title: [Coagulation disorder and its uncommon complication in a patient with obturating sigmoid carcinoma].
abstract: OBJECTIVE
  The authors point to the risk of hypocoagulation by patients with colorectal carcinoma, who use warfarin.
  
  
  METHODS
  185 patients with colorectal cancer were examined for plattellets, prothrombin time and D-dimer.
  
  
  RESULTS
  Only 64 patients (35%) had haemocoagulation in the standard, 114 patients (61%) were hypercoagulable and only 7 patients (3.7%) were hypocoagulable. The authors present an interesting case report of a patient who used warfarin. This patient has ileos state by sigmoideal cancer, and in parallel a progressive intramural haematoma in the hepatic flexure of the colon.
  
  
  CONCLUSIONS
  Hypocoagulation state with an intramural haematoma of colon may be very dangerous complication for patients with colorectal cancer and ileos state. Very careful choice of surgical strategy is necessary.
