What is Fibroid Expulsion?
Alicia Armeli

Over the past three decades, uterine fibroid embolization (UFE) has become a popular treatment option for women with symptomatic uterine fibroids who want to avoid hysterectomy. Considered safe and effective, UFE has a long-term success rate of around 90%. 1

UFE treats fibroids by blocking the blood that flows to them, resulting in these noncancerous tumors gradually shrinking, thereby easing symptoms. For some women, fibroid expulsion—or the fibroid tumor detaching from the uterus and passing from the body—is an unusual occurrence post-UFE. According to a study published in the Journal of Vascular and Interventional Radiology, fibroid expulsion happens in almost 5% of women.2

“Fibroid expulsion can happen weeks to years after the procedure,” explains Richard Shlansky-Goldberg, MD, Interventional Radiologist and Professor of Radiology, Obstetrics & Gynecology, and Surgery at the Hospital of the University of Pennsylvania in Philadelphia, Pa., and lead researcher of the study. “Fibroid expulsion can lead to a lot of volume loss. For example, some patients who have only a single fibroid may end up being fibroid-free.”

The retrospective study included 759 women who underwent UFE between July 1999 and June 2009.2 Of these women, 37 (4.9%) experienced fibroid expulsion within an average of about 3 ½ months. Five percent of these women didn’t experience any symptoms, whereas 95% of the cases were symptomatic. The researchers found that the majority of women who experienced symptoms of fibroid expulsion (89%) had “bulk expulsion” or the passing of large pieces or entire fibroid tumors. The remaining (11%) had “sloughing expulsion,” which refers to the gradual shedding or dissolving of the fibroid tumor that then passes from the body as vaginal discharge.

“Fibroids that have a higher likelihood of expulsion include pedunculated fibroids, which are those located inside the uterine cavity and are attached to the uterine wall by a stalk,” Dr. Shlansky-Goldberg says. “This also includes submucosal fibroids or those just underneath the uterine lining and transmural fibroids or those that extend through the uterine wall to the outside of the uterus.”

Women may be able to pass fibroid tissue completely on their own. In other cases, gynecological help to remove partially expulsed fibroids is necessary. Shlansky-Goldberg and his team found that 49% of fibroid expulsion cases happened at home or during an office/emergency room transvaginal myomectomy (TVM)—a type of minimally invasive removal of fibroids through the vaginal canal.2 Twenty-seven percent needed operative TVM and 8% had hysteroscopic fibroid resection—a procedure that places a scope inside the uterus and navigates fibroid removal through the scope.2

If fibroid tissue doesn’t fully pass from the body and can’t be surgically removed through the vagina, there’s a risk of infection. This can happen if the fibroid tissue doesn’t detach enough from the uterus to be expulsed or a woman’s cervix may not dilate enough to allow the tissue to pass. This can lead to the need for a hysterectomy—the surgical removal of the uterus—but is a relatively rare complication. Women who have given birth tend to do better with expelling the fibroid than women who haven’t given birth.1

In this study, urgent hysterectomy occurred in only 11% or only 4 women of the 37 who experienced expulsion. Even fewer women, 4% or 2 women, experiencing fibroid expulsion chose hysterectomy for reasons such as bothersome chronic vaginal discharge.2

But for the majority, discharge and mild cramping only lasts a few weeks to months, according to Dr. Shlansky-Goldberg. “Most women are happy that the fibroid is out. After it’s done, many patients will see a dramatic reduction in the size of their uterus with some uteri becoming a normal size without fibroids,” he continues. “My first patient who experienced expulsion hugged me afterward because—by losing the bulk of the fibroid—she was able to fit into jeans that she was unable to fit into for the last several years.”

Uterine fibroids affect up to 80% of women by age 50 and can have severe symptoms like heavy periods, pelvic pain, and infertility.3 UFE is one of the treatment options available. But since no two women’s fibroid experiences are the same, Dr. Shlansky-Goldberg encourages collaboration of care between interventional radiologists and gynecologists—especially when patients have a higher likelihood or already experienced fibroid expulsion.

“Our protocol is for patients to first contact their interventional radiologist so an MRI can be done and a diagnosis of fibroid expulsion can be made,” he says. “With this information, an interventional radiologist can together formulate a plan with the patient’s gynecologist to ensure that the best care is given to the patient.”
