title: Microscopic evidence of silent inflammation in grossly normal fallopian tubes with ectopic pregnancy.
abstract: A normal laparoscopic examination of the pelvis in an infertile patient is usually considered sufficient evidence of normal tubal function. Twelve of 27 tubal ectopic pregnancies which occurred over a 4-year period in patients attending an infertility clinic were in patients with a previously "normal" laparoscopy. In eight patients, salpingectomy was performed, and the whole tube was available for examination by a single pathologist. The eight fallopian tubes, thoroughly examined histologically, all had evidence of ongoing, low-grade salpingitis or postinflammatory endosalpingeal disorganization in areas away from the ectopic pregnancy. These findings suggest that laparoscopy does not exclude significant microscopic tubal disease in at least some women with an apparently normal pelvis, and that this may be a cause of ectopic pregnancy and perhaps "idiopathic" infertility.
