Aim: The purpose of this study is to determine the factors affecting the development of parathyroid surgery in our hospital. Material and Method: We investigated the age, sex, laboratory, imaging and histopathologic data about the patients who had undergone parathyroid surgery between 2000 and 2010. We evaluated the methods used in diagnosis, determination of surgical indications, surgical and anesthesia techniques and the follow up period. We determined the data that can play a role in the process of diagnosis and treatment of this disease. Results: Until 2005 there were important deficiencies about laboratory investigations and specialists for parathyroid surgery. These were resolved in 2006, except an experienced surgeon. There had been only 2 parathyroid operations until February 2010 (one in 2002 and the other in 2007). In 2008 there was a case with incidental parathyroid adenoma excision during a thyroidectomy. In 2009, with the inauguration of an experienced surgeon, the parathyroid surgeries gained momentum. After this date, there were 28 parathyroid surgeries in 22 months. Twenty two of the cases had primary hiperparathyroidism and 6 had secondary hiperparathyroidism. Twenty one (95,5%) of the 22 parathyroid adenomas underwent MIP Six patients with secondary hyperparathyroidism underwent total parathyroidectomy and parathyroid autotranspiantation. The success rate of the treatment was 100%. Conclusion: Parathyroid surgery is a team work. With an appropriate team, more than 90% of parathyroid adenomas can be treated by MIP.

Objective: In this study we evaluated the usefullness of Tc99msestamibi, a tumor agent, to detect malignancy for nodules reported as "SFM" and "ITFL". Methods: Thirteen of 24 cases, reported as "SFM" or "ITFL" by FNAB, underwent bilateral total thyroidectomy after imaging by Tc99msestamibi. Then, Tc99msestamibi imaging, FNAB and hystopathologic results were compared. Results: There were only one male and the mean age was 44,9±12,6 (29-77). We detected "SFM" in 10 (76,9%) cases, and "TFL" in 3 (23,1%) cases. By hystopathologic investigation 6 papillary, 1 follicular, 1 medullary, 4 benign cystic goiter and 1 lymhocytic thyroiditis detected. There was MIBI uptake in all cases with malignancy, except one with medullary thyroid cancer (6 papillary and one follicular cancer). MIBI uptake was detected also in one of four cases with benign cystic gioter and one case with lynphocytic goiter. The mean nodule diameter was 26,9±20,1 mm (23,6±6.87 mm in benign cases, 29,28±26,45 mm in malignant cases, p>0.05). Conclusion: The sensitivity, specifity, pozitive and negative predictive value of of Tc99msestamibi were 75% and 60%, 0,75 ve 0,60, respectively. As conclusion, to determine the usefulness of Tc99msestamibi for detecting malignancy in nodules reported as "SFM" or "ITFL" by FNAB, more studies with larger populations should be performed.
