Fluoroscopy
Upon administration of oral contrast, radiographs show a displaced gastroesophageal junction located above the diaphragm. The cardia, fundus, and proximal body of the stomach also protrude superiorly into the thorax through the esophageal hiatus, with the middle body constricted at the diaphragmatic opening. The distal body, antrum, and pylorus are intra-abdominal in location.
