title: [Histopathologic findings of the trophoblast and tubal wall after medicamentous therapy of tubal pregnancies].
abstract: The purpose of the study was to evaluate the effects of drug therapy on the throphoblast and on the tubal wall when protaglandin F2 alpha (PGF2 alpha) was administered in cases of tubal pregnancies. 42 patients were divided into two groups: women of group I (n = 30) were secondarily treated by surgery because of raising serum HCG levels. Group II (n = 12) consisted of patients who were operated on because of acute symptoms (abdominal pains, intraabdominal haemorrhage), despite already failing HCG values. In group I in 66% (n = 20) of the histological specimens an intact (vital) trophoblast was found. Five cases (17%) showed partly necrotic gestational tissue, whereas in another five cases (17%) the whole trophoblast was necrotic. In patients of group II all ectopic pregnancies showed histological signs of necrosis. In the histopathology of the Fallopian tubes no signs of trophic regression could be found. However, ten out of 22 cases showed ruptured tubal pregnancies. In this analysis we could show that the instillation of PGF2a electively destroys the ectopic trophoblast and does not exercise any necrotic action on the tubal wall.
