Indocyanine Green Outshines Endoscopic Ultrasound in Colorectal Cancer Node Detection

Indocyanine green (ICG) fluorescence imaging significantly surpasses endoscopic ultrasound (EUS) in diagnosing sentinel and lymph node metastasis in colorectal cancer patients. With sensitivities of 94.44% for sentinel nodes and 80.00% for lymph nodes, ICG proved far more accurate than EUS, which lagged at 40.74% and 28.57%, respectively. The area under the curve for ICG was 0.932 for lymph nodes, underscoring its superior diagnostic value, crucial for improving patient outcomes during surgical interventions.
