HEMOSTATIC EFFECT OF PURE ETHANOL INJECTION THROUGH FIBEROPTIC COLONOSCOPE ON HEMORRHAGE AFTER POLYPECTOMY

Abstract

Hemostatic effect of pure ethanol injection under direct vision through an endoscope devised by Asaki et a1 on bleeding after colonoscopic polypectomy was evaluated. In two cases, prophylactic ethanol injection into a cut surface of the stalk was performed. In eight cases with oozy bleeding and one case with pulsatile bleeding, ethanol injection into the bleeding site achieved a satisfactory hemostasis without any complications. In one case with oozy bleeding, recurrent bleeding occured on the 10th and 14th days after initial ethanol injection at polypectomy. Emergency colonoscopic examination revealed the presence of oozy bleeding from the cut-site of the stalk. Prompt hemostasis was obtained after local injection of pure ethanol. Even in this case and another case of pulsatile bleeding, we could avoid blood transfusion or laparotomy owing to this hemostatic method. From the standpoint of simple maneuver, safety, reasonable cost and satisfactory efficacy, it was considered that this method was effective to stop bleeding from the cut surface of the stalk after colonoscopic polypectomy.
