| Outline of Final Research Achievements |
Small lung nodules in peripheral lung are difficult to identify during surgery. Therefore, we developed a new safe and reliable intraoperative marking method using a low power laser light. It irradiated close to the lesion from a bronchus, the site of the lesion can be identified from the lung surface.
We conducted an animal experiment and were able to observe the laser light irradiated in bronchus from the lung surface until the depth of 2cm from pleura. We also could observe the laser light until the depth of 1cm from pleura in human resected lung. Any damages were not detected in the lung around the laser irradiated area in pathological findings.
It might be possible to confirm the localization of small nodules in peripheral lung safely using low power laser light during surgery.
