Endometrioid carcinoma of the fallopian tube misdiagnosed as an infected endometrioma: A case report.

INTRODUCTION: Fallopian tube cancer is a rare tumor, representing between 0.3 and 1.8 % of all malignant tumors in the gynecological sphere. Due to the proximity of the uterus and ovary, the diagnosis of primary fallopian tube cancer is very difficult to establish and relies on very strict criteria. The endometrioid form is exceptional and of controversial etiopathogenesis. Only a few cases have been previously reported. Diagnosis most often occurs incidentally during histological examination. This case presents a distinctive aspect with the rare occurrence of endometrioid-type fallopian tube cancer, notably associated with endometriosis, and initially misdiagnosed as an infected endometrioma. It underscores the diagnostic complexities encountered in identifying primary fallopian tube cancer. CASE REPORT: We present the case of a 49-year-old patient, followed for chronic pelvic pain associated with menorrhagia. Imaging revealed a myomatous and adenomyotic uterus, a right ovarian endometrioma, and a left multicystic ovarian formation with thick walls, measuring 135 mm, requiring histological verification. She underwent an exploratory laparotomy. During the procedure, extensive retro- and supravaginal adhesive tissue involving the uterus, both adnexa, and the digestive tract was found. Careful adhesiolysis was performed. The left adnexa harbored a formation suggestive of an infected endometrioma. A total hysterectomy with bilateral adnexectomy and peritoneal washing was performed. The postoperative course was uneventful. Histopathological examination revealed an endometrioid carcinoma of the left fallopian tube, classified as pT1a according to FIGO guidelines. DISCUSSION: Tubal cancer is a rare cancer of unknown etiology, underestimated, and sometimes confused with ovarian pathology. Preoperative diagnosis is difficult because the clinical presentation is polymorphic and imaging is nonspecific. The endometrioid form is exceptional and of controversial etiopathogenesis. Treatment mirrors that of malignant epithelial ovarian tumors, with prognosis depending on FIGO stage and histological type. CONCLUSION: Due to its unpredictable nature, fallopian tube cancer should not be overlooked as a differential diagnosis for any adnexal mass.

Regulated Expiratory Methods During Childbirth Process: A Randomized Controlled Trial.

OBJECTIVES: To evaluate the impact of a regulated expiratory method (REM) on the childbirth process. METHODS: This was a randomized trial. Study population included all first-time mothers with a spontaneous onset of labour, at an early stage, and a fetus in cephalic presentation with a normal weight for gestational age. The evaluated intervention was REM based on the use of a specific device. The primary outcome was the cesarean delivery rate. Secondary outcomes included first and second stages of labour times, rates of spontaneous and instrumental vaginal births, and pain scores. Subjective qualitative outcomes related to childbirth experience were evaluated via 2 interviews conducted with the parturient and the midwife responsible for her delivery. Intention-to-treat analysis was employed to compare the 2 groups. RESULTS: The reduction in primary cesarean rates between the 2 groups was not significant (26.7% in control group vs. 18.3% in intervention group; P = 0.274). However, REM allowed for a significant reduction in second stage (P = 0.039) and pushing effort times (P = 0.003). According to midwives, REM had a significant positive impact on parturients' breathing (P < 0.0001) and pushing effort intensity (P = 0.041). It facilitated communication with the parturient (P = 0.002). Moreover, the evaluated method had a significant positive impact on patient's childbirth experience. CONCLUSIONS: Although the reduction in immediate cesarean rates was not significant, REM has the potential to shorten labour duration, improve pain management, and ultimately improve maternal childbirth experience.

Intra-uterine packing: an effective and affordable tool in the management of post-partum hemorrhage - cohort study.

Introduction: postpartum hemorrhage is the main cause of maternal death worldwide. Uterine balloon packing has shown promising outcomes in PPH management. Nevertheless, its usage is limited in low- and middle-income countries due to associated costs. Uterine packing using gauzes presents a potentially efficient and cost-effective alternative. This study aims to assess the safety and efficacy of intra-uterine packing with gauzes in managing postpartum hemorrhage. Methods: this was a retrospective study over a period of two years and six months. All patients who experienced PPH due to uterine atony during vaginal delivery, with no response to medical first-line treatment, were included. IUP using gauze was employed as a second-line intervention. The primary outcome was the success of postpartum hemorrhage management. Secondary outcomes included patient vitals, the need for blood transfusion, change in hemoglobin levels (delta Hemoglobin), and maternal morbidity (post-partum infection, Sheehan syndrome, and retained gauzes). Results: the study included 63 patients. The mean age was 30.06 ± 5.6, the mean gravida was 2.65 ± 1.9 and the mean para was 2.12 ± 1.31. None of these patients experienced major complications following gauze insertion. Three patients underwent laparotomy and conservative surgical management was performed. Hysterectomy was not required for any participant, and no maternal deaths were recorded.

Sepsis-associated encephalopathy and uterine necrosis revealing HIV infection after artery ligation and uterine compression sutures: Case report.

INTRODUCTION AND IMPORTANCE: Infection with the human immunodeficiency virus (HIV) targets immune cells and exposes infected patients to several diseases. For these reasons, HIV infection should be suspected in each situation where post-operative sepsis occurs, to afford therapy and improve the patient's prognosis. CASE PRESENTATION: We present a case of a pregnant woman at 39 weeks of gestation who missed her prenatal follow-up. She underwent an emergency caesarian section for severe abnormality in the fetal heart rate. The caesarian section was complicated by a post-partum hemorrhage (PPH). PPH was managed with uterine artery ligation and B-Lynch modified sutures. CLINICAL DISCUSSION: Postoperatively, there was the succession of the following events: purulent uterine necrosis, peritonitis, and encephalitis leading to a life-saving hysterectomy. Due to the worsening of the septic condition, HIV screening was performed, after obtaining the patient's consent, and came back positive. CONCLUSION: The aim of this case report is to push practicians to think about HIV infection when necessary because missing the diagnosis can seriously threaten patients' health.

Infected, giant borderline ovarian tumor: A case report.

INTRODUCTION AND IMPORTANCE: Gigantic borderline ovarian cancer, also known as giant borderline ovarian tumor, is a rare subtype of borderline ovarian cancer. This type of ovarian cyst can be associated to various complication, including superinfection. CASE PRESENTATION: We present the case of a 30-year-old woman who sought medical attention due to chronic abdominal pain and a rapid increase in abdominal girth over the past four months. Pelvic ultrasound and pelvic magnetic resonance imaging (MRI) revealed an abdominal-pelvic mass of 27 ∗ 12 cm. The tumoral markers were elevated. During her hospitalization, she developed a fever along with abdominal pain and biological inflammatory syndrome. Surgical intervention a 30-cm-long solid cystic mass located on the right ovary, accompanied by moderate ascites. The surgical procedure included a right adnexectomy, omentectomy, and appendicectomy, with cytology performed. Postoperative antibiotics were administered, and the patient showed favorable clinical and biological progress. The anatomopathological examination confirmed a 35-cm borderline mucinous tumor with signs of infection. CLINICAL DISCUSSION: Giant borderline ovarian tumor is characterized by the presence of an ovarian mass measuring at least 10 cm in diameter. Infectious complications are rare, and their clinical features usually mimic those of a peritonitis. Treatment is based on antibiotics and chirurgical removal of the tumor based on the FIGO classification along with peritoneal biopsies and cytology. CONCLUSION: This study explores the diagnosis, treatment, and prognosis of infected giant borderline ovarian tumors.

Anxiety and Depression Symptoms in At-Risk Pregnancy: Influence on Maternal-Fetal Attachment in Tunisia.

OBJECTIVES: To investigate maternal prenatal anxiety and depression in high-risk pregnancies and examine their influence on maternal-fetal attachment. METHODS: We included 95 hospitalized high-risk pregnant women. The Hospital Anxiety and Depression Scale (HADS) and the Prenatal Attachment Inventory (PAI) were used to assess the primary objective. Internal consistency and construct validity of the PAI were investigated. RESULTS: The average age was 31 years and gestational age ranged from 26 to 41 weeks. Prevalence of depressive symptoms was 20% and anxiety symptoms 39%. Cronbach alpha coefficient of the PAI Tunisian version was 0.8 and the construct validity in favour of one factor model. PAI scores correlated negatively and significatively with the HADS total score (r = - 0.218, p = 0.034) and was attributed to the depression dimension only (r = - 0.205, p = 0.046). CONCLUSIONS FOR PRACTICE: Emotional wellbeing of pregnant women especially in high-risk pregnancies should be explored in order to prevent consequences on women, their growing fetus, and prenatal attachment.

What is already known? Maternal prenatal emotional well-being influences maternal­fetal attachment which has important implications on postnatal bonding. Anxiety and depression disorders during pregnancy could affect women's attachment to their unborn child in a negative way. Research has largely been conducted with the general pregnant population with little focus on at-risk pregnancies, which are associated with increased levels of mood disorders. What this paper adds? This study highlights the impact of depression but not situational anxiety on maternal­fetal attachment in women with high-risk pregnancies, highlighting the importance of assessing and managing psychological disorders during pregnancy to enhance the quality of prenatal bonding.

Impact of purse-string uterine suture on scar healing after a cesarean delivery: a randomized controlled trial.

BACKGROUND: Uterine closure technique can affect scar healing, potentially resulting in unfavorable gynecologic and life-threatening obstetrical outcomes. Double-layer continuous unlocked suture has been demonstrated to promote optimal residual myometrial thickness. Recently, the purse-string uterine suture technique has emerged as a viable method to enhance the healing of scars. However, the current lack of randomized trials assessing the relevance of this technique warrants further investigation. OBJECTIVE: This study aimed to evaluate the impact of purse-string uterine sutures on scar healing after cesarean delivery when compared with double-layer continuous unlocked suture. STUDY DESIGN: This was a randomized controlled trial; 126 patients with singleton pregnancies undergoing primary cesarean delivery were enrolled in 2 groups. The primary outcome was the mean residual myometrial thickness measured by saline infusion sonography 6 months after surgery by 2 sonographers blinded to uterine closure techniques. Operative time, calculated blood loss, total number of needed threads, and perioperative scar width were used for the perioperative analysis. Healing ratio and cesarean scar defect measurements were used for the 6-month analysis. RESULTS: There was no significant difference in terms of residual myometrial thickness (9.38±2.3 vs 8.4±3.9 mm; P=.187), blood loss (540 [146-982] vs 495 [241-903] mL; P=.815), or operative time (6.2 [5.2-7] vs 6 [5.3-7] minutes; P=.977). Achievement of purse-string uterine suture required significantly fewer threads (1 [1-1] vs 2 [1-2]; P<.001) and fewer hemostatic complementary sutures (1 [1-1] vs 1 [1-2]; P=.013). Scar width was significantly lower with purse-string uterine sutures (50 [40.5-50.5] vs 70 [60-70.5] mm; P<.0001). Purse-string uterine sutures allowed a higher healing ratio (1 [0.9-1] vs 0.84 [0.59-1]; P=.003) and significantly fewer cesarean scar defects (12% vs 35%; P=.018) compared with double-layer continuous unlocked suture. CONCLUSION: Despite resulting in no difference in residual myometrial thickness, purse-string uterine closure seems to be associated with better uterine scar healing on the basis of a higher healing ratio, and a lower rate of cesarean scar defects compared with double-layer continuous unlocked suture.

Early versus late amniotomy during induction of labor using oxytocin: A randomized controlled trial.

OBJECTIVE: To assess the effect of early amniotomy on labor duration, maternal and neonatal outcomes during induction of labor (IOL). METHODS: This was a randomized controlled trial, conducted over a period of eight months at a monocentric site. Singleton pregnancies in nulliparous and parous patients with cephalic presentation and Bishop score ≥ 6 were enrolled in the study. One hundred participants were randomized into two groups: early amniotomy (initiating IOL with amniotomy followed by oxytocin) versus late amniotomy (initiating IOL with oxytocin followed by amniotomy 4 hours later). The primary endpoint was the time to active phase (cervical dilation ≥ 5 cm) during IOL. Secondary outcomes were time to vaginal delivery, mode of delivery, and maternal and fetal outcomes. RESULTS: Early amniotomy reduced time to active phase by 2 hours and 46 minutes compared to the late amniotomy group (3 h 42 min vs. 6 h 28 min; p<0.0001). It also reduced time to vaginal delivery by 2 hours and 52 minutes (5 h 17 min vs. 8 h 9 min; p = 0.0003). The rate of cesarean section (CS) for failed IOL was significantly lower in the early amniotomy group (31.2% vs. 70.0%; p = 0.02), without any significant difference in the overall rate of cesarean section between the two groups (32.0% vs. 40.8%; p = 0.36). There was no significant difference in maternal or fetal outcomes. CONCLUSIONS: Early amniotomy in IOL significantly shortens the time to active phase as well as the overall duration of labor without compromising maternal and neonatal safety.

Double-layered purse string uterine suture compared with single-layer continuous uterine suture: A randomized Controlled trial.

BACKGROUND: With the aim of preventing cesarean scar defects, we introduced a new technique involving a purse string uterine suture. To date, this uterine suture technique has not been formally evaluated. The objective of the study was to test the hypothesis that compared to single layer continuous uterine suture (SLCUS), a double layered purse string uterine suture (PSUS) significantly reduces cesarean scar defect (CSD) rates, without increasing the perioperative maternal morbidity. METHODS: A prospective randomized study. Primary outcome was the rate of CSD. 100 patients were enrolled in 2 groups according to the uterine suture technique. A hysterosonography was performed by the same senior obstetrician blinded to the uterine suture technique 6 months after surgery .Operative time and calculated blood loss (CBL) were used for the short time analysis. Uterine and CSD measurements were used for the mid time analysis. RESULTS: Despite a longer operative time with PSUS (7.17 ± 2.31 min Vs. 6.31 ± 3.04 min, p = 0.028; p <10‾³); there was no significant difference in terms of CBL (520 ± 58 with PSUS vs. 536 ± 50 ml, p = 0.724). There was a significant decrease in the rate of CSD with PSUS: 6.66% Vs.40% with SLUCS; p<0.001. Moreover, SLUCS was the leading risk factor for CSD: adjusted OR=6; 95% CI [0-1], p<10‾³). CONCLUSION: Compared to single layer continuous suture, double layered purse stringuterine suture significantly reduces cesarean scar defect rates, without increasing the perioperative maternal morbidity.

The extraperitoneal French AmbUlatory cesarean section technique leads to improved pain scores and a faster maternal autonomy compared with the intraperitoneal Misgav Ladach technique: A prospective randomized controlled trial.

OBJECTIVE: To determine whether the French AmbUlatory Cesarean Section (FAUCS) technique reduces postoperative pain and promotes maternal autonomy compared with the Misgav Ladach cesarean section (MLCS) technique in elective conditions. STUDY DESIGN: One hundred pregnant women were randomly, but in a non-blinded manner, assigned to undergo FAUCS or MLCS. The primary outcome was a postoperative mean pain score (PMPS), and secondary outcomes were a combined pain/medication score, time to regain autonomy, surgical duration, calculated blood loss, surgical complications, and neonatal outcome. RESULTS: Women in the FAUCS group experienced less pain than those in the MLCS group (PMPS = 1.87 [1.04-2.41] vs. 2.93 [2.46-3.75], respectively; p < 0.001). Six hours after surgery, the combined pain/medication score for FAUCS patients was 33% lower than that for MLCS patients (p < 0.001). FAUCS patients more rapidly regained autonomy, with 94% reaching autonomy within 12 h vs. 4% of MLCS patients (p < 0.001). There were no differences in maternal surgical or neonatal complications between groups. CONCLUSIONS: Our results indicate that FAUCS can reduce postoperative pain and accelerate recovery, suggesting that this technique might be superior to MLCS and should be more widely used. One potentially key difference between FAUCS and MLCS is that MLCS includes 100 mcg spinal morphine anesthesia in addition to the same anesthesia used by FAUCS. Any interpretation of apparent differences must take the presence/absence of morphine into account.

[CD10 expression in stromal cells of patients with breast cancer: a poor prognostic marker]. / Expression stromale de CD10 dans les cancers du sein: marqueur de mauvais pronostic.

INTRODUCTION: markers in breast cancer stem cells, such as cluster of differentiation 10 (CD10), would be correlated with invasive and metastatic potential of several types of cancer, contributing to tumor growth and metastases. In patients with breast cancer, its prognostic value is still controversial, given the discrepancy of results. The purpose of the study was to study CD10 expression in stromal cells of patients with breast cancer as well as to evaluate the prognostic value of this expression. METHOD: we conducted a retrospective, descriptive and prognostic study. It involved 57 patients with invasive cancer of no special type, whose data were collected in the Department of Pathological Anatomy at the Mongi Slim Hospital over a 38-month period. CD10 expression was studied immunohistochemically and interpreted by semi-quantitative scoring system based on three categories with thresholds of 10 and 30%. RESULTS: the average age of patients was 56.4 years. Twenty-eight patients (49%) had labeled CD10 stromal, half of patients had a score of 1 (low) and the other half had 2 (high). This labeling significantly reduced recurrence-free survival (p=0.001). However, it had no influence on overall survival (p=0.84). The correlation study showed that CD10 expression in stromal cells was significantly correlated with 12 poor prognostic factors in patients with breast cancer. CONCLUSION: CD10 expression in stromal cells of invasive breast cancer is a poor prognostic factor, predictive of poor survival without recurrence and associated with a high invasive and metastatic potential.

Tunisian Women's childbirth experience.

BACKGROUND: The current international context considers birth experiences as a focal point for women's health. However, this subject is rarely discussed in Tunisian literature. AIM: Analyze birth experience of a sample of Tunisian women. METHODS: Transverse descriptive study. All women who gave birth in the study unit during August 2018 were included. A direct interview was conducted during the first postpartum day. The questionnaire used was developed by a multidisciplinary team and included 55 questions, divided into 4 items. We compared the group of women who described their delivery as physically or psychologically traumatic to the group of women who reported a serene birth experience.    A multivariate analysis of variance was used to identify the variables that can influence childbirth experience. RESULTS: During the study period, 170 women were included with a response rate of 81%. Severe anxiety about delivery was reported by 74.5% (n = 127) of women. Delivery was experienced as a trauma in 48.2% (n = 82) of cases. In the group of women who expressed a negative experience, we found a significant association with the use of media and internet as a source of information (p=0.001) and repeated vaginal examinations (p=0.001). Pain significantly impacted women's experience (p = 0.02). Finally, main risk factors of a negative childbirth experience were: uterine revision: OR=7.04 95%CI [0.27-177.68]; Emergency caesarean section: OR=3.04 95%CI [0.94-9.85] and vaginal delivery: OR=2.13 95%CI [0.45-10.14]. CONCLUSION: We can intervene on modifiable factors with the introduction of a specific program preparing women for their childbirth and the improvement of the professional practices. However, the issue will benefit from being discussed and addressed at the national, cultural and societal levels.

French ambulatory cesarean: Mother and newborn safety.

OBJECTIVE: To evaluate mother and newborn child safety after French ambulatory cesarean (FAUCS). METHODS: Prospective comparative cohort study in Tunisia (January-June 2018). Pregnant women indicated for primary or repeat cesarean at term underwent FAUCS or Misgav Ladach cesarean (MLC). Surgical outcomes, overall morbidity, and maternal autonomy during recovery were compared. RESULTS: Among 112 deliveries, 60 were performed by FAUCS and 52 by MLC. FAUCS was feasible in all cases; surgeons achieved a completely extraperitoneal approach in 39 (65.0%) cases. The main difficulty experienced was fetal extraction. Longer operative procedures were recorded in the FAUCS group; however, women in the FAUCS group reported lower pain scores (3 [2-5] vs 4 [3.7-5], P<0.001) and were more likely to decline analgesics (10 [17.0%] vs 0 [0%], P<0.001). They experienced greater autonomy during recovery (median [interquartile range] time to standing, 2 [1.0-2.5] vs 12.8 [8.9-17.9] hours, P<0.001; time to full meal, 4 [3-6[ vs 26.5 [21-31] hours, P<0.001; effective time to hospital discharge, 1 [1, 2] vs 2 [2, 3] days; P<0.001). CONCLUSION: Implementation of the FAUCS technique was safe and successful, and improved maternal condition after cesarean. These short-term results need long-term validation by randomized trials.

Severe gestational hypertriglyceridemia: a rare but serious situation.

The severe hypertriglyceridemia during pregnancy is a rare condition. It is a problem for diagnostic, prognostic and therapeutic. This dyslipidemia benefit from specific and effective treatments, but it is still poorly codified. Dietary is still the essential therapeutic, but fetal extraction should also be considered if the gestational age permits. Post-partum monitoring is required but etiologic thorough is not recommended if the triglycerides rate normalizes. The major complication of hypertriglyceridemia should be actively sought because of important maternal mortality rate.

Diagnosis of fetal occiput position using transperineal ultrasound.

OBJECTIVE: To compare Transperineal (TP) and Transabdominal (TA) ultrasound in the assessment of fetal head position during the second stage of labor. METHOD: A prospective comparative Study including low risk parturients. The assessment of fetal head position was performed for each patient at full dilation. The ultrasound examination was performed by one examiner using TP technique first then TA. A routine digital vaginal examination was performed by a different examiner blinded to ultrasound findings. Considering TA as reference, the three methods were compared. RESULTS: Fifty two patients were enrolled in the study group. Agreement between the clinical examination and TA ultrasound was average with Kappa index = 0.579. Agreement between TA and TP Ultrasound was good with Kappa index = 0.766. TP technique was accurate in the diagnosis of fetal head position (sensitivity =91.3%, specificity=98.38%, PPV=87.5%, NPV=98.91%). TA ultrasound was the most reliable method in case of high presentations. For lower fetal presentations, the TP approach was more relevant. CONCLUSIONS: Assuming that an accurate diagnosis of fetal head position is required before any instrumental delivery where, by definition, fetal presentation is engaged, the TP ultrasound is advised. In a single time this technique provides the necessary information about the station, and the position of the fetal head.

Successful management of acquired uterine arteriovenous malformation.

Uterine arteriovenous malformation (UAVM) is uncommon. They are usually acquired, due to previous intra uterine trauma. We report a case of acquired UAVM in a 28-years-old patient after a medical abortion, diagnosed with ultrasonography and successfully managed with uterine artery embolization.

How to adapt first trimester ultrasound education to Tunisian trainees.

OBJECTIVES: To evaluate the impact of a targeted training program on the quality of NT measures performed by OBST/GYN trainees. METHODS: Prospective study. Step1: each trainee achieved 10 T1US . All were evaluated by 2 experts. Step 2: interactive training session where participants received a detailed feedback report. Step3: each candidate performed again 10 T1US. The results obtained before and after the training session were compared. RESULTS: Step1: Herman score was 4.1 with 38% of unacceptable exams. There was no correlation between the score and the level of the training curriculum. Main difficulty was about obtaining sagittal plane. Step2: self-assigned score before the session overestimated image quality (4.5 Vs. 4.1, p=0.03). At the end of the session, It decreased to 3.1. Step3: a significant improvement of technical settings, mean score (5.4 Vs. 4.1; p <0.001) , percentage of acceptable images (85% Vs. 62%, p = 0.002) and sagittal plane (6.4% Vs. 2.9%; p = 0.003). Only 37% had significantly improved their scores. CONCLUSION: The training program evaluated in this study guides the trainee in his daily self-evaluation. This preliminary study can already open discussion on the education and quality control of the T1US in our country.

Ultrasound monitoring of cervical length in twin Pregnancies.

BACKGROUND: Preterm delivery is the major cause of adverse outcomes in twin pregnancy.  A shortened cervix at 20-24 weeks of amenorrhea is a good predictor of preterm birth in asymptomatic patients. However, there are no recommendations for serial cervical length measurements for these high risk pregnancies. OBJECTIVES: To evaluate the benefits from monthly cervical length monitoring in asymptomatic twin pregnancies. METHODS: This was a prospective study. We compared two groups of twin pregnancies (groupe 1: patients with a monthly and systematic transvaginal ultrasound measurement of the cervical length and groupe2 : patients without monitoring of cervical length) in terms of premature labor screening, mean gestational age at the diagnosis of preterm labor, time saved by tocolysis in case of preterm labor and  mean gestational age at delivery. RESULTS: Ninety nine twin pregnancies were included: 35 patients had a systematic, monthly cervical length (group1) and 64 women had a traditional prenatal care without monitoring of cervical length (group2). A significant relationship between a cervical length measured between 22 and 24 weeks of amenorrhea inferior to 30 mm and preterm labor with a high specificity (100%) and a high positive predictive value (100%). The sensitivity remains average (45%).A significant benefit was demonstrated through this systematic ultrasound measurement of cervical length for the screening of preterm labor (p=0.018), the time saved by tocolysis (p=0.023), as well as the medium gestational age at birth (p=0.046). CONCLUSION: Serial cervical length measurements seems to be a significant predictor of early preterm birth in asymptomatic twin pregnancies.

Performance of ultrasound fetal weight estimation in twins.

BACKGROUND: Ultrasonography is an essential tool in the management of twin pregnancies. Fetal weight estimation is useful to anticipate neonatal care in case of weight restriction or growth discordance. AIMS: To assess the accuracy of estimated fetal weight (EFW) in twins and to assess the accuracy of sonographic examination to predict birth weight discordance (BWD) and small birth weight (SBW).    Methods : This was  a longitudinal prospective study over a period of one year. We have included 50 twin pregnancies with a first trimester ultrasound calculated term and specified chorionicity. An ultrasound EFW was scheduled for all patients within an interval of 4 days before delivery. We calculated the differences between EFW and BW in terms of absolute difference and percentage error. We studied the correlation and the agreement between EFW and BW. Finally we calculated the sensitivity, the specificity, PPV and NPV of ultrasound in the diagnosis of BWD and SBW. RESULTS: Absolute differences between BWF and BW were similar for the two twins. The relative difference was 7.7% [0-32] for T1 and 8.2% [0-27] for T2. The margin of error was greater than 10% in 38% of the cases for T1 and in 34% of cases for T2. Furthermore, correlation coefficients R1 and R2 for T1 and T2 were close to 1; R 1 =0.87 and  R 2 = 0.89. Linear regression analysis allowed us to calculate the birth weight based on the estimated weight and this according to the following equations: For the first twin BW T1 = 0.846 * EFW 415,57+ T1 For the second twin BW T2 = 65.68 + 0.963 * EFW T2 in 34% of cases for T2. Chorionicity, presentation and gestational age did not affect the estimations. Ultrasonography in the diagnosis of SBW had a sensitivity of 90.32%, a specificity of 76.82%, a (PPV) of 80% and a (VPN) of 87%. The performance of ultrasound in the diagnosis of BWD varied according to the adopted threshold. CONCLUSION: Ultrasound is an effective examination to estimate twins weight. Regarding prenatal diagnosis of birth weight discordance, the relevance of this examination increases with the adopted threshold.
