Arms of the Study

Arm 1

Arm 2

Arm Type

Experimental

No Intervention

Arm Label

Vitamin D

Fruit juice

Arm Description

During preoperative visit (Month -2) patients will receive a cholecalciferol supplementation added to a fruit juice.

During preoperative visit (Month -2) patients will receive only fruit juice.

Outcomes

Primary Outcome Measures

Assessment of the effect of pre-operative cholecalciferol supplementation on the occurrence of post-operative hypocalcemia after total thyroidectomy
Measure of the occurrence of serum and / or clinical hypocalcemia. Serum hypocalcemia is defined by a level of calcemia, corrected for albuminemia, of less than 2.00 mmol / L. Clinical hypocalcemia is defined by the appearance of one of the following signs: sign of Chvostek, sign of Trousseau, paresthesias of the extremities and perioral between surgery and day 15

Secondary Outcome Measures

Comparison of clinical course in both Arm
Clinical course will be measured, for several items, and compared between both groups to see if a significant difference is observed. Items, considered for comparison, are listed below : Initial hospital stay (number of days), number of readmission, adverse event (number)
Comparison of severity of hypocalcemia in both arm
The severity of hypocalcemia will be measured in both arm, to see if a significant difference is observed, with items listed below : Calcemia, corrected for albuminemia, of less than 1.90 mmol / L the use of calcium gluconate IV in the first 15 post-operative days) duration of hypocalcemia's symptoms in the first 15 days postoperative
Comparison of the effect of supplementation on vitamin D deficiency in both arm
Comparison between measured initial value of 25OHD at the inclusion visit to the measured value of 25OHD on the day of the operation in both groups.
Comparison of parathyroid activity in both arm
Parathyroid activity will be evaluated in both group by measuring parathormone (PTH). Hypoparathyroidism being defined by PTH < 15 ng / L.
Assessment of the prevalence of definitive hypocalcemia
Collect of the definitive hypocalcemia's numbers in each group
Assessment of the effect of vitamin D supplementation on the occurrence of hypocalcemia in risk groups: hyperthyroidism, cancer, dissection associated with thyroidectomy
Collect of the number of adverse events and serum calcium levels for each participant

5. Study Description

Brief Summary
This prospective study evalue the inflence of pre operative vit D3 administration on post operative hypocalcemia in patients undergoing Total thyroidectomy
Detailed Description
Thyroidectomy is a frequent procedure. This surgery is well known but not devoid of risks. The most common postoperative complication is transitory hypocalcemia. Some studies have reported that preoperative vitamin D deficiency (VDD) is a risk factor for hypocalcemia after total thyroidectomy (TT) in patients with non toxic multinodular goiter or graves's disease. Although the association between VVD and postoperative hypocalcemia in thyroid cancer patients undergoing TT plus central compartment neck dissection (CCND) remains unclear. This prospective study evalue the inflence of pre operative vit D3 administration on post operative hypocalcemia in patients undergoing TT.
