Previously, we used a rigid bronchoscope in removal of endotracheal granulation tissue and foreign body. But these method has poor visual field and difficulty in handling of the instruments, therefore there were restriction in removing the endotracheal granulation tissue and foreign body. Recently we underwent one case each of endotracheal granulation tissue and foreign body causing dyspnea and removed them by right angled forceps under visualization via nasal rigid endoscope inserted through the tracheal stoma. We suggest this method for removal of tracheal foreign body, granulation tissue and excision of tumorous condition in patients with tracheocutaneous fistula.

Increasing success in the management of patients with severe respiratory failure by mechanical respirators has produced iatrogenic tracheal stenosis. And the surgical management of these lesions have provided a major field for tracheal reconstructive surgery. Recently we have experienced three cases of postintubation tracheal stenosis between December, 1985 and October, 1987 and successfully performed circumferential resection and end to end anastomosis of the trachea. The lesion of the first case which was located in the subcricoid level was resected about 2cm length with cervical incision. And the lesion of the second case located at the cuff site was also resected about 2.5cm length with cervical and median sternotomy incision. Also the lesion of the third case located at the stoma site was resected about 1.8cm length with cervical incision. The postoperative courses were uneventful but there was extubation difficulty in the third case because of stupor mentality and problem of secretion excretion. So we have observed the postoperative course after T-tube insertion.

문명의 발달로 나날히 복잡해지는 사회 환경속에서 우리는 생명을 위협하는 수 많은 사고를 당하게 되며, 이럭 경우에 상기도를 유지하기 위한 기관절재술을 많이 시행하게 되는데, 때로는 기관협착등 이에 따른 여러가지 합병증을 유발하게 되는 경우가 있으며, 임상가들에게도 곤란한 문제를 갖어다 주고있다. 그러나 이러한 합병증은 수술방법의 개선과 항생제의 출현등으로 그 빈도가 많이 감소되기는 하였으나, 1969년 Lindholm은 술후성 기관협착증의 빈도를 1.5%내지 10%라고 했으며, 1969년 Donnelly, Mulder와 Rubush, 그리고 1971년 Andrew와 Pearson 등은 이들 원인의 대부분이 cuff 가 있는 기관삽입관이나, 기관케뉼(tracheal canula)의 부적합한 사용이나, 또는 감염에 의한 압박괴사(pressure necrosis)로 형성된다고 하였고, 협착부위로서 1972년 Bryce는 절개공(stoma)주위가 가장 많으며, 응급기관절개술시에 의사의 부정요법(mal-practice)도 원인이 될 수 있다고도 주의한 바 있다. 기관협착증의 치료로서 협착이 경미한 경우에는 일차적으로 세심한 관찰을 실시하면서 실리콘관(silicon tube)이나 스텐트(stent)를 사용하거나, 비강을 통한 삽관법(naso tracheal intubation)으로 기계적인 확장을 시도하며 (Schmiegelow, 1929, Montgomery, 1965), 육아조직이 형성되었을 경우에는 기관경검사하에서 이를 제거한 후에 steroid를 병용하는 편이 좋은데(Birck, 1970) 그밖에도 기관개찰술(Fenestration method, 백·홍 1974)이나 재수술(Revision)을 하기도 한다. 이러한 방법으로서도 치료가 불가능한 경우에는 그 협착 부분을 절제한 후에 단단문합술(End-to-End Anasto-mosis)을 시행하는 수도 있다. 저자들은 1967년 10월부터 1977년 3월까지 10연년간 세브란스병원에서 기관절개술을 받았던 1514례를 대상으로 일련의 조사를 실시하여 이들 중에서 기관협착증을 유발한 23례를 치료하였으며, 여기서 몇가지 지견을 얻었기에 보고하는 바이다.

A total of 55 patients underwent surgical managements for postintubation tracheal stenosis from July 1975 through March 1997. All but 8 had received ventilatory assistance. The patients had S cuff lesions, 17 stoma lesions, 7 at both levels, 5 at subglottic lesions. Thirty two patients underwent the sleeve tracheal resection and end-to-end anastomosis. Five patients performed a wedge resection and end-to-end anastomosis. Twenty two patients received the Montgomery T-tube for relief of airway obstruction. Simple excision of granulation tissue was done in 7 patients. Rethi procedures(anterior division of cricoid cartilage, partial wedge resection of lower thyroid cartilage and T-tube molding) were performed in 2 subglottic stenosis patients. And the other subglottic patient was received permanent tracheal fenestration at 1975. The tracheoesophageal fistula patient was done sleeve tracheal resection and end-to-end anastomosis with interrupted double layer closure of esophageal fistula site. Cervical approach was used in 49 cases, cervicomediastinal in 13 cases and median stemotomy In 6 cases. Techniques for obtaining tension-free anastomosis included a cervical neck flexion(15-30$^{\circ}$) in all sleeve resection patients and laryngeal release in one. The length of resection was 1.5 to 5.0 on A total of 41 patients(74.5%) had good(24 patients) or satisfactory(17 patients) results. But in ten cases, the restenosis of anastomosis site which is the most common complication was developed Two of them underwent a second reconstruction and 8 patients required T-tube insertion for airway maintenance. Three patients(5.4%) died. The causes of death were tracheo-innominate artery fistula(2) and sudden obstruction of airway(1).

The present treatment of respiratory failure, using cuffed endotracheal and tracheostomy tube has produced, apparently with increasing frequency, three lesions which have serious ceminical manifestations such as tracheal stenosis, tracheomalasia, and localized tracheal erosion. Extensive resection and reconstruction of the trachea must be necessary because conservative treatment has generally failed in the fully developed stenotic lesion. of the mediastinal trachea following extensive resection is best accomplished by direct anastomosis of the patient`s own tracheobronchial tissue. Any replacement of the mediastinal trachea must be air tight and laterally rigid, and must heal dependably. A variety of materials has been used for substitution following circumferential excision of tracheal segments within the mediastinum. These attempts have often failed because of early leak or late stenosis. We have successfully performed circumferential resection and primary end-to-end anastomosis of the trachea for 4 cases of post-intubation tracheal stenosis located a few centimeter below the tracheostomy stoma in the period of 3 years between 1974 and 1976. The lesion in one patient was found in the upper trachea which was approached anteriorly through a cervicomediastinal incision with division of the upper sternum. Other three located in the lower half of the trachea were operated through a high transthoracic incision with appropriate hilar mobilization in addition to cervical flexion for the development of the cervical trachea into the mediastinum. There were no hospital death, but suture line granulations occurred in two patients were managed by bronchoscopic removal of granulations without difficulties.

From 1988 to 1995, 59 patients with laryngotracheal stenosis were operated with resection of stenotic segment and end to end anastomosis in Seoul national university. Among these patients, 36 were tracheal stenosis, 17 were combined lesion of subglottis and trachea and 5 were subglottic stenosis. The success of procedure was determined by stoma closure or decannulation and an overall 89.8% success rate was achieved following 165 procedures. The success rate showed correlation with severity of stenosis and the number of procedures done was related to the site of stenosis. There was no mortality and granulation formation, unilateral vocal cord palsy were the common complication of end to end procedures.

Tracheostomal stenosis after total laryngectomy is a distressing complication which con-tributes significantly to both psychosocial and physical morbidity according to nature and severity in laryngectomee. Sternal stenosis will compromise not only optimal air exchange, crust formation but also the ability to clear tracheobronchial secretion, so pneumonia and atelectasis will develop. Having a number of procedure recommended for correction of such stenosis with limited results. We developed new technique which is based on tracheal advancement flap had been ap-plied to 12 patients, successfully. We think that total or partial tracheal advancement flap technique Is useful for widening the stoma and advantages of this method are following. 1. Simple technique. possible under local anesthesia 2. Healthy tracheal ring facilities width control 3. Less chance of refractory scar stenosis 4. Tracheoesophageal shunt can be constructed after the partial advancement flap.

A 10-year-old Thoroughbred mare was referred to the Jeju National University Equine Hospital with roaring, dyspnea, and weight loss. On endoscopic examination, the horse was diagnosed with right arytenoid chondritis. Surgical treatment was selected due to the failure of a previous medical treatment. Permanent tracheostomy was performed in a standing position. The horse was restrained and tied in a proper position in the stock. The cranial parts of the 2nd to 5th tracheal cartilages were resected, as were the associated skin, mucosa, muscle, and cartilages. After the stoma was formed, external mucosa and skin were sutured using a simple interrupted method. The horse was hospitalized for 22 days receiving postoperative care including antibiotics, non-steroidal anti-inflammatory drugs, dressing as required, and was pregnant six months after the surgery. A permanent tracheostomy is thought to be effective in horses with diseases causing upper respiratory tract obstruction.

Reconstruction of the pharynx and cervical esophagus presents a tremendous challenges to surgeons. Over the past 2 years[1990, Dec.-1993, Jun], the free jejunal graft has been performed in 17 cases in Korea Cancer Center Hospital.The indications of this procedures were almost malignant neoplasms involving neck and upper aero-digestive tract; Hypopharyngeal cancer[12 cases, including 2 recurrent cases], laryngeal cancer[2 cases], thyroid cancer[2 cases, including 1 recurrent case], cervical esophageal cancer[1 case]. There were fifteen men and two women, and the mean age was 59.6 years. The anastomosis site of jejunal artery were common carotid artery[16 cases] or external carotid artery[1 case] and that of jejunal vein were internal jegular [15 cases] or facial[1 case] and superior thyroid vein[1 case]. The length of jejunal graft was from 9 cm to 17 cm[mean 13 cm] and the mean ischemic time was 68 minutes. There was one hospital mortality which was irrelevant to procedures[variceal bleeding] and one graft failure[1/16]. Other postoperative complications were neck bleeding or hematoma[3 cases], abdominal wound infection or disruption[5 cases], anastomosis site leakage[1 case], pneumonia[2 cases], graft vein thrombosis[1 case], and food aspiration[1 case]. The function of conduit was excellent and ingestion of food was possible in nearly all cases. Postoperative adjuvant radiation therapy was also applicable without problem in 7 cases. During follow-up periods, the anastomosis site stenosis developed in four patients, and the tracheal stoma was narrowed in one case but easily overcome with dilation. In conclusion, we think that the free jejunal graft is one of the excellent reconstruction methods of upper digestive tract, especially after radical resection of malignant neoplasm in neck with a high success rate and low mortality and morbidity rate.
