[New preparation method for barium enema: efficacy and administration of oral intestinal lavage solution with gastrointestinal prokinetic agent].

The modified Brown's method is commonly used in Japan as preparation for barium enema; however, in a few cases, its cleansing effect is not satisfactory even with the use of adequate diet. To develop a new method of preparation for barium enema, we examined the use of an oral intestinal lavage solution (PEG-ELS) with mosapride and compared it with the modified Brown's method. We administered mosapride and PEG-ELS by four different methods. These methods were assessed by the amount of remaining feces and the adequacy of barium coating. Methods in which mosapride was taken separately before and after the intake of PEG-ELS were more effective than the method using mosapride and the modified Brown's method. Lesion detection was almost the same as that with the modified Brown's method. In conclusion, preparation for barium enema using mosapride before and after PEG-ELS intake is more effective than the modified Brown's method.
