BACKGROUND: The indocyanine green fluorescence imaging (ICG-FI) technique is increasingly being used in laparoscopic colorectal surgery for lymph node mapping. However, there is no definitive standard regarding whether the application of this technique can significantly increase the detection rate of metastatic lymph nodes and improve long-term prognosis. METHODS: PubMed, Embase, Web of Science, and Cochrane Library databases were searched to include studies including ICG-FI in laparoscopic colorectal surgery. Data on the detection rate of lymph nodes, metastatic rate of ICG-positive nodes, and long-term clinical outcomes were extracted following inclusion criteria. RESULTS: Eighteen studies with a total of 1552 patients 922 with ICG-guided laparoscopic and 630 without ICG technique were finally included. Clinical stage II/III colorectal tumors were the most commonly studies types. The patients using the ICG-FI technique had more harvested lymph nodes (weighted mean: 23.5 vs. 18.9; WMD = 4.6; p < 0.00001) during dissection but a lower metastasis rate of ICG-positive nodes (61/218 [28%] vs. 96/333 [28.9%]; OR = 1.45; p = 0.08). Compared with conventional laparoscopic colorectal surgery, additional ICG-FI technique did not improve the 3 year overall survival rate (272/289 [94.1%] vs. 269/289 [93.1%]; OR = 1.19; p = 0.61), relapse-free survival (246/289 [85.1%] vs. 249/289 [86.2%]; OR = 0.92; p = 0.72), and local recurrence rate (22/289 [7.6%] vs. 28/289 [9.7%]; OR = 0.77; p = 0...
