One method requires the usage of a tubal cannulator, which is introduced into the uterus via the cervix, providing the fallopian to be reattached with a fine stent. This provides for improved alignment of the tubes, so a much better connection can be established. Little sutures (less than a hair in thickness) are cautiously and meticulously set to connect the 2 sections.Once the joining (anastomosis) is complete, a blue contrast material is injected via the uterine cervix, traveling through the uterus and fallopian tubes, all the way to the abdominal cavity. This is done to ensure that the tubal ligation reversal have been joined in good order and that the joining is working well.
