Scope : BF-P290
Location : Scarred stenosis of trachea and right main bronchus
Patient Information : Female, 56 years old
Medical History : The patient had a history of bronchial tuberculosis and had undergone temporary bronchial metal stent implantation. After the stent was removed, scarred stenosis of the trachea and right main bronchus was left behind.
1. Tracheal scarred stenosis
(TXI™ Technology mode)
In TXI™ technology mode, the scarred stenotic ring and the surrounding pale scar tissue were clearly shown2. Scar tissue hyperplasia of the right main bronchus
(TXI™ Technology mode)
In TXI™ technology mode, the mucosal scar hyperplasia at the mucosal opening of the right main bronchus was shown, which appeared white or grayish-white, and small blood vessels were seen. The boundary between scar tissue and normal mucosa was clear.3. Endoscopic electro-resection of bronchial stenotic scar tissue
(RDI™ Technology mode)
Electrosurgical excision of bronchial stenotic scar tissue was performed in RDI™ technology mode, which clearly showed that the scar tissue was white and whether bleeding occurred.4. Endoscopic electro-resection of bronchial stenotic scar tissue in WLI mode
(WLI)
Bronchial scar tissue hyperplasia was difficult to distinguish from normal mucosa in WLI mode, which was not as clear as in TXI™ technology mode, in which scar tissue could be clearly identified from surrounding normal tissue. When no bleeding occurred, WLI mode was almost as good as RDI™ technology mode. Once bleeding occurred, the RDI™ technology mode gave the operator a clearer field of vision and made it easier to determine how to perform endoscopic resection surgery.Endoscopic electro-resection of bronchial stenotic scar tissue was performed in RDI™ technology mode, which clearly showed that the scar tissue was white and whether bleeding occurred.
Overall comment
In TXI™ technology mode, the bronchial scarred stenotic ring and the surrounding pale scar tissue were clearly shown endoscopic electro-resection of bronchial stenotic scar tissue was performed in RDI™ technology mode, which clearly showed that the scar tissue was white and whether bleeding occurred. The RDI™ technology mode gave the operator a clearer field of vision and made it easier to determine how to perform endoscopic resection surgery.
