Normal fallopian tube is about 8 ~ 10cm from the uterine end to the umbrella length, and the tube diameter ranges from the thinnest one to10 cm. Because the ligation operation will first use silk thread to ligate the fallopian tube, and then use electrocautery to destroy the inner diameter to stop bleeding, or even completely remove the entire fallopian tube. Therefore, whether the fallopian tube can be recanalized after ligation depends on the size of the surgical scope.

When doing tubal ligation and recanalization surgery, the doctor cuts off the fallopian tubes at both ends of the ligation site, aligns the internal tubes on both sides, and sews 4 to 8 stitches with extremely thin suture. In addition, the location of tubal ligation, the degree of edema damage, the diameter of both ends of fallopian tube, the remaining length of fallopian tube and the microsurgical operation ability of the operator are the main factors affecting the success of the operation.

1. It is required to try pregnancy three months after operation to prevent X-ray irradiation from affecting egg quality. However, because the real exposure time of fallopian tube interventional recanalization under X-ray is only about 2 minutes, according to clinical observation, pregnancy in the first month after operation will not increase the abortion rate and deformity rate of fetus.

2. At that time, the operation techniques and skills of interventional recanalization were the key to the success of recanalization and how to restore the function after operation. Consolidating treatment after operation will only increase the infection of patients, reduce the chances of pregnancy and increase their economic burden. After interventional therapy, except for short-term use of antibiotics to prevent infection, there is no need to treat fallopian tubes with drugs.
