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.

Diagnostic value of different color ultrasound diagnostic method in endometrial lesions

BACKGROUND Endometrial lesions include endometrial cancer and inferior fibroids.Among them,endometrial cancer as a malignant tumor seriously endangers the life and health of patients.Ultrasonography is an important means of diagnosing female reproductive system diseases,and it is of critical value for the early diagnosis of endometrial cancer.However,different ultrasound inspection programs have achieved different results.It is of great significance to choose a suitable inspection program.AIM To explore the diagnostic efficacy of different ultrasonic examination methods in clinical endometrial lesions.METHODS The 140 patients with endometrial lesions who were treated in our hospital from April 2018 to October 2019 were used as the research subjects.All patients underwent transvaginal color ultrasound and transabdominal color ultrasound.We compared the diagnostic coincidence and image display effects of the two different examination methods,and the endometrial thickness,blood flow,uterine effusion and resistance index of different diseases were observed by transvaginal color ultrasound.RESULTS The diagnostic coincidence rate of all types of diseases of transvaginal color ultrasound was significantly higher than that of transabdominal color ultrasound(P=0.001,0.005,0.001 and 0.001).In addition,the excellent and good rate of image display of transvaginal color ultrasound was higher than that of transabdominal color ultrasound(P=0.001).There were significant differences in endometrial thickness in patients with different types of endometrial lesions through the transvaginal color examination(P=0.001).The incidence rate of uterine effusion in patients with endometrial carcinoma was significantly higher than that in patients with other types of endometrial lesions(P=0.001),and the rate of the blood flow was the highest(P=0.001).The comparison of blood flow resistance index indicated that the blood flow resistance index in endometrial cancer patients was the lowest,which shows that the difference was statistically significant(P=0.001).CONCLUSION The overall diagnostic efficacy of transvaginal color ultrasound in the clinical diagnosis of endometrial lesions is better than that of transabdominal color ultrasound,which held higher diagnostic coincidence rate and image display effect.There were significant differences in the thickness of the endometrium and the blood flow in different types of lesions.
