A new method for studying gut transit times using radioopaque markers


A simple technique for measuring gastrointestinal transit times using radioopaque pellets of barium-impregnated polythene has been developed and validated. A normal range has been established by studying 25 normal subjects; all passed the first marker within three days and most passed 80% of the markers within five days.
