Clinical study on loop electrosurgical excision procedure in the treatment of cervical intraepithelial neoplasia with high risk human papilloma virus (HRHPV) infection
ObjectiveTo study the clinical effects of loop electrosurgical excision procedure (LEEP) in cervical intraepithelial neoplasia (CIN) patients with high risk human papilloma virus (HRHPV) infection. MethodsNinetyeight CIN patients with HRHPV infection were treated with LEEP. All patients were performed with HRHPV test both before and after LEEP. Clinical effects of the patients were assessed. ResultsAll patients were successfully operated. The cure rate was 90.8% (89/98), and the recurrence rate was 9.2% (9/98) after 1 year followup. The cure rate in patients with CIN Ⅰ was 100% (64/64), significantly higher than 73.5% (25/34) in patients with CIN Ⅱ-Ⅲ(P<0.01), and the recurrence rate of patients with CIN Ⅰ was significantly lower than that of patients with CIN Ⅱ-Ⅲ(0% versus 26.5%,P<0.01). Positive rate of HRHPV was 31.6% (31/98) 6 months after the treatment, significantly lower than that before LEEP(P<0.01), and negative conversion rate was 68.4% (67/98); and 1 year later, they continued to decrease to 15.3% (15/98) and 84.7% (83/98), respectively, all with statistical significance (P<0.01). ConclusionLEEP is effective in the treatment of CIN, also it can eliminate most of the HR HPV infections, thus reduce the recurrence rate of CIN and incidence of cervical cancer. In addition, it′s easy to operate, with fewer complications, and worthy of promotion.
