目的:探讨宫颈上皮内瘤变(CIN)Ⅰ-Ⅱ级患者用聚焦超声治疗后的妊娠及其结局。方法:回顾性分析2005年1月至2007年6月因CINⅠ-Ⅱ行聚焦超声治疗的254例后分娩患者的妊娠时间、妊娠结局和终止妊娠方式。结果:254例患者,年龄20-36岁,平均(27.36±2.26)岁。254例妊娠患者中,3例异位妊娠,8例流产,243例分娩。在已分娩的243例患者中,3例早产,早产发生率为1.23%(3/243);18例胎膜早破,胎膜早破发生率为7.41%(18/243);无足月低体重儿发生;65例顺产,2例产钳助产,155例行剖宫产术,剖宫产率为63.98%(155/243)。剖宫产率较同期产科剖宫产率有显著统计学差异(χ2=14.7621,P<0.01)。分析剖宫产原因,其中因社会因素而选择剖宫产的高达30例,去除该因素后,剖宫产率为51.44%,与同期剖宫产率51.32%相比无差异(χ2=0.001 37,P>0.05)。结论:宫颈聚焦超声是治疗宫颈上皮内瘤变Ⅰ-Ⅱ安全有效的方法,对患者的妊娠及其结局无明显影响,不增加早产和低出生体重儿发生率。
Objective: To investigate the pregnancy and outcome of patients with grade Ⅰ-Ⅱ cervical intraepithelial neoplasia (CIN) treated with focused ultrasound. Methods: The pregnancy time, pregnancy outcome and termination of pregnancy in 254 patients with postpartum delivery who underwent CIN I-II Focused Ultrasound from January 2005 to June 2007 were analyzed retrospectively. Results: 254 patients, aged 20-36 years, with an average of (27.36 ± 2.26) years. Among 254 pregnant women, 3 had ectopic pregnancy, 8 had abortion, and 243 had childbirth. Among the 243 patients who had given birth, 3 were premature and the rate of preterm delivery was 1.23% (3/243). The incidence of premature rupture of membranes and premature rupture of membranes in 18 cases was 7.41% (18/243) 65 cases of normal birth, 2 forceps midwifery, 155 cases of cesarean section, cesarean section rate was 63.98% (155/243). Cesarean section rate over the same period of obstetric cesarean section rate was significantly different (χ2 = 14.7621, P <0.01). Analysis of cesarean section causes, which due to social factors and choose cesarean section up to 30 cases, after removal of this factor, cesarean section rate was 51.44%, with the same period of cesarean section rate was 51.32% no difference (χ2 = 0.00137 , P> 0.05). CONCLUSION: Cervical Focused Ultrasound is a safe and effective method for the treatment of cervical intraepithelial neoplasia Ⅰ-Ⅱ. It has no significant effect on the pregnancy and its outcome, and does not increase the incidence of preterm and low birth weight infants.
