Purpose: Bronchoscopic ethanol injection (BEI) therapy for endobronchial
malignant tumor is thought to be effective modality on airway dilatation
and hemostasis without expensive special equipments. But, if ethanol leaks
in the airway, it cause sever cough and erosion of bronchial wall. Using
endoscopic video information system (EVIS), assistant operator can observe
the leak of ethanol and inject adequate volume. To evaluate the efficacy
and adverse effect of BEI therapy , We treated 8 patients with endobronchial
malignant tumor using EVIS.
Method: Under local anesthesia, video-bronchoscope (Olympus BF200 or BF
1T200) was inserted orally, a transbronchial aspiration cytology (TBAC)
needle is inserted via the biopsy channel, and injections of 0.2ml of 99%
ethanol into the tumor were repeated. After the tumor degenerated to necrotic
tissue, it was removed with a biopsy forceps, and this maneuver was repeated
for the existing fresh lesion.
Results: Total volume of injected ethanol was 4.5+1.6 ml (mean+SD).Airway
obstruction and atelectasis were relieved in 4 cases, and hemostasis were
obtained in 2 cases. In 2 cases, airway dilatation nor hemostasis were not
obtained. BEI was more effective in the patients with polypoid or nodular
tumor protruding into airway lumen. As concerning adverse effects, ethanol
leak caused severe cough in 2 cases, although those were tolerable to continue
the treatment.
Conclusions: BEI therapy using EVIS was thought to be useful to control
airway obstruction by endobronchial polypoid tumor with good cost-effectiveness
and less adverse effects.
