1/27. Successful resection of endotracheal papillary adenocarcinoma by endoscopic electrosurgery using a new snare: report of a case.

    We report herein the rare case of a patient with endotracheal papillary adenocarcinoma of the goblet cell type. The tumor existed in the upper trachea, obstructing 95% of the airway, and prompt palliation was required. Endotracheal polypectomy was successfully performed in this patient using electrosurgery with a new snare designed for the respiratory tract. The procedure took only a few minutes and the dyspnea was relieved promptly without any complications. The alternative techniques for palliation of bronchial stenosis are also discussed.

2/27. Endoluminal laser application under percutaneous cardiopulmonary support in severe tracheal stenosis.

    Laser ablation under bronchoscopic guidance was conducted on 2 patients with severe tracheal stenosis. Case 1 was a 57-year-old man admitted to our emergency unit because asphyxia. bronchoscopy showed the lumen occluded at the bifurcation by tracheal cancer. Case 2 was a 62-year-old woman who underwent tracheostomy elsewhere for respiratory failure caused by a brain contusion and was treated for 3 months. After transfer to our emergency unit, bronchoscopy showed severe tracheal stenosis. Tracheoplasty conducted under bronchoscopy used a noncontact Nd:YAG laser at an output of 10-40 W and irradiation time of 1 second per shot. Total irradiation energy was 1700-1900 J. Percutaneous cardiopulmonary support was used during the laser procedure due to asphyxia. All procedures were completed satisfactorily and clinical symptoms improved dramatically in both cases. Laser tracheoplasty under bronchoscopic guidance treated severe stenosis safely and completely. Percutaneous cardiopulmonary support was very useful in preventing severe respiratory failure or asphyxia during this procedure.

3/27. Airway stenting for tracheal stenosis.

    patients with upper airway obstruction from malignant disease are difficult to manage. A 62 year old patient presented with stridor and was found to have an upper tracheal tumour. bronchoscopy, dilatation and stenting were performed successfully. The techniques and indications for the use of dynamic airway stent are discussed.

4/27. Treatment of severe carinal stenosis with overlapping metallic endoprosthesis.

    A 50-year-old man presented with respiratory distress from central airway compression secondary to malignant mediastinal adenopathy. The stenosis involved the carinal triangle and created residual luminal diameters of 6 mm, 6 mm, and pinhole in the distal trachea and right and left mainstem bronchi, respectively. Airway patency at the carina was restored successfully with a stenting method that uses two overlapping Wall stents.

5/27. Intramural neurofibroma of the trachea treated by multiple stents.

    The case history is presented of a patient in whom an intramural tracheal neurofibroma developed, causing severe airway stenosis. The patient was treated with multiple stents over a period of 5 years because of progression of the disease and associated airflow limitation. Clinicians should be aware of this rare complication of neurofibromatosis.

6/27. Primary solitary lymphoma of the trachea.

    A case history is reported of an 81-year-old woman with progressively increasing airway obstruction and progressive stenosis of the intrathoracic trachea. Repeated endoscopic biopsies failed to establish a diagnosis. At thoracotomy, an isolated tumor mass was found originating in the trachea without grossly apparent mediastinal nodes. biopsy of the tumor mass revealed lymphoma. Radiotherapy resulted in complete remission, which continues at 22 months.

7/27. Temporary stenting for malignant tracheal stenosis due to esophageal cancer: a case report.

    We present a case of a 56-year-old male with esophageal cancer who underwent successful temporary tracheal stenting followed by a surgical procedure. The trachea was obstructed owing to endotracheal metastasis and the patient had severe dyspnea. A silicone Y-stent was initially inserted into the tracheal stenosis to secure the airway, and then tumor-specific chemo-radiotherapy was applied. The tumor was reduced, the stent was removed and a pathological study indicated that the tracheal metastasis had disappeared. The patient then underwent esophagectomy and tumor-specific chemo-radiotherapy was continued after the surgery. The patient has remained alive and free of esophageal cancer for 18 months after the airway stent emplacement. These findings suggested that the silicone stent was suitable as a temporary measure and that temporary stenting combined with tumor-specific therapy was effective as part of the aggressive therapeutic strategy with which to treat the malignant airway stenosis due to esophageal cancer.

8/27. Successful treatment of tracheal mucoepidermoid carcinoma using rigid bronchoscopy combined with conventional surgical resection.

    Mucoepidermoid carcinoma of the trachea is a rare tumor. This investigation reports on a case of a 67-year-old male with mucoepidermoid carcinoma in the lower 1/3 of the trachea. The patient presented with intermittent coughing and hemoptysis lasting for 1 month. The preoperative investigation revealed an intraluminal polypoid mass in the posterolateral trachea with 75% stenosis of the tracheal lumen. A rigid bronchoscope was used to evaluate the airway before surgery, and the tumor was mechanically resected using the tip of the rigid bronchoscope just before intubation. Finally, the tumor was completely removed, and the airway was successfully reconstructed. At 6 months after surgery with no adjuvant chemoradiotherapy, the patient was free of disease.

9/27. Primary tracheal lymphoma: case report and literature review.

    We describe a 20-year-old Japanese woman with anaplastic large cell lymphoma in whom primary tracheal involvement was associated with life-threatening airway obstruction. After debulking surgery, the patient was successfully treated with chemotherapy and radiotherapy. A total of 28 cases of primary tracheal lymphoma were reviewed. Common clinical features included predominance of localized disease, respiratory symptoms resembling acute asthma, absence of hemoptysis, and rapid progression of tracheal stenosis. Various histological subtypes of primary tracheal lymphoma exist and are likely to determine prognosis.

10/27. Surgical treatment of adenoid cystic carcinoma of the left main bronchus and trachea by left pneumonectomy, resection of 7.5 cm of trachea, and direct reanastomosis of right lung.

    A 23-year-old woman, who had suffered recurrent acute bronchitis, dyspnoea, and stridor, was found to have a tracheal stenosis and complete left main bronchus obstruction. biopsy of the tumour showed an adenoid cystic carcinoma. After pneumonectomy the trachea was closed through tumour tissue. Two weeks later a right thoracotomy showed that a tumour had invaded the trachea from the carina up to 6 cm and the right stem bronchus for 1 cm. Under extracorporeal circulation 7.5 cm of the trachea and right bronchus were resected. A direct tracheal anastomosis was easy to perform. Spontaneous respiration with efficient coughing returned after five days. Unfortunately, one month later, high fever caused by a lung abscess developed, which provoked a massive haemoptysis with fatal outcome.
