Abstract: Indocyanine green (ICG) fluorescence has increasingly been used in gastrointestinal surgery as a tool for intraoperative assessment of tissue perfusion, contributing to the prevention of postoperative complications, particularly anastomotic leakage. Objective: To analyze the available scientific evidence regarding the use of ICG fluorescence in gastrointestinal surgery, with emphasis on tissue perfusion assessment and associated surgical outcomes. Methods: An integrative literature review was conducted following the PRISMA 2020 recommendations. Searches were performed in PubMed/MEDLINE, Scopus, Embase, and the Virtual Health Library (VHL) using descriptors related to ICG fluorescence and gastrointestinal surgery. Studies published between 2020 and 2023, available in full text and addressing the use of ICG in gastrointestinal procedures, were included. Eight studies met the eligibility criteria and composed the final sample. Results: The analyzed studies demonstrated that ICG fluorescence provides a more accurate assessment of intestinal perfusion compared with conventional methods. Evidence indicated a reduction in anastomotic leakage rates, improved intraoperative decision-making, and potential optimization of surgical outcomes. Additional applications were identified in oncologic, laparoscopic, and robotic procedures. However, limitations remain regarding the lack of standardized protocols and methodological heterogeneity among studies. Conclusion: Indocyanine green fluorescence represents a promising tool in gastrointestinal surgery, with the potential to improve tissue perfusion assessment and reduce complications related to intestinal anastomoses. Despite favorable results, further studies are needed to standardize the technique and support its routine incorporation into surgical practice.
