Usefulness of transvaginal hydrolaparoscopy in investigating infertile women with Chlamydia trachomatis infection

Fertility-related quality of life in subfertile women undergoing tubal testing with transvaginal hydrolaparoscopy or hysterosalpingography

OBJECTIVE

Both subfertility and its management can have significant impact on quality of life (QoL). Tubal patency testing as part of the fertility work-up, is considered to cause more physical complaints and stress than other tests. Pain scores for HSG are higher than for THL, but acceptability of the procedures was found to be comparable. Fertility-related QoL has not yet been studied in women undergoing tubal patency testing.

STUDY DESIGN

We performed a standardized questionnaire study alongside a previously reported randomized controlled trial comparing THL and HSG in subfertile women, in which 24-month live birth rates occurred in 58.5% versus 55.4%, respectively. We randomly assigned 300 subfertile women to THL or HSG between May 2013 and October 2016. Women were eligible if they were undergoing a fertility work-up with an indication for evaluation of tubal patency. Fertility-related QoL was measured six weeks after the procedure with the validated FertiQoL questionnaire. The scores for the Core scale and subscales between THL and HSG were compared using Mann-Whitney-U test and multiple linear regression analysis.

RESULTS

The questionnaire was completed by 84 women in the THL group (56%) and 96 women in the HSG group (64%). Core scores were 74.6 ± 12.8 for THL and 73.4 ± 12.4 for HSG (p = 0.39). Scores for the Emotional domain were 64.5 ± 19.0 for THL versus 66.0 ± 16.3 (p = 0.67) for HSG. Scores for the 'Mind-body' domain for THL were 76.9 ± 15.6 versus 74.1 ± 18.0 for HSG (p = 0.42), while scores for the Relational domain were 79.2 ± 12.9 for THL and 76.9 ± 15.6 for HSG (p = 0.21). Scores for the Social domain for THL were 77.9 ± 15.1 versus 76.7 ± 14.1, (p = 0.42). The multiple linear regression analysis showed only a statistical significant positive effect of older age on the score for the Emotional domain (p = 0.015).

CONCLUSION

In a preselected group of women with low risk for tubal pathology we did not find differences in fertility-related QoL between tubal patency testing with THL versus HSG.

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.

Transvaginal hydrolaparoscopy versus hysterosalpingography in the work-up for subfertility: a randomized controlled trial

RESEARCH QUESTION

Is transvaginal hydrolaparoscopy (THL) non-inferior to hysterosalpingography (HSG) as a first-line tubal patency test in subfertile women in predicting the chance of conception leading to live birth?

DESIGN

A multicentre, randomized controlled trial in four teaching hospitals in the Netherlands, which randomized subfertile women scheduled for tubal patency testing to either THL or HSG as a first-line tubal patency test. The primary outcome was conception leading to live birth within 24 months after randomization.

RESULTS

A total of 149 women were randomized to THL and 151 to HSG. From the intention-to-treat population, 83 women from the THL group (58.5%) conceived and delivered a live born child within 24 months after randomization compared with 82 women (55.4%) in the HSG group (difference 3.0%, 95% CI -8.3 to 14.4). Time to conception leading to live birth was not statistically different between groups. Miscarriage occurred in 16 (11.3%) women in the THL group, versus 20 (13.5%) women in the HSG group (RR = 0.66, 95% CI 0.34 to 1.32, P = 0.237), and multiple pregnancies occurred in 12 (8.4%) women in the THL group compared with 19 (12.8%) women in the HSG group (RR = 0.84, 95% CI 0.46 to 1.55, P = 0.58). Ectopic pregnancy was diagnosed in two women in the HSG group (1.4%) and none in the THL group (P = 0.499).

CONCLUSION

In a preselected group of subfertile women with a low risk of tubal pathology, use of THL was not inferior to HSG as a first-line test for predicting conception leading to live birth.

Operative transvaginal hydrolaparoscopy improve ovulation rate after clomiphene failure in polycystic ovary syndrome

Aim of our study was to assess the ovulation rate, with mid-luteal progesterone level and ultrasound follicles monitoring, in PCOS CC-resistant patients undergone transvaginal hydrolaparoscopy ovarian drilling. A prospective observational study was carried out in 123 PCOS, infertile, CC-resistant patients who undergone THL ovarian drilling. Each woman was evaluated by hormonal measurement, and ultrasound evaluation during 6 months follow-up. Progesterone serum levels were assessed on days 20-24 of the cycle after surgical treatment. Pg levels >3 ng/mL were considered as ovulation. Ovulation frequency and the highest mean follicular diameters during the monitoring were recorded. 117 patients complete the study, since six patients were lost to follow-up. Mean follicular diameter during ovulation monitoring was 16.37 mm. Ovulation rate at the follow up was 64.1% one month after treatment, 79.5% after three months and 82.9% after six months. 28 patients conceived during follow-up period. Pregnancy rate was 70.1%. Our study has shown that THL ovarian drilling improves ovulation and pregnancy rate in women with CC-resistant PCOS. We believe that this approach should be offered as second-line therapy at all PCOS CC-resistant women who fail the medical methods of ovulation induction.

[Comparison of fertiloscopy versus laparoscopy in the exploration of the infertility: analysis of the literature]

BACKGROUND

Fertiloscopy is a recent technique designed to explore the tubo-ovarian axis in unexplained infertility. It is a simple outpatient technique, allowing to perform operative procedures, but its position relative to laparoscopy is yet to be defined.

MATERIAL AND METHODS

A thorough and extensive bibliographical search was undertaken to fully embrace the question, challenging Medline at the National Library of Medicine, Cochrane Library, National Guideline Clearinghouse, Health Technology Assessment Database. All the retrieved articles were classified as either descriptive or comparative studies and evaluated on a set of criteria.

RESULTS

Most of the papers described case series coming from a few teams, focusing mainly on the technical aspect of the procedure, like the access rate to the posterior cul-de-sac, the success rate in visualizing the pelvis, the complications rate (mainly rectal perforation), and its operative performance in drilling ovaries for resistant polycystic ovarian syndrome. Comparative studies numbered six trials. They all followed the same design, fertiloscopy preceding conventional laparoscopy in patients taken as their own control. The concordance rate between the two modalities reaches 80% in terms of tubal pathology, adherences and endometriosis, with an estimated reduction of laparoscopies varying from 40% to 93%.

CONCLUSION

The current literature shows a concordance between fertiloscopy and conventional laparoscopic findings for certain parameters in cases of tubal pathology, adherences and endometriosis. The relative positions of these two modalities in unexplained infertility still remain elusive.

New developments in reproductive surgery

The introduction of in-vitro fertilisation within reproductive medicine has prompted questions to be asked about the relevance of reproductive surgery. Reproductive surgery is more than a competing discipline; it is complementary to the techniques of in-vitro fertilisation. As a complementary discipline, reproductive surgery covers the field of tubal and ovarian pathology and correction of uterine alterations. In recent decades, more attention has been paid to the importance of the uterus in the process of conception and implantation. The place of reproductive surgery and the existing controversies in the treatment of uterine congenital and acquired pathology, tubal, and ovarian surgery are discussed. Continuous training and accreditation programmes for reproductive technologies and surgery are more important than ever.

Incidence of sperm-immobilizing antibodies in infertile women with past Chlamydia trachomatis infection

PROBLEM

Among the risk factors for antisperm antibody production, inflammatory diseases of the genital tract are believed to play an important role. Chlamydia trachomatis infection is one of the most common sexually transmitted diseases. There are some reports suggesting that human sperm have antigens that cross-react immunologically with certain microbial antigens, such as C. trachomatis. However, this is still controversial. We performed a retrospective study to investigate the correlation between anti-chlamydial antibodies and sperm-immobilizing antibodies in infertile women.

METHOD OF STUDY

Between January 2007 and March 2009, the presence of sperm-immobilizing antibodies was examined by the sperm immobilization test using sera from 273 infertile women. Anti-chlamydial antibodies (IgG and IgA) were examined to prove past C. trachomatis infection by ELISA using the same sera from infertile women.

RESULTS

The overall incidence of sperm-immobilizing antibodies was 2.9% (8/273) in infertile women. The incidences of sperm-immobilizing antibodies were 6.4% (5/78) in cases with past C. trachomatis infection and 1.5% (3/195) in cases without past C. trachomatis infection. There was a significant difference between the two groups (P = 0.031).

CONCLUSION

A significantly higher incidence of sperm-immobilizing antibodies was noted in infertile women with past C. trachomatis infection compared with that of those without past C. trachomatis infection. This is the first demonstration that C. trachomatis infection could play a role in the production of sperm-immobilizing antibodies in infertile women.

Transvaginal hydrolaparoscopy by flexible fiberscope--a study of preliminary cases

Transvaginal hydrolaparoscopy (THL) has become a first-line procedure in infertile women, and THL by flexible fiberscope (THLF) is a less traumatic and a more suitable outpatient procedure than diagnostic laparoscopy. We performed THLF on infertile women based on four indications; (i) tubal obstruction and/or peritubal adhesion as suggested by hysterosalpingography (HSG); (ii) serum antibody against Chlamydia (C) positive for trachomatis; (iii) diagnosis of early stage endometriosis; and (iv) unexplained infertility. Seven women with a chief complaint of infertility were the subjects of the present study. Two of the 7 cases had a history of gynecological surgery. Six of 7 cases had a history of C. trachomatis infection. Four cases had abnormal findings of fallopian tubal patency in hysterosalpingography. Parafallopean tubal atresia and tubal obstruction were observed in 4 cases by THLF. In one case the bilateral ovaries were extremely small and atrophic. None of the cases had serious complications after THLF. After the THLF, six women were able to have a baby by assisted reproductive technology (ART) within two years. As THL was developed using a solid scope, indications for THL have been limited, and have excluded cases with retroverted uterus or peritoneal surgical history. In the present study, THL using a fiberscope was carried out in infertile women with retroverted uterus, and in women with a history of peritoneal cavity surgery to examine the feasibility of extending the indications for THL. Findings on the THLF were given precedence in deciding further treatment strategies. We believe that THLF can be useful in helping patients with these indications to successfully achieve early pregnancy. This study is the first trial of THLF.

Evaluation of the tissue damage of porcine ovaries after bipolar drilling under transvaginal hydrolaparoscopy--an in vitro experiment

OBJECTIVE

To evaluate the tissue damage of in vitro porcine ovarian drilling in saline solution mimicking transvaginal hydrolaparoscopy (THL).

STUDY DESIGN

In vitro ovarian drilling with different current and activation time was applied on fresh porcine ovaries, 15 ovaries in each group and 2 punctures in each ovary. Drilling using 5-Fr bipolar needle was performed in saline solution mimicking THL, while saline solution rinsing the ovaries after monopolar electrocoagulation.

RESULTS

The monopolar drilling caused more tissue damage than the bipolar needle in saline (p < 0.01). The ratio of the damage of monopolar electrocoagulation (40 w, 3s) over that of bipolar diathermy in saline solution (70 w, 15 s) was 7.4 [(16.74 +/- 1.30) mm(3)/(2.27 +/- 0.49) mm(3)]. In the bipolar groups, the 70 w power set (15s and 20 s) caused significantly more tissue damage than the 50 w ones (p < 0.05), and the amount of damage was not stimulation time dependent (p > 0.05).

CONCLUSION

The tissue damage caused by monopolar electrocoagulation with 40 w for 3 s was about seven times of that caused by 5-Fr bipolar one in saline with 70 w for 15 s . In THL drilling using a 5-Fr bipolar electrode, the current is more crucial than stimulation time.

Major complications and outcome of diagnostic and operative transvaginal hydrolaparoscopy

AIM

Transvaginal hydrolaparoscopy (THL) has recently been developed as a less invasive alternative to conventional laparoscopy. There are some reports that described the usefulness and prognostic value of diagnostic THL in infertile women. Moreover, operative THL such as ovarian drilling for unovulatory women with polycystic ovarian syndrome (PCOS) to induce ovulation has also been found to be as effective as that by conventional laparoscopy. The risk of bowel injury and sepsis by transvaginal access with culdoscopy was higher than that with laparoscopy in the previous reports. The purpose of the present study was to examine the risk of diagnostic and operative THL according to two case studies with a literature review.

METHODS

The authors carried out diagnostic or operative THL in 177 infertile women, aged 22-43 years. Major complications during THL and a review of the literature were analyzed.

RESULTS

Two cases of bowel injury were diagnosed during diagnostic THL. No complication occurred during operative THL. In total, the incidence of bowel injury was 1.1%. The injuries were diagnosed during THL and treated expectantly under strict conditions in both cases. Ten studies in the literature reported a total of 4232 procedures, including 26 bowel injuries (0.61%) and one perforation of a retroflexed uterus (0.02%).

CONCLUSIONS

The usefulness of THL for diagnostic and operative purposes is in no doubt. However, informed consent should be obtained and vigilance before and during THL should be maintained, although it can be done on an outpatient clinic basis.

Transvaginal hydrolaparoscopy, its history and present indication

The investigation of the infertile couple by hysterosalpingography and laparoscopy is currently a highly debated issue. The purpose of this paper is to review whether transvaginal hydrolaparoscopy (THL), a new culdoscopic approach, in combination with minihysteroscopy and chromopertubation test can be offered as a complete one-stop endoscopic exploration. The technique allows complete endoscopic exploration of the reproductive tract in an office or outpatient setting and has been validated during the past years for its accuracy, safety and patient tolerance. Although further prospective randomized studies are required to prove the superiority and cost-benefit of transvaginal hydrolaparoscopy as diagnostic tool in comparison with hysterosalpingography (HSG) and laparoscopy, the technique can be proposed as a safe first-line investigation predicting the fertility outcome in women.

Prevalance of Chlamydia trochomatis, Ureaplasma urealyticum and Mycoplasma hominis infections in the unexplained infertile women

OBJECTIVE

To prospectively investigate the prevalence of Chlamydia trachomatis (CT), Mycoplasma hominis (MH) and Ureaplasma urealyticum (UU) in the cervical canal and pouch of Douglas in unexplained infertile women and compare it to healthy controls in the Turkish population.

MATERIALS AND METHODS

A total of 31 women presenting with a history of infertility [n = 24 (77%) primary infertility, n = 7 (23%) secondary infertility] between 20 and 38 years of age and 31 women willing to have tubal ligation between 30 and 41 years of age were consecutively included into this study. Specimens were taken from intra-abdominal washings and from the cervical canal. CT, MH and UU were detected with polymerase chain reaction (PCR).

RESULTS

Results of 62 women were analyzed. None of the participants met the criteria for salpingitis during laparoscopy. The most common infection in the cervical canal in both groups was UU, which was detected in 13 cases of infertile patients and 11 controls (P = 0.602). Cervical chlamydial and mycoplasmic infection was detected in one case each in infertile and control patients. Neither MH nor UU were obtained from the pouch of Douglas in both groups. Only CT was present in peritoneal fluid of an infertile woman who had also a concomitant chlamydial infection in the cervical canal.

CONCLUSION

Demonstration of cervical colonization of CT by PCR may be a promising method for the detection of asymptomatic pelvic infection in patients with unexplained infertility. However, screening for MH and UU is not cost-effective due to similar low rates of detection.

Postoperative endocrine alterations and clinical outcome of infertile women with polycystic ovary syndrome after transvaginal hydrolaparoscopic ovarian drilling

Transvaginal hydrolaparoscopic ovarian drilling (THLOD) appears to be an effective minimally invasive procedure to induce ovulation in women with polycystic ovary syndrome (PCOS). Postoperative endocrinological alterations following THLOD show significant decrease of serum LH and testosterone concentrations.

Feasibility and clinical significance of endoluminal assessment by transvaginal salpingoscopy during transvaginal hydrolaparoscopy in infertile women

STUDY OBJECTIVE

To investigate the feasibility and clinical usefulness of transvaginal salpingoscopy (TS) during transvaginal hydrolaparoscopy (THL) in infertile women.

DESIGN

Retrospective study (Canadian Task Force classification II-3).

SETTING

Jichi Medical School, Tochigi, Japan.

PATIENTS

One hundred thirty infertile women, aged 22 to 43 years, who underwent THL.

INTERVENTIONS

Transvaginal salpingoscopy findings in comparison with THL findings.

MEASUREMENTS AND MAIN RESULTS

Transvaginal salpingoscopy could be performed in 41.0% of the attempted tubes. In comparing rates of successful TS in relation to tubal patency, tubal morphology, and past Chlamydia trachomatis infection, patent tubes and normal-appearing tubes classified with normal morphology had a significantly higher TS success rate. However, past C. trachomatis infection did not affect the success of TS. There was a significant correlation between salpingoscopic and laparoscopic findings; however, there were no significant correlations between salpingoscopic findings and C. trachomatis antibody titers.

CONCLUSIONS

These findings suggest that TS can be performed simultaneously in some infertile women undergoing THL especially those with patent tubes or with normal-appearing tubes. Further studies are required to show the usefulness of intratubal exploration in assessing tubal infertility.

Transvaginal laparoscopy

Transvaginal laparoscopy (TvL) offers an alternative to standard diagnostic laparoscopy in subfertile patients without obvious pelvic pathology. With a specially developed needle-trocar system, access to the pouch of Douglas is gained through a needle puncture of the posterior fornix. Performed under local anaesthesia or sedation with the patient in a dorsal decubitus position and using prewarmed Ringer lactate as a distension medium, TvL allows complete exploration of the tubo-ovarian structures without supplementary manipulation. The combination of transvaginal sonography and transvaginal endoscopy, including minihysteroscopy, TvL, salpingoscopy and chromopertubation test, permits the most complete exploration of the reproductive tract and can be used as a first-line investigation of female fertility in a one-stop infertility clinic. As the transvaginal route offers easy access to the tubes, ovaries and fossa ovarica, some operative procedures are possible. However, in the absence of a panoramic view, these will be limited to minor interventions.

Successful pregnancy following conservative treatment of massive ascites associated with acute Chlamydia trachomatis peritonitis

It is well known that Chlamydia trachomatis causes acute and chronic pelvic inflammatory disease including salpingitis. We describe a case of successful pregnancy following conservative treatment of massive ascites associated with acute Chlamydia trachomatis peritonitis. In this present case, we conservatively treated a woman with acute chlamydial salpingitis accompanied with marked ascites and an adnexal mass that simulated a malignant neoplasm. Elevated CA125 and CA19-9 also suggested a malignancy at the time of diagnosis, however following treatment they decreased to below the cut-off value, and were useful in identifying the efficacy of medical treatment. The patient subsequently became pregnant after infertility treatment and underwent a normal vaginal delivery. We conclude that the possibility of Chlamydia trachomatis peritonitis should be considered when a patient presents with ascites and an adnexal mass in sexually active women. (Reprod Med Biol 2004; 3: 217-221).

Progress in transvaginal hydrolaparoscopy

Reproductive performance is now more than ever determining the choice of treatment for each individual couple. The easy access to ART treatments, their financial benefits, and the relative high success rate per cycle are at the basis of a liberal referral to these treatments without an accurate diagnosis. The easy and comprehensive investigation by a transvaginal endoscopy as a first-line diagnostic procedure allows for an accurate diagnosis and the choice of the most appropriate treatment.

Relationships between Chlamydia trachomatis Antibody Titers and Tubal Pathology Assessed using Transvaginal Hydrolaparoscopy in Infertile Women

PROBLEM

Since transvaginal hydrolaparoscopy (THL) was introduced as the first-line procedure in the early stages of the exploration of the adnexal structures in infertile women, it has been shown that THL is a less traumatic and a more suitable outpatient procedure than diagnostic laparoscopy. This study was performed to investigate the relationships between Chlamydia trachomatis antibody titers and tubal pathology assessed using THL in infertile women.

METHODS

The C. trachomatis antibody titers (IgG and IgA) were evaluated by ELISA. The posterior of the uterus and the tubo-ovarian structures were carefully observed, and tubal passage using indigocarmine was confirmed using THL. THL was carried out in 32 infertile women having C. trachomatis antibody in their sera between May 1999 and October 2001. Unilateral salpingectomy had been performed on two of the 32 patients.

RESULTS

Tubal occlusion was confirmed in 20 (32.3%) of the 62 tubes, while peritubal adhesion was diagnosed in 37 (59.7%) of the 62 tubes. Using receiver operating characteristics curves, the cut-off value of C. trachomatis IgG antibody titer to predict tubal occlusion was determined to be 3.55. Tubal occlusion was observed in 16 (51.6%) of the 31 tubes in patients with the C. trachomatis IgG antibody titer of more than 3.55, which was significantly higher in four (12.9%) of the 31 tubes having the antibody titer less than 3.55 (P = 0.004). However, there was no correlation between C. trachomatis IgG antibody titer and peritubal adhesion. As for C. trachomatis IgA antibody titer, there was no correlation between antibody titer and tubal occlusion or peritubal adhesion.

CONCLUSIONS

These results suggest that C. trachomatis infection is significantly associated with tubal pathology. Although the cut-off value of C. trachomatis IgG antibody titer to predict the existence of tubal occlusion was shown to be 3.55, we would suggest that THL or standard laparoscopy is performed to consider appropriate treatments in patients with past C. trachomatis infection because of the high prevalence of peritubal adhesion.

Chemokine bioactivity of RANTES is elevated in the sera of infertile women with past Chlamydia trachomatis infection

PROBLEM

It has been shown that Chlamydia trachomatis infection in infertile women is highly associated with tubal pathology. Chlamydia trachomatis antibody testing is a simple screening test for tubal factor subfertility, however, it is based on the detection of previous infection. Recently, association between some inflammatory diseases and chemokines has been investigated. This study was performed to clarify the relationship between chemokines in the sera of infertile women and past C. trachomatis infection.

METHOD OF STUDY

Serum samples were collected from 10 infertile women having C. trachomatis antibodies [immunoglobulin (Ig)G and/or IgA] in their sera and 10 infertile women without the antibodies. All patients' tubo-ovarian structures were explored by transvaginal hydrolaparoscopy (THL). A CXC chemokine, interleukin-8, and six CC chemokines including macrophage inflammatory protein-1alpha (MIP-1alpha), MIP-1beta, monocyte chemotactic protein-1 (MCP-1), MCP-3, eotaxin, and regulated on activation, normal T cell expressed and secreted (RANTES) concentrations in their sera were analyzed using enzyme-linked immunosorbent assay.

RESULTS

The serum concentration of RANTES was significantly higher in patients with C. trachomatis antibodies than those without the antibodies (P = 0.019). However, there were no significant differences of the concentrations of other chemokines between the sera of infertile women with and without C. trachomatis antibodies. The concentration of RANTES in the sera of infertile women did not correlate with C. trachomatis antibody titers or tubal pathology diagnosed by THL.

CONCLUSIONS

These findings might indicate significant roles of some chemokines in the pathogenesis of C. trachomatis infection. Further studies are necessary to study the usefulness of evaluations of chemokines in tubal infertility investigations.

Application of transvaginal hydrolaparoscopy for ovarian drilling using Nd:YAG laser in infertile women with polycystic ovary syndrome

Since transvaginal hydrolaparoscopy (THL) was introduced as the first-line procedure in the early stage of the exploration of the tubo-ovarian structures in infertile women, it has been shown that THL is a less traumatic and a more suitable outpatient procedure than diagnostic laparoscopy. In the present study, a minimally invasive surgery was carried out in infertile women with polycystic ovary syndrome (PCOS) by THL. Ovarian drilling using Nd:YAG laser vaporization by THL was performed in two clomiphen citrate-resistant infertile women with PCOS. After ovarian drilling with THL, a patient recovered an ovulatory cycle. These findings suggest that ovarian drilling by THL seems to be a safe procedure in infertile women with PCOS. However, further investigations are required to evaluate the effectiveness and risks of this minimally invasive operation. (Reprod Med Biol 2003; 2: 37-40).

Usefulness and prognostic value of transvaginal hydrolaparoscopy in infertile women

OBJECTIVE

To evaluate the usefulness and prognostic value of transvaginal hydrolaparoscopy (THL) in infertile women.

DESIGN

Retrospective study.

SETTING

Jichi Medical School Hospital, Tochigi, Japan.

PATIENT(S)

Thirty-six patients who were followed up for 6 months or longer after THL was performed.

INTERVENTION(S)

Transvaginal hydrolaparoscopy findings in comparison with hysterosalpingography (HSG).

MAIN OUTCOME MEASURES

Transvaginal hydrolaparoscopy findings, HSG findings, treatment strategy, and prognosis.

RESULT(S)

Twenty of 36 patients (55.5%) became pregnant, including 7 by coitus, 7 by artificial insemination with the husband's semen, and 6 by assisted reproductive technology (ART). In 11 of these pregnant patients, information obtained during THL differed from findings on HSG.

CONCLUSION(S)

Transvaginal hydrolaparoscopy is useful in selecting a future treatment strategy.

Transvaginal hydrolaparoscopy: a new diagnostic tool in infertility investigation

BACKGROUND

To establish the value of a new technique called transvaginal hydrolaparoscopy for exploration of the tubo-ovarian structures in the management of patients with unexplained infertility.

METHODS

A total of 120 women with primary or secondary infertility, and without obvious pelvic pathology, were included in the study. The first 14 patients received general anesthesia and underwent transvaginal laparoscopy immediately before standard laparoscopy. The remaining 106 patients had transvaginal laparoscopy performed under local anesthesia, with standard laparoscopy performed only on those with pathology, which required operative intervention. Information on pathology, complications, and successful access to the pouch of Douglas were recorded.

RESULTS

The successful rate of access was 93%. Pathology was found in 29 patients, of whom 15 required operative laparoscopy. Also, out of 19 patients with adhesions, 11 (58%) had normal dye test bilateral, and only two (11%) had bilateral occlusion of the tubes. No complications were observed.

CONCLUSION

Transvaginal hydrolaparoscopy is a safe and well-tolerated method for investigating the tubo-ovarian structures in unexplained infertility. It is superior to hysterosalpingography for diagnosis of adhesions.

One-stop endoscopy-based infertility clinic

PURPOSE OF REVIEW

The investigation of the infertile couple is currently a highly debated issue. The purpose is to review whether transvaginal hydrolaparoscopy in combination with mini-hysteroscopy and chromopertubation can be offered as a one-stop infertility investigation.

RECENT FINDINGS

The technique is based on the direct visualization of the reproductive organs and the presence of tubal patency, and has been clinically validated during the past year for its accuracy, safety and patient tolerance.

SUMMARY

Further prospective randomized studies are required to prove the superiority of transvaginal hydrolaparoscopy in comparison with hysterosalpingography as a first-line investigation in predicting the fertility outcome.
