Despite many advances in minimally invasive tubal ligation surgery, it remains a more complicated procedure than vasectomy to achieve sterilization, the most common contraceptive option in the United States today.
The introduction of a transcervical method of sterilization through the use of the Essure procedure is changing that. We can now offer patients a quick, exceedingly safe, incisionless tubal occlusion procedure that has been found 99.8% effective at 3 years, and, in one report, 99.74% effective at 5 years of follow-up.
I am incorporating Essure into my practice, and have found it so useful that I have chosen to share it in this month's Master Class.
In general terms, Essure is a microinsert placed into the fallopian tube via a hysteroscopically guided catheter.
The microinsert consists of a flexible stainless-steel inner coil, a dynamic outer coil made of nickel titanium alloy (nitinol), and an innermost layer of polyethylene terephthalate (PET) fibers. These fibers gradually elicit a benign localized tissue ingrowth that occludes the tubal lumen.
A follow-up hysterosal-pingogram (HSG) 3 months post procedure confirms proper device placement and tubal occlusion.
The concept that led to the development of Essure tubal occlusion evolved from neurosurgery, in which coils have been used to block vessels. However, specialized coils had to be designed that would expand to the diameter and length of the fallopian tube.
