- Abstract
Background: Peroral endoscopic myotomy (POEM) is a relatively new but increasingly therapeutic option for achalasia. In recent years, POEM has been used for nonachalasia esophageal motility disorders (NAEMDs), such as diffuse esophageal spasm, esophagogastric junction outlet obstruction, and hypercontractile disorder, with some clinical success. No studies thus far compare the outcomes of these two groups. We perform the first head-to-head comparison of outcomes after POEM in patients with achalasia and NAEMD., Patients and Methods: A retrospective analysis of all patients undergoing POEM at one university hospital by a single expert endoscopist from July 2021 to December 2022 was performed. All patients were symptomatic, and the presence of esophageal motility disorders was confirmed using multiple diagnostic modalities. These patients were then divided into 2 groups, achalasia and NAEMD, based on the underlying diagnosis. Statistical analysis of different clinical outcomes, including effectiveness and safety, was performed., Results: Thirty-seven patients (mean age: 59.55, females: 22) underwent POEM in the study period. Twenty patients had achalasia and 17 patients had NAEMD. The median myotomy length was 5.5 cm for the achalasia group and 10 cm for the NAEMD group. This excluded patients with esophagogastric junction outlet obstruction in which the median myotomy length was 3 cm. The procedure time, the duration of hospital stays, the rates of same-day discharge, and complications were similar between the two. Short-term outcomes of POEM for the two groups were similar with improvement in 94% of patients in the achalasia group and 93.75% in the NAEMD group., Conclusion: Contrary to prior observations, our study highlights that POEM is equally effective in achieving clinical improvement in patients with NAEMD as achalasia over 6 months of follow-up. In addition, POEM has a comparable safety profile in both patient groups making it a feasible therapeutic option for these debilitating and challenging disorders., Competing Interests: The authors declare no conflicts of interest., (Copyright © 2023 Wolters Kluwer Health, Inc.
