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.

Download The Esophagus Book in PDF, ePub and Kindle
THE ESOPHAGUS The Esophagus investigates the anatomy, physiology, and pathology of the esophagus. This sixth edition, revised and updated throughout, also explores the diagnosis and treatment of various esophageal conditions. It includes treatment guidelines approved by the two largest gastroenterology societies, the ACG and AGA, as befits a work co-edited by two former presidents of those organizations. Advancements in diagnostics are presented, as are developments in the surgical and drug therapies. Presented in full colour, and boasting an unrivalled team of editors and contributing authors, The Esophagus Sixth Edition will find a home wherever the anatomy, physiology, and pathology of the esophagus are studied and taught. This book is accompanied by a website containing all the figures from the book in PowerPoint format. www.wiley.com/go/richter/esophagus6e Praise for the Fifth Edition: “There is absolutely no doubt that this edition of the textbook will maintain its status as the go-to reference for esophageal conditions, and will remain a highly utilized and clinically useful resource for novice and experienced physicians and surgeons alike.” (Gastroenterology, 1 July 2013)

Download Neurogenic Dysphagia Book in PDF, ePub and Kindle
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.

Download Gastrointestinal Physiology Book in PDF, ePub and Kindle
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.

Download A Guide to Gastrointestinal Motility Disorders Book in PDF, ePub and Kindle
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.

Download Laryngopharyngeal and Gastroesophageal Reflux Book in PDF, ePub and Kindle
This text comprehensively reviews the current state of the art in Laryngopharyngeal Reflux (LPR) together with a comprehensive explanation and description of the known gastroesophageal reflux (GERD) literature. With chapters written by experts from around the world, this text aims to deliver what is current in reflux recognition, diagnosis, reflux related complications, and the various treatment modalities. This is the first textbook to combine the most up to date knowledge of both LPR and GERD meant for both specialties and the general medicine population. Completely unique to the reflux literature is a section detailing the substantial benefits of a mostly plant based, Mediterranean style diet in the treatment of reflux disease. Encouraging patients to read and learn about diet and health is likely the most important step in improving their disease. The text provides direction to the caregiver on how to transition to a mostly plant-based diet. Review of myths, effects of diet in the setting of other disease states, and dietary consequences are explained. Guidelines on how to transition diet, dining out while maintaining a plant-based diet, and how to wean off medication, such as PPI, are also provided. Laryngopharyngeal and Gastroesophageal Reflux: A Comprehensive Guide to Diagnosis Treatment, and Diet-Based Approaches will provide the medical community with a resource to understand, teach, and provide the latest in LPR and GERD information to the caregiver and subsequently the patient.
