    abstract = "INTRODUCTION: Bilateral neck exploration (BNE) has been the gold standard for the treatment of primary hyperparathyroidism (PHPT). Minimally invasive parathyroidectomy (MIP) has emerged as an alternative procedure for localised solitary adenomas. The most popular MIP techniques are the open MIP (OMIP) and the minimally invasive video-assisted parathyroidectomy (MIVAP). This study aims to assess whether we achieved a smooth transition from OMIP to MIVAP without compromising the results or increasing the cost. METHODS: A parathyroid adenoma was successfully localised preoperatively in 77/86 patients with PHPT. MIP was contraindicated in 27/86 cases. For MIVAP, a 5mm, 30 degree camera was employed, along with special instruments. RESULTS: Median preoperative parathyroid hormone (PTH) level was 145.9pg/dl (59-2,151) and median calcium (Ca) was 10.8mg/dl (9.3-19). Comparing MIVAP (N=31) with OMIP (N=28), there was no significant difference in the age, sex, location of the adenoma, preoperative PTH and Ca levels as well as in all the other factors compared, apart from the size of adenomas, which were bigger in the OMIP group (1.85cm vs 1.4cm, p=0.032). Moreover, cure rates, operating time, hospital stay and rates of postoperative normocalcaemia were similar between the two groups. CONCLUSIONS: Despite the learning curve, MIVAP was not found to be inferior to OMIP for localised adenomas. The final cost was no higher for MIVAP than OMIP with the use of common reusable instruments. This, along with surgeons' experience in parathyroid and endoscopic surgery facilitates a smooth and cost-effective transition from OMIP to MIVAP."
