Patients with inflammatory bowel disease face significantly higher venous thromboembolism (VTE) risks post-colorectal cancer (CRC) surgery.

• 30-day VTE risk is 1.5% in IBD patients, compared to 0.7% in non-IBD patients (adjusted hazard ratio 1.61).
• The highest risks are in males (ahr 2.26), patients aged 60-69 (ahr 4.63), those who received prior IBD treatment (ahr 1.95), and with active disease (ahr 5.29).

Surgeons should optimize disease management and be vigilant for VTE in high-risk IBD patients undergoing CRC surgery.
