Predictors of perioperative morbidity in elderly patients undergoing colorectal cancer resection

Aim Colorectal cancer resection in the elderly may be associated with significant morbidity. This study aimed to assess perioperative morbidity in elderly patients undergoing colorectal cancer resection and to investigate risk factors for postoperative complications. Materials and Methods Consecutive patients aged ≥ 75 years undergoing colorectal cancer resection with curative intent between January 2014 and December 2021 at our institution were included. We evaluated risk factors for postoperative complications, length of hospital stays (LOS), 30-day readmission, and 90-day mortality rates. Results A total of 843 patients underwent colorectal cancer resection during the study period, of whom 202 patients were 75 years or older. Advanced age was associated with postoperative complications (Clavien–Dindo score > 3b, p = 0.001). Sarcopenia, preoperative plasma albumin
