비디오 종격동경을 이용한 수술은 좁은 시야와 제한된 수술 기구의 이용으로 수술 적응증의 폭넓은 확대가 어렵지만, 종격동, 폐, 흉막 질환에서 진단 혹은 치료 방법의 하나로서 중요한 영역을 확보하고 있다.

Background: Nuss procedure is a minimally invasive technique for correcting the pectus excavatum. But there are some limitations of correcting the complex anomaly or grown-up patients. Material and Method: we retrospectively reviewed 135 consecutive patients who underwent repair of pectus excavatum by the Nuss procedure and its modifications between November 1999 and December 2004. We analyzed the computed tomography, age on operation, operative technique, and complications. Result: We operated 135 patients of pectus excavatum during 62 months. Total number of operations about Nuss procedure is 216, including bar removal procedure of 64 cases, redo Nuss procedures of 47 cases. We modified the point of bar insertion to the hinge point, made a shoulder in the bar to prevent a displacement. And then we changed the fixation material from Vicryl to steel wire. If the patients are old, we retract the sternum during bar rotation and fixation. Until 2002, the number of redo Nuss operations were 17, complications were 23. but, after modifications, the number of redo Nuss operation were 0, complications were 2. Conclusion: This result indicates that our modifications of Nuss operation is effective, and could decrease the number of redo Nuss operation and complications.

족부의 교정을 위해서는 비정상적인 상태 및 원인 그 치료법에 대해서 충분히 이해해야 할 것으로 생각되며, 비 척행족에 대해서는 먼저 정확한 원인 인자의 파악과 수술전 평가, 수술의 선택, 수술의 범위등을 정해야 한다. 이렇게 함으로써 변형에 대한 충분한 교정이 가능하며, 수술후 예후가 좋은 척행족으로 될 것이다. 그리고 위에서 밝힌 치료의 원칙은 변하지 않겠지만, 관절 고정술을 대체하여 다른 남은 관절에 영향을 주지 않으면서 더 많은 유연성을 가질 수 있는 기능있는 족부를 만들 수 있는 새로운 수술방법이(관절 치환술등) 더 개발되어 져야할 것으로 생각된다.

Background: The Cox maze-III procedure is considered as the most effective surgical treatment for atrial fibrillation. Because this procedure takes a long time and it complicates the concomitant cardiac surgery, some surgeons perform a left atrial maze procedure or pulmonary vein isolation only to reduce the operation time. This study was performed to evaluate how the modified procedures, with using cut-and-sew techniques, can influence the treatment of atrial fibrillation. Material and Method: Between Feb 1999 and June 2005, 40 patients (17 males and 23 females) with organic heart disease and atrial fibrillation underwent the Cox maze-III procedure (23), the left atrial maze procedure (10) or pulmonary vein isolation (7). The cut-an-sew technique was used to ablate the atrial wall, but cryoablation was used instead of the cut-and-sew technique for the coronary sinus and the inferior wall between the pulmonary vein and the mitral annulus. Result: After a mean follow-up period of $50.0{\pm}21.6$ months, all (100%) of the 23 patients who underwent the Cox maze-III procedure had regular sinus or atrial rhythm conversion, and 7(70%) of 10 with a left atrial maze procedure and 4(57.1%) of 7 with pulmonary vein isolation had regular sinus or atrial rhythm conversion (p=0.002). Conclusion: To obtain a high conversion rate from atrial fibrillation to a regular sinus rhythm or a regular atrial rhythm, the standard Cox maze-III procedure should be performed in both atria. The limited modified procedures like the left atrial maze procedure or pulmonary vein isolation may reduce the cure rate of atrial fibrillation.

Methods: The vision therapy observation included both before and after the surgical correction of intermittent exotropia patients who had binocular vision disorder without opthalmic diseases. Results: According to the results, vision therapy method showed improvement, both case before and after the surgical correction of intermittent exotropia patients. Conclusions: Therefore we suggest that vision therapy is an effective and alternative method for intermittent exotropia patients.

A 6-month old girl who had pulmonary atresia with ventricular septal defect and major aortopulmonary collaterals underwent one-stage complete repair with unifocalization through a bilateral thoracosternotomy(clamshell incision). There were no serious postoperative compli cations, and the postoperative echocardio-graphy showed no residual ventricular septal defect or significant pulmonary artery stenosis. In this condition, great surgical variability exists regarding the sources of pulmonary blood flow. Recent clinical work has focused on a one-stage complete repair. The potential advantages of the clamshell incision are apparent in terms of mediastinal approach, postoperative results, and safety.

Lumbar Sympathectomy is a surgery for plantar hyperhidrosis, vascular and other reflex sympathetic diseases and has a various indications and physiologic effects. However it is not performed actively compared to thoracic sympathectomy because of its invasiveness. Therefore, we tried to perform lumbar sympathectomy using mediastinoscopy with small incision and introduce this new surgical technique. Material and Method: From July 2003 to December 2004, 18 patients undewent lumbar sympathectomy with mediastinoscopy at Inje University Sanggye Paik Hospital. There were 12 males and 6 females whose mean age was 24.3$\pm$8.2 years ranging from 18 to 67 30 cases of lumbar sympathectomy was performed with mediastinoscopy of which 24 cases were for plantar hyperhidrosis and 6 cases for other diseases. Result: Mean operation time was 37.2$\pm$12.5 minutes and mean post operation hospital stay was 3.1$\pm$2.2 days. There was one post sympathetic neuralgia and one peritoneal opening. Conclusion: Lumbar sympathectomy using mediastinoscopy is a simple and effective technique and has the advantage of cosmetics, post operative pain and hospital stay. However, further studies with large number of cases should be carried out for better outcome.

배경: 일차성 자연기흉의 재발방지를 위해서 폐기포절부위에 흡수성 셀룰로스망사와 Fibrin gluefm 도포하여 수술후 재발율을 줄일 수 있는 지 알아보았다. 대상 및 방법: 1996.4우러부터 2000.6월까지 2명의 술자가 222례의 일차성 자연기흉을 수술하였으며, 수술시기와 치료방법에 따라 4군으로 나누어 비교하였다. 제1군은 1996년부터 1997년가지 비디오흉강경수술 및 기계적 늑막유착술로 시술받은 군(25례), 제 2군은 같은 기간동안 액와개흉술 및 늑막유착술로 시술받은 군(53례), 제 3군은 1998년부터 2000.4월까지 흉강경수술 및 늑만유착술로시술받은 군(110례), 제 4군은 1999.7월부터 2000.6월까지 흉강경수술 및 봉합부위를 셀룰로스망사와 Fibrin glue로 보강한 군(34례)이었다. 각 군간, 엑스선상 기흉의 크기 및 폐기포의 수나 크기에 따라 재발율, 공기누출시간 및 흉관지속지간등을 일반선형모델을 사용하여 비교 분석하였다. 결과: 대상환자는 남자 203례, 여자 19례 이었고, 나이는 14게에서 68세이었고, 평균연령은 23.2$\pm$9.6세였다. 재발한 경우는제 1군이 5례(25%), 제 2군이 2례(3.8%), 제 3군이 5례(4.5%)이었고, 제 4군은 재발례가 없었다. 재발례는 모두 수술자의 수술경험이 2년이내일 때 발생하였다. 흉관지속기간은 제 4군이 제 3군(p<0.0006) 및 제1, 제2군(p<0.0001)에 비해서 더 짧았고, 술후 공기누출이 제 4군에서는 없었다. 술전흉부엑스선상 기흉의 크기에 따른 수술후 기흉의 재발울은 경도의 기흉에서 14.3%(2/14)이었고, 중등도 기흉에서 7.4%(10/134)이었으며, 심한 기흉에서는 재발례가 없었다. 재수술한 12례중 봉합부위근처에서 기포가 발행된 경우가 9례(75%)로 많았다. 결론: 재발방지를 위한 시술로 늑막유착술을 시행하지 않고 폐기포절제부위를 흡수성 셀룰로스망사와 Fibrin glue로 덮어주는 시술은 비교적 용이하며, 수술 후 공기 누출이 없었고, 수술 후 흉관지속기간이 더 짧았고, 단기간 추적에서 재발이 없었다. 재발에 영향을 미치는 것으로 흉부엑스선상 기흉의 크기가 작은 경우에는 재발율이 더 높았고, 수술자의 경험이 중요하였다.

In Patients with severe skeletal discrepancy, surgical orthodontic treatment must be accompanied, and recently two jaw surgery has become a common procedure, resulting in improved esthetics and function. Choosing the position of the occlusal plane in this two jaw surgery is an important factor in postoperative stability Therefore this must be taken into consideration during the diagnosis and treatment plan. In this study, among patients with skeletal Class III occlusion, 25 patients(8 male, 17 female, average age $23.2{\pm}3.17$) who have undergone two jaw surgery, setting the ideal occlusal plane according to Delaire's architectural and structural cranial analysis. In comparing preoperative($T_1$). postoperative($T_2$, average of 15.4 days), and long-term postoperative($T_3$, average of 32.6 months) lateral cephalometric radiography, the following conclusions have been made. 1. There were no significant changes of the occlusal plane angle after the two jaw surgery, and there were no significant differences between the surgical technique(SSRO and IVRO). 2. The postoperative changes of the occlusal Plane had no relationship with the amount of jaw movement, amount of posterior impaction, nor the time relapse after surgery. 3. After two jaw surgery, in the SSRO group there was significant forward movement of the mandible, and in the IVRO group the lower incisors extruded as the mandible moved backward and downward which makes the genial angle and the mandibular plane angle significantly increased
