Dilation of the Esophagogastric Junction with a New Balloon Device

Achalasia is characterized by lack of relaxation of the esophagogastric junction (EGJ) and lack of peristalsis in the body of the esophagus. EGJ outflow obstruction (EGJOO) with preserved esophageal peristalsis is another disorder considered by some to fall within the spectrum of achalasia. In a retrospective study at four expert centers, researchers evaluated the performance of a new 30-mm balloon device for evaluating EGJ relaxation and providing forceful dilation in 51 patients with EGJOO (n=14) or achalasia (n=37). The primary endpoints were clinical success, based on symptom improvement using a validated scale, and adverse events.

Median follow-up was 180 days. Clinical success was achieved in 64% of patients with achalasia and in 33% o…
