*3.3.9 The affinity of ICG in the detection of colorectal peritoneal carcinomatosis*

Peritoneal metastases can appear in 30–40% of patients with colorectal cancer and in a quarter of the patients might be the cause of death. ICG-guided surgery was able to detect additional lesions, and some studies reported up to 21.4% with a direct impact on modifying the surgical resection technique (**Figure 16**).
