Radiology of the Lower Esophageal Sphincter and Stomach in Patients with Swallowing Disorders

The lower esophageal sphincter and gastric fundus are challenging anatomical areas to evaluate radiologically. By visualizing the esophagogastric region and the stomach in mono- and double-contrast technique and recording it on videotape, it is an excellent method for evaluating patients with suspected abnormalities or noncharacteristic swallowing disorders. Additionally, in patients after antireflux procedures or bariatric surgery, swallowing studies and CT have proven to be workhorses for the radiological diagnosis of postoperative complications. Examinations should be tailored according to the individual anatomical situation and the patients’ symptoms.
