Abstract | Background and aim: Peroral endoscopic myotomy (POEM) is an established treatment for achalasia. In this systematic review and meta-analysis, we aimed to analyze the mid and long-term outcomes of POEM in esophageal motility disorders. Methods: Literature search was performed in databases including PubMed, Embase, Cochrane databases, and Google scholar from January 2010 to May 2021. The primary objective of the study was the clinical success (Eckardt score ≤3 or <4) at mid-term (30 to 60 mo) and long-term (>60 mo) follow-up after POEM. Secondary objectives included post-POEM gastroesophageal reflux (GER) as evaluated by symptoms, increased esophageal acid exposure, and reflux esophagitis. Results: Seventeen studies with 3591 patients were included in the review. Subtypes of motility disorders were type I (27%), type II (54.5%), type III (10.7%), distal esophageal spasm/Jackhammer esophagus (2%), and esophagogastric junction outflow obstruction (17.5%). Pooled mean follow-up duration was 48.9 months (95% CI, 40.02-57.75). Pooled rate of clinical success at mid-term follow-up was 87% (95% CI, 81-91; I2 , 86%) and long-term was 84% (95% CI, 76-89; I2 , 47%). In nonachalasia motility disorders (esophagogastric junction outflow obstruction, distal esophageal spasm, and Jackhammer esophagus), pooled rate of clinical success was 77% (95% CI, 65-85; I2 , 0%). GER as estimated by symptoms was 23% (95% CI, 19-27; I2 , 74%), erosive esophagitis was 27% (95% CI, 18-38%; I2 , 91%), and increased esophageal acid exposure was 41% (95% CI, 30-52; I2 , 88%). Conclusion: POEM is a durable treatment option in cases with achalasia. One-fourth of patients suffer from erosive GER in the long-term and success rates are lower in nonachalasia esophageal motility disorders. |
