Both per oral endoscopic myotomy (POEM) and laparoscopic Heller myotomy (LHM) deliver similar outcomes for treating Type III achalasia, suggesting flexibility in surgical approach.

• Success rates post-procedure were nearly identical: 88% for POEM (14 of 16) vs. 87% for LHM (26 of 30), with p=0.94.
• Re-intervention rates were also similar: 25% for POEM and 16.7% for LHM, with no significant difference (p=0.49).

Surgeons can confidently choose either method with expectations for comparable efficacy.
