Background: Minimally invasive cardiac surgery has emerged as an alternative to conventional open surgery. This report reviews our experience with atrial septal defect using the da VinciTM surgical robot system. Materials and Methods: This retrospective study included 50 consecutive patients who underwent atrial septal defect repair using the da VinciTM surgical robot system between October 2007 and May 2011. Among these, 13 patients (26%) were approached through a totally endoscopic approach and the others by mini-thoracotomy. Nineteen patients had concomitant procedures including tricuspid annuloplasty (n=10), mitral valvuloplasty (n=9), and maze procedure (n=4). The mean follow-up duration was $16.9{\pm}10.4$ months. Results: No remnant interatrial shunt was detected by intraoperative or postoperative echocardiography. The atrial septal defects were mainly repaired by Gore-Tex patch closure (80%). There was no operative mortality or serious surgical complications. The aortic cross clamping time and cardiopulmonary bypass time were $74.1{\pm}32.2$ and $157.6{\pm}49.7$ minutes, respectively. The postoperative hospital stay was $5.5{\pm}3.3$ days. Conclusion: The atrial septal defect repair with concomitant procedures like mitral valve repair or tricuspid valve repair using the da VinciTM system is a feasible method. In addition, in selected patients, complete port access can be helpful for better cosmetic results and less musculoskeletal injury.

정형외과 수술의 임상적 결과에 영향을 미치는 요소는 여러 가지가 있지만 수술적 수기가 가장 중요한 요인이며 로봇공학은 술기를 보다 정확하고 일관되게 수행하기 위해 도입되었다. 정형외과 영역에서는 20년 전부터 로봇수술을 사용하였으나 실용성 문제와 합병증의 발생으로 일부 로봇은 도태되었으며 단점을 개선한 로봇이 소개되고 있다. 대부분의 로봇수술은 인공관절수술 분야에서 시행되었고 치환물의 정렬과 위치 선정에서 우수한 것으로 보고되고 있다. 그러나 임상적 결과의 우수성, 실용성, 가성비 등의 측면에서 제한점이 있고 일부 로봇수술에서는 합병증 발생 빈도가 높다는 보고가 있었다. 초기 로봇수술은 수술자의 개입 없이 계획된 수술이 진행되는 능동형 로봇수술이 주를 이루었으나 최근에는 수술과정에서 실시간 피드백을 통해 술자가 술 전 계획을 변경할 수 있고, 햅틱 경계 내에서 제한된 골절제를 함으로써 주요 혈관, 신경, 인대 등의 손상을 최소화할 수 있는 반능동형 로봇수술이 소개되고 있다.

목적 급성 담낭염은 간동맥 화학 색전술 후에 발생하는 비교적 드물지 않게 발생하는 합병증이며, 대부분 수술적 혹은 중재적 치료 없이 호전된다. 간동맥 화학 색전술 직후에 촬영한 cone beam CT 소견을 이용하여, 수술적 혹은 중재적 치료를 필요로 하는 담낭염의 발생률과 위험인자를 분석하고자 하였다. 대상과 방법 본 연구에서는 6년 동안 시행된 2633건의 간동맥 화학 색전술에 대해 후향적으로 분석하였다. 그중 시술 직후에 촬영한 cone beam CT에서 담낭에 색전 물질이 남아 있는 120명을 선택하여 급성 담낭염의 발생률과 위험인자에 대해 분석하였다. 결과 수술적 혹은 중재적 치료를 필요로 하는 담낭염의 전체 발생률은 0.45%였다. 색전 물질이 남아 있는 환자들 중에서는 10%에서 담낭염이 발생했다. 담낭염이 발생한 12명 중 8명은 담낭동맥의 색전술을 받은 환자들이었다. 결론 대부분의 담낭의 색전물질 침적은 추가적인 치료를 필요로 하지 않고 호전되지만, 담낭동맥의 색전술을 받은 경우에는 담낭염의 발생률이 높아 면밀한 모니터링이 필요하다.

Obstructive Sleep Apnea Syndrome(OSAS), that is a complex disease of neuromuscular, respiratory and cardiovascular system, can be cured by various treatment such as weight control, medical and surgical intervention. As most of OSAS may be caused by various anatomical abnormalities, preoperative evaluation for exact anatomical site of obstruction must be needed. And various diagnostic procedures such as fiberoptic nasopharyngoscopy, Mueller test, cinefluoroscopy, cephalometry, computerized tomography, polysomnography would be used for this purpose. Uvulopalotopharyngplasty is currently the most popular method for the patient with OSAS among various surgical maneuvers and is very effective for the relieving the symptoms as like snoring, daytime somnolence, and nocturnal restlessness etc. Although subjective improvement is not compatible with it's objective assessment in postoperative evaluation for it's results, uvulopalatopharyngoplasty could be a recommandable surgical procedure because of it's ample effectiveness in promoting symptom improvement without any risk of serious complications.

Perianal Crohn's disease is a major problem that impair quality of life. This article reviews the current surgical treatment of Crohn's perianal fistula. Fistulotomy and loose seton are commonly used surgical methods for treatment of perianal Crohn's disease. Mucosal advancement flap and fibrin glue are used in this treatment, despite a lake of controlled trials. Fecal diversion is disturbingly high in complicated complex perianal fistula in Crohn's disease. Ligation of intersphincteric fistula and autologous or allogenic stem cells are new surgical procedures for treatment of Crohn's disease that need further studies. Treatment success might be improved by multimodal treatment and new surgical and medical treatment options.

Thirteen patients with cyanotic cardiac malformations having more complex intracardiac defects, hemodynamics and operative procedures than ones in Tetralogy of Fallot undertaken total surgical corrections from July 1981 to August 1985. The cases of corrective surgery for complex cardiac malformations were 3.9% of all congenital cardiac malformations and 12.6% of cyanotic cardiac malformations. Six patients died within 30 days after surgery. So operative mortality was 46%; Transposition of the great arteries, two of 4 patients, due to low cardiac output syndrome and tracheal bleeding ; Univentricular heart, one of 3 patients, due to bleeding; Corrected transposition of the great arteries, one of 2 patients, due to acute heart failure; Tricuspid atresia, one of 2 patients, due to low cardiac output syndrome; Double outlet right ventricle, one of single patient, due to respiratory failure. The cases of surgical correction for complex cardiac malformations are progressively increasing in numbers. The more accurate evaluation of anatomical condition and hemodynamics in preoperative diagnosis, studies on applicable surgical procedure and perioperative care of patients are necessary in the improvement of clinical and surgical results.

The origin and growth of laryngology is inseparably linked to the development of endoscopic surgery of the larynx. Phonomicrosurgery is a means of maximally preserving the layered microstructure of the vocal fold, that is, the epithelium and lamina propria. Phonomicrosurgery has developed from convergence of micro laryngoscopic surgical technique theory and the mucosal wave theory of laryngeal sound production. Improvements in technology (i.e., laryngoscopes, handled instruments, and lasers), which in part arise from developments in more frequently performed minimally invasive surgical procedures, will probably facilitate the next generation of procedural innovations. The best methods of optimizing phonosurgical outcomes include making an accurate diagnosis, completing a comprehensive voice evaluation, providing sufficient preoperative therapy, carefully selecting patients to undergo phonomicrosurgical procedures, and requiring sufficient postoperative rest and therapy. Phonomicrosurgery will continue to evolve as a result of the interdependent collaboration of surgeons with voice scientists, speech pathologist, and other voice professionals.

The open Broström procedure is considered the surgery of choice for treating chronic lateral ankle instability. The role of arthroscopy has gained popularity in the surgical treatment of chronic lateral ankle instability, partly for the ability to manage the intra-articular pathology combined with ankle instability. Arthroscopic techniques can be divided broadly into the arthroscopic-assisted Broström technique and arthroscopic all-inside ligament repair. The clinical results of these arthroscopic techniques are similar to open procedures. The arthroscopic technique may be an excellent alternative to the open Broström procedure in treating chronic lateral ankle instability when applying the appropriate indications.
