusions. The
study was limited to a small number of patients. In addition, the study was retrospective and represented a
highly selected group of patients.

Undoubtedly, the use of robotic technology adds greater cost. If the results of this study are validated by
a randomized prospective study, this shortcoming may be offset by the greater accuracy of dissection, the
high rates of relief of dysphagia, and the low incidence of pathologic reflux associated with robotic lateral
Heller myotomy without fundoplication for achalasia.
