Asian perspective on endoscopic thyroidectomy -- a review of 193 cases.

Endoscopic surgery has become widely used, so much so that recent technical and mechanical advances have led to "endoscopic surgery" being synonymous with "minimally invasive surgery". In particular, endoscopic thyroid surgery has developed rapidly and been increasingly refined in recent years. The incidence of thyroid diseases is markedly higher in women than in men, and operations for these diseases result in a scar on the anterior neck that is exposed when open-necked clothing is worn. Therefore, a technique for endoscopic endocrine neck surgery that results in a better cosmetic appearance is desirable. We have developed a totally gasless endoscopic surgical technique using an anterior neck-skin lifting method for thyroid and parathyroid diseases. This technique is called the video-assisted neck surgery (VANS) method. Since our original report, we have treated more than 200 cases of thyroid and parathyroid disease using this technique. In cases of benign thyroid tumours, near total lobectomy was the most common procedure followed by total lobectomy. The maximum resected tumour size was 7.4 cm in diameter. For malignant tumours, the indication for the VANS method was limited to thyroid papillary microcarcinomas measuring less than 1 cm in diameter. Total lobectomy and prophylactic neck dissection were performed in all 10 of these cases. A subtotal thyroidectomy was performed for only a few cases of Graves' disease. The operating time and the amount of bleeding were statistically significantly reduced, as the surgeon gained experience with the technique. In conclusion, the VANS method is a feasible, practical and safe procedure, with excellent cosmetic benefits.
