Procedure Information

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 mode)

In TXI mode, the scarred stenotic ring and the surrounding pale scar tissue were clearly shown

2. Scar tissue hyperplasia of the right main bronchus (TXI mode)

In TXI 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 electroresection of bronchial stenotic scar tissue (RDI mode)

Electrosurgical excision of bronchial stenotic scar tissue was performed in RDI mode, which clearly showed that the scar tissue was white and whether bleeding occurred.

4. Endoscopic electroresection 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 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 mode. Once bleeding occurred, the RDI mode gave the operator a clearer field of vision and made it easier to determine how to perform endoscopic resection surgery.

Endoscopic electroresection of bronchial stenotic scar tissue was performed in RDI mode, which clearly showed that the scar tissue was white and whether bleeding occurred.

Overall comment

In TXI mode, the bronchial scarred stenotic ring and the surrounding pale scar tissue were clearly shown. Endoscopic electroresection of bronchial stenotic scar tissue was performed in RDI mode, which clearly showed that the scar tissue was white and whether bleeding occurred. The RDI mode gave the operator a clearer field of vision and made it easier to determine how to perform endoscopic resection surgery.
