The field of cryosurgery in proctology can be seen in therapy of inoperable anal and rectal carcinomas. It is aimed at improving life quality. The role of microcirculation as a factor causing a contrary heating effect can be proved by intravital microscopy. Cryodestruction is limited by this factor. By means Of measurements of temperature we know the boundaries of complete tissue destruction which is reached in a distance of 4-8 mm. Our own number of cases consists of 122 patients with a mean age of 72 years.
直肠病学中的冷冻外科领域可用于无法手术的肛管和直肠癌的治疗。其目的是提高生活质量。微循环作为产生相反加热效应的一个因素，其作用可通过活体显微镜检查得到证实。冷冻破坏受该因素限制。通过温度测量，我们知道在4 - 8毫米的距离内可达到完全组织破坏的范围。我们自己的病例数为122例患者，平均年龄72岁。
