A mobile aerosol cryotherapy device (Histofreezer) for treatment of cervical contact bleeding: a pilot study.
This study aims to evaluate the efficacy of the Histofreezer (a mobile aerosol cryotherapy device) treatment for women with cervical contact bleeding. Ten healthy women aged 22-50 years referred to our outpatient colposcopy clinic for recurrent postcoital or contact bleeding, and who suffered from mild to wide ectropion with bleeding on contact were studied. All women had a normal pelvic examination and ultrasound and a normal colposcopy and PAP smear. They were treated with the Histofreezer, which freezes the tissue to a temperature of -55 degrees C. A picture of the cervix was taken by a cervical camera before, after the procedure and during follow-up visits 4 and 8 weeks afterwards. There was a complete resolution of bleeding ectropion with a good healing of squamous metaplasia in seven patients. Two women showed partial improvement. Based on this initial study, this short and simple ambulatory treatment shows good results, both subjectively and on follow-up colposcopy.
