There are more patients with tracheal stenosis lately due to the increased use of tracheostomy and assisted ventilation. Recently we have experienced two cases of post tracheostomy tracheal stenosis and successfully performed circumferential resection and end-to-end anastomosis of the trachea. Postoperative tracheostomy was not performed. The postoperative courses were uneventful and they are now conducting an usual life.

Sudden esophageal obstruction by a bolus of food is not a rare phenomenon. The individual is frequently elderly and has ill-fitting dentures through others may initiate this by bolting food. In adult patient there is a frequent history of alcoholic intake, the consumption of meat with improper chewing. A common anatomic abnormality leading to meat impaction of the esophagus is hiatal hernia, which is often associated with a ring or stricture. Recently authors experienced a case of repeated esophageal foreign bodies in 10 days in the patient who had esophageal stricture.

The most common cause of the decannulation difficulty is the trauma. This may be accidental, iatrogenic such as prolonged intubation, high tracheostomy, secondary infection, formation of granulation tissue, improper use of cannula and wide resection of anterior tracheal wall. Another common cause is psychologic dependency. Treatments may be categorized into dilatation with or without injection of steroid, dilatation and prolonged stent, luminal augmentation and resection of the stenosis with primary reanastomosis. Recently authors experienced a case of the decannulation difficulty in a 2 - year - old which was developed after tracheostomy for the removal of bronchial foreign body and was treated with a silicon T -tube stent with good result.

With the improvement of living standard and socioenvironmental change, esophageal stricture due to acetic acid, Hcl, insecticides and lye has led to decrease remarkably. Esophageal stricture has decreased because of immediate treatment and adequate management. However there are still sporadic incidents of esophageal stricture due to inadequate treatment and uncooperation of patients. The authors recently have experienced seven severe cases of esophageal stricture. All six patients were treated with 18-51 French Sippy esophageal dilating bougie. One patient was transfered to thoracic surgery department due to complete esophageal obstruction. Case 1. A 23 year old housewife who ingested Hcl for suicide. After Witzel's operation, she visited to dilate esophageal first constriction stircture due to swallowing difficulty postoperation 2 months later. We were treated successfully. Case 2. A case of esophageal stricuture in the second and third physiologic constriction part. The patient was 51 years old man who ingested lye accidently, and was dilated by bougination. Case 3. The patient was 43 year-old man who ingested acetic acid as a mistake and was treated inadequately at hopsital. Inspite of treatment, esophageal stricture developed at the third physiologic part. We are trying to dilate the esophagues now. Case 4. The patient was 55 year-old woman who had ingested Hcl for the purpose of suicidal attempt. 2 months later gastroduodenal anastomoisis due to pyloric region stenosis, the first physiologic constriction stricture was dilated successfully. Case 5. The patient was 41 year-old woman who ingested Hcl for suicide 4 months ago. There was indwelled orogastric tube for 1 month but esophageal stricture developed at the first and 3rd constriction part. She was treated by using a bougination. Case 6. An athlete 21 year old man, ingested acetic acid 2 spoonful per 3 days by purpose in order to soften the bone for last 14 months. There was complete esophageal obsturction in esophagogram and transferred to the thoracic surgery department. Case 7. A 3 year-old girl was ingested lye at a accident. She had a bougination for 16 months under the general anesthesia for dilation due to whole irregular esophageal stricture. She developed lower esophageal perforation, but healed eventually.

In recent years there has been considerable interest in reconstructive surgery of the trachea for cervical tracheal stenosis developed by complication of endotracheal intubation or tracheotomy, or trauma of the neck. The methods used to reconstruct the tracheal defects can be repaired with end-to - end anastomosis, cervical flaps, and autogenous graft materials. Since Grillo had undertaken tracheal reconstruction after circumferential resection in dogs, resection and end - to - end anastomosis was used in cases of circumferential stenosis. And, costal, nasal septal and auricular cartilage have been used for the autogenous graft materials. Since Caputo and Consiglio had undergone tracheoplasty with auricular cartilage, Morgenstein reported successful repair of a tracheal defect with a composite postauricular cartilage graft. The advantages of the auricular cartilage graft are its easy accessibility, availability and familiarity to the otolaryngologist. In past 2 years, We performed the tracheoplasty with auricular cartilage graft and end- to end an astomosis after segmental resection in 5 patients who had suffered from tracheal stenosis. And we obtained good results. So, we reported the cases with review of the literatures.

연구배경: 수술적 치료가 필요한 척추관 협착증 환자들은 주로 60세 이상의 고령환자로 장기간의 입원 시 기회 감염의 증대와 불필요한 의료비의 증대를 가져오게 되며, 수술 후 환자들의 재원일수의 증가는 병원의 병상가동률을 감소시키고, 전공의에게는 불필요한 업무를 증가시킨다. 연구목적: 비용 효과면에서 최적화된 진료 지침의 개발은 불필요한 의료비의 감소 및 Hospital Induced Complication을 줄여 환자 만족도를 증진시킬 수 있으며, 각 환자에 대한 전공의 업무를 줄일 수 있다. 의료기관: 서울특별시에 소재한 2,075병상의 종합전문요양기관 연구방법: 정형외과 및 신경외과의 척추관 협착증 환자의 처방을 비교하여 최적의 표준진료지침을 개발하고 최종적으로 CP Master Program(EMR 프로그램)에 입력하여 환자에게 적용하였다. 연구결과: CP 적용 전, 후 비교를 통해 재원일수는 3.8일이 감소하였으며, 이에 따라 병상 가동률 및 진료수익이 증가했으리라고 예상되며 현재 비교 검토 중이다. 또한, CP 개발 및 CP Master Program의 사용을 통한 전공의 업무 감소에 대해 검토하고 있다.

Surgery on the distal trachea or the carina presents special problems for maintaining the airway and systemic oxygenation. Cardiopulmonary bypass is an alternative method for respiratory support for the patients with these conditions. Percutaneous cardiopulmonary support (PCPS) applied under local anesthesia has recently been used for respiratory support in tracheal surgery and the outcome is satisfactory. We encountered a patient who had severe distal tracheal stenosis after prolonged intubation. We had a gratifying result with performing tracheal resection and repair under the support of PCPS.

Purpose : In adults, endoscopic tracheobronchial balloon dilatation and stenting have become valuable methods to establish and maintain an adequate airway lumen when tracheomalacia or neoplastic growth compromise the airways. But in children, only a few cases were reported due to technical problems. We report six children who were treated with stent implantation and describe the use and safety of airway stents. Methods : Six patients with severe airway obstruction were treated. We investigated the underlying medical problems, stenotic site, symptomatic improvement and complications, and the size and location of stent. Results : The median age of the six patients was 21 months. Three of them were mechanically ventilated and one had an endotracheal tube to maintain the patency of airway. Diagnoses were : congenital tracheal stenosis with or without bronchomalacia, granulation tissue formation after right upper lobectomy by bronchial carcinoid or after prolonged intubation, endobronchial tuberculosis, and airway compression by mediastinal undifferentiated sarcoma. Nitinol stents were implanted in the airway guided by bronchoscopy and fluoroscopy simultaneously. Three cases were placed in trachea, the others were in the bronchus. After stent implantation, all patients showed marked improvements of their airway obstructive symptoms. Four patients are doing well, although two expired due to underlying diseases. Four patients had granulation tissue formation around stents, but that was tolerable after removing the stent. Conclusion : We suggest that the use of expandible metallic stent implantation can offer safe therapeutic option even in extremely severe, life threatening and inoperable airway stenosis in children.
