ABSTRACT
BACKGROUND:
Non-achalasia esophageal motility disorders (NAEMDs), encompassing distal esophageal spasm (DES) and hypercontractile esophagus (HCE), are rare conditions. Peroral endoscopic myotomy (POEM) is a promising treatment option. In NAEMDs, unlike with achalasia, the lower esophageal sphincter (LES) functions normally, suggesting the potential of LES preservation during POEM.METHODS:
This retrospective two-center observational study focused on patients undergoing LES-preserving POEM (LES-POEM) for NAEMD. Eckardt scores were assessed pre-POEM and at 6, 12, and 24 months post-POEM, with follow-up endoscopy at 6 months to evaluate for reflux esophagitis. Clinical success, defined as an Eckardt score ≤3, served as the primary outcome.RESULTS:
227 patients were recruited over 84 months until May 2021. Of these, 16 underwent LES-POEM for an NAEMD (9 with HCE and 7 with DES). The median pre-POEM Eckardt score was 6.0 (interquartile range [IQR] 5.0-7.0), which decreased to 1.0 (IQR 0.0-1.8; P<0.001) 6 months post-POEM. This was sustained at 24 months, with an Eckardt score of 1.0 (IQR 0.0-1.8; P<0.001). Two patients (12.5%) developed Los Angeles grade A or B esophagitis.CONCLUSIONS:
LES-POEM for NAEMD demonstrates favorable clinical outcomes, with infrequent esophagitis and reintervention for LES dysfunction rarely required.
