腹膜转移癌多由进展期胃肠道癌肿和卵巢癌等恶性肿瘤的腹腔内播散和转移所致,属于癌肿演进过程中的终末阶段。临床上这些患者往往伴有不同程度的恶性腹水和胃肠道并发症等,病情发展快,预后差,治疗相当困难。近年来对腹膜癌转移的外科治疗有了一些新的认识和发展,对于一些恶性程度低、肿瘤分化较好的患者仍可进行以减瘤性腹膜切除术为主的综合性治疗,并可取得较好的临床疗效,现就其主要有关的内容作一综合分析。 Peritoneal metastases are mostly caused by intra-abdominal dissemination and metastasis of malignant tumors such as advanced gastrointestinal cancers and ovarian cancers. They are the final stages in the evolution of cancer. Clinically these patients are often accompanied by varying degrees of malignant ascites and gastrointestinal complications, etc. The disease develops rapidly, the prognosis is poor, and the treatment is quite difficult. In recent years, there have been some new understandings and developments in the surgical treatment of peritoneal cancer metastasis. For some patients with low malignancy and well-differentiated tumors, comprehensive treatment based on tumor-reducing peritoneal resection can still be performed. For better clinical efficacy, a comprehensive analysis of its main relevant content is now conducted.
