Abstract
- Background: Although per oral endoscopic myotomy (POEM) has shown to be beneficial for the treatment of achalasia, it can be difficult to predict who will have a robust and long-lasting response. Historically, it has been shown that higher lower esophageal sphincter pressures have been associated with poorer responses to alternative endoscopic therapies such as Botox therapy and pneumatic dilation. This study was designed to evaluate if modern preoperative manometric data could similarly predict response to therapy after POEM. Methods: This was a retrospective study of 237 patients who underwent POEM at a single institution over a period of 13 years (2011–2023) and who had a high-resolution manometry performed preoperatively and an Eckardt symptom score performed both preoperative and postoperatively. The achalasia type and integrated relaxation pressures (IRP) were tested for potential correlation with the need for any further achalasia interventions postoperatively as well as the degree of Eckardt score reduction using a linear regression model. Results: The Achalasia type on preoperative manometry was not predictive for further interventions or degree of Eckardt score reduction (p = 0.76 and 0.43, respectively). A higher IRP was not predictive of the need for further interventions, however, it was predictive of a greater reduction in postoperative Eckardt scores (p = 0.03) as shown by the non-zero regression slope. Conclusion: In this study, achalasia type was not a predictive factor in the need for further interventions or the degree of symptom relief. Although IRP was not predictive of the need for further interventions, a higher IRP did predict better symptomatic relief postoperatively. This result is opposite that of other endoscopic treatment modalities (Botox and pneumatic dilation). Therefore, patients with higher IRP on preoperative high-resolution manometry would likely benefit from POEM which provides significant symptomatic relief postoperatively. [ABSTRACT FROM AUTHOR]
