(en) Gastric cancer is the fifth most prevalent cancer and the third most common cause of cancer-related deaths globally1. Gastric cancer frequently metastasizes to the peritoneal cavity. The incidence of peritoneal metastases at the time of diagnosis, including free cancer cells in peritoneal washings, ranges from 15% to 32%, and its presence is associated with a poor prognosis. Due to the low sensitivity of conventional imaging such as CT or PET-CT for peritoneal metastases, staging laparoscopy is performed to exclude small-volume macroscopic peritoneal dissemination or free cancer cells, and to assess the local resectability of the tumour.
