[A comparable study of microwave tissue coagulation (MTC) and CO2 laser in treatment of cervical erosion]

In a randomized study, 300 patients with cervical erosion were allocated to either MTC(154) or CO2 Laser(146). The patients were treated on an outpatient basis without anesthesia. In the case of initial treatment failure the same method was to be used for retreatment. All the patients were followed-up for an average of 11 weeks (8-12). 142 of 154 microwave-coagulated patients (92.20%) and 116 of 146 Laser-evaporated patients (79.45%) were cured after one treatment, and there was significant difference between MTC and Laser group (P < 0.005). Bleeding during operation occurred in 5 of 154 MTC group (3.25%) and 32 of 146 Laser group (21.92) (P < 0.005). The result suggested that MTC had higher cure rate and less complications. It is easy to handle, safe and economic.
