少见部位异位妊娠分析及误诊防范

Ectopic pregnancy analysis and misdiagnosis of prevention

目的探讨少见部位异位妊娠的临床特征及误诊原因。方法对2008-06—2011—03收治的33例少见部位异位妊娠进行回顾性分析。结果少见部位异位妊娠发生率占同期异位妊娠6．5％，以宫角妊娠最多见（9／33，占27．3％），其余为输卵管间质部妊娠、卵巢妊娠（7／33，占21．2％）及子宫肌壁间妊娠（4／33，占12．1％），术前误诊率63．6％。所有患者均行手术治疗，视术中情况行异位妊娠灶切除，33例均治疗成功，无手术并发症。结论少见部位异位妊娠临床表现不典型，术前诊断较困难，一旦怀疑本病应及早手术探查明确诊断。

Objective To explore the clinical characteristics and misdiagnosis reasons of special-site ectopic pregnan- cy. Methods The retrospective analysis was performed on 33 cases of special-site ectopic pregnancies in our hospital from June 2008 to March 2011. Results The incidence in special site of ectopic pregnancy was 6.5%, most of them was cornual pregnancy （9/33 cases, 27.3% ）, the others were interstitial pregnancy, ovarian pregnancy （7/33 cases, 21.2%） and intramural pregnancy （4/33 cases, 12.1% ）. The preoperative misdiagnosis rate was 63.6%. All the patients received the operation, according to situations, some patients got the focal resection of ectopic pregnancy. ALL the patients were treated successfully, and no severe complications occurred. Conclusion The clinical fea tures of special site ectopic pregnancy is not typical, so it is difficult for preoperative diagnosis. If there is a suspicion of the disease, surgical exploration should be preformed earlier to get better therapeutic effects.
