Recurrence of gastric cancer with total resection of anastomosis can be treated with surgical resection or chemotherapy according to the condition. If gastric cancer recurrence is confirmed by gastroscopy, X-ray barium fluoroscopy, CT, etc., and resection is still possible even if there is invasion of neighboring organs, and when serious cardiac or pulmonary insufficiency, severe malnutrition and systemic extensive metastasis are excluded, then the patient should be positively treated with timely surgery to perform total resection of residual stomach or partial resection of residual stomach. For patients who cannot be resected, postoperative chemotherapy with drug pump can be selectively inserted through the feeding vessels of the residual stomach during the operation, and some people also put chemotherapy tubes through the peritoneal cavity for postoperative intraperitoneal injection of chemotherapy, which can also play a certain role in some cases. For patients with recurrent gastric cancer that cannot be resected, chemotherapeutic drugs (such as mitomycin, doxorubicin, cisplatin, etc.) can be injected into the abdominal artery or the left gastric artery according to the patient’s physical condition and tolerance after wound healing and under the digital imaging examination.
