Sentinel lymph node (SLN) biopsy using the near-infrared fluorescence (NIRF) tracer indocyanine green (ICG) may help mitigate these risks by enabling organ-preserving surgery without the need for an anastomosis. It is hypothesized that contrast-enhancing software for NIRF could further improve SLN detection.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>This retrospective study evaluated whether a contrast-enhanced NIRF view improved SLN detection compared to the standard NIRF view of the robotic surgical system (da\u00a0Vinci\u00a0Xi). The contrast-enhanced view was generated using surgical image analysis software (PerfusionWorks), which enhances NIRF visual contrast. A retrospective analysis was conducted using intraoperative videos from SLN mapping with ICG in 10 patients with CC. Fifteen clinicians with varying levels of experience annotated video clips using both the standard and the contrast-enhanced views (44 clips per clinician in total). The sensitivity, specificity, accuracy, time-to-detection, and confidence scores were compared between the two views.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      The contrast-enhanced view significantly improved sensitivity (49.3% to 62.4%,\n                      <jats:italic>p<\/jats:italic>\n                      \u2009&lt;\u20090.001) and accuracy (46.1% to 51.8%,\n                      <jats:italic>p<\/jats:italic>\n                      \u00a0&lt;\u20090.001) compared to the standard view, with a decrease in specificity that was not statistically significant (39.4% to 30.4%,\n                      <jats:italic>p<\/jats:italic>\n                      \u00a0=\u20090.08).
