Cochrane review: Post-operative procedures for improving fertility following pelvic reproductive surgery

Abstract

The objectives of the study was to determine the effectiveness of post-operative procedures following female pelvic reproductive surgery. A systematic review employing the principles of the Cochrane Menstrual Disorders and Subfertility Group was used. Five randomized controlled trials were included. Participants were women undergoing pelvic reproductive surgery; interventions were any post-operative procedure designed to improve fertility; outcomes were pregnancy, live birth, ectopic pregnancy and miscarriage rates and the rates of tubal patency and procedure-related complications. Summary statistics were expressed as odds ratios. The results showed that the odds of pregnancy, live birth, ectopic pregnancy and miscarriage were not significantly altered by post-operative hydrotubation nor second-look laparoscopy with adhesiolysis. Whether hydrotubation was early or late and whether hydrotubation fluid contained steroid or not had no significant impact on the odds of pregnancy, live birth, ectopic pregnancy or miscarriage. The odds of pregnancy and live birth were significantly increased and infective complications significantly decreased by hydrotubation with fluid containing antibiotic compared with hydrotubation with fluid containing no antibiotic, in late hydrotubation following tubal stent removal 6 weeks after tubal surgery. The odds of at least one patent Fallopian tube were significantly increased with late hydrotubation following tubal stent removal compared with early hydrotubation in women who had no tubal stenting, but this intervention had no significant impact on the odds of pregnancy, live birth, ectopic pregnancy or miscarriage. In conclusion, there is insufficient evidence to support the routine practice of hydrotubation or second-look laparoscopy following female pelvic reproductive surgery. The studies on which this conclusion is based were either poor quality or underpowered. Post-operative hydrotubation with fluid containing antibiotic following tubal surgery may offer benefit over hydrotubation fluid without antibiotic. A randomized controlled trial of post-operative hydrotubation with antibiotic-containing fluid versus no hydrotubation for improving fertility following tubal surgery is justified.
