Tracheo-innominate artery fistula is a rare, but it is one of the gravest complications next to tracheostromy. Early recognition and prompt surgical management is mandatory. The patient was a 66 year old women with MCA infarct who maintained tracheostomy for lyear. She had respiratory arrest due to the excessive bleeding through the tracheostomy site. We report an successful experience for control of bleeding by an innominate artery fistula division and primay suture closure under direct digital compression.

We report a case of subglottic stenosis by blunt neck trauma. Preoperative CT showed a stenosis extending distally from just below the vocal cords for 4cm. Concomittent bilateral vocal cords paralysis and quadriplegia were present. At operation the lesion was severely adhesed and the lumen was nearly obstructed. The recurrent laryngeal nerves were embedded in fibrous tissue and were not identified at ease. The stenosed segment was resected and direct end-to-end anastomosis with preservation of the recurrent laryngeal nerves was performed. Six months latar he discharged with intermediate position of vocal cord paralysis.

Congenital bronchoesophageal fistula is a rare anomaly that can appear in adult life uncommonly. There was a largest review that include 100 cases in the literature. In our case, he was 48 years old male patient who admitted for chronic coughing and recurrent lobar pneumonia on the right lower lobe since 10 years old. We could confirmed the fistular preoperatively by barium swallow examination and performed division of the fistula. The patient’s postoperative course was unremarkable. According Braimbridge’s classification, it was belonged to the type II.

Congenital bronchoesophageal fistula is a rare anomaly that can appear in adult uncommonly. Especially sick sinus syndrome with bronchoesophageal fistula is very uncommon.The patient was 53 years old male who admitted for chronic coughing recurrent lobar pneumonia on RLL since few years ago. And he had familial history of sick sinus syndrome.We confirmed the fistula by barium swallow examination and performed ligation of the fistula and pacemaker implantation.

Congenital esophageal stenosis due to tracheobronchial remnants is one of main forms of congenital esophageal stenosis.A 19-month-old male was presented an appearence of underdevelopment and mild dehydration state due to persistent vomiting since 5 months after his birth. Esophagogram revealed an abrupt narrowing of lower esophagus with dilatation above it. The operation method was aesection of esohageal stenosis and end to end anastomosis through left seventh thoracotomy. The postoperative course was uneventful.

Early recognition, vigorous preoperative preparation, sophisticated supportive care, control of sepsis, and intensive care nursing have produced remarkably improved results in the management of esophageal atresia. Successful surgery for esophageal atresia and tracheoesophageal fistula was carried out recently. Two neonates with esophageal atresia and distal tracheoesophageal fistula were type C. Transpleural end-to-end repair was carried out after gastrostomy due to low birth weight in case I associated with ventricular septal defect. Case 2 underwent primary retropleural end-to-end repair. A simple one-layer anastomosis with the sutures passing through all layers of`the esophagus was performed in all cases.

Myoepithelioma of the trachea is an extremely rare disease. The neoplasm shows histologic features identical to those described in myoepithelioma of salivary glands. The myoepithelioma cells demonstrate the numerous myofilament, desmosomal cellular attachment, cytoplasmic glycogen and pinocytotic vesicles. In immunohistochemical study, myoepithelioma cells show the positive antibody reactions to actin, keratin, vimentin and S-100 protein. A case of myoepithelioma arising from trachea in the seventy-two-year old male diagnosed by microscopic finding and immunohistochemistry is presented.

Congenital bronchoesophageal fistula without esophageal atresia is very rare and often has an insidious clinical course that occasionally persists into adult life. Here are presented five cases of congenital bronchoesophageal fistula without esophageal atresia in adults treated successfully in the Seoul National University Hospital. The patients included two women and three men in the range of 16 and 45 years old. [mean age: 32 years old] Three of five cases could be diagnosed preoperatively by esophagogram and bronchogram but two of them could only be found in operative field. Cineesophagogram is recommended, on review of the literature, to be the most rewarding diagnostic procedure.

Subglottic stenosis is a disorder characterized by narrowing of the airway below the glottis. In children, the stenosis is usually due to scar formation secondary to prolonged airway intubation, rather than to external trauma. The location and extent of the stenosis are highly variable, consequently, corrective measures need to be selected to suit the individual problem. Conservative treatment is adequate for lesser degrees of stenosis but those with more severe scarring require external laryngeal surgery. We managed 2 children with subglottic stenosis due to prolonged intubation after open heart surgery who needed a resectional surgery of the stenotic upper airway. The preoperative evaluation and surgical technique for subglottic stenosis were reviewed.
