Diagnostic laparoscopy is needed after abnormal hysterosalpingography to prevent over-treatment with IVF

Diagnostic laparoscopy prior to IVF cycle improves outcome in patients with unilateral distal tubal occlusion

OBJECTIVE

To assess the impact of laparoscopy before in vitro fertilization (IVF) treatment on live birth rates in patients with distal unilateral tubal obstruction (UTO).

METHODS

Retrospective cohort study which was conducted in tertiary ART center in Ankara University Hospital between January 2008- January 2019. Inclusion criteria were distal UTO at HSG, patients who were 18-40 years age and baseline serum FSH levels between 3-15 IU/ml. Exclusion criteria were patients who had previous tubal surgery and, hormonal dysfunction such as hyperprolactinemia or hypothyroidism at the time of the IVF cycle.

RESULTS

49 patients who underwent 117 IVF treatment cycles were included in the final analysis. Among those 17 patients (34 IVF cycles) in the study group who underwent laparoscopy prior to IVF cycles, and 32 patients (83 IVF cycles) in the control group who directly underwent IVF cycle with no prior laparoscopy. Eleven pathologies (64.7%) were detected and treated at laparoscopies of 17 patients with distal UTO. Both the clinical pregnancy and the live birth rates were also significantly higher in the study group when compared to the control group (29.4% vs. 12%, P=.031; 26.5% vs. 9.6%, respectively; P=.039).

CONCLUSIONS

Patients with distal UTO generally have a pelvic pathology and laparoscopy prior to IVF cycles can improve the treatment outcome.

Systematic use of transvaginal hydrolaparoscopy as a minimally invasive procedure in the exploration of the infertile patient: results and reflections

Background

The aim of this study was to evaluate the added value of transvaginal hydrolaparoscopy (THL) in the investigation of the infertile patient.

Methods

A retrospective cohort study, based on records from 01/09/2006 to 30/12/2019 was undertaken in a tertiary care infertility centre. THL was performed in 2288 patients. These were patients who were referred for endoscopic exploration of the female pelvis as part of their infertility investigation. In 374 patients with clomiphene- resistant polycystic ovary syndrome (PCOS), ovarian capsule drilling was also performed. The outcome objectives of this study included the evaluation of the added diagnostic value of THL as well as the feasibility and safety of the visual inspection of the female pelvis using this technique.

Results

Of the 2288 procedures failed access to the pouch of Douglas occurred in in 23 patients (1%). The complication rate was 0.74%, due to bowel perforations (n= 13) and bleeding (n= 4) requiring laparoscopy. All bowel perforations were treated conservatively, with 6 days of antibiotics, and no further complications occurred. Findings were normal in 49.8% of patients. Endometriosis was diagnosed in 366 patients (15.9%); adhesions were present in 144 patients.

Conclusions

THL is a minimally invasive procedure, with a low complication and failure rate, providing an accurate visual exploration of the female pelvis in a one-day hospital setting. When indicated, minimally invasive surgery is possible in the early stages of endometriosis and for ovarian capsule drilling in patients with clomiphene- resistant PCOS.

Unexplained infertility categorization based on female laparoscopy and total motile sperm count, and its impact on cumulative live-births after one in-vitro fertilization cycle. A retrospective cohort study involving 721 cycles

PURPOSE

To determine how subcategorizing unexplained infertility based on female laparoscopy and total-motile-sperm-count assessment would impact cumulative live-births after one in-vitro fertilization (IVF) cycle.

METHODS

Seven hundred twenty one IVF cycles from Jan 2014-April 2019 performed at a single-center were retrospectively analyzed. Couples with unexplained infertility having normal uterine and endometrial morphology were subcategorized into three cohorts, UI (1): those with no tuboperitoneal pathology on laparoscopy and total-motile-sperm-count (TMSC) ≧20 million: n = 103; UI (2): tuboperitoneal pathology on laparoscopy or TMSC <20 million, n = 86; and UI(3): tuboperitoneal status not known: n = 114. Controls were severe male factor, bilateral tubal block, and grade 3/4 endometriosis: n = 418. Primary Outcome was cumulative-live-birth-per-initiated-IVF cycle (CLBR). Odds ratio for live-births were adjusted for confounding factors.

RESULTS

The CLBR in UI1 cohort was significantly lower than controls (29.1% vs 39; OR = 0.62; 95%CI = 0.39-0.98; P = .04); but similar in UI2 and UI3 vs. controls. (37.2% vs 39.95%; OR = 0.89, 95%CI = 0.55-1.44; P = .89) and (38.6% vs 39.95%; OR = 0.98, 95%CI = 0.64-1.55; P = .98). After adjusting for age, infertility duration, past live-births, and AMH, the adjusted odds for CLBR in UI1 was 0.48 (95%CI = 0.28-0.82; P = .007).

CONCLUSIONS

Unexplained infertility when defined after a normal laparoscopy and TMSC significantly lowered cumulative-live-births-per-initiated-IVF cycle when compared with traditional diagnosis of tubal, endometriosis, or male factor infertility. In UI subcategory with abnormal laparoscopy or TMSC, CLBR remained unaffected. This information could be useful for counseling couples prior to IVF. Large-scale prospective studies are needed to confirm this observation.

The validity of HSG in infertility work up

Background

Our purpose was to evaluate the diagnostic accuracy of hysterosalpingography (HSG) in the diagnosis of the uterine cavity and tuboperitoneal abnormalities in infertile women. Reproducibility and consistency were also assessed. Two hundred infertile females underwent HSG, hysteroscopy, and/or laparoscopy as part of infertility workup. HSG examinations were retrospectively reviewed by three radiologists; we compared interobserver variability, and differences between the two results of reading the same examination after 3 months were compared to calculate intraobserver variability.

HSG sensitivity, specificity, PPV, NPV, and accuracy were calculated.

Results

The overall accuracy of HSG in diagnosing tubal, uterine cavity, and peritoneal abnormalities was 95.5%, 95%, and 89%, respectively (P value < 0.04).

HSG is reproducible in diagnosing normal versus abnormal examinations. Reproducibility in diagnosing uterine cavity, tubal, and peritoneal abnormalities was (ICC = 0.90), (ICC = 0.70), and (ICC = 0.31), respectively. Best agreement was seen in diagnosing luminal filling defect (sub mucous fibroid/polyp) (ICC = 0.90) (95% CI 0.86–0.98), whereas poorest agreement was found in diagnosing uterine adhesions (ICC = 0.13) (95% CI 0.10–0.13) and pelvic adhesions (ICC = 0.12) (95% CI 0.10–0.13) (P value < 0.03).

HSG consistency ranged from moderate to good (K = 0.49–0.79). It was highest in diagnosing normal versus abnormal examination (P value < 0.01); poorest in diagnosing pelvic adhesions.

Conclusion

HSG has high validity in negative results; it can minimize the use of invasive procedures. Laparoscopy is recommended in patients who had a pelvic disease or showing tubal obstruction on HSG.

Anatomical causes of female infertility and their management

The main female anatomical causes of infertility include post-infectious tubal damage, endometriosis, and congenital/acquired uterine anomalies. Congenital (septate uterus) and acquired (myomas and synechiae) diseases of the uterus may lead to infertility, pregnancy loss, and other obstetric complications. Pelvic inflammatory disease represents the most common cause of tubal damage. Surgery still remains an important option for tubal factor infertility, with results in terms of reproductive outcome that compare favorably with those of in vitro fertilization. Endometriosis is a common gynecologic condition affecting women of reproductive age, which can cause pain and infertility. The cause of infertility associated with endometriosis remains elusive, suggesting a multifactorial mechanism involving immunologic, genetic, and environmental factors. Despite the high prevalence of endometriosis, the exact mechanisms of its pathogenesis are unknown. Specific combinations of medical, surgical, and psychological treatments can ameliorate the quality of life of women with endometriosis. In the majority of cases, surgical treatment of endometriosis has promoted significant increases in fertilization rates. There are obvious associations between endometriosis and the immune system, and future strategies to treat endometriosis might be based on immunologic concepts.

The significance of laparoscopy in determining the optimal management plan for infertile patients with suspected tubal pathology revealed by hysterosalpingography

The fallopian tube has numerous functions, including ovum pick-up, the place of fertilization of the ovum and cleavage of the embryo, and transfer of the embryo to the uterus. Tubal pathology impairs functions of the fallopian tube and reduces fertility. The degree of tubal pathology determines the possibility for fertility. The evaluation of the fallopian tube is necessary to determine the management plan of infertility. Hysterosalpingography (HSG) is often performed as a first line approach to assess tubal patency and the presence of adhesions; however, HSG has limitations in detecting tubal pathology. In the current study, we evaluated the significance of laparoscopy in determining the optimal management plan for infertile patients with suspected tubal pathology revealed by HSG. Between 1997 and 2009, 127 patients with suspected tubal pathology as demonstrated by HSG underwent laparoscopy at Kinki University Hospital, and a retrospective analysis was performed. Of 87 patients with unilateral tubal pathology revealed by HSG, 20 patients (23.0%) were given an indication for assisted reproductive technology (ART), based on the laparoscopic findings. Of 40 patients with bilateral tubal pathology revealed by HSG, 33 patients (82.5%) with bilateral tubal pathology detected by laparoscopy were given a high indication for ART. Laparoscopy enables exact evaluation of the fallopian tube and selection of the optimal management plan in infertile patients with suspected tubal pathology revealed by HSG. Therefore, laparoscopy should be performed in infertile patients with suspected tubal pathology revealed by HSG, as it is of diagnostic importance.

Diagnostic accuracy and efficacy of color Doppler mapping for tubal patency

AIM

To evaluate the diagnostic accuracy of color Doppler mapping for tubal patency, comparing its results with those of hysterosalpingography (HSG) and laparoscopy.

MATERIAL AND METHODS

A prospective clinical study was conducted in 36 subfertile women who were offered laparoscopy after HSG evaluation. All infertile couples were evaluated with basic infertility procedures. After HSG assessment, laparoscopy was offered when evidence of either unilateral or bilateral tubal obstruction was observed. One day before the operation, transvaginal ultrasound scanning of the pelvis and color Doppler mapping were performed. The findings of sonography, HSG and laparoscopy were compared.

RESULTS

Sixty-four of 72 fallopian tubes were evaluated and four patients were excluded from the analysis because of technical difficulties. The sensitivity of color Doppler mapping for detecting tubal patency was 76.2% with a specificity of 81.4%. The positive and negative predictive values were 66.7% and 87.5%, respectively. The concordance rate was 79.7%. The false positivity rate for color Doppler mapping and HSG were observed as 19% and 35%, respectively.

CONCLUSION

Color Doppler mapping as an adjunct to an abnormal HSG may decrease the need for laparoscopic intervention for the diagnosis of tubal disorders.

A new evaluation score that uses salpingoscopy to reflect fallopian tube function in infertile women

OBJECTIVE

To build an evaluation scoring system using the results of salpingoscopy, and to evaluate the relationship between this scoring system and the outcome of pregnancy.

DESIGN

Retrospective study.

SETTING

Sugiyama Clinic.

INTERVENTION(S)

Using salpingoscopy, we observed the tubal lumen, paying attention to the following six results: adhesions, loss of mucosal folds, rounded edges of mucosal folds, debris, foreign bodies, and abnormal vessels.

PATIENT(S)

From April 2008 through June 2009, 104 women in whom unexplained infertility had been diagnosed underwent salpingoscopy. The F scores were evaluated related with various clinical results or pregnancy rates.

MAIN OUTCOME MEASURE(S)

The F score expressed the sum of the abnormal results, and one abnormal result was given a 1-point F score.

RESULTS

Approximately 60% of the patients showed an F score of 0, and the percentages of patients who showed 1, 2, 3, and ≥4 points were 19.2%, 11.5%, 4.5%, and 4.5%, respectively. After evaluation, 23 patients achieved pregnancy within a year. The pregnancy rates for patients with F scores of 0 and 1 point were 30.6% and 20.0%, respectively, and the rate of patients with an F score of 0 was significantly higher than the rate of patients with high F scores (F score ≥2; 9.1%).

CONCLUSION(S)

The patients showing a lower F score (0 or 1) showed higher fecundity than those showing an F score of ≥2.
