摘要:

Bronchial needle aspiration (BNA) is a standard technique for collecting cytology specimens through flexible bronchoscopy. BNA is a safe and effective means for diagnosing malignant and nonmalignant diseases, but it is an infrequently used technique. Previous authors have reported that extensive training is necessary to become competent in the procedure, concluding that at least 50 procedures are necessary. This retrospective review suggests that pulmonary fellows can become facile in the technique more quickly with fewer than a dozen trials.

摘要:

The gold standard for removal of foreign bodies from airways is rigid bronchoscopy in the operating room with the patient under general anesthesia. Flexible bronchoscopy is performed frequently in young children with recurrent or persistent pneumonia, and a foreign body may be found in the airway during the procedure. Pediatric flexible bronchoscopes have a narrow inner suction channel that does not allow the use of appropriate forceps to remove the foreign body. We describe five cases of foreign bodies found during routine flexible bronchoscopy (using a pediatric bronchoscope; Pentax FB10X) in children. The foreign bodies were extracted during the same anesthetic period using a laryngeal mask airway introduced through the mouth and a large flexible bronchoscope (Pentax FB15X) through which forceps were passed. This method allows the pediatric bronchoscopist to remove a foreign body during the same procedure and during the same anesthetic period.

摘要:

Eleven women have been admitted to our clinic with turban pin aspiration since October 1996. All patients except two were admitted within the day of aspiration. The other two patients were admitted 5 days after pin aspiration. The aspirated pin was localized in the right lung in seven patients and in the left lung in four patients. The pins were retrieved successfully with a flexible bronchoscope in 8 of 11 patients. In one of these eight patients, the pin was removed using the flexible bronchoscope through a rigid bronchoscope. In one patient, the pin dropped from the forceps in the pharynx, and was later excreted in the feces. Thoracotomy was performed in two patients because both rigid and flexible bronchoscopies were unsuccessful in retrieving the pins. Flexible bronchoscopy alone or in combination with rigid bronchoscopy is a successful method for retrieving aspirated pins.

摘要:

Needle breakage is a potential technical complication of bronchial needle aspiration (BNA), but has not been reported previously. We present a patient in whom, following BNA of neoplastic adenopathy, the aspirating needle separated from its Teflon catheter and remained embedded in the airway wall. The needle was removed uneventfully with forceps, no marked bleeding or airway trauma occurred, and a BNA diagnostic of malignancy was obtained subsequently without problems. The rarity of needle breakage underscores the overall safety of BNA and the importance of careful appraisal of the needle before each pass, strict adherence to guidelines for needle placement and aspiration, and familiarity with principles of foreign body retrieval and supportive care should problems arise.

摘要:

We report a 40-year-old man with a right lung mass. Flexible bronchoscopy revealed a fleshy growth in the right upper lobe bronchus. After an endobronchial biopsy was acquired, active hemorrhage occurred from the lesion. The bleeding did not respond to saline and epinephrine instillation through the bronchoscope. Intralesional injection with diluted epinephrine solution through a transbronchial cytology needle resulted in bleeding cessation. The possible mechanisms of bleeding control include vasoconstrictive and tamponade effects. This procedure may be considered a treatment option for a patient with a bleeding endobronchial mass lesion after biopsy.

摘要:

We describe the use of streptokinase for dissolution of an endobronchial clot in a uremic patient who was admitted initially for acute myocardial infarction and subsequent pulmonary edema. The patient required assisted ventilation and developed spontaneous, massive endobronchial bleeding that led to airway obstruction, resulting in a complete collapse of the left lung. The endobronchial clot could not be aspirated or removed using the usual bronchoscopic techniques. We injected 80,000 U streptokinase through a flexible bronchoscope in an attempt to dissolve the clot. Partial success was achieved, but the remaining clot was removed easily using forceps and suctioning, and the lung was fully reexpanded. Bleeding recurred 4 days later and was treated successfully by bronchial artery embolization.

摘要:

We report here a case of papillary serous carcinoma of the ovary with metastasis to the lung in a 74-year-old woman. Three years after initial diagnosis of ovarian cancer, the patient presented with cough and was found to have a right upper lobe mass. Examination by flexible bronchoscopy showed extensive airway nodules. Biopsy of the airway lesions revealed metastatic papillary serous carcinoma. A review of the literature on the spread of ovarian malignancies to the lung is presented in the discussion.

摘要:

Endobronchial lipomas are rare, benign lesions that usually obstruct a major bronchus and cause irreversible pulmonary damage distally. Endobronchial lipomas originate from fat cells located in the peribronchial tissue and occasionally the submucosal tissue of large bronchi and comprise only approximately 0.1% of all tumors and approximately 13% of benign pulmonary tumors. They may be diagnosed clinically as bronchial adenoma or malignant lesion, and the result of delayed therapy may be bronchiectasis. Treatment includes local resection through a bronchoscope or a bronchotomy incision, or removal, if necessary, of the obstructed lobe or lung at thoracotomy. We report a case of a endobronchial lipoma treated successfully with lobectomy in a 42-year-old man.

摘要:

A case of endobronchial Kaposi's sarcoma is described in a 50-year-old man seropositive for human immunodeficiency virus. He had a history ofPneumocystis cariniipneumonia and cryptococcal meningitis. He presented without any pulmonary symptoms. Computed tomography of the chest showed bilateral nodules. Bronchoscopy demonstrated well-demarcated dark-brown discrete lesions that were not raised. Video-assisted thoracoscopic biopsy of the lung nodule demonstrated pathologic findings consistent with Kaposi's sarcoma. The patient was treated with highly active antiretroviral therapy and had regression of the disease. This case emphasizes the importance of bronchoscopy in the diagnosis and the effectiveness of highly active antiretroviral therapy in the treatment of pulmonary Kaposi's sarcoma.
