| Objectives | |
| Narrative objectives1 | To overcome the limitation of conventional CT-guided marking including complications (air emborisms, bleeding, pneumothorax) adn technical limitations (mainly due to anatomical localization of the target), by using 3D virtual bronchoscopic navigation, bronchoscopic marking is conducted and the efficacy and safety will be examined. |

| Number of participants that the trial has enrolled | 582 | ||||||
| Results | The technique of preoperative bronchoscopic lung marking navigated by virtual bronchoscopy (currently called Virtual-Assisted Lung Mapping (VAL-MAP)) has shown broader application (lung wedge resection, segmentectomy), contributing to precise determination of resection lines with less complications (4 cases of minor pneumothoraces without any need of treatment among 100 cases) compared with conventional methods. |

||||||
| Baseline Characteristics | Selection criteria included patients with pulmonary lesions anticipated to be difficult to identify at thoracoscopy and/or those undergoing sub-lobar lung resections requiring careful determination of resection margins. |
||||||
| Participant flow | Data were collected prospectively and, if needed, compared between the centre that originally developed VAL-MAP and 16 other centres. |
||||||
| Adverse events | Complications associated with VAL-MAP necessitating additional management occurred in four patients (0.8%) including pneumonia, fever and temporary exacerbation of pre-existing cerebral ischaemia. Minor complications included pneumothorax (3.6%), pneumomediastinum (1.2%) and alveolar haemorrhage (1.2%), with similar incidences between the orinitial centre and other centres. |
||||||
| Outcome measures | Five hundred patients underwent VAL-MAP with 1781 markings (3.6+/-1.2 marks/patient). Marks were identifiable during operation in approximately 90%, whereas the successful resection rate was approximately 99% in both groups, partly due to the mutually complementary marks. The contribution of VAL-MAP to surgical success was highly rated by surgeons resecting pure ground glass nodules (P<0.0001), tumours=<?5?mm (P=0.0016), and performing complex segmentectomy and wedge resection (P=0.0072). |
