Trial Identification

Brief Title: Effect of CNSI vs. ICG in Lymph Node Tracing During Gastrectomy

Official Title: A Prospective Randomized Controlled Study of the Efficacy of Carbon Nanoparticles Versus Indocyanine Green in Robotic or Laparoscopic Gastrectomy

Study ID: NCT05229874

Conditions

Gastric Cancer

Interventions

carbon nanoparticles

Indocyanine green

Study Description

Brief Summary: The purpose of this study is to assess the efficacy and safety of carbon nanoparticle suspension injection and indocyanine green tracer-guided lymph node dissection during gastrectomy in patients with gastric cancer

Detailed Description: Da Vinci robot surgery XI system has fluorescence imaging function, which can realize indocyanine green lymph node tracking navigation technology in the operation. At the same time, the lymph node tracking effect of nano carbon suspension injection is not affected by equipment. The flexible mechanical arm of Da Vinci robot combined with the application of lymph node tracing technology makes the lymph node dissection of gastric cancer surgery more thorough, and also reduces the difficulty of surgery. Indocyanine green navigational lymphadenectomy can also be performed by fluorescence laparoscopy. By comparing the two tracer techniques, the lymph node tracer technique which is more suitable for robot or laparoscopic surgery system is selected to provide help and choice for clinical surgeons.
