Read our Colorectal Cancer research guide →This is an observational study—meaning researchers will watch and track what naturally happens—involving patients who have had colorectal cancer surgery. All participants receive , a low molecular weight heparin medication to prevent dangerous blood clots after surgery. The study compares two groups: those who start the medication within 24 hours of surgery versus those who start it after 24 hours, to understand which timing is safest and most effective.
Blood clots in the legs are a serious risk after cancer surgery, but doctors aren't certain about the best time to start prevention medication—too early might cause bleeding, while too late might allow clots to form. This study will help doctors decide when to begin this treatment to give patients the best protection.

After your colorectal cancer surgery, you will receive daily injections of the prevention medication under your skin for as long as you stay in the hospital (usually 7–10 days). You will have an ultrasound of your legs before you leave the hospital and again 28 days after surgery to check for blood clots. Researchers will track which timing group you naturally fall into based on your surgery time, and follow your health for the full 28 days.
