[Treatment of human papilloma virus of the cervix using cryosurgery]

The causal lesions by VPH in the cervix, are associated to cancer. Currently 56 different subtypes have been isolated, from which, the 16, 18, 31, 33, 35 and 39 are more frequently related with the cervical intraepithelial neoplasia; from here derives the importance of opportune treatment. The objective of this paper is to evaluate VPH of the cervix opportune treatment with cryosurgery. Seventy five patients were analyzed, from April 1988 to May 1990 with diagnosis of cervical VPH, by cytology, colposcopy and histopathology; in whom cryosurgery with double freezing technique, was practiced; and were evaluated ever six months, during two years with cytology and colposcopy. Whenever there was persistence or recurrence, cryosurgery was used again; doing this even three times, previously discarding intraepithelial cancer. Seventy seven per cent of the patients received only one session; 16% two, and 7% three. At the six months review, it was found that 92% of the cases were negative, and 8% with persistence; at 12 months, 89% negative and 11% with recurrences; at 18 months, 93% negative, 3% with persistence and 4% with recurrence; at 24 months, 96% negative and 4% with recurrence. It is concluded that cryosurgery is efficacious in the treatment of these lesions, easy to use, well tolerated, with minimal side effects, it does not require anesthesia and is of a low cost.
