Abstract

Background: The interest in robotic cardiac surgery has recently grown but there has not been much clinical research reported on this. The aim of this study is to examine our initial experience, since August 2007, with robotic cardiac surgery using the da $Vince^{TM}$ surgical system and to evaluate the feasibility and safety of it. Material and Method: Between August and December 2007, a total of 20 patients underwent robotic cardiac surgery using the da Vinci surgical system. For mitral valve repair (n=11), tricuspid valve repair (n=1), and ASD repair (n=1), cannulation, antegrade cardioplegia and transthoracic aortic cross-clamping were conducted for the right femoral vessels and the right internal jugular vein. For minimally invasive direct CABG (MIDCAB) (n=7), the internal thoracic artery (ITA) was harvested with the da Vinci surgical system. Result: The mean age of the patients was 50.1 (range: $26{\sim}78$) years. Three concomitant Maze procedures and one tricuspid annuloplasty were combined with mitral valve repair. The mean cardiopulmonary bypass time was $208.0{\pm}61.3$ minutes and the aortic cross clamp time was $158.8{\pm}40.6$ minutes. No patients showed more than mild mitral regurgitation after repair and the median hospital stay was 4 days. The robotic-harvested ITA was used for either left ITA (n=6) or bilateral ITA (n=1). The mean harvest time was $43.2{\pm}12.0$ minutes. The harvested ITA showed good flow and it was anastomosed under direct vision after left anterolateral thoracotomy. The patency of all the grafts was 100% (18/18) in MIDCAB. Conclusion: Robotic cardiac surgery using the da Vinci surgical system was variously adapted to areas such as mitral and tricuspid valve repair, ASD repair and ITA harvest for MIDCAB. The early results of the robotic cardiac surgery showed its safety and feasibility. With this primary report, we anticipate that clinical applications and further studies on robotic cardiac surgery using the da Vinci surgical system will be actively conducted in Korea.

배경: 최근 수술 로봇을 이용한 심장수술에 대한 관심이 증가하고 있으나, 이에 대한 임상연구는 제한적이다. 본 연구는 2007년 8월부터 저자들에 의해 시행된 다빈치 수술 로봇을 이용한 심장수술의 조기 임상 경험을 보고하고, 로봇 심장수술 실현성 및 안정성을 살펴보고자 하였다. 대상 및 방법: 2007년 8월부터 12월까지 총 20명의 환자에게 다빈치 수술로봇을 이용한 심장수술을 시행하였다. 승모판막 질환(n=11), 삼첨판막 질환(n=1), 심방중격결손증(n=1)의 수술시에는 우측 대퇴 동정맥 및 우측 내경정맥을 이용한 말초 삽관 후 체외 순환을 시행하였고, 전방성 심정지액 투입 및 흘곽의 늑간을 통한 대동맥 겸자를 시행한 후 개심술을 시행하였다. 7명의 환자에서 최소 침습적 관상동맥 우회술(MIDCAB)을 시행하기 위하여 다빈치 수술로봇을 이용하여 좌측 혹은 양측 내흉동맥을 박리하였다. 결과: 환자의 평균 나이는 $50.1{\pm}15.1$세($26{\sim}78$)였으며, 11예의 승모판막 성형술시 3예의 Maze 수술 및 1예의 삼첨판막 성형술이 동반되었다. 평균 체외순환시간은 $208.0{\pm}61.3$분, 평균대동맥 차단시간은 $158.8{\pm}40.6$분이었다. 승모판막 성형술 후 2도를 초과하는 잔존하는 승모판막 역류는 없었으며 수술 후 재원 기간의 중간값은 4일이었다. 다빈치 수술로봇을 이용한 내흉동맥의 박리는 6명의 환자에서 좌측 내흉동맥을 박리하였고, 1명의 환자에서 양측 내흉동맥을 박리하였으며 평균 내흉동맥 박리 시간은 $43.2{\pm}12.0$분이었다. 박리된 내흉동맥은 양호한 혈류를 보였으며, 좌전 개흉술 후 직접시하에서 문합을 시행하였다. MIDCAB으로 시행한 문합의 개통률은 100% (18/18)였다. 결론: 다빈치 수술로봇을 이용한 심장수술은 승모판막 성형술, 삼첨판막 성형술, 심방중격 결손의 교정 및 관상동맥 우회술을 위한 내흉동맥의 박리 등에서 다양하게 적용되었으며, 비교적 안전하고 만족할만한 조기성적을 보였다. 본 연구를 계기로 국내에서도 다빈치 수술로봇을 이용한 심장수술의 임상적용 및 임상연구가 활발하게 진행될 것을 기대한다.
