Salpingectomy for repeated embryo nonimplantation after in vitro fertilization in patients with severe tubal factor infertility

Management of Hydrosalpinx in the Era of Assisted Reproductive Technology: A Systematic Review and Meta-analysis

OBJECTIVE

To conduct a systematic review and meta-analysis evaluating the effect of hydrosalpinx on pregnancy outcomes, to compare different types of management of hydrosalpinx and their impact on pregnancy rates as well as on the ovarian reserve.

DATA SOURCES

Electronic search using Pubmed, EMBASE, Ovid MEDLINE, Google Scholar, ClinicalTrials.gov, and Cochrane Central Register of Controlled Trials and including all published studies that examined tubal infertility and its management (assisted reproductive technology or surgery) as well as the effects on ovarian reserve. The following medical subject headings (Mesh) terms combinations were used: "fallopian tube disease," hydrosalpinx," "tubal or salpinx occlusion or obstruction," "in vitro fertilization," "fallopian tube surgery," "salpingectomy," "salpingostomy," "infertility," "subfertility," "sterility" and "ovarian reserve."

METHODS OF STUDY SELECTION

All randomized trials, cohort, and case controls studies were included. We excluded review articles, meeting abstracts, case series and case reports, and abstracts without access to full texts. The search was limited to trials in humans and published in English.

TABULATION, INTEGRATION, AND RESULTS

Our electronic search initially retrieved 6354 articles. Finally, 19 studies were included in the quantitative evaluation of the effects of hydrosalpinx: 23 in the qualitative evaluation and 5 in the quantitative evaluation of different types of hydrosalpinx treatments; and 17 in the quantitative evaluation of ovarian reserve. The presence of a hydrosalpinx was associated with decreased rates of implantation and clinical pregnancy, and increased rates of ectopic pregnancy and miscarriage. Management of hydrosalpinx with salpingectomy, tubal occlusion, or hydrosalpinx aspiration led to better in vitro fertilization pregnancy rates. We found no difference in ovarian response to stimulation after salpingectomy except a decrease in antimüllerian hormone compared to no surgery.

CONCLUSIONS

The presence of hydrosalpinx is associated with decreased pregnancy rate and increased rates of ectopic pregnancy and miscarriage. Management of hydrosalpinx, regardless of the type of treatment, leads to an increased chance of pregnancy.

Is laparoscopy necessary before assisted reproductive technology?

PURPOSE OF REVIEW

Laparoscopy is widely used during infertility work-up, although it is sometimes unnecessary. This review highlights when laparoscopic intervention should be used in women undergoing assisted reproductive technology cycles.

RECENT FINDINGS

There is no evidence for an increase in pregnancy rates in assisted reproductive technology cycles following surgical treatment of pelvic adhesions or endometriosis with laparoscopy. If the patient has bilateral visible hydrosalpinges, laparoscopy may be an option for evaluation of the tubes and treatment with salpingectomy in order to enhance the chance of pregnancy before commencing an assisted reproductive technology cycle. Laparoscopic ovarian drilling before assisted reproductive technology may be considered a therapeutic option in polycystic ovary disease patients who previously had severe ovarian hyperstimulation syndrome. Finally, laparoscopy may be useful in replacing the transposed ovaries to their original sites in the pelvic cavity in previously treated cancer patients so that monitoring of the controlled ovarian hyperstimulation and the oocyte aspiration would be much easier during the assisted reproductive technology cycles.

SUMMARY

Laparoscopy should be considered before assisted reproductive technology cycles if the procedure diagnoses and treats a pelvic pathology at the same time and if laparoscopic intervention increases the chance of pregnancy following these cycles.

Hydrosalpinx and assisted reproduction: options and rationale for treatment

Salpingoscopy during laparoscopy yields the best prognosis in patients with hydrosalpinx. It has been demonstrated that in-vitro fertilization (IVF) patients with hydrosalpinx have decreased pregnancy rates as compared with control individuals. If a patient with hydrosalpinx is to be treated with IVF, then the communication between the uterine tube and the uterine cavity should be blocked via salpingectomy or proximal tubal ligation, with or without distal tubal fenestration. This is because there is evidence that hydrosalpinx, especially when it is bilateral and visible by ultrasonography, impacts negatively on pregnancy and implantation rates after IVF cycles.
