Application of ICG in Lymph Node Dissection During Radical Resection of Rectal Cancer With Preserved Autonomic Nerves Around LCA and IMA

Indocyanine green NIR imaging is valuable for lymph node dissection in D3 radical surgery for rectal cancer. It can guide the intraoperative improvement of lymph node dissection based on the preservation of LCA and peripheral autonomic nerves of IMA. This not only reduces the occurrence of postoperative complications and promotes rapid postoperative recovery, but also provides a more precise and individualized comprehensive treatment plan for patients after surgery. In addition，this trial also demonstrated that ICG is safe and feasible for use in rectal cancer
