[Notes on cryosurgery in proctology]

The A. in a review of the outpatient proctologic practice suggest the application of the crioprobe to the piles first and second degree, and to polyps small ones. A pathogenetic hypothesis of this narrowing application is supported on the basis of the unpractible mucosa, affected by 3rd degree piles. Furthermore the N2O employment seems to be unusefull in the treatment of the polyps and a further improvement of the probes is required.
