Background: Anastomotic leakage after a colorectal resection results in devastating consequences for patients. Indocyanine green fluorescence angiography is a modality to visualize vascular perfusion at the anastomotic site and can help surgeons decide the viability of the anastomosis. We performed this systematic review and meta-analysis to evaluate the efficacy of indocyanine green fluorescence angiography in decreasing anastomotic leakage. Methods: PubMed, Web of Science, Embase, and the Cochrane Library were searched to identify studies comparing the use of indocyanine green fluorescence angiography versus standard care on rates of anastomotic leakage. Data were pooled with the Mantel-Haenszel method and analyzed based on a random-effects model to estimate the pooled odds ratio and 95% confidence interval. The heterogeneity of studies was evaluated using I2 statistic. Results: Twenty studies were included in this meta-analysis of 5,498 patients. The pooled estimate of the odds ratio was 0.46 (95% confidence interval 0.34–0.62; P
