Accuracy of fetal fibronectin for the prediction of preterm birth in symptomatic twin pregnancies: a pilot study

Our goal was to evaluate the performance of fetal fibronectin (fFN) test alone or combined with cervical length (CL), to predict spontaneous preterm birth (PTB) in symptomatic twin pregnancies. We carry out a short pilot study including all uncomplicated diamniotic twin pregnancies with symptoms of preterm labor (PTL) and intact membranes at 24-33 weeks + 6 days of gestation. Studied outcome were spontaneous delivery within 7 and 14 days of testing and spontaneous PTB at <34 and <37 weeks of gestation. Among 40 women, fFN test was positive in 3 of them (7.5%). Regardless of the outcome studied CL did not significantly predict PTB. Performance of fFN was sensitivity (66.7%), specificity (97.2%), positive predictive value (66.7%), negative predictive value (97.2%), positive likelihood ratio (LR) (24.0), and negative LR (0.3) to predict spontaneous PTB within 7 days (p = 0.01). Thus, 66.1% of patients with a positive fFN test would deliver within 7 days versus 2.4% if negative testing; starting with a pre-test probability of 7.5%. Combining CL and fFN did not enable to increase enough positive LR or decrease significantly negative LR. In conclusion, fFN test alone might have a better ability to detect spontaneous delivery within 7 days among symptomatic twin pregnancies.

Ectopic pregnancy 6 years after subtotal hysterectomy: A case report

BACKGROUND

Only 57 cases of ectopic pregnancy after hysterectomy have been published.

CASE REPORT

A 34-year-old patient with a history of subtotal hysterectomy for postpartum hemorrhage consulted for acute abdominal pain. The diagnosis of ectopic pregnancy was made using blood pregnancy test and transvaginal ultrasound. Emergency laparoscopy was performed.

CONCLUSION

Urine pregnancy test should be performed in case of unexplained haemoperitoneum in patient of childbearing age with a history of hysterectomy. Fistulous tracts between the patent cervix or the vaginal cuff and the peritoneal cavity may allow fecundation. TEACHING POINTS: (1) Ectopic pregnancy remains a differential diagnosis of abdominal pain and haemoperitoneum in patient of childbearing age even after hysterectomy. (2) Fistulous tract between the residual cervix and the peritoneal cavity or tubes may allow fecundation.

MRI and Ultrasound Fusion Imaging for Cervical Cancer

BACKGROUND

Evaluating locoregional extension of cervical cancer is a key step in patient management. This study evaluated the feasibility of fusion imaging - a combination of magnetic resonance imaging (MRI) with real-time high-resolution ultrasound (US) - to diagnose cervical cancer and its extension.

PATIENTS AND METHODS

This prospective bi-center study included 13 women who underwent a 1.5-T MRI protocol including at least one T2-weighted plane. The results of imaging fusion were then compared with US and MRI results alone.

RESULTS

Cervical cancer was detected as a hyperechogenic hypervascularized lesion. Parametrial extension was detected by exploration of the stromal ring and the use of color Doppler mode in fusion imaging, and characterized by visualization of a vascular bridge.

CONCLUSION

Fusion imaging could be used as a complementary technique for MRI to enhance diagnostic performance for cervical cancer lesions. While MRI remains the reference, real-time fusion imaging could improve its characterization and detect parametrial infiltration.

Economic impact of ulipristal acetate on surgical procedures for uterine fibroids in France

OBJECTIVE

To assess the budget impact of using ulipristal acetate (UPA) 5 mg to treat women with uterine fibroids (UF) causing moderate to severe symptoms.

DESIGN

We modelled trends in the number of surgical procedures for symptomatic UF, with and without the use of UPA for preoperative or intermittent treatment and assessed the budget impact of UPA use from the French national healthcare insurance system perspective.

SETTING

A French national hospital database (PMSI) that records admissions and relative procedures to public and private hospitals.

PARTICIPANTS

Women eligible for surgical procedures for uterine fibroids.

MAIN OUTCOME MEASURES

Economic impact of UPA treatment.

RESULTS

This study based on observational retrospective data shows that the current use of UPA in its preoperative indication was associated with 5645 fewer surgeries from 2013 to 2015. Extrapolation suggests 17 885 fewer surgeries from 2016 to 2019. Overall, preoperative use of UPA results in substantial cost savings for the French national healthcare insurance system, with a cumulated budget impact estimated at €-5 million from 2013 to 2015 and €-13.5 million from 2016 to 2019. In addition, treating women nearing the menopause (≥48 years old) with intermittent treatment from 2017 to 2019 could produce an incremental cost saving of €19 million.

CONCLUSIONS

This study shows that the use of UPA in women eligible for surgical procedures for UF is associated with considerable savings for the French national healthcare insurance system in both preoperative and intermittent indications by decreasing the need to perform surgeries.

Reproducibility of the interpretation of coronal 3D ultrasound view of the uterus to evaluate the position of Essure® 3 months after hysteroscopic procedure

OBJECTIVE

Three-dimensional sonography is a good alternative method to assess the position of microinserts. Adequate position after three months allows for the interruption of other contraception. Objective is to evaluate inter-observer reproducibility of the interpretation of coronal transvaginal 3D ultrasound view of the uterus to evaluate the position of Essure^®.

STUDY DESIGN

Inter-observer reproducibility study. Fifty women underwent successful bilateral placement of microinserts (Essure^®) by hysteroscopy in the Department of Gynaecology of a teaching hospital and were included in the study. At three month, 3D ultrasound coronal views of the fifty uterus (accounting for one hundred microinserts) were assessed by five different observers and microinsert position was classified according to the classification described by Legendre et al. Inter-observer reproducibility in reading the 3D coronal view of the uterus was evaluated.

RESULTS

The k-value was disparate, from 0.26 to 0.82. Inter-observer reproducibility then ranged from fair to almost perfect, depending on a prior knowledge of the position classification.

CONCLUSIONS

Transvaginal 3D coronal view of the uterus is sufficient to assess the positioning of the microinserts when the practionner or the surgeon is familiar with the classification method.

Standardizing hysteroscopy teaching: development of a curriculum using the Delphi method

BACKGROUND

Hysteroscopy is performed often and in many indications but is challenging to learn. Hands-on training in live patients faces ethical, legal, and economic obstacles. Virtual reality simulation may hold promise as a hysteroscopy training tool. No validated curriculum specific in hysteroscopy exists. The aim of this study was to develop a hysteroscopy curriculum, using the Delphi method to identify skill requirements.

METHODS

Based on a literature review using the key words "curriculum," "simulation," and "hysteroscopy," we identified five technical and non-technical areas in which skills were required. Twenty hysteroscopy experts from different French hospital departments participated in Delphi rounds to select items in these five areas. The rounds were to be continued until 80-100% agreement was obtained for at least 60% of items. A curriculum was built based on the selected items and was evaluated in residents.

RESULTS

From November 2014 to April 2015, 18 of 20 invited experts participated in three Delphi rounds. Of the 51 items selected during the first round, only 25 (49%) had 80-100% agreement during the second round, and a third round was therefore conducted. During this last round, 80-100% agreement was achieved for 31 (61%) items, which were used to create the curriculum. All 14 residents tested felt that a simulator training session was acceptable and helped them to improve their skills.

CONCLUSIONS

We describe a simulation-based hysteroscopy curriculum focusing on skill requirements identified by a Delphi procedure. Its development allows standardization of training programs offered to residents.

Quality assessment of pelvic ultrasound for uterine myoma according to the CNGOF guidelines

INTRODUCTION

French guidelines regarding the minimum criteria for gynaecological ultrasound were given in a recent report in 2016, by the French National College of Obstetricians and Gynaecologists (CNGOF). An accurate report is essential for the optimal care of women, especially those presenting myomas. The goal of this study was to evaluate the quality of gynaecological ultrasound reports for women with type 0 to 2 uterine myomas, referring to the items contained in the French guidelines.

MATERIALS AND METHODS

A retrospective descriptive study was conducted from reports of ultrasounds performed in private offices and in the gynaecologic department of a hospital, between June 2014 and June 2016 (before the report of CNGOF). These reports involved women who underwent hysteroscopic resection of myoma(s). A search of validated items was conducted for all of the reports, and the missing items were analysed. The different types of practitioners and between hospital and private medical offices were also compared with Chi-square tests.

RESULTS

A total of 138 reports were analysed; 71 were performed in private offices and 67 were performed in the gynaecologic unit of the hospital. Many items were missing in the reports, with disparities between the type of institution (private offices or hospital) and the speciality of practitioners (radiologists or gynaecologists). Specific items regarding myomas, such as the International Federation of Gynaecologists and Obstetricians (FIGO) classification or measurement of the posterior wall, were more often missing in reports from radiologists (89.7% and 79.5%, respectively) than in reports from gynaecologists (21.2% and 34.3%, respectively) (P<0.05). A significant difference was also observed for these data between private offices' reports and hospitals' reports. Items relative to ultrasound structures, such as the appearance of myomas or associated abdominal effusion, were more frequently missing in gynaecologists' reports (88.9% and 49.5%, respectively) compared to radiologists' reports (56.4% and 12.8%, respectively) (P<0.05).

CONCLUSIONS

Certain items are present in all the reports, while others are insufficiently mentioned. These inequalities can be explained in part by the type of practice; however, methods to overcome these difficulties must be developed. Information campaigns to educate professionals on the minimum reporting and training conducted jointly by radiologists and gynaecologist surgeons might improve reports and improve the care of women.

[Interest of saline contrast sonohysterography for the diagnosis of cesarean scar defects]

OBJECTIVES

To determine the interest of saline contrast sonohysterography in the evaluation of number, size and shape of cesarean scar defects in comparison with 3D-transvaginal ultrasound examination.

METHODS

Patients who had surgical reparation of cesarean scar defect by operative hysteroscopy were included in this retrospective study. Before surgery, they all had 3D-transvaginal ultrasound examination and saline contrast sonohysterography to establish the diagnosis. Then those two exams were compared to determine which one is better for cesarean scar defect evaluation, in terms of diagnosis and severity.

RESULTS

Fourteen patients were enrolled, they underwent transvaginal ultrasound and saline contrast sonohysterography before the surgery. 3D-transvaginal ultrasound examination made the diagnosis in 50% of patients with cesarean scar defect, whereas saline contrast sonohysterography enabled to detect 86% of defects, in comparison with hysteroscopy (100%). In 29% of patients, the size and depth of the cesarean scar defect was more important with saline contrast sonohysterography and hysteroscopy than expected by 3D-transvaginal ultrasound examination. After surgical repair, symptoms improvement was found in 82% of case (pain or abnormal uterine bleeding), and fertility was restored in 67%.

CONCLUSION

Saline contrast sonohysterography is better to characterize cesarean scar defects than 3D-transvaginal ultrasound, with a higher sensibility. Moreover, it evaluates more precisely the size and shape of the defect, thus severity.

[Medical management of interstitiel pregnancy by in situ methotrexate]

INTRODUCTION

Interstitial pregnancy accounts for 3 to 11% of ectopic pregnancy; these pregnancies are the more frequently non-tubal ectopic pregnancy. Medical treatment can be used in case of unruptured interstitial pregnancy and is used more and more frequently to avoid hemorrhagic risk and risk of conversion to radical surgery when a surgical management is decided. However, a larger use of methotrexate in interstitial pregnancy and conditions of use are not clearly defined. The aim of this study is to report a series of unruptured interstitial pregnancy managed by in situ injection of methotrexate.

WOMEN AND METHODS

This retrospective observational study included women treated for an interstitial pregnancy between 2010 and 2013 in a teaching hospital. Medical management used was an in situ injection of methotrexate (1mg/kg) guided by vaginal sonography plus an intramuscular injection of methotrexate (1mg/kg) in the 48hours following in situ injection and 600mg of mifepristone when progesterone blood rate was more than 9ng/mL. A great decrease of serum hCG without surgery was considered a success.

RESULTS

Fourteen women had an interstitial pregnancy during the study period. Six were managed surgically in 5 cases for suspicion of uterine rupture and one for pregnancy of unknown location. Eight women had a medical management and the success rate was 100%. Mean time for decrease of serum hCG until 2 UI/L was 54.4 days [34.0-74.8]. No uterine rupture or immediate complication was reported. Five women out of 8 had a spontaneous pregnancy after management of interstitial pregnancy.

CONCLUSION

Medical management by in situ injection of methotrexate under sonographic guidance with an intramuscular injection within the 48hours following the in situ injection and mifepristone when ectopic pregnancy was active can be proposed in first-line therapy in case of unruptured interstitial pregnancy. This treatment has a great efficiency and low rate of complications.

Synchronous rectal adenocarcinoma and splenic marginal zone lymphoma

Synchronous cancers of different primary origin are rare. Here, we describe the case of a patient with concomitant diagnoses of rectal adenocarcinoma and splenic marginal zone lymphoma (smzl). A 57-year-old woman initially presented with abdominal pain. Physical examination and computed tomography demonstrated massive splenomegaly, and a complete blood count revealed microcytic anemia and lymphopenia. During the subsequent evaluation, she presented with hematochezia, melena, and constipation, which prompted gastroenterology referral. Subsequent endoscopic rectal ultrasonography revealed a T3N1 moderately differentiated rectal adenocarcinoma, with computed tomography imaging of chest, abdomen, and pelvis confirming no metastasis. Thus, the cancer was classified as clinical stage T3N1M0, stage iii. Bone marrow biopsy confirmed co-existing marginal zone lymphoma, and with the clinical presentation of massive splenomegaly, a diagnosis of smzl was made. The patient's management was individually tailored for simultaneous optimal treatment of both conditions. Concurrent treatment with neoadjuvant rituximab and 5-fluorouracil chemotherapy, with external-beam radiation therapy to the pelvis, was administered, followed by surgery consisting of en bloc splenectomy and distal pancreatectomy, and low anterior resection. The patient completed a standard course of adjuvant folfox (fluorouracil-leucovorin-oxaliplatin) chemotherapy and has remained disease-free for 7 years. To our knowledge, this report is the first to specifically describe simultaneous diagnoses of locally advanced rectal cancer and smzl. We also describe the successful combined neoadjuvant treatment combination of 5-fluorouracil, rituximab, and pelvic radiation.
