Following Peroral Endoscopic Myotomy (POEM) for Achalasia Esophagram is a Reliable Predictor of Esophageal Contents on EGD

Aims Peroral endoscopic myotomy (POEM) treats achalasia, but patients have higher risk of gastroesophageal reflux (GER) compared to Heller myotomy. Post-POEM endoscopic GER screening is recommended to identify those at risk for reflux-related complications. Due to aspiration risk, endotracheal (ET) intubation is performed on achalasia patients for EGD, though it is unclear if the risk remains after POEM. We aimed to determine if esophagram ≥3 months post-POEM could predict the presence of esophageal contents on EGD.
