11.   It is difficult to measure colonic function simultaneously in its various parts and it is erroneous to extrapolate findings from one part to another.

12.   Colonic motor function has also been investigated with electromyography, the electrodes being attached to the mucosa in the intact human.

13.   Even when abnormalities of colonic motor function are identified, it is not clear whether they are responsible for the symptoms.

14.   Thus research into colonic motor function remains a challenging and potentially rewarding area where progress has been facilitated by recent technological advances.

15.   This unquestionable carbohydrate malabsorption, leads to a pronounced change in colonic function and metabolism by stimulating bacterial proliferation.

16.   Our study indicates that there is no systematic change in colonic function after cholecystectomy.
