Effectiveness of laparoscopic tubal anastomosis in tubal occlusion patients after laparoscopic salpingostomy for tubal pregnancy

Abstract

Objective To evaluate the effectiveness of laparoscopic tubal anastomosis for tubal occlusions associated with infertility in patients with previous laparoscopic salpingostomy for ectopic pregnancy. Methods This study is a retrospective analysis of the pregnancy outcomes of 173 infertile patients who underwent hysteroscopy and laparoscopic tubal anastomosis treatment between January 2013 and August 2018 in the Department of Reproductive Endocrinology in West China Second University Hospital of Sichuan University. All patients had a history of laparoscopic salpingostomy for tubal pregnancy. The primary outcomes were intrauterine pregnancy, ectopic pregnancy, and delivery rates. We further studied the associated factors that could influence the change in pregnancy status. Results The 24‐month cumulative clinical pregnancy rate of all patients was 107/173 (61.8%). The distribution of outcomes for the entire group of pregnancies was as follows: intrauterine pregnancy rate, 76/173 (43.9%); ectopic pregnancy rate, 31/173 (17.9%); delivery rate, 68/173 (39.3%); and miscarriage rate, 8/173 (4.6%). Age, type of anastomosis, hydrosalpinx, and endometrial polyps were significant prognostic factors in the multivariate model. Conclusion Laparoscopic tubal anastomosis is an effective treatment for tubal‐associated infertility due to previous laparoscopic salpingostomy for ectopic pregnancy, especially for women under 35 years of age.
