Tubal ligation is the surgical procedure that is performed as a means of birth control in women. In this procedure, the fallopian tubes – the tubes that carry the eggs from the ovaries to the uterus – are either tied, clipped, burned or cut in order to sever this passage.
This is considered as a permanent method of birth control and should not be considered unless one is very certain about not giving birth to any more children. Tubal ligation can be performed by various methods – all of which prevent the meeting of the sperm and the egg. These methods are as follows:
Various Types Of Tubal Ligation For Birth Control
The Pomeroy Technique
This is the most commonly used and preferred method of tubal ligation. This is also the easiest method, and is used most commonly after a cesarean section. In this method of tubal ligation, the fallopian tube is raised up in the middle to form an inverted ‘U’. The two sides are brought together and tied together to form a loop with the help of a dissolvable ligature (thread or anything used to tie something tight).
The loop is then cut off, leaving two raw ends of the tube. Within a few days, cells begin to form within these two ends. The ligature dissolves and the two parts of the fallopian tube separate. The two ends cannot reattach themselves together on their own because of the new cells that have now formed inside the ends.
Tubal Rings Or Clips
This method is best used in case a reversal of the procedure is preempted; this is because there is the least amount of damage done to the fallopian tube via this method. Using a tubal ring is the same procedure as the Pomeroy technique except that a ring is used instead of a dissolvable ligature.
The damage occurs only to the loop whose blood supply is cut off by the ring. This eventually falls off and scar tissue takes its place. In the case of clips, damage of the fallopian tube takes place only where the clip is clipped on.
Tubal Ligation And Resection
In this method, a small part of the middle of the tube is ligated and then removed. A ligature is used to seal off the tube at two points on the fallopian tube. The middle portion is then cut off and removed. The ligatures eventually dissolve, leaving the fallopian tube in two parts.
Bipolar coagulation and monopolar coagulation are two laparoscopic procedures that are used for tubal ligation. Of these two procedures, greater damage is expected in the monopolar coagulation method.
In these methods, electric current is passed to a part of the fallopian tube until it is cauterized.
This method of tubal ligation is performed on the part of the fallopian tube that is closest to the ovary. The tips of the fallopian tube consist of long finger-like projections called fimbriae. These projections are very important because they help to grasp the egg and pass it into the fallopian tube. These fimbriae are gathered together, tied up and removed.
