Abstract
Malnutrition remains a significant yet underrecognized predictor of poor postoperative outcomes in colorectal surgery. This retrospective study analyzed the association between preoperative nutritional status and postoperative recovery in 132 patients undergoing colorectal procedures. Malnourished individuals demonstrated higher rates of surgical site infections, prolonged hospitalization, and delayed wound healing compared with well-nourished patients. Nutritional screening identified 38% of patients at moderate to high risk preoperatively, and mortality was notably greater in this group. These findings underscore the importance of optimizing nutritional status before surgery to improve outcomes and reduce postoperative complications.
