What kind of doctor treats Ovarian Remnant Syndrome?
A gynecologist, a doctor who treats the female reproductive system, usually diagnoses and treats ovarian remnant syndrome. A gynecologic surgeon, a gynecologist with extra surgery training, often removes the leftover tissue. A direct primary care or concierge doctor can be a first stop for an evaluation and can refer you to a specialist when needed.
What is ovarian remnant syndrome?
Ovarian remnant syndrome, or ORS, can happen after both ovaries are taken out. A hysterectomy, which removes the uterus, may or may not be part of that surgery. In ORS, the surgery leaves behind some ovarian tissue. That leftover tissue can then cause pelvic pain or a pelvic mass.
ORS is a rare complication of this surgery. It is hard to say how often it happens.
Symptoms
Most women with ORS have chronic pelvic pain. This is pain that lasts or keeps coming back. It may also come in a cycle. Some also have a lump, called a mass, in the pelvis. Others have a pelvic mass and no symptoms at all.
These symptoms can have many causes, so ORS can be missed or found late.
Causes and who gets it
ORS usually happens when part of an ovary is unintentionally left behind during surgery. Some things make this more likely. These include endometriosis, pelvic inflammatory disease, many past surgeries, and pelvic adhesive disease.
In these cases the layout of the pelvis can change. This makes it harder for a surgeon to remove all the ovarian tissue. Even a small piece of ovarian tissue can respond to hormones. It can grow, form a fluid-filled sac, or bleed. This can cause pain in women who have not reached menopause. Problems can show up years later. One report described a woman whose remnant was found 30 years after surgery.
How doctors diagnose it
Doctors start with your surgery history and a pelvic exam. Imaging tests such as ultrasound, CT, or MRI can look for leftover tissue or a mass. Blood tests for the hormones FSH, LH, and estradiol may also help.
Doctors confirm the diagnosis when tissue removed in a later surgery is found to be ovarian tissue.
Treatment
The recommended treatment is surgery to remove the leftover tissue. Surgery can use one large cut in the belly (laparotomy) or small cuts and a camera (laparoscopy). Laparoscopy seems to be as safe as open surgery and to work as well.
In one group of 20 women, surgery done mostly through small cuts treated ORS safely and well. Surgery also lets doctors test the tissue for cancer. Cancer in remnant tissue is rare, but it did occur in 2 of those 20 women.
Hormone medicines, such as birth control pills, may be used to suppress ORS. This is for women at high risk from surgery. They do not replace a tissue diagnosis.
When to see a doctor
Tell your doctor if you have ongoing lower belly or pelvic pain after your ovaries were removed. A pelvic mass or pain that does not go away should be checked by a doctor. Cancer in remnant tissue is rare but can occur. Call 911 or go to the emergency room for severe belly pain or pressure, fainting, or bleeding that will not stop.
How a direct primary care or concierge doctor fits in
A direct primary care doctor charges a flat monthly fee instead of billing insurance, while a concierge doctor usually charges more and often works alongside insurance. Either kind of doctor can take your history, do a pelvic exam, order a first ultrasound, and refer you to a gynecologist.
Common questions
Can ovarian remnant syndrome happen if both ovaries were removed?
Yes, it can. It happens when some ovarian tissue is left behind after the surgery. It is rare.
Can ovarian remnant syndrome cause cancer?
Rarely, yes. In one group of 20 women treated for remnant tissue, 2 had cancer in that tissue. That is one reason doctors recommend removing the tissue.
How is ovarian remnant syndrome treated?
The usual treatment is surgery to remove the leftover tissue. Small-cut surgery with a camera is often used.
Can ovarian remnant syndrome show up years after surgery?
Yes, it can. One report described a woman whose ORS was found 30 years after her ovaries were removed.
