Abstract
Background and aim:The advantages of the conventional bipolar snare are less opportunity of perforation and heat damage to specimens. But, the disadvantage of the conventionalbipolar snare is easy to bleed at the part of the ceramic insulator. On the sheath type bipolarsnare(B-wave), the wire side has only negative electrodes without ceramic insulator and thesheath side has positive electrode. For this reason, it was reported that B-wave had lessopportunity for bleeding compared with the conventional type. High frequency surgery unit(Erbotom ICC200, ERBE)has an automatic controller for current altered by the impedance ofspecimens by monitoring the cutting condition. Thus, we attempted to analyze the combinationtrial with B-WAVE and Erbotom ICC200 to reduce hemorrhage on polypectomy or EMR ofcolon polyps with the basic examination. Materials and methods:Sixty four patients with 100 polyps lesions were enrolled. Thesepatients were separated in two groups using ERBE and an ordinary blending current unit(Blend). EMR of colon polyps was practically done. Hemorrhage after EMR or polypectomywas analyzed. Result:We recognized 5 cases of hemorrhage in Blend group. Whereas only one case ofoozing in ERBE group. Conclusion:The combination with B-WAVE and ERBE is able to reduce a risk of hemor-rhage on polypectomy and EMR and it will provide more safe and effective resection of colonpolyps by using the bipolar snare.
