Intraoperative complications will be graded according to the ClassIntra classification of intraoperative adverse events. The quality of postoperative recovery of each observed patient will be scored on the first, second and fifth postoperative day, using the 15-item quality of recovery scale (QoR-15).~Data about red blood cell transfusion rate, all-cause infection rate, number of days when antibiotics were administered and the number of different antibiotics administered during hospital-stay will be collected."
