Esophageal dissecans superficialis (EDS) is a rare disease with endoscopic findings of sloughing squamous tissue with underlying normal mucosa and had no known cause. The literature does support possible causality between the presence of an esophageal stricture and EDS however there has been no association to date between EDS and esophagogastric junction outflow obstruction (EGJOO). We present a case of newly diagnosed EGJOO in a patient with long standing gastroesophageal reflux disease who presented with dysphagia. Evaluation identified endoscopically normal mucosa and a diagnosis of esophagogastric junction outflow obstruction on high resolution impedance manometry. A month later, repeat endoscopy identified diffusely sloughing mucosa consistent with EDS. Endoscopic dilation followed by a robotic Heller myotomy with Dor fundoplication to relive the outflow obstruction resulted in resolution of EDS in this case.
