Abstract:
An 82-year-old male presented with persistent cough and recurrent pneumonia. Computed tomography revealed a high-density foreign body in the right lower lobe posterior basal segment (S10), later identified as a dental prosthesis. Bronchoscopic removal failed due to severe granulation and impaction. Because of low pulmonary function (FEV1: 920 ml), a lung-preserving procedure was selected. We performed thoracoscopic segmentectomy of S10, guided by bronchoscopic injection of indocyanine green (ICG) into B10a and B10b+c. Intraoperative near-infrared imaging clearly delineated the intersegmental plane. The foreign body was successfully removed, and the patient was discharged on postoperative day 7 without complications. This is the first reported case of bronchial ICG-guided anatomical segmentectomy for foreign body removal in an elderly patient. The technique allowed accurate resection with maximal preservation of lung function, demonstrating its clinical utility beyond oncologic indications.

Bronchoscopy
Description
Bronchoscopy is a procedure that involves direct visualization of the larynx, trachea, and bronchi for diagnostic and therapeutic purposes. A flexible fiber optic or rigid bronchoscope is used to carry out the procedure. The fiber-optic bronchoscope is more frequently used due...
