[Pathological findings of proximal tubal occlusive infertility].

Exicised tubal segments (including interstial and isthmic portions) from 33 women with proximal tubal occlusive infertility were examined pathologically. We found that pathologic entities included chronic tubal inflammation (70.59%), tubal endometriosis (9.80%), obliterative fibrosis (7.84%), salpingitis isthmica nodosa (5.88%), tubal tuberculosis (3.92%). Only one of the tubes (1.96%) showed no obvious pathological change. These observations on proximal tubal occlusion in combination with clinical features and pelvic changes indicate that: (1) These are multiple distinct pathologic patterns, and pelvic findings do not predict the pathologic changes of the tubes. (2) Induced abortion and uterine curetage is an important factor for the proximal tubal occlusive infertility. Pelvic inflammatory disease and intrauterine device are other factors.
