Impact of Crohn's disease on obstetrical management.

OBJECTIVE: Patients with Crohn's disease (CD) may have perineal lesions or a history of anorectal surgery that raise concerns about complications during delivery resulting in a discussion of cesarean section. Our objective was to study the impact of CD on the mode of delivery. METHOD: We conducted a retrospective study between 2005 and 2019 of the pregnancy outcomes of patients with CD. The primary endpoint was the performance of a cesarean section for a reason related to CD. RESULTS: Among 76 consecutive pregnancies, 19 patients underwent CD-related cesarean section (25%). The main element associated with scheduling a cesarean section was the existence of perineal involvement in 94.7% of cases, compared to 12.3% in the rest of the CD population (p<0.05). The perineal lesions most often involved were fistulas (47.4% versus 1.7%; p = 0.042). There was a history of perineal surgery in 78.9% of cases in the cesarean group vs 10,5% (p < 0.05) and a history of obstetric anal sphincter injury (OASI) in 10.5% of cases vs. 0 (p = 0.047). In women who gave birth vaginally, there were 17.9% episiotomy and one case of OASI (2.6%). CONCLUSION: The factors that influenced the choice of delivery route were perineal damage, history of perineal surgery and history of OASI.

Step-by-step development and evaluation of a 3D printed home-made low-cost pediatric tracheobronchial tree for foreign body aspiration extractions.

OBJECTIVES: The management of foreign body aspirations (FBA) is dreaded by pediatric physicians due to the high risk of respiratory distress and a potential fatal outcome, favored by a lack of experience of young specialists. Furthermore, there has been an increasing requirement for low-cost simulation. The aim was to describe the step-by-step manufacturing process and to validate a low-cost, easily home-made training model of pediatric tracheo-bronchial tree (pTBT) for simulation-based training in order to teach young physicians to practice foreign body (FBA) extractions. METHODS: A simulator was designed in order to reproduce the physical and esthetic properties of a pTBT. The production cost of a single simulator was estimated. The simulator was then tested by experienced physicians using a rigid bronchoscope. A manufacturing manual of the simulator is hereby presented. A group of 7 experienced pediatric otolaryngologists performed a FBA extraction in the conditions of installation of an operating room. RESULTS: The result of the survey showed a high fidelity of the simulator in mimicking the biological esthetics and physical properties of a pTBT during a FBA extraction (mean 4.3 ± 0.8). The total cost of the custom-made simulator is about 20.5 € ($23.4) for the production of the first simulator. CONCLUSIONS: A highly realistic and easily reproducible pediatric tracheo-bronchial tree simulator is presented and can therefore be used during simulation-based training.

Advanced Interventional Procedures after Intrauterine Tamponade Balloon Insertion in a Tertiary Care Center.

OBJECTIVE: To evaluate the rate of success and practicability of the intrauterine tamponade balloon (ITB) for managing PPH as a fertility-sparing tool. Methods: a five-year retrospective monocentric study in a tertiary care center including patients transferred for severe PPH. Results: In 231 patients, the success rate of ITB (n = 57), embolization (n = 58), and medical management (n = 114) was 84.21%, 74.13%, and 76.32%, respectively. Cesarean section during labor did not influence the risk of advanced interventional procedures (AIPs) for patients with ITB (odds ratio [OR] = 1.08) but did so in patients who were under expectant management in the intensive care (OR = 5.29). In the AIP subgroup of the ITB group, hemostasis was significantly deteriorated. Prothrombin time <50% (OR = 11.5), fibrinogen <2 g/L (OR = 6.88), and >4 red blood cells units (RBCs) transfused (OR = 17.2) were associated with a significantly higher risk of failure. Blood loss in the AIP patients in the embolization group was significantly higher. Patients requiring >4 units of RBCs were 22.9 times more likely to have an AIP (p = .0001). Conclusion: Compared with uterine embolization and medical management, ITB use in a tertiary care center was associated with lower risk of undergoing AIP, but further prospective study is required to confirm this.

Realization of Open Software Chain for 3D Modeling and Printing of Organs in Simulation Centers: Example of Renal Pelvis Reconstruction.

OBJECTIVE: Three-dimensional (3D) printing has many uses in healthcare such as in surgical training. It is becoming an interesting tool finding new pedagogical purposes in medical simulation. In this study, using a process consisting of 3D modeling, a simulator dedicated to pyeloplasty was designed, manufactured, and evaluated by experts. DESIGN: With the aid of open-source software and computer-aided design software, 3D models of a renal parenchyma, a renal pelvis and a ureter were created. This renal apparatus was processed and crafted with additive manufacturing using soft polymer materials. Polyvinyl alcohol material was used to print the components in order to make them dissectible and to evaluate their use in surgical teaching. SETTING AND PARTICIPANTS: Seven expert surgeons evaluated the model by performing a pyeloplasty sequence established in a previous work. An evaluation grid with 8 items related to surgical movement was rated on a 5-point Likert scale to assess how similar working with the model was to actual surgery. RESULTS: Three items were rated with a score greater than or equal to 4 (Needle penetration, Thread-sliding, and Cutting Strength). Suture strength was rated with a score above 3.5 for both renal pelvis and ureter, whereas elasticity was rated below 3. Handling and mobility properties were rated above 3 for the renal pelvis and below 3 for the ureter. The cost of the unit was $0.30 per renal unit. The primary difference identified was a difference in elongation between polyvinyl alcohol material and real biological tissue. CONCLUSIONS: It is feasible to generate and print a low cost upper urinary tract model from patient data imagery using environmentally friendly products that can be used effectively in surgical training. The simulator has been able to reproduce sensations related to surgical movements for a low cost. Hereafter, research into the pedagogical benefits provided to students, and through them, patients, should be performed. 3D printing models can offer new opportunities for healthcare simulation specific to different surgical fields.

Acid folic and pregnancy: A mandatory supplementation.

Neural tube defects (NTD) occur in 0.5 to 2 per 1000 pregnancies with various handicaps for the affected child. It is now well established that folic acid deficiency (absolute or relative) is a predisposing factor to this type of malformation. Several randomized controlled trials showed that high-dose folic acid (4mg) is an essential factor for prevention of neural tube defects recurrence and significantly prevents the first occurrence of neural tube defects with a lower dose (0.4mg). Other etiologies can favor the occurrence of NTD such as MTHFR polymorphism, some antiepileptic therapies, obesity and pregestational mellitus diabetes. Necessity of a preconception folic acid supplementation or at least folate nutritional status evaluation should be known for all of us including patients and public.

Pregnancy and vascular liver disease.

Vascular disorders of the liver frequently affect women of childbearing age. Pregnancy and the postpartum are prothrombotic states. Pregnancy seems to be a trigger for Budd-Chiari syndrome in patients with an underlying prothrombotic disorder. Whether pregnancy is a risk factor for other vascular liver disorders is unknown. In women with a known vascular liver disorder and a desire for pregnancy, stabilisation of the liver disease, including the use of a portal decompressive procedure when indicated, should be reached prior to conception. The presence of esophageal varices should be screened and adequate prophylaxis of bleeding applied in a manner similar to what is recommended for patients with cirrhosis. Most women likely benefit from anticoagulation during pregnancy and the postpartum. Labor and delivery are best managed by a multidisciplinary team with experience in this situation. Assisted vaginal delivery is the preferred mode of delivery. Although the risk of miscarriage and premature birth is heightened, current management of these diseases makes it very likely to see the birth of a live baby when pregnancy reaches 20 weeks of gestation.

Preconception care in France.

OBJECTIVE: Preconception care is advocated throughout the world as a tool for improving perinatal outcomes. However, the proportion of women in France who attend a dedicated medical preconception visit is unknown. METHODS: We undertook a retrospective study among 401 women who delivered at a maternity clinic or hospital in France to determine how many of them had attended a preconception visit. We also collected information on various preconception care behaviors such as folate supplementation and alcohol or tobacco cessation. RESULTS: In total, 21.6% of the women took a folate prescription, and 91.3% and 68.6% of women stopped alcohol and tobacco consumption, respectively. Of the 80.2% of women who visited a doctor within the 6 months before conception, only 13.8% discussed their planned pregnancy at this visit. CONCLUSION: Although the rate of vitamin supplementation remains low, there has been an increase in adequate preconception care behavior. This indicates that improvement is possible and should be implemented.

Uterine necrosis following pelvic arterial embolization for post-partum hemorrhage: review of the literature.

Uterine necrosis is one of the rarest complications following pelvic arterial embolization for postpartum hemorrhage (PPH). With the increasing incidence of cesarean section and abnormal placental localization (placenta previa) or placental invasion (placenta accreta/increta/percreta), more and more cases of uterine necrosis after embolization are being diagnosed and reported. Pelvic computed tomography or magnetic resonance imaging provides high diagnostic accuracy, and surgical management includes hysterectomy. We performed a Medline database query following the first description of uterine necrosis after pelvic embolization (between January 1985 and January 2013). Medical subheading search words were the following: "uterine necrosis"; "embolization"; "postpartum hemorrhage". Seventeen citations reporting at least one case of uterine necrosis after pelvic embolization for PPH were included, with a total of 19 cases. This literature review discusses the etiopathogenesis, clinical and therapeutic aspects of uterine necrosis following pelvic arterial embolization, and guidelines are detailed. The mean time interval between pelvic embolization and diagnosis of uterine necrosis was 21 days (range 9-730). The main symptoms of uterine necrosis were fever, abdominal pain, menorrhagia and leukorrhea. Surgical management included total hysterectomy (n=15, 78%) or subtotal hysterectomy (n=2, 10%) and partial cystectomy with excision of the necrotic portion in three cases of associated bladder necrosis (15%). Uterine necrosis was partial in four cases (21%). Regarding the pathophysiology, four factors may be involved in uterine necrosis: the size and nature of the embolizing agent, the presence of the anastomotic vascular system and the embolization technique itself with the use of free flow embolization.

Modulation of free corticotrophin-releasing hormone, adrenal and placental steroid hormone levels induced by mifepristone during pregnancy.

UNLABELLED: Mifepristone is a progesterone receptor antagonist widely used in obstetrics. The aim of the study was to focus on free corticotrophin-releasing hormone (CRH) and also describe modulation of adrenal and placental steroid hormone concentrations induced by mifepristone. METHODS: Twenty-six women were enrolled in the study. They received mifepristone for termination of pregnancy. Maternal blood samples were retrieved before administration of mifepristone (600 mg) and 48 h after, just before induction of labor. Bound and free CRH levels were determined in maternal blood concomitantly with cortisol, estriol, progesterone and SDHEA levels. Also paired fetal cord blood samples were collected. RESULTS: Maternal plasmatic CRH level did not change after mifepristone absorption but free CRH increased significantly (0.500 ± 0.326 vs. 0.388 ± 0.303 ng/ml, p = 0.040). A significant decrease of progesterone was observed (83.6 ± 49.3 vs. 95.6 ± 54.9 ng/ml, p = 0.001) with a lower progesterone/estriol ratio (26.9 ± 15.7 vs. 40.7 ± 31.1, p = 0.004). There was a strong association between maternal and fetal free CRH (r² = 0.675, p = 0.001), cortisol (r² = 0.570, p = 0.019), and positive but modest correlation for progesterone (r² = 0.341, p = 0.046) and estriol (r² = 0.379, p = 0.025) levels. CONCLUSION: Mifepristone has an effect on free CRH level and changes the estriol-progesterone balance.

Unusual synechia at hysterosalpingography: intrauterine fallopian tube after surgical abortion.

We report a patient who had uterine perforation with incarceration of the fallopian tube after surgical abortion. The diagnosis was made during hysteroscopy, realized after hysterosalpingography, and treated by laparoscopy.

Obstetrical and neonatal outcomes of pregnancies following gastric bypass surgery: a retrospective cohort study in a French referral centre.

BACKGROUND: The objective of this study was to analyze obstetrical and neonatal outcomes following Roux en Y Gastric Bypass procedures (RYGBP). METHODS: A retrospective cohort study was conducted in a single French tertiary perinatal care and bariatric center. The study involved 24 pregnancies, following RYGBP (exposed group) and two different control groups (non-exposed groups). A body mass index (BMI)-matched control group included 120 pregnancies matched for age, parity, and pregnancy BMI. A normal BMI control group included 120 pregnancies with normal BMI (18.5-24.9 kg/m(2)), matched for age and parity. Hospital data were reviewed from all groups in the same 6-year period. Obstetrical and neonatal outcomes after RYGB were compared, separately, to the two different-matched control groups. RESULTS: The median interval from RYGBP to conception was 26.6 (range: 3-74) months. Rates of perinatal complications did not differ significantly between the RYGBP group and normal BMI and BMI-matched controls groups. The rate of Cesarean section before labor was higher in the RYGBP patients than in the normal BMI control group (25% vs. 9.3% respectively, p = 0.04). Weight gain was lower in the RYGBP patients than normal BMI control group (5.8 kg vs. 13.2 kg respectively, p < 0.0001). Birthweight was also lower in the RYGBP group than those in normal BMI and BMI-matched controls groups (2,948.2 g vs. 3,368.2 g and 3,441.8 g, respectively, p < 0.0001). CONCLUSIONS: RYGBP surgery was associated with reduced birthweight, suggesting a possible role of nutritional growth restriction in pregnancy.

Pregnancy and delivery in patients with portal vein cavernoma.

BACKGROUND: Portal vein cavernoma (PVC) is a rare disease resulting from extrahepatic portal vein thrombosis and development of collateral venous circulation. The management of pregnancy and delivery in woman with PVC has rarely been described. CASES: Two primiparous women are presented to illustrate the management of PVC during pregnancy and discuss the delivery route according to the symptoms and the PVC complications. The first patient presented PVC associated with large jejunal varices and high anticardiolipid antibodies. She was treated with beta-blocker therapy and low molecular weight heparin during pregnancy, and delivered by cesarean section. The second patient presented protein S deficiency complicated by PVC and thrombocytopenia and delivered vaginally without complications. CONCLUSION: Many issues should be considered when counseling women with PVC, including the management before and during pregnancy according to symptoms and PVC complications. A multidisciplinary approach seems to be key to the management of delivery. Our advice to caregivers is that elective cesarean section seems necessary in cases with digestive varices. Vaginal delivery, with a passive second stage, seems to be relatively safe and less morbid in women without digestive varices, when maternal and fetal tolerance permits.

[Quality of life assessment after TVT (tension-free vaginal tape) based on 3 different questionnaires]. / Evaluation de la qualité de vie après TVT (tension-free vaginal tape) à l'aide de 3 questionnaires différents.

OBJECTIVE: To prospectively evaluate the effects of TVT on the quality of life of patients with urinary incontinence by using 3 different questionnaires. PATIENTS AND METHODS: Fifty one patients with a mean age of 57.1 years (range: 34 to 82) were treated by TVT for urinary incontinence combined with laparoscopic sacral colpopexy for associated cystocele in 12 cases. Fifty of these patients suffered from stress urinary incontinence and one presented mixed urinary incontinence. These patients completed 2 quality of life questionnaires and a urinary symptom score: Ditrovie and Contilife scale and the MHU scale for measurement of urinary handicap before and 3 months after TVT. Statistical analysis was based on Student's test. RESULTS: The mean scores obtained with the MHU scale were 6.74 (range: 2-16) preoperatively and 1.4 (range: 0-7) postoperatively. The mean score obtained with the Ditrovie scale was 3.1 (range: 2-4) preoperatively and 1.32 (range: 1-3) postoperatively. The mean score obtained with the Contilife scale was 82.1 (range: 51-119) preoperatively and 38.8 (range: 30-15) postoperatively. The difference was statistically significant (p<0.05) for the MHU and Contilife scales, but not for the Ditrovie scale. CONCLUSION: TVT allows a marked improvement of the quality of life of patients with urinary incontinence. The MHU and Contilife questionnaires can be used to objectively quantify the improvement of quality of life after TVT and, due to their marked and reproducible variation, they can also be used to assess the degree of improvement and the stability of the results over time.

[Pelvic pain caused by bladder leiomyoma: diagnostic and radiologic difficulties]. / Algies pelviennes d'un léiomyome de vessie: difficultés diagnostique et radiologique.

Uterine leiomyoma is a frequent benign lesion. It is usually asymptomatic and can be responsible for acquired dysmenorrhoea in some women, leading to gynaecological assessment. However, the development of this type of muscle lesions arising from the bladder wall and accompanied exclusively by dysmenorrhoea is rare. It is very difficult to study the anatomical relations of the lesion and distinguish it from other pelvic, genital or urinary tract tumours. The authors discuss the diagnostic aspects and therapeutic management in the light of a case of bladder leiomyoma in a 39-year-old woman.
