Subject: Update - Use of Electric Morcellators during Laparoscopic Hysterectomy and Uterine Myomectomy
On May 7, 2014, Health Canada issued a Notice to Hospitals about the use of laparoscopic electric morcellators during hysterectomy and myomectomy for presumed benign uterine fibroids.Footnote 1 The Notice stated that the use of these devices, which allows for a minimally invasive surgical approach, may result in the spread and upstaging of occult uterine cancer, which cannot be reliably detected preoperatively. The frequency of unsuspected uterine cancer in women undergoing surgery for the removal of presumed benign fibroids has now been estimated to be in the range of 1-in-350, which is more prevalent than previously reported.Footnote 2
Health Canada has reviewed the relevant clinical and scientific data pertaining to this medical safety issue. Based on the results of its review, Health Canada will be working with device manufacturers to revise the instructions for use of laparoscopic electric morcellators.
Health Canada is requesting manufacturers to include the following warnings in the labelling of electric morcellators:
- Uterine tissue may contain unsuspected cancer. The use of laparoscopic electric 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.
Laparoscopic electric morcellators are contraindicated:
- for the removal of uterine tissue containing suspected fibroids in patients who are (i) peri- or post-menopausal, or (ii) candidates for en bloc tissue removal, for example, through the vagina or via a mini-laparotomy incision.
- in gynecologic surgery in which the tissue to be morcellated is known or suspected to be cancerous.
- The risks and benefits of using tissue extraction bags to contain tissue released during laparoscopic electric morcellation procedures remain to be determined.
Managing marketed health product-related adverse incidents depends on health care professionals and consumers reporting them. Reporting rates determined on the basis of spontaneously reported post-marketing adverse incidents are generally presumed to underestimate the risks associated with health product treatments. Any cases of serious or unexpected adverse incidents suspected of being associated with the use laparoscopic electric morcellators should be reported to Health Canada at the following address:
Any suspected adverse incident can be reported to:
Health Products and Food Branch Inspectorate
Address Locator: 2003D
Ottawa, Ontario K1A 0K9
Telephone: The Inspectorate Hotline: 1-800-267-9675
