Aspiration of barium sulphate in swallow study

Abstract

Barium swallow is the simple, common routine procedure for the examination of the oropharynx and oesophagus. Aspiration of barium sulphate is a well known complication, occurs accidentally during contrast enhanced examinations of the upper gastrointestinal system. It is reported either as rare or frequent, based on severity of the cases. Certain conditions affecting the anatomical and functional integrity of the oropharynx and oesophagus act as predisposing factors Due to relatively non-irritant nature of barium sulphate, aspiration into the lungs not expected to cause severe lung injury. However, acute inflammation or even death due to high or low density preparations of barium sulphate, have been reported. We present a case of dysphagia, who developed aspiration of barium, during swallow study and managed conservatively without any delayed complications.
