Purpose of review Improvements in perioperative care contributed to enlarge the eligibility criteria for day case surgery and more and more patients with comorbidities may be concerned. However, underlying medical diseases may influence postoperative outcomes, and therefore, must be considered when selecting patients to undergo ambulatory surgery. Recent findings To limit postoperative complications, rigid patient selection criteria are often applied in ambulatory surgery. In practice, however, most of these criteria predict the occurrence of treatable perioperative adverse events but not the need for unanticipated admission or readmission. Summary The underlying medical diseases should not be considered as sole criteria but they should rather be regarded as a dynamic process, which includes the surgical procedure as well as the experience and expertise of the perioperative setting.
