I. Objective: The value of transvaginal ultrasound hormone testing in the diagnosis of polycystic ovary syndrome. Second, the classification of ectopic pregnancy: ectopic pregnancy refers to the abnormal pregnancy process in which the pregnant egg is developed outside the uterine cavity, and there are two major categories: one is extrauterine pregnancy (including tubal pregnancy, interstitial tubal pregnancy, ovarian pregnancy, residual angular uterine pregnancy, abdominal pregnancy) and the other is intrauterine pregnancy (including angular uterine pregnancy, isthmus pregnancy, cervical pregnancy). occurring in the ovaries, abdominal cavity, broad ligament and cervix in about 5% of cases. Tubal pregnancy. Most patients have a history of amenorrhea, a few patients have a small amount of vaginal bleeding resembling menstruation and pregnancy reaction after menopause, some patients have vague pain or soreness on one side of the lower abdomen and positive urine pregnancy test. The abdominal pain after rupture is the main symptom, which is caused by intra-abdominal bleeding and irritation of peritoneum. Patients suddenly feel tearing pain or paroxysmal pain on one side of the lower abdomen, often accompanied by nausea and vomiting. When blood accumulates in the rectal fossa of the uterus, it causes anal cramping and a feeling of defecation. When there is a lot of bleeding, fainting or shock may occur. After termination of tubal pregnancy, there is often irregular vaginal bleeding, but it does not exceed the menstrual volume. It is one of the common acute abdominal conditions in gynecology, and the worldwide incidence has increased from 0.5% to 1%-2% today [1]. Because of its high incidence and serious risk to women’s life and health, it is one of the main causes of maternal mortality, therefore, early and accurate diagnosis is an urgent clinical problem to be solved. With the continuous development of ultrasound technology, early diagnosis of ectopic pregnancy has become possible [2]. In particular, the advancement and use of vaginal ultrasound technology has led to an increasing rate of early diagnosis of ectopic pregnancy. In this paper, we review and analyze the clinical data of 86 patients diagnosed with ectopic pregnancy by two methods of transvaginal and transabdominal color Doppler ultrasonography from October 2009 to September 2010 in our hospital, and compare the clinical diagnostic effects of the two examination methods after surgical and pathological confirmation, so as to provide reference for early diagnosis of ectopic pregnancy by ultrasound in the future. The results are reported as follows. III. Clinical data Methods: 1. Among the suspected ectopic pregnancy patients diagnosed by ultrasonography and pathologically confirmed after surgery, all had a history of sexual intercourse, 31-83 days of menopause, all had vague pain in the lower abdomen and irregular vaginal bleeding in 48 cases, and a few patients had early pregnancy reaction and anal cramping. Urine HCG was positive in all cases, among which 3 cases were weakly positive. There were 46 cases diagnosed by vaginal ultrasound and 40 cases diagnosed by abdominal ultrasound. 2. Ultrasound examination methods: two diagnostic methods, vaginal ultrasound and abdominal ultrasound, were used. The instrument was a Japanese ALOKAa5 ultrasound diagnostic instrument with a transabdominal probe frequency of 3.5 MHZ and a vaginal probe frequency of 6.5 MHz. Abdominal ultrasound examination method: After filling the bladder of all patients, the probe was coated with sterilized coupling agent for multi-directional examination in the lower abdomen, such as longitudinal, transverse and oblique sections. Vaginal ultrasound examination method: After all patients have emptied their bladders, the bladder is placed in a truncated position, the vaginal probe is coated with disposable disinfectant coupling agent and then a disposable disinfectant condom is placed slowly into the vagina for longitudinal and transverse multi-directional scanning, both of which require routine observation of uterine size, endometrial thickness, clarity of the endometrium and the presence or absence of separation, the presence or absence of intrauterine gestational sacs and desmoplasia, and the accumulation of fluid in the rectal fossa of the uterus; abdominal ultrasound also has observation of the interstitial liver and kidney and the interstitial spleen and kidney and the presence of fluid in the iliac fossa [3]. Focusing on the examination of bilateral adnexal areas, the presence or absence of masses and their location, the presence or absence of intact gestational sacs and their location in relation to the ovaries and fallopian tubes and uterus, the presence or absence of pelvic fluid or blood accumulation, abdominal fluid or blood accumulation, etc. Vaginal ultrasound, because it is not disturbed by intestinal cavity gas, fine gestational sacs, masses, primitive vascular pulsations can be shown early, with clear images, can detect embryonic pulsation signs with Doppler spectra earlier, improve the early detection rate, and provide Therefore, vaginal ultrasound is significantly better than abdominal ultrasound, so for ectopic pregnancy with atypical clinical symptoms, transvaginal ultrasound is recommended to be used as early as possible, and ultrasound examination should be repeated, with vaginal ultrasound as the main method and abdominal ultrasound as the supplement, and the combination of both methods can improve the early detection rate and emphasize dynamic observation [4]. Blood HCG and posterior vault aspiration were performed in close clinical integration. After diagnosis, conservative treatment and surgical treatment can greatly improve the maternal health rate and cure rate; greatly reduce the risk of maternal life and casualty rate.
