Abstract

Purpose: Various new techniques in thyroid surgery have been developed to improve visualization and reduce risk of complications. New approaches for robotic endoscopic thyroidectomy help to prevent neck scarring and improve surgical ergonomics. The purpose of this study was to compare the efficacy and adventages of an axillo-breast approach (AB group) and an only-axillary approach (OA group) in robotic endoscopic thyroidectomy. Methods: Between November 2008 and July 2014, axillo-breast approach was performed in 128 patients and only-axillary approach was performed in 128 patients for robotic endoscopic thyroidectomy. We compared tumor characteristics, surgical outcomes, and postoperative complications between the two approaches. The homogeneity between two groups of general characteristics was analyzed by independent t-test, fisher's exact test, Chi-square test. Results: There were no differences in terms of tumor characteristics, extent of thyroidectomy, retrieved nodes, and postoperative complications between the two approaches. The patients in OA group can avoid breast scar. Conclusion: Our techniques of AB and OA approaches for robotic endoscopic thyroidectomy are safe, feasible, and cosmetically excellent procedures. Also the OA approach for robotic endoscopic thyroidectomy is an attractive surgical option for patients with thyroid tumor who want an avoid breast scar.

서론: 통상적인 갑상선 암 수술시 생기는 목의 전면에 있는 흉터를 피하기 위해 여러 다양한 수술 기법들이 고안되고 있다. 저자들이 고안한 로봇 내시경 갑상선 수술법으로 수술을 시행 받은 256예를 대상으로 기구의 변화와 더불어 로봇 내시경적 수술방법(액와 유륜 접근법과 유일-액와 접근법)에 따라 수술 결과를 비교하여 각 수술 방법의 안정성 및 유용성을 확인하고자 하였다. 대상 및 방법: 2008년 11월부터 2014년 7월까지 로봇 내시경 갑상선 수술을 시행 받은 256명의 환자를 대상으로 하였다. 접근방법에 따라 2008년 11월부터 2010년 7월까지 액와-유륜 접근법(Axillo-Breast approach, AB group)이 128례, 2010년 8월부터 2014년 7월까지 유일-액와 접근법(Only-Axillary approach, OA group)이 128예로 구성되었다. 수집된 자료는 SPSS v.12 를 이용하여 실험군과 대조군의 동질성 검정은 independent t-test, fisher's exact test, $x^2$-test로 양측검정을 실시하였다. 결과: 종양의 특성, 수술범위, 채취된 평균 림프절 개수(AB group 5.1개, OA group 6.1개), 수술 후 주요 합병증(AB group 0.8%, OA group 0.8%)은 양 군간에 차이는 없었다. 유일-액와 접근법의 경우 유륜의 흉터를 피할 수 있었다. 결론: 액와-유륜 접근법과 유일-액와 접근을 통한 로봇 내시경적 갑상선 절제술 모두 안전하고 유용한 수술법이다. 로봇 내시경 갑상선 수술에서 유륜의 흉터를 피하고자 하는 경우, 5 mm Maryland dissector 2개를 이용한 유일-액와 접근을 통한 로봇 내시경 갑상선 절제술을 고려해 볼 수 있을 것으로 생각된다.
