Cervical os obliteration after laser surgery in patients with amenorrhea

Thirty-eight postmenopausal women and one with pituitary amenorrhea underwent cervical laser surgery. The cervical canal of each patient was patent 2 weeks later. Eighteen of the 30 women reevaluated 4-48 months later had total obliteration of the cervical canal. Five other patients had severe cervical stenosis. This outcome makes continued adequate cytologic and colposcopic surveillance of these patients impossible and leaves them at risk for developing unrecognized cervical and endometrial disease
