Summary

Intersegmental plane identification is a critical step in thoracoscopic anatomical segmentectomy because it helps ensure adequate surgical margins while preserving healthy lung tissue. Indocyanine green (ICG) fluorescence imaging and carbon dioxide (CO₂) inflation-deflation are two techniques used to identify the intersegmental plane, but their agreement and clinical applicability have not been adequately evaluated.

This prospective paired study aims to compare the intersegmental planes identified by ICG fluorescence imaging and the CO₂ inflation-deflation method during thoracoscopic anatomical segmentectomy. In each participant, both techniques will be performed during the same operation, and the identified intersegmental planes will be compared. The findings of this study may provide evidence regarding the agreement and clinical applicability of the two methods for intersegmental plane identification.

Conditions

  • Pulmonary Nodule, Solitary

Interventions

PROCEDURE

Indocyanine Green Fluorescence Imaging

Intravenous indocyanine green (ICG) fluorescence imaging is used intraoperatively to identify the intersegmental plane during thoracoscopic anatomical segmentectomy.

PROCEDURE

Carbon Dioxide Inflation-Deflation

Carbon dioxide (CO₂) inflation-deflation is used intraoperatively to identify the intersegmental plane during thoracoscopic anatomical segmentectomy.
