[ERAS: perioperative care for the benefit of the patient].

During surgical procedures, surgery, and anesthesia lead to pathophysiological stress on the human body. The goal of perioperative medicine is to prepare patients and take all possible measures to reduce this pathophysiological stress. The emergence of ERAS over the past 15 years has made it possible to set up a multimodal program based on scientific evidence, showing that the adequate application of an improved rehabilitation program after surgery, ERAS-type, is possible in all surgical specialties, including gynecology, cardiac surgery, and neurosurgery. ERAS improves the quality of life of patients, reduces postoperative complications and lengths of stay, and finally, reduces costs. The purpose of this article is to show the most important elements of such an ERAS program by taking the example of digestive surgery.
