Evaluation of Gastrointestinal Motility and its Disorders


Book Description

This multi-authored book covers most aspects of evaluation of gastrointestinal motility – a field that has been expanding in recent times largely due to advances in diagnostic modalities; coupled with this, new evidences supporting best practices have increased the interest among clinical gastroenterologists, researchers, teachers and trainees in gastrointestinal motility and its disorders. New advances in the field of evaluation of functional bowel diseases and motility disorders, such as high-resolution manometry, 24-h pH impedance monitoring, Bravo capsule pH-metry, barostat, balloon expulsion test, barium and MR defecography, biofeedback, hydrogen breath tests, motility capsule (smartpill) etc. have significantly expanded the scope and outcome of treating these disorders. The chapters have been contributed by a well-conversant group of experts from the global academia, including India, Singapore, Thailand, Korea and Australia, integrating the body of knowledge on evaluation methods with evidence of best practices for the management of motility disorders. A chapter on how to set-up a manometry laboratory provides key information for clinicians and researchers who are planning to start working in this area. With 11 chapters in the book supported with numerous tables, flow charts, schematic diagrams and images, professionals will find it an essential reading. ​




Colonic Motility


Book Description

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.

It also comprises sections on immunopharmacology, dermatological, and ocular pharmacology providing valuable insights into these emerging and recent topics. Covering the diverse groups of drugs acting on different systems, the book reviews their actions, clinical uses, adverse effects, interactions, and subcellular mechanisms of action. It is divided into 11 parts, subdivided into several chapters that evaluate the basic pharmacological principles that govern the different types of body systems. This book is intended for academicians, researchers, and clinicians in industry and academic institutions in pharmaceutical, pharmacological sciences, pharmacy, medical sciences, physiology, neurosciences, biochemistry, molecular biology and other allied health sciences.




Gastrointestinal Motility


Book Description

Gastrointestinal motility has evolved from an esoteric laboratory tool into a sophisti cated diagnostic technique that is now widely used clinically to guide in management of complex gastrointestinal problems. Today, it is the most rapidly growing subspecialty within gastroenterology. Previously, many of the gastrointestinal motility problems were either ignored or attributed to a disturbance of "psyche." But with the growing knowledge and understanding of how a dysfunction of the gastrointestinal muscle and nerves can cause disease, we are at the threshold of a revolution in our approach to the diagnosis and treatment of gastrointestinal motility disorders. The purpose of this book is to serve as a useful, up-to-date reference manual and guide for the diagnostic and therapeutic approach towards common adult and pediatric gastrointestinal motility problems. In order to enhance the understanding of these disor ders, a problem-oriented approach has been chosen, and wherever possible the authors have provided clinical case scenarios to illustrate their message. The emphasis has been on how to diagnose and treat motility disorders rather than to provide an encyclopedic infor mation. The reference list at the end of each chapter should enable the enthusiast to seek further information. Some of the material presented in this book has been derived from the proceedings of the annual University ofIowa College of Medicine GI Motility Symposia.




A Guide to Gastrointestinal Motility Disorders


Book Description

​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.
