Near-infrared Imaging With Indocyanine Green for Detection of Peritoneal Metastases for Gastric Adenocarcinoma.

Peritoneal disease at initial presentation for patients with gastric adenocarcinoma (GA) is frequent, with 15-31% of patients presenting with peritoneal metastases (PM) at surgical exploration. The prognosis of patients with PM is poor, overall survival (OS) ranging from 8 to 13 months, reinforcing the importance of optimal patient selection before surgical management of GA. Indocyanine Green (ICG) fluorescence imaging for intraoperative detection of PM has been described in recent literature as a useful tool in patients undergoing cytoreductive surgery (CRS) with hyperthermic intraperitoneal chemotherapy (HIPEC) for peritoneal malignancies to increase the detection of PM during surgery. However, the role of ICG for patients with GA, and its role during diagnosic laparoscopy (DL), remain unknown.
