High frequency oscillators have been developed and utilized for endoscopic polypectomy. Animal experiments were performed before applying them clinical trials. The results obtained from animal experiments and the findings by clinical trials were reported.1. Among oscillators, a transistor type which can provide a regular wave seemed to be most suitable. One with a built-in timer as a safety device is preferable.2. Degree of changes in the mucous membranes caused by high frequency current were almost proportional to the intensity and time of flow of electric current, however they were inversely proportional to the size of the area of the mucous membrane where an electrode were attached.3. Pathological study showes that changes in the tissues induced by coagulating wave sometimes continued to proceed over 1-2 weeks. Therefore, while performing polypectomy it is desirable to try to leave a polyp root by 3-5 mm in length.4. The size of a postoperative ulceration and the days required for its healing were dependent upon the thickness of pedicle, the duration of current flowed, and the place where the snare was set.5. Postoperative bleeding sometimes occured in cases in which the polyp had been removed with incomplete coagulation.6. Endoscopic polypectomy could be a perfect biopsy method which can cover demerits of usual biopsy methods. Further histological studies on removed polyps could provide the in formation for the definitive treatment of malignant polyp.7. We believe that there would be no accidental complications with enough understandings of properties of cutting and coagulating wave.

症例は41歳女性.29歳より計5回の甲状腺乳頭癌の手術歴があり,1992年7月腹痛のため当科を受診した.下部消化管精査の結果大腸全域にびまん性の腺腫性ポリープが密生し,また,横行結腸に全周性の内腔狭窄を併う2'型大腸癌,S状結腸に1'型大腸癌,下行結腸にIsp'型大腸癌を認めた.胸部X線,肺CTにて3カ所に小結節陰影が認められ,大腸癌及び甲状腺乳頭癌の肺転移を伴った家族性大腸腺腫症と診断し,全結腸切除回腸直腸吻合術及び肺部分切除術を施行した.家族性大腸腺腫症は放置すればほぼ100%大腸癌に罹患することが知られているが,甲状腺乳頭癌を重複した報告は稀であり,文献的考察を加えて報告した.
