Postoperative complications and emergency surgeries in colorectal cancer patients <50 years-a national cohort study.

Colorectal cancer patients <50 years and 50-79 years had a higher proportion of surgical complications regarding anastomotic leakage, intra-abdominal infections and wound infections but lower overall postoperative complications. The incidence of surgical emergencies was highest amongst patients ≥80 years. Postoperative diagnostic workup in symptomatic individuals <50 years is warranted.
