Application of Indocyanine Green Labeled Fluorescent Laparoscopy in Proximal Gastric Cancer

Sponsor: Guangyong Zhang

Summary

Recently, laparoscopic gastrectomy has been gradually accepted by surgeons worldwide for gastric cancer treatment. Complete dissection of the lymph nodes and the establishment of the surgical margin are the most important considerations for curative gastric cancer surgery. Previous studies have demonstrated that indocyanine green (ICG)-traced laparoscopic gastrectomy significantly improves the completeness of lymph node dissection. However, it remains difficult to identify the tumor location intraoperatively for gastric cancers that are staged ≤T3. Here, the investigatorsinvestigated the feasibility of ICG fluorescence for lymph node mapping and tumor localization during totally laparoscopic distal gastrectomy.Preoperative and perioperative data from consecutive patients with gastric cancer who underwent a laparoscopic proximal gastrectomy were collected and analyzed. The investigators want to know if near-infrared fluorescence imaging with ICG can be successfully used in laparoscopic proximal gastrectomy, and if it contributes to both the completeness of D2 lymph node dissection and confirmation of the gastric transection line. The application of ICG labeled near infrared imaging fluorescence laparoscopic technology is still in the stage of exploration and experience accumulation, and it needs to be comprehensively evaluated through a large number of prospective randomized controlled studies.
