Purpose: The right colon tumor manifests itself more with bleeding and associated symptoms. Accordingly, the outcome of anemia is more common than the tumors settled in the other areas of the colon. In this study we aimed to study the effect of tumor placement on the need for blood transfusion in colon tumor patients operated in our clinic. Tools and Methods: 192 patients who were operated due to colon tumor were taken to the study between November 2007 and February 2013. Patients were studied in two groups: the right colon (Group A=94) and the left colon (Group B=98) tumors. These patients’ demographic data, operational procedures, preoperative and postoperative hemoglobin (HGB) values, erythrosite suspension (ES) transfusion needs, complications and mortality results were studied. Results: There was no difference between the two groups in terms of demographic data. Preoperative Hgb values were also significantly low in Group A (medium 10.9±2 mg/dL to 11.6±2 mg/dL, p=0.031). The preoperative ES transfusion rate was significantly high in Group A (19% to 8%, p=0.034). The amount of ES transfusion was statistically high with an average of 0.56 units in Group A (Group B: 0.23, p= 0.038). But the overall ES transfusion ratio was not significant between the 2 groups (62% to 47, p=0.06). There was no difference between the two groups when compared the values of hospitalization, postoperative complications (18% to 17%) and mortality (2% to 5). In patients with right and left colon tumors, mortality was not associated with ES application (p=0.515). The result: Preoperative Hgb values were found lower in patients with the right colon tumor than in patients with the left colon tumor. This is also associated with increased preoperative ES transfusion in these patients. There is no increase in postoperative morbidity and mortality. We believe that more transfusion in the right colon tumors according to our results does not cause more morbidity and mortality than the left colon tumors.
