Official title
PREcision MEDicine In Achalasia - A Multicenter Randomized Non-Inferiority Clinical Trial of Short Tailored POEM vs. Standard POEM for Non-Spastic Achalasia and A Multicenter Prospective Cohort Study of Long Tailored POEM for Spastic Esophageal Motility Disorders
Overview
The goal of this observational study is to learn about how the doctor decides how long to cut t the esophageal muscle during Per-Oral Endoscopic Myotomy (POEM) in patients with difficulty swallowing due to certain conditions. The main question it aims to answer is: does pre-POEM testing help the physician choose how long to cut the muscle. Participants will allow researchers to access their standard of care information in their medical record, complete questionnaires at up to 6 times over a 2-year period.
Primary outcome measures
- Clinical Response-Overall [Time frame: From enrollment to Year 2]
- Clinical Response-by Sex [Time frame: From enrollment to Year 2]
- Clinical Response-by Race [Time frame: From Enrollment to Year 2]
- Clinical Response-by Ethnicity [Time frame: From Enrollment to Year 2]
