Background. In the era of minimal access thyroid surgery, the terms minimal access and minimally invasive are often used interchangeably and in most instances this is far from being accurate. The aim of this article is to examine the characteristics and potential of one of the first minimal access thyroid procedures described; minimally invasive vi...
BRAF mutations represent the most common genetic alteration in papillary thyroid carcinoma (PTC). The p.V600E mutation is specific for the classic and tall-cell variants of PTC and has been associated with a more aggressive biologic behavior. On the other hand, the p.K601E mutation is peculiar to the follicular variant of PTC, and seems to be a fav...
Background. Since the early 1990s endoscopic adrenalectomy has become the gold standard surgical approach to the adrenal gland with the most widely used approach being lateral transperitoneal adrenalectomy (LTA). Posterior retroperitonoscopic adrenalectomy (PRA) is another safe and effective approach to the adrenal gland. However, it has not gained...
Targeted parathyroid surgery also referred to as minimally invasive parathyroidectomy has replaced full neck exploration as the preferred surgical approach to primary hyperparathyroidism. This is attributed to the ability to accurately localize enlarged parathyroid glands preoperatively and obtain objective evidence of adequate resection intraopera...
