Many women decide to have “permanent” sterilization as a birth control method when they feel they no longer want to have children. Often this takes the form of a tubal ligation in the woman or a vas deferens ligation (Vasectomy) in the man. Subsequently, some of these men and women change their minds and want to have the sterilization reversed. Happily, the surgical blockage can be removed in most cases of ligation in both men and women. This “reversal” will usually result in pregnancy as long as no other factor has occurred to prevent conception. In women, this is typically the case and pregnancy can be achieved, depending on the type of ligation originally performed, about 90% of the time.
Reanastomosis, or tubal reversal, is a procedure in which a woman, who has had a prior tubal ligation by rings, clips, or fulguration can “reverse’ the ligation to achieve pregnancy. Pregnancy rates with reanastomosis depend on several factors. The fallopian tubes have got to remain patent, or open. Additionally, the woman’s age and other factors that affect overall fertility are to be considered. More than 75% of women will be able to conceive following a successful reanastomosis.
In this process an incision is made into the abdomen to gain access to the fallopian tubes. The ends of the fallopian tubes are then incised to expose the opening of the tube or lumen. The tubes lumens are reattached under a microscope. As soon as the tubes are reattached, the serosa, or outer covering of the tubes are brought together over the top of the inner portion of the tube. Often, colored dye is used to test the repair and patency of the fallopian tube.
