Upper gastrointestinal (UGI) surgery is a fascinating field of medicine and surgery due to the complexity of the physiology and anatomy of the organ systems involved in multiple disease processes. Medical and surgical consultants are often involved in the case of patients with UGI

disorders in a collaborative and multidisciplinary environment that contributes to improved

patient care. This book, entitled Upper Gastrointestinal Surgery - Contemporary Techniques and Training, illustrates some of the most common diseases and challenges that clinicians and

specialists must diagnose and treat to help their patients after extensive training and with the collective experience that arises from a team approach. Such diseases and disorders that are presented in this book are discussed within well-developed chapters dedicated to metabolic and

bariatric surgery, hepatobiliary and pancreatic surgery, gastric surgical oncology, and

therapeutic endoscopy, to name a few, in addition to surgical simulation and education. Such chapters present state-of-the-art management algorithms and surgical techniques, including robotics, therapeutic endoscopy, and artificial intelligence as an adjunct to human judgment.

Surgical education and simulation are of paramount importance for disseminating safe surgical principles in a controlled and safe environment. In such a system, repetition, precision, attention to detail and self-improvement are emphasized and promoted for the benefit of the patient.
