[Palliative Surgery for Peritoneal Metastasis of Gastric Cancer]

Different surgical interventions can be applied for the treatment of peritoneal metastasis of gastric cancer according to the extent of metastasis. Gastrectomy is a consensus-based standard treatment for gastric cancer with minimal peritoneal metastasis, although there is a lack of established evidence. Conversely, gastrectomy for an intermediate to high extent of peritoneal metastasis is not considered a suitable treatment based on the results of the JCOG0705 study. Colostomy or bypass surgery is often performed for intestinal stenosis due to peritoneal metastasis to palliate symptoms and allow the introduction of chemotherapy.
