Motility disorders of the esophagus: diagnosis with barium-rice administration.
OBJECTIVE
To evaluate the role of barium-rice administration for a standardized diagnosis of dysphagia and esophageal motility disorders.


METHODS
Sixty healthy volunteers and 218 patients with various esophageal disorders (achalasia, scleroderma and other connective tissue diseases, neurologic diseases, esophagitis and others) were examined both by a conventional barium study and by a barium-rice study. The barium-rice meal consisted of barium sulfate and boiled rice, mixed half and half. The time required for esophageal clearance of one sip was measured.


RESULTS
Normal esophageal transit time in healthy controls was between 5 and 15 s for both methods. In patients, the conventional barium study revealed a prolonged transit time in only 16.5% (36 of the 218 cases). The barium-rice study was abnormal in 51.8% (113 of 218 cases), independent of the underlying disease. The barium-rice study was pathological in 77 of those 182 patients (42.3%) who had normal barium transit time. In 24 patients the radiologic results was confirmed by endoscopy and manometric measurements.


CONCLUSIONS
Esophageal motility abnormalities are detected by a barium-rice study with a high sensitivity. With this simple and low-cost method, quantitative and reproducible results can be obtained. Barium-rice administration is a suitable tool for screening and follow-up of patients with dysphagia and esophageal motility disorders.
