[Development of cryosurgery treatment methods in inoperable anus and rectum cancer and their introduction to general practice].
The domain of cryosurgery in proctology is in the field of inoperable anal and rectal carcinoma therapy with the aim of improving living quality. By intravital microscopy the role of microcirculation as the causative factor for counterheating could be proved. There by the cryodestruction is restricted. By temperature measurements we know that the limit for absolute tissue destruction is given at 3-8 mm tissue depth. A new device for cryosurgical treatment of inoperable anal and rectal carcinoma was developed (2nd generation of the device) and introduced into praxis. A total of 247 cases were our own patients at the average age of 75 years and a lethality of 0.25%. Generally, an improvement of living quality was achieved by the cryotherapy in those patients with stenosing colorectal carcinoma. 50% of all patients lived longer than 2 years. In 242 patients of the total of 247 cryosurgically treated patients the establishing of an anus praeter could be spared.
