If you have had an endometrial ablation and have developed symptoms of pelvic pain you might have post endometrial ablation syndrome. It is a constellation of symptoms due to entrapped blood (hematometra) or tissue within a uterus that has previously undergone an endometrial ablation.
While relatively uncommon, it may be the most difficult to diagnose according to Dr. Suzanne Trupin of Women's Health Practice, as it may develop slowly, and need an ultrasound to diagnose.
Other complications of endometrial ablation include pregnancy, risks from recurrences of pre-existing conditions such as a polyp or fibroid, an infection of the uterus, or a pregnancy. If you have had a tubal ligation then it is possible that the condition could be post-ablation tubal sterilization syndrome.
The ablation procedure is designed to destroy all lining tissue, but in fact there is no way to confirm the completeness of the ablation at the time of the procedure. . It is thought that either residual or regrowth of the tissue is producing the symptoms of post-endometrial ablation syndrome.
Many women who do not have complete success in eliminating the lining tissue from the uterus may have some inadvertent consequences of the persistent menstrual bleeding on a cyclic basis. Remember the process of having an endometrial ablation does not change your hormones and the cycles persist as they were before. One source of the syndrome might be some pain due to the distention of the end of the fallopian tube that is closest to the wall of the uterus when it fills, or a part of the uterus fills with blood that cannot completely shed out as previously, thus producing these symptoms. Particularly if that tubal end is really a stump from a previous tubal ligation. In those cases small amounts of menstrual blood each month can accumulate in the tubal stump. Scarring and trapped blood or secretions in a pocket might cause the symptoms of post endometrial ablation syndrome. Other women might have a scaring of the internal structure of the uterus, for instance the cervix, preventing the outflow of what menstrual blood is produced monthly.The blood entrapped may become infected, and this could produce symptoms as well.
If you do have pain, first is to try to get an accurate diagnosis. Make sure there is no infection, or ovarian condition both of which can produce pelvic pain. Rare causes of the symptoms might be due to conditions such as tracks between the uterus and the bladder known as fistulas that have been seen after a woman has had prior c-sections and an endometrial ablation. Some gynecologists can tell based on examining the uterus with a device called a uterine sound that the scaring has occurred. Other signs of the scar tissue can be see on ultrasound.
Ultrasound done once, when you are not bleeding might miss cyclic hematometra, so you may want to do this again. MRI examinations may help diagnoses either hematometra (blood within the uterus) or adenomyosis (glands within the wall of the uterus). Once the diagnosis is made, then you and your gyno can establish a planned solution. For some women the solution is repeat ablation, for some the removal of the fallopian tubes, for others a hysterectomy, for some treatment with antibiotics.
