The Tenth Edition of Schwartz’s Principles of Surgerymaintains the book’s unmatched coverage of the foundations of surgery while bringing into sharper focus new and emerging technologies. We have entered a new era of surgery in which minimally invasive surgery, robotic surgery, and the use of computers and genomic information have improved the outcomes and quality of life for patients. With these advances in mind, all chapters have been updated with an emphasis on evidence-based, state-of-the-art surgical care. An exciting new chapter, “Fundamental Principles of Leadership Training in Surgery,” expands the scope of the book beyond the operating room to encompass the actual development of surgeons. This edition is also enriched by an increased number of international chapter authors and a new chapter on Global Surgery. More than ever, Schwartz’s Principles of Surgery is international in scope–a compendium of the knowledge and technique of the world’s leading surgeons.
