Inadvertent parathyroidectomy risk factors in 1,373 thyroidectomies-male gender and presence of lymphadenopathy, but not size of gland, independently increase the risk.

Background: Inadvertent parathyroidectomy (IP) during thyroid operations is a recognised phenomenon. We evaluated the incidence of IP during thyroid operations in a large case-series and identified the risk factors involved.

Methods: Retrospective review of all thyroidectomy operations [total thyroidectomies (TT) and near-total thyroidectomies (NTT)] performed in a single institution from January 2004 to January 2009.

Minimally invasive parathyroidectomy in patients with previous endocrine surgery.

Objective: Previous endocrine neck surgery (PENS) in patients with sporadic primary hyperparathyroidism (PHP) is considered a contraindication for minimally invasive parathyroidectomy (MIP). The purpose of our study was to determine the effectiveness of MIP in such patients.

Methods: From January 2004 to December 2009, 270 patients with PHP were treated in our department; 30 had had PENS in the past.
