[Conservative laparoscopic treatment of bilateral ectopic pregnancy. 2 case reports and review of the literature].

Ectopic pregnancy is a frequent clinic entity, with an incidence from 4.5 to 16.8 for 1000 pregnancies. The frequency of ectopic pregnancy has been triplicated in the last years, mainly owed to increase of sexual transmitted diseases, increase in salpinges' surgery and in assisted reproductive medicine. The ectopic pregnancy is also the most frequency cause of maternal death during the first trimester of pregnancy. The frequency of bilateral tubal ectopic pregnancy is extremely rare, it is reported from 1:125 to 1:1580 of all ectopic pregnancies. The first case of bilateral tubal ectopic pregnancy was reported n 1918 by Bledsoe. In Mexico, Molina described the first case in 1993, with conservative laparoscopic treatment. Two clinic cases are presented of bilateral ectopic pregnancy, treated conservatively by laparoscopy. The first one with background of sterility because of anovulation, receiving treatment with menotropins for ovarian hyperstimulation, the other one. In the second case, was a spontaneous pregnancy, in a patient with a history of several pelvic surgeries. In this case a bilateral salpingostomy was realized. In both cases was demonstrated chorionic villi by histopathology. These cases are a model of nature to evaluate the real utility of several diagnostic and therapeutic methods which are available nowadays for the treatment of ectopic pregnancy.
