Summary

Fluorescence-guided surgery using indocyanine green can visualize the complex and diverse lymph node drainage structures for each patient and help determine the extent of dissection of the D3 lymph node tailored to the patient. However, since fluorescence lymph node mapping (FLNM) is still being conducted only at some institutions for research purposes and is limited to reporting the results of small-scale studies of patients, a large-scale multi-center study was conducted to verify the clinical-oncological effects of FLNM. Research is needed.

Therefore, this study used real-time fluorescence lymph node mapping (FLNM) to determine the extent of D3 lymph node dissection when performing right hemicolectomy and D3 lymph node dissection in patients with locally advanced right-sided colon cancer and to safely remove extensive lymph nodes. We aim to evaluate whether the dissection procedure is safe and beneficial in terms of clinical oncology.

Conditions

  • Right Hemicolectomy

Interventions

DRUG

Indocyanine green (ICG) injection for intraoperative lymph node imaging

Indocyanine Green (ICG) is used to guide the extent of D3 lymph node dissection during right hemicolectomy. After informed consent, participants randomized to the experimental group undergo bowel preparation and receive an endoscopic submucosal injection of ICG (0.25 mg/ml in saline) at two sites adjacent to the tumor one day prior to surgery. During surgery, near-infrared laparoscopic or robotic imaging systems detect the fluorescence emitted by ICG, guiding targeted D3 lymph node dissection at the origins of the ileocolic artery (ICA) and middle colic artery (MCA).

OTHER

Standard Right Hemicolectomy (Non-ICG)

Participants in the control group undergo standard right hemicolectomy with D3 lymph node dissection without the use of Indocyanine Green (ICG) or fluorescence imaging. The extent of dissection is determined by conventional anatomical landmarks and the surgeon's clinical judgment.
