선천성 기관 협착증은 아주 드문 질병이지만 영아나 유소아에 있어서 치명적인 질병이다. 하부기관을 침습한 선천성 기관 협착 환아 2명에게 Peter Goldstraw가 고안한 슬라이드 기법을 이용하여 기관 성형술을 시행하였다. 기관 성형술은 기관 협착부위 중앙을 절단한 후 협착 부위의 상하를 종 절개하여 서로 문합했다. 증례 1은 현재 건강한 상태이다. 증례 2는 술후 4일째 문합부위 파열로 사망하였다. Congenital tracheal stenosis is very rare, but it leads to life threatening obstruction in infancy and childhood. Recently, we experienced two cases of congenital tracheal stenosis, involving half of the distal trachea. We adopted slide tracheoplasty procedure Proposed by Peter Goldstraw Tracheoplasty was performed by dividing the stenosis at midpoint, incising the proximal and distal narrow segments vertically on opposite anterior and posterior surfaces, and sliding these together. On case 1, the patient':s now doing well. On case 2, the patient succumbed due to anastomotic disruption at postoperative ay 4.

Open lung biopsy was performed in thirty patients for the diagnosis and staging evaluation of interstitial lung disease during the period from January 1987 until December 1992. The age of the patients ranged from 14 to 71 years [mean 48 years], and the patients consisted of 14 males and 16 females. Preoperative FEV1`s were from 0.80 liter to 3.88 liters [mean 1.66]. Other non-invasive diagnostic studies such as PCNA, bronchoalveolar lavage, TBLB, and gallium scan were also done in addition to X-ray and high-resolution chest CT. Tweaty-eight were correctly diagnosed and 2 cases were not [diagnostic yield rate 93.3%]. Among the 28 cases,pathologic diagnosis influenced further treatment regimens and prognostic expectations in 23 cases [82.1%]. The diagnostic non-invasive studies other than open lung biopsy yielded a correct diagnosis without staging only in 5 cases. There was no mortality and only one complication, ARDS ; however, the patient recovered after 5 days ventilator support. Open lung biopsy, which is the gold standard for the diagnosis and staging evaluation of interstitial lung disease can be done safely and has value in clinical decision making. Also knowledge of the involvement of the lesion is important for proper selection of the biopsy site.

Increased interest in alternative approach to thoractomy has developed because of the considerable morbidity associated with the standard posterolateral thoracotomy[ST]. Muscle sparing thoracotomy is appeared as excellent alternative because of less postoperative pain and morbidity than standard posterolateral one. Vertical axillary muscle sparing thoracotomy[VM] is the newly revised modified muscle sparing thoracotomy that overcomes the disadvantages of previous lateral muscle sparing thoracotomy such as seroma, cosmetic problems, and need of subcutaneous drains. We conducted a prospective study of 45 consecutive patients to compare postoperative pain, muscle strength of serratus anterior and latissimus dorsi, and range of motion of the shoulder girdle between ST and VM group. There were no difference in preoperative status, surgical procedure, morbidity, mortality and hospital stay between two groups. But there were significant less postoperative narcotics requirements, more preserved latissimus dorsi and serratus anterior muscle strength, nd larger range of motion of shoulder girdle [ especially flexion and internal rotation in VM group. The opening time was prolonged[p<0.01] but closing time was less in VM group [p<0.01]. The sum of opening and closing time was not different in two group. The length of incision line was shorter in VM group. The vertical skin incision was concealed by the upper arm.In conclusion vertical axillary muscle sparing thoracotomy is good alternative for various intrathoracic procedures with less postoperative pain, well preserved muscle strength,increased range of motion of the shoulder girdle and impressive cosmetic outcome.

We reported a successful right pneumonectomy using video assisted thoracoscopy for endobronchial tuberculosis. Thoracoscopic surgery has many advantages in spite of its technical difficulties. These advantages include good cosmetic effects, short hospital stay, decreased postoperative morbidity, and good postoperative pulmonary function.The patient was young unmarried female, and her right lung was nearly total obstructed by endobronchial tuberculous dissemination and secondary pulmonary infection. The procedure was a little complicated by inadequate placements of the thoracoscopic ports and 5cm length utility thoracotomy incision. Minimal pain killer was needed only two days after operation and scar of operative wound was very satisfying. Postoperative course was unusual and the patient was discharged 7 days after operation.

Over the past few years, video-assisted thoracic surgery [VATS] has been used increasingly for intrathoracic pathologic problems as a less invasive operative techniques. Today it is viewed as a sparing and safe alternative to thoracotomy for a wide spectrum of indications. Using video-assisted operative thoracoscopy, we performed consecutive 150 operations on 148 patients during the initial 2 years of our experience from July 1992 with the following indications: pneumothorax [n=53], hyperhidrosis [n=29], mediastinal mass [n=23], pleural disease [n=13], diffuse parenchymal or interstitial lung disease [n=12], benign pulmonary nodule [n=7], metastatic lung mass [n=3], primary lung cancer [n=3], bronchiectasis [n=2], malignant pericardial effusion [n=2], endobronchial tuberculosis [n=1], esophageal achalasia [n=1], and pulmonary parenchymal foreign body [n=1]. There were no death, and overall complicaton rate was 24.0%[n=36]. The most prevalent complication was persistent air leakage [longer than 5 days] in 14 cases [9.3%]. Persistent pleural effusion [longer than 5 days] occurred in 6 cases [4.0%]. Six patients were converted to an open thoracotomy because of inability to control the operative bleeding [n=3], failed adhesiolysis in bronchiectasis [n=2], and radical excision of an lung cancer [n=1]. Pneumothorax recurred in 3 cases[2.0%]. Other complications were Horner`s syndrome, diaphragm tears, temporary phrenic nerve palsy, hoarseness, subsegmental atelectasis, transient respiratory difficulty, and esophageal mucosal tear. The advantages of this minimally traumatizing operative technique lie in improved visualization, decreased pain, shortened hospital stay, and less postoperative morbidity. The indications of VATS has been extended increasingly to intrathoracic pathologies, but its role in the managements of primary lung cancer and esophageal disease remains to be defined.

Hyperhidrosis, one of the abnormalities in autonomic nervous system, has been treated with dermatologic principles or thoracic sympathectomy via conventional axillary thoracotomy or dorsal spinal approach. But these techniques were rather ineffective or invasive. Recently, VATS is widely applied in thoracic surgical area, and hyperhidrosis is not the exception of these cases.From May 1993 to August 1994, 30 patients with bilateral palmar hyperhidrosis underwent bilateral thoracic [T2, T3 sympathectomy with thoracoscopic surgery at Seoul National University Hospital. There were 20 men and 10 women and the mean age was 23.0 years.Mean operating time was 115 min and there was no thoracotomy conversion. Operative complications were anesthetic overdose in 1, Horner`s syndrome in 1, and small amount of residual pneumothorax in 6. Mean postoperative hospital stay was 2.3 days [range from 1 to 4 days and postoperative analgesics were required in 17 cases with a single dose.Sweating amount was measured in 12 patients, showing significantly decreased amount from 284.5 mg preoperatively to 18.9 mg postoperatively in 5 minutes [p=0.004 . There was no recurrence during mean 6 months follow up. Twenty two patients [73.3 % complained moderate compensatory hyperhidrosis on the trunk.In conclusion, all patients were greatly satisfied with those results including no more palmar sweating, less pain, better cosmetics, short hospital stay. In addition, recent use of sweating amount measurement and intraoperative temperature monitoring could make this technique more accurate, so we easily applied thoracoscopic sympathectomy with minimal risk.

Airway obstruction may be caused by extreme mediastinal shift and rotation after right pneumonecotmy or after left pneumonecotomy in the presence of right aortic arch.We experienced such a complication after right pneumonectomy, so called right postpneumonectomy syndrome. The patient was 28 years old female, and 4 month ago she had undergone right pneumonecotomy via video assisted thoracoscopic surgery[VATS] for endobronchial tuberculus dissemination and secondary pulmonary infection. She was treated by mediastinal repositioning which were composed of substernal fixation of pericardium and insertion of expandable prosthesis of 1000 cc capacity. She had good postoperative course and now she feels no obstructive symptoms.

광범위한 기관의 병변시 동종이식 편을 이용한 기관 대치 술이나 폐 이식술시 공여 기관 및 기관지의 허혈 은 심각한 문제로서 공여 기관의 궤양 및 협착, 문합부위의 치유장애로 인한 문합부위의 분리로 나타나게 된다. 이러한 공여 기관의 허혈을 방지하기 위하여 여러 연구가 있어 왔으며 현재는 대망 성형술 및 여러 종류의 성장인자가 각광을 받고 있다. 이번 연구에서는 대망 성형술 및 염기 섬유아세포 성장인자가 허혈 에 빠진 공여 기관의 혈관 재형성 및 상피세포 재생에 어느만큼 기여하는지 조사하였다. 약 2cm정도의 토끼 경부 기판을 완전히 절제한 후 다시 연결해 주는 자가 이식을 시행한 군, 자가 이식 및 대망 성형술을 시행한 군, 자가 이식'및 1 us의 염기 섬 유아세포 성장인자를 도포한 군의 3군으로 나누 었다. 각각 술후 3일과 7일 그리고 14일 후에 99m Technetium이 부착된 인혈청 알부민의 흡수 정도를 측정하였고 병리조직학적 검사를 시행하여 상피세포의 재생 정도를 관찰하였다. 술후 3일째 99m Technetium 흡수정도로 측정한 혈관 재형성 정도에 있어서 염기 섬 유아세포 성장인자를 도포한 군에서 다른 두군에 비해 통계학적으로 \ulcorner의하게 혈관 재형성이 좋았다(p<0.05). 그러나 술후 7일째 및 14일째 측정한 결과는 세군 간에 차이가 없었다(p>0.05). 술후 3일과 7일에 측정한 상피세포 재생정도 에 있어서도 염기 섬 유아세포 성장인자를 도포한 군에서 통계학적으로 유의하게 다른 두군에서보다 좋았다(p<0.05). 그러나 술후 14일째 검사한 상피세포 재생정도에 있어서는 세군 간에 차이가 없었다. 결론적으로 국소적인 염기 섬 유아세포 성장인자의 도포는 허혈에 빠진 공며 기관의 혈관 재형성 및 상피 세포 재생을 촉진시키는 것을 알 수 있었으며 특히 초기에 허혈에 빠진 공여기관의 혈관재형성을 촉진시킨다는 것을 알 수 있었다. Donor airway ischemia is a significant problem after tracheal replacement with homograft or lung transplantation, Several factors such as omentopexy, heparin, PGl2 and fibroblast growth factor, have been shown to induce angiogenesis in vitro and in vivo. This study was designed to investigate whether omentopexy and basic flbroblast growth factor can enhance rabbit tracheal revascularization and epithelial regeneration, Three different experiments were performed with New Zealand white rabbit. In group I(n= 15 control group), only coNical tracheal autotransplantation was done. In group II(n= 15), cervical tracheal autotransplantation with omentopexy was done through subcutaneous route. In group III(n= 15), cervical tracheal autotransplantation was done and lug basic flbroblast growth factor was applied. After 3, 7 and 14 days, the animals were sacrificed. The extent of revascularization was investigated by means of uptake of the human serum albumin labelled with 99m technetium, and epithelial regeneration were assessed by means of light microscope. In the group investigated at day 3, there was statistically significant high tracheal revascularization in group III(p<0.05), but no difference at 7 and 14 days. And epithelial regenerations at day 3 were better in group III(p<0.05), and at day 7 in group II and III. But there was no difference at day 14. We concluded that b-FGF can enhance the revascularization and epithelial regeneration of the tracheal autograft especially in early phase.

심실중격결손증에서 수술전 혈류역학치가 수술후 폐동맥압력에 미치는 영향

성숙환 대한흉부심장혈관외과학회 1986 Journal of Chest Surgery (J Chest Surg) Vol.19 No.2

The prognosis of patients with VSD and pulmonary hypertension is at least partially related to the reversibility of pulmonary hypertension after surgery. To predict postoperative pulmonary arterial pressure, immediate postbypass values were compared with preoperative hemodynamic data in 18 surgically closed VSD patients aged 6 to 80 months. The following results were obtained. 2] There was a good correlation between preoperative PP/PS and postoperative PP/PS in patients aged over 24 months [r=0.685, p<0.05], and in patients whose QP/QS were over 2.0 [r=0.686, p<0.01]. 3] There was also a good correlation between pump time and postoperative PP in total patients [r=0.697, p<0.005]. 4] Direct correlations were found between preoperative PP/PS and immediate postbypass PP/PS in patients aged over 24 months and in patients whose QP/QS>2.0, but the effect of CPB would participate in some degree. So it may be necessary to reevaluate their relationship after the effect of CPB have been disappeared.
