About

Jesper N. Andersen is a colorectal surgeon and researcher whose work focuses on improving surgical outcomes in rectal cancer treatment, particularly through the use of advanced intraoperative imaging. His primary research areas include anastomotic perfusion assessment, fluorescence-guided surgery, and the prevention of anastomotic leakage—a serious complication following low-anterior resection. Andersen’s major contribution lies in rigorously evaluating the clinical utility of indocyanine green fluorescent imaging (ICG-FI) for real-time blood flow assessment during robotic-assisted surgery. His landmark multicenter study on interobserver variation in perfusion assessment (2023, 20 citations) critically examined the reliability and consistency of this emerging technology, providing essential evidence for its standardization and broader adoption. By highlighting the variability in how surgeons interpret ICG-FI, his work has directly informed efforts to improve training and decision-making in the operating room. Andersen’s research bridges the gap between technological innovation and practical surgical application, helping to reduce complication rates and improve patient recovery. His findings are increasingly cited in guidelines and subsequent studies on fluorescence-guided colorectal surgery, marking him as a key voice in the push toward safer, more precise minimally invasive procedures.
