We studied about the effect of the detachable snare for patients with large pedunculated polyp of the colon. The materials were as follows : sixteen cases were applied for preventing hemorrhage, and the other for hemostasis after polypectomy on emergency. The size of the polyps were from 13mm to 30mm at the maximum diameter of their head (mean 19.8mm) . Seven cases were treated at out-patient ward and the others were treated in hospital. To strengthen the effect of the snare, we ligated the stalk of the polyp twice by the snare in one case, and in five cases, endoscopic hemo-clipping procedure was used in combination. No bleeding was found after polypectomy in every cases. In the case of emergent hemostasis, we could ligate the residual stalk easily by the snare and succeeded in arrest of bleeding.
We concluded that the detachable snare is very useful and safe instrument for preventing hemorrhage or hemostasis after polypectomy of pedunculated polyps especially with large and wide stalk.
