This book presents a practical and detailed overview of the surgical treatment of obesity and metabolic surgery. The individual surgical procedures, along with their specific indications, execution, and risks, are thoroughly described in both text and images. Special emphasis is placed on selecting the appropriate surgical procedure for each patient. In addition to the mechanisms of action underlying the surgical procedures and the preceding conservative therapy, the formal steps involved, surgical preparation, and postoperative care are explained. Both surgical and internal medicine as well as psychosomatic complications are discussed in detail. Information on the establishment and certification of an obesity center, along with a look at new developments in bariatric therapy, completes the volume.
