The problem with mesh

The female pelvic floor is a group of muscles supporting the uterus, bladder, vagina and rectum. Around half of women who have had children will experience some kind of pelvic floor dysfunction, such as pelvic organ prolapse (POP) and stress urinary incontinence (SUI).

Historically, surgery for POP involved repairing the weakened connective tissue with sutures. To achieve lower rates of recurrence, surgeons and manufacturers decided that the surgical mesh already routinely used to treat abdominal hernias could be placed through the vagina to treat POP. Such implants were intended to be permanent.

Though there had been no clinical trials on living humans, the first mesh for this purpose, ProteGen, was approved by the US Food and Drug Administration (FDA) in 1996. It was recalled by the manufacturer in 1999 after too many women experienced serious complications. [1] By then the market was flooded with surgical mesh devices approved as ‘substantially equivalent’ to ProteGen. These were not recalled, and were aggressively marketed to surgeons and hospitals around the world.

By 2002 they were freely available in New Zealand, which had no requirements for pre-market testing or proof of safety or efficacy for medical devices. Surgeons recommended the procedure to patients, who received very little information about what the surgery involved. Research showed that very few, if any, were warned about the potential risk of lifelong complications. [2]

In 2008 a statement released by the FDA warned of risks from pelvic mesh, including erosion of vaginal tissues, pain, infection, recurrence of POP, and new onset of SUI. At that time New Zealand’s Medsafe had received only 14 reports of adverse events (such reports are not mandatory, and the Accident Compensation Corporation (ACC) did not share treatment injury information with Medsafe until 2017.) [3] After a review, Medsafe concluded that the benefits of using pelvic mesh outweighed the risks.

In 2011 the FDA, after evaluating adverse event reports and assessing the scientific literature, stated that it had not seen conclusive evidence that transvaginally placed mesh improved clinical outcomes any more than traditional POP repair, and that it ‘may expose patients to greater risk’. [4] However, New Zealand surgeons continued to offer mesh as a first-choice option, and were very slow to recognise that transvaginal mesh implants were causing severe complications. Patients reported that their experience of debilitating pain was dismissed – they received responses such as ‘it’s in your head’, ‘mesh can’t cause pain’, and, most frequently, ‘you are the only one that has this problem’. They were referred to pain clinics and psychiatrists.

In 2012, the first court case against a mesh manufacturer ended in favour of the woman. A gag order came off and media coverage began. [5] Affected women made the link between their pain and suffering and the mesh implant, and realised they were not alone. As Carmel Berry recalled: ‘The feeling of finally being believed was overwhelming. I wanted to talk to other women, share my story publicly and warn others to avoid mesh.’

The formation of Mesh Down Under

Mesh Down Under was initially conceived as an online support group for people to share their lived mesh experiences. From an initial group of six members, numbers grew to over 50 within a few months. Co-founders Carmel Berry, Patricia Sullivan and Charlotte Korte realised that the number of mesh-injured New Zealanders was increasing and that the issue needed to be highlighted to the health sector and lawmakers.

Over the following two years, calling themselves ‘The Three Meshketeers’, they researched the scale and scope of the issue, and endeavoured to highlight to health authorities the difficulties faced by these patients as they searched for recognition of their symptoms and the help they needed. They doggedly sought help from many organisations and people in the health sector, including Medsafe, Women’s Health Action, representatives of various medical colleges, the Health Quality and Safety Council, Health and Disability Commissioner (HDC), and ACC. Almost every meeting concluded with a recommendation that they contact another agency or organisation that ‘may be able to help’.

They also regularly wrote to politicians and ministers asking them to investigate the growing number of mesh-related treatment Injury claims. They established relationships with media contacts and got regular coverage from investigative journalists who were aware that the issue was now a global scandal. [6]

Taking action

The team obtained and collated various government documents using the Official Information Act, and conducted their own research within the growing Mesh Down Under community. By March 2014 they believed they had enough evidence to convince the government to launch a full inquiry into the problem. They launched a petition calling for the Health Select Committee to recommend an independent and transparent inquiry into the use of surgical mesh in New Zealand. Their supporting submission provided ‘overwhelming evidence about the use and issues of surgical mesh and [suggested] concrete ways to improve outcomes for patients’. [7]

After numerous gruelling sessions in which the women were challenged by top health officials, the Health Select Committee’s report was presented to Parliament on 1 June 2016. [8] It made seven recommendations in three areas: the investigation of options for a surgical registry, improvement in medical practice, and the role of the regulator in pre-market medical device approval. In a report tabled on 24 August 2016, the government supported all the committee’s recommendations. [9].

The founders of Mesh Down Under felt that progress was finally being made, yet the number of ACC claims continued to rise. This was made public by a full review published in 2015 and updated in 2018; more than a thousand New Zealanders had suffered mesh-related adverse events. [10]

A literature review published in 2016 concluded that mesh placed in the vagina for treatment of prolapse was not recommended. A Scottish clinical trial which Mesh Down Under had discussed at length with the select sommittee, published in January 2017, found that mesh implants for pelvic organ prolapse were not proven to be effective or safe.  [11]  

After much pressure from Mesh Down Under, on 11 December 2017 Medsafe used the provisions available under section 38 of the Medicines Act to contact four suppliers of surgical mesh implants used in urogynecological surgery, requesting information relating to the safety in use of products currently notified as being available in New Zealand. On 31 January 2018, Medsafe announced that all four companies had confirmed that transvaginal surgical mesh products for pelvic organ prolapse were no longer supplied in New Zealand. [12]

The Mesh Roundtable

While Mesh Down Under’s 800 members welcomed this outcome, the battle to address the continued use of surgical mesh for other health conditions, including stress urinary incontinence, resulting in ongoing ACC claims, remained to be fought. By 2018 the organisation was part of a government working group known as the ‘Mesh Roundtable’, chaired by the Ministry of Health, with representatives from three medical colleges, ACC, HDC, the Private Health Association, and Medsafe.

The Mesh Roundtable’s first completed project was the creation of a patient information document specific to female stress urinary incontinence procedures which use surgical mesh. This was designed to be provided to potential patients, to ensure that all the potential risks and complications of the procedure would be disclosed, so that the patient could feel they had made an informed decision before proceeding with this treatment option. It was due to be launched in mid-2019. The Mesh Roundtable was working on several other projects, all with the common objective of creating better patient outcomes – exactly what Mesh Down Under had aimed for with its 2014 petition.
