Successful application of ICG fluorescence imaging technology in rectal neuroendocrine tumor liver metastasisS

We report the use of indocyanine green fluorescence imaging technology to assist the resection of rectal neuroendocrine tumors with liver metastases. The liver metastases of rectal neuroendocrine tumors show strong fluorescent signals, the tumor borders are clear, and there is no fluorescence at the resection margin, indicating that the tumor has been completely removed. Postoperative pathology also confirmed that the tumor margin was negative. ICG fluorescence imaging has great potential in assisting the resection of liver metastases of neuroendocrine tumors, and at the same time is able to assist in judging the removal of the tumor.
