Learning about specific diseases that are usually treated with surgery, as well as understanding the principles of managing surgical patients, is integral to the medical curriculum and an essential precursor to the study of operative surgery. The new 4th edition of Principles and Practice of Surgery presents a systematic approach to these key topics and familiarises students with surgical processes and protocols. This disease-based textbook is a surgical companion to the renowned Davidson's Principles and Practice of Medicine, and is edited by an entirely new team of respected authorities in the field. Written as a complete, balanced text, it enables the reader to appreciate both the medical and surgical implications of diseases encountered on surgical wards.
