Literature evidence is restricted to pairwise analysis and PD versus POEM comparison is missing. The aim of this network meta-analysis (NMA) was to comprehensively compare outcomes within these three surgical approaches with those of esophageal achalasia.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Materials and Methods:<\/jats:title>\n                    <jats:p>PubMed, EMBASE, and Web of Science databases were consulted.

Overall, 50.4% underwent LHM, 42.8% PD, and 6.8% POEM. The postoperative dysphagia remission was statistically significantly improved in POEM compared with LHM and PD (risk ratio [RR]\u2009=\u20091.21; 95% credible intervals [CIs]\u2009=\u20091.04\u20131.47 and RR\u2009=\u20091.40; 95% CIs\u2009=\u20091.14\u20131.79, respectively). Postoperative gastroesophageal reflux disease (GERD) rate was higher in POEM than in LHM and PD (RR\u2009=\u20091.75; 95% CIs\u2009=\u20091.35\u20132.03 and RR\u2009=\u20091.36; 95% CIs\u2009=\u20091.18\u20131.68, respectively). Postoperative Eckardt score was significantly lower in POEM than in LHM and PD (standardized mean difference (smd)\u2009=\u2009\u22120.6; 95% CIs\u2009=\u2009\u22121.4 to \u22120.2 and smd\u2009=\u2009\u22121.2; 95% CIs\u2009=\u2009\u22122.3 to \u22120.2, respectively).
