Although there are many kinds of method in treatment of tracheal stenosis, tracheal resection and primary anastomosis can be performed for management of various kinds of tracheal stenosis because it is considered the most anatomical ideal therapeutic modality. During a 10-year period we performed 18 tracheal resection on 18 patients with no operative mortality and some morbidity. 13 patients had tracheal stenosis caused by endotracheal intubation [eight patients or tracheostomy [five patients ; and five patients caused by a variety of neoplastic lesions [four primary and one secondary . The length of tracheal stenosis were various from 1.5cm to 5.5cm and site of tracheal stenosis were cervical[17patients and thoracic [one patient . Operative techniques were tracheal resection and primary anastomosis[18 patients and additional procedures were cricoid cartilage reconstruction with costal cartilage [one patient , primary repair of esophagus[one patient and suprahyoid laryngeal release technique[eight patients without any complications. We have eight complications; tracheal restenosis were developed in five patients[growth of grannulation tissue at anastomotic site in three patients, delayed restenosis in two patients , anastomotic disruption in one patient, hoarseness and pneumonia in each of two patients. We managed tracheal complications with T-tube insertion in two patients, permanent tracheostomy in three patients and insertion of Gianturco tracheal stent in one patient, but tracheal stent did not reveal good result because it caused persistent production of sputum. We concluded that it is necessary to access full length of normal trachea including suprahyoid laryngeal release technique to avoid anastomotic tension in tracheal surgery and develope new ideal techniques to manage postoperative tracheal complications, because we suppose tracheal complications are developed due to anastomotic tension.

Background and Objectives : The aim of the this study is to determine the efficacy of an external prosthesis made of ringed Polytetrafluoroethylene to prevent Postanastomotic stenosis after surgical correction of extensive tracheal defects in rabbits. Materials and Methods : Thirty rabbits were used, divided into two groups of 15 animals each. Group A rabbits underwent resection of six-ring segments of the cervical trachea and tracheal end-to-end anastomosis. The Procedure used in group B was similar to that used in group A. but the tracheal anastomosis was supported by an external ringed polytetrafluoroethylene prosthesis. After six months, rabbits were killed and tracheas were resected and then compared the postanastomotic tracheal stenosis using morphometry. Results : Anteroposterior diameter, transverse diameter, cross sectional area and intra luminal perimeter of trachea was greater in group B than group A. Also inflammatory changes of mucosa and submucosa were greater in group A than group B. Conclusion : A ringed PTFE as a external stent was effective to prevent tracheal stenosis resulting from the extensive tracheal resection and tracheal reconstruction in rabbits.

Three-dimensional reconstruction of computed tomographic image(3D CT) is a well-established imaging modality which has been investigated in various clinical settings. It is commonly performed in case of congenital or developmental abnormalities, and traumatic fracture of skull and face that requires reconstruction of osseous structure. However reporting the 3D CT in laryngeal or tracheal stenosis is rare and its results are obscure. The authors performed 3D CT in six cases of tracheal stenosis and found diagnostic value of 3D CT. A Comparision of diagnostic information obtained from plain X-ray, 2D CT and 3D CT has performed in total six cases of tracheal stenosis. Surgical treatment of the tracheal stenosis was following in these cases : tracheal end to end anastomosis In 1 case, laryngotracheal end to end anastomosis in 2 cases. 3D CT information was compared with operative finding. In two of six cases, satisfactory information was not obtained from 3D CT in evaluating an exact stenosis of trachea. Future, it will be helped in evaluating of tracheal stenosis by 3D CT.

We experienced 5 cases of tracheal stenosis and 7 cases bronchial stenosis treated surgically at the Department of Thoracic and Cardiovascular Surgery, School of Medicine, Hanyang University during 5 years. The causes of tracheal stenosis were prolonged endotracheal intubation 1 case, tracheostomy 1 case, the sequela of endobronchial tuberculosis 2 cases and tracheomalacia 1 case. The causes of bronchial stenosis were all endobronchial tuberculosis. The managements of tracheal stenosis were tracheal resection and end to end anastomosis. The resected lengths of trachea were 1.5cm, 3cm and 7.5cm. One case of suglottic stenosis was underwent the resection of trachea, 8cm in length, and the laryngotracheal anastomosis was done, but the re-stenosis of trachea was developed after 4 weeks post-operatively. One case of tracheomalacia was done permanent tracheostomy only, because the entire trachea was adhered to the surrounding tissue. The managements of bronchial stenosis were resection of involved lobe or one lung, in the 5 case. One case with Lt. main bronchial stenosis and atelectasis of Lt. upper lobe was done the lobectomy of Lt. upper lobe only and then, the Lt. pneumonectomy was done re-operatively because the atelectasis of Lt. lower lobe had continued. The other one case with stenosis of Rt. main bronchus, failed the insertion of metalic stent, was underwent the Rt. upper lobe lobectomy, sleeve resection and side to end anastomosis

Despite improvement in respiratory care, including widespread use of low pressure and high volume cuffed tubes, tracheal stenosis remains a feared complication of prolonged intubation and tracheostomy. In such patients, other coexisting problems such as vocal cord paralysis, tracheoesophageal fistula, noncontiguous stenotic segments and laryngeal stenosis may occasionly be encountered. Therefore tracheal stenosis still presents a significant management problem, despite recent endoscopic advances and surgical techniques. Between 1991 and 1994, authors preformed tracheal resection with end-to-end anastomosis on 11 patients with tracheal stenosis. The total success rate (asymptomatic patients with patent airway) was 72.7% and there were no serious complication. This report reviews our experience about this procedure and surgical results. And it investigates associated factors for successful results.

배경; 기관 협착의 가장 흔한 원인은 기관 삽관에 따른 합병증이다. 기관 협착에 대한 치료 방침은 병변의 범위에 따라 달라진다. 전막부분의 국소적인 병변의 경우에는 레이저 절제요법을 적용할 수 있지만, 기관의 전층에 병변이 있는 경우는 기관 절제 후 단단 문합 수술을 시행하여야 좋은 치료 결과를 얻을 수 있다. 대상 및 방법; 경상대학교병원 흉부외과에서는 1998년 4월부터 1999년 5월까지 기관 삽관의 합병증으로 발생한 기관협착증 환자 12명에게 기관협착부위를 절제하고 단단 문합 수술을 시행하였다. 결과; 수술 후 사망자는 없었고, 조기 합병증으로 일시적인 성대마비가 5명, 창상 감염이 1명에서 발생하였다. 수술 후 평균 18개월간 추적하는 동안 재협착은 발견되지 않았다. 결론; 기관 삽관 후 발생한 기관협착증에 대한 외과적 치료로서 절제 및 단단 문합술은 비교적 우수한 치료버빙라 할 수 있다.

소아의 기관협착은 대부분이 장기간의 기관내삽관에 의해 초래되며 그 치료방법은 기관 협착의 정도 및 부위에 따라 다르다. 협착의 정도가 경하고 주로 육아조직에 의한 경우는 반복적인 내시경적인 처치만으로도 치유가 되지만 협착부위가 광범위하거나 정도가 심한 경우는 수술적인 기관재건이 필요하게 된다. 저자들은 이러한 기관재건술로 윤상갑상연골절제 및 연골이식, 그리고 협착부절제 및 단단문합의 방법 등을 현재까지 사용하였으며 괄목할 만한 결과를 얻었다. 저자들은 지금까지 경험한 9 명의 소아 기관협착 환자에서의 단단문합술에 의한 치험과 단단문합술의 적응증을 제시하고자 한다.

A 37 year old male patient was suffered from severe labored breathing caused by post tracheostomy stenosis, which was localized at the mediastinal trachea [cuffed tracheal stenosis] and ranged 1.5 cm in length and approximately 3 ram. in diameter on tracheogram. After dilation of tracheal stenosis with dilator, endotracheal intubation was tried for induction of anesthesia and control of respiration during operation. A tube was placed just beyond the tracheal stenosis without respiratory difficulty. Under the endotracheal anesthesia, circumferential resection of the mediastinal trachea containing the stenosis, approximately 2 cm in length [4 tracheal rings}, was carried out and primary direct end to end anastomosis was performed with interrupted submucosal sutures [3-0 Dexon] and mobilization of trachea Postoperative tracheostomy was not performed. The patient was completely relieved from dyspnea immediately after operation. Post-operative convalescence was entirely uneventful and at present, about 3 months after operation, he is now conducting a usual life. From the literature and our experience, the etiology and treatment of post-tracheostomy stenosis were discussed.

Resection and reconstruction of distal trachea or carina have posed tremendous technical challenges for surgeons. Successful outcome depends on thorough preoperative evaluation, careful anesthetic management,strict attention of surgical technique and postoperative care. We report a successful case of revision of tracheal stenosis using femoro-femoral bypass on a 13~year-old boy. The patient complained severe dyspnea about I month following right sleeve pneumonectomy. Preoperative CT scan and intraoperative bronchoscopy showed pin-point tracheal stenosis at a tracheo-bronchial anastomosis site about 1.2cm in length.At operation the lesion was severely adhesed and the lumen was nearly obstructed. The stenotic segment was resected and direct end-to-end anastomosis was done under femoro-femoral bypass for adequate oxygenation. The patient was discharged at postop. 16 days without specific complications and has continued to do well.
