Which factors influence decision making between POEM and Heller myotomy?

• A. Patient anatomy and motility pattern, surgeon experience, comorbidities, and potential postoperative reflux risk
• B. Age and smoking status only
• C. Cost only
• D. Hospital location determines the choice

Answer: (A)

The decision between POEM and Heller myotomy hinges on how the esophagus and LES are failing to relax and the overall context of the patient, not on simple factors like age or cost. Understanding the patient’s motility pattern and anatomy is central: the specific achalasia subtype and the length and location of the nonrelaxing segment guide how much and where to cut. POEM offers a highly customizable, longer myotomy that is particularly useful for distal or spastic segments, while Heller myotomy with fundoplication is a well-established approach that closely controls the anti-reflux outcome through the added wrap.

surgeon experience matters because POEM is technically demanding and outcomes improve with greater expertise in endoscopic myotomy, whereas Heller is a laparoscopic procedure with its own learning curve. The patient’s comorbidities also play a role, as some conditions may favor a shorter, more expedient procedure or influence anesthesia risk and recovery planning.

Finally, reflux risk is a practical consideration: POEM can leave the LES without an anti-reflux mechanism, so reflux and its consequences are more likely compared to Heller with fundoplication. If a patient has significant baseline GERD or is particularly sensitive to reflux, that factor can steer the choice toward Heller with anti-reflux protection.

In short, match the procedure to the esophageal physiology and anatomy, weigh the surgeon’s experience, consider comorbidities, and weigh the reflux implications to determine the best option.
