Before proceeding to a detailed analysis of the findingsobtained in these eight hundred enemas, a general definitionof terms may prevent misunderstanding. (See Table one.) A pelvic colon that does not rise out of the true pelvisduring the filling process is regarded as fixed, while onethat rises above the umbilicus is regarded as being ab-normally placed, provided it does not descend when thetension of filling has been removed.
