[Tubal causes of ectopic pregnancy]

141 patients with tubal pregnancies underwent complete salpingectomy in the department of obstetrics and gynecology at Port Royal, Paris between January 1, 1977-January 31, 1984. Usually, a tubal pregnancy occurs in the affected tube. Ampullary pregnancy (88%) is the result, in 95% of the cases, of ampullary pathology. Isthmic pregnancy (12%) is probably due, in every case, to a pathology of the isthmus which is generally associated with ampullary disease. In these cases, too, chronic salpingitis is usually the reason while endometriosis is very rare. The high rate of reoccurrence after conservative surgery results from the high rate of initial tubal alterations. (author's modified)
