Brief summary

A prospective database of consecutive patients with hyperparathyroidism subject to surgery is created. Preoperative workup and operative findings are recorded in this registry to allow comprehensive analysis.

Detailed description

This is a non-interventional, prospective, monocentric, non-randomized trial. All patients with biochemically confirmed Primary Hyperparathyroidism (PHPT) who are scheduled for elective parathyroidectomy in the Endocrine and Digestive Surgery Unit of the University Hospital of Strasbourg are considered. Data concerning the age, the operative date, the results of the pre-operative biological work-up (plasma calcium, phosphor, parathyroid hormone (PTH) level, vitamin D), the results of pre-operative imaging (CT (computerized tomography) scan, 99mTc SestaMIBI Scan, 3D-Vitual Neck Exploration (VNE)), the operative data (the surgical approach, the localization and the dimensions of the adenoma (s), the necessity to convert to classical approach and its reason, the values of the intra operative PTH), the pathology results, the biological work-up at follow-up (plasma calcium, phosphor, PTH, vitamin D) are prospectively recorded in the database.

Interventions

DIAGNOSTIC_TEST3D-VNE (virtual neck exploration)

The 3D-VNE model is obtained with VP Planning software (Visible Patient, Strasbourg, France), using DICOM (Digital Imaging and Communications in Medicine) images of contrasted Computed Tomography scan of the neck in operative positioning.
