[Chinese experts consensus on the prevention and treatment of complications caused by intraperitoneal perfusion chemotherapy for gastrointestinal tumors (2022 edition)].

Peritoneal metastasis is one of the common metastasis of gastrointestinal malignancy. Intraperitoneal chemotherapy (including hyperthermic intraperitoneal chemotherapy and intraoperative intraperitoneal chemotherapy) not only can effectively increase the peritoneal drug concentration, but also can reduce side effects of systemic chemotherapy. It can significantly prolong the long term survival of patients with peritoneal metastasis and improve the quality of life. In order to standardize the popularization and application of intraperitoneal chemotherapy, relevant professional committees have formulated expert consensus on intraperitoneal chemotherapy. However, there is no systematic guidance on the prevention and treatment of related complications of intraperitoneal chemotherapy. Under the guidance of the Complications Management Committee of the Colorectal Cancer Professional Committee of the Chinese Medical Association and the Colorectal Cancer Professional Committee of the Chinese Anti-cancer Association, we organized domestic experts in relevant fields to formulate this consensus according to the procedural specifications and relevant literature reports. This consensus aims to summarize the causes of common complications of intraperitoneal chemotherapy such as pneumonia, intraperitoneal hemorrhage, fever, peritonitis, ileus, intestinal dysfunction, anastomotic bleeding, anastomotic leakage, leakage or infection of perfusion tube, nausea and vomiting, myelosuppression, hepatic or nephritic dysfunction. After repeatedly soliciting the opinions of domestic authoritative experts and their discussion and modification, a consensus was formed to provide effective reference for the prevention and treatment of complications.腹膜转移是胃肠道肿瘤常见的转移方式之一，腹腔灌注化疗（包括腹腔热灌注化疗和术中腹腔化疗药物灌注）不仅能有效提高腹腔药物浓度，而且也能降低系统性化疗药物所导致的全身不良反应，能显著延长腹膜转移患者的生存时间，改善患者生活质量。为进一步规范腹腔灌注化疗的推广应用，有关专业委员会已制订了腹腔灌注化疗专家共识，但腹腔灌注化疗过程中相关并发症的防治未见系统性指导意见。本共识在中国医师协会结直肠肿瘤专业委员会并发症管理委员会和中国抗癌协会大肠癌专业委员会指导下，组织国内相关领域专家，根据国内外流程规范及相关文献报道，针对腹腔灌注化疗过程中出现的肺部感染、腹腔出血、发热、腹膜炎、肠梗阻、肠道功能障碍、吻合口出血、吻合口漏、灌注管口渗漏和感染、恶心呕吐、骨髓抑制以及肝肾功能障碍等常见并发症，在反复征求国内权威专家们的意见和讨论修改后形成一致意见，为并发症的预防和治疗提供参考。.
