Day surgery for inguinal hernia Hernia surgery has experienced a very positive development in the past 30 years: better meshes, better understanding of the anatomy and the nerves, improved skills-training, minimally invasive and more precise operations (e. g. also with the robot), just to name a few. This directly results in fewer recurrences, less chronic pain and better quality of life. In the current article, the growing importance day-care surgery of inguinal hernias is discussed – not least because of the statutory AVOS regulation that came into effect in Switzerland on 01.01.2019. This article reviews the indication and the most important surgical procedures for day-care groin hernia repair. There is no single standard procedure (no one-fits-all), since according to today's knowledge every patient is an individual case and must have access to an individually tailored procedure. For day-surgery inguinal hernia repair with mesh, both conventional and minimally invasive procedures are suitable. When planning outpatient hernia repairs, it must also be taken into account that acute postoperative pain is of negative prognostic significance, which is why optimal postoperative pain therapy should be well coordinated with the general practitioner in the first days after the operation. With all the positive aspects of AVOS, it is still not clear how the further training of the young generation will take place under the current conditions, as it is no longer provided for in the structural and reimbursement regulations. There is an urgent need for improvement here.
