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

In vitro effect of hyoscine-N-butyl bromide and diclofenac sodium in human tuba uterina

INTRODUCTION

To investigate the in vitro effect of diclofenac on tubal smooth muscle as an alternative to hyoscine-N-butyl bromide, which is used for premedication before hysterosalpingography (HSG).

MATERIAL AND METHODS

Fallopian tubes were retrieved from seven healthy women after bilateral tubal ligation and in vitro contractility and histological studies were conducted using tissue bath and immunohistochemistry.

RESULTS

Diclofenac sodium and hyoscine-N-butyl bromide did not significantly change the basal mean tension; however, they decreased the contractions induced by potassium chloride (KCl). The relaxant effect of diclofenac sodium and hyoscine-N-butyl bromide was not statistically significantly different. The presence of cyclooxygenase (COX)-2 enzyme in the fallopian tube was demonstrated by immunohistochemical studies.

CONCLUSIONS

The in vitro relaxant effect of diclofenac sodium on the fallopian tube is similar to hyoscine-N-butyl bromide. Diclofenac may have the potential to be used as an alternative to hyoscine-N-butyl bromide in premedication in HSG.

Fertility Outcome and Safety of Ethiodized Poppy Seed Oil for Hysterosalpingography in 1,053 Infertile Patients: A Real-World Study

Objective

Ethiodized poppy seed oil for hysterosalpingography (HSG) is reported to display some therapeutic effect on infertility, but big a sample-size study under real clinical settings is still lacking to verify the speculation. Thus, this real-world study enrolled 1,053 infertile patients who underwent ethiodized poppy seed oil-based HSG to explore its fertility enhancement value.

Method

A total of 1,053 infertile patients who underwent HSG using ethiodized poppy seed oil as the contrast medium were retrospectively analyzed. The live birth rate and 3-, 6-, 12-month and total pregnancy rate were retrieved. Besides, adverse events during and after HSG were recorded.

Results

The 3-, 6-, 12-month and total pregnancy rate was 22, 36.8, 50, and 53.8%, respectively. The total live birth rate was 42.7%. Sub-group analyses showed that pregnancy rate was 53.7, 53.8, 54.1, and 62.4% in subgroups of primary infertility patients, secondary infertility patients, infertility patients with fallopian tube disease, and infertility patients with unknown cause, respectively. Meanwhile the live birth rate was 44.3, 41.3, 41.5, and 59.2% in these subgroups, separately. Multivariate logistic regression analysis disclosed that BMI ≥ 24 kg/m², history of dysmenorrhea, and abnormity of sperm count or motility-related infertility were independently correlated with reduced pregnancy rate and livebirth rate (All Ps < 0.05). Adverse events mainly included pain (20.6%) and interstitial reflux (7.9%), which were mild and tolerable.

Conclusion

Ethiodized poppy seed oil for HSG discloses a satisfying fertility outcome with a tolerable safety profile in infertile patients; meanwhile, this effect might be influenced by BMI, history of dysmenorrhea, and paternal abnormity of sperm.

Ethiodized poppyseed oil-based contrast medium is superior to water-based contrast medium during hysterosalpingography regarding image quality improvement and fertility enhancement: A multicentric, randomized and controlled trial

BACKGROUND

The efficacy of ethiodized poppyseed oil in hysterosalpingography (HSG) image quality and fertility enhancement has been revealed, but whether this HSG modality has similar effects in the Chinese population is still unclear.

METHODS

Between July 18, 2017, and December 29, 2019, this multicentric, randomized, two-arm, clinical trial was performed involving 15 medical centers. Infertile women meeting HSG indications were randomly assigned to an oil group and a water group. The coprimary outcome included HSG image quality during HSG and fertility-enhancing effects of HSG. This study was registered on ClinicalTrials.gov (NCT03370575).

FINDINGS

A total of 1026 subjects were randomly assigned to an oil group (N = 508) and a water group (N = 518). HSG image quality revealed that the oil group had outstanding visualization (all P < 0.001); total image quality scores for uterus opacification or uterine outline (2.9 ± 0.4 vs. 2.7 ± 0.5), fallopian tube outline (2.3 ± 0.8 vs. 1.7 ± 0.7), fimbrial rugae (1.7 ± 1.0 vs. 1.3 ± 0.8), fallopian tube spillage (2.1 ± 0.9 vs. 1.6 ± 0.8), peritoneal distribution (2.6 ± 0.9 vs. 2.1 ± 1.0) and diagnostic quality (11.6 ± 3.4 vs. 9.5 ± 3.1) (all P < 0.001) were higher in the oil group than in the water group. Regarding fertility-enhancing evaluation, the oil group showed an increased cumulative on-going pregnancy rate, on-going pregnancy within 6 months (29.1% vs. 20.1%), clinical pregnancy (39.5% vs. 29.1%) and live birth ≥ 24 weeks of gestation (36.1% vs. 27.7%) but a shorter time to pregnancy than the water group (all P < 0.01). Concerning adverse events, the oil group showed a lower occurrence rate of abdominal pain and vaginal bleeding after HSG (both P < 0.01).

INTERPRETATION

Ethiodized poppyseed oil-based contrast is superior to water-based contrast during HSG in terms of image quality improvement and fertility enhancement. This study indicates the priority of the application of ethiodized poppyseed oil-based contrast during the HSG procedure in infertile patients.

The effect of hyoscine-N-butylbromide on pain perception during and after hysterosalpingography in infertile women: a systematic review and meta-analysis of randomised controlled trials

This paper reports a systematic review and meta-analysis of the effectiveness of hyoscine-N-butylbromide (HBB) administration in hysterosalpingography (HSG). Four electronic databases were searched for randomised controlled trials (RCTs) that compared HBB versus placebo or no intervention in infertile women undergoing HSG. Pain during and after HSG and different adverse events including nausea, vomiting, and dizziness were evaluated. Three RCTs with 335 patients were included. The analysis showed HBB was significantly effective in reducing pain during and after HSG (MD = -0.76 mm, 95% CI [-1.35, -0.17], p = 0.01) and (MD = -0.81 mm, 95% CI [-1.07, -0.56], p < 0.001), respectively. There were no significant differences in adverse events between HBB and control groups. The methodological evidence quality was high as evaluated by GRADEpro. In conclusion, this review provides good evidence that prior administration of HBB is effective in reducing induced pain during and after HSG with tolerable side effects.

Hysterosalpingographic findings in primary and secondary infertility patients

Objectives:

To highlight and compare spectrum of hysterosalpingography (HSG) findings in primary and secondary infertility patients.

Methods:

This retrospective record-based cross-sectional study was performed in the Radiology Department, King Fahad Military Medical City, Dhahran, Kingdom of Saudi Arabia between August 2016 and 2018. All patients (N=303) who underwent successful HSGs were included, and grouped under primary and secondary infertility cases. Patients with failed, limited or incomplete studies were excluded. Imaging findings were documented as N (Normal) or Ab (Abnormal). Abnormal HSG findings were further categorized as: C=congenital malformation, I=infection or inflammation, S=surgery, T=tumor or tear. Abnormal findings were confirmed on further imaging or intervention. Chi-square test was used to determine any association of HSG findings with type of infertility, and p-value less than 0.05 was considered significant.

Results:

Of the 303 patients, 166 patients (54.8%) had primary infertility while the rest had secondary infertility. Abnormal studies were found in less than one-third of patients (n=93, 30.7%). Primary infertility patients exhibited more congenital (C) malformations, while surgery (S) was seen more in secondary infertility patients (p=0.01).

Conclusion:

Congenital malformations are commonly found abnormalities on HSGs in primary infertility patients, while surgery related findings are seen in secondary infertility cases.
