Abstract
Objective:To analyze the application of transabdominal sonography and transvaginal sonography in early diagnosis of pregnancy and to provide a reference for the selection of diagnosis methods in clinic.Methods:One hundred and eighty patients who were admitted into the hospital from February 2013 to February 2014, received clinical diagnosis and were confirmed as ectopic gestation by surgery were selected as research objects. They were examined by transabdominal sonography, transvaginal sonography, and transabdominal sonography in combination with transvaginal sonography respectively. Besides, the ultrasonic performance was observed and compared with surgical pathological results to analyze and compare diagnostic accordance rate.Results:The positive rate of transabdominal sonography in combination with transvaginal sonography was much higher than that of transabdominal sonography and transvaginal sonography and the differences had statistical significance (P<0.05). The detection rate of different positive characteristics using the combined examination was much higher than that of transabdominal sonography and transvaginal sonography, and the differences had statistical significance (P<0.05). The detection rates of different types of ectopic gestation and different sizes of mass using transabdominal sonography in combination of transvaginal sonography were higher than that of transabdominal sonography and transvaginal sonography (P<0.05).Conclusion:Transabdominal sonography in combination with transvaginal sonography can complement information, improve detection rate, and reduce or avoid misdiagnosis and missed diagnosis, which provides a scientific basis for the formulation of clinical treatment scheme.
Highlights
Pregnancy is the most important stage for the development of fetus
Transvaginal sonography could accurately diagnose the existence of gestational sac and yolk membrane as well as the location and size of gestational sac, clearly display embryo, sense original heart beat of fetus and detect out endometrial thickness and the depth of pelvic fluid (Fig.2)
One hundred and sixty-two patients were confirmed with ectopic gestation by transvaginal sonography, and the positive correct diagnosis rate was 90.0%; one hundred and forty-three patients were confirmed with ectopic gestation by transabdominal sonography, and the positive confirmed diagnosis rate was 79.4%; one hundred and seventy-four patients were confirmed with ectopic gestation by transvaginal sonography in combination with transabdominal sonography, and the positive confirmed diagnosis rate was 96.7%
Summary
Ultrasonic examination indications for early pregnancy include the existence of uterine pregnancy, the number of gestation sac, and the existence of ectopic gestation.[1] Ectopic gestation is a commonly seen acute abdominal disease and a cause for the death of pregnant women. Gestation refers to the process of implantation and development of fertilized ovum. If fertilized ovum implants in the site beyond uterus, it is called ectopic gestation.[2,3] Currently, the incidence of ectopic gestation tends to be higher year by year,[4] and the disease is not specific in the early stage. Massive haemorrhage may be induced if gestational sac breaks; and adverse symptoms such as acute abdominal disease and shock can happen in severe case, which can severely threaten the life safety of patients.[5] early diagnosis is of great significance
