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. 展开更多

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. 展开更多

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. 展开更多

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. 展开更多

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. 展开更多

Abdominal pregnancy is a rare and life-threatening form of ectopic pregnancy.It is defined as an ectopic pregnancy in a region of the peritoneal cavity that does not include the fallopian tubes,ovaries,or their associated ligamentous structures.Many abdominal pregnancies are caused by secondary implantation in the peritoneal cavity after tubal abortion,rupture,or uterine rupture.Here,we report a case of abdominal pregnancy resulting from iatrogenic uterine perforation during the induced abortion of an early intrauterine pregnancy,which had been misdiagnosed as a ruptured corpus luteum cyst due to the sudden rupture of the abdominal gestational sac,complicating intra-abdominal hemorrhage.The true diagnosis was missed by vaginal ultrasound and confirmed by laparoscopic exploration.We discuss the details of the case management and review the relevant literature.©2023 Zhejiang University. 展开更多

Background: Retention of fetal bones is a rare cause of abnormal uterine bleeding. Others may present as subfertility, chronic pelvic pain, abnormal vaginal discharge, menometrorrhagia, dysmenorrhea and spontaneous expulsion of bony fragments. Incidence is 0.26% among patients undergoing hysteroscopy. Aim: To document a pattern of presentation of retained fetal bone and its management. Case Presentation: Our patient is an 18-year old who presented with vaginal bleeding of four weeks duration and managed for abnormal uterine bleeding due to retained fetal bone following second trimester abortion. Conclusion: The use of transvaginal ultrasound in making diagnosis of retained fetal bone is effective. Treatment by removal of bones through evacuation by dilatation and curettage or hysteroscopy brings about resolution of symptoms. Use of pelvic ultrasonography to confirm complete evacuation of the uterus after abortion especially second trimester abortion could aid in early diagnosis and management of incomplete abortion. 展开更多

BACKGROUND Intramural pregnancy is a rare type of ectopic pregnancy,which is diagnosed by transvaginal ultrasound and magnetic resonance imaging.Management strategies vary depending on the site of the pregnancy,the gestational age and the desire to maintain fertility.The incidence of intramural pregnancy in assisted reproductive technology is higher than that in natural pregnancy.CASE SUMMARY We present a case of intramural pregnancy after in vitro fertilization and elective single embryo transfer following salpingectomy.The patient was completely asymptomatic and her serumβ-human chorionic gonadotropin level increased from 290 m IU/m L to 1759 m IU/m L.Three-dimensional transvaginal ultrasound indicated a heterogeneous echogenic mass arising from the uterine fundus which was surrounded by myometrium and a slender and extremely hypoechoic area stretching to the uterine cavity which was thought to be a fistulous tract.Therefore,we considered a diagnosis of intramural pregnancy and laparoscopic surgery was conducted at 7 wk gestation.CONCLUSION Early diagnosis and treatment of intramural pregnancy is significant for maintaining fertility. 展开更多

Objective To investigate the immediate effects of electro-acupuncture(EA)on endometrial blood flow among recurrent implantation failure(RIF)patients.Methods Eighty RIF patients,enrolled from March 2022 to December 2022,were randomly allocated into either the EA group(40 cases)or the waiting-list(WL)group(40 cases)by using a random number table.The EA group underwent acupuncture at points of Shenting(GV 24),Baihui(GV 4),Benshen(GB 13),bilateral Zigong(EX-CA 1),Huangshu(KI 16),Sanyinjiao(SP 6)and Xuehai(SP10),and electric acupuncture apparatus was connected to EX-CA 1,KI 16,SP 6,and SP 10 with disperse-dense waves at 4/20 Hz frequencies for 30 min after transvaginal ultrasound,while the WL group received no intervention.The primary outcome measured was the endometrial volume blood flow.The secondary outcomes included the bilateral uterine artery index,endometrial volume,endometrial blood flow type,vascular distribution index(VI^(MV))for endometrial and ovary,clinical pregnancy rate,and embryo implantation rate.Results In the EA group,there was a notable decrease in the bilateral pulsatility index and a significant improvement in the endometrial blood flow type post-EA(P<0.05).Both the endometrial blood flow type and VI^(MV) for the endometrium and right ovary were markedly higher in the EA group compared to the WL group post-treatment(P<0.05).Conversely,no significant disparities were observed in vascular index,flow index,vascular blood flow index,uterine arterial blood flow indices,endometrial volume,clinical pregnancy rate and embryo implantation rate between the two groups after treatment(P>0.05).Besides,no adverse events related to EA were observed.Conclusions EA can promptly ameliorate VI^(MV) for the endometrial and right ovary,and endometrial blood flow type.Future randomized controlled trials are warranted to investigate the long-term effects of EA on blood flow of RIF patients and its implications for pregnancy outcomes.(Trial registration No.ChiCTR2200057377). 展开更多
