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

ObjectiveTo study the composition of intracavitary deposits on Essure® hysteroscopic sterilization devices.DesignCase report.SettingReproductive Medicine and Gynecology department of a University Hospital.PatientsA 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.InterventionDiagnostic hysteroscopy and surgical removal of Essure® devices was performed. The deposits were collected and infrared spectroscopy analysis was performed.Main outcome measureChemical composition of the deposits attached to the device.ResultsInfrared spectroscopy of the material showed patterns conclusive with calcite (calcium carbonate, CaCO3).ConclusionUntil now, it is not clear if there is a relationship between reported complaints and formation of calcite deposits on Essure®.CapsuleInfrared 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.
