Mild Primary Hyperparathyroidism
Conditions
Brief summary
The aim of our study is to evaluate the value of the camera called "Fluobeam" in the localization, visualization of the parathyroid glands for patients with mild primary hyperparathyroidism.
Detailed description
Recently, it has been shown that parathyroid glands presented auto fluorescence, visible in the near infra-red light. Parathyroid glands emit at 822 nanometers when they are stimulated by a laser of 785 nanometers. Fluoptics Company (Fluoptics SAS, Grenoble, France) will provide a camera called "Fluobeam", facilitating the visualization of the parathyroid glands. The fluorescence intensity of the parathyroid glands is much more elevated than that of the surrounding tissues. Preliminary work showed the interest of this technique. Benmiloud and collabortors have shown that the utilization of the "Fluobeam" enable to decrease the post total thyroidectomy hypocalcemia rate by a better visualization and preservation of the parathyroid glands. The aim of this study is to evaluate the value of "Fluobeam" in the localization, visualization of the parathyroid glands for patients with mild primary hyperparathyroidism.

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| To compare the time required for the parathyroidectomy with or without the utilization of the camera "Fluobeam". | At Day 1(parathyroidectomy) |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| To compare the results of the parathyroidectomy with or without the utilization of the camera "Fluobeam" in term of biological recovery. | At 6 months post parathyroïdectomy | To compare the results of the parathyroidectomy with or without the utilization of the camera "Fluobeam" in term of biological recovery determined by normocalcemia (2,20 mmol/L \< calcium \< 2,60 mmol/L) at 6 months post surgery. |
| To compare the results of the surgery with or without the utilization of the "Fluobeam" in term of number of visualized parathyroid glands. | At Day 1(parathyroidectomy) | — |
| To compare the results of the surgery with or without the utilization of the "Fluobeam" in term of post-surgery laryngeal paralysis. | At 6 months post parathyroïdectomy | — |
| To compare the results of the surgery with or without the utilization of the "Fluobeam" in term of parathyroid morbidity (hypocalcemia with calcémia below 2 mmol/L) | At 6 months post parathyroïdectomy | — |
| To compare the results of the surgery with or without the utilization of the "Fluobeam" in term of cost-utility analysis according to the societal perspective and over a 6 months' time horizon of the surgery. | At 6 months post parathyroïdectomy | — |
