In a review of the world's literature on combined intrauterine and extrauterine pregnancies, 589 cases, including five cases currently reported from the Sloane Hospital for Women, were documented. Analysis of the literature revealed abdominal pain to be the most frequent presenting symptom. A combination of signs and symptoms, including abdominal pain, adnexal mass, peritoneal irritation, and an enlarged uterus, was the most significant finding in support of a presumptive diagnosis of combined gestations. At the Sloane Hospital for Women, the occurrence of both pelvic inflammatory disease and combined pregnancy is approximately three times the reported world incidence. This proportionate increase in both disease states may support a potential etiologic association between pelvic inflammatory disease and simultaneous intrauterine and extrauterine gestations.
在一篇对全球关于宫内宫外合并妊娠的文献综述中，记录了589例病例，其中包括斯隆女子医院目前报告的5例。对文献的分析显示，腹痛是最常见的首发症状。包括腹痛、附件包块、腹膜刺激征和子宫增大在内的一系列症状和体征组合，是支持双胎妊娠初步诊断的最重要发现。在斯隆女子医院，盆腔炎和合并妊娠的发生率约为全球报告发病率的三倍。这两种疾病状态的相应增加可能支持盆腔炎与同时发生的宫内和宫外妊娠之间存在潜在的病因学关联。
