Abstract

Background: The conventional thyroidectomy is the most frequent surgical procedure for thyroidal surgical disease. From several years were introduced minimally invasive approaches to thyroid surgery. These new procedures improved the incidence of postoperative pain, cosmetic results, patient’s quality of life, postoperative morbidity. The minimally invasive video-assisted thyroidectomy (MIVAT) is a minimally invasive procedure that uses a minicervicotomy to treat thyroidal diseases.
Methods: We present our experience on 497 consecutively treated patients with MIVAT technique. We analyzed the mean age, sex, mean operative time, rate of bleeding, hypocalcemia, transitory and definitive nerve palsy (6 months after the procedure), postoperative pain scale from 0 to 10 at 1 hour and 24 hours after surgery, mean hospital stay.
Results: The indications to treat were related to preoperative diagnosis: 182 THYR 6, 184 THYR 3–4, 27 plummer, 24 basedow, 28 toxic goiter, 52 goiter. On 497 cases we have reported 1 case of bleeding (0,2%), 12 (2,4%) cases of transitory nerve palsy and 4 (0,8%) definitive nerve palsy. The rate of serologic hypocalcemia was 24.9% (124 cases) and clinical in 7.2% (36 cases); 1 case of hypoparathyroidism (0.2%).
Conclusions: The MIVAT is a safe approach to surgical thyroid disease, the cost are similar to CT as the adverse events. The minicervicotomy is really a minimally invasive tissue dissection.
