TREATMENT OF RECTAL AND RECTOSIGMOID CANCER COMPLICATED BY TUMOR BLEEDING USING THE METHOD OF X-RAY-ENDOVASCULAR HEMOSTASIS

Abstract

Short-term treatment outcomes of X-ray endovascular hemostasis in patients with rectosigmoid and rectal cancer complicated by bleeding were presented. Patients were divided into two groups. Group I (study group) consisted of 16 patients who underwent x-ray-endovascular hemostasis. Group II (control group) included 17 patients who received conservative methods of hemostasis. After hemostasis, patients with rectal cancer from both groups received preoperative radiotherapy followed by radical surgery. Patients with rectosigmoid cancer underwent surgery alone. The components derived from donated blood were used in a significantly larger volume in patients from the control group than in patients from the study group (p<0.01), with the same median estimated blood loss. Recurrence of bleeding was observed on 13.3 ± 1.6 days in 100 % of control group patients. There was no evidence of bleeding recurrence in the study group patients. The relative risk reduction of bleeding was 100 % in Group I patients. Thus, the method of X-ray-endovascular hemostasis allows intraluminal tumor bleeding completely to be stopped avoiding repeated blood transfusions.
