The prevalence of infertility is increasing, and the results of a survey of infertility couples using standardized diagnosis organized by the World Health Organization in 33 centers in 25 countries in the late 1980s showed that about 5-8% of couples in developed countries are affected by infertility, and the prevalence of infertility in some areas of developing countries can be as high as 30%, and the prevalence of infertility in China accounts for about 12.5% of the population of childbearing age -15%. The incidence of infertility is increasing year by year, and according to the World Health Organization, infertility will become the third most common disease in the 21st century after tumors and cardiovascular diseases. The tubal disease is one of the main causes of infertility, and at present there is no standardized, unified and effective method for the examination and treatment of tubal disease, which often causes unnecessary mental, energy and economic losses to patients and aggravates the infertility condition, even leading to serious complications. I. Etiology 1. tubal dysplasia or agenesis, tubal tumors are rare. 2. Tubal endometriosis or tubal polyps. 3. Inflammation of the fallopian tubes is the most common. Long-term untreated vaginitis, cervicitis and endometritis leading to inflammation of the fallopian tubes can cause destruction of the fallopian tube mucosa, forming scarring and adhesions, and the tubal lumen can become narrowed or blocked. The cause of tubal inflammation is caused by pathogenic infections, mainly caused by staphylococcus, streptococcus, Escherichia coli, gonococcus, Aspergillus, pneumococcus, and chlamydia. Early inflammation only causes temporary obstruction of the fallopian tube mucosa due to congestion and edema, and active and standardized anti-inflammatory treatment can restore the structure and function of the fallopian tube to normal. If treatment is not timely, abscesses may form and destroy the structure of the fallopian tubes. The wall of the fallopian tube is thickened and stiffened by the transient inflammation, and adhesions are caused by this obsolete tubal inflammation. Because the inflammation has become a thing of the past, and tubal incompetence is a sequel to the previous one-off inflammation. The other type is tuberculous tubal infection, mostly due to the spread of tuberculosis and peritoneal tuberculosis. This inflammation often destroys the endometrium and the mucosa of the fallopian tubes, leading to permanent infertility. Clinical manifestations There are no obvious clinical symptoms of tubal blockage, mainly manifesting as infertility, which is often detected during tubal examination. Some patients with tubal obstruction may experience pain on one or both sides of the lower abdomen, cramping, discharge, back pain, increased blood volume during menstruation, dysmenorrhea, etc. 1.B ultrasound tubal lavage: lavage is a kind of blind test, which totally depends on the doctor’s personal operation and experience to check and judge the condition of the fallopian tubes, so it can be imagined that the accuracy rate of lavage test is not high. 2.Fallopian tube imaging: imaging can be performed by digital X-ray machine, so that both the doctor and the patient can clearly see the site and nature of the blockage, so the accuracy rate is high, up to 98% as reported in the literature. It is currently the most common test used to find out whether the tubes are patent and the degree of patenting and the specific site of blockage. If repeatedly performed, it can lead to tubal inflammation and other conditions. 3. laparoscopic tubal lavage: it is the gold standard for diagnosing whether the fallopian tubes are patent or not, and is used sparingly because laparoscopic tubal lavage requires hospitalization for about a week, requires anesthesia and costs 5-6 thousand dollars. It is only used for those with unexplained infertility that has not worked after repeated treatment, or those with tubal adhesions and hydrocele. Treatment: mainly the treatment of the sequelae of tubal inflammation 1, Chinese medicine: Chinese medicine dialectical treatment of tubal obstruction and adhesions has certain efficacy; together with acupuncture and physiotherapy, the effect is better. 2.Proximal tubal obstruction: Generally, if the obstruction is less than 3 cm from the tubal-uterine junction, wire intervention is available, but there is a possibility of re-infarction after treatment, and the obstruction time varies from 3 to 12 months (our data); our data statistics, the pregnancy rate after wire intervention is less than 10%, personal opinion: we do not advocate easily choosing wire treatment. 3. Distal tubal adhesions and hydrocele: laparoscopic treatment (also known as minimally invasive treatment). The treatment effect is sure and the pregnancy rate is reported to be up to 50%, but this procedure requires skilled lumpectomy and doctors with rich experience in reproductive physiology to achieve satisfactory results, so lumpectomy should be chosen with caution.
