Extended Application of Intraoperative Parathyroid Scores System(IPSS) in Thyroidectomy

Extended Application of Intraoperative Parathyroid Scores System(IPSS) in Thyroidectomy

after established the Intraoperative Parathyroid Scores System (IPSS) for thyroidectomy we further extented the clinical value of Intraoperative Parathyroid Scores System in Treatment decisions of calcium treatment time and improve recognition skills of parathyroid in Clinicians

IPSS includes transplantation Parathyroid Scores and in situ Parathyroid Scores, the investigators will establish the Intraoperative Parathyroid Scores System by parathyroid size and Blood supply, and recording IPSS, according to certain rules. We expand IPSS, including the description of the location of parathyroid after postoperative.Parathyroid hormone and calcium were test in d0, d1, d14, d60 post operation. The correlation between Intraoperative Parathyroid Scores and PTH calcium were calculated, and ROC curve and logistic regression were tested for the prediction value.and after that we further evaluate the relationship Between IPSS and calcium supplement time.and Whether IPSS enhance ability of parathyroid recognition for clinical doctors.

3. preoperative serum calcium, parathyroid hormone levels were normal;
4. intraoperative and postoperative clinical data integrity, standardized follow-up patients;
5. parathyroid is a tumor violation.

Exclusion Criteria:

1. serious underlying disease;
2. age greater than 60 years of age or combined with arteriosclerotic disease;
