The PIP mammary prosthesis: a product recall study

Area of Science:

• Plastic Surgery
• Biomaterials Science
• Medical Device Safety

Background:

• Concerns regarding Poly Implant Prothèse (PIP) silicone breast implant durability preceded their 2010 market withdrawal.
• Speculation involved implant elastomer, filler gel, device safety, longevity, and a potential link to anaplastic large cell lymphoma (ALCL).
• Limited data existed to guide patients and clinicians regarding PIP implants.

Purpose of the Study:

• To assess the long-term outcomes and rupture rates of Poly Implant Prothèse (PIP) breast implants.
• To provide data to inform patients and healthcare professionals about PIP implant performance.
• To conduct an independent product recall study in aesthetic breast surgery.

Main Methods:

• A database of 453 patients who received PIP mammary prostheses between 2000 and 2005 was compiled.
• Patients were contacted for consultations and offered ultrasound scans (USS) to assess implant integrity.
• Key outcome measures included secondary surgery rates, implant rupture rate, and time to rupture.

Main Results:

• The overall patient rupture rate for PIP implants was determined to be between 15.9% and 33.8%.
• Implant longevity was observed to decrease with each successive year from 2000.
• No cases of anaplastic large cell lymphoma (ALCL) were diagnosed in the studied cohort.

Conclusions:

• Long-term studies on medical devices are essential for providing reliable information and supporting professional standards.
• This study provides initial, hard data on PIP implant performance, addressing a critical information gap for affected women.
• The findings represent the early results of what may be a widespread issue affecting numerous women with PIP implants in the UK.
