ENB-GS-TBLB for the Diagnosis of PPLs

ENB is performed using an electromagnetic navigation system (LK-DW-NK-Z; Suzhou Lungcare Medical Technology Inc., China) with an internal locatable guide (LG; Lungcare) with diameter of 1.45 mm. Bronchoscopes with a working channel diameter of 2.0 mm are used (BF-260 and BF-P260F; Olympus, Japan). The LG is inserted into the GS(K-201; Olympus) beforehand, and the GS-covered LG is introduced via the working channel of the bronchoscope and navigated to the PPL finally. The LG and GS are confirmed to reach the lesion by radiograph fluoroscopy.

A GS is introduced in the working channel of the bronchoscope alone. The GS is confirmed to reach the lesion by radiograph fluoroscopy, pathologic specimens are obtained under fluoroscopic guidance.
