Abstract:
Retroperitoneal ectopic pregnancies are extremely rare; only a few cases having been reported. Here, we report laparoscopic removal of an asymptomatic retroperitoneal ectopic pregnancy from a 29-year-old woman who was referred to our hospital for a suspected ectopic pregnancy. Transvaginal ultrasound did not reveal a gestational sac in the uterus or pelvic cavity. However, abdominal contrast-enhanced computer tomography showed a gestational sac between the abdominal aorta and inferior vena cava. On laparoscopy, the gestational sac was confirmed to be in this retroperitoneal location and successfully removed with minimal bleeding. Histopathologic examination revealed chorionic villi surrounded by lymphatic tissue, suggesting lymphatic spread of the retroperitoneal ectopic pregnancy. In summary, contrast-enhanced computer tomography is very useful for locating the site of pregnancy in women suspected of having a retroperitoneal ectopic pregnancy. Timely diagnosis of a retroperitoneal ectopic pregnancy before bleeding occurs can enable their safe laparoscopic removal.
摘要:
腹膜后异位妊娠极为罕见;仅报道了少数病例。这里,我们报告一名29岁女性因疑似异位妊娠而转诊至我们医院,腹腔镜切除无症状腹膜后异位妊娠.经阴道超声检查未发现子宫或盆腔有孕囊。然而,腹部对比增强计算机断层扫描显示腹主动脉和下腔静脉之间有一个孕囊.在腹腔镜检查中,妊娠囊被证实位于腹膜后位置,并成功切除,出血最少.组织病理学检查显示绒毛膜绒毛被淋巴组织包围,提示腹膜后异位妊娠的淋巴扩散。总之,对比增强计算机断层扫描对于定位怀疑患有腹膜后异位妊娠的女性的妊娠部位非常有用。在出血发生之前及时诊断腹膜后异位妊娠可以安全地进行腹腔镜切除。
