    Primary Hyperparathyroidism - Strategy for Multigland Disease in the Era of SPECT-CT

    Acta Endo (Buc) 2017 13(1): 1-6 doi: 10.4183/aeb.2017.1

    Purpose. To re-examine our clinical practice and review strategy for treatment of primary hyperparathyroidism in patients with multigland disease. Methods. Retrospective analysis of 121 consecutive primary hyperparathyroidism (PHPT) patients who underwent surgery in a tertiary center between January 2010 and December 2014. Results. Of 121 patients with PHPT 87% had single gland adenoma (SGD) and 13% had multigland disease (MGD). The overall cure rate was 95.86%. MGD was more frequent in younger persons (<40y)(50% vs. 13.2%). All patients had SPECT-CT (Single Proton Emission Computerized Tomography) with 28% being SPECT-CT negative. Patients with MGD had a higher rate of persistent disease (13.33% vs. 2.83%). Specimen weight was <600mg in 75% of MGD patients. 67% of SPECT-CT negative patients had mild hypercalcemia (Calcium <2.75 mmol/L) which was more frequent in MGD patients (43% vs. 19%). Conclusions. MGD patients were more likely SPECT-CT negative (40% vs. 25.4%) and benefit from bilateral neck exploration (BNE) (74%). However, most SPECT-CT negative patients still have a single adenoma. In our series MGD was more frequent in younger patients, more likely SPECT-CT negative, often associated with mild hypercalcemia and had a higher persistence rate than SGD. BNE is the operation of choice in young, SPECT-CT negative patients. If ultrasound parathyroids suggests a single large adenoma, minimally invasive parathyroidectomy with intraoperative PTH monitoring can be considered.

    Retrosternal Goitres: A Practical Classification

    Acta Endo (Buc) 2017 13(3): 261-265 doi: 10.4183/aeb.2017.261

    Background. There is no standard definition for goitres extending below the thoracic inlet and no clear guidelines for pre-operative planning of surgery. The aim of this study is a practical classification of retrosternal goitres (RSG) based on the anatomical , radiological shape and size of the thyroid. Methods. Retrospective analysis of all thyroidectomies performed in a referral centre between January 2012 and December 2016. Patients with RSGs had a pre-operative CT scan of neck/thorax. Imaging was reviewed to establish features to predict the difficulty of delivering the goitre through the neck incision and to advise the best surgical approach. Results. 847 thyroidectomies were performed with n=98 involving RSGs. TypeA (n=47) are RSG with a shape of a “cone” or pyramid with the apex pointing down. Cervicotomy is the usual approach. TypeB (n=39) are goitres with a shape of a “pyramid’ with the apex pointing up, cervicotomy with ± manubriotomy or sternotomy ± thoracotomy maybe required. TypeC (n=6) are thyroid enlargements in the mediastinum connected by a pedicle with the thyroid in the neck. A cervical approach ± manubriotomy or sternotomy ± thoracotomy is needed. TypeD (n=6) are true intrathoracic or “forgotten” goitres. Sternotomy is indicated for thyroids in the anterior mediastinum though a thoracic approach for those located in the posterior mediastinum might be needed. Conclusion. The shape and size of goitres is important in carefully planning surgery. CT imaging with cross-sectional reconstruction should be analysed before operation. The proposed classification helps treatment planning and allows comparison of outcomes by anatomical complexity.

    A Comparative Analysis of the Initial East European Center Experience with a Western High-volume Center for Open Minimally Invasive Parathyroidectomy (OMIP) as Treatment of Primary Hyperparathyroidism

    Acta Endo (Buc) 2016 12(3): 297-302 doi: 10.4183/aeb.2016.297

    Objective. To compare results of treatment of primary hyperparathyroidism (PHPT) in two teaching hospitals (eastern and western Europe) and to establish conclusions regarding quality of surgery for PHPT in Romania. Methods. We reviewed two prospectively collected databases of patients submitted to open minimally invasive parathyroidectomy (OMIP) for symptomatic PHPT in two centers from Romania and the United Kingdom (UK). We included patients with biochemically proven PHPT and positive pre-operative localization studies. We excluded patients with negative localization studies, suspected multiglandular disease, concomitant thyroid disorders and chronic renal failure. Results. 60 patients were included, 27 in group A (Romanian cohort) and 33 in group B (UK cohort). We noted significant differences between groups in pre-operative serum calcium and phosphorus levels (p<0.5). There were no differences between groups regarding the presence of symptoms; in group A we had significantly more patients with renal calculi history (p=0.02), digestive symptoms (p=0.006) and osteitis fibrosa cystica (p=0.01). Two patients from the UK group had lithium associated hyperparathyroidism and 2 patients had genetic disease. Intraoperative parathyroid hormone measurement (ioPTH) was available only for group B and frozen sections were selectively used in both groups. Both the adenoma size and weights were significantly higher in group A. The median operative time was significantly longer in Romanian group (p=0.001); in this group we noted the single conversion to traditional cervicotomy (3.7%) from all studied patients. In group A we noted two patients (7.4%) with failed parathyroidectomy and persistent PHPT; the cure rate was 92.5% for Romanian group and 97% for the UK group. Conclusions. OMIP can be performed safe with a high cure rate in “small” volume endocrine centres with results comparable to western experienced endocrine centres. Romanian patients presented with more severe PHPT with more frequent end-organ damage, due probably to late diagnosis.
