The variety of the extrauterine pregnancy clinical picture makes even the most experienced clinicians affirm that "the most characteristic symptom of extrauterine pregnancy is the fact that in most cases it has no characteristic symptoms and each case has its specific features." In the author's opinion it is obviously a case of ectopic pregnancy in the ampullar part of the left tube on its way out like a tubal abortion. The still fresh chorionic villi have arroded the peritoneum of the posterior abdominal wall and reached the retroperitoneal surface carrying away the ampule. This localization is an extremely rare phenomenon.
“宫外孕最典型的症状是，在大多数情况下它没有典型症状，且每个病例都有其独特之处。”作者认为，这显然是一例左侧输卵管壶腹部宫外孕，类似于输卵管流产。新鲜的绒毛膜绒毛侵蚀了后腹壁的腹膜，到达腹膜后表面并带走了壶腹。这种定位是一种极为罕见的现象。
