Abstract
The report of colonofiberscopic therapy using a microwave coagulator is relatively rare. Recently, we epxperienced colonofiberscopic microwave coagulation therapy for a polypectomy, hemostasis and tumor reduction. We could perform this therapy in 12 cases using by endoscopic microwave probe, ball type and rod type. The complication of this therapy was free. It is presumed that this procedure is useful and recommendable for colonofiberscopic treatment.
