ENB-GS-TBLB-X-ray Group
The guide sheath(GS) is introduced into the lesion via Electromagnetic Navigation System. ENB: 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. GS-TBLB-X-ray: 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.
GS-TBLB-X-ray Group
The GS is introduced into the lesion via the working channel of a bronchoscope with radiographic fluoroscopy. Once the location of the lesion is identified by fluoroscopy, pathologic specimens are obtained under fluoroscopic guidance. GS-TBLB-X-ray: 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.
