Cold polypectomy is an excellent treatment for conventional polypectomy in terms of safety, convenience and cost, and this procedure is gradually spreading in Europe, the US and Japan.
The safety and treatment outcome of cold polypectomy have improved due to improvements in the procedure and the device.
Furthermore, the safety of cold polypectomy in patients who are taking antithrombotic drugs was recently reported.
However, cold polypectomy has a disadvantage in that histopathological stump evaluation is difficult and resection depth is shallow. In addition, the rate of recurrence and long-term prognosis in patients who underwent cold polypectomy are not clear.
It is important to understand these problems and to perform cold polypectomy for the appropriate lesions.
In the current guidelines in Japan, excision of lesions with a diameter of 5 mm or less by cold polypectomy is not recommended, because of the incidence of accidents with hot polypectomy. However, the resection of adenomatous lesions regardless of size by cold polypectomy is performed in Europe and the US, and may be recommended in Japan in the future.
