An Illustrated Guide to Gastrointestinal Motility Edited by Devinder Kumar Surgical and Gastrointestinal Science Research Unit, London Hospital Medical College, London and Sven Gustavsson Department of Surgery, University Hospital, Uppsala, Sweden Diagnostic and research techniques for the study of gastrointestinal motility have grown substantially over the last few decades, both in number and complexity. This book brings together a wide range of expertise on what has become a highly specialized and differentiated area of gastroenterology, to provide a complete practical guide to the study and clinical management of the problems presented by gastrointestinal motility disorders. The advantages and disadvantages of all available techniques are compared and further clarification is offered by numerous diagrams, photographs and tracings. The motor physiology of the oesophagus, stomach, duodenum, biliary tree, small and large intestine, anorectum and sphincteric regions are discussed individually; their normal ranges of motility are established and potential abnormalities are evaluated as primary or secondary clinical conditions. In addition the effects on motility of the different pharmacological agents are identified, as are the problems associated with psychological stress and postsurgical states. For research and practising gastroenterologists and all clinicians this book will improve the understanding, diagnosis and treatment of those patients suffering from gastrointestinal motility disorders.
