title: [A comparison between CO2 laser conization and cold knife conization in clinical diagnosis of cervical intraepithelial neoplasia].
abstract: Intraoperative and postoperative complications related to CO2 laser conization and cold knife conization were compared. From 1980 to 1984 66 patients were hospitalized for cold knife conization, the mean operative time was 28.1 minutes, all patients had epidural anesthesia, and the mean time of admission was 6.8 days. Three percent of cases had infections, the mean intraoperative hemorrhage was 75 ml, and the rate of remaining foci of neoplasia was 18.2%. Meanwhile there were 116 patients hospitalized for CO2 laser conization from 1985 to 1987. The mean operative time was 15.6 minutes, 15.5% of cases had local anesthesia, the mean time of admission was 0.6 days. Zero percent of cases had infections, 0% of cases had postoperative cervical stenosis, the mean intraoperative hemorrhage was 75 ml, and 29.5% of cases had remaining foci of neoplasia. There was no significant difference in hemorrhage amounts at hysterectomy following conization either method. Thus, in our experience, CO2 laser conization is more effective for clinical diagnosis and treating of cervical intraepithelial neoplasia.
