The investigation for usefulness of imprint smear in ectopic pregnancy

For 18 ectopic pregnancies, we performed imprint cytology cytology of the tuba uterina at the operation. We studied the accuracy of imprint cytology in contrast with pathological specimens. By macroscopic examination, we confirmed villi in 11 of the 18 cases. By microscopic examination, we confirmed villi in three cases in which we could not confirm the villi by macroscopic examination. By cytological examination, we detected trophoblasts in all 18 cases. In conclusion, imprint cytology of the tuba uterina is a useful means of decting ectopic pregnancy.
