[Minimally invasive video-assisted parathyroidectomy (MIVAP) using primary hyperparathyroidism therapy (pHPT)]

Primary hyperparathyroidism (pHPT) is a general calcium, phosphate and bone metabolism malfunction due to increased secretion of the parathyroid hormone over a substantial period of time. Causal treatment is a surgical procedure - parathyroidectomy.

A retrospective study of patients who underwent surgery was conducted in the department of surgery at the Atlas Hospital in Zlín between 2005 and 2011. In this period, 2555 patients were operated on for thyroid and parathyroid gland disease. 182 of these patients (7.1%) had hyperparathyroidism. There were 80 standard parathyroidectomies, 82 MIVAPs and 20 MIRPs (minimally invasive radio-guided parathyroidectomy).

In the study, 82 patients were operated on using the MIVAP technique. 78 (95.1%) had a parathyroid adenoma, 2 (2.4%) had hyperplasia, 2 (2.4%) had a standard body. Using the MIVAP technique, 75 parathyroid gland adenomas were found in 72 patients, 3 patients (3.6%) had a double adenoma. Conversion was performed in 10 patients (12.2%). During standard revision, an adenoma was found intraparenchymatously in 4 cases (4.9%), in 2 cases the adenoma was removed during standard revision. There was no permanent NRL paresis. 4 patients (4.9%) experienced temporary NLR paresis, MIVAP was successful in 72 patients (87.8%), 6 adenomas were removed during conversion; currently, all these patients have normal levels of calcium and parathyroid hormone. No parathyroid gland adenoma was found in 2 patients (2.4%), nor was it removed using persistent pHPT. 2 patients (2.4%) with hyperplasia are being monitored for their borderline calcium and parathyroid hormone levels.

MIVAP is a complex endoscopic technique which can achieve 90% success rate in patients with the location of a parathyroid gland adenoma confirmed both by ultrasound and MIBI scanning.
