Indocyanine Green-guided Lymphadenectomy in Laparoscopic Total Mesorectal Excision for Low Rectal Cancer After Neoadjuvant Chemoradiotherapy ((GreenEye-CRC))

The goal of this clinical trial is to assess the number of harvested locoregional lymph nodes in rectal cancer patients undergoing laparoscopic total mesorectal excision and indocyanine green (ICG)-guided lymphoadenectomy after neoadjuvant chemoradiation. The main questions it aims to answer are:

  • Does the use of ICG increase the total number of harvested lymph nodes?
  • Does the use of ICG increase the number of harvested extra-mesorectal lymph nodes?

Participants will intraoperatively receive a trans-anal administration of ICG near to rectal cancer; during laparoscopic surgery, ICG-fluorescent nodes beyond the mesorectum will be separately excised and sent for pathology. A comparison will be performed with a recent cohort of patients affected by rectal cancer treated with standard surgery without the use of ICG.
