Abstract
Constipation is today treated by adding non-absorbable fibres to a normal diet. the aim of this investigation was to study the influence of fibres on colon cleansing results in patients referred for double contrast examination of the colon. A series of 240 consecutive patients were separated into two groups, one treated with one day of starvation and the routine cleansing regimen, the other group with wheat fibres thrice daily for four days before the day of the regular cleansing program. No difference in cleanness between the two groups was seen
