Application of flexible fiberoptic bronchoscope used in central lung cancer diagnosis / 中国医学装备

Objective:To investigate the diagnostic value of fiber bronchoscopy for central lung cancer.Methods: The clinical data of 137 patients with central lung cancer were retrospectively analyzed. The diagnostic coincidence rate and the performance of the bronchoscopy were analyzed and compared with the traditional CT imaging examination.Results: The coincidence rate of diagnosis(90.51%) was higher than that of CT (75.91%) (x2=10.450,P<0.05). The diagnostic coincidence rate of flexible fiberoptic bronchoscope of squamous cell carcinoma, undifferentiated carcinoma and adenocarcinoma was 92.86%%, 92.68% and 66.67% respectively. The most common type of the fibrous branch was hyperplasia (61.31%) by flexible fiberoptic bronchoscope.Conclusion:In the diagnosis of central lung cancer, the fiber bronchoscopy has important value of MRI and CT can not be replaced.

The two stage flexible fiberoptic bronchoscoptic awake intubation in a patient with the symptomatic vallecular cyst: A case report

Large symptomatic vallecular cyst is rare, but may cause difficulty or inability in conventional tracheal intubation during induction of general anesthesia. A flexible fiberoptic bronchoscope is the most useful general purpose aid to awake intubation in the patient with a known difficult airway. We experienced a case of flexible video image fiberoptic bronchoscopic awake orotracheal intubation in a patient with the large symptomatic vallecular cyst. A 35-year-old male suffered from foreign body sensation, voice change and dyspnea one month after upper respiratory tract infection. The two step flexible fiberoptic bronchoscopic approach was performed in the management of a known difficult intubation due to a vallecular cyst. We had an uneventful general anesthesia for removal of large symptomatic vallecular cyst because we anticipated difficult intubation.

Fibrobroncoscopía y traqueotomía / Fiberoptic bronchoscopy and tracheotomy

La traqueotomía mantiene la permeabilidad de la vía aérea. La revisión directa de la tráquea a través de la cánula o el traqueostoma por fibrobroncoscopía (FOB), permite ver la mucosa en su porción distal y por arriba del traqueostoma; por esta vía se pueden realizar diversos procedimientos. Objetivo: Evaluar las condiciones de la mucosa traqueal por FOB en casos con cánula de traqueotomía y la utilidad de esta vía de acceso. Material y métodos: Se practicó FOB en 38 pacientes con traqueotomía. Resultados: Las indicaciones más frecuentes de la FOB fueron la aspiración de secreciones, el lavado bronquial con aspiración y la obtención de muestras para estudio bacteriológico. En todos se valoraron las condiciones de la mucosa traqueal, incluidos ocho enfermos con estenosis de la vía aérea en los que se evaluó la mucosa antes y después de procedimientos quirúrgicos. Se encontraron lesiones de la mucosa, anomalías de la pared traqueal, lesiones de las cuerdas vocales y subglóticas. Conclusión: La FOB a través de la cánula o el traqueostoma permite la práctica de diversos procedimientos. La exploración endoscópica por abajo y por encima de la cánula de traqueostomía detecta alteraciones de la mucosa traqueal; en los casos de estenosis de la vía aérea superior, la visión retrógrada con FOB antes y después de las intervenciones quirúrgicas es un paso importante.

Tracheostomy preserves the patency of the airway. Direct exploration through the tracheal cannula or the tracheostoma by fiberoptic bronchoscopy (FOB) allows a view of the conditions of the tracheal mucosa above and below the tracheostoma. Different procedures may be performed thru this approach. Objective: To evaluate the anatomic conditions of the tracheal mucosa by FOB in cases with tracheotomy cannula, and the usefulness of this approach. Material and methods: FOB was performed in 38 patients with tracheotomy. Results: Aspiration of secretions, bronchial lavage with aspiration and bacteriological sampling were the most frequent indications. The conditions of the mucosa were evaluated in all, including eight cases with airway stenosis, both before and after surgical reconstruction. Mucosal inflammation, tracheal anomalies, vocal cords and subglottic lesions were found. Conclusions: FOB trough the cannula or the tracheostoma allows for preoperatory evaluation of the tracheal mucosa. Careful endoscopic exploration above and below the tracheotomy cannula and the tracheostoma may show alterations of the mucosa in cases of airway stenosis both before and after surgical procedures.

One-lung Ventilation using Wire-guided Endobronchial Blocker and Single Lumen Endotracheal Tube: A Case Report / 대한구급학회지

We had done one-lung ventilation using 9 Fr wire-guided endobronchial blocker and outer diameter 41-mm flexible fiberoptic bronchoscope in ruptured esophageal patient who expected difficult tracheal intubation and in esophageal cancer patient who was in need of mechanical ventilation during and after the operation.

Short-term Efficacy of Interstitial Implantation of ~(125)I Seeds Combined with Chemotherapy for Advanced Lung Cancer / 中国微创外科杂志

Objective To evaluate the short-term efficacy of interstitial implantation of 125I seeds by using flexible fiberoptic bronchoscope (FFB) guided by CT for advanced non-small cell lung cancer (NSCLC). Methods A total of 185 patients with NSCLC, who were diagnosed clinically and pathologically, were enrolled into this study and divided into two groups. In 125I seeds group (n=121), the patients received interstitial implantation of 125I combined with NP regimen (NVB+DDP) chemotherapy with a prescribed dose (PD) of 80 Gy. Among the patients, the implantation was guided by CT in 89, and was performed directly under a FFB in 32. In control group (n=64), NP regimen (NVB+DDP) chemotherapy was used. Six months after the treatments, the tumor volume in the two groups was measured by using CT and FFB. The outcomes of the 2 groups were compared, and the efficacy of the treatments was evaluated according to the international standards. Results In the 125I seeds group, the mean radiation dose was 153.7 Gy, matched peripheral dose (MPD) was 89.6 Gy, and D90 was 93.5 Gy. Six months after the treatment, the effectiveness rate (CR+PR) was 95.0% (115/121), and 1-year survival rate was 0.90. In the control group, the effectiveness rate was 42.2% (27/64), and 1-year survival rate was 0.65. There existed significant difference between the two groups (log-rank test, ?2=5.12, Prob=0.04

A case report of fiberoptic intubation in neonate with cleft palate lateral synechia syndrome / 대한마취과학회지

An one day old female baby was admitted to the Pediatric department of Korea University Anam Hospital for the evaluation of her facial anomaly. She was born by spontaneous vaginal delivery at term weighing 3.8 kg. On initial examination, she was noted to have congenital trismus and have cleft lip and palate. Bands of fibrous tissue were noted to extend from the superior alveolar part to inferior part at decidual molar tooth region and allowed oral opening of only 5 mm. She was transfered to the Plastic Surgery department under the diagnosis of cleft palate lateral synechia syndrome for resection of her synechial bands. In the operating room ECG, pulse oximeter and precordial stethoscope were applied to the patient and then, anesthesia was induced with , O2, N2O and enflurane. The 60 cm Olympus fiberscope with an external diameter of 2 mm was used and well lubricated 3.0 mm uncuffed endotracheal tube was threaded over the fiberscope through the oral cavity. The fiberscope was advanced into the midtrachea, then the endotracheal tube was passed over the fiberscope into the trachea After securing of the endotracheal tube, two lateral synechial bands were surgically divided. She tolerated oral feedings on postoperative 5 days without difficulty and discharged from the hospital on postoperative 6 days.
