Stenosing airway disease is classified as intraluminal obstruction, extrinsic compression, and malacia by the anatomical site of the lesion. Stenting therapy is indicated for symptomatic relief of life-threatening dyspnea caused by the last two types. Airway stents are made with metal mesh and/or silicone rubber, and currently more than 20 kinds of stent are available. Among many kinds of silicone stent, the Dumon stent is mostly widely used for benign and malignant airway stenoses, but general anesthesia and rigid bronchoscopy are needed for insertion. It can be removed when the stenosing airway disease subsides completely. In many clinical studies, most patients $(85-90\%)$ improved immediately after stenting, and procedure-related mortality was low $(<3\%)$ in experienced centers. Stent displacement, mucus impaction, and granulation tissue formation are potential complications. Stenting is one of many effective therapeutic modalities for stenosing central airway disease. Careful patient selection, experiences, and continuous development of new technology will bring better results.

Papillary thyroid carcinoma is rarely associated with macroscopic vascular invasion or tumor thrombosis. Especially, superior vena cava syndrome(SVCS) resulted from tumor thrombosis of papillary thyroid carcinoma is extremely rare. We present herein a case of SVCS caused by tumor thrombosis from papillary thyroid carcinoma which was successfully solved by intravascular placement of self-expandable stent in 74-year-old woman.

Conservative management of 3 iatrogenic perforations of intrathoracic esophagus was reviewed. The primary disorders were achalasia in 2 patients and congenital tracheoesophageal fistula in 1 patient. Perforation occurred after treatment of the primary disorders in the distal esophagus in 2 patients and mid-thoracic esophagus in 1 patient. All the perforations appeared late after the previous treatments and the inflammation spread to mediastinum and pleural cavity in all the 3 patients. Conservative management of esophageal perforation was carried out with intraluminal drainage from the perforated site of esophagus[insertion of Levin`s tube and continuous suction], pleural drainage and feeding of liquid diet through gastrostomy tube with Fowler`s position. The patients revealed spontaneous closure of perforated sites about 3 to 4 weeks after this conservative management without open thoracotomy. This result suggests that this conservative management may be accepted as therapeutic method in the thoracic esophageal perforations regardless of cause and time of the perforation.

Although it is suspected that the foreign body sensation on the pharyngoesophageal region is caused by motility disturbance of upper esophageal sphincter, its pathophysiology is not yet clear. Esophageal manometry has become an important diagnostic tool in the evaluation of esophageal motor disorders such as dysfunction of upper esophageal sphincter. Intraluminal esophageal pressures were measured by perfusion manometry in fifteen patients with foreign body sensation on the pharyngoesophageal region and in twenty six controls. In upper esophageal sphincter, mean value of resting pressure of the patients by rapid pull-through technique was 45,9\ulcorner 15.6mmHg and 80.9\ulcorner9.7mmHg in the controls. The difference between the two groups was statistically significant. The distance from nostril to sphincter, length of sphincter, and resting pressure by station pull-through technique were not significantly different. The amplitude of esophageal peristalsis in the patients was reduced significantly at the level of the upper, mid and lower esophagus. The wave duration of the patients was reduced significantly at the level the upper and mid esophagus. The speed showed no difference between two groups. Length and resting pressure of lower esophageal sphincter revealed almost same values in two groups.

Esophageal pH monitoring is considered the gold standard for the diagnosis of gastroesophageal reflux disease because of the normal ranges across the pediatric age range. However, this method can only detect acid reflux. Multichannel intraluminal impedance-pH (MII-pH) monitoring has recently been used for the detection of bolus reflux in infants and children. This method allows for the detection of liquid, gas or mixed reflux in addition to acid, weakly acidic or weakly alkaline reflux. MII-pH monitoring can record the direction of flow and the height of reflux, which are useful parameters to identify an association between symptoms and reflux. However, the technique is limited by its high cost and the lack of normative data of MII-pH in the pediatric population. Despite certain limitations, MII-pH monitoring will become more common and gradually replace pH monitoring in the future, because pH monitoring is part of MII-pH.

Leiomyoma of the trachea is a rare benign tumor. A case of leiomyoma of the thoracic trachea is described in a 46-year-old woman. The patient complained of productive cough, dyspnea and blood-tinged sputum since July 1993. Plain chest radiographs were not helpful, but computed tomography of the chest showed an intraluminal tracheal mass just above the carina. Fiberoptic bronchoscopy revealed a broad based, nodular mass rising from the posterior tracheal wall, just above the carina. The tumor was excised by sleeve resection and end-to-end anastomosis of the trachea was performed. The patient`s postoperative course was uneventful. She was discharged on the 20th postoperative day.

Laryngopharyngeal reflux disease (LPRD) is the result of retrograde flow of gastric contents to the laryngopharynx. Laryngoscopic findings and special questionnaires are first step of diagnosis of LPRD. Empiric trials of Proton pump inhibitor' test (PPI test) is recommended as treatment and diagnosis. However confirmation of reflux is then recommended primarily in patients with persistent symptoms despite acid-suppressive therapy. The 24 hour ambulatory double pH monitoring has been a gold standard method in diagnosis of LPRD even though it has some limitation. The combined multichannel intraluminal impedance and pH monitoring is a new-rising test tool. It can detect acid/non-acid, liquid/gaseous reflux and clearance of refluxate. The water siphon test is also used for diagnosis of LPRD.

We experienced one case of endobronchial hamartoma on left lower lobar bronchus in sixty year old male patient. Less than 1 % of lung tumors are benign, and the prevalence of endobronchial hamartoma is reported to be from 3 % to 40 %. The mean age was 52.9 years, and equal gender prevalence.Symptoms were related to intraluminal growth, including fever, chill, productive cough, hemoptysis, exertional dyspnea, recurrent pneumonia and so on. Bronchoscopic finding was tumor present as polypoid mass in the lumen of a left main stem bronchus,distal to 3 cm from carina. Biopsy was done. The histopathologic pattern showed several nodules of loose myxoid tissue and islands of cartilage. We performed partial resection of the affected bronchus,1cm anterior to the superior segmental bronchial opening to just distal from superior segmental orifice. Including superior segmentectomy, partial resection of the left lower lobar bronchial resection and end-to-end anastomosis with 4-0 Poly dioxanone sutere materials interruptedly. We report this case with the brief review of literatures.

In the last few years there has been a resurgenceof interest in in-situ saphenous vein arterial bypass for lower extremity revascularization because of improved patency rates. we performed 1 in situ bypass oreration using the intraluminal valve-disruption tecnique. A 65-year-old female who had ztherosclerotic obstruction in the superficial and popliteal arteries underwent in situ saphenous vein arterial bypass. After harvesting of saphenous vein, we used LeMaitre retrograde valvulotome for valve-disruption technique. Completion of the arterrigraphy was performed to evaluate bothh the anastomoses. The two side brances were all ligated. In situ saphenous vein arterial bypass has become the procedure of choice for distal reconstruction in severely ischemic lower extremities because of improved long-term patency compared with reversed-saphenous vein bypass procedure.

A 16-year-old cat presented with a 2-week history of anorexia and lethargy. Radiography revealed a soft-tissue opacity, heart-shaped mass between the descending colon and urinary bladder. Ultrasonography showed a large uterine body with a heterogeneously hypoechoic, thickened wall and hypoechoic intraluminal fluid. Computed tomography revealed a large, fluid-filled uterine mass with contrast enhancement, without evidence of regional lymph node or pulmonary metastasis. Ovariohysterectomy was performed and leiomyosarcoma was confirmed by histology. No notable abnormalities were observed during the 1-year postoperative follow-up periods. This report describes the diagnostic imaging and treatment of a rare case of feline uterine leiomyosarcoma.
