Book excerpt: Over the last quarter of a century, the fields of medical ethics and of legal issues related to medical practice have rapidly developed for a number of reasons. Firstly, the provision of healthcare nowadays is based on a complicated partnership between healthcare providers, patients, administrators and organizations responsible for providing finance; this complicated partnership frequently results in clashes of views, opinions, and priorities, which have a major ethical and legal dimension. Secondly, a major event of the 21st century is the development of multicultural societies; healthcare-related decisions thus have to be made on the background of so many different ethnicities, religions, cultures and languages, resulting in a great spectrum of ethical and legal implications. Thirdly, in the modern world, people are more mobile and can easily and cost-effectively seek treatment outside of their country of origin or residence, which raises many ethical and legal issues. Lastly, the development of new medical specialties, modern and advanced treatments for very challenging patients, and the introduction of new technologies in medical practice have dramatically broadened the spectrum of ethical and legal issues related to medical practice. This book will therefore aim to cover in detail general principles and specific issues related to the ethical and legal dimensions of modern surgical practice.
