The aim of this study was to investigate the short-term outcomes of surgery for colorectal cancer(CRC)in the elderly aged over 90 years old. We retrospectively analyzed 1,043 patients with stage Ⅰ-Ⅳ CRC who underwent curative surgery in our institutions between 2013 and 2022. The patients were divided into the super older(aged ≥90 years, 20 patients) and non-super older groups(aged 80-89 years, 243 patients). The short-term outcomes were compared between the 2 groups. There were no significant differences in tumor location, stage, surgical approach, duration of operation and blood loss. The incidence of severe postoperative complications did not differ between the 2 groups. In conclusion, our study suggested that surgery for colorectal cancer could be as safely performed in super elderly patients as in non-super elderly patients.
