title: Radiosurgery in the management of cervical intraepithelial neoplasia.
abstract: OBJECTIVE
  To evaluate the loop electrosurgical excision procedure (LEEP) and large loop excision of the transformation zone-conization (LLETZ-conization) in the management of cervical intraepithelial dysplasia using high-frequency, filtered waveform energy (radiosurgery).
  
  
  METHODS
  Two hundred thirteen women attending the outpatient cervical colposcopy clinic with smears consistent with an epithelial abnormality, but macroscopically or colposcopically not consistent with invasive carcinoma, were included in the study. LEEP and LLETZ-conization were performed in 72 and 141 women, respectively. A matched pair group of patients undergoing cold knife conization was used for the comparison with LLETZ-conization. Using LEEP, in 83% a clear resection margin of the biopsy specimen was achieved. In this subset, diagnosis and therapy were achieved in a single visit. No complications, such as hemorrhage, occurred during the operation or postoperative period.
  
  
  RESULTS
  Comparison of LLETZ-conization with the matched-pair group undergoing cold knife conization showed a significantly shorter duration of surgery for LLETZ-conization (mean, 10.8 vs. 16.5 minutes, P < .001). We found no differences concerning posttreatment bleeding complications (2.8% vs. 3.3%) or clear resection margins (92% vs. 86%). Patients undergoing LLETZ-conization needed significantly less analgesic (P < .01).
  
  
  CONCLUSIONS
  Radiosurgical loop excision is a safe and cost-effective method in the diagnosis and treatment of cervical intraepithelial neoplasia.
