Book Description
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.

Book Description
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)

Book Description
This text is organized by organ system and the illustrations highlight surgical pearls borne of experience and polished by the study of pertinent references. Hand-drawn and illustrated figures show exact anatomical relationships as we see them in-vivo. A question/answer format augments the images to allow the reader to actively reflect on the topic and to appraise his/her knowledge in that area. The discussion sections strive to explain not only what the correct answer is, but also why the distractors are wrong, in order to motivate discussion and self-reflection. Cognitive Pearls in General Surgery details the explicit thought processes and associations that underlie the understanding of the topics at hand, with the intent of enhancing the fun and enjoyment that only an informed and well-grounded practice of surgery can provide.

Book Description
The updated and expanded Second edition of the Atlas of Esophageal Diseases provides an 11-chapter visual panorama of the esophagus in both health and disease. More than 600 detailed images, including many hand-drawn illustrations, cover all aspects of the esophagus. The Atlas opens with a chapter on esophageal anatomy and physiology, and takes the reader through an exploration of gastroesophageal reflux disease, pH-monitoring, and finally, surgery of the esophagus.

Book Description
While a surgeon many decades agotreated diseases from headtotoe, this concept has evolved, and today some degree of specialization is the rule worldwide. In many countries various boards for sub-specializations are designed, and after a broad training in general surgery, many young surgeons move on further into a specific field. Knowledge of anatomy and precise surgical technique remain the foundation of high quality surgery. A knowledgeable surgeon, equipped with excellent theore- cal and clinical skills, will only be accomplished when he or she masters the - erative techniques of the practice of surgery. The legacy of an academic surgeon or a surgical teacher relies in great part onthe transmission of his or her surgical abilities. Significant influence on the development in esophageal surgery arises from the surgical understanding of the anatomical and functional structures of the esophagus as well as the ongoing developments in the multidisciplinary m- agement in this challenging field of surgery. In bringing forth this atlas, we were motivated by the desire to create a comp- hensive and educational atlas on esophageal diseases, emphasizing all details of pathophysiologies, diagnostic strategies, pre- and postoperative management, and operative techniques covering minimally invasive and open procedures ranging fromstraightforward tomore complex procedures.
