FDA Issues Black Box Warning for Laparascopic Power Morecellators

Los Angeles, CAThe Food and Drug Administration (FDA) has issued a black box warning against using laparoscopic power morcellators in the removal of the uterus (hysterectomy) or fibroids (myomectomy) in the vast majority of women. In their statement, the agency explains that it has put the recommendation into immediate effect, and is also recommending that manufacturers of laparoscopic power morcellators include in their product labeling specific safety statements in the form of a boxed warning and two contraindications.

The boxed warning informs health care providers and patients that:

Uterine tissue may contain unsuspected cancer. The use of laparoscopic power morcellators during fibroid surgery may spread cancer and decrease the long-term survival of patients. This information should be shared with patients when considering surgery with the use of these devices.

The two contraindications advise of the following:

1. Laparoscopic power morcellators are contraindicated (should not be used) for removal of uterine tissue containing suspected fibroids in patients who are: peri- or post-menopausal, or candidates for en bloc tissue removal (removing tissue intact) through the vagina or mini-laparotomy incision. (These groups of women represent the majority of women with fibroids who undergo hysterectomy and myomectomy.)

2. Laparoscopic power morcellators are contraindicated (should not be used) in gynecologic surgery in which the tissue to be morcellated is known or suspected to be cancerous.

The FDA estimates that 1 in 350 women undergoing hysterectomy or myomectomy for the treatment of fibroids is found to have an unsuspected uterine sarcoma, a type of uterine cancer that includes leiomyosarcoma. If laparoscopic power morcellation is performed in women with unsuspected uterine sarcoma, there is a risk that the procedure will spread the cancerous tissue within the abdomen and pelvis, significantly worsening the patient’s likelihood of long-term survival. For this reason, and because there is no reliable method for predicting whether a woman with fibroids may have a uterine sarcoma, the FDA discourages the use of laparoscopic power morcellation during hysterectomy or myomectomy for uterine fibroids.

Laparoscopic power morcellators are medical devices used during different types of laparoscopic (minimally invasive) surgeries. These can include certain procedures to treat uterine fibroids, such as removing the uterus (hysterectomy) or removing the uterine fibroids (myomectomy). Morcellation refers to the division of tissue into smaller pieces or fragments and is often used during laparoscopic surgeries to facilitate the removal of tissue through small incision sites.
