Worldwide, more than 20 million patients undergo groin hernia repair annually. In order to standardize care, minimize complications, and improve results, five continental hernia societies (European Hernia Society, Americas Hernia Society, Asia Pacific Hernia Society, Afro Middle East Hernia Society, and Australasian Hernia Society), the International Endo Hernia Society and the European Association for Endoscopic Surgery have jointly released the International guidelines for groin hernia management (2018). Here, the authors interpret the day surgery section of the guidelines in detail.
