The authors describe their one year's experience with a CO2 Laser in gynaecology. They emphasise the ease of use of the equipment. Three major divisions of gynaecology can benefit from the CO2 Laser: benign or precancerous lesions of the vulva and of the vagina, dysplasia of the cervix, surgery of the fallopian tubes. In the future, technical progress will enable the CO2 Laser to be used in laparoscopy and its indications will certainly be extended to laparoscopic surgery.
