RESUMEN

Salpingo-enteric fistula is a rare condition that can cause infertility. It occurs when there is an abnormal connection between the fallopian tube and the intestine. Accurate diagnosis can be made using hysterosalpingography.The case of a 40-year-old asymptomatic woman diagnosed with primary infertility and scheduled for a hysterosalpingogram as part of the routine workup in the infertility clinic. There was no history of pelvic inflammatory disease or previous surgical intervention. The result showed presence of bilateral hydrosalpinx without peritoneal spillage. Contrast leaked into the adjacent descending colon and sigmoid loop on the left side. Asymptomatic salpingo-enteric fistulas may be a hidden cause of infertility, and their association can only be confirmed if all other factors of infertility have been convincingly ruled out.

RESUMEN

Salpingo-enteric fistula is a rare disease causing infertility. It occurs when there is a connection between fallopian tube and the intestine. It can be accurately diagnosed with hysterosalpingography. Fistulas mostly occur as a consequence of obstetric complications, however, inflammatory bowel disease, pelvic malignancy, pelvic radiation therapy, iatrogenic causes, and trauma are other potential causes. The possibility of tuberculous salpingitis as a possible cause of salpingo-enteric fistula should always be considered in the developing countries where tuberculosis is endemic.

RESUMEN

OBJECTIVES: To determine the detection rates of hysterosalpingogram (HSG), transvaginal 2D ultrasound (TV 2D US), transvaginal 3D ultrasound (TV 3D US) in diagnosing of incomplete uterine septum (IUS) and significant arcuate uterine anomaly (AUA). METHODS: This retrospective cohort study included patients with infertility or recurrent pregnancy loss (516) that were found to have IUS (317) or significant AUA (199) on diagnostic hysteroscopy (DHS). We compared the detection rate of the various radiological tests in all patients with documented IUS or AUA on DHS. RESULTS: The diagnosis of IUS and AUA was made in 49.7% on HSG, 54.2% on TV 2D US and 69.5% on TV 3D US. When both HSG and TV 2D US or HSG and TV3D US were used, the diagnosis was correct in 67.7% and 82.6% of patients, respectively. CONCLUSION: Although HSG, TV 2D US, TV 3D US are useful in the screening for IUS/AUA, none of these imaging tests alone or in combination are accurate enough to rule out the diagnosis of such congenital uterine anomalies. In patients with a history of infertility or RPL and negative radiologic tests, DHS is the only reliable method to rule out IUS or significant AUA.

RESUMEN

We experienced a case of pregnancy after hysterosalpingogram and residual lipiodol in the extraperitoneal space. Initially, we suspected a metallic remnant; however, analysis by mass spectrometer confirmed that it was a remnant of lipiodol.

RESUMEN

PURPOSE: To determine outcomes after successful fallopian tube recanalization (FTR) in women who suffer infertility with documented tubal occlusion on hysterosalpingogram. METHODS: A retrospective review of consecutive successful FTR procedures from January 2010 to December 2016 was performed. 53 women who had hysterosalpingogram confirmed unilateral or bilateral tubal occlusion from a single tertiary academic medical center and successful FTR were eligible for inclusion. 35 (66.0%) patients had follow up at 12 months after FTR, with 13 conceiving within 1 year of the procedure. Data was collected from the medical record. Complication, conception, and take-home-baby (THB) rates were recorded. The average age of patients was 32.3 years (range 26-42 years). All patients received peri- and post-procedure antibiotics. The study was conducted with institutional IRB approval. RESULTS: Average follow-up after FTR was 1335 days. All patients tolerated the procedure well with no immediate complications. One patient had a urinary tract infection a week after FTR. 13 (37.1%) became pregnant after FTR. Of these women, 2 had ectopic pregnancies and 2 patients had spontaneous abortions. The THB rate after FTR for all patients was 25.7%. The THB rate in women who became pregnant after FTR was 69.2%. Of those women who did not become pregnant after FTR, 19 (84.6%) went to assisted reproductive techniques, and of those, 8 (42.1%) became pregnant. CONCLUSION: Infertility affects 8.4% of U.S. women, with tubal disease a major causative factor. In our study, successful FTR led to pregnancy in over a third of the patients with the majority giving birth to healthy babies. Given the success of obtaining pregnancy in combination with a low complication rate, FTR is a viable option in women who suffer from tubal infertility.

RESUMEN

Recent interest in the use of oil-soluble contrast media (OSCM) for hysterosalpingography (HSG) and other tubal flushing procedures is largely the result of publication of the large, multicentre, randomized controlled H2Oil trial in the New England Journal of Medicine in 2017, addressing the long-held suspicion that pregnancy rates following HSG with OSCM are higher than if a water-soluble contrast media (WSCM) is used. However, the findings of this trial have been compromised by the WSCM selected for comparison with OSCM. The chosen WSCM belongs to a superceded class of ionic media, with an iodine concentration, osmolality and viscosity all lying at the extreme end of the range for water-soluble radiographic contrast. The requirement for safe, cheap, versatile WSCM for intravascular use during computerized tomography, angiography and interventional procedures has resulted in considerable refinement of WSCM, with current widespread use of non-ionic, low osmolality or iso-osmolar WSCM in radiology, including for HSG. However, the use of the earlier ionic, high osmolality agents such as that selected for the H2Oil trial persists for HSG in some centres, despite potential adverse effects on the endometrium and fallopian tubal epithelium compared with more modern, less toxic WSCM. Knowledge of the variety of physical and chemical characteristics of the available WSCM is essential for interpretation of the current literature and establishing the most effective and safe water-soluble agent to use for HSG. Design of future clinical trials to establish the potential superiority of OSCM over WSCM for fertility enhancement must include the use of the readily available, inexpensive modern WSCM. While the fertility rates following OSCM HSG have been shown to be high in women with idiopathic infertility, more robust trials are required before the widespread use of OSCM for HSG or other modalities such as ultrasound and laparoscopy should be adopted.

RESUMEN

Assessment of tubal patency and therapeutic tubal flushing using Lipiodol, an oil-soluble contrast media (OSCM), has been shown to enhance fertility, resulting in increased interest in the use of Lipiodol. A modified hysterosalpingogram (HSG) technique, including a supplementary ultrasound with the contrast in situ, is recommended when using Lipiodol, taking into account both safety issues and technical challenges specific to Lipiodol.

RESUMEN

BACKGROUND: Few cases with fistulous communication between the GI system and female adnexal structure have been reported in the literature, and bilateral contrast spillage has been reported only in one case, and this case is the second one all over the world. CASE PRESENTATION: The case was a 27-year-old woman with a diagnosis of primary infertility. She was booked with hysterosalpingogram (HSG) as part of the routine workup in the infertility clinic. There was a positive history of pelvic surgery for bilateral adnexal cysts for her in 2014. In this case, previous pelvic surgery without any medical problems was the strongest risk factor for tubo-intestinal fistula. Cystectomy performed for the left adnexal cyst and the right adnexal cyst was only drained. The pathologic report for the left ovarian cyst was endometriosis. HSG result showed evidence of bilateral fallopian tube opacification with contrast outlining from the fallopian tubes. Contrast leakage happened to the adjacent small intestine in the right side and peritoneal cavity on the left side. CONCLUSION: Fistulous connections between fallopian tube and intestine will remain an exceptional rarity. The reported case could be a good lesson illustrating that the adherence to general surgical principles (meticulous hemostasis, careful applying of diathermy, etc.) and a watchful postoperative care could protect the patient from both usual and unusual complications.

RESUMEN

Infertility is a public health concern worldwide. Hysterosalpingogram is a useful diagnostic tool to both evaluate the contours of the uterine cavity and to assess tubal patency. Intrauterine devices (IUDs) are the world's most prevalent form of long-acting reversible contraception. In this case, a 30-year-old P0 female, an immigrant from Jamaica, was referred for hysterosalpingogram for primary infertility workup. Under fluoroscopic imaging, an unexpected T-shaped IUD was visualized in the expected location of the uterus. The IUD lacked portions of the radiopaque copper lining. The patient initially denied IUD insertion. However, after further investigation, the patient's mother admitted IUD insertion at the age of 14 in Jamaica. This case raises a concern for the possibility of unexpected IUD discovery during infertility work up and emphasizes the importance of clinician awareness of the changes that may be seen on imaging when these devices are in place long-term.

RESUMEN

BACKGROUND: Lipiodol is an oil-based solution commonly used in hysterosalpingogram (HSG), but not hysterosalpingo contrast sonography (HyCoSy). In women with unexplained infertility, evidence suggests that tubal flushing with Lipiodol results in improved fertility post-procedure. We propose that Lipiodol can be visualised under ultrasound similar to commonly used saline, and hence utilised for HyCoSy, allowing the benefit of an oil-based tubal flushing to occur with HyCoSy. AIMS: To examine whether Lipiodol is visible sonographically, assess optimal agitated Lipiodol mix and ultrasound settings for visibility, and compare visibility to agitated saline, routinely used for HyCoSy. MATERIALS AND METHODS: Two separate sonographers with identical ultrasound machines and model pelvises recorded images with varying degrees of agitated Lipiodol and ultrasound settings, in addition to capturing images with no fluid and agitated saline. Each test was performed in quadruplicate and in random order. Images were read by 47 blinded reporters and visibility reported on a scale of one (not visible) to five (clearly visible). RESULTS: The mean visibility score for images captured where the Lipiodol sample was agitated five times prior to injection to allow the formation of air microbubbles, regardless of ultrasound setting, were higher than or not different from that for agitated saline (all P > 0.7 when not different, <0.001 when higher). CONCLUSIONS: Sonographic visualisation of agitated Lipiodol is similar or better than that of agitated saline. Lipiodol may therefore present a possibility for use with HyCoSy, with the added benefit of oil-based tubal flushing, avoiding the radiation exposure of HSG and concurrently providing pelvic soft-tissue evaluation.

RESUMEN

Infertility, or subfertility, is the inability to achieve a clinical pregnancy after a 1-year period of regular unprotected sexual intercourse in women younger than 35 and after 6 months in women older than 35. Although initial assessment involves a multitude of factors, including a detailed medical history, physical examination, semen analysis, and hormonal evaluation, diagnostic imaging of the female partner often plays an important role in establishing the etiology for infertility. This article provides an overview of the multimodality imaging assessment of female infertility and details the developmental and acquired pelvic abnormalities in which diagnostic imaging aids in evaluation.

RESUMEN

INTRODUCTION: Radiographer role development has touched boundaries across the multidisciplinary team and more recently branched into the field of gynaecology. Radiographers are now able to perform tasks that were traditionally performed by radiologists and gynaecologists to implement a radiographer-led Hysterosalpingogram (HSG) service. The aims of the study were to (i) implement a radiographer-led HSG service with a view to decreasing waiting times. (ii) To determine ladies perceptions and satisfaction levels. METHOD: Local clinical guidelines were developed with the radiologist/gynaecologist and trainee HSG radiographers. A robust system of work was initiated which required maintaining comprehensive log books to record examinations performed and reports written. These were audited and compared with those of the radiologist. Audit cycles were monitored through Q Pulse to ensure good practise was maintained. Patient satisfaction surveys were developed and distributed to 100 consecutive ladies attending for HSG over a 6 month period from January-July 2017. RESULTS: The radiographer-led service has increased the number of appointment slots offered for HSG's throughout the year as the service now runs every week. HSG's were performed by 5 staff members but now only require 3 staff. A 75% response rate was achieved from the questionnaire survey and shows high patient satisfaction levels. Ladies reported being better informed about their examination resulting in decreased anxiety, concerns and discomfort. CONCLUSION: The implementation of this service has successfully reduced waiting lists for HSG examinations from 14 to 0 weeks. The Trust has saved £15,000 on staff salaries per annum since the service started.

RESUMEN

BACKGROUND: Fallopian tube occlusion is a common cause of infertility, but the effect of unilateral tubal block (UTB) on pregnancy rates (PR) after controlled ovarian hyperstimulation and intrauterine insemination (COH-IUI) remains controversial. OBJECTIVE: To evaluate PR after COH-IUI among infertile women with proximal and distal UTB diagnosed by hysterosalpingogram (HSG), compared against women with bilateral patent tubes experiencing unexplained infertility. SEARCH STRATEGY: We searched EMBASE, MEDLINE, Google Scholar, Cochrane Library, and PUBMED from inception to 14 January 2018. SELECTION CRITERIA: Studies that report PR/cycle or cumulative PR among women with UTB and controls were included. DATA COLLECTION AND ANALYSIS: Two authors independently selected and extracted study characteristics and data. Methodological quality was assessed using the Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) guidelines. MAIN RESULTS: Among 2965 patients and 5749 IUI cycles across ten studies, no significant difference in PR/cycle (odds ratio, OR = 0.88; 95% confidence interval, 95% CI = 0.69-1.12) and cumulative PR (OR = 0.80, 95% CI = 0.62-1.04) was observed. Patients with proximal UTB demonstrated similar PR/cycle (OR = 1.06, 95% CI = 0.68-1.66) and cumulative PR (OR = 1.10, 95% CI = 0.75-1.62), compared with controls, whereas patients with distal UTB had significantly lower cumulative PR (OR = 0.49, 95% CI = 0.25-0.97, P = 0.04). Patients with proximal block also demonstrated significantly improved cumulative PR, compared with patients with distal block (OR=2.41, 95% CI = 1.37-4.25, P = 0.002). CONCLUSION: Infertile patients with proximal UTB diagnosed by HSG can expect similar pregnancy rates after COH-IUI, compared with those with bilateral tubal patency and unexplained infertility, whereas patients with distal UTB have lower odds of pregnancy. These differences may reflect inherent diagnostic limitations of HSG or differences in underlying pathologies. TWEETABLE ABSTRACT: Meta-analysis evaluates pregnancy outcomes after COH-IUI in women with unilateral tubal block diagnosed by HSG.

RESUMEN

PURPOSE: The objectives of our study included comparing reproductive histories and causes of infertility between patients with and without a hysterosalpingogram (HSG) investigation, and summarizing the prevalence and extent of tubal abnormalities among patients who underwent HSG. Outcomes following assisted reproductive technology (ART) were compared between HSG and non-HSG groups. MATERIALS AND METHODS: A cross-sectional study was conducted to review the medical records of 200 Saudi women with subfertility. In addition to information on HSG, patient data extracted included age, body mass index (BMI), infertility duration, miscarriage experience, parity, cause of infertility, and history of previous surgery, ectopic pregnancy, endometriosis, tubal surgery, pelvic inflammatory disease (PID), in vitro fertilization (IVF), intracytoplasmic sperm injection (ICSI), pregnancy, and live birth. RESULTS: One hundred and ninety six (98.0%) patients had either IVF (n=18; 9.0%) or ICSI (n=178; 89.0%) performed; ICSI was performed in 157 (90%) and 21 (81%) patients. Of the 12 women with tubal factor who did not undergo HSG, 3 (25.0%) became pregnant after ART, 8 (66.7%) did not, and the status of 1 (8.3%) is yet unknown. CONCLUSIONS: Our study aimed to contribute to resolving the debate regarding the continuing role of HSG in an environment where ART has become established as a successful approach to treat infertility. Most of the HSGs were done as per the attending physician's discretion, and not according to any specific policy.

RESUMEN

STUDY OBJECTIVE: To assess if follow-up confirmation testing 3 months after hysteroscopic sterilization with the Essure device (Bayer HealthCare Pharmaceuticals, Inc., Whippany, NJ) improved with recommendation for transvaginal ultrasound (TVUS) versus hysterosalpingogram (HSG). DESIGN: Retrospective, observational case-controlled cohort study (Canadian Task Force classification II-2). SETTING: Two-physician private practice in Evansville, Indiana. PATIENTS: Compliance rates for a TVUS confirmation test on 100 women who underwent hysteroscopic sterilization compared with a previously published cohort of 1004 women who were scheduled to undergo an HSG confirmation test. INTERVENTION: Acquisition of 3-month confirmation testing after Essure hysteroscopic sterilization. MEASUREMENT AND MAIN RESULTS: All women who underwent Essure hysteroscopic sterilization with recommendation for TVUS confirmation testing between July 2015 and January 2017 were compared with a previously published cohort of 1004 patients with recommendation for HSG confirmation testing (HSG cohort). In addition, an HSG subgroup cohort (HSG subgroup) similar in size and closest chronology to the TVUS cohort was drawn from the original 1004 patients and analyzed for HSG follow-up. Records for all patients were reviewed for demographic, procedural, and confirmation testing and outcome data. One hundred patients were identified with successful Essure device placement and a recommendation for TVUS confirmation testing. Eighty-eight patients (88.0%) returned for TVUS at 3 months. In the HSG cohort 1004 successful Essure devices were placed, and 778 patients returned for the recommended HSG follow-up (77.5%). There was a significantly higher follow-up rate for TVUS compared with the HSG cohort (88.0% vs 77.5%, p = .008). In the HSG subgroup 184 patients were identified, and 133 patients presented for HSG follow-up (72.3%), indicating a significantly higher follow-up rate in the TVUS cohort (88.0% vs 72.3%, p = .001). No pregnancies after any confirmation testing were noted. CONCLUSION: Confirmation testing with TVUS rather than HSG 3 months after Essure device placement results in increased patient compliance that may lead to improved patient outcomes with reduction of unintended pregnancy.

RESUMEN

OBJECTIVE: To demonstrate a novel approach to office tubal patency assessment through infusing air into saline during flexible office hysteroscopy. We also provide data addressing pain and patient experience relative to hysterosalpingography (HSG). DESIGN: Video presentation of clinical technique with supportive crossover data (Canadian Task Force classification II-1). Its University of Mississippi Medical Center Institutional Review Board protocol number is 2013-0230. SETTING: Academic hospital. PATIENT(S): Women undergoing office hysteroscopy and ultrasound, with a subset also having HSG. INTERVENTION(S): Air infusion into saline during office hysteroscopy. MAIN OUTCOME MEASURE(S): The focus is on demonstrating how the technique appears and is performed, with supplemental Likert data addressing subjective pain and preference relative to HSG. RESULT(S): When performed as described, this office technique has 98.3%-100% sensitivity to tubal occlusion and 83.7% specificity. The gentle technique is central to accurate outcomes, which is facilitated through use of a small-caliber (<3 mm), flexible hysteroscope and avoiding uterine overdistention. Patients are far more likely to report maximum discomfort with HSG. Among patients who also had HSG, 92% somewhat or strongly prefer hysteroscopic assessment. Also, 96% of patients reporting maximum discomfort with HSG had mild to no discomfort with the described technique. CONCLUSION(S): Air-infused saline at flexible office hysteroscopy can accurately, gently, and rapidly assess tubal patency. Coupled with strong patient preference for this technique over HSG, it is a promising option for evaluating fertility. CLINICAL TRAIL REGISTRATION NUMBER: NCT02005263.

RESUMEN

STUDY OBJECTIVE: To determine whether air bubbles infused into saline during flexible office hysteroscopy can accurately predict tubal patency. DESIGN: Diagnostic accuracy study (Canadian Task Force classification II-1). SETTING: An academic hospital. PATIENTS: Women undergoing office hysteroscopy and ultrasound. INTERVENTIONS: Air infusion into saline during office hysteroscopy. MEASUREMENTS AND MAIN RESULTS: The primary outcome measures were whether air bubbles traverse the ostia at hysteroscopy, whether there is patency at abdominal surgery, and the rate of cul-de-sac (CDS) fluid accumulation from office hysteroscopy. Four hundred thirty-five patients underwent office hysteroscopy with air infusion, 89 of whom also had abdominal surgery. Depending on interpretation, sensitivity to tubal occlusion was 98.3% to 100%, and specificity was 83.7% with standard chromopertubation pressures; 95.3% to 100% of the time proximal patency was observed, whole tubal patency was observed through chromopertubation for patients with surgical data. Changes in CDS fluid volume from before to after office hysteroscopy were also used as an indirect proxy for tubal patency. Patients with risk factors for occlusion such as known or suspected tubal disease, known or suspected adhesions, and sonographic identification of adhesions through the sliding sign were all less likely to demonstrate a change in CDS fluid volume after hysteroscopy than women without these risk factors (p < .0001). Bilateral dispersion of air bubbles during hysteroscopy better predicted shifts in CDS volume than these risk factors and demonstrated shifts comparable with bilateral patency at laparoscopy (p < .001). CONCLUSION: Air-infused saline at office hysteroscopy can accurately assess tubal patency. Additionally, bilateral patency identified through office hysteroscopy may predict bilateral patency at surgery better than several commonly used historic and sonographic variables.

RESUMEN

OBJECTIVE: We hypothesize that the shape of the Essure microinsert on ultrasound is able to predict complications evident on hysterosalpingogram (HSG), the accepted gold standard. METHOD AND MATERIALS: From July 2, 2009 to July 2, 2012, 441 women at our institution received Essure microinsert placement for the purpose of permanent sterilization. 2D and 3D coronal plane transvaginal ultrasounds were performed three months after Essure microinsert placement. Those patients with complications identified on ultrasound, a non-diagnostic ultrasound, or following a difficult insertion were referred for HSG. Patients with both HSG and ultrasound performed were retrospectively selected and anonymized. The ultrasounds were reviewed by a single, blinded radiologist. A total of 122 microinserts in 65 patients were described on ultrasound using a numeric grading system and compared to HSG findings. RESULTS: Microinsert placement resulted in 37 complications, 31 of which were identified on ultrasound, including uterine and tubal perforations and placement in the endometrial cavity. The sensitivity of Essure microinsert shape on ultrasound in predicting complications, compared with standard HSG, was 94%, with a positive predictive value of 85%; specificity was 95%, with a negative predictive value of 98%. The Kappa coefficient was 0.85 (p < 0.001). CONCLUSION: Our results suggest that ultrasound may be used as a frontline imaging modality for patients after Essure microinsert placement.
