[Comparative study of cryosurgery and hysterectomy in the treatment of cervical intraepithelial neoplasia]. / Estudio comparativo de criocirugía e histerectomía en el tratamiento de la neoplasia intraepitelial cervical (NIC).

The purpose of this study was to compare the results of conservative management with cryosurgery and with hysterectomy in different stages of NIC. The records of 235 treated patients from 1984 to 1991, were reviewed; 140 patients were treated with cryosurgery and 95 with total hysterectomy. Cure rate was for stage I in 34 patients (94.5); for stage II in 54 patients (98.2%), and for stage III in 46 patients (93.9%). For hysterectomy in NIC I in 5 patients (100%); for NIC II in 15 (100%), and for NIC III in 74 (98.66%). Statistical study with square Chi showed a not significant P which means that there is no difference in the results of Cure and No Cure in both procedures. It is concluded that intraepithelial cervical neoplasia may be managed with both procedures, provided that the established criteria for cryosurgery and hysterectomy, are followed.
