Abstract
The purpose of this study was to evaluate the role of a "barium-rice" study for diagnosis of dysphagia and oesophageal motility disorders. 203 patients with oesophageal motility disorders of various aetiologies were examined by both conventional barium study and a "barium-rice" study. During the latter, oesophageal clearance of a defined mixture of barium sulfate and boiled rice was measured. The conventional barium study revealed prolonged transit time in only 15.8% (32 of 203 cases), whereas barium-rice study was pathological in 50.8% (103 to 203 cases). In 71 of 171 patients (41.5%) with a normal barium study, barium-rice passage was prolonged. In 23 patients, radiological results were confirmed by manometric measurements. Oesophageal motility disorders are detected by a barium-rice study with high sensitivity independent of the underlying disease. The barium-rice study offers a simple diagnostic tool revealing quantitative and reliable results. The barium-rice study is a suitable method for screening and follow-up of patients with dysphagia and oesophageal motility disorders.
