Background Minimally invasive video-assisted thyroidectomy (MIVAT) proved to be safe and effective in the treatment of both benign andmalignant disease. The aim of the present study is to compare MIVAT approach with conventional approach for total thyroidectomy in a group of 99 pediatric patients operated in the Department of General Surgery of the University of Pisa between March 2007 and July 2012. Patients A total of 99 pediatric patients under the age of 18 years with thyroid disease referred to our Department to undergo total thyroidectomy. Patients were divided into two groups according to the surgical technique performed: 34/99 (34.3%) patients (MIVAT group [MG]) and 65/99 (65.7%) patients, (conventional group [CG]) who underwent total thyroidectomy, respectively, with MIVAT approach and conventional approach. Results In MG mean operative time for total thyroidectomy was 40 ± 6.57 minutes (range 30-60 min); postoperative hospital stay was 1 day for 18 patients (53%), 2 days for 12 patients (35.25%), 3 days for 4 patients (11.8%); transient hypoparathyroidism (hypoPTH) was observed in 12 cases (35.3%) and permanent hypoPTH in 2 cases (5.9%); transient postoperative unilateral vocal cord palsy was observed in 2 patients (5.9%). In CGmean operative time for total thyroidectomy was 49.3 ± 12.9 minutes (range 30-80 min); postoperative hospital stay was 1 day for 16 patients (24.6%), 2 days for 40 patients (61.5%), 3 days for 8 patients (12.3%), and 4 days for 1 patient (1.6%); transient hypoPTH was observed in 23 cases (35.4%) and permanent hypoPTH in 4 cases (6.1%), who needed therapy with calcitriol and calcium carbonate; transient postoperative unilateral vocal cord palsy was observed in 4 patients (6.1%). There were no cases of permanent vocal cord paralysis in both groups. The correlation between two groups of patients showed that mean operative time was significantly lower in MG (p = 0.0007). Conclusion Pediatric patients of MG showed a significantly lower operative time and postoperative hospital stay with respect to pediatric patients of CG if compared with conventional technique. This result with the evidence of similar degree of completeness and rate of postoperative complications make MIVAT a valid option for the treatment of pediatric patients when performed by a well-trained staff in a third referral center.

Amiodarone-induced thyrotoxicosis is a life-threatening condition. A prompt control of thyrotoxicosis is obtained by thyroidectomy. Preparation with iopanoic acid proved to be very effective in reducing cardiovascular complications. Nevertheless, general anesthesia and extensive surgery may affect negatively patients also after adequate preparation. Safety and efficacy of minimally invasive video-assisted thyroidectomy performed under regional anesthesia (bilateral modified deep cervical block) in patients with amiodarone-induced thyrotoxicosis was evaluated. Eight patients with amiodarone-induced thyrotoxicosis (three with type I and five with type II), mean age 66.2 years, were prepared with iopanoic acid. There were five men and three women. Three patients had dilatative cardiomyopathy, three had heart failure secondary to severe myocardial infarction, and two had refractory unstable rhythm disorders. Minimally invasive video-assisted thyroidectomy was performed under regional anesthesia. Mean operative time was 55.5 min. During surgery, lung and heart function remained well and no surgical complications occurred. After surgery, all patients remained on amiodarone therapy and two patients were subsequently removed from the checklist for heart transplantation. Minimally invasive video-assisted thyroidectomy under regional anesthesia can be proposed as resolution of amiodarone-induced thyrotoxicosis in high risk patients with severe cardiac disorders, after preparation with iopanoic acid.

Background and aims: Minimally invasive video-assisted thyroidectomy (MIVAT) was set up and introduced in our department in 1998. Its results, after an acceptable relapse, can now be evaluated, also speculating on new possible indications. Patients and methods: The procedure is based on a unique incision in the central neck, 2 cm above the sternal notch, using small conventional retractors and needlescopic (2 mm) reusable instruments. Haemostasis is achieved by a harmonic scalpel. Patients, 833, underwent MIVAT since June 1998. There were 715 females and 118 males (ratio 4:1). Lobectomy was carried out in 323 (38.7%) patients, total thyroidectomy in 510 (61.2%) patients. Results: Mean operative time of lobectomy was 36.2 min (range: 20–120); for total thyroidectomy, 46.1 min (30–130). Conversion to standard cervicotomy was required in 16 cases (1.9%); Operative complications were represented by transient monolateral recurrent nerve palsy in eight cases (0.9%), definitive monolateral recurrent nerve palsy in seven cases (0.8%). Twenty patients exhibited a hypoparathyroidism, which corresponds to 3.9% of total thyroidectomies performed, but only two showed permanent hypoparathyroidism (0.3%). Conclusion: MIVAT can be considered a safe operation offering significant cosmetic advantages with possible new promising indications such as prophylactic thyroidectomy in rearranged during transfection (RET) gene mutation carriers. It is still limited to a minority of patients, in particular, in endemic goitre countries. [ABSTRACT FROM AUTHOR]
