腹膜转移是胃癌病人最常见的死亡原因，一旦浆膜受侵犯，即使施行了根治性手术，仍有50％的病人出现腹膜转移。为了正确预测腹膜的转移，作者通过对胃癌病人术中进行腹腔灌洗查找恶性细胞，从而确立腹腔中游离肿瘤细胞与病人肿瘤复发的关系。方法1975.4～1997.5间，作者对1297 Peritoneal metastasis is the most common cause of death in patients with gastric cancer, once the serosa invasion, even with the implementation of radical surgery, there are still 50% of patients with peritoneal metastases. In order to correctly predict the peritoneal metastasis, the author through the intraperitoneal laparoscopic operation of gastric cancer patients to find the malignant cells, so as to establish the relationship between the free tumor cells in the abdominal cavity and the patient’s tumor recurrence. Methods From 1975.4 to 1997.5, the author of 1297
