Recently, video-assisted surgical approaches for achalasia have been adopted by many surgeons. Many reports showed that the minimal invasive video-assisted operations for Ihe achalasia revealed such good results as the conventional operations via thoracotomy. In some studies, among the minimal invasive video assisted surgeries for achalasia, the laparascopic assisted operations have some advantages mainly in respect to patient satisfaction over the thoracoscopic assisted surgeries. In this case, the patient had not responded to repeated balloon dilatation, and we made 5 small incisions over the abdominal wall and performed an esophageal myotomy and partial anterior fundoplication by laparascopic guide. The patient's symptoms were almost relieved, and the postoperative radiologic findings were satisfactory.

기관 절개술은 절대적으로 필요한 수술 방법임에도 불구하고 경우에 따라서는 매우 심각한 합병증이나 후유증을 유발하고 있어 가능한 피하는 것이 좋으며 부득이하여 시술을 하더라도 그 적절한 시기를 정하기 어려운 경우가 많다. 특히 유소아에서는 최근에 개량된 삽관튜브의 출현으로 비교적 장기간의 기관삽관이 가능해지자 기관절개술의 적용예가 많이 감소하기는 하였으나 합병증이나 후유증을 너무 우려한 나머지 기관절개술을 기피하거나 적절한 수술시기를 놓쳐 더욱 어려운 입장에 처하게 되기도 한다. 저자들은 1977년도부터 1990년까지 세브란스 병원에서 기관절개술을 시행받은 15세이하의 유소아 환자 94례에서 기관절개술의 원인 질환과 적용시기 및 합병증을 알아보고 기관삽관과의 관계를 후향적으로 조사하여 다음의 결과를 얻었다. 1. 유소아 기관 절개술의 원인 질환은 두부외상이 28례(29.8%)로 가장 많았고, 신경계 질환 17례(18%), 기도 감염 10례(10.6%)의 순이었고 그 외 선천적 기형 종양, 외상, 감염 등으로 다양한 분포를 보였다. 2.기관 절개술전에 기관삽관을 시행하지 않았던 예는 18례(19.1%)이고 기관삽관을 시행했던 예는 76례(80.9%)이며, 38례(40.4%)는 일주이내에 기관절개술을 시행하였고 12례(12.8%)는 2주이내에, 8례(8.5%)는 3주이내, 6례(6.4%)는 4주이내에 시행하였으며 12례(12.8%)는 기관 삽관후 4주이후에 기관절개술을 시행하였다. 3.기관 절개술후, 합병증은 26례(27.7%)에서 있었고 육아조직 형성이 14례(14.9%) 였고 기관 협착이 12례(12.8%)의 순이었다. 4.인공 호흡기률 사용하였던 46례(48.9%)중 14례(14.9%)에서 합병증이 있었고, 인공 호흡기를 사용치 않았던 48례(51.5%)에서는 12례(12.8%)에서 합병증이 발생하였다. 5.삽관 발거를 시행할 수 있었던 예는 47례(50%)였으며, 기관 절개술후 1개월이내에 시행한 예가 21례(16%), 6개월이내 시행한 예가 16례(17%), 2년이내에 시행한 예가 6？(6.4%)였으며 2년 이후 시행할 수 있었던 예도 4례(4.3%) 있었다. 6.기관 절개술 환자중 26례(27.7%)는 원인 질환으로 결국은 사망하였으며, 21례(22.3%)는 삽관 발거를 하지 않은 상태에서 퇴원하여 추적이 불가능하였다.

Median sternotomy incision is world-widely used for open heart surgery, especially in valvular heart disease. But recently, minimally invasive approach by the right parasternal incision for valvular heart disease was introduced with the many merits by small incision. We experienced 1 case of mitral valve repalcement by right parasternal incision and extended transseptal approach. This technique has no specific compli ations or problems compared with the median sternotomy and was proven by the excellent exposure. Cosmetically, the patient was satisfied with the incision.

A tracheostomy is performed to relieve an upper airway obstruction, to facilitate bronchial toilet, to decrease dead space, to assist ventilation and as an elective procedure in head and neck surgery. Many complications are associated with tracheostomy, both in the actual performance of the operation and in the postoperative management. Recently the authors report one case ; a two years old children got a severe burn on face and neck and received tracheostomy and have carried tracheostomy cannula for 10 years, at last the cannula was worn out and the 12 years old boy came to the hospital.

Transabdominal approach in redo coronary artery bypass grafting(CABG) may avoid the risk related to repeat sternotomy. Redo CABG using this approach can be performed safely in selected cases. We report a case of redo off-pump CABG through a transabdominal approach in a 59-year-old woman with recurrent unstable angina after a previous CABG. Through a curvilinear epigastric incision, right gastroepiploic artery(RGEA) was harvested as a graft, and the RGEA-to-right coronary artery anastomosis was performed on the beating heart. A 1-day postoperative angiographic study showed the patent RGEA graft, and she was discharged on postoperative 4th day without any complication.

Various extraoral and intraoral approaches to reduction and fixation of zygomatic complex fractures were used. The method for exposure of inferior orbital area include the subciliary, inferior eyelid, infraorbital rim and conjunctions incisions. For exposure of frontozygomatic suture, lateral brow, coronal and b'ephaloplasty incisions were used. It is necessary that the usual approaches to the inferior and lateral orbit have two incisions. However, lateral canthotomy-conjunctival approach presented on this paper provide optimal exposure to lateral and inferior orbit.

Purpose : We used transparent flexible tube which had provided the good visual field of median nerve when it was used in endoscopic release of transverse carpal ligament and evaluated the safety of that technique. Materials and Methods : We evaluated the 12 patients(20cases) who had been diagnosed as carpal tunnel syndrome and performed by endoscopic carpal tunnel release between Mar. 1997 and Mar. 2000. We used two portal technique and released the transverse carpal ligament with direct supervision of median nerve. Results : 14 cases$(70\%)$ were revealed excellent or good results and 6 cases$(30\%)$ were fair. No serious complications were shown such as nerve injury. Conclusion : We could avoid the complications of endoscopic carpal tunnel release using the transparent flexible tube which had provided tire good circumferential vision around the median nerve and it is unnecessary to maintain the wrist Joint hyperextension state during operation. Also that tube was easily obtainable in hospital so we need not to purchase the expensive operation apparatus.

Background: Minimally invasive cardiac surgery appears to offer certain advantages such as earlier postoperative recovery and a greater cosmetic effect than that achieved through conventional sternotomy. However, this approach has not yet been widely adopted in Korea to replace complex open heart surgery such as mitral valve reconstruction. This study compared the results of robot assisted minimally invasive mitral valve repair with those results of conventional sternotomy. Material and Method: From December 1993 to December 2005, 520 consecutive patients underwent mitral valve reconstruction for mitral regurgitation in our institution. These patients were subdivided according to those whose surgery used the conventional sternotomy approach (Group S, n=432) and those who underwent minimally invasive right anterior thoracotomy (Group M, n=88); we then compared the clinical results of both groups. When we performed minimally invasive right thoracotomy, we used a robot (AESOP 3000) and made an incision less than 5 cm. Result: Our study patients in both groups were similar for their age, gender and preoperative ejection fraction. There were two hospital mortalities in group S. but there was no mortality in the group M patients. Significant reductions in the ICU stay and the postoperative hospital stay were observed in the group M patients compared with the group S patients. However, both the bypass time and the aortic cross-clamp time were significantly longer in the group M patients. In spite of the confined incision in the group M patients, there were no limitations on the mitral valve repair techniques. There was a similar frequency of postoperative significant residual mitral regurgitation in both groups. Conclusion: In this study, the minimally invasive mitral valve repair showed comparable early results with the conventional sternotomy patients. We will now need long-term follow-up of these patients who underwent minimally invasive mitral valve repair, but we anticipate that based on the results of this study, we will begin to routinely perform minimally invasive cardiac surgery as out primary approach for mitral valve reconstruction.
