A European survey on treatment of hydrosalpinges in infertile women on behalf of the European Society for Gynaecological Endoscopy (ESGE) Special Interest Group (SIG) on Reproductive Surgery

A questionnaire-based survey was conducted among members of the European Society for Gynaecological Endoscopy (ESGE), with the aim of increasing awareness of the diagnosis and surgical treatment of tubal disease as an alternative to in-vitro fertiliszation (IVF). Seventeen participants (34%) occasionally used a test for prediction of the ovarian reserve before surgery, and the most commonly used test was anti-mullerian hormone assay (39/50; (80%). Laparoscopy was the preferred method for staging tubal disease (43/50; 86%).Thirty-seven (76%) participants always performed salpingectomy or tubal occlusion before the first IVF attempt. Thirty (60%) of the gynaecological surgeons considered the outcome with tubal surgery and IVF to be similar in mild tubal disease, whereas for severe disease, 31/50 (62%) felt that surgery had worse outcome. Among other factors to be considered in choosing a strategy for treating infertility, 20/50 (40%) of respondents listed the stage of disease. The findings of this survey suggest that first-line treatment for women younger than 35 years old with minor tubal pathology, is tubal surgery. IVF appears to be offered if there are other infertility factors, if the patient is >38 years old and if moderate to severe tubal disease is present.

Changes in the incidence and uptake of reproductive surgery versus in vitro fertilisation in Australia between 2001 and 2015: A population-based study

OBJECTIVE

Improvements in success rates of assisted reproduction led to predictions that infertility surgery in both women and men would become extinct in developed countries. We sought to identify the changes in reproductive surgery that occurred between 2001 and 2015 to determine whether these predictions have been accurate.

DESIGN

The Australian Institute of Health and Welfare (AIHW) national procedural dataset and the Australian Medicare Benefits Scheme (MBS) claims database were searched for procedure data for male and female reproductive surgery and assisted reproduction from January 2001 to December 2015. The denominators were based on annual point estimates of the total population aged 25-44 years (female) and 25-55 years (male) from the Australian Bureau of Statistics (ABS). This dataset provides procedures undertaken but not their indications.

RESULTS

Over the study period the incidence of tubal surgery fell by 66%, vasectomy reversal by 33%, and surgical varicocoelectomy by 50%. In contrast, the rate of hysteroscopic myomectomy increased by 48%, hysteroscopic septoplasty by 125%, and laparoscopy for severe endometriosis increased by 84%. In vitro fertilisation oocyte retrievals increased by 90%. The rate of abdominal myomectomy was unchanged.

CONCLUSION

Fertility surgery is not dead but has evolved.

Fallopian tube catheterization in the treatment of proximal tubal obstruction: a systematic review and meta-analysis

Study question

What is the chance of clinical pregnancy when fallopian tube catheterization is used for proximal tubal obstruction?

Summary answer

The pooled clinical pregnancy rate of tubal catheterization after proximal tubal obstruction is 27% (95% CI 25-30%).

What is known already

Restoring fallopian tube patency by performing tubal catheterization has fallen out of favour since the increased availability of IVF. Our study is the first systematic review and meta-analysis to investigate reproductive outcomes following tubal catheterization for proximal tubal obstruction.

Study design, size, duration

We undertook a systematic review and meta-analysis of 27 observational studies consisting of 1720 patients undergoing tubal catheterization for proximal tubal obstruction, who attempted to conceive naturally after the procedure.

Participants/materials, setting, methods

Systematic literature searches were performed in MEDLINE, EMBASE and the Cochrane Central Register of Controlled Trials. A total of 2195 titles and abstracts were reviewed. Only studies that reported outcomes when tubal catheterization was performed with no other tubal surgery were included. Twenty-seven cohort studies matched the inclusion criteria for the meta-analysis.

Main results and the role of chance

The meta-analysis showed a pooled clinical pregnancy rate of 27% (95% CI 25-30%) after the use of tubal catheterization for unilateral or bilateral proximal tubal obstruction (27 studies, 1556 patients). In women with bilateral obstruction (14 studies, 617 patients), the clinical pregnancy rate was 27% (95% CI 23-32%). Our meta-analysis demonstrated that the pooled cumulative clinical pregnancy rates were 22.3% (95% CI 17.8-27.8%) at 6 months, 25.8% (95% CI 21.1-31.5%) at 9 months, 26.4% (95% CI 23.0-30.2%) at 12 months, 26.0% (95% CI 22.8-29.7%) at 18 months, 27.0% (95% CI 24.0-30.5%) at 24 months, 27.9% (95% CI 24.9-31.3%) at 36 months and 28.5% (95% CI 25.5-31.8%) at 48 months. The pooled live birth rate (14 studies, 551 patients) was 22% (95% CI 18-26%). The pooled ectopic pregnancy rate (27 studies, 1556 patients) was 4% (95% CI 3-5%). The included studies scored satisfactorily on the Newcastle-Ottawa quality assessment scale.

Limitations, reasons for caution

The pooled clinical pregnancy rate after tubal catheterization was found to be almost comparable to that after IVF. However, included studies were small, non-comparative series with significant clinical heterogeneity in population characteristics, follow-up and surgical equipment, technique and experience.

Wider implications of the findings

These findings suggest fallopian tube catheterization as an alternative strategy to IVF in patients presenting with proximal tubal obstruction. Further research should focus on comparing different surgical techniques of fallopian tube catheterization with IVF and provide cumulative reproductive outcomes over long-term follow-up.

Salpingostomy in the treatment of hydrosalpinx: a systematic review and meta-analysis

STUDY QUESTION

What is the chance of natural conception when salpingostomy is used to treat hydrosalpinx?.

SUMMARY ANSWER

The natural clinical pregnancy rate following salpingostomy is 27%, in the hands of experienced surgeons who publish their results.

WHAT IS KNOWN ALREADY

Tubal surgery is not commonly offered for women with hydrosalpinges since the advent of assisted conception treatment. This is the first systematic review to investigate natural conception rates following salpingostomy in the treatment of hydrosalpinx.

STUDY DESIGN, SIZE, DURATION

A systematic review and meta-analysis of 22 observational studies encompasses 2810 patients undergoing salpingostomy and attempting natural conception.

PARTICIPANTS/MATERIALS, SETTING, METHODS

Literature searches were conducted to retrieve observational studies which reported salpingostomy for hydrosalpinx. Databases searched included MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials and CINAHL, with no language restriction. Only studies that focused on salpingostomy (rather than other tubal conserving surgeries) for the treatment of hydrosalpinx were included. A total of 22 studies matched the inclusion criteria.

MAIN RESULTS AND THE ROLE OF CHANCE

The pooled natural clinical pregnancy rate from the 22 observational studies (including 2810 patients) was 27% (95% confidence interval (CI): 25-29%) after salpingostomy was performed for hydrosalpinx. The cumulative clinical pregnancy rates were 8.7% (95% CI: 6.6-11.5%) at 6 months, 13.3% (95% CI: 10.6-16.7%) at 9 months, 20.0% (95% CI: 17.5-22.8%) at 12 months, 21.2% (95% CI: 18.6-24.1%) at 18 months and 25.5% (95% CI: 22.2-29.4%) at 24 months after salpingostomy. The pooled live birth rate (10 studies, 1469 patients) was 25% (95% CI: 22-28%) after salpingostomy was performed for hydrosalpinx. The pooled ectopic pregnancy rate (19 studies, 2662 patients) was 10% (95% CI: 9-11%). The pooled miscarriage rate (seven studies, 924 patients) was 7% (95% CI: 6-9%). The included studies scored well on the Newcastle Ottawa quality assessment scale.

LIMITATIONS, REASONS FOR CAUTION

Strict inclusion criteria were used in the conduct of the systematic review. However, the studies included are clinically heterogeneous in many aspects including patient characteristics, surgical technique and duration of follow-up after salpingostomy.

WIDER IMPLICATIONS OF THE FINDINGS

The findings of this systematic review suggest that salpingostomy is an alternative treatment strategy to tubal clipping or salpingectomy in patients presenting to fertility services with hydrosalpinx. Further prospective, large and high quality studies are needed to identify the subpopulation that would most benefit from tube conserving surgery.

Economic evaluation of infertility treatment for tubal disease

PURPOSE

The number of published studies comparing cost-effectiveness of tubal surgery and IVF treatment is limited, in part because of the difficulties of conducting randomized trials, given that IVF is now a clinically accepted treatment and the decision to offer surgery or IVF is often dictated by the severity of the tubal disease and by the availability of the methods. The aim of this study was to compare the costs of our policy of offering tubal surgery to patients with mild or moderate tubal disease with the cost of offering IVF to these and severe tubal disease.

METHODS

In this retrospective cohort study patients with tubal pathology as the sole reason for their infertility were included: 61 patients in the tubal surgery group and 464 patients in the IVF group. The delivery rates and costs per delivery were compared.

RESULTS

Delivery rates were 28% in the tubal surgery group within 2 years of follow-up and 52% in the IVF group that involved up to three cycles of treatment. This economic evaluation demonstrated only small differences in the average cost when considering the cost per delivery.

CONCLUSIONS

With a policy involving strict selection of patients, tubal surgery will continue to have a role in the treatment of infertility.
