CRITÈRES D'EXCLUSION	(EN) Rectal adenocarcinoma (defined as tumour below the peritoneal reflection on imaging or within 15 cm of the anal verge by rigid sigmoidoscopy) Carcinoma only present in a completely excised polyp (i.e. no residual tumour evident in the colon) Prior VTE including deep vein thrombosis (DVT) or pulmonary embolism (PE) Requirement for full dose peri-operative anticoagulation Contraindication to heparin therapy history of heparin induced thrombocytopenia (HIT) platelet count of less than 100 x 109/L actively bleeding severe hypertension (SBP >200 and/or DBP >120) on more than one reading documented peptic ulcer within 6 weeks severe hepatic failure (INR >1.8) creatinine clearance of < 30 ml/min as calculated by the Cockcroft-Gault formula heparin or pork allergy Other contraindication to anticoagulation Geographic inaccessibility (less likely to comply with required follow-up visits and care) Participating in another interventional trial that may result in co-intervention or contamination (to be determined by sponsor) History of other malignancies (except for adequately treated basal or squamous cell carcinoma or carcinoma in situ) within 5 years of the colorectal cancer diagnosis Treatment, including radiation therapy, chemotherapy or targeted therapy, administered for the currently diagnosed colon cancer prior to randomization Pregnant or lactating Unable/unwilling to providing informed consent.
