Role of tubal surgery in the era of assisted reproductive technology: a committee opinion

[First-line management of infertile couple. Guidelines for clinical practice of the French College of Obstetricians and Gynecologists 2022]

OBJECTIVE

To update the 2010 CNGOF clinical practice guidelines for the first-line management of infertile couples.

MATERIALS AND METHODS

Five major themes (first-line assessment of the infertile woman, first-line assessment of the infertile man, prevention of exposure to environmental factors, initial management using ovulation induction regimens, first-line reproductive surgery) were identified, enabling 28 questions to be formulated using the Patients, Intervention, Comparison, Outcome (PICO) format. Each question was addressed by a working group that had carried out a systematic review of the literature since 2010, and followed the Grading of Recommendations Assessment, Development and Evaluation (GRADE®) methodology to assess the quality of the scientific data on which the recommendations were based. These recommendations were then validated during a national review by 40 national experts.

RESULTS

The fertility work-up is recommended to be prescribed according to the woman's age: after one year of infertility before the age of 35 and after 6months after the age of 35. A couple's initial infertility work-up includes a single 3D ultrasound scan with antral follicle count, assessment of tubal permeability by hysterography or HyFOSy, anti-Mullerian hormone assay prior to assisted reproduction, and vaginal swabbing for vaginosis. If the 3D ultrasound is normal, hysterosonography and diagnostic hysteroscopy are not recommended as first-line procedures. Chlamydia trachomatis serology does not have the necessary performance to predict tubal patency. Post-coital testing is no longer recommended. In men, spermogram, spermocytogram and spermoculture are recommended as first-line tests. If the spermogram is normal, it is not recommended to check the spermogram. If the spermogram is abnormal, an examination by an andrologist, an ultrasound scan of the testicles and hormonal test are recommended. Based on the data in the literature, we are unable to recommend a BMI threshold for women that would contraindicate medical management of infertility. A well-balanced Mediterranean-style diet, physical activity and the cessation of smoking and cannabis are recommended for infertile couples. For fertility concern, it is recommended to limit alcohol consumption to less than 5 glasses a week. If the infertility work-up reveals no abnormalities, ovulation induction is not recommended for normo-ovulatory women. If intrauterine insemination is indicated based on an abnormal infertility work-up, gonadotropin stimulation and ovulation monitoring are recommended to avoid multiple pregnancies. If the infertility work-up reveals no abnormality, laparoscopy is probably recommended before the age of 30 to increase natural pregnancy rates. In the case of hydrosalpinx, surgical management is recommended prior to ART, with either salpingotomy or salpingectomy depending on the tubal score. It is recommended to operate on polyps>10mm, myomas 0, 1, 2 and synechiae prior to ART. The data in the literature do not allow us to systematically recommend asymptomatic uterine septa and isthmoceles as first-line surgery.

CONCLUSION

Based on strong agreement between experts, we have been able to formulate updated recommendations in 28 areas concerning the initial management of infertile couples.

Where Microsurgical Tubal Reanastomosis Stands in the In vitro Fertilization Era

Among various options of contraception, bilateral tubal ligation (BTL) remains the most frequently used method for women worldwide even at present. However, up to 30% of those who undergo BTL eventually change their minds and wish to conceive again for a variety of reasons, such as a change in marital status or simply wanting more children. In this case, we can either approach it surgically with tubal re-anastomosis (TA) or by in vitro fertilization (IVF)-embryo transfer. Despite the many advantages of TA which lead the American Society of Reproductive Medicine Committee Opinion to recommend it as the primary choice of treatment in posttubal ligation infertility in 2012, IVF is widely being chosen as the first-line treatment nowadays. This study will review the efficacy of TA in various aspects, including pregnancy rate, cost-effectiveness, feasibility, and accessibility, based on review of the literature and our experience. Through this study, we intend to provide a basis for gynecologists to consider TA as the first option in women who wish to conceive again after BTL in this day and age of IVF.

Comparative efficacy of acupuncture-related interventions for tubal obstructive infertility: A systematic review and Bayesian meta-analysis of randomized controlled trials

BACKGROUND

Tubal obstructive infertility (TOI) is a challenging condition affecting many women worldwide. Acupuncture and herbal medicine have emerged as potential therapeutic options for enhancing fertility outcomes in these patients. However, the evidence regarding their efficacy remains inconclusive, necessitating a comprehensive systematic review and meta-analysis.

METHOD

Computer searches were conducted in PubMed, Cochrane, Embase, Web of Science, China National Knowledge Infrastructure (CNKI), VIP Information, Wanfang Database, and China Biology Medicine (CBM) databases to retrieve relevant literature on the efficacy and safety of acupuncture and related therapies for the treatment of tubal obstructive infertility. The search period extended from the inception of the databases to December 2022. Two researchers independently screened the literature based on strict inclusion criteria, extracted relevant data, and utilized Cochrane Collaboration tools and the Jadad scale to comprehensively assess the quality of the included studies. Subsequently, pairwise meta-analysis and network meta-analysis were performed using statistical software such as StataSE and Rstudio, and graphical representations were generated to present the results.

RESULT

The network meta-analysis included 1580 articles, with 23 meeting the criteria. These studies involved 2355 patients and explored 13 intervention measures. Acupuncture-related therapies outperformed control interventions in improving pregnancy rates, tubal patency rates, and overall effectiveness while demonstrating a lower incidence of adverse events. EA+CHM was identified as the most effective for pregnancy rates, MOX for tubal patency rates, and MOX+AP for overall effectiveness. The safety profile of acupuncture-related interventions was acceptable. These findings support acupuncture-related therapies as effective and safe options for tubal obstructive infertility management. Further high-quality research is needed to validate and expand upon these results.

CONCLUSION

These findings offer novel treatment strategies for acupuncture-related interventions, providing practitioners with evidence-based guidance. Addressing limitations through future research is crucial, including diverse literature, emphasizing higher-quality RCTs, and exploring a broader range of interventions with long-term follow-up data. Systematic assessment of adverse events, standardized techniques, and robust ranking methods should be considered.

Comparisons of different treatment outcomes in IVF/ET patients with hydrosalpinx: a retrospective study

AIMS

To explore suggestions for clinicians on the most effective treatment for hydrosalpinx undergoing IVF-ET.

MATERIALS AND METHODS

We reviewed 936 women with hydrosalpinx and 6715 tubal infertile women without hydrosalpinx who underwent IVF/ICSI between January 2014 and August 2019 in our center. Hydrosalpinx patients received different treatments including laparoscopic surgery (only salpingectomy and proximal tubal occlusion/ligation were included), ultrasonic-guided aspiration and hysteroscopic tubal occlusion. Outcomes were analyzed by One-way ANOVA, Chi-Square test and logistic regression.

RESULTS

The live birth rate (LBR) of laparoscopic surgery was significantly higher compared with hydrosalpinx aspiration (48.3% vs 39.6%, p = .024). The cumulative live birth rate (CLBR) of subsequent laparoscopic surgery was significantly higher compared with subsequent hysteroscopic occlusion (65.1% vs 34.1%, p = .001) and no subsequent treatment (65.1% vs 44.9%, p  <  .005). Subsequent laparoscopic surgery significantly improved the CLBR of hydrosalpinx patients who received ultrasonic-guided aspiration and didn't get clinical pregnancy in fresh cycles (Odds Ratio (OR) =1.875; 95%CI = 1.041-3.378, p = .036).

CONCLUSIONS

Laparoscopic surgery leads to significantly higher LBR than ultrasonic-guided aspiration and significantly higher CLBR than hysteroscopic occlusion and no treatment.

Tubal Pathologies and Fertility Outcomes: A Review

Anomalies of the fallopian tubes represent one of the most significant elements that might contribute to reproductive issues. They can be inherited or acquired; they are among the most important problems of the profession. Although there is much discussion regarding which therapies for each tubal disease are the most effective and result in the best long-term reproductive outcomes. During the evaluation of an infertile couple, certain anomalies of the fallopian tubes are frequently discovered. These abnormalities were thought, for a long time, to not have an influence on fertility; however, in recent years, researchers have discovered that they seem to play a crucial role in fertility problems. Couples in industrialized countries are postponing childbearing, which raises the risk of women developing tubal diseases before they are ready to become pregnant. These disorders may have a negative impact on a woman's ability to get pregnant. The goals of this study are to conduct research to gain a deeper understanding of the recent advancements that have been made in the field of tubal diseases and to carry out an evaluation of the medical conducts that have the best fertility outcomes. We searched both Medline and PubMed, paying special attention to the most relevant articles that have been added to either database over the course of the last six years.

Restoring tubal patency with laparoscopic tubocornual anastomosis

OBJECTIVE

To assess the technical feasibility of laparoscopic tubocornual anastomosis (TCA) at restoring tubal patency in patients with proximal tubal occlusions.

MATERIALS AND METHODS

A retrospective analysis of fourteen females with identified proximal tubal occlusions seeking to restore their tubal patency in a university-affiliated tertiary hospital between 2011 and 2018. Tubal patency within one year after the surgery was evaluated.

RESULTS

The patients had a mean age of 34.0 ± 3.6 years old, median parity of 1 child, and mean BMI of 23.0 ± 5.2 kg/m². Of the fourteen patients, two (14.3%) received bilateral TCA, eight (57.1%) received only unilateral TCA, and four (28.6%) received TCA on one side and tubal anastomosis on the other. The operative time was 126.4 ± 37.9min for unilateral procedure and 201.0 ± 1.4 min for bilateral anastomoses. Postoperative hysterosalpingogram (HSG) demonstrated a patency rate of 64.2% at the TCA sites. Two ectopic pregnancies were reported thereafter.

CONCLUSION

This preliminary series demonstrates that laparoscopic TCA is technically feasible and provides promising results for patients with proximal tubal occlusions hoping to restore their tubal function in order to conceive naturally. A larger prospective series is mandatory to establish its significance and application in clinical practices. Notably, infertile patients without surgically correctable factors are not suitable for this procedure.

Transcutaneous electrical acupoint stimulation improves endometrial receptivity resulting in improved IVF-ET pregnancy outcomes in older women: a multicenter, randomized, controlled clinical trial

OBJECTIVE

To examine the effects and mechanisms of transcutaneous electrical acupoint stimulation (TEAS) on pregnancy outcomes in women undergoing in vitro fertilization (IVF)-embryo transfer (ET).

DESIGN, SETTING, AND PARTICIPANTS

This efficacy study was a multicenter, randomized, controlled clinical trial (RCT) in women receiving IVF-ET. The mechanistic study was a single-center RCT.

INTERVENTIONS

The participants received TEAS vs. no TEAS treatment.

MAIN OUTCOME MEASURES

In the efficacy study, the primary outcomes were the rates of clinical pregnancy, embryo implantation, and live birth. In the mechanistic study, sex hormones and endometrial protein expression were examined.

RESULTS

Ultimately, 739 participants were enrolled (367 and 372 in the TEAS and control groups, respectively). The clinical pregnancy rate was higher in the TEAS group than in the controls (55.1% vs. 46.7%, P = 0.03). There were no significant differences in embryo implantation, biochemical pregnancy, and live birth rates between the two groups (all P > 0.05) in the study population. In women > 35 years, the clinical pregnancy rates, embryo implantation rates and live birth rates in the TEAS and control groups were 48.9% vs. 23.7% (P = 0.004),30.8 vs. 13.9% (P = 0.001) and 34.0% vs. 19.7% (P = 0.06) respectively. In the mechanistic study with 120 participants, on the theoretical embryo implantation day, better developed endometrial pinopodes, elevated endometrial integrin α1β1/αVβ3, leukemia inhibitory factor, and elevated serum progesterone levels were found in the TEAS group compared with controls.

CONCLUSION

TEAS significantly improved the clinical pregnancy rate in women undergoing IVF-ET, especially in women of older age. It might be due to improved endometrial receptivity.

Robot-Assisted Tubal Reanastomosis after Sterilization: A Choice for Family Planning

A variety of procedures have been used for family planning. One of these is sterilization surgery, which can be reversed by a tubal reanastomosis. In the present report, we compare Robot-assisted tubal reanastomosis sterilization with other methods of family planning and discuss factors related to the choice of the approach. The keywords used for the electronic search in PubMed were family planning, sterilization, Robot-assisted, tubal reanastomosis, depression, and regret. The decision in favor of or against sterilization surgery has been a sensitive issue for several years. Robot-assisted technology is a modern and precise approach. It has contributed to the flexibility of the decision between sterilization and its reversal through tubal reanastomosis, as well as enhanced the success rate of the surgery. Based on our analysis of the published literature, we believe that Robot-assisted tubal anastomosis is the optimum approach. However, to ensure the quality of health care, the surgeon must be well trained, well versed with the anatomy of the fallopian tubes, and thoroughly informed on the psychological impact of family planning.

The Performance of Transvaginal Two-Dimensional Fundamental Sonosalpingography Combined with Saline Infusion Pelvic Sonosalpingography for Assessing Fimbrial Part's Morphology and Function of the Fallopian Tubes

OBJECTIVES

The purpose of this study was to evaluate the diagnostic efficacy of transvaginal two-dimensional fundamental sonosalpingography (2D-FS) combined with saline infusion pelvic sonosalpingography (SIPS) for assessing fimbrial part's morphology and function of the fallopian tubes.

METHODS

One hundred and sixty-nine cases underwent 2D-FS combined with SIPS. Among them, 18 cases received laparoscopy and dye test (LDT) within 3 months after the examination and the results were regarded as reference standard.

RESULTS

Excluding proximal or middle segment obstructed tubes, the remaining fimbrial parts' display rate by using 2D-FS combined with SIPS was 75.1%. According to the ultrasonic appearance, the fimbrial parts were classified into 4 types: normal, abnormal, suspected abnormal, and unclassifiable. Normal fimbrial parts accounted for 73.8% when the tubes were patent; abnormal fimbrial parts accounted for 74.1% when the tubes were partial obstructed; all became abnormal when the tubes were distal complete obstructed. The fimbrial parts which had been classified by 2D-FS combined with SIPS were compared with LDT further. This combination's accuracy (ACC), sensitivity (SEN), specificity (SPE), positive predictive value (PPV), negative predictive value (NPV), and Youden's index (YI) were 86.4, 87.5, 85.7, 77.8, 92.3, and 0.73%, respectively. The result of consistency analysis showed the combination was essentially consistent with LDT result (Kappa = 0.713).

CONCLUSION

2D-FS combined with SIPS can be a preferred method for assessment of the fimbrial part's morphology and function, with its advantages of non-invasive, intuition, and accuracy. This combination could provide an objective imaging basis for choosing clinical treatment strategies and predicting prognosis.

A review of the pathophysiology of recurrent implantation failure

Implantation is a critical step in human reproduction. The success of this step is dependent on a competent blastocyst, receptive endometrium, and successful cross talk between the embryonic and maternal interfaces. Recurrent implantation failure is the lack of implantation after the transfer of several embryo transfers. As the success of in vitro fertilization has increased and failures have become more unacceptable for patients and providers, the literature on recurrent implantation failure has increased. While this clinical phenomenon is often encountered, there is not a universally agreed-on definition-something addressed in an earlier portion of this Views and Reviews. Implantation failure can result from several different factors. In this review, we discuss factors including the maternal immune system, genetics of the embryo and parents, anatomic factors, hematologic factors, reproductive tract microbiome, and endocrine milieu, which factors into embryo and endometrial synchrony. These potential causes are at various stages of research and not all have clear implications or immediately apparent treatment.

Conventional Laparoscopy Is the Better Option for Tubal Sterilization Reversal: A Closer Look at Tubal Reanastomosis

Background: Permanent sterilization is one of the most common methods of birth control in the United States and around the world. A small subset of women will regret their decision and desire future fertility. For these women, the options include in vitro fertilization (IVF) or surgical reversal. Surgical reversal, specifically via tubal reanastamosis, is an important choice to consider. Surgical reversal can be accomplished via three different general approaches including laparotomy, conventional laparoscopy, and robot-assisted approaches. Unfortunately, surgical reversal is becoming a lost art.

Objective: To compare and contrast pregnancy success rates, ectopic pregnancy rates, and cost between the surgical methods and IVF.

Methods: We conducted a literature review via Pubmed with keywords as listed below.

Conclusion: Laparoscopic tubal reanastomosis is the best approach for women <40 years of age due to pregnancy outcomes that are comparable to other methods, cost effectiveness, and favorable safety profile of minimally invasive surgery.

Diagnosis and Management of Infertility: A Review

IMPORTANCE

In the US, approximately 12.7% of reproductive age women seek treatment for infertility each year. This review summarizes current evidence regarding diagnosis and treatment of infertility.

OBSERVATIONS

Infertility is defined as the failure to achieve pregnancy after 12 months of regular unprotected sexual intercourse. Approximately 85% of infertile couples have an identifiable cause. The most common causes of infertility are ovulatory dysfunction, male factor infertility, and tubal disease. The remaining 15% of infertile couples have "unexplained infertility." Lifestyle and environmental factors, such as smoking and obesity, can adversely affect fertility. Ovulatory disorders account for approximately 25% of infertility diagnoses; 70% of women with anovulation have polycystic ovary syndrome. Infertility can also be a marker of an underlying chronic disease associated with infertility. Clomiphene citrate, aromatase inhibitors such as letrozole, and gonadotropins are used to induce ovulation or for ovarian stimulation during in vitro fertilization (IVF) cycles. Adverse effects of gonadotropins include multiple pregnancy (up to 36% of cycles, depending on specific therapy) and ovarian hyperstimulation syndrome (1%-5% of cycles), consisting of ascites, electrolyte imbalance, and hypercoagulability. For individuals presenting with anovulation, ovulation induction with timed intercourse is often the appropriate initial treatment choice. For couples with unexplained infertility, endometriosis, or mild male factor infertility, an initial 3 to 4 cycles of ovarian stimulation may be pursued; IVF should be considered if these approaches do not result in pregnancy. Because female fecundity declines with age, this factor should guide decision-making. Immediate IVF may be considered as a first-line treatment strategy in women older than 38 to 40 years. IVF is also indicated in cases of severe male factor infertility or untreated bilateral tubal factor.

CONCLUSIONS AND RELEVANCE

Approximately 1 in 8 women aged 15 to 49 years receive infertility services. Although success rates vary by age and diagnosis, accurate diagnosis and effective therapy along with shared decision-making can facilitate achievement of fertility goals in many couples treated for infertility.

Evaluation of the efficacy of traditional Chinese medicine for the reproductive and pregnancy outcomes in women with endometriosis: A nationwide population-based study

OBJECTIVE

Patients with endometriosis may seek traditional Chinese medicine (TCM) to help them conceive. The present study aims to evaluate the effects of TCM on reproductive and pregnancy outcomes in patients with endometriosis.

MATERIALS AND METHODS

The patients with endometriosis taken from the National Health Insurance (NHI) research database between 2000 and 2012 were divided into two cohorts based on the use of TCM treatment. The two cohorts were matched by age and comorbidities and followed up until a new diagnosis of infertility, ectopic pregnancy, or miscarriage. Multivariable Cox proportional hazards models were used to evaluate the hazard ratio (HR) of reproductive and pregnancy outcomes.

RESULTS

A total of 5244 patients with endometriosis were analyzed, including 1748 TCM users and 3496 matched control subjects. The proportion of infertility was higher in TCM users than in non-TCM users (adjusted hazard ratio [HR]: 1.34, 95% confidence interval [CI]: 1.13-1.60). However, there was no significant difference in the proportion of ectopic pregnancies between TCM users and non-TCM users (adjusted HR: 0.82, 95% CI: 0.60-1.13). There was no significant difference in the proportion of miscarriages between TCM users and non-TCM users (adjusted HR: 1.23, 95% CI: 0.95-1.61).

CONCLUSION

TCM treatment showed insignificant efficacy in decreasing the risk of ectopic pregnancy and miscarriage in patients with endometriosis.

Effectiveness of laparoscopic tubal anastomosis in tubal occlusion patients after laparoscopic salpingostomy for tubal pregnancy

OBJECTIVE

To evaluate the effectiveness of laparoscopic tubal anastomosis for tubal occlusions associated with infertility in patients with previous laparoscopic salpingostomy for ectopic pregnancy.

METHODS

This study is a retrospective analysis of the pregnancy outcomes of 173 infertile patients who underwent hysteroscopy and laparoscopic tubal anastomosis treatment between January 2013 and August 2018 in the Department of Reproductive Endocrinology in West China Second University Hospital of Sichuan University. All patients had a history of laparoscopic salpingostomy for tubal pregnancy. The primary outcomes were intrauterine pregnancy, ectopic pregnancy, and delivery rates. We further studied the associated factors that could influence the change in pregnancy status.

RESULTS

The 24-month cumulative clinical pregnancy rate of all patients was 107/173 (61.8%). The distribution of outcomes for the entire group of pregnancies was as follows: intrauterine pregnancy rate, 76/173 (43.9%); ectopic pregnancy rate, 31/173 (17.9%); delivery rate, 68/173 (39.3%); and miscarriage rate, 8/173 (4.6%). Age, type of anastomosis, hydrosalpinx, and endometrial polyps were significant prognostic factors in the multivariate model.

CONCLUSION

Laparoscopic tubal anastomosis is an effective treatment for tubal-associated infertility due to previous laparoscopic salpingostomy for ectopic pregnancy, especially for women under 35 years of age.

Tubal Flushing Treatment for Unexplained Infertility

Tubal patency testing was initially introduced as a diagnostic test. However, it has been observed that some tubal patency tests also have a therapeutic effect. This therapeutic effect can be influenced by the contrast medium used during tubal flushing. In this review, we discuss current evidence associated with different methods for tubal flushing and their potential impact on reproductive outcomes in women with unexplained infertility. Furthermore, we discuss their diagnostic accuracy, safety, and cost-effectiveness.

Spontaneous conception outcome in infertile women after four-dimensional hysterosalpingo-contrast-sonography

BACKGROUND

Four-dimensional hysterosalpingo-contrast sonography (4D-HyCoSy) is the preferred way for evaluating fallopian tubal patency and it associated with higher rate of spontaneous conception. However, Few studies have evaluated the influencing factors of spontaneous conception in 4D-HyCoSy and suggested ways to choose treatment options after 4D-HyCoSy. The study was to evaluate the correlation between spontaneous conception outcome and the patients' clinical characteristics as well as tubal patency in infertile women to provide reference on ways to manage the patient after 4D-HyCoSy.

METHODS

This was a retrospective study and analysis of two hundred and eighty three (283) infertile patients who underwent a 4D-HyCoSy between December 2014 and October 2017 in our center. Eligible patients were those whose partners semen parameters were normal when based on World Health Organization (WHO) criteria, and had spontaneous conception without clinical interventions after 4D-HyCoSy.

RESULT(S)

One hundred and sixteen patients (40.9%) conceived spontaneously and the mean conception time was (8.8 ± 0.3) months. Within a year after 4D-HyCoSy, the spontaneous conception rate was highest in type VI(62.5%), followed by type IV (46.2%), type III (44.4%), type V (39.4%), type II (33.9%) and type I (14.8%). With Cox regression analysis, two factors associated with spontaneous conception outcome appeared to increase spontaneous conception rate: patients with type IV or type VI tubes and duration of infertility less than 2 years. The age, type of infertility, multiparas, history of pelvic surgery, history of uterine cavity operation, uterine fibromyomata and polycystic ovary were unrelated to spontaneous conception outcome after 4D-HyCoSy.

CONCLUSION(S)

This study showed that some infertile women could succeed in spontaneous conception after 4D-HyCoSy. Hence, We recommend the usage of 4D-HyCoSy as first line for tubal patency test and infertile patients should be advised to accept 4D-HyCoSy examination as soon as possible. Expectant treatment of about 8-9 months is reported to be feasible for infertile women whose 4D-HyCoSy findings showed one tube patency or poor patency. Alternatively, an immediate clinical intervention is recommended for those with bilateral obstructed tubes .

The pregnancy rate of infertile patients with proximal tubal obstruction 12 months following selective salpingography and tubal catheterization

OBJECTIVE

To assess the efficacy of selective salpingography (SSG) with additional tubal catheterization (TC) among infertile patients diagnosed with PTO and analysis of reproductive outcome.

STUDY DESIGN

Retrospective cohort study.

RESULTS

Of a total of 399 tubes with confirmed proximal tubal occlusion, 383 successfully restored their patency resulting in 96 % technical success rate. Thirty-five percent of oviducts that had their patency restored was treated with SSG and 65% required additional TC. Reproductive outcomes at minimum 12 months following the treatment were collected by a telephone survey. 21/221 women were lost to follow up. Out of remaining 200 patients with at least one patent tube, 80 patients conceived which resulted in 40 % overall pregnancy rate.

CONCLUSION

Selective salpingography and tubal canalization offer patient-friendly, minimally invasive and cost-effective alternatives to tubal microsurgery and IVF-ET in women with tubal occlusion with very high technical success rate and promising clinical results which depend also on the complexity of couple infertility. Specific indications and limitations make a careful assessment of fallopian tubes and comprehensive evaluation of partners' reproductive situation prior to therapy an absolute requirement.

Laparoscopic tuboplasty for mild distal tubal disease

OBJECTIVE

To review tuboplasty techniques for alleviating fallopian tube blockage.

DESIGN

A step-by-step explanation of the techniques that comprise tuboplasty-fimbrioplasty, salpingo-ovariolysis, and salpingostomy-with surgical video footage.

SETTING

Academic medical center.

PATIENT

A 28-year-old G0 female patient with primary infertility and bilateral fallopian tube occlusion wanting to avoid in vitro fertilization.

INTERVENTION(S)

Tuboplasty and its component techniques of fimbrioplasty, salpingo-ovariolysis, and salpingostomy are demonstrated in a stepwise fashion for a case of mild tubal disease. Fimbrioplasty includes identifying the agglutinated or phimosed fimbrial end and gently opening it with fine forceps and blunt microdissection. Salpingo-ovariolysis is demonstrated with video and comprises: 1) surveying the anatomy; 2) applying traction to delineate the adhesions; and 3) transecting the adhesions with microsurgical scissors or electrosurgery. Finally, the steps of a salpingostomy are demonstrated, including: 1) identifying the length of the fallopian tube; 2) performing chromotubation to delineate tubal obstruction; 3) creating a salpingostomy at the terminal end; and 4) suturing open the salpingostomy site circumferentially to evert the edges.

MAIN OUTCOME MEASURE(S)

Successful restoration of normal tubal anatomy and identification of the location of tubal occlusion to guide salpingostomy site placement.

RESULT(S)

The fallopian tubes were assessed bilaterally and noted to have mild tubal disease and therefore were appropriate for tuboplasty. Normal tubal anatomy was restored bilaterally through salpingo-ovariolysis. Subsequent identification of the area of tubal occlusion bilaterally and salpingostomy were performed to create a patent fallopian tube able to pick up an oocyte from the ovary and facilitate fertilization.

CONCLUSION(S)

Tubal reconstructive surgery remains an important option to offer patients who want to avoid in vitro fertilization and who have mild tubal disease.

Role of Reconstructive Microsurgery in Tubal Infertility in Young Women

AIM

Here, we retrospectively analyzed the success rate of reconstructive microsurgery for tubal infertility (RMTI) as a "first-line" approach to achieving tubal reversal and pregnancy after tubal infertility.

PATIENTS AND METHODS

During 9 consecutive years (2005-2014), 96 patients diagnosed with obstructive tubal infertility underwent RMTI (tubal reversal, salpingostomy, and/or tubal implantation) in our centre. The outcomes are presented in terms of tubal reversal rate and pregnancy and correlated with age, level of tubal obstruction, and duration of tubal infertility.

RESULTS

The overall tubal reversal rate was 87.56% (84 patients). The 48-month cumulative pregnancy rate was 78.04% (64 patients), of which seven ectopic pregnancies occurred (8.53%). The reversibility rate for women under 35 yo was 90.47%, with a birth rate of 73.01%. The reconstruction at the infundibular segments favored higher ectopic pregnancy rates (four ectopic pregnancies for anastomosis at infundibular level-57.14%, two for ampullary level-28.57%, and one for replantation technique-14.28%), with a significant value for p < 0.05.

CONCLUSIONS

In the context of IVF "industrialization", reconstructive microsurgery for tubal infertility has become increasingly less favored. However, under available expertise and proper indication, RMTI can be successfully used to restore a woman's ability to conceive naturally with a high postoperative pregnancy rate overall, especially in women under 35 yo.

Laparoscopic Tubal Re-anastomosis or In Vitro Fertilisation in Previously Ligated Patients: A Comparison of Fertility Outcomes and Survey of Patient Attitudes

Introduction: We aim to compare live birth rates, cost analysis and a survey of patient attitudes between laparosopic tubal re-anastomosis and IVF. Materials and Methods: Retrospective study: A retrospective study was done in a single reproductive medicine and IVF unit in Singapore, from January 2011 to December 2016. Previously ligated patients underwent either laparoscopic tubal re-anastomosis or IVF. The primary outcome was first live birth after treatment. Interval to first pregnancy, miscarriage and ectopic pregnancies were also reported. Survey: Patients attending the subfertility clinic completed a questionnaire on IVF and tubal re-anastomosis, on preferred choice of treatment, before and after reading an information sheet. Results: Retrospective study: 12 patients underwent tubal re-anastomosis while 31 patients underwent IVF treatment. Pregnancy (75.0% vs 35.5%) and live birth (58.3% vs 25.8%) were significantly higher in the tubal surgery group (P<0.05%) after transferring all available embryos in one stimulated IVF cycle. Cost per live birth was lower in the tubal surgery group (SGD27,109 vs SGD52,438). Survey: One hundred patients participated in the survey. A majority of patients preferred tubal surgery to IVF (68.2% vs 31.8%) before given information on the procedures, but indicated a preference for IVF (54.6%) to surgery (45.4%) after receiving information on the procedures. Conclusion: For women less than 40 years of age, desiring fertility after tubal ligation, laparoscopic tubal re-anastomosis offers better live birth rates and cost-effectiveness. Patients in Singapore are equivocal as to their preference after education regarding the choices. Thus laparoscopic tubal re-anastomosis remains a viable alternative to IVF treatment. Key words: Artificial reproductive technology, Laparoscopic tubal reversal, Previous tubal ligation

Proven and unproven methods for diagnosis and treatment of infertility

Infertility and subfertility affect a significant part of the population. Among various definitions of this pathology, the most common one is provided by the World Health Organisation; it says that infertility is 'a disease of the reproductive system defined by the failure to achieve a clinical pregnancy after 12 months or more of regular unprotected sexual intercourses'. The global prevalence of infertility is about 50-70 million couples. Since the process of human reproduction involves a large number of factors, a broad spectrum of infertility tests might be applied. Some of the tests focus directly on the pregnancy, some are only partially effective, whereas others should not be recommended for infertile couples. The aim of this review is to present a critical evaluation of the infertility diagnostic process and to discuss the recommendations for its most effective treatment.

Successful pregnancy in a woman with bilateral fallopian tube obstruction and diminished ovarian reserve treated with electroacupuncture: A case report

RATIONALE

Fallopian tube obstruction and diminished ovarian reserve (DOR) are main factors including female infertility. Acupuncture might be effective in the treatment of the disease.

PATIENT CONCERNS

A 39-year-old woman diagnosed with fallopian tube obstruction and DOR has been unable to conceive in the past 5 years, despite of receiving various treatments and 3-time in vitro fertilization (IVF) in different countries.

DIAGNOSES

Under comprehensive consideration of clinical manifestations and hysterosalpingography examinations results, the patient was diagnosed as female infertility due to fallopian tube obstruction and DOR.

INTERVENTION

Electroacupuncture treatment was performed 3 times per week for about 3 months.

OUTCOMES

After 2-months of electroacupuncture treatment, the patient's menstrual cycle was back to normal, and she conceived after 3-month treatment and gave birth to a healthy baby boy finally.

LESSONS

Electroacupuncture might be a complementary or alternative treatment for female infertility, particularly for women with fallopian tube obstruction and DOR.

Combination of noninvasive methods in diagnosis of infertile women with minimal or mild endometriosis, a retrospective study in China

This study means to investigate a combination of noninvasive methods in diagnosis of minimal or mild endometriosis expecting to narrow down the range of laparoscopic exploration for female infertility.It is a retrospective case control study of totally 447 patients suspected unexplained infertility before surgery were eligible from May 2012 to February 2017. Of these, 299 patients were laparoscopy-proved minimal or mild endometriosis group, the remaining 148 patients served as control group (normal pelvis). Preoperative age, duration of infertility, type of infertility, body mass index, baseline follicle-stimulating hormone, anti-Müllerian hormone, serum CA125, clinical symptoms, findings on vagino-recto-abdominal examinations and pregnancy prognosis had been recorded. Every variable and their combinations were evaluated.Any single factor had limited diagnostic value. The cut-off value for CA125 was 19.25 IU/L. Parallel testing had a higher sensitivity at 81.3%. Serial tests of vagino-recto-abdominal examination combined with dysmenorrhea or positive CA125 got reasonable sensitivity (51.4% and 49%), remarkable high specificities (95.7% and100%) and Positive Predictive Value (96.4% and 100%). Multivariate logistic regression identified the following factors in decreasing order of importance: (1) vagino-recto-abdominal examinations, (2) CA125, (3) dysmenorrhea, their ORs being 16.148, 3.796, and 2.809, respectively. The spontaneous pregnancy rate (50.8%) in minimal or mild endometriosis was higher than control (35.6%, P = .043).A combination of noninvasive diagnostic methods had certain preoperative diagnostic value of minimal or mild endometriosis, which might benefit some patients from avoiding laparoscopic surgery.

The human tubal lavage proteome reveals biological processes that may govern the pathology of hydrosalpinx

Hydrosalpinx, the blockage of fallopian tubes, can result from pelvic inflammatory disease. Hydrosalpinx is a cause of infertility and negatively impacts in vitro fertilization. To better understand the pathobiology of hydrosalpinx, we compared the proteome of lavages from disease vs. healthy fallopian tubes. Results indicate a disruption of redox homeostasis and activation of the complement system, immune cell infiltration, and phagocytosis; pathways that may drive tubal injury. To our surprise among the most prominent proteins with hydrosalpinx was mesothelin (MSLN), which until now has only been associated with epithelial malignancies. Analogous to mesothelioma and ovarian carcinoma, a significant increase of MSLN was detected in plasma from patients with hydrosalpinx. This finding suggests MSLN may provide clinical diagnosis in lieu of the current approaches that require invasive imaging. Importantly, these findings implicate MSLN in a benign disease, indicating that the activation and role of MSLN is not restricted to cancer.

Chronic fetal hypoxia disrupts the peri-conceptual environment in next-generation adult female rats

KEY POINTS

Exposure to chronic hypoxia during gestation influences long-term health and development, including reproductive capacity, across generations. If the peri-conceptual environment in the developing oviduct is affected by gestational hypoxia, then this could have implications for later fertility and the health of future generations. In the present study, we show that the oviducts of female rats exposed to chronic hypoxia in utero have reduced telomere length, decreased mitochondrial DNA biogenesis and increased oxidative stress The results of the present study show that exposure to chronic gestational hypoxia leads to accelerated ageing of the oviduct in early adulthood and they help us understand how exposure to hypoxia during development could influence reproductive health across generations.

ABSTRACT

Exposure to chronic hypoxia during fetal development has important effects on immediate and long-term outcomes in offspring. Adverse impacts in adult offspring include impairment of cardiovascular function, metabolic derangement and accelerated ovarian ageing. However, it is not known whether other aspects of the female reproductive system may be similarly affected. In the present study, we examined the impact of chronic gestational hypoxia on the developing oviduct. Wistar rat dams were randomized to either normoxia (21%) or hypoxia (13%) from day 6 post-mating until delivery. Post-delivery female offspring were maintained in normoxia until 4 months of age. Oviductal gene expression was assayed at the RNA (quantitative RT-PCR) and protein (western blotting) levels. Oviductal telomere length was assayed using Southern blotting. Oviductal telomere length was reduced in the gestational hypoxia-exposed animals compared to normoxic controls (P < 0.01). This was associated with a specific post-transcriptional reduction in the KU70 subunit of DNA-pk in the gestational hypoxia-exposed group (P < 0.05). Gestational hypoxia-exposed oviducts also showed evidence of decreased mitochondrial DNA biogenesis, reduced mtDNA copy number (P < 0.05) and reduced gene expression of Tfam (P < 0.05) and Pgc1α (P < 0.05). In the hypoxia-exposed oviducts, there was upregulation of mitochondrial-specific anti-oxidant defence enzymes (MnSOD; P < 0.01). Exposure to chronic gestational hypoxia leads to accelerated ageing of the oviduct in adulthood. The oviduct plays a central role in early development as the site of gamete transport, syngamy, and early development; hence, accelerated ageing of the oviductal environment could have important implications for fertility and the health of future generations.

A Novel Technique for Essure Reversal

Background and Objectives:

An increasing number of women are seeking removal of the Essure sterilization device due to symptoms including pelvic pain, abnormal bleeding, and allergic reaction. A fraction of these women also desire a future pregnancy and request sterilization reversal at the time of device removal. We present a novel technique for Essure reversal in addition to our experience with three cases.

Methods:

Simultaneous laparoscopy and hysteroscopy is used to remove the device followed by laparoscopic reimplantation of the distal fallopian tube to the uterine fundus. A video of our method is included and the outcomes of three patients reported.

Results:

Three women underwent laparoscopic Essure reversal for device-attributed symptoms and desire to restore fertility between 2017 and 2018. All procedures were uncomplicated with restoration of tubal patency in one or both fallopian tubes on follow-up hysterosalpingogram. Over a period of 4 to 10 months of followup, no pregnancies have been reported.

Conclusion:

Essure reversal is a feasible technique for removing the device and restoring tubal patency; however, more data are needed on pregnancy outcomes following this novel procedure.

Laparoscopic Reversal of Tubal Sterilization; A Retrospective Study Over 135 Cases

Objectives: To evaluate the pregnancy and delivery rates of laparoscopic tubal reanastomosis.

Study Design: From 2003 to 2013, 135 laparoscopic tubal reversals were performed according to the four stitch technique. The parameters studied, included positive pregnancy test, miscarriage, ectopic pregnancy, termination of pregnancy, term delivery, post-operative time to conception, post-operative hysterosalpingography, and spermogram.

Results: From the 135 patients operated, 93 fulfilled the inclusion criteria. The age of patients varied from 27 to 47 years old. All ages combined, positive β-HCG blood sample rate was 75.3% (95% CI: 65.0–83.4%) and term delivery 52.7% (95%CI: 42.1–3.0%). The age-adjusted pregnancy and delivery rates were as follows:

27–35 y.o. (n = 23) 95.7% (95%CI: 76.0–99.8%) and 73.9% (95%CI: 51.3–88.9%),

36–39 y.o. (n = 40) 77.5% (95%CI: 61.1–88.6%) and 47.5% (95%CI: 31.8–63.7%),

40–42 y.o. (n = 19) 68.4% (95%CI: 43.5–86.4%) and 52.6% (95%CI: 29.5–74.8%),

43–47 y.o. (n = 11) 36.4% (95%CI: 12.4–68.4%) and 27.3% (95%CI: 7.3–60.7%).

Conclusions: In our series the pregnancy and delivery rates after laparoscopic reversal of tubal sterilization is estimated at 75.3 and 52.7%, respectively. For women with tubal sterilization and no other infertility factors, reanastomosis can restore anterior natural fertility related to age. Laparoscopic reversal should be proposed systematically to patients and performed by well-trained laparoscopists, avoiding potentially the inconvenient and adverse outcomes of an IVF treatment. Although, it may seem a more cost-effective technique compared to robotically assisted reversal, a prospective randomized trial could answer this question.

Hysteroscopic Placement of Platinum Microinsert in Patients With Hydrosalpinx Before In Vitro Fertilization and Embryo Transfer

OBJECTIVE

To investigate the effectiveness of Tornado and Hilal (Cook Medical, Bloomington, IN) hysteroscopic proximal tubal occlusion (HPTO) for hydrosalpinx (HX) treatment before in vitro fertilization (IVF) and embryo transfer (ET) in patients with dense pelvic adhesions or low ovarian reserve.

DESIGN

A retrospective study of patients treated between May 2014 and May 2016 (Canadian Task Force classification III).

SETTING

A university-affiliated center.

PATIENTS

One hundred fifty women with unilateral or bilateral HX who were not candidates for laparoscopic surgery.

INTERVENTION

Tornado or Hilal HPTO before IVF-ET and/or frozen ET.

MEASUREMENTS AND MAIN RESULTS

The main outcome was the cumulative live birth rate. Tornado or Hilal placement was successful for 143 (95.3%) patients. Of the 132 patients who underwent 204 ET cycles, 86 (65.2%) conceived, and 78 (59.1%) resulted in live births. The overall early and late miscarriage rates per clinical pregnancy were 12.8% and 1.1%, respectively. The ectopic pregnancy rate was 2.3%. No major complications occurred.

CONCLUSION

Tornado or Hilal HPTO is an effective alternative for treating HX before IVF-ET/frozen ET in patients with dense pelvic adhesions or low ovarian reserve.

Effect of Premedication Hyoscine-N-Butylbromide before Hysterosalpingography for Diagnosis of Proximal Tubal Obstruction in Infertile Women: A Randomized Double-Blind Controlled Trial

STUDY OBJECTIVE

To assess the effect of hyoscine-N-butylbromide (HBB) as premedication on the rate of proximal tubal obstruction during hysterosalpingography (HSG).

DESIGN

A randomized, double-blind controlled trial (Canadian Task Force classification I).

SETTING

The Infertility Clinic of Songklanagarind Hospital.

PATIENTS

One hundred and forty-six infertile women indicated for HSG investigation.

INTERVENTIONS

Between May 1, 2016, and March 31, 2017, patients were assigned at random to receive either oral HBB 20 mg or placebo 30 minutes before the HSG procedure. If proximal tubal obstruction was found, participants were be assigned to undergo a second confirming HSG or laparoscopy with chromopertubation within 6 months.

MEASUREMENTS AND MAIN RESULTS

The primary outcome was the rate of proximal tubal obstruction. The secondary outcome was the false-positive result of proximal tubal occlusion from HSG. Proximal tubal obstruction was found in 6 of 70 patients in the HBB group and in 16 of 71 in the placebo group. The rate of proximal tubal obstruction was significantly lower in the HBB group than in the placebo group (8.6% vs 22.5%; p = .04; absolute difference, 13.9%; 95% confidence interval [CI], 0.02-0.26; relative risk, 0.38; 95% CI, 0.16-0.92). After the second HSG or laparoscopy was performed (n = 22), the rate of false occlusion was 20% (1 of 6 patients) in the HBB group, compared with 69.2% (9 of 16 patients) in the placebo group.

CONCLUSION

Premedication with HBB before HSG can reduce the rate of diagnosis of proximal tubal obstruction and false occlusion.

Isolated fallopian tube torsion with hydrosalpinx: Review of a debated management in a pediatric population

PURPOSE

To quantify our experience with and assess the literature on diagnosis and management of isolated fallopian tube torsion (IFTT) with hydrosalpinx (HSX) in children.

METHODS

A PubMed search was performed on pediatric cases of IFTT with HSX to provide a comprehensive review analyzing details and management of this association, focusing on the problem of fertility preservation.

RESULTS

In addition to our 3 cases, 17 patients of pediatric IFTT associated with HSX were identified, for a total of 21 cases (median age 12.2 years). Menarchal status was present in 10/13 (76.9%); blood tests were reported in 9/20 (42%) showing leucocytosis in 7/9 (75%). Ultrasonography was performed in all cases except one. Laparoscopy was the surgical approach in 84.6% of the reported cases. The torsion was to the right in 36.8%, and to the left in 63.2% of the cases. In one case the torsion was bilateral and asynchronous. Performed procedures were salpingectomy (52.4%) and partial salpingectomy (14.3%); conservative management was reported in 33.3% of the cases.

CONCLUSIONS

The literature describes different management techniques. Salpingectomy is the most frequently performed procedure but recently conservative management seems to be increasingly applied. A long-term study is necessary to define the most effective treatment for the preservation of future fertility in pediatric patients.

TYPE OF STUDY

Treatment study (Retrospective Study): LEVEL IV.

Surgery for tubal infertility

BACKGROUND

Surgery remains an acceptable treatment modality for tubal infertility despite the rise in usage of in vitro fertilisation (IVF). Estimated livebirth rates after surgery range from 9% for women with severe tubal disease to 69% for those with mild disease; however, the effectiveness of surgery has not been rigorously evaluated in comparison with other treatments such as IVF and expectant management (no treatment). Livebirth rates have not been adequately assessed in relation to the severity of tubal damage. It is important to determine the effectiveness of surgery against other treatment options in women with tubal infertility because of concerns about adverse outcomes, intraoperative complications and costs associated with tubal surgery, as well as alternative treatments, mainly IVF.

OBJECTIVES

The aim of this review was to determine the effectiveness and safety of surgery compared with expectant management or IVF in improving the probability of livebirth in the context of tubal infertility (regardless of grade of severity).

SEARCH METHODS

We searched the following databases in October 2016: the Cochrane Gynaecology and Fertility (CGF) Group trials register, the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Embase, the Cumulative Index to Nursing and Allied Health Literature (CINAHL) and PsycINFO; as well as clinical trials registries, sources of unpublished literature and reference lists of included trials and related systematic reviews.

SELECTION CRITERIA

We considered only randomised controlled trials to be eligible for inclusion, with livebirth rate per participant as the primary outcome of interest.

DATA COLLECTION AND ANALYSIS

We planned that two review authors would independently assess trial eligibility and risk of bias and would extract study data. The primary review outcome was cumulative livebirth rate. Pregnancy rate and adverse outcomes, including miscarriage rate, rate of ectopic pregnancy and rate of procedure-related complications, were secondary outcomes. We planned to combine data to calculate pooled odds ratios (ORs) and 95% confidence intervals (CIs). We planned to assess statistical heterogeneity using the I2 statistic and to assess the overall quality of evidence for the main comparisons using GRADE methods.

MAIN RESULTS

We identified no suitable randomised controlled trials.

AUTHORS' CONCLUSIONS

The effectiveness of tubal surgery relative to expectant management and IVF in terms of livebirth rates for women with tubal infertility remains unknown. Large trials with adequate power are warranted to establish the effectiveness of surgery in these women. Future trials should not only report livebirth rates per patient but should compare adverse effects and costs of treatment over a longer time. Factors that have a major effect on these outcomes, such as fertility treatment, female partner's age, duration of infertility and previous pregnancy history, should be considered. Researchers should report livebirth rates in relation to severity of tubal damage and different techniques used for tubal repair, including microsurgery and laparoscopic methods.

Recent developments have made female permanent contraception an increasingly attractive option, and pregnant women in particular ought to be counselled about it

BACKGROUND

Despite the increased prevalence of reversible contraception, global unintended pregnancy rates are stable. Mistakes, method failures, side effects, alcohol, stock-outs, fears, costs, delays, myths, religious interference, doctors with other priorities, traditions and lack of health professionals may all factor in. Yet these unintended pregnancies - nearly a hundred million annually - cause much individual suffering, and in the long run, can aggravate conflicts, poverty, forced emigration and climate change. Presently, non-poor women postpone childbearing because of longer educational trajectories and careers. Sterilisations are therefore less often regretted or coerced. For poor-resourced women with a completed family, an unwanted pregnancy often has serious consequences, including crossing the (extreme) poverty line in the wrong direction, choosing an unsafe abortion, or even death. Caesarean sections (CSs), which currently stand at around 23 million annually, are increasing. On an "intention-never-to-become-pregnant-again" analysis, choosing a partial, and even more so a total bilateral tubectomy to be implemented during an - anyway performed - CS is by far the most reliable and safe contraceptive choice compared to meaning to start female or male sterilisation or any other contraceptive method later, and it reduces the chance of a future ovarian carcinoma substantially. CSs make subsequent pregnancies more dangerous. Simultaneously, they provide convenient, potentially cost-free opportunities for voluntary permanent contraception (PC): particularly important if there is no guaranteed future access to reliable contraception, safe abortion and well-supervised labour.

PARTIAL SOLUTION

Millions of women are within reach of attaining freedom from the "tyranny of excessive fertility" when they have a CS. Therefore, any woman who might conceivably be of the firm opinion that her family will be (over) completed after delivery should antenatally have "what if you have a CS" counselling to assess whether she would like a tubectomy/ligation. Yet many are not provided with this option: leading to frequent regret, more often than having been giving that choice would.

CONCLUSION

Withholding antenatal counselling about the option of PC for in case the delivery might become a CS is very prevalent, yet often more medically risky, and morally questionable than when, even in labour, a doctor sometimes decides in the absence of earlier counselling, considering numerous factors, to provide the choice to undergo a concurrent sterilisation if s/he is convinced that would be in the patient's best interest.

3 to 5 Years Later: Long-term Effects of Prophylactic Bilateral Salpingectomy on Ovarian Function

STUDY OBJECTIVE

Preliminary data on the effects of prophylactic bilateral salpingectomy (PBS) show that postoperative ovarian function is preserved up to 3 months after surgery. The confirmation of PBS safety on ovarian function even many years after surgery is essential to reassure the medical community that this new strategy, recently proposed for the prevention of ovarian cancer, is at least able to avoid the risk of premature surgical menopause. We investigated whether the addition of PBS during total laparoscopic hysterectomy (TLH) causes long-term effects on ovarian function.

DESIGN

An observational study (Canadian Task Force classification II-3).

SETTING

Department of Obstetrics and Gynecology, "Magna Graecia" University, Catanzaro, Italy.

PATIENTS

Seventy-nine patients who underwent TLH plus salpingectomy between September 2010 and September 2012 at our institution have been recalled to be submitted to ovarian reserve evaluation in February 2015. Eight of 79 women refused to participate in this follow-up study.

INTERVENTIONS

The ovarian age of PBS patients has been determined through OvAge (OvAge sr., Catanzaro, Italy), a statistical model that combines antimüllerian hormone, follicle-stimulating hormone, 3-dimensional antral follicle count, vascular index, flow index, and vascular flow index values. The control group consisted of a large population of 652 healthy women (with intact uterus and adnexa) previously enrolled to build the OvAge model. Comparisons between ovarian ages of PBS patients and the control group have been assessed by analysis of covariance linear statistical modeling.

MEASUREMENTS AND MAIN RESULTS

The main outcome measurement was the differences in the behavior within OvAge/age relation between PBS and control women. Descriptive statistics of those 71 enrolled PBS patients are the following: age, 49.61 ± 2.15 years; OvAge, 49.22 ± 2.57 years; follicle-stimulating hormone, 43.02 ± 19.92 mU/mL; antimüllerian hormone, 0.12 ± 0.20 ng/mL; 3-dimensional antral follicle count, 1.91 ± 1.28; vascular index, 2.80% ± 5.32%; flow index, 19.37 ± 5.88; and vascular flow index, 0.56 ± 1.12. Analysis of covariance disclosed that PBS and control women do not exhibit different behaviors (p = .900) within OvAge/age relation.

CONCLUSION

According to our model, the addition of PBS to TLH in the late reproductive years does not modify the ovarian age of treated women up to 3 to 5 years after surgery.

Spontaneous bilateral torsion of fallopian tubes presenting as primary infertility

Case presented at "Stump the Professors" 44th American Association of Gynecologic Laparoscopists Global Congress on Minimally Invasive Gynecology, NV, USA, 15-19 November 2015 BACKGROUND: Spontaneous torsion of the fallopian tubes is a rare condition, usually seen in acute settings or as incidental findings during laparoscopy.

PRESENTATION OF THE CASE

A 34-year-old nulligravid woman with inability to conceive for 7 months presented to our center. Her hysterosalpingography revealed a blind-ending right fallopian tube, and a blocked and dilated left fallopian tube. Laparoscopy showed a long, auto-amputated right fallopian tube, disconnected from the fimbriae and a long, dilated left fallopian tube, with several twists around its axis. Bilateral salpingectomy was performed. The patient subsequently underwent IVF, resulting in an ongoing pregnancy.

CONCLUSION

Spontaneous torsion of the fallopian tubes can manifest as primary infertility without any antecedent symptoms, and should be considered in the differential diagnosis of bilateral tubal obstruction.
