Uterine surface temperature changes caused by electrosurgical endometrial coagulation.
To assess the risk for transmural thermal injury to abdominal viscera during electrosurgical ablation of the endometrium, thermocouples were laparoscopically directed to the surface of the uterus at the time of endometrial ablation. A 2- or 5-mm ball, or a barrel electrode directed through a urologic resectoscope was placed in the cornual area, and current varying from 50 to 150 W of unmodulated ("cutting") or modulated ("coag") current was applied for five seconds without moving the electrode. The resultant temperature rise of the uterine serosa did not exceed 6 degrees C.
