[Effect of different laparoscopic procedures for hydrosalpinx on pregnancy outcome of embryo transfer].

OBJECTIVE: To explore the effects of different laparoscopic procedures before embryo transfer (ET) for hydrosalpinx on pregnancy outcomes. METHODS: Group A (n = 269) underwent laparoscopic bilateral salpingectomy before ET while group B (n = 178) had laparoscopic bilateral tubal salpingostomy for hydrosalpinx. And the pregnancy outcomes of ET were evaluated. RESULTS: The implantation, pregnancy, abortion, ectopic pregnancy and live birth rates were similar in 2 groups (P > 0.05). The interstitial pregnancy rate was 10.27% after bilateral salpingectomy. The clinical pregnancy rate increased while the interstitial pregnancy rate decreased when the intervals between salpingectomy and ET were prolonged. But there was no statistical significance (P > 0.05). CONCLUSION: Laparoscopic tubal salpingostomy is as effective as salpingectomy for hydrosalpinx before ET. The interstitial pregnancy rate increases after laparoscopic salpingectomy. The interval between salpingectomy and ET should be appropriately scheduled.
