Book excerpt: Deglutition or a swallow begins as a voluntary act in the oral cavity but proceeds autonomously in the pharynx and esophagus. Bilateral sequenced activation and inhibition of more than 25 pairs of muscles of mouth, pharynx, larynx, and esophagus is required during a swallow. A single swallow elicits peristalsis in the pharynx and esophagus along with relaxation of upper and lower esophageal sphincters. Multiple swallows, at closely spaced time intervals, demonstrate deglutitive inhibition; sphincters remain relaxed during the entire period, but only the last swallow elicits peristalsis. Laryngeal inlet closure or airway protection is very important during swallow. Upper part of the esophagus that includes upper esophageal sphincter is composed of skeletal muscles, middle esophagus is composed of a mixture of skeletal and smooth muscles, and lower esophagus, including lower esophageal sphincter, is composed of smooth muscles. Peristalsis progresses in seamless fashion, despite separate control mechanism, from the skeletal to smooth muscle esophagus. The esophagus's circular and longitudinal muscle layers contract synchronously during peristalsis. Sphincters maintain continuous tone; neuromuscular mechanisms for tonic closure in the upper and lower esophageal sphincters are different. Lower esophageal sphincter transient relaxation, belching mechanism, regurgitation, vomiting, and reflux are mediated via the brain stem.

Available in PDF, EPUB and Kindle. Book excerpt: This book offers one of the most comprehensive reviews in the field of gastrointestinal (GI) physiology, guiding readers on a journey through the complete digestive tract, while also highlighting related organs and glandular systems. It is not solely limited to organ system physiology, and related disciplines like anatomy and histology, but also examines the molecular and cellular processes that keep the digestive system running. As such, the book provides extensive information on the molecular, cellular, tissue, organ, and system levels of functions in the GI system. Chapters on the roles of the gut as an endocrine, exocrine and neural organ, as well as its microbiome functions, broaden readers’ understanding of the multi-organ networks in the human body. To help illustrate the interconnections between the physiological concepts, principles and clinical presentations, it outlines clinical examples such as pathologies that link basic science with clinical practice in special “clinical correlates” sections. Covering both traditional and contemporary topics, it is a valuable resource for biomedical students, as well as healthcare and scientific professionals.

Book excerpt: While reflux disease, achalasia, esophageal spasm, gastroparesis and IBS include some of the most common disorders in all disease categories, the understanding of their pathophysiology has remained elusive. The field of clinical gastrointestinal motility has for decades relied on the measurement of intestinal movements for diagnosis and management of these difficult and enigmatic disorders of gut function. Although computers have increased the speed with which we can measure the movements of the gut, the devices to measure this movement have not changed in over 20 years. In the last 2 years, a new technologic breakthrough has taken place in the measurement of intestinal movement. The technology is called high resolution manometry. Rather than the old 4 and 8 channels systems of measuring pressure, high resolution employs 36 closely spaced solid state pressure transducers. By using this technology, the resolution of gut motor activity is incredible. This allows for better ways of viewing motility using color as pressure. This technology makes for beautiful images of gut motility that we have never seen before. We have made diagnoses that would never have been appreciated with the old technology. High resolution manometry is taking over conventional manometry worldwide and represents a dramatic leap in a long time stagnant area.

Available in PDF, EPUB and Kindle. Book excerpt: This book is a clinical manual that covers the whole spectrum of swallowing and its disorders. It starts with physiology of swallowing, pathophysiology of disordered deglutition, diagnostic methods (clinical and instrumental) and ends with an in-depth’s and up-to-date presentation of current treatment options. The clinically most relevant topics of dysphagia management on the stroke unit and the intensive care unit are dealt with in separate chapters. Also the closely intertwined issue of nutritional management is specifically addressed. Most importantly, the book covers all obligatory topics of the Flexible Endoscopic Evaluation of Swallowing (FEES)-curriculum, an educational initiative that started in Germany in 2014 and is currently being extended to other European and non-European countries. The book is richly illustrated and an online video section provides a number of typical patient cases. FEES is probably the most commonly chosen method for the objective assessment of swallowing and its disorders. It is used in stroke units, intensive care facilities, geriatric wards but also in rehabilitation clinics and within dedicated outpatient services. This book on neurogenic dysphagia therefore addresses a wide range of different medical disciplines, such as neurologists, geriatricians, intensive care physicians, rehabilitation physicians, gastroenterologists, otolaryngologists, phoniatrists and also speech-language pathologists.

Available in PDF, EPUB and Kindle. Book excerpt: This volume reviews the most recent knowledge in the field of gastrointestinal motility in health and disease. The topics addressed include basic as well as clinical data concerning the motor functions of the entire gut: the lower oesophageal sphincter and the gastro-oesophageal reflux; the gastric emptying and the role of the pylorus; the motility of the biliary tract and its disorders; the cyclic motor activity of the gut and intestinal transit; the colonic and ano-rectal motility. There are also impOltant contributions in physiology and pharmacology relating to the neurohumoral regulation of the gut, and the function of digestive smooth muscle. Several papers explore the nature of the linkage between brain and gut. a link which has long been deduced by clinicians but not, until recently, systematically explored by scientists. The individual papers, selected from a large number of submissions, have been subject to 'peer-review' by an inter national committee which includes both cliniCians and basic scientists. Therefore this book should serve as an up to date source of information for researchers concerned with basic sciences as well as for clinicians in gastroenterology, medicine and surgery. C. Roman v This volume is dedicated to the memory of two friends and colleagues: Professor Dr J. HELLEMANS Professor Dr H. MONGES Acknowledgments This was the 9th of this series of symposia held alternatively in Europe and North America, and the first to be held in France.

Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this volume is to serve as a useful, up-to-date reference manual and guide for the diagnostic and therapeutic approaches to common adult and pediatric gastrointestinal motility problems. In order to enhance the understanding of these disorders, a problem-oriented approach has been chosen, and whenever possible the authors have provided clinical case scenarios to illustrate their message. Gastrointestinal Motility has evolved from an esoteric laboratory tool to a sophisticated diagnostic technique that is now widely used clinically to guide 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'. With the growing knowledge and understanding of how gastrointestinal muscle and nerve dysfunction can cause disease, we are at the threshold of a revolution in our approach to the diagnosis and treatmentof gastrointestinal motility disorders. Practitioners and trainees in gastroenterology, radiologists, internists, family practitioners, as well as general surgeons, each of whom encounter patients with motility problems on a daily basis, will find this volume of use. The authors, experts in the field, have provided a succinct, practical, and balanced approach that can be used in any laboratory.
