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.
