Recurrence of hydrosalpinges after cuff neosalpingostomy in a poor prognosis population

The current and future state of surgery in reproductive endocrinology

PURPOSE OF REVIEW

The last decade has witnessed a radical change in the field of reproductive surgery. The increasing success of in-vitro fertilization (IVF) has caused a huge shift in emphasis with many downstream consequences. This review outlines the changes and provides insight into the future of reproductive surgery.

RECENT FINDINGS

With compelling evidence that IVF overcomes the detrimental effects of endometriosis on infertility and with two new oral medications available for management of endometriosis, momentum is shifting towards nonsurgical management of endometriosis. There is increasing recognition that except for submucous myomas, other myomas are unlikely to affect fertility and miscarriage. This, in addition to many emerging alternative modalities for management of myomas (oral GnRH antagonists, radiofrequency ablation), is likely to further decrease classic myomectomies but provide alternative, less invasive options. Caesarean scar defects have been recognized as having significant reproductive consequences and surgical management has become the standard of care. Fallopian tubes are now implicated in development of ovarian cancer, and as a result, salpingectomies are being performed in lieu of tubal ligations. Tubal anastomosis will soon become a historical surgery. Division of uterine septum remains controversial, and a clear answer will remain elusive. Uterine transplant is the single most significant advance in reproductive surgery in the past century.

SUMMARY

Reproductive surgery is evolving with the times. Although some surgical techniques will become historical, others will become mainstream.

Hydrosalpinx - Salpingostomy, salpingectomy or tubal occlusion

Tubal factors account for approximately 25% of cases of infertility, and the most severe manifestation of tubal disease is hydrosalpinx, accounting for 10-30% of tubal diseases. Hydrosalpinx is a distension or dilatation of the fallopian tube in the presence of a distal tubal occlusion, and the most common cause is pelvic inflammatory disease. Women with hydrosalpinges have lower implantation and pregnancy rates in assisted reproductive technology (ART), due to a combination of mechanical and chemical factors thought to disrupt the endometrial environment. Current guidance is removal of the tube by salpingectomy (preferably laparoscopically) before IVF treatment. Salpingostomy, or distal tubal plastic surgery in the management of hydrosalpinx, is an alternative for women desiring natural conception, although ectopic pregnancy rates as high as 10% have been reported. Proximal tubal occlusion with Essure^® devices placed hysteroscopically can be considered particularly in cases of distorted pelvic anatomy or pelvic adhesions making abdominal surgery complex. However, low clinical pregnancy and live birth rates have been reported with the use of these devices before IVF. In this review, we discuss salpingostomy, salpingectomy and tubal occlusion as possible management options for the reproductive women with hydrosalpinx.

Tubal restorative surgery for hydrosalpinges in women due to in vitro fertilization

OBJECTIVE

The study was carried out to clarify the IVF outcome after laparoscopic neosalpingostomy for infertile patients affected by hydrosalpinx stage III.

MATERIALS AND METHODS

From January 2010 to June 2015, 91 subjects of hydrosalpinx stage III were treated in out center by laparoscopic surgery before IVF cycle. 43 underwent neosalpingostomy (group 1) and the remaining 48 underwent salpingestomy (group 2). We compared these patients and their IVF outcomes after two different surgical techniques.

RESULTS

There were no significant differences between the two groups, except a higher number of patients with bilaterial hydrosalpinges was noted in the neosalpingostomy group (79.1% vs. 56.3%, respectively). 25 patients with neosalpingostomy and 29 with salpingectomy achieved pregnancy by IVF. The ongoing pregnancy rate per cycle in group 1 and group 2 was 51.1 and 47.2%, respectively. Two cases of ampullary ectopic pregnancies were noted in group 1 and one case of right tube interstitial pregnancy in group 2. No significant difference was observed in live birth rate between the groups (48.9% vs. 45.3%, respectively).

CONCLUSIONS

The outcomes of IVF after neosalpingostomy were matchable with salpingectomy. For patients desire to preserve fallopian tubes, we recommend laparoscopic neosalpingostomy as an alternative choice to manage moderate hydrosalpinx before IVF.

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.

STUDY FUNDING/COMPETING INTERESTS

No external funding was either sought or obtained for this study. The authors have no competing interests to declare.

Clinical application of operative hysteroscopy in treatment of complex hydrosalpinx prior to IVF

BACKGROUND

In vitro fertilization and embryo transfer (IVF-ET) is the best option for patients with hydrosalpinx. However, if hydrosalpinges is not pre-treated, the therapeutic outcomes of IVF-ET would be compromised.

OBJECTIVE

This study aims to investigate the safety and effects of operative hysteroscopy in the treatment of patients with hydrosalpinx prior to IVF-ET, who were not indicated for laparotomy due to extensive pelvic adhesion.

MATERIALS AND METHODS

The study analyses retrospectively data from 10 women with hydrosalpinx, who were unable to undergo laparotomy due to extensive pelvic adhesion and treated by operative hysteroscopy prior to IVF-ET, and was assessed the effects and safety of the procedure.

RESULTS

Postoperative Hystero-salpingography demonstrated complete tubal occlusion of the diseased side in all cases. Being applied with IVF-ET for fertility after their hysteroscopy operation, 5 out of 10 patients acquired clinical pregnancy.

CONCLUSION

Hysteroscopic tubal occlusion of the proximal part of the hydrosalpinx can effectively prevent the hydrops backflow to endometrial cavity and benefit subsequent implantation in the course of assisted reproduction without significant complications.

Isolated fallopian tube torsion with partial hydrosalpinx in a premenarcheal girl: a case report

INTRODUCTION

Isolated fallopian tube torsion as a complication of a preexisting hydrosalpinx is a rare finding in pediatric patients. The obvious rarity of this condition, its subtle diagnostic features and dissonant previous reporting about the appropriate therapeutic approach according to age, future conception capacity and potential complications of possible pregnancies make the decision about which surgical approach to use very difficult. In this report, we describe the case of a patient with such a presentation and review the literature. Very few similar reports of neosalpingostomy in pediatric patients have been published to date.

CASE PRESENTATION

In our present report, we describe the case of an 11-year-old Caucasian prepubertal girl who presented to our hospital with complaints of abdominal pain in the right lower quadrant, nausea and vomiting. The diagnostic workup led us to conclude that she had a torsion of the right ovary, which was cystically altered. Exploratory surgery revealed a partial hydrosalpinx and consecutive isolated torsion of the fimbrial part. The proximal isthmic part of the fallopian tube was intact and vital. Restorative surgery was performed to create a neosalpingostomy on the viable isthmic part of the tube and remove the cystic and twisted fimbrial and infundibular parts.

CONCLUSION

The surgical procedure described in this report is technically simple and feasible, but leaves doubts about the final outcome.

Assisted reproductive techniques

Assisted reproductive technologies (ART) encompass fertility treatments, which involve manipulations of both oocyte and sperm in vitro. This chapter provides a brief overview of ART, including indications for treatment, ovarian reserve testing, selection of controlled ovarian hyperstimulation (COH) protocols, laboratory techniques of ART including in vitro fertilization (IVF), and intracytoplasmic sperm injection (ICSI), embryo transfer techniques, and luteal phase support. This chapter also discusses potential complications of ART, namely ovarian hyperstimulation syndrome (OHSS) and multiple gestations, and the perinatal outcomes of ART.

Redefining reproductive surgery

With the availability of and improvements in in vitro fertilization (IVF), the role of reproductive surgery has been questioned. Yet, the scope of reproductive surgery today is much larger than in the past. Hysteroscopic correction of intrauterine disease is an important endoscopic procedure in women with infertility. Evidence suggests that correction of intrauterine disease is often followed by spontaneous pregnancy and improved IVF outcome. Hysteroscopic examination should be considered after 1 failed IVF. Today, it is clear that removal of the hydrosalpinx leads to a higher IVF-related live birth rate. The procedure should be performed thoroughly without compromising the ovarian blood supply. The IVF pregnancy rate is not affected by the presence of ovarian endometriomas, and small endometriomas need not be removed; however, large and symptomatic endometriomas that interfere with oocyte retrieval should be excised. When excision of the cyst wall is difficult, fenestration and ablation should be considered. This might lead to an increased recurrence rate, but is associated with less interference of the ovarian reserve. Although the role of reproductive surgery as primary treatment for tuboperitoneal infertility is limited, it has an important role in enhancing the outcome of IVF treatment and in preservation of fertility. Surgical preservation of fertility consists of ovarian suspension, ovarian excision for cryopreservation, and ovarian tissue transplantation.

Is surgical repair of the fallopian tubes ever appropriate?

The overall median prevalence of infertility, defined as no conception after more than 12 months of unprotected intercourse with the husband or cohabiting partner in women aged 15 to 44 years, is approximately 9%. About 25% to 33% of female infertility is the result of tubal disease and endometriosis. In view of very successful alternative treatment of tubal factor infertility, the surgical repair of the fallopian tubes is all but obsolete and has been replaced with assisted reproductive technology. This article reviews situations in which surgical repair of the fallopian tubes may facilitate conception.
