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

Esophageal atresia without tracheoesophageal fistula accounts for 7-11 % of all types of esophageal atresia and is very difficult to treat. In our hospital from 1990 to 2005, we operated upon 40 patients with esophageal atresia, and 6 had pure atresia. The preoperative characteristics, operative findings and post operative course of the six patients with pure atresia were analysed. Immediate gastrostomy was performed in all 6 patients. One patient had simultaneous cervical esophagostomy. Esophageal reconstruction procedures were transhiatal gastric pull up in 3 patients, esophagocologastrostomy utilizing left colon in 1, and transthoracic esophagoseophagostomy with esophageal bougination in 2. Postoperative complications were pneumonia, anastomosis leakage, and gastroesophageal reflux symptom. Conservative management was effective in all patients. A larger series of cases would be required to demonstrate the most effective treatment for this particular anomalous condition.

"Middle lobe syndrome" which was described y Graham and associates at first is always caused by ex- ternal bronchial compression by Iymph nodes. Although the patients may not present any symptom, the most common presenting symptoms were cough, dyspnea, fever, hemoptysis, and chest pain. Diagnostic procedures includ chest X-ray bronchoscopy, brochography, chest CT, and the principal finding is the contracted middle lobe which is usually airless. We experienced fifteen cases of middle lobe syndrome from April 1990 to May 1995. Eleven patients were treated surgically. The surgical candidates for middle lobe syndrome are suspicious malignancy, fixed bronchiectasis, bronchostenosis, intractable to medical treatment, recurrent infection. Operations were right middle lobectomy (8), right middle and lower bilobectomy (2), right upper and middle bilobectomy (1). Postoperative histological findings were tuberculosis in six, chronic inflammation in three, malignancy in one, and focal hemorrhage in one. There were two cases of postoperat ve complications which were postoperative atelectasis and hepatopathy.patopathy.

To study the clinical profiles and outcome of surgery in infants with esophageal atresia, we reviewed 96 esophageal atresia cases who were treated from April, 1978 to June, 1995. There were 51 male and 45 female infants, a ratio of 1.1:1. The low birth weight(<2500g) patients were 32%. Clinical findings at the time of diagnosis included drooling in 57%, choking in 50%, cyanosis in 38%, respiratory distress in 27% and swallowing difficulty in 20%. Gross classification included 6 cases of type A esophageal atresia(6%), 79 cases of type C(82%), 3 cases of type E (3%) and 8 cases of type F(8%). Associated anomalies occurred in 34 infants(35%). Among them, cardiac anomalies were most common(60%). A primary repair of the defect was carried out in 76 patients with type A or C. A staged operation comprising a repair or gastric tube interposition after gastrostomy was performed in 8 patients. In all 3 infants with H-type, a division of fistula was performed. Esophageal resection and anastomosis was done in 8 infants with esophageal stenosis. In one infant, a gastrostomy was performed and he expired before staged operation. Anastomotic complications included leakage in 16 cases(17%), stricture in 37 cases(39%) and recurrent tracheoesopohageal fistula in 3 cases(3%). The mortality rate was 14% and the leading cause of death was pneumonia. The overall survival rate was 86%, and according to Waterston criteria, the survival rates were 93%, 85% and 58% in class A, Band C, respectively. 75 patients were followed up with median follow up 6.4 years. Among them, 93% were uneventful and 7% had frequent pneumonia.

A clinical study was performed on 152 cases of surgical esophageal disease treated by the Department of Thoracic & Cardiovascular Surgery of Korea University Hospital from Jan. 1989 through July 1994. The most common esophageal disease was cancer which was seen in 73 cases (48%) among 152 cases. All were treated surgically' 52 patients (71%) were managed by curative or palliative resection with reconstruction and feeding gastrostomy or jejunostomy, otherwise Celestine tube insertion was performed on the remaining 21 patients for palliatio'n. Esophageal leiomyoma occurred in 6 cases(3.9%), among them 1 case was performed with trio recoscopic enucleation . Achalasia were in 7 cases (4.6%) and was treated with modified Heller's m otomy and with Belsey Mark IV operation. Diverticulum were in 11 cases (7.2%). Esophageal stricture occurred in 20 cases (14.1 %) and 17 of 20 cases were managed with bypass surgery. Esophageal perforation was seen in 20 cases, its cause was instrumental trauma in 7 cases, stab wound in 4 cases, foreign body in 4 cases, spontaneous perforation in 3 cases, and others 1 case Other disease including congenital lesion was seen In 1 Scases.

Background and Objectives : The treatment of supraglottic stenosis remains a challenging problem in the field of otolaryngology due to its association with dyspnea, dysphagia, and frequent recurrence. Any satisfactory treatment is not yet known. The author experienced six cases of supraglottic stenosis and report the successful treatment of five cases by repeated endoscopic laryngeal excision with KTP-532 laser under suspension layngoscopy. Materials and Methods : Six adults who were treated for supraglottic stenosis between March 1994 and December 1998 at the Department of Otoloaryngology-Head and Neck Surgery, Korea University Medical Center were studied retrospectively. The patients were placed under general anesthesia followed by endoscopic laryngeal excision with KTP-532 laser under supension laryngoscopy. The scar tissue and granulation tissue were visualized with an operating microscope, and then removed using KTP-532 laser (15watts, continuous mode). Intraoperative local steroid(Triamcinolone ) was injected in all cases after the stenotic portions were removed. Results : Endoscopic excision was performed in five cases ; among the five cases, cricoid cartilage was concomitantly removed in two cases, and epiglottis was removed in one case. Satisfactory swallowing and airway respiration were possible in all five patients who underwent endoscopic widening. Conclusion : The treatment of supraglottic stenosis is different from that of tracheal or glottic stenosis in that supraglottic stenosis is mainly developed in membraneous form. Repeated laser excision and local steroid injection under suspension laryngoscopy is an effective and recommend able method for the treatment of supraglottic stenosis.

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: Surgical treatment of corrosive esophageal stricture with colon interposition was very widely used. The colon interposition advantage is low reflux esophagitis risk and preservation of gastric capacity and peristalsis. This procedure was introduced by Orsoni and much improved. But, if stomach injury was minimal, gastric interposition is useful due to simple technique and low complication. Material and Method: Esophageal reconstruction by the transhiatal esophagectomy and intracervical esophagogastrostomy was done in 7 patients of corrosive esophageal stricture at Dong-San medical center from January 1998 to December 2007. Result: There were six female and one male patients raBackground Surgical treatment of corrosive esophageal stricture with colon interposition was very widely used.

Background : Ever since Flexible Fiberoptic Bronchoscopy was introduced into clinical practice, it has played an important role in both diagnosis and therapy of respiratory diseases. Repeated bronchoscopic examinations is are not so uncommon. This study was designed prospectively to assess the clinical availability of the Repeated Flexible Bronchoscopy (RFB). Methods : Pre-established indications were as follows : 1) To confirm diagnosis or the cell type in proven malignancy 2) to diagnose or locate hemoptysis 3) to follow-up or confirm recurrence 4) to use in therapy. We performed RFB and analyzed the data in 156 patients during 28-month period. Results : The frequency of RFB was 23.0%. The indication for diagnosis or cell type of malignancy was 25 cases, of which 2 cases were confirmed by a third bronchoscopic examination and 3 cases by surgical procedures. Localization of the bleeding site was confirmed in 53.8%. RFB for small cell lung cancer yielded more information on residual or recurred lesion not apparent even with the CT scan in 30%. Previous cases of bronchostenosis due to endo-bronchial tuberculosis was shown to have worsened in 66.7%. Therapeutic manipulations were done in 126 cases, and bronchial suction was most common. Complications showed decreasing tendency with repeated examinations. Conclusion : The RFB for diagnosis or cell type of malignancy was useful in that comfirmation of diagnosis was possible in 85.7% of malignancy. More aggressive procedures should be employed including TBLB or TBNA. The RFB showed possible usefulness in the follow-up of patients with small cell lung cancer. For the patients with hemoptysis or endobronchial tuberculosis, the RFB did not the significance did not show significance because its results did not influence the diagnosis, therapy or clinical course.
