INTRODUCTION: Peroral esophageal myotomy (POEM) is a novel endoscopic treatment for achalasia. It has gained popularity worldwide among surgeons and endoscopists, but no studies have compared peroral endoscopic short with long myotomy for achalasia. We aimed to compare the clinical efficacy and safety between peroral endoscopic shorter and longer myotomy.
METHODS: The retrospective study enrolled 129 achalasia patients who underwent POEM from July 2011 to September 2017. Based on the myotomy length (ML), patients were divided into shorter myotomy (SM) group (ML ≤ 7 cm, n = 36) and longer myotomy (LM) group (ML > 7 cm, n = 74). Procedure-related parameters, symptom scores, adverse events and manometric data were compared between two groups.
RESULTS: The mean ML was 6.0 ± 0.6 cm in SM group, and 11.5 ± 3.1 cm in LM group (p < 0.001). The mean operation time was significantly less in SM group than LM group (46.6 ± 18.5 min vs 62.1 ± 25.2 min, p = 0.001). During a mean follow-up period of 28.7 months, treatment success (Eckardt score ≤ 3) was achieved in 94.4% (34/36) of patients in SM group and 91.9% (68/74) in LM group (p = 0.926). There was no statistical difference in the incidence of intraoperative complications (8.4% vs 8.2%, p = 0.823) and reflux rate (8.3% vs. 14.9%, p = 0.510) between two groups.
CONCLUSIONS: Peroral endoscopic shorter myotomy is comparable with longer myotomy for treating achalasia with regard to clinical efficacy and has the advantage of shorter procedure time.
