[Minimally invasive video-assisted thyroidectomy (MIVAT)]

Abstract

Minimally invasive video-assisted thyroidectomy (MIVAT) was published in 1998. In this paper authors describe their initial experiences with this new technique, which is the first publication in their country on this topic based on authors knowledge. Ten patients were selected for MIVAT. Selection criteria were nodule size less than 30 mm, thyroid lobe volume less than 20 ml, no thyroiditis, no previous neck surgery or irradiation. The procedure was carried out through a 20-25 mm central incision above the sternal notch. Dissection was performed under endoscopic vision, using endoscopic, some special and conventional instruments. Authors performed 1 total thyroidectomy, 6 lobectomies, 2 lobectomies with subtotal resection on the opposite side, and 1 resection of thyroid isthmus. Mean operative time was 77 minutes. No conversion to open procedure was performed. No recurrent laryngeal nerve palsy or postoperative hypocalcemia were observed postoperatively. The mean hospital stay was 2 days. The cosmetic result and the postoperative distress were considered very good by the patients. The authors conclude that MIVAT is a safe and feasible procedure. The indications are limited, but in this small group of patients offer excellent cosmetic results with less postoperative distress.
