Preoperative localisation of pathological glands in patients with primary hyperparathyroidism (PHP) is the mainstay for mini-invasive parathyroidectomy.

The aim of this study was to assess if a mini-invasive approach is feasible in this kind of patients. In this retrospective study were included patients that underwent parathyroidectomy for PHP. Patients were divided into two groups according to concordance of US and MIBI scan results. 242 patients were included: 183 had concordant preoperative studies, and 59 had discordant or negative studies. A mini-invasive approach was possible in 42 (72.9%) patients with unclear preoperative studies, whereas 12 (20.3%) additional patients required conversion to BNE.

In patients with unclear preoperative studies, a negative result of intraoperative PTH allowed to avoid a persistent disease in 12 patients, while in 3 cases led to an unnecessary additional exploration. In patients with discordant preoperative studies a mini-invasive approach is feasible; in this setting, the use of intraoperative PTH is mandatory to reduce the incidence of persistent PHP.

Abstract
Preoperative localisation of pathological glands in patients with primary hyperparathyroidism (PHP) is the mainstay for mini-invasive parathyroidectomy. Nevertheless, a not negligible number of patients presents discordant or negative neck ultrasound (US) and 99mTc-Sestamibi (MIBI) scan. The aim of this study was to assess if a mini-invasive approach is feasible in this kind of patients. In this retrospective study were included patients that underwent parathyroidectomy for PHP. Patients were divided into two groups according to concordance of US and MIBI scan results. 242 patients were included: 183 had concordant preoperative studies, and 59 had discordant or negative studies. A mini-invasive approach was possible in 42 (72.9%) patients with unclear preoperative studies, whereas 12 (20.3%) additional patients required conversion to BNE. The incidence of persistent PHP was higher in patients with unclear preoperative studies (8.5% vs 2.7%), but this difference did not reach a statistical significance (p = 0.121). In patients with unclear preoperative studies, a negative result of intraoperative PTH allowed to avoid a persistent disease in 12 patients, while in 3 cases led to an unnecessary additional exploration. In patients with discordant preoperative studies a mini-invasive approach is feasible; in this setting, the use of intraoperative PTH is mandatory to reduce the incidence of persistent PHP.File | Dimensione | Formato | |
