Objective:
To assess the ability of a synthetic hygroscopic cervical dilator to make an unsatisfactory colposcopic examination satisfactory, thereby avoiding cervical conization.
Materials:
From April 1991 to March 1993, 30 women with unsatisfactory colposcopic examinations underwent repeat colposcopy after a synthetic hygroscopic cervical dilator had been placed in the endocervical canal for approximately 2 hours.
Results:
The reasons for initial unsatisfactory colposcopy in the 30 patients were squamocolumnar junction not seen in its entirety (18 patients, 60%), lesion not seen in its entirety (ten, 33%), and neither transformation zone nor lesion seen in their entirety (two, 7%). Complications were encountered in one patient from whom the dilator could not be removed completely. Of 29 patients undergoing repeat colposcopy, 23 (79%) had satisfactory examinations. In 15 of 30 patients, conization was avoided; it was required in six of 30 (20%) women for persistent unsatisfactory colposcopy (including the patient in whom the dilator broke) and in nine of 30 (30%) for other indications.
Conclusions:
This experience suggests that a synthetic hygroscopic cervical dilator can be used in patients with an unsatisfactory colposcopy to achieve a satisfactory examination, thus avoiding cervical conization.
