Indocyanine Green Clinical Trial
Official title:
Applications of Near-infrared Fluorescence Imaging Guided Lymph Node Dissection and Fluorescence Angiography of Inferior Mesenteric Artery Assisted Left Colic Artery Preservation: A Prospective Randomized Controlled Study
To investigate the accuracy of fluorescence angiography technique IMA classification and the impact of lymph node mapping technique on the dissection of No. 253 lymph nodes.
Multiple studies, including randomized controlled trials (RCTs), have demonstrated that lymph node imaging techniques can effectively increase the number of harvested lymph nodes in gastric and colorectal cancer surgeries . However, there remains a scarcity of research specifically focused on the surgical procedure of fluorescent-guided clearance of No. 253 lymph nodes. Most existing studies have been retrospective analyses, and the need for prospective studies is evident. Further clinical research is crucial to explore the successful application of fluorescence lymph node imaging combined with indocyanine green (ICG) fluorescence angiography and its multifunctional fusion. To address this gap, investigators plan to conduct a randomized controlled trial comparing the outcomes between the use of ICG Fluorescence lymph node Imaging combined with Fluorescence angiography (FIFA group) and conventional techniques (non-ICG group) in laparoscopic rectal cancer surgery. Specifically, investigators focus will be on the preservation of the left colic artery (LCA) and the clearance of No. 253 lymph nodes. The primary objectives of our study are to simplify surgical procedures, enhance surgical safety, and provide substantial evidence for the further promotion and adoption of this technique. ;
