Identification of intersegmental planes is essential for successful anatomic pulmonary segmentectomy. We have previously reported a new fluorescence technique using a PDD endoscope system™ and vitamin B2 for identification of intersegmental planes in ex vivo experiments. In the present study, we investigated and evolved this technique to perform ideal anatomic segmentectomy in a clinical setting using living pig models. ⋯ Our new fluorescence technique in a clinical setting involving a PDD endoscope system™ vitamin B2 enabled accurate and safe anatomic pulmonary segmentectomy, with enough strong and long fluorescence in living pig lungs.
