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)
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.

Human life relies on two basic supplies, oxygen and food. Oxygen can be utilized directly, but food has to go through a long process of digestion to become usable nutrients. The esophagus is the beginning part of this long journey. Because of its critical location, any abnormalities in this part of the body can be devastating and life-threatening and difficult to treat. This book covers many aspects of esophageal disorders, from congenital diseases to cancer. It includes 11 chapters written by highly experienced scholars from all over the world. It is our intention to provide readers an update in esophageal study and to raise the awareness how important this organ to our entire body system.
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.
Esophageal anomalies and disorders in infancy and childhood include a wide spectrum of different diseases. These range from emergencies immediately after birth such as esophageal atresia (EA), necessitating an experienced team of neonatologists and pediatric surgeons, up to gastro-esophageal reflux disease in elder children, necessitating the pediatric gastroenterologist and visceral surgeon. In the last few years some fascinating pediatric surgical techniques have evolved, such as the thoracoscopic correction of EA or the FOKER technique for elongation in cases of long-gap, EA. Prof. Foker has developed this special traction technique and is the world's leading expert in long-gap EA.

This book provides teaching scripts for medical educators in internal medicine and coaches them in creating their own teaching scripts. Every year, thousands of attending internists are asked to train the next generation of physicians to master a growing body of knowledge. Formal teaching time has become increasingly limited due to rising clinical workload, medical documentation requirements, duty hour restrictions, and other time pressures. In addition, today’s physicians-in-training expect teaching sessions that deliver focused, evidence-based content that is integrated into clinical workflow. In keeping with both time pressures and trainee expectations, academic internists must be prepared to effectively and efficiently teach important diagnostic and management concepts. A teaching script is a methodical and structured plan that aids in effective teaching. The teaching scripts in this book anticipate learners’ misconceptions, highlight a limited number of teaching points, provide evidence to support the teaching points, use strategies to engage the learners, and provide a cognitive scaffold for teaching the topic that the teacher can refine over time. All divisions of internal medicine (e.g. cardiology, rheumatology, and gastroenterology) are covered and a section on undifferentiated symptom-based presentations (e.g. fatigue, fever, and unintentional weight loss) is included. This book provides well-constructed teaching scripts for commonly encountered clinical scenarios, is authored by experienced academic internists and allows the reader to either implement them directly or modify them for their own use. Each teaching script is designed to be taught in 10-15 minutes, but can be easily adjusted by the reader for longer or shorter talks. Teaching Scripts in Internal Medicine is an ideal tool for internal medicine attending physicians and trainees, as well as physician’s assistants, nurse practitioners, and all others who teach and learn internal medicine.
