Three distinct types of contractions perform colonic motility functions. Rhythmic phasic contractions (RPCs) cause slow net distal propulsion with extensive mixing/turning over. Infrequently occurring giant migrating contractions (GMCs) produce mass movements. Tonic contractions aid RPCs in their motor function. The spatiotemporal patterns of these contractions differ markedly. The amplitude and distance of propagation of a GMC are several-fold larger than those of an RPC. The enteric neurons and smooth muscle cells are the core regulators of all three types of contractions. The regulation of contractions by these mechanisms is modifiable by extrinsic factors: CNS, autonomic neurons, hormones, inflammatory mediators, and stress mediators. Only the GMCs produce descending inhibition, which accommodates the large bolus being propelled without increasing muscle tone. The strong compression of the colon wall generates afferent signals that are below nociceptive threshold in healthy subjects. However, these signals become nociceptive; if the amplitudes of GMCs increase, afferent nerves become hypersensitive, or descending inhibition is impaired. The GMCs also provide the force for rapid propulsion of feces and descending inhibition to relax the internal anal sphincter during defecation. The dysregulation of GMCs is a major factor in colonic motility disorders: irritable bowel syndrome (IBS), inflammatory bowel disease (IBD), and diverticular disease (DD). Frequent mass movements by GMCs cause diarrhea in diarrhea predominant IBS, IBD, and DD, while a decrease in the frequency of GMCs causes constipation. The GMCs generate the afferent signals for intermittent short-lived episodes of abdominal cramping in these disorders. Epigenetic dysregulation due to adverse events in early life is one of the major factors in generating the symptoms of IBS in adulthood.

This book is a unique work devoted to the subject of disordered defaecation. It contains chapters written by experts in the field of ano-rectal physiology and management of disordered defaecation. The various contributions present personal views and special clinical experience of individuals. There are some personal views which we felt should be commented upon and a few areas where the experience of others has been included into the text. For the sake of completeness of each chapter, a slight overlap in some cases was inevitable. We hope the book will serve as a useful collection of opinions on a subject which until recently has been largely ignored by the medical profession.

Constipation and incontinence are of considerable importance to a great number of patients but many put it under taboo. Both functional disturbances comprise a wide spectrum of pathophysiological findings of neuro-muscular changes of the colon or the pelvic floor, but psychological factors may play an important role as well. In recent years much progress has been made in several disciplines which are important for the understanding and handling of constipation and incontinence. This volume, the proceedings of Falk Symposium No. 95 held in Freiburg, Germany, October 28-30, 1996, concentrates on clinically relevant and open questions rather than trying to cover the whole field in all details.

The only book to deal specifically with constipation for specialists has been updated to include all the new advances since the first edition (1995). These advances include biofeedback, surgery for constipation, sacral nerve stimulation, the use of laparoscopy for rectal prolapse, treament and our understanding of some of the psychological problems of these patients. Innovations also include Professor Norman Williams’ Malone Procedure and the newer pharmacologic treatments such as nitric oxide and botulinum toxin injections.

This book describes the causes and clinical management of functional gastrointestinal disorders in a readily understandable way, with the aid of many clear illustrations. The concrete and practical advice provided will be most helpful in the clinical practice of both the general practitioner and the medical specialist. Functional disorders of the gastrointestinal tract, such as gastroesophageal reflux disease, functional dyspepsia, and irritable bowel syndrome, are very common and chronic conditions. Despite the recent publication of many scientific papers on their diagnosis and treatment, much remains unclear, and management is still considered challenging. This practice-oriented book will be an ideal source of reliable up-to-date guidance for all who care for these patients.
