Pathophysiology of colonic motility disorders.
When no identifiable organic cause for colonic symptoms can be found, it is easy for the busy clinician to label the patient neurotic. It is evident that many of these "functional" disorders do reflect an underlying motility disorder, although our understanding is far from clear. However, currently, patients with severe constipation are evaluated in a much more rational manner and, as a consequence, are offered a reasonable therapeutic approach that can be predicted to have a good chance for success. We can hope that as our understanding of irritable bowel syndrome is strengthened, treatment will become more efficacious than the unproved and costly medications that are in use currently. Until dietary modification becomes commonplace, it is unlikely that the incidence of diverticular disease or its complications will change. Already, our understanding of ileus has allowed us to realize the benefits of laparoscopic surgery, and as our knowledge of the various gut hormones and the inhibitory role that some play in intestinal motility grows, ileus, and its resulting prolongation of hospital stay, may become less problematic.
