Abstract
CONTEXT: Minimally invasive parathyroidectomy (MIP) procedure has become a widely accepted alternative to the standard four-gland exploration nowadays. OBJECTIVE: The aim of this study was to evaluate patients with primary hyperparathyroidism (PHPT), who had been treated with thyroidectomy and bilateral neck exploration (BNE), rather than MIP alone, due to coexisting thyroid nodules and to determine the benefits of simultaneous thyroidectomy and the possible negative outcomes of not performing this additional procedure. DESIGN: There were 185 patients who were operated for PHPT at our clinic from January 2014 to November 2016. SUBJECTS AND METHODS: 50 patients meet inclusion criteria: have thyroidectomy at the same time of parathyroid surgery, have concordant findings of parathyroid adenoma localization at preoperative MIBI-SPECT and the cervical US and have not had malignancy on fine needle aspiration biopsy (FNAB). RESULTS: The mean age of the patients was 55.3±10.4, and female to male ratio was 7:1. All patients had parathyroidectomy with BNE and thyroidectomy: 11 (22%) patients had micropapillary thyroid cancer (mPTC), 2 (4%) had papillary thyroid cancer (PTC). CONCLUSION: The results were inconclusive in clearly demonstrating which patients presenting with coexisted thyroid nodules should undergo thyroidectomy, rather than MIP, and which should be monitored for thyroid nodules after MIP. However, we consider that in cases who are not clearly indicated for thyroidectomy, MIP followed by monitoring of thyroid nodules can be the treatment approach.
