This is the result of the annual statistic analysis of thoracic and cardiovascular surgical cases in 1991, Korea. 14,715 cases of surgery[thoracic 8,995/cardiovascular 5,720] were done by 53 institutes replied. The order of frequency of cell type in primary lung cancer was squamous [62.3%] / adeno [23.9%] / small [6.4%] / adenosquamous [3.0%], and in mediastinal tumor, neurogenic[27.l%] / thymoma [27.1%] / teratoma[26.4%] / congenital cystic[12.0%]. Surgery for tuberculosis was decreased to 15.8% of overall infectious disease from the recent 6 year`s average 35.7%. In general thoracic surgery, the single most frequent operation was closed thoracostomy[4,047 cases] for pleural pathology. The ratio of congenital to acquired heart disease was 2:1, and acyanotic to cyanotic was 3:1. The order of frequency of congenital acyanotic heart disease was VSD [45.6%] / ASD [25.6%] / PDA [20.4%] / PS [2.9%], and that of cyanotic heart disease was TOF [42.6%] / PA [12.9%] / TGA [9.9%] / DORV [8.8%]. In 1,364 cases of valvular surgery, single mitral pathology was the most frequent candidate[729 cases, 53.4%]. In 243 cases of coronary surgery, bypassing graft materials were great saphenous vein[41.6%], internal mammary [39.5%], and artificial vessel[18.9%]. There were no specific differences in aortic surgery, assisted device implantation, and antiarrhythmic surgery as compared to previous study. This nation-wide inquiry will be continued and reported annually by KTCS Society.

Background: Cardiac involvement of Behcets disease is very rate, however, the prognosis of Behcet disease depends on cardiovascular complications. In this article, we described surgical treatment of aortic insufficiency with Behcets disease. Material and Method: From March 1986 to February 1998, we operated on 10 patients of aortic insufficiency with Behcets disease. Male to female ratio was 8 to 2, and age ranged from 21 to 40 years(mean 32.8 years). There were 8 patients with evidence of Behcets disease and another 2 patients had some suspicious findings of Behcets disease(i.e., prosthetic value dehiscence, hypertrophied aortic wall). Adequate preoperative medical treatment for Behcets disease was done in 3 patients. Result: We performed 24 open heart surgeries in 10 patients. Redo value replacements using prosthetic valves were done in 4 patients. Among them, 2 patients were operated on for a second redo valve replacement and one of them operated on for a 4th and 5th operation because of recurrent paravalvular leakage. These 4 patients expired. 1 patient who had undergons tissue value replacement is alive. 1 patient who underwent Cabrol operation expired dut to rupture of graft anastomosis site. We used homografts in 3 patients. In 2 of them, we performed aortic root replacement and subcoronary valve replacement in another patient. The patient who underwent subcoronary valve insertion had remnant aortic insufficiency, so we are closely observing him. We also performed Ross operation in a 24 year old female who suffered severs aortic insufficiency and endocarditis after aortic valvuloplasty. 5 patients are alive and mean follow up duration is 49.0 months. Among them, we used homografts or sutografts in 4 patients. We could observe excellent clinical results in the patients who underwent aortic root replacement using homograft and they were treated medically for Behcets disease. Conclusion: We concluded that adequate preporative diagnosis, clinical suspicion, and periopertive medical treatment for Behcets disease are very important for the result of surgical management of aortic insufficiency with Behcets disease. The use of homograft or autograft was helpful for the healing of anastomosis site and we should carefully observe the long term follow up results.

Forty cases of coronary artery bypass grafting treated at the Department of Thoracic and Cardiovascular Surgery, SNUH, Korea were compared with forty cases of the procedure treated at University of Alberta Hospital, Canada, in terms of pathoanatomy. That showed no difference in sex ratio between Korean and Caucasian the average ages, however, were 50.4 years and 60.9 years respectively [p< 0.005]. The leading cause of angina at presentation was unstable angina in Korean, but it was post-infarction angina in Caucasian instead. The incidences of single-vessel disease and double-vessel disease were similar in both countries, but the incidence of so-called triple-vessel disease was higher in Caucasian while left main coronary artery disease was more prevalent in Korean [0.01< P, 0.005]. < The internal diameters of surgically available coronary artery branches had similar characteristics and no significant statistical differences were found between them. The predilection sites of stenoses were proximal left anterior descending artery, left main coronary artery, proximal left circumflex artery and proximal right coronary artery decreasing in incidence respectively, in Korean. The myocardial perfusion score were 6.80 in single-vessel disease, 7.56 in double-vessel disease, 11.27 in triple-vessel disease and 9.77 in left main disease respectively, in Korean.

Overall 25,095 cases of general thoracic surgery were analysed, which were performed by 48 institutes in Korea during recent 6 years[242 hospital-years]. The proportions of tumorous disease and infectious disease to be operated were 6,864 cases[27.4%] and 6,775 cases [27.0%], The most common organ involved for operation was lung-bronchus 16,542 cases [69.5%], and remainders were pleura 2,500 [10.0%], esophagus 2,433[9.7%], mediastinum 1,902[7.6%], chest wall 1,297 [5.2%], and diaphragm 421 [1.7%] in order. Among 6,864 cases of tumorous diseases, the most common causes for operation were lung-bronchus tumor 3132 cases [45.6%] and most of them were lung cancer 2,731 cases [88.7%]. In the 2,019 cases of primary lung cancer with known cell type, squamous cell carcinoma 1,296 cases [64.2%] and adenocarcinoma 460 cases [22.8%] were the most. The common types in the 1,207 cases of mediastinal tumor with known cell type were neurogenic tumor 348 cases [28.8%], thymoma 311 [25.8%], and teratoma 252[20.9%]. The annual cases of operation for tumorous disease including malignant tumor were increased steadily. Operation for infectious lung diseases [including bronchiectasis and tuberculosis] were about twice common than infectious pleural disease [i.e. empyema], and operations for tuberculous disease occupied about half cases of infectious lung disease. In 11,456 cases of other disease entities, excluding tumorous and infectious disease, there were bullous lung disease 9,074 cases[79.2%], benign esophageal disease 484[4.2%], myasthenia gravis 356[3.1%], chest wall deformity 483[4.2%], and diaphragmatic lesion 421[3. 7%] in order. We propose that above results for inquiry can be used as the basic data of general thoracic surgery in Korea.

Cardiac surgery in neonates with congenital heart disease has progressed dramatically in the past three decades. However, low-birth-weight neonates with congenital heart disease continue to challenge the intellectual and technical skills of healthcare professionals. We present a case of a low-birth-weight neonate with pulmonary atresia and a ventricular septal defect, in whom palliation was achieved with a right ventricular outflow tract stent using a hybrid procedure.

Obstructive intracardiac lesions, like mitral stenosis or insufficiency (MR), by myxomas of the left atrium have been commonly reported, but the attenuation of MR by myxoma combined with coronary artery disease is very rare. We report a 70-year-old female patient whose left atrial myxoma had attenuated moderate MR to mild MR and required mitral valve surgery after removal of the myxoma. She also had coronary artery disease, severe pulmonary hypertension and moderate tricuspid regurgitation due to the mitral valve lesions obstructed by myxoma. The patient underwent removal of myxoma, mitral and tricuspid valve reconstructions, and coronary artery bypass grafting. She was discharged at the postoperative 14 day without any problems.

The purpose of this study was to examine the relation between thoracic scoliosis and gastroenteric disorder. In this article, We surveyed sixty two patients and investigated through a questionnaire the health and meal habits, digestive trouble levels, stress levels(BEPSI-K), and the stress response index(SRI). Participants were classified according to each group in over $10^{\circ}$(vertebral scoliosis), under $10^{\circ}$(functional scoliosis) and made a diagnosis of X-ray of scoliosis grade. The data was took statistics on two group by independent t-test, chi-square test with SPSS/PC+ 10.0 program. The statistically significance was a p＜.05 and the following results were obtained； 1. In general characteristics, The thoracic scoliosis was as many as women, weight 50∼60kg, height 160∼170cm, married person. 2. Relations between health and meal habit with thoracic scoliosis was not statistically significant(p＞.05). 3. Relations between thoracic scoliosis and digestive trouble level was statistically significance (p＜.05). 4. Relations between thoracic scoliosis and incidence rate of internal disease was statistically significant(p＜.05). 5. Relations between thoracic scoliosis and stress(BEPSI-K) was statistically significant(p＜.05). 6. Relations between thoracic scoliosis and stress(SRI) was statistically significant(p＜.05). These results lead us to the conclusion that thoracic scoliosis influences digestive trouble, incidence rate of internal disease and stress. However, there results are not easy to explain because of the limitations of a few subjects and a single comparison. Therefore, further research on this study thoroughgoing inspection would clarify the association of thoracic scoliosis and gastroenteric disorders.

Thoracic extramedullary hematopoiesis (EMH) is a rare disease entity that is usually associated with hematologic disorders, such as myelodysplastic or hemolytic disease. Because thoracic EMH is usually encountered as a mass during radiologic examinations, it should be differentiated from posterior mediastinal neurogenic tumors. Here, the authors report a case of EMH associated with hereditary spherocytosis. The patient underwent a complete excision by thoracoscopic surgery to differentiate it from other mediastinal tumors.
