Due to the different physiological anatomy of males and females, the operation method of ligation reversal surgery may be different, but the operation principle is the same: the ligated fallopian tube or vas deferens is removed and reconstructed. Since various tests may be performed before the surgery and the surgery is more delicate, hospitalization is required for treatment. Compared with traditional open surgery, laparoscopic reversal is less painful, less bleeding, less likely to damage other organs, and more aesthetic. For those who require vasectomy after vasectomy for various reasons, the doctor will take an incision at the ligature site, find the vas deferens and free it, cut the ligature site and anastomose the severed vas deferens, or anastomose the distal vas deferens with the epididymis. Since the vas deferens is thin and the anastomosis is difficult, the procedure is usually performed under a microscope, which can improve the success rate to a certain extent. At present, due to the more and more perfect reproductive assisted technology in China, it is no longer the first choice to perform complex ligation reversal clinically, and the reversed fallopian tubes and vas deferens do not work satisfactorily, but increase the risk of tubal pregnancy, hydrocele and infection to some extent. Therefore, ligation reversal should be carefully chosen under the strict assessment of the physician.
