The hysteroscopic tubal cannulation is a procedure done to remove the blockage within the fallopian tubes using the hysteroscopy to treat the infertility in females. More than 10% of the infertility cases are diagnosed with the tubal blocks.
Fallopian tubes allows about 1/3rd of the embryo fertilization within the tubes and it also acts as the connecting tube between the ovaries to the uterus on either sides maintaining the normal functions of the reproductive system. When this tube gets blocked due to the adhesions, fetal mass, tubal ligations and mucus plugs, it emerges as the major infertility factor which has to be corrected by surgical methods.
This tubal block is usually diagnosed during the hysterosalphingography to elicit the causes of infertility in females. The dye injected sometimes even helps in pushing out the small adhesions during HSG, but the other tubal blocks to be removed by the hysteroscopic cannulation.
During this procedure the special catheter guided with the hysteroscope is inserted through the tubal ostium to reach the interstitial part of the tube from the vagina. When the tube reaches the exact location of the blockage, then the tubes are cleared using the balloon on the catheter. This method helps in removal of any proximal tubal obstruction causing infertility.
However there are also some contraindications for this procedure in females with salpingitis (inflammation of the fallopian tubes), history of tubal surgeries, genital tuberculosis, small tubes and obstruction in the distal end of the tubes. There are also some complications noted with this method like rupture of fallopian tubes, scarring of the tubes and the life threatening peritonitis disease.
