Improved preoperative functional and topographic diagnostic techniques and availability of intra-operative hormone monitoring, stimulated the introduction of video-assisted minimally invasive operations in parathyroid and thyroid surgical pathology. The first cases of such pathology operated on in our clinic are presented. The first one is a 62 year old man with renal hyperparathyroidism consecutive to a chronic renal insufficiency and hemodialysis from five and three years respectively. The technique of a minimally invasive gapless resection of all four "adenomised" parathyroid glands using laparoscopic and classic instruments is described. Fragments of one gland are implanted in the left forearm musculature. The second case was a 48 year old woman with a three cm diameter right toxic adenoma. With a lateral 15 mm incision, dissociation of the musculature and adequate moving of the retractors the excision of the thyroid nodule was done in 25'. The video-assisted minimally invasive approach allows magnification and adequate identification and removal of endocrine secreting tissues in thyroid and parathyroid pathology. The authors believe that these techniques represent a feasible and attractive alternative to conventional surgery.
