A histopathologic study of 84 ampullary and seven isthmic tubal ectopic pregnancies was conducted. In 52.2% of ampullary pregnancies, the gestations were found intraluminally, and in most of these cases (85.1%), the muscularis was preserved. In isthmic pregnancies, the gestations were usually found extraluminally or both intraluminally and extraluminally. The disruption of the tubal wall was more extensive in isthmic pregnancy. This study suggests that in isthmic pregnancy, the trophoblast penetrates the tubal wall relatively early. It appears that linear salpingostomy could be done for ampullary pregnancy without jeopardizing luminal integrity. Its use for isthmic pregnancy is still unclear.
对84例壶腹部输卵管妊娠和7例峡部输卵管妊娠进行了组织病理学研究。在52.2%的壶腹部妊娠中，妊娠物位于管腔内，且在大多数此类病例（85.1%）中，肌层得以保留。在峡部妊娠中，妊娠物通常位于管腔外或同时位于管腔内和管腔外。峡部妊娠时输卵管壁的破坏更为广泛。本研究表明，在峡部妊娠中，滋养层相对较早地穿透输卵管壁。对于壶腹部妊娠，似乎可以进行线性输卵管造口术而不损害管腔完整性。其在峡部妊娠中的应用仍不明确。
