Clinical bottom line
Laparoscopic Heller Myotomy (LHM) and Peroral Endoscopic Myotomy (POEM) are two primary surgical interventions for achalasia, a disorder characterized by difficulty in swallowing due to esophageal motility issues. Both procedures aim to relieve symptoms by disrupting the lower esophageal sphincter. Current evidence suggests that both LHM and POEM are effective, with POEM offering a less invasive approach. However, the choice of procedure may depend on patient-specific factors, including age, comorbidities, and anatomical considerations.
What the evidence shows
Recent studies and systematic reviews have compared the efficacy and safety of LHM and POEM. A systematic review by Schlottmann et al. (2018) found that both procedures significantly improve dysphagia scores, but POEM may offer a slight advantage in terms of shorter recovery time and less postoperative pain (PMID: 29906463). Another study by Werner et al. (2019) demonstrated that POEM is associated with a higher incidence of gastroesophageal reflux disease (GERD) post-procedure, which is a critical consideration in patient management (PMID: 30601758).
A randomized controlled trial by Ponds et al. (2019) compared the two techniques and reported that both were equally effective in symptom relief at a one-year follow-up, but POEM had a higher rate of reflux esophagitis (PMID: 30995324). This highlights the importance of considering long-term outcomes and potential complications when choosing the surgical approach.
Caveats and uncertainty
While both LHM and POEM are effective, the choice of procedure should be individualized. The higher incidence of GERD following POEM is a significant concern, and patients may require long-term proton pump inhibitor therapy. Additionally, the long-term durability of POEM compared to LHM is still under investigation, with some studies suggesting a potential for increased recurrence of symptoms over time with POEM.
The learning curve for POEM is also steeper, requiring specialized training and experience. This may limit its availability in some clinical settings. Furthermore, the lack of long-term data beyond five years for POEM necessitates cautious interpretation of current findings.
How this may change practice
The decision between LHM and POEM should be guided by patient preferences, anatomical considerations, and the surgeon's expertise. POEM may be preferable for patients seeking a less invasive option with a quicker recovery, provided they are counseled about the potential for increased GERD. Surgeons should ensure they are adequately trained in POEM and consider collaborating with gastroenterologists for comprehensive management of achalasia.
As more long-term data becomes available, practice guidelines may evolve to better define the roles of LHM and POEM in treating achalasia. Clinicians should stay informed about emerging evidence to optimize patient outcomes.
