Surgical Mesh Implants

Medsafe continues to monitor adverse event reports relating to the use of surgical mesh implants for the treatment of pelvic organ prolapse, stress incontinence and/or hernia repair. Some medical device regulators have raised concerns about such mesh implanted transvaginally to treat certain conditions. Medsafe has investigated surgical mesh and concluded that it is safe when used in accordance with the manufacturers' instructions by an appropriately trained surgeon. This conclusion is in line with that of other device regulators and professional bodies. Medsafe notes that surgical mesh remains approved for use by medical device regulators globally.

What is surgical mesh?

Surgical mesh is a medical device that is used when repairing weakened structures with the aim of providing additional support. It can be absorbable or non-absorbable. Non-absorbable mesh will remain in the body indefinitely so should be considered a permanent implant.

Surgical mesh is in use for uro-gynaecological surgery including repair of pelvic organ prolapse and stress urinary incontinence. Surgery is used to treat pelvic organ prolapse when other non-invasive treatments have been found to be not suitable or have failed. The use of mesh in surgery was introduced in response to the high failure rate of both initial surgery and revision surgery estimated at about 30%1, with the aim of augmenting the surgery and reducing the failure rate.

Surgical mesh is also widely used for hernia repair. The most common hernia corrective procedure in the US relates to inguinal (inner groin) repair amounting to 800,000 cases out of a total of one million annually. By 2000, more than 90% of all groin hernia repairs in the US utilised surgical mesh.

Medsafe advice to clinicians

In September 2015, Medsafe wrote to all Chief Executive Officers of District Health Boards and private surgical hospitals to advise them of the latest information available at that time about the use of surgical mesh, particularly for urogynaecological applications.  A copy of this letter was also sent to the Royal Australia and New Zealand College of Obstetricians and Gynaecologists (RANZCOG) and the Urological Society of Australia and New Zealand (USANZ)

The key issues were clinicians should:

Medsafe Investigation 2008

In 2008, a review of reports of adverse events relating to urogynaecological surgical mesh implants was conducted by Medsafe. This investigation included a literature review of papers published on this subject.

The report was submitted to the Medical Device Incident Review Committee, an Australian advisory committee with representatives from several Professional Colleges, for review along with a report on the same subject from the Therapeutic Goods Administration Medical Device Incident Review and Investigation System. The committee concluded that the return of symptoms and erosion (into the vagina or rectum) were the most common problems associated with these devices and that there was a need to explain this to the patient in terms of the success rate they could expect. It also noted that training of surgeons was important to the success of this new type of surgery.

Information from other Medical Device Regulators

Several medical device regulators have published information about urogynaecological surgical mesh implants on their websites. No recall actions have been undertaken and the regulators conclude that the risks of complications are minimised when the product is used by surgeons who have had suitable training.

Medsafe surgical mesh implant events report

All adverse event reports relating to the use of surgical mesh implants received by Medsafe are recorded in the Medsafe post-market investigations database, reviewed and included in ongoing monitoring.

A summary table of events reported to Medsafe is available for download below. This information will be updated on a quarterly basis.

Note: This table includes only adverse events reported following the implantation of the mesh device in patients.
