Search for: [Abstract = "Aims\: 1\). To evaluate diagnostic accuracy of intraoperative iPTH assay during minimally invasive parathyroidectomy with respect to few prognostic criteria most commonly used. 2\). To compare outcomes of video\-assisted minimally invasive parathyroidectomy \(MIVAP\) to open minimally invasive parathyroidectomy \(OMIP\). 3\). To assess indications for bilateral neck exploration in the era of minimally invasive parathyroidectomy, including short\-term outcomes of surgery with intraoperative iPTH monitoring added\-value.Material and methods\: Ad.1\). A retrospective study of 455 patients with sporadic primary hyperparathyroidism undergoing minimally invasive parathyroidectomy with intraoperative iPTH assay at our institution between 2003 and 2012 was undertaken. Diagnostic accuracy of few prognostic criteria most commonly used was done including Halle, Miami, Rome and Vienna criteria. Results of intraoperative iPTH assay were compared to outcomes of minimally invasive parathyroidectomy in 6\-months follow\-up after surgery \(serum calcium and iPTH levels\). Both ROC \(Receiver Operating, Characteristics\) curve and error matrix analysis were used for accuracy assessment of intraoperative iPTH assay prognostic criteria. Based on this method the following accuracy parameters were calculated for each intraoperative iPTH assay criterion separately\: sensitivity, specificity, positive predictive value \(P"]
