Sizing Protocol Does Not Impact Outcomes of Magnetic Sphincter Augmentation

Sizing protocol (pop+2 vs pop+3) in magnetic sphincter augmentation did not impact outcomes like dysphagia, ph normalization, or need for dilation or removal. Upsizing did benefit patients with poor peristalsis or hypercontractile esophagus. Device size increase correlated with demographic and preoperative characteristics, suggesting it is a surrogate for esophageal circumference.
