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
Anorectal Disorders: Diagnosis and Nonsurgical Treatments incorporates the most recent major advances in the understanding of anal and rectal anatomy to provide clinical evidence of care for those suffering from anorectal disorders. By condensing basic and practical aspects in the knowledge of anorectal disorders, this book provides a comprehensive review of the anatomy and physiology of the anorectal region. It includes new technology that expands and modifies current perceptions about the functional anatomy of the anorectal region and ultimately impacts how we conceive muscle and nerve structures functioning together to maintain fecal continence and properly execute the process of defecation. Perfect for medical researchers, gastroenterologists, general practitioners, internal medicine doctors and general surgeons, this title will provide diagnosis and treatment options for all patients suffering from anorectal disorders. - Identifies frequent, but not well understood, anorectal disorders, including ulcers, constipation, dyssynergic defecation, tumors and malformations - Condenses the basic and practical aspects of anorectal disorders for better treatment of patients - Includes clinical cases that summarize chapter content in a clinical context

Book Description
This is the first volume in the new Springer Major Reference Work series entitled Coloproctology. The book covers key topics in the anatomy and physiology of the colon, rectum and anus and the diagnosis of colorectal/anal diseases and disorders. It thus forms a sound basis for further volumes in the series that will focus on the treatment of more specific clinical conditions. The subjects addressed in the volume are crucial to effective patient management and the book highlights the fact that adequate diagnostic assessment of a given disease is significantly related to the pathophysiologic interpretation of the pathologic process. The purpose of the volume is to provide readers with up-to-date knowledge on colorectal and anal anatomy and physiology, particularly from a treatment perspective and to describe the methodology to be employed in choosing the best diagnostic work-up in coloproctology.

Book Description
This third edition text provides a completely revised and updated new version of this unique, modern, practical text that covers the strategic evaluation, specific approaches, and detailed management techniques utilized by expert colorectal surgeons caring for patients with complex problems–whether they result from underlying colorectal disease or from complications arising from previous surgical therapy. The format follows that of both a “how to” manual as well as an algorithm-based guide to allow the reader to understand the thought process behind the proposed treatment strategy. By making use of evidence-based recommendations, each chapter includes not only background information and diagnostic/therapeutic guidelines, but also provides a narrative by the author on his/her operative technical details and perioperative “tips and tricks” that they utilize in the management of these complex surgical challenges. Distinctive to this book, is the reliance on experts in the field including past presidents of the ASCRS, as well as multiple other national and internationally recognized surgeons, to lend their personal insight into situations where data may be more sparse, but individual and collective experience is paramount to making sound decisions and thereby optimizing patient outcomes. The text includes chapters on the assessment of risk and methods utilized to minimize perioperative complications. In addition, it incorporates sections covering the medical and surgical therapies for abdominal, pelvic and anorectal disease. Moreover, the technical challenges of managing complications resulting from the original or subsequent operations is addressed. The underlying focus throughout the text is on providing pragmatic and understandable solutions that can be readily implemented by surgeons of varying experience to successfully treat complex colorectal problems. However, it also goes beyond the technical aspects of colorectal surgery and includes special sections highlighting the essence of a surgeon; covering aspects involving the medical-legal, ethical, and economic challenges confronting surgeons. Throughout the text, each author provides an ongoing narrative of his/her individual surgical techniques along with illustrations and diagrams to “personally” take the reader through the crucial steps of the procedure, and key points of patient care inherent to that topic. Additionally, where appropriate, links to online videos give the reader an up-front look into technical aspects of colorectal surgery.
