RESUMEN

BACKGROUND: Placenta accreta spectrum is a life-threatening condition that has increased dramatically in recent decades along with cesarean rates worldwide. Cesarean hysterectomy is widely practiced in women with placenta accreta spectrum; however, the maternal outcomes after cesarean hysterectomy have not been thoroughly compared with the maternal outcomes after alternative approaches, such as conservative management. OBJECTIVE: This study aimed to compare the severe maternal outcomes between women with placenta accreta spectrum treated with cesarean hysterectomy and those treated with conservative management (leaving the placenta in situ). STUDY DESIGN: From a source population of 520,114 deliveries in 176 hospitals (PACCRETA study), we designed an observational cohort of women with placenta accreta spectrum who had either a cesarean hysterectomy or a conservative management (the placenta left in situ) during cesarean delivery. Clinicians prospectively identified women meeting the inclusion criteria and included them at delivery. Data collection started only after the women had received information and agreed to participate in the study in the immediate postpartum period. The primary outcome was the transfusion of >4 units of packed red blood cells within 6 months after delivery. Secondary outcomes were other maternal complications within 6 months. We used propensity score weighting to account for potential indication bias. RESULTS: Here, 86 women had conservative management and 62 women had cesarean hysterectomy for placenta accreta spectrum during cesarean delivery. The primary outcome occurred in 14 of 86 women in the conservative management group (16.3%) and 36 of 61 (59.0%) in the cesarean hysterectomy group (risk ratio in propensity score weighted model, 0.29; 95% confidence interval, 0.19-0.45). The rates of hysterectomy, total estimated blood loss exceeding 3000 mL, any blood product transfusion, adjacent organ injury, and nonpostpartum hemorrhage-related severe maternal morbidity were lower with conservative management than with cesarean hysterectomy (all adjusted, P≤.02); but, the rates of arterial embolization, endometritis, and readmission within 6 months of discharge were higher with conservative management than with cesarean hysterectomy. CONCLUSION: Among women with placenta accreta spectrum who underwent cesarean delivery, conservative management was associated with a lower risk of transfusion of >4 units of packed red blood cells within 6 months than cesarean hysterectomy.

RESUMEN

BACKGROUND: Quality care during childbirth requires that health care providers have not only excellent skills but also appropriate and considerate attitudes and behavior. Few studies have examined the proportion of women in Western countries expressing dissatisfaction with such inappropriate or inconsiderate behavior. This study evaluated this proportion in a sample presumably representative of French maternity units. METHODS: This prospective multicenter study, using data from a selfadministered questionnaire, took place in 25 French maternity units during one week in September 2018. The primary outcome measure was mothers' self-reported dissatisfaction with blatantly inappropriate behavior (ie, inappropriate attitude, inadequate respect for privacy, insufficient gentleness of care, and/or inappropriate language) by health care workers in the delivery room. The secondary outcome was their self-reported dissatisfaction with these workers' inconsiderate behavior (ie, unclear and inappropriate information, insufficient participation in decision-making, or deficient consideration of pain). RESULTS: Of 803 potentially eligible women, 627 completed the questionnaire after childbirth; 5.62% (35/623, 95% CI: 3.94-7.73) reported dissatisfaction with blatantly inappropriate behaviors and 9.79% (61/623, 95% CI: 7.57-12.40) with inconsiderate behaviors. The main causes of dissatisfaction reported by women in this survey were the inadequate consideration of their pain and the failure to share decision-making. CONCLUSIONS: Most of the women were satisfied with how health care workers behaved towards them in the delivery room. Nonetheless, health care staff must be aware of women's demands for greater consideration of their expressions of pain and of their voice in decisions.

RESUMEN

AIM: Identify women at risk of severe post-partum hemorrhage (PPH) by building a prediction model based on clinical variables available at PPH diagnosis. METHODS: We analyzed data on a cohort of 7236 women with PPH after vaginal delivery from 106 maternity units. Severe PPH was defined as the loss of more than 2000 mL of blood, peripartum drop in hemoglobin of 4 g/dL or more, transfusion of at least four packed red blood cells, embolization, hemostasis surgery, transfer to an intensive care unit or death. The Akaike criterion helped selecting the covariates of a multivariate logistic regression model. The performance of the model was studied through building a receiver-operator curve (ROC). The relative utility of the final model was used to determine the importance of the model in decision-making. RESULTS: Among all PPH, the prevalence of severe cases was 18.5%. Several clinical variables were significantly associated with severe PPH (e.g. parity, multiple pregnancy, labor induction, instrumental delivery). The multivariate prediction model was built. The area under the ROC for prediction of severe cases was 0.63 (95% confidence interval, 0.62-0.65). Nevertheless, the sensitivity and specificity of the prediction model were 0.49 and 0.70, respectively, for a threshold at 0.20 (near prevalence). The relative utility was 0.19 for a threshold near prevalence (20%). CONCLUSION: Because of important misclassifications, even the best model we could build with the available clinical data cannot be reasonably recommended for routine use. Every patient with PPH should receive most optimal management. Other types of information, possibly laboratory data, are probably needed.

RESUMEN

The medical team of the Croix Rousse teaching hospital maternity unit has developed, over the last ten years, a set of procedures designed to respond to various emergency situations necessitating Caesarean section. Using the Lucas classification, we have defined as precisely as possible the degree of urgency of Caesarian sections. We have established specific protocols for the implementation of urgent and very urgent Caesarean section and have chosen a simple means to convey the degree of urgency to all team members, namely a color code system (red, orange and green). We have set time goals from decision to delivery: 15 minutes for the red code and 30 minutes for the orange code. The results seem very positive: The frequency of urgent and very urgent Caesareans has fallen over time, from 6.1 % to 1.6% in 2013. The average time from decision to delivery is 11 minutes for code red Caesareans and 21 minutes for code orange Caesareans. These time goals are now achieved in 95% of cases. Organizational and anesthetic difficulties are the main causes of delays. The indications for red and orange code Caesarians are appropriate more than two times out of three. Perinatal outcomes are generally favorable, code red Caesarians being life-saving in 15% of cases. No increase in maternal complications has been observed. In sum: Each obstetric department should have its own protocols for handling urgent and very urgent Caesarean sections. Continuous monitoring of their implementation, relevance and results should be conducted Management of extreme urgency must be integrated into the management of patients with identified risks (scarred uterus and twin pregnancies for example), and also in structures without medical facilities (birthing centers). Obstetric teams must keep in mind that implementation of these protocols in no way dispenses with close monitoring of labour.

RESUMEN

This study aimed to explore the perception of an underutilised collaborative information system through qualitative research, utilizing semi-structured, in-depth interviews with independent midwives and physician. PROSPERO, is a collaborative information system designed to bridge the communication gap between community-based healthcare workers and hospital-based care teams for parturients in Lyon, France. Through 27 semi-structured in-depth interviews with midwives, obstetricians, and general practitioners, we identified key themes related to the system's adoption: implementation challenges, utilisation barriers, interprofessional dynamics, and hidden variables affecting system use. Participants recognised the potential of PROSPERO to improve information sharing and care coordination but expressed concerns about the system's integration into existing workflows, time constraints, and the need for adequate training and technical support. Interprofessional dynamics revealed differing perspectives between hospital and independent practitioners, emphasising the importance of trust-building and professional recognition. Hidden variables, such as hierarchical influences and confidentiality concerns, further complicated the system's adoption. Despite the consensus on the benefits of a collaborative information system, its implementation was hindered by mistrust between healthcare workers (i.e. between independent practitioners and hospital staff). Our findings suggest that fostering trust and addressing the identified barriers are crucial steps towards successful system implementation. The study contributes to understanding the complex interplay of factors influencing the adoption of collaborative healthcare technologies and highlights the need for strategies that support effective interprofessional collaboration and communication.ClinicalTrials ID NCT02593292.

RESUMEN

This study aimed to identify the risk factors for placenta accreta spectrum (PAS) in women who had at least one previous cesarean delivery and a placenta previa or low-lying. The PACCRETA prospective population-based study took place in 12 regional perinatal networks from 2013 through 2015. All women with one or more prior cesareans and a placenta previa or low lying were included. Placenta accreta spectrum (PAS) was diagnosed at delivery according to standardized clinical and histological criteria. Of the 520,114 deliveries, 396 fulfilled inclusion criteria; 108 were classified with PAS at delivery. Combining the number of prior cesareans and the placental location yielded a rate ranging from 5% for one prior cesarean combined with a posterior low-lying placenta to 63% for three or more prior cesareans combined with placenta previa. The factors independently associated with PAS disorders were BMI ≥ 30, previous uterine surgery, previous postpartum hemorrhage, a higher number of prior cesareans, and a placenta previa. Finally, in this high-risk population, the rate of PAS disorders varies greatly, not only with the number of prior cesareans but also with the exact placental location and some of the women's individual characteristics. Risk stratification is thus possible in this population.

RESUMEN

OBJECTIVE: To describe transfusion practices and anemia in women with postpartum hemorrhage (PPH), according to the clinical context. DESIGN: Population-based cohort study. SETTING: A total of 106 French maternity units (146 781 deliveries, December 2004 to November 2006). POPULATION: All women with PPH (n = 9365). METHODS: Description of the rate of red blood cell (RBC) transfusion in PPH overall and compared with transfusion guidelines. MAIN OUTCOME MEASURES: Transfusion practices and postpartum anemia by mode of delivery and cause of PPH in women given RBCs within 12 h after PPH. RESULTS: A total of 701 women received RBCs (0.48 ± 0.04% of all women and 7.5 ± 0.5% of women with PPH). Half the women with clinical PPH and hemoglobin lower than 7.0 g/dL received no RBCs. In the group with clinical PPH and transfusion within 12 h (n = 426), operative vaginal delivery was associated with a larger maximal hemoglobin drop, more frequent administration of fresh-frozen plasma (FFP) and pro-hemostatic agents [odds ratio (OR) 3.54, 95% confidence interval (95% CI) 1.12-11.18], transfusion of larger volumes of RBCs and FFP, a higher rate of massive RBCs transfusion (OR 5.22, 95% CI 2.12-12.82), and more frequent use of conservative surgery (OR 3.2, 95% CI 1.34-7.76), compared with spontaneous vaginal delivery. CONCLUSIONS: The RBC transfusion for PPH was not given in a large proportion of women with very low hemoglobin levels despite guidelines to the contrary. Operative vaginal delivery is characterized by higher blood loss and more transfusions than spontaneous vaginal delivery.

RESUMEN

OBJECTIVE: Reducing the rate of severe postpartum haemorrhage (PPH) is a major challenge in obstetrics today. One potentially effective tool for improving the quality of care is the clinical audit, that is, peer evaluation and comparison of actual practices against explicit criteria. Our objective was to assess the impact of regular criteria-based audits on the prevalence of severe PPH. DESIGN: Quasi-experimental before-and-after survey. SETTING: Two French maternity units in the Rhône-Alpes region, with different organization of care. PARTICIPANTS: All staff of both units. INTERVENTION: Quarterly clinical audit meetings at which a team of reviewers analysed all cases of severe PPH and provided feedback on quality of care and where all staff actively participated. MAIN OUTCOME MEASURES: The primary outcome was the prevalence of severe PPH. Secondary outcomes included the global quality of care for women with severe PPH, including the performance rate for each recommended procedure. Differences in these variables between 2005 and 2008 were tested. RESULTS: The prevalence of severe PPH declined significantly in both units, from 1.52 to 0.96% of deliveries in the level III hospital (P = 0.048) and from 2.08 to 0.57% in the level II hospital (P < 0.001). From 2005 to 2008, the proportion of deliveries with severe PPH that was managed consistently with the guidelines increased for all of its main components, in both units. CONCLUSION: Regular clinical audits of cases severe PPH were associated with a persistent reduction in the prevalence of severe PPH.

RESUMEN

OBJECTIVE: Assess the impact of implementation by simple distribution of a "colour code" protocol for emergency caesareans on the course over time of the "decision-delivery interval" (DDI) and neonatal outcome. DESIGN: Observational study in 26 maternity units of the AURORE perinatal network, conducted between October 1, 2017, and April 30, 2018. Each maternity ward́ was supposed to prospectively include 20 consecutive cases of caesareans performed either as an emergency, that is, as a code orange, or an extreme emergency, that is, code red. We compared the DDIs observed in 2017 to those in 2007 according to the degree of emergency, the maternity unit level of care, and their adherence to the protocol. Neonatal outcome in 2007 and 2017, assessed from laboratory and clinical indicators, was also compared, overall and according to the degree of emergency. RESULTS: The DDI was significantly lower in 2017 (n = 478) than in 2007 (n = 447), regardless of the degree of emergency and the level of care (p < 0.0001). In 2017, all code red caesareans were performed in less than 15 min in level 3 maternity units compared with 73 % (p = 0.039) in 2007. Fewer than 20 % of the caesareans in the 2007 study period were performed in less than 15 min in level 1 and 2 maternity units. Today, this is the case for 83 % of these caesareans in level 2 units (p < 0.001) and 36 % in level 1 (p = 0.01). In 2017, code orange caesareans were performed in less than 30 min in 96 % of cases in level 3 units, 67 % in level 2, and 33 % in level 1, compared respectively with 67 % (p = 0.015), 25 % (p < 0.0001) and 16 % (p = 0.0003) in 2007. We did not observe any difference in the neonatal outcome between 2007 and 2017 or as a function of the DDI expected based on the caesarean colour code. CONCLUSION: The implementation of the colour code protocols was associated with an improved DDI and better adherence to the recommendations in all 26 maternity units in this perinatal network.

RESUMEN

Patients with thrombophilia and/or a history of venous thromboembolism (VTE) exhibit a high risk of thrombosis during pregnancy. The present multicentre study prospectively assessed a prophylaxis strategy, based on a risk score, in pregnancies with increased risk of VTE. Among 286 patients included in the study, 183 had a personal history of VTE (63.98%) and 191 patients (66.8%) had a thrombophilia marker. Eighty nine (46.6%) thrombophilic women had a personal history of VTE. Patients were assigned to one of three prophylaxis strategies according to the risk scoring system. In postpartum, all patients received low molecular weight heparin (LMWH) prophylaxis for at least 6 weeks. In antepartum, LMWH prophylaxis was prescribed to 61.8% of patients with high risk of VTE. Among them, 37.7% were treated in the third trimester only and 24.1% were treated throughout pregnancy. In this cohort, one antepartum-related VTE (0.35%) and two postpartum-related VTE (0.7%) occurred. No case of pulmonary embolism was observed during the study period. The rate of serious bleeding was 0.35%. There was no evidence of heparin-induced thrombocytopenia or osteoporosis. The use of a risk score may provide a rational decision process to implement safe and effective antepartum thromboprophylaxis in pregnant women at high risk of VTE.

RESUMEN

We analysed changes in coagulation during normal pregnancy with a novel point-of-care device based on thrombelastometry (ROTEM). We compared the results obtained with those of standard coagulation tests in 104 patients: 20 non-pregnant women (controls) and 84 women in the first (T1, n = 17), second (T2, n = 9) and third (T3, n = 58) trimesters of pregnancy. We measured the clotting time (CT), the maximum clot firmness (MCF), the early clot amplitude at 5 and 15 minutes (CA(5), CA(15)) and the clot lysis index (CLI(30)) with four tests containing specific reagents. (a) The INTEM test involving ellagic acid activated the intrinsic pathway and (b) the EXTEM test using tissue factor triggered the extrinsic pathway; (c) The FIBTEM test based on a platelet inhibitor (cytochalasin D) evaluated the contribution of fibrinogen to clot formation and (d) the APTEM test was similar to the EXTEM but was based on inhibition in vitro of fibrinolysis by aprotinin. CT and CLI(30) were not significantly modified during pregnancy whereas MCF, CA(5) and CA(15) (INTEM, EXTEM, FIBTEM) increased significantly between the second and third trimesters (e.g. median [interquartile range]: MCF-FIBTEM, 13 [11-16] mm vs. 19 [17-23] mm, respectively, in controls and T3, p < 0.001). EXTEM values were not significantly different from those measured with APTEM. There were significant correlations between the results obtained with ROTEM and those from standard coagulation tests. ROTEM analysis showed a marked increase in coagulability during normal pregnancy. ROTEM values may serve as the basis for future studies in pregnant women.

RESUMEN

We sought to identify prenatal predictive factors for perinatal outcome and to estimate fetal hemoglobin (Hb) levels in large fetomaternal hemorrhages (transfused blood volume [TBV] > 20 mL) by performing a case-series study ( N = 32). Perinatal outcome was favorable (F group, N = 22) and poor (P group, N = 10: four fetal deaths, three postnatal deaths, three cases of severe anemia). Median TBV was 25 mL for the F group and 325 mL for the P group ( P < 0.0001) and median Hb concentration at birth was 15 g/dL for the F group and 5 g/dL for the P group ( P < 0.0001). Receiver operating characteristic analysis revealed that a Kleihauer-Betke test value above 2.5% was the best threshold for predicting adverse outcome, with sensitivity of 100% (95% confidence interval [CI] 76 to 100) and specificity of 96% (95% CI 77 to 100). In utero estimated Hb concentration best correlated with Hb level at birth when calculated using TBV corrected for fetoplacental weight ( P < 0.0001, R(2) = 0.874). The value obtained in the Kleihauer-Betke test was a prognostic factor, and TBV corrected for fetoplacental weight was the best biological marker for assessing fetal Hb level.

RESUMEN

Neural tube defects (NTDs) are severe congenital malformations due to failure of neural tube formation in early pregnancy. The proof that folic acid prevents NTDs raises the question of whether other parts of homocysteine (Hcy) metabolism may affect rates of NTDs. This French case-control study covered: 77 women aged 17-42 years sampled prior to elective abortion for a severe NTDs (cases) and 61 women aged 20-43 years with a normal pregnancy. Plasma and erythrocyte folate, plasma B6, B12 and Hcy were tested as five polymorphisms MTHFR 677 C --> T, MTHFR 1298 A --> C, MTR 2756 A --> G, MTTR 66 A --> G and TCN2 776 C --> G. Cases had significantly lower erythrocyte folate, plasma folate, B12 and B6 concentrations than the controls, and higher Hcy concentration. The odds ratio was 2.15 (95% CI: 1.00-4.59) for women with the MTRR 66 A --> G allele and it was decreased for mothers carrying the MTHFR 1298 A --> C allele. In multivariate analysis, only the erythrocyte folate concentration (P = 0.005) and plasma B6 concentration (P = 0.020) were predictors. Red cell folate is the main determinant of NTDs in France. Folic acid supplement or flour fortification would prevent most cases. Increased consumption of vitamins B12 and B6 could contribute to the prevention of NTDs. Genetic polymorphisms played only a small role. Until folic acid fortification becomes mandatory, all women of reproductive age should consume folic acid in a multivitamin that also contains B12 and B6.

RESUMEN

OBJECTIVE: To evaluate the effect of a novel communication tool, related to the degree of urgency for Caesarean sections (CSs), on the decision-to-delivery interval for emergency CS. STUDY DESIGN: Red CS are very urgent cases corresponding to life-threatening maternal or foetal situations, orange CS are urgent cases and green CS are non-urgent intrapartum CS. We carried out this cohort study in a French maternity hospital. The study included all emergency Caesarean sections during two 6-month periods, before and after introduction of the code. We compared the decision-to-delivery interval of the two study periods. RESULTS: Our study included 174 emergency CS. The mean decision-to-delivery interval after introduction of the code was 31.7 min, significantly shorter (p=0.02) than the 39.6 min interval before introduction of the colour code. Except for the preparation time, each time interval decreased. This included transporting the patient into the operating theatre, and the incision-to-delivery time interval. CONCLUSION: This study suggests that the use of the three-colour code could significantly shorten the decision-to-delivery interval in emergency CS. Further prospective studies are needed to confirm this result.

RESUMEN

Agnathia is a very rare malformation characterized by the absence of the mandible, which occurs either as an isolated malformation or in association with other deformities. We report the first case of an isolated agnathia diagnosed at 12 weeks due to the absence of the chin; the case was diagnosed using two- and three-dimensional ultrasonography and was confirmed by pathological analysis after the pregnancy was medically terminated at 17 weeks. Usually, isolated agnathia is a lethal malformation and its prenatal diagnosis is often delayed beyond the second trimester of pregnancy. We therefore suggest a systematic 'look at the CHIN', i.e. Chin, Headbone outlines (skull and nasal bones), Inner head, Nuchal translucency, using the sagittal view of the cephalic pole at 12 weeks.

RESUMEN

OBJECTIVE: Suboptimal care contributes to perinatal morbidity and mortality. We investigated the effects of a multifaceted program designed to improve obstetric practices and outcomes. STUDY DESIGN: A cluster-randomized trial was conducted from October 2008 to November 2010 in 95 French maternity units randomized either to receive an information intervention about published guidelines or left to apply them freely. The intervention combined an outreach visit with a morbidity/mortality conference (MMC) to review perinatal morbidity/mortality cases. Within the intervention group, the units were randomized to have MMCs with or without clinical psychologists. The primary outcome was the rate of suboptimal care among perinatal morbidity/mortality cases. The secondary outcomes included the rate of suboptimal care among cases of morbidity, the rate of suboptimal care among cases of mortality, the rate of avoidable morbidity and/or mortality cases, and the incidence of, morbidity and/or mortality. A mixed logistic regression model with random intercept was used to quantify the effect of the intervention on the main outcome. RESULTS: The study reviewed 2459 cases of morbidity or mortality among 165,353 births. The rate of suboptimal care among morbidity plus mortality cases was not significantly lower in the intervention than in the control group (8.1% vs. 10.6%, OR [95% CI]: 0.75 [0.50-1.12], p=0.15. However, the cases of suboptimal care among morbidity cases were significantly lower in the intervention group (7.6% vs. 11.5%, 0.62 [0.40-0.94], p=0.02); the incidence of perinatal morbidity was also lower (7.0 vs. 8.1‰, p=0.01). No differences were found between psychologist-backed and the other units. CONCLUSIONS: The intervention reduced the rate of suboptimal care mainly in morbidity cases and the incidence of morbidity but did not succeed in improving morbidity plus mortality combined. More clear-cut results regarding mortality require a longer study period and the inclusion of structures that intervene before and after the delivery room. (ClinicalTrials.gov ID: NCT02584166).

RESUMEN

OBJECTIVE: To evaluate the association between the planned mode of delivery and neonatal mortality and morbidity in an unselected population of women with twin pregnancies. METHODS: The JUmeaux MODe d'Accouchement (JUMODA) study was a national prospective population-based cohort study. All women with twin pregnancies and their neonates born at or after 32 weeks of gestation with a cephalic first twin were recruited in 176 maternity units in France from February 2014 to March 2015. The primary outcome was a composite of intrapartum mortality and neonatal mortality and morbidity. Comparisons were performed according to the planned mode of delivery, planned cesarean or planned vaginal delivery. The primary analysis to control for potential indication bias used propensity score matching. Subgroup analyses were conducted, one according to gestational age at delivery and one after exclusion of high-risk pregnancies. RESULTS: Among 5,915 women enrolled in the study, 1,454 (24.6%) had planned cesarean and 4,461 (75.4%) planned vaginal deliveries, of whom 3,583 (80.3%) delivered both twins vaginally. In the overall population, composite neonatal mortality and morbidity was increased in the planned cesarean compared with the planned vaginal delivery group (5.2% compared with 2.2%; odds ratio [OR] 2.38, 95% confidence interval [CI] 1.86-3.05). After matching, neonates born after planned cesarean compared with planned vaginal delivery had higher composite neonatal mortality and morbidity rates (5.3% compared with 3.0%; OR 1.85, 95% confidence interval 1.29-2.67). Differences in composite mortality and morbidity rates applied to neonates born before but not after 37 weeks of gestation. Multivariate and subgroup analyses after exclusion of high-risk pregnancies found similar trends. CONCLUSION: Planned vaginal delivery for twin pregnancies with a cephalic first twin at or after 32 weeks of gestation was associated with low composite neonatal mortality and morbidity. Moreover, planned cesarean compared with planned vaginal delivery before 37 weeks of gestation might be associated with increased composite neonatal mortality and morbidity.

RESUMEN

OBJECTIVE: The purpose of this study was to create a new instrument for the training of doctors in the use of forceps and to compare the trajectories of forceps blades between junior and senior obstetricians. STUDY DESIGN: We equipped a simulator and forceps with spatial location sensors. The head of the fetus was in an occipitoanterior location, at a "+5" station. Forceps blade trajectories were analyzed subjectively with the 3-dimensional spatial graph and objectively based on 3 points of special interest. Each obstetrician performed 4 forceps blades placements. We compared the trajectories of junior and senior obstetricians. RESULTS: For senior operators, spatial dispersion was "excellent," "very good," or "good" in 92% of cases, whereas this was the case for only 38% of junior doctors (92% vs 38%; P < .001). CONCLUSION: A new instrument has been designed to demonstrate the trajectory of forceps blades during application in a simulator. The instrument captures the difference in experience between senior and junior clinicians.

RESUMEN

OBJECTIVES: Deep infiltrating endometriosis (DIE) raises a number of diagnostic and therapeutic problems. Magnetic resonance imaging (MRI), the reference technique in endometriosis, is questioned for posterior pelvic lesions, especially in rectosigmoid locations. In this study, we describe a new technique called three-dimensional rectosonography (3D-RSG), which combines standard transvaginal ultrasonography (TVUS), 3-dimensional (3D) ultrasonography and the use of water for rectal contrast. We also assess the correlation between 3D-RSG and MRI in the diagnosis of rectosigmoid endometriosis. STUDY DESIGN: This study included 50 consecutive women with symptoms suggestive of DIE. After colorectal enema, they underwent a gynecological examination and a 3D TVUS during which 120ml of water was injected in the rectosigmoid to improve the performance of the examination. All patients also underwent an MRI and surgery was offered to the patient if there was discordance between the two procedures. RESULTS: Fifty women underwent 3D-RSG between May and November 2012. All procedures were well tolerated by patients. Two examinations (4%) were stopped for technical reasons. Nineteen rectosigmoid nodules were diagnosed in 18 women (36%). Eighteen of these nodules were also identified on MRI, and one (2%) nodule seen on MRI was not diagnosed by 3D-RSG. In 31 examinations (62%), neither technique identified an intestinal lesion. There was a concordance rate of 96% between the two techniques. Using MRI as the reference technique, 3D-RSG had a sensitivity of 0.95, a specificity of 0.97, a positive predictive values of 0.95, and a negative predictive value of 0.97. There was a 30.3 positive likelihood ratio and a 0.05 negative likelihood ratio. CONCLUSIONS: 3D-RSG seems an interesting new method for diagnosis of rectosigmoid endometriosis and is both feasible and well tolerated. 3D-RSG is highly concordant with MRI in this indication, although further studies are needed to confirm these primary results.
