RESUMO
PURPOSE: With recent developments in endoscopic surgery for thyroid tumors, several approaches have been applied to endoscopic neck surgery. Gasless endoscopic thyroidectomy has some advantages over gas insufflating surgery. We evaluated the role of gasless endoscopic thyroidectomies on various thyroid tumors including malignant thyroid tumors. METHODS: We performed thyroidectomies for a total of 195 patients who were admitted to Uijongbu St. Mary's Hospital from November 1999 to February 2002. We compared the clinical data of 100 patients who received gasless endoscopic thyroidectomies with the data of 95 patients who underwent conventional thyroidectomies. Furthermore, we subclassified the 100 patients who received a gasless endoscopic thyroidectomy into two groups, before and after the start of 2001. RESULTS: The analysis of the clinical data showed that an endoscopic thyroidectomy gave superior results with respect to the time of postoperative recovery and cosmetic results. Also, the patients in the second half group showed significantly shorter operation times reduced from 153.4 min. to 128.6 min. and length of hospital stay similarly reduced(3.55 days vs. 5.35 days). CONCLUSION: A gasless endoscopic thyroidectomy is a safe and technically feasible alternative to a conventional thyroi-dectomy in benign and early malignant tumors, and provides good cosmetic results.
