恶性肿瘤腹腔内广泛转移失去了手术机会的中晚期胃肠道恶性肿瘤，以及切除术后腹腔内复发和肝转移的处理至今仍是棘手问题。在我国进展期消化系恶性肿瘤仍占临床消化道癌的80％以上，5年生存率很低，主要原因是术后有较高的腹腔内复发率，50％以上5年内死于腹膜转移[1]。腹腔内 The widespread metastasis of malignant tumors in the peritoneal cavity and the loss of surgical opportunities for advanced gastrointestinal malignancies, and the treatment of intra-abdominal recurrence and liver metastasis after resection remain problematic. Progressive digestive malignancies in China still account for more than 80% of clinical gastrointestinal cancers. The 5-year survival rate is very low. The main reason is that there is a high postoperative intra-abdominal recurrence rate, and 50% of patients died of peritoneal metastasis within 5 years [ 1]. Intraperitoneal
