New study to track if a simple scope procedure can fix chronic swallowing issues

This study will follow 600 adults who are already scheduled to receive a standard procedure called POEM, which uses a scope to cut tight muscles in the throat or stomach. The goal is to see how well the procedure works over time for conditions like achalasia, gastroparesis, and Zenker's diverticulum. Researchers will measure symptom relief and any side effects like acid reflux.
