[Comparative roentgen study of the small intestine with single and double contrast]

The experiences from a total of 303 small intestine examinations of different techniques show that especially the double-contrast representation using barium sulfate and air achieves the best diagnostical findings. The double-contrast representation can be achieved by an antegrade small intestine enema (enteroclysis) or within the conventional small intestine passage by retrograde air insufflation. These examination techniques make optimal fine diagnostics especially of the lower ileum possible. The indications for the different methods are explained.
