Core Tip

Core tip: Cricopharyngeal dysphagia can be treated with endoscopic balloon dilatation. In this series, a novel dilatation technique of pulling a fully inflated 15-20 mm balloon dilator in a retrograde manner across the upper esophageal sphincter was safe and effective for the treatment of cricopharyngeal dysphagia.
