Battle of the balloons: which achalasia treatment wins?
NCT ID NCT01793922
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study compared two procedures for treating achalasia, a condition where the esophagus doesn't relax properly. One is a balloon dilation (pneumodilation) and the other is a surgery called POEM done through a scope. 132 adults with achalasia were randomly assigned to one treatment. The goal was to see which provides longer-lasting symptom relief, measured by a symptom score. The study also tracked quality of life after treatment.
