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.

Book Description
This casebook provides a concise yet comprehensive state-of-the art review of common stomach and small intestine disorders. The casebook is divided into five parts, each of which focuses on a major disorder, symptom, or clinical scenario related to the stomach and small intestine, including dyspepsia, small bowel disorders, nausea and vomiting, chronic abdominal pain, and post-operative GI surgery challenges. Each part is comprised of cases illustrating different aspects of the subject, with each case containing sections on case presentation, objectives, epidemiology and etiology, diagnostic evaluation and treatment, case follow-up, clinical pearls, and Q&A. Some major topics presented in these cases include nausea and vomiting in the pregnant patient, gas-bloat, functional abdominal pain, post-GI surgery complications, and celiac disease and non-celiac gluten sensitivity. Written by internationally renowned experts in the field, Essential Medical Disorders of the Stomach and Small Intestine: A Clinical Casebook is a valuable resource for clinicians and practitioners who treat patients afflicted with disorders of the stomach and small intestine.

Book Description
This is the second, updated and extended edition of a well-received book that offers a comprehensive overview of ultrasonographic imaging of acute and chronic gastrointestinal diseases, including acute abdomen, appendicitis, diverticulitis, inflammatory bowel diseases, neoplasms and masses, infections, malabsorption syndromes, and rare conditions. The value of ultrasound in each disorder is clearly explained and illustrated, and limitations identified. Information is also provided on recent technical developments and ultrasound applications that are likely to become of increasing importance, such as functional and 3D ultrasound, contrast agents and intraoperative ultrasound, elastography, and transperineal ultrasound. The authors are all distinguished experts in the topics they address. Ultrasound of the Gastrointestinal Tract will be a helpful guide in daily practice not only for radiologists but also for gastroenterologists, abdominal surgeons, pediatricians, and oncologists.

Book Description
Gastrointestinal (GI) physiology is a fundamental subject that is indispensable not only for undergraduate but also for graduate courses. The audience include, but are not limited to, medical, pharmacy, nursing, human biology, Chinese medicine, and science students, as well as other health-related subject students. The overall objectives of this textbook are to present basic concepts and principles of GI physiology and, more importantly, to convey an understanding of how to apply this knowledge to abnormal GI physiology in the clinical context. As such, the basic knowledge of GI physiology and its application in the form of clinical case studies should be grasped, which are critical for professional examinations and bedside, as well as for general practice in the future. In this handbook, we aim to achieve these elements by covering the breadth of GI, pancreatic, hepatobiliary, and nutritional physiology. Moreover, we include relevant scenario-based clinical case in each chapter so as to evaluate whether the students can apply the basic GI they learn to the clinical setting.

Book Description
AN INSTANT NEW YORK TIMES BESTSELLER “Everything you ever wanted to know about the gut (and then some).” —SELF Discover the secrets of your digestive system—and how to hone a healthy gut—plus new research on the mind-gut connection. With quirky charm, science star and medical doctor Giulia Enders explains the gut’s magic, answering questions like: What’s really up with gluten and lactose intolerance? How does the gut affect obesity? What's the connection between our microbiome and mental health? Why does acid reflux happen? In this revised edition of her beloved bestseller, Enders includes a new section on the brain-gut connection, and dives into groundbreaking discoveries of psychobiotics—microbes with psychological effects that can influence mental health conditions like depression and even stress. For too long, the gut has been the body’s most ignored and least appreciated organ. But it does more than just dirty work; it’s at the core of who we are, and this beguiling book will make you finally listen to those butterflies in your stomach: they’re trying to tell you something important.

Book Description
On July 9-10, 2014, the Institute of Medicine's Food Forum hosted a public workshop to explore emerging and rapidly developing research on relationships among the brain, the digestive system, and eating behavior. Drawing on expertise from the fields of nutrition and food science, animal and human physiology and behavior, and psychology and psychiatry as well as related fields, the purpose of the workshop was to (1) review current knowledge on the relationship between the brain and eating behavior, explore the interaction between the brain and the digestive system, and consider what is known about the brain's role in eating patterns and consumer choice; (2) evaluate current methods used to determine the impact of food on brain activity and eating behavior; and (3) identify gaps in knowledge and articulate a theoretical framework for future research. Relationships among the Brain, the Digestive System, and Eating Behavior summarizes the presentations and discussion of the workshop.
