The aim of this book is to focus on the clinics in bariatric and metabolic surgery. Bariatric surgery has evolved to be the most effective method of treatment for morbid obesity. With obesity and metabolic diseases on the rise, more and more surgeons are now needed to addressing this concern. The book is divided into three well-written sections following as History, Care Capsules followed by detailed discussions of a topic, and surgical techniques, which is further divided into 32 chapters. The book is comprehensive and can be read as a textbook in the field. The reader can also use the book to answer questions and review a perspective approach to a specific problem. For some, this book may serve as the starting point for innovative thought, for the elucidation of the mechanisms of action of metabolic bariatric surgery and, perhaps, to consider the etiology of the malignant diseases we are treating. The book persuasively provides these essential elements and will serve as a frequently consulted source of information.
