The great progress in gastrofiberscopy has brought us a broadening of its application to both diagnosis and treatment. We have performed 33-polypectomies in 32 cases, utilizing radio frequency electric current under visual control with gastrofiberscope. We discussed the safety of this method and perfect retrieve of the resected polyps. Out of the 3 electrodes, i.e., the one with blunt tip, the one with goblet-shaped forceps and the coagulation electrode with loopwire, that were all invented by us, the last one is superior to the others in its quality. The adhesion method by suction with GIF-D has improved the ratio of the retrieve of the polyps. We have experienced a case that awakened us to the new significance of biopsy in toto by endoscopic polypectomy. In this case, the biopsy before polypectomy showed atypical cells of group III but histological examination after endoscopic polypectomy revealed local nestle of adenocarcinoma papillotubulare.
