[Results of cryosurgery in the treatment of inoperable tumor stenoses of the anus and rectum].
Inoperable tumor stenosis of anus and rectum may be treated surgically only by implantation of artificial anus. Cryosurgery proves to be a feasible alternative in order to maintain free passage of the gut. The cryoprobe is introduced through a rectoscopy under direct view. Visible tumor is touched with the tip of the cryoprobe and subsequently temperature is lowered to approximately -19 degrees C. Usually anesthesia is not required. From 1976 to 1989, 213 patients had been treated by cryosurgery in our department. In 23 cases the use of an artificial anus became inevitable afterwards.
