Intracavitary deposits on Essure® hysteroscopic sterilization devices: A case report

Objective To study the composition of intracavitary deposits on Essure® hysteroscopic sterilization devices. Design Case report. Setting Reproductive Medicine and Gynecology department of a University Hospital. Patients A 39 years old patient presenting with a request for surgical removal of Essure® sterilization devices. Diagnostic hysteroscopy showed a crystal like white deposit attached to one of the devices. Intervention Diagnostic hysteroscopy and surgical removal of Essure® devices was performed. The deposits were collected and infrared spectroscopy analysis was performed. Main Outcome Measure Chemical composition of the deposits attached to the device. Results Infrared spectroscopy of the material showed patterns conclusive with calcite (calcium carbonate, CaCO3). Conclusion Until now, it is not clear if there is a relationship between reported complaints and formation of calcite deposits on Essure®. Capsule Infrared spectroscopy of deposits on Essure® devices showed a pattern conclusive with calcite. The relationship between reported complaints and the formation of calcite deposits on Essure® remains unclear.
