Indocyanine green (ICG) fluorescence-guided gastric perfusion is an advanced imaging technique used during gastric cancer surgery to assess real-time blood flow and tissue perfusion. By using near-infrared fluorescence, surgeons can better visualize vascularization, improve precision during tumor resection, and support safer anastomoses. This technology enhances intraoperative decision-making and may help reduce postoperative complications in patients with advanced gastric cancer.
