Medical errors have never been inevitable since ancient times, and in our country there is the “Medical Forest Correction” in ancient times, which shows that doctors’ misdiagnosis and efforts to correct errors have existed since ancient times. Adenomyosis is a gynecological disease that occurs mainly in women of childbearing age, and can cause greater harm, women often do not know much about this disease, the information provided to the doctor after the disease, the description is not clear, but also easy to cause misdiagnosis and other phenomena. So women should know about adenomyosis, especially its symptoms and other knowledge. Today, we will explain to you what adenomyosis is. Adenomyosis is a form of endometriosis. As we all know, women bleed once a month, we call it menstruation, what is it all about? That is to say, under the stimulation of endocrine secretion of ovaries, the endometrium thickens every day and in about one month, the endometrium is very thick. Under the influence of endocrine secretion, the endometrium is shed and discharged from the uterine cavity down the yin channel to form menstruation, but some endometrium is very naughty, it may run from the uterine cavity to the muscle layer of the uterus. The endometrium reaches the myometrium and when menstruation occurs, there is more and more blood in the myometrium, and when there is more and more blood, the uterus becomes bigger and harder. In this case, the clinical manifestation is an enlarged uterus, a hard uterus, and unbearable abdominal pain during menstruation. In addition, due to the heavy menstrual flow, it is easy to become anemic. A large proportion of patients with adenomyosis have varying degrees of anemia. After adenomyosis, the uterus is hard and large, married women may have infertility, or even miscarriage after pregnancy. When she came to me for a hysterectomy, she reported that she had pain in her lower right abdomen, which was so unbearable that she went to the local hospital and was treated for chronic appendicitis. Because some patients with adenomyosis feel pain in the right lower abdomen, and the main symptom of the appendix is also pain in the right lower abdomen, so finally the appendix was removed, but the final cause was still not found, and it still hurts. The general diagnosis of adenomyosis and appendicitis is not difficult, but there is still a misdiagnosis of about 20%. The reasons for misdiagnosis are not only the experience and technical problems of the doctor, but also mainly because some appendicitis presentations are atypical. Due to the abnormal position of the appendix, abdominal signs are not obvious and, in addition, there are individual patient factors. In the past, the diagnosis of adenomyosis was often misdiagnosed, but now the diagnosis rate has improved considerably. With the increasing number of women attending annual checkups, and with the increasing use of ultrasound, pulsed Doppler, color flow imaging, color power imaging, and color three-dimensional ultrasound imaging (color ultrasound) in recent years, physicians are finding more patients with adenomyosis at checkups and in the patients they see. The prevalence of adenomyosis is on the rise. About 20% of patients with adenomyosis are detected by routine physical examinations in the complete absence of any symptoms. There are many differences between appendicitis and adenomyosis, which can be problematic to diagnose, as patients themselves often do not feel the disease at the beginning and are unaware of it until they have a medical checkup. Therefore, women must develop the good habit of regular medical checkups.
