Summary

Indocyanine green NIR imaging is valuable for lymph node dissection in D3 radical surgery for rectal cancer. It can guide the intraoperative improvement of lymph node dissection based on the preservation of LCA and peripheral autonomic nerves of IMA. This not only reduces the occurrence of postoperative complications and promotes rapid postoperative recovery, but also provides a more precise and individualized comprehensive treatment plan for patients after surgery. In addition，this trial also demonstrated that ICG is safe and feasible for use in rectal cancer

Conditions

  • Indocyanine Green

Interventions

OTHER

non-ICG

Laparoscopic radical resection of rectal cancer was performed routinely without ICG injection. The separation should extend from the center to the left, reaching the left paracolic sulcus lateral to the genital vessels. The Superior hypogastric nerve is protected by freeing it at the angle of the common iliac artery on both sides, afterwards, the vessel is free along the surface of the plexus from caudal to cephalic side to reach the root of the IMA. Switching lymph node visualization patterns. Based on the operator's experience and the extent of lymph node visualization, the lymph nodes at the root of the IMA were removed with an ultrasonic knife . The dissection continues caudally along the IMA, preserving the arterial sheath. Expose the left colonic artery, superior rectal artery, and sigmoid artery, maximum preservation of the IMA peripheral plexus while clearing their surrounding lymph nodes.

DRUG

ICG

Dilute ICG to 2.5 mg/ml with its accompanying sterilized water for injection. Slow injection with a 1ml syringe in 4 parts of the tumor，Inject 0.25ml per site . Procedure started after lymph node visualization.The operation was consistent with the control group.
