Minimally invasive video-assisted thyroidectomy

Background: In this paper we describe the results of our personal technique for minimally invasive video-assisted thyroidectomy (MIVAT). Methods: Sixty-seven patients were selected for MIVAT. Selection criteria w ere nodule size less than 30 mm, thyroid volume less than 20 mL, no thyroid itis, no previous neck surgery or irradiation. The procedure, totally gasle ss. is carried out through a 15-mm central incision above the sternal notch . Dissection is performed under endoscopic vision, using conventional and e ndoscopic instruments. Results: We pet-formed 51 lobectomies and 15 total thyroidectomies. Mean op erative time was 73.6 minutes for lobectomy and 109.6 minutes for total thy roidectomy. Conversion to open procedure was required twice 0%). We observe d 2 cases of transient postoperative hypocalcemia and I case of transient r ecurrent laryngeal nerve palsy, The cosmetic result was considered excellen t by most patients. Conclusions: MIVAT is safe and feasible, The indications are limited at pre sent, but the results are encouraging, and we are optimistic about the futu re expansion of its applicability.
