Introduction: Minimally invasive techniques in thyroid surgery including video-assisted technique originally described by Miccoli have been accepted in several continents for more than 10 years.

Aim: To analyze our preliminary results from minimally invasive video-assisted thyroidectomy (MIVAT) and to evaluate the feasibility and effects of this method in a general department over a 4-year period.

Material and methods: Initial experience was presented based on a series of 200 patients selected for MIVAT at the General Surgery Department of Yantai Yuhuangding Hospital affiliated with Qingdao University during the period from May 2008 to June 2012. The enrolling criteria were rigorously observed. An above sternal incision with average length of 2.5 cm (1.5–3.0 cm) was made. Clinicopathologic characteristics, postoperative pain, length of hospital stay, cosmetic results and complications were retrospectively analyzed.

Results: All patients received general anesthesia. Thyroid unilateral lobectomy was successfully accomplished in 108 cases, total thyroidectomy in 84, and partial lobectomy in 8. Conversion to standard conventional thyroidectomy was required in 6 patients (3%) because of thyroiditis and bleeding. The mean lymph node yield of the cancer specimens was 3.6 per patient. Permanent unilateral recurrent laryngeal nerve (RLN) palsy occurred in 1 case (0.5%), transient unilateral RLN palsy in 6 patients (3.0%, complete recovery after 1–6 months), and transient hypocalcemia in 7 patients (3.5%). No definitive hypocalcemia was observed. No postoperative hematomas occurred. Postoperative pain was endurable. The cosmetic result was excellent in most cases.

Conclusions: The MIVAT is feasible and safe in selected patients, with better results comparable to conventional thyroidectomy. The MIVAT can also be performed in a general surgery department.
