医用几丁糖联合大剂量雌激素预防宫腔再粘连的比较研究

目的探讨宫腔镜下宫腔粘连分离术后医用几丁糖联合大剂量雌激素预防宫腔再粘连的临床效果。方法2008年3月～2011年6月80例宫腔粘连在我院行宫腔镜下宫腔粘连切除术,根据术后防粘连方法的不同分为研究组及对照组：研究组41例,术毕予医用几丁糖2.5 ml,术后口服戊酸雌二醇片3 mg,Q12 h,共21 d;对照组39例,术毕置放宫内节育器,术后口服戊酸雌二醇片1 mg,QD,共21 d。结果研究组宫腔镜手术后宫腔再粘连3例,此3例术前均为重度粘连,分离2次后均成功。对照组宫腔镜手术后宫腔再粘连9例,其中3例术前为中度粘连,6例为重度粘连,3例分离2次成功,余6例随访3个月B超示子宫内膜菲薄（〈5 mm）,回声不连续。研究组再粘连率7.3%（3/41）明显低于对照组23.1%（9/39）（χ2=3.894,P=0.048）。结论宫腔粘连术后医用几丁糖联合大剂量雌激素能有效预防再粘连。
