Values denote median values (inter-quartile range) or n (%) of patients if nothing else was stated. Continuous variables were analysed by t-test if normally distributed, or by Mann–Whitney U-test if not normally distributed. Categorical variables were analysed by χ2 or Fisher's exact test when appropriate. Surgery converted from MIS to OS is not included in analysis of LOS for OS or MIS procedures. LOS, length of stay; MIS, minimal invasive surgery; OME, oral morphine equivalent; OS, open surgery; PO, per os; POD, postoperative day; RIOT, return to intended oncologic therapy; sd, standard deviation.
