Objective To assess the necessity and effectiveness of salpingectomy before IVF-ET for hydrosalpinx among Chinese infertile patients.
Methods The relevant papers published from 2000 to December of 2010 in China were electronically searched in CBM, VIP and CNKI to collect randomized controlled trials (RCTs) involving Chinese hydrosalpinx women with or without salpingectomy before IVF-ET. The quality of the included trials was independently assessed by two reviewers, and the data were extracted and analyzed by RevMan 5.0 software.
Results Nine RCTs involving 687 patients and 730 IVF-ET cycles were identified. The results of meta-analyses showed that: a) There were significant differences between the two groups in Gn dosage (WMD=1.23, 95%CI 0.17 to 2.30, P=0.02), fertilization rate (RR=1.07, 95%CI 1.02 to 1.13, P=0.006), cleavage rate (RR=1.05, 95%CI 1.00 to 1.09, P=0.03), clinical pregnancy rate (RR=1.92, 95%CI 1.41 to 2.61, P lt;0.000 1), and abortion rate (RR=0.34, 95%CI 0.13 to 0.86, P=0.002); and b) There were no significant differences between the two groups in days of Gn (WMD= –0.27, 95%CI –0.59 to 0.06, P=0.11), E2 in HCG day (WMD=59.15, 95%CI –9.61 to 127.91, P=0.09), number of eggs (WMD= –0.27, 95%CI –0.44 to 0.99, P=0.46), quality embryonic rate (RR=1.02, 95%CI 0.91 to 1.14, P=0.79), and ectopic pregnancy rate (RR=0.22, 95%CI 0.03 to 1.82, P=0.16).
Conclusion The current evidence shows that salpingectomy before IVF-ET for hydrosalpinx Chinese hydrosalpinx patients is necessary and effective. For the low quality of methodology of the included studies, more reasonably-designed and double-blind RCTs with large sample are required to provide more high-quality proof.
