Learning objectives This work aims to summarize and schematize most typical barium swallow radiological characteristics of some the most common esophageal and gastric pathologies, as well some incidental or less common findings.
Read more Background Barium contrast swallow or esophagogram is a positive radiographic contrast medium for evaluation of gastrointestinal disorders and has been associated as one of the initial applications of X-rays in medicine. The arrival of ultrasonography, endoscopy, computed tomography and magnetic resonance relegated barium examinations to a lesser degree of importance. These ‘new’ techniques are more invasive, time consuming, expensive, and not without ambiguity or complications. Barium swallow is particularly helpful to evaluate structural characteristics of swallowing mechanics at pharyngeal level, morphological...
Read more Findings and procedure details Within this study, the most typical barium swallow radiological characteristics of some esophageal and gastric pathologies will be exposed, such as esophageal diverticula, acalasia, diffuse esophageal spams, esophageal stenosis, Shatzki ring, hiatal hernia, gastroesophageal reflux , gastric diverticula and post-surgical radiologic aspect of Nissen fundoplication. Also less common findings like laryngeal aspiration or retention of contrast material in the pyriform sinuses and vallecula will be addressed.Achalasia  is characterised by the absence of primary peristalsis in the esophagus and incomplete relaxation...
Read more Conclusion Although barium contrast swallow has long been replaced by other methods, it remains useful and is a noninvasive and readily performed technique, requiring only radiographic still-image capability and a contrast medium, avoiding the long waiting lists of the high demand diagnostic methods.
