RESUMEN
Objective:To study the effectiveness of Loop electrosurgical excision procedure (LEEP) in the diagnosis and management of cervical intraepithelial neoplasia(CIN). Methods: 155 patients with CIN were diagnosed by cervical biopsy under colposcopy. All cases were treated with LEEP and the operative time, bleeding volume, cervical biopsy results before and after LEEP were evaluated, and the effects and cervical regeneration were followed up. Results: The mean operative time of LEEP was 6. 8 minutes. The mean bleeding volume was 9.6m1. Pathological diagnosis of CINI CIN Ⅱ CIN Ⅲ after LEEP were positively correlated to directed biopsy by colposcopy. The correlation coefficient was 0.785 ( P < 0.01). The cure rate of LEEP was 98.6%. Among the 151 cases, 134 (88. 7%) were satisfactory cervical regeneration. Conclusions: LEEP is one of the effective and safe methods for the diagnosis and treatment of CIN.
