Retreatment after failure of per-oral endoscopic myotomy: Does “cutting” fare better than “stretching”?

We read the article with great interest in which the authors demonstrated the relative efficacies of repeated per-oral endoscopic myotomy (re-POEM), laparoscopic Heller's myotomy (LHM), and pneumatic balloon dilation (PBD) after the failure of primary POEM.1 Although the sample size was small (n = 34), the authors should be congratulated for their efforts.
