Variability in care in emergency surgery is well known, particularly in abdominal surgery, and reducing it is fundamental to improving outcomes. It is therefore vital to identify the factors that are key to improving mortality and reducing complications in various surgical emergencies. Under the leadership of the World Society of Emergency Surgery, over 200 leading experts in emergency surgery, critical care and surgical infections established a template to help define and optimise emergency surgery, particularly that relating to the abdomen. This book refines this initial work, crystallising it into a meaningful resource for practising surgeons and health care administrators alike, and paving the way for advances in emergency surgery around the globe. This book sets a benchmark for Emergency Surgery and is a must read for those wanting their patients to do better.
