Comparison of the application value of transvaginal ultrasound and transabdominal ultrasound in the diagnosis of ectopic pregnancy

BACKGROUND Ectopic pregnancy(EP) is one of the most common acute abdominal diseases in gynecology. Once the condition of EP is delayed, it may lead to massive hemorrhage, shock, and even death in a short time, seriously threatening the patient’s life. Early diagnosis is the key to preventing and improving the prognosis of EP.Transabdominal ultrasound(TAS) and transvaginal ultrasound(TVS) are the main diagnostic methods for abdominal diseases. The purpose of this study is to explore the application value and effect of TAS and TVS in the diagnosis of EP,hoping to provide more valuable references for the diagnosis of EP.AIM To explore the application value of TAS and TVS in the diagnosis of EP and to improve the level of clinical diagnosis.METHODS A total of 140 patients with EP admitted to our hospital from July 2018 to July 2020 were selected for this study. All patients were divided into two groups according to the examination methods. 63 patients who underwent abdominal ultrasound examination were set as the TAS group, while 77 patients who underwent TVS examination were set as the TVS group. We compared the diagnostic accuracy and misdiagnosis rates between the two types of ultrasound examinations, as well as the postoperative pathological results of the two diagnostic methods for different types of ectopic pregnancies. We also analyzed the sonograms for the presence of mixed ectopic masses,adnexal masses, ectopic gestational sacs, the presence or absence of visible embryo and fetal heart in the ectopic sac shadow, and the detection of fluid in the rectal fossa of the uterus, such as the adnexal area, yolk sac, and embryo, etc. In addition, the diagnosis time, days of gestational sac appearance, operation time, endometrial thickness, and blood flow resistance index were compared as well.RESULTS After performing both types of ultrasound examinations in 140 patients with EP, we found that the diagnostic accuracy of TVS was significantly higher than that of TAS, and the misdiagnosis rate was significantly lower than that of TAS. The differences were statistically significant(P < 0.05). In addition, the detection rate of TVS was better than that of TAS for the presence of mixed masses,adnexal masses, ectopic gestational sacs, the presence or absence of visible embryo and fetal heart in the shadow of the ectopic sac, and sonograms such as the adnexal area, yolk sac, and embryo,etc. The coincidence rate of its postoperative pathological examination results was significantly higher than those of TAS. The diagnosis time and the days of gestational sac appearance by TVS were significantly shorter than that by TAS, and the operation time was earlier than that by TAS.What’s more, the detection rates of the endometrial thickness ￡ 1.5 mm and blood flow resistance ￡0.5 were significantly higher in TVS diagnosis of EP than in TAS. All differences were statistically significant(P < 0.05).CONCLUSION Compared with TAS, TVS has the advantages of high detection accuracy and good sonogram performance.

Twin fetuses associated with double amniotic sacs diagnosed using transvaginal ultrasonography:A case report

BACKGROUND Conjoined twins are a rare twin malformation commonly presenting as single amniotic sac twinning,with double amniotic sac twinning being extremely rare and poorly reported.Most conjoined twins are females.CASE SUMMARY A woman of childbearing age conceived naturally,and at 8 wk of gestation,transvaginal ultrasonography showed an embryo and cardiac tube pulsation in both amniotic sacs.On dynamic observation,the two embryos were connected in the lower abdomen,with restricted movement.A repeat transvaginal ultrasound at 11 wk showed that the intestinal tubes of both fetuses were connected in the lower abdomen.The pregnancy was terminated and labor was induced.CONCLUSION Transvaginal ultrasound may detect conjoined twin malformations in an early stage.Our case provides diagnostic insights for ultrasonographers and can help develop early therapeutic interventions.

Detection of Congenital Uterine Malformation by Using Transvaginal Three-dimensional Ultrasound

This study assessed the clinical application of transvaginal three-dimensional ultrasound （3D TVUS） in the diagnosis of congenital uterine malformation. A retrospective study was performed on 62 patients with congenital uterine malformation confirmed hysteroscopically and/or laparoscopically. The patients were subjected to transvaginal two-dimensional ultrasound （2D TVUS） and 3D TVUS. The accuracy rate was compared between the two methods. The accuracy rate of 3D TVUS was （98.38%, 61/62）, higher than that of 2D TVUS （80.65%, 50/62）. 3D TVUS coronal plane imaging could demon- strate the internal shape of the endometrial cavity and the external contour of the uterine fundus. It al- lowed accurate measurement on the coronary plane, and could three-dimensionally show the image of cervical tube, thereby providing information for the diagnosis of some complex uterine malformation. 3D TVUS imaging can obtain comprehensive information of the uterus malformation, and it is superior to 2D TVUS for the diagnosis of congenital uterine malformations, especially complex uterine anomaly.

MRI and Transvaginal Ultrasound Findings of Atypical Polypoid Adenomyoma: A Case Report

Atypical polypoid adenomyoma(APA)is an uncommon type of polypoid characterized by fibroid stroma and endometrial glands.It occurs mostly in premenopausal women and rarely in postmenopausal women with irregular vaginal bleeding.In our current case,a 76-year-old woman presented with irregular vaginal bleeding.The final pathological diagnosis of the mass was APA.APA is not easy to diagnose before surgery.On the one hand,there was no obvious particularity in imaging features and clinical features,especially for uncomfortably identifying endometrial cancer.On the other hand,APA has a pedicle,attaching to any part of the uterine cavity,which can cause pseudocoel between the mass with the uterine cavity wall.So,when it comes to getting the pathological tissue in the absence of hysteroscopy,it is easy to access to the pseudocoel and obtain endometrial tissue rather than the pathological tissue of the mass.Therefore,preoperative imaging examination is of great significance diagnosis way of thinking to clinicians for APA.In the meantime,pathological tissue of APA can be obtained by hysteroscopy in visual conditions.

Transvaginal 3D Ultrasound Evaluation of Post-Cesarean Section Uterine Diverticulum

Objectives: This study focused on evaluating the value of transvaginal 3D ultrasound for the diagnosis and prognostic assessment of post-cesarean section uterine diverticulum. Materials and Methods: We retrospectively analyzed the data from 32 patients with post-cesarean section uterine diverticulum over three recent years. In all patients, transvaginal 3D ultrasound was used to measure the size of the uterine diverticulum and the thickness of the lower uterine segment (LUS) and myometrium. Patients with a LUS with a myometrial thickness under 4 mm underwent resection and repair surgery;those with a LUS with a myometrial thickness over 4 mm underwent hysteroscopic resection. The postoperative sonograms were compared with preoperative images to evaluate the efficacy of various treatments. Results: The mean length, width and depth of the uterine diverticula were 18.30 ± 2.80 mm, 9.14 ± 3.20 mm and 11.49 ± 2.71 mm, respectively. The average LUS myometrial thickness was 3.40 ± 0.80 mm (with a range of 1.6 mm - 6.3 mm). After surgery, two patients’ sonograms still showed diverticula at the post-cesarean section scar, measuring 6 mm × 7 mm × 6 mm and 6 mm × 8 mm × 4 mm. There were significant differences in the size of uterine diverticula between preoperative and postoperative sonograms (P < 0.05) and the effective rate of surgery was 93.75% (30/32). Conclusions: Transvaginal 3D ultrasound is an accurate method for detecting post-cesarean section uterine diverticulum and is helpful for assessing surgical options and prognosis. The LUS myometrial thickness, which is considered as an optional index of post-cesarean section uterine diverticulum, should be measured routinely.

The Value of Transvaginal Ultrasound in Clinical Surgical Treatment of Cesarean Scar Pregnancy

The clinical value of transvaginal ultrasound in clinical surgical treatment of cesarean scar pregnancy（CSP） was evaluated. The clinical data of 104 patients with CSP admitted at Tongji Hospital from 2013 to 2016 were collected and analyzed retrospectively, including the patients＇ age, gestational age, the size of gestational sac or uneven mass, the uterine scar thickness, β human chorionic gonadotropin（h CG） levels and so on. Of these 104 cases, 30 cases were subjected to laparotomy, 29 cases to laparoscopy, 27 cases to hysteroscopy, 16 cases to ultrasound-guided uterine curettage, and 2 cases to conservative treatment. The transvaginal ultrasound showed that uterine scar thickness and gestational sac or uneven mass size had significant difference（P〈0.05） among different surgical methods by comparatively analyzing the patients＇ data. It was suggested that transvaginal ultrasound may provide the valuable reference for choosing clinical surgical procedures for CSP.

A Comparative Observational Study of the Use Transvaginal Ultrasound and Hysteroscopy for the Detection of Uterine Cavity Pathologies in Women with Abnormal Uterine Bleeding

Background: 70% of all gynecological consultations are for abnormal uterine bleeding. Any approach to optimal management begins with an appropriate diagnosis. 40% of premenopausal women with abnormal uterine bleeding were found to have some intrauterine pathology. This study aims to compare the diagnostic value of transvaginal ultrasonography in comparison to hysteroscopy in detecting uterine abnormalities in patients with abnormal uterine bleeding. Methods: Retrospective observational cross sectional study of 250 women presented with abnormal uterine bleeding. The patients who fulfilled the selection criteria and have been sequentially investigated by transvaginal ultrasound (TVS) and hysteroscopy were included. Results: 90% of patients were from 35 - 49 yrs. 81.2% of patients have body mass index above 25 kg/m2. Transvaginal ultrasound (TVS) compared well with high sensitivity as regards normal endometrium. (TVS) missed 4 patients of endometrial polyps and one patient of sub mucous fibroid. Three patients of adenomyosis were only diagnosed by (TVS);they were reported as being normal by hysteroscopy. Conclusion: (TVS) is considered as an excellent approach to the initial evaluation of uterine pathologies in patients with abnormal uterine bleeding.

Vaginal Touch versus Transvaginal Ultrasound in the Management of Threatened Preterm Labour at the University Hospital Center of Porto-Novo (Benin)

Objective: To evaluate the risk of preterm delivery with vaginal touch in opposition with transvaginal ultrasound in pregnant women who present signs and symptoms of threatened preterm labour. Methods: A prospective study was conducted with descriptive and comparative aims at the University Hospital of Porto-Novo, Benin Republic between 1 March and 31 August 2016. Every pregnant woman admitted to the emergencies of the maternity between 28 and 34 of WA (weeks of amenorrhoea) and attended for preterm delivery risk with intact membranes was included. The risk of preterm delivery was evaluated using vaginal touch and ultrasound examination of cervical length. Results: The risk of preterm delivery was obvious and identical with the cervical dilatation ≥2 cm when the vaginal touch was applied [RR 2.34 IC 95% (1.71 - 3.20)] and ultrasound examination of cervical length - 4.16)]. The cervix obliteration was not statistically linked to preterm delivery. The ultrasound examination of cervical length had a better sensitivity (87.76%) and a negative predictive value (81.54%) against 59.18% and 74.68% respectively for cervical dilatation at vaginal touch. Bishop score also had a better specificity with the one of the ultrasound examination of cervical length (79.11% vs. 33.54%) whereas both of them had almost identical negative predictive value (81.17% vs. 81.54%). Conclusion: Vaginal touch was also as relevant as transvaginal ultrasound while evaluating the risk of preterm delivery. For the lack of ultrasound in emergency rooms, a good physical examination would be sufficient by its own to decide of an adequate management when there is a threat of preterm delivery.

The Clinical Value of Ultrasound Image Texture Analysis in the Diagnosis of Uterine Adhesions

Purpose: This review examines the diagnostic value of transvaginal 3D ultrasound image texture analysis for the diagnosis of uterine adhesions. Materials and Methods: The total clinical data of 53 patients with uterine adhesions diagnosed by hysteroscopy and the imaging data of transvaginal three-dimensional ultrasound from the Second Affiliated Hospital of Chongqing Medical University from June 2022 to August 2023 were retrospectively analysed. Based on hysteroscopic surgical records, patients were divided into two independent groups: normal endometrium and uterine adhesion sites. The samples were divided into a training set and a test set, and the transvaginal 3D ultrasound was used to outline the region of interest (ROI) and extract texture features for normal endometrium and uterine adhesions based on hysteroscopic surgical recordings, the training set data were feature screened and modelled using lasso regression and cross-validation, and the diagnostic efficacy of the model was assessed by applying the subjects’ operating characteristic (ROC) curves. Results: For each group, 290 texture feature parameters were extracted and three higher values were screened out, and the area under the curve of the constructed ultrasonographic scoring model was 0.658 and 0.720 in the training and test sets, respectively. Conclusion Relative clinical value of transvaginal three-dimensional ultrasound image texture analysis for the diagnosis of uterine adhesions.

Comparison of Bishop score and cervical length measurement through transvaginal ultrasound as prediction against labor induction

Objective:To compare the Bishop score and cervical length measured by transvaginal ultrasound concerned with prediction over the success of labor induction.Methods:This cross-sectional observational analytical study was conducted from May 2017 to October 2017 at several teaching hospitals of Obstetrics and Gynecology Department, Faculty of Medicine Hasanuddin University of Makassar, India. There were 110 samples of pregnant women undergoing labor induction process including 79 samples of successful induction and 31 samples of induction failure. The data analysis used Pearson Chi-square test and multivariate logistic regression to see the effect of Bishop score and measurement of cervical length with successful induction of labor.Results: Number of samples with successful labor induction with Bishop score <3 was 25 (31.6%) and Bishop score≥3 was 54 (68.4%), with rate ratio=3.714 andP=0.000. With measurement of cervical length (cut-off point 2.98 cm), number of samples with successful labor induction with cervical length≤2.98 cm was 12 (15.2%) and cervical length >2.98 cm was 67 (84.8%), with rate ratio=3.124 andP=0.000. Multivahate analysis of logistic regression was found to be more influential in the predicted success of labor induction (P=0.014 with Bishop score <3, odds ratio=1.000 and Bishop score≥3, odds ratio=3.779. Conclusions: Bishop score is better in predicting the success of labor induction compared to the measurement of cervical length through transvaginal ultrasound.

Accuracy of Transvaginal Ultrasound in Prediction of Latency Period in Women with Preterm Premature Rupture of Membranes

Background: Preterm prelabor rupture of membranes (PPROM) is a major cause of Pretem Birth (PTB), Pretem Birth (PTB) is the most significant cause of perinatal morbidity and mortality worldwide. Cervical length (CL), posterior uterocervical angle (PUCA) and anterior uterocervical angle (AUCA) have been postulated in several studies to have an important role in prediction of PTB. Up to our knowledge, this is the first study that combines the three cervical parameters in prediction of latency period in women with PPROM. Aim of the Work: To assess the accuracy of cervical length, posterior uterocervical angle and anterior uterocervical angle in prediction of latency period in women with Preterm prelabor rupture of membranes. Subjects and Methods: A Prospective cohort study on 205 women with PPROM was held at Ain Shams University Maternity Hospital, a transvaginal ultrasound was performed to measure cervical length, posterior uterocervical angle, anterior uterocervical angle. Results: A total of 205 pregnant women with PPROM were included in this study, the latency grade was within 2 days in 57 (27.8%) of cases while was after 2 days in 148 (72.2%) of cases. As regards cervical length cut-off value 25.0 mm, sensitivity was 78.9%, specificity was 65.5%, posterior uterocervical angle cut-off value 108.0°, sensitivity was 93.0%, specificity was 60.1%, and anterior uterocervical angle cut-off value 106.0°, sensitivity was 93.0%, specificity was 71.6%. Conclusion: The combination of cervical length (CL), posterior uterocervical angle (PUCA) and anterior uterocervical angle (AUCA) measurements greatly predicts the latency period in women with PPROM, and Anterior uterocervical angle (AUCA) ≥ 106.0° had the highest diagnostic value in predicting latency period within two days.
