Figure 4. Thoracoscopic surgical strategy for a small-sized lung tumor in our institute. WNL: Within normal limit; GGO: ground-glass
opacity; Wedge: wedge resection; Lob: lobectomy; Seg: segmentectomy; ND: nodal dissection.
Figure 5. Current tumor marking method: A hook wire placement is performed under general anesthesia in a hybrid operating room.
After the patient was intubated with a double-lumen tube under general anesthesia, the targeted tumor was identified using C-arm CT
(A). A hook wire was then inserted near the targeted tumor, referring to the CT image (B). After tumor marking, the targeted tumor was
resected via wedge resection.
Figure 6. Precision excision method for small-sized tumors. First, some markings were performed around the targeted tumor using
electrocautery (A). Second, the visceral parenchyma was divided with a sufficient surgical margin using electrocautery (B). Finally, the
parenchyma was divided using an energy device, and the targeted tumor was resected (C).
