Intestinal Transit time is Related with Different Anorectal Motility Patterns in Chronic Non-Organic Constipation
Constipation is a symptom common to many and different dis eases. It is due, at any rate, to an altered transit of intestinal contents, but it can be a secondary symptom in an organic intestinal and extraintestinal disease, or it can be caused by a primary motor disorder of the bowel. Also in this latter case constipation may be either the main or the only symptom, or it may belong to the wide range of the irritable bowel syndrome. On the other hand, even the definition of constipation is controversial: constipation may be defined as a reduced frequency of evacuations, as a difficulty in stools expulsion or as expulsion of too small stools. For all these reasons, the patients suffering from constipation do not make a homogeneous group. The studies aiming at investigating the intestinal motor alterations responsible for constipation, should consider this problem and should therefore be carried out for cases selected according to clear nosological criteria.
