Patients and Methods: We compared the clinicopathological characteristics of octogenarians who underwent surgery for colorectal cancer before the establishment of PERIO intervention (Control group) with those who received prehabilitation (PERIO group). All patients were classified as American Society of Anesthesiologists (ASA) class 3 or higher. The primary outcome was the incidence of postoperative complications. Results: There were 21 patients in the Control group and 19 patients in the PERIO group. Operative time was significantly longer in the PERIO group (Control group, 200 min vs. PERIO group, 230 min; p=0.03) and blood loss was significantly higher in the PERIO group (Control group, 5 ml vs. PERIO group, 30 ml; p=0.02). Postoperative complications occurred in 10 patients (47.6%) in the Control group and 3 patients (15.8%) in the PERIO group and were significantly lower in the PERIO group (p=0.03). Postoperative hospital stay was 13 days (range=7-31 days) in the Control group and 11 days (range=8-70 days) in the PERIO group (p=0.39). The rate of discharge directly to home was 81% in the Control group and 93.3% in the PERIO group (p=0.29). Conclusion: In frail octogenarians with colorectal cancer of ASA class 3 or higher, the incidence of postoperative complications was significantly lower after PERIO intervention.
