[A clinical study on the complications associated with laser therapy for cervical neoplasia].
Six hundred and fifty-nine patients with cervical neoplasia were treated by either vaporization (395 patients) or excisional conization (264 patients) with various Lasers. The complications associated with the therapies were examined with reference to the Laser sources and in the local anesthesia and non anesthesia groups. Six hundred and thirty-nine patients were treated on an outpatient basis without local anesthesia (37.7%) or with local anesthesia (62.3%). During the procedures, the patients complained of pain and a hot sensation in the lower abdomen in 64.6% in the vaporization (vapor) group and 60.7% in the conization (cone) group. In the local anesthesia group, 2.9% of the vapor and 4.0% of cone group complained of nothing. Uncontrollable bleeding during the procedures was most common in 12.8% and 32.3% in the CO2 vapor and cone groups, respectively. Misirradiation of the vaginal wall and vulva occurred in 3.3% in all vapor groups. On the other hand, the incidence of burns to both areas in all cone groups was 7.2%. The patients who were given an analgesic were 1.3% in all vapor groups and 2.5% in all cone groups. Delayed bleeding in those who received some treatment to stop it occurred in 14.7% in all vapor groups and also in 11.0% in all cone groups. Cervical stenosis was seen in 3.8% in all vapor groups and in 8.6% in all cone groups. No infection of the lasered site was observed in the vapor groups, but was observed in 0.8% in the cone groups. The culture test showed both E. coli positive.
