Abstract
The authors report their experience of the use of a vital stain--methylene blue--as a surgical guide in laser cervical conization for CIN2-CIN3/CIS. During the period 1 October 1991-31 December 1992 a total of 40 laser cervical conizations were performed under local anesthesia using a CO2 laser connected to a microhandpiece and colposcope in patients with exo-endocervical lesions which were histologically positive for CIN2-CIN3/CIS. In 33/40 patients an aqueous solution of 1% methylene blue was introduced preoperatively in the endocervix using a cotton-wool bud with consequent impregnation of the pseudoglandular crypts: laser biopsy was performed along the guidelines of the stain itself. This enabled the direction of resection to be varied: in 3 patients due to an anomalous and eccentric direction of cervical canal; in 10 patients to remove glandular structures surrounding or underneath lesions; in 8 patients following pseudoglandular section to carry out deep vaporization (3 patients) or correct cutting edges (5 patients). The apex and edges of the cone were always intact. Fourteen patients completed a 12-month follow-up and a further 6 were followed up for 9 months; only 1/14 patients (with AIDS) showed recidivation after 1 year. In the authors' experience the use of a vital stain as a guide during laser cervical cone biopsy is an easily used method which ensures the greatest possible respect for healthy cervical structures, also in order to preserve fertility in young patients.
