[Double-contrast with insufflated barium-meal technic in the routine radiological study of the esophagus].

The results are reported of the esophagus double contrast examination with "Insufflated Barium Meal" technique as first part of the routine upper digestive system radiological examination. This technique gives good double contrast without those artifacts using effervescent powders and without modifying the normal radiological alimentary tract examination established way. The double contrast is administered by a special container with a built-in mouthpiece which allows the simultaneous ingestion of barium suspension and air. The esophageal mucosa can be examined as far as the distal tract where frequently the barium contrast stops using different techniques. Good results in 90% of patients have been obtained. The early detection of inflammatory and tumoral lesions has taken particular advantage in patients sometimes asymptomatic.
