Summary

This study follows 200 patients who had minimally invasive surgery for conditions like achalasia, GERD, or hiatal hernia. Each year, patients fill out questionnaires about their symptoms and quality of life, and doctors review their medical records. The goal is to understand how well these surgeries work over the short and long term.
