20% to 40% of female infertility is due to the inability to conceive because of tubal incompatibility. After excluding vulvar abnormalities, vaginal abnormalities, ovarian abnormalities, endocrine abnormalities, psychoneurological abnormalities, immunologic factors, systemic diseases and other infertility factors, it is necessary to perform a uterine tubal iodine oil angiography to diagnose uterine cavity and tubal lesions. Among them, the proportion of uterine cavity lesions is low, and most of them are tubal abnormalities. The general diagnosis of tubal anomalies is generally categorized according to their severity as: poorly communicated, poorly communicated, very poorly communicated, slightly communicated and basically pelvic. The first two of these cases are milder cases, through the drug anti-inflammatory treatment (including Western medicine or traditional Chinese medicine), the chances of pregnancy is quite large, as long as the active treatment, relaxation, reasonable time coitus, most of them can get pregnant. If the patient is still not pregnant after one year, selective tubal insertion (i.e. tubal intervention) can be performed. In the latter cases, such as pass but very poor, surgery is usually needed first, and then with medication, pregnancy is also possible. There are two main types of tubal surgery: selective tubal insertion and laparoscopic adhesion release. It is generally recognized that patients with poor to very poor patency should undergo selective tubal insertion, as well as patients with proximal tubal obstruction. Laparoscopic release of adhesions, on the other hand, is suitable for pelvic patients with slightly patent or impassable tubal umbilical adhesion packages and patients with distal tubal obstruction. In terms of success rate, cost, and time, elective tubal insertion should be performed first, except in patients with distal obstruction and umbilical adhesion wraps. Under the premise that the success rate is basically the same, the cost of the two procedures and other comparisons are as follows: 1, tubal insertion is about 2,000 yuan, laparoscopy is about 20,000 yuan; 2, tubal insertion does not require hospitalization, while laparoscopy requires hospitalization; 3, both pelvic inflammatory disease for intraoperative drug perfusion, but tubal insertion does not require intraperitoneal operation, only intrauterine operation. No anesthesia is required.
