[Tubal histology in extra-uterine pregnancies].

141 patients affected by tubal pregnancy have been treated by total salpingectomy at the Port-Royal university clinic between the 1st January 1977 and the 31st January 1984. Tubal pregnancy occurred in the majority of cases in a pathological Fallopian tube, of which the histological state was unrelated to the clinical observations made at laparotomy. Ampullary pregnancy (88% of cases) is secondary to a pathological ampulla in 94 p. cent of cases. The latter was chronic salpingitis in 92 p. cent of cases. Isthmic pregnancy (12% of cases) appears to us to be secondary to isthmic pathology in all cases, and is generally associated with ampullary lesions. There also chronic salpingitis preponderates, whilst endometriosis is very rare. The great frequency of pre-existing lesions which we have noted explains perfectly the high level of recurrences in situ observed after conservative surgery of the gravid tube.
