OBJECTIVE: To determine whether peroral endoscopic myotomy (POEM) improves esophageal peristalsis and to investigate the association between recovery of esophageal peristalsis after POEM and clinical features of the patients.
METHODS: In this single-center retrospective study, data were collected from medical records of the patients with achalasia who underwent POEM between January 2014 and May 2016. Demographics data, high-resolution esophageal manometry parameters, Eckardt score, and gastroesophageal reflux disease questionnaire (GERD-Q) score were collected. Weak and fragmented contraction was defined as partial recovery of esophageal peristalsis based on the Chicago classification version 3.0. Logistic regression analysis was used to identify variables associated with the partial recovery of peristalsis after POEM.
RESULTS: A total of 103 patients were enrolled. Esophageal contractile activity was observed in the distal two-thirds of the esophagus in 24 patients. The Eckardt score, integrated relaxation pressure, and lower esophageal sphincter (LES) resting pressure were significantly decreased after POEM. Multivariate analysis revealed that preprocedural LES resting pressure (P = 0.013) and preprocedural Eckardt score (P = 0.002) were related to the partial recovery of peristalsis after POEM. Symptoms of gastroesophageal reflux and reflux esophagitis after POEM were less frequent in those with partial recovery of peristalsis (both P < 0.05).
CONCLUSIONS: Normalization of esophagogastric junction relaxation pressure achieved by POEM is associated with the partial recovery of esophageal peristalsis in patients with achalasia. Preprocedural LES resting pressure and the Eckardt score are predictive of the recovery of esophageal peristalsis.
