Tubal effusion is due to long-term chronic inflammatory infiltration of the fallopian tubes, which causes the shedding and necrotic cells to gather, before leading to blockage of the tubes and adhesion of the umbilical ends to form effusion changes; the endometrium of the fallopian tubes and the endometrium of the uterus are continuously connected, leading to chronic inflammation of the endometrium as well; this is also the main reason why many women do IVF during this period when the embryo does not easily get laid and fails; due to the presence of tubal effusion, blockage, and The tubal effusion contains a lot of inflammatory media, and these toxic materials easily reflux into the uterine cavity and erode the embryo so that it does not easily implant, during which the effusion tends to wash away the embryo, and many women have ectopic pregnancies. On balance, pretreatment of tubal effusion should be performed before doing IVF. The treatment options are: bilateral tubal resection, or proximal tubal ligation with distal stoma, i.e. tubal cisternostomy. The function of this procedure is to allow the fluid in the fallopian tubes to drain out of the body, thus avoiding its harmful effects. It is suitable for patients with proximal tubal patency and distal fluid collection or atresia. Of course, there are also physical therapy herbs and other methods, but clinical observation shows that patients with proximal tubal ligation and distal ostomy have the best results. Our center has many such patients with repeated failures who have been pretreated with hydrosalpinx and have had successful pregnancies!
