Purpose: The reparability of rotator cuff tears is very important to establish the indication of the surgical treatment of rotator cuff tears. We reviewed the factors that effect to reparability of rotator cuff tears, and considered about the surgical indication of rotator cuff tears. Materials and Methods: The reparability was considered by the surgical reparability and the postoperative healing potentials of rotator cuff. The natural history of rotator cuff tear gives us the information to make decision about the surgical treatment or the conservative treatment. Results: There are 3 general categories of factors that help predict the healing potential of a rotator cuff tear. These include surgical technique, biology, and environmental issues. Surgeon can control the surgical technique by himself. The control of biology comes from careful operative indications by age, acute trauma history, chronicity, and tear size. And the control of environmental factor can give better outcomes by cessation of smoking and nonsteroidal anti-inflammatory drug (NSAID). Conclusion: A better understanding of the natural history and the reparability of rotator cuff tear will help us to estabilish the indication of surgical treatement of rotoator cuff tears, and lead to satisfactory clinical outcomes.

본 연구는 수술에 사용하는 생리식염수가 수술의 종류와 수술진행단계에 따른 오염수준을 파악하여 생리식염수의 적절한 교환시점과 교환방법을 제시하기 위하여 시도되었다. 1500 병상 규모의 대학병원에서 1명의 일반외과 의사가 집도한 37건의 수술을 대상으로 하였다. 37개의 수술 각각에서 피부 절개전, 장기절제 후, 그리고 피부 봉합시의 3 시점에서 수술에 사용된 생리식염수와 공기에 노출시킨 생리식염수에서 각각 50 mL의 생리식염수를 채취하여 얻은 균주의 수를 비교하였다. 공기에 노출시킨 생리식염수에 비해 수술에 사용된 생리식염수에서 균주가 보다 많이 검출된 것으로 나타났다. 특히 수술의 종류에 관계없이 수술 마지막 단계 즉 피부봉합 단계에서 수술에 사용된 생리식염수의 오염수준이 급격히 증가한 반면 공기에 노출시킨 생리식염수의 오염수준 변화는 미미했다. 수술에 사용한 생리식염수에서는 Enterococcus(9.5%), Enterobacter species(4.6%), E. col i(2.8%), Alcaligenes species(1.2%), Klebsiella species(0.9%) and Pasteurella multocida(0.8%) 등의 균주가 검출되었으나 공기에 노출시킨 생리식염수에서는 이러한 균종이 검출되지 않았다. 수술실의 공기가 수술에 사용하는 생리식염수의 오염요인으로 작용하기보다는 수술조직이 생리식염수의 오염요인으로 작용하는 것으로 사료된다. 특히 수술에 사용하는 생리식염수의 오염가능성을 최소화시키기 위해 수술소요 시간이 길어지거나 또는 오염 수술의 경우 절제부위가 봉합된 후에 수술에 사용하는 생리식염수, 생리식염수를 담는 용기 및 봉합에 이용되는 봉합감자 등을 새로이 준비하여 피부 봉합에 이용해야 할 것으로 사료된다.

One of the most common cosmetic surgery, the blepharoplasty can be divided two method. there were incisional method and sutured method. Authors try to understand the anatomic difference between the oriental upper eyelids and apply the surgical techniques of constructing upper eyelid crease of oriental case effectively. And we discussed the postoperative complications of the blepharoplasty and proposed the solve of these problems. The sutured method of blepharoplasty was more simple technique than conventional incision method and had low occurrence of complications. Even though slight recurrence, suture method was more esthetic due to no scar formation.

Purpose: This study was designed to investigate the rate of incidence, location and the clinical value of the rotator cuff retear by analyzing MRI scans, which was taken after an arthroscopic rotator cuff repair. Materials and Methods: This study included a total of 109 patients, who underwent a shoulder MRI scan after an average of 10.6 months later from the arthroscopic rotator cuff repair. We only defined the 'retear' when the Sugaya type IV and V was observed in the sagittal section of the MRI. The location of the retear was divided into the medial and lateral areas by the site, which was 1 cm medial to the anchor insertion. We investigated the incidence rate and the location of the retear, in terms of the age, sex, initial tear size and the suture method. Also, we compared the functional score of the retear group and the non-retear group, after an average of 13.9 months follow-up. Results: There were 38 of the 109 patients that showed the rotator cuff retear. Of these patients, 25 were male patients, and 13 were female patients. Of the 38 patients with the rotator cuff retear, 21 patients were included in the <3 cm retear group, and 17 were included in the ${\geqq}3$ cm retear group. At the end of the follow up period, all 109 patients showed a statistical significant improvement in the shoulder functional score. Conclusion: According to the follow up of the MRI scan, which was taken after the rotator cuff repair, the retear rate reached 34.9 %, and there were no significant differences on the age and the suture method. More rotator cuff retear occurred in male patients, and the initial tear size was positively correlated with the incidence rate of the rotator cuff retear. Also, the retear was more frequently observed at the medial side. That is because when the suture was performed, excessive tension was loaded on the medial side of the suture site.

The authors introduce an operative technique which is simple and effective for the treatment of the large prepatellar bursitis, avoiding problems by the conventional open technique such as tender scar, infection and recurrence. We treated three cases of the large refractory prepatellar bursitis caused by acute direct trauma. Bursectomies were performed by using an arthroscope and percutaneous multiple sutures were applied to the overlying skin with mattress fashion. There were no complications after treatment over one year follow-up. We suggest that this technique is very useful, greatly minimizes the chance of recurrence and reduces the possibility of post-operative infection.

Double-outlet left ventricle(DOLV) is a rare congenital cardiac malformation, defined as the origin of both the aorta and the pulmonary artery being entirely or predominantly above the morphologically left ventricle, which is difficult to diagnose accurately. A 3-year old male was admitted for cyanosis and dyspnea. At the age of 2 months, he had undergone pulmonary artery banding and coarctoplasty. He was diagnosed as DOLV with subaortic ventricular septal defect(VSD). Biventricular repair was achieved by patch closure of VSD, primary closure of PFO, and pulmonary trunk translocation from left ventricle to right ventricle. The advantages of this procedure using native tissue for right ventricular outflow tract reconstruction are growth potential and preserved valve function, which contribute to a decreased likelihood of reoperation related to the right ventricular dysfunction related to pulmonary insufficiency.

Since 1960, there has been growing recognition that the moving images reveal the 'realistic illusion(L'illusion r$\acute{e}$aliste)' rather than the reality itself and many theorists and film directors have tried to suggest the methodology to solve the problem of verisimilitude of the moving images. In this paper, we describe through the case analysis of the practical use of 'off-screen space' as a methodology which actualize the reality in documentaries, by minimizing the 'suture' effect which occurs the problem of verisimilitude, based on the theories of Bazin and Burch. We, consequently, believe that the application of the 'off-screen space' could be one of the appropriate possibility for the successful representation of reality in documentaries.

The cardiac anatomic position immediately beneath the sternum leaves it vulnerable to injury when this bone is fractured. Cardiac rupture, however, is uncommon but survival following this injury is rare. We report the case of one patient who survived right ventricle perforation resulting from sternal fracture. The patient developed signs of pericardial tamponade and was brought to the operating theatre immediately for surgery through the emergency anterolateral thoracotomy Perforation of th right ventricle was repaired by direct closure without cardiopulmonary bypass. We believe that patients with cardiac rupture who reach the hospital alive can often be saved by prompt diagnosis and surgery.

The occurrence of thrombotic occlusion & endothelial injuries at the site of anastomosis have been considered as major problems in microvascular surgery. The purpose of this study was to ascertain whether a end-in-end(sleeve, telescope) anastomosis compared favorably with end-to-end anastomosis in healing procedures on the endothelium and to study the possibility of clinical application in end-in-end method. The microvascular anastomoses have been performed with end-in-end method in the femoral arteries of 20 rats group, also with end-to-end method on the same arteries of another 20 rats group, and then the four anastomosed vessels in subdivided groups on each group were taken after period of 1, 3, 7, 14, 21 days following by anastomoses for scanning electron microscope observation. The results were as following: 1. The patency rate was 90% in the end-in-end group and 85%in the end-to-end group and late thrombus occurred at 7, 14 days on both groups, which suggested -consistent monitoring of patency was required for two weeks at least. 2. Platelet aggregates at the site of anastomosis began to organize on post-operation 3 days and in the end-in-end group, the initially decreased lumen of inserted vessel was gradually increasing on 7 days due to atrophy of the medial layers. 3. Re-endothelialization was completed between 7 and 14 days in end-in-end group, whereas between 14 and 21 days in end-to-end group.
