结直肠癌是我国常见的消化道恶性肿瘤之一，外科手术仍是其主要治疗手段。随着腹腔镜及各类新术式的快速发展，吻合器在结直肠手术消化道重建中的应用日益广泛，但对电动智能吻合器选型、钉仓量化匹配、术中多模态质量评估、标准化操作流程等临床亟待明确的问题尚缺乏统一标准。为此，中国抗癌协会大肠癌专业委员会组织国内相关领域专家制定本共识。共识从吻合器应用前全身状况及局部组织评估、肠道切割与吻合操作标准、吻合器选择与使用规范三个维度，系统阐述了结直肠癌手术肠管切割吻合及重建的规范化流程，涵盖围手术期全身状态优化、局部组织血供与张力评估、肿瘤切缘标准、吻合方式选择、术中吻合质量评估、手工加固缝合指征与技术、吻合器型号与钉仓选择原则以及电动吻合器标准化操作技术等核心内容，共形成9条推荐意见。本共识旨在为结直肠手术中吻合器的规范化应用提供循证指导，以期降低吻合口漏、出血、狭窄等术后并发症风险，提高手术安全性。

Colorectal cancer is one of the most common malignant gastrointestinal tumors in China, and surgery remains its primary treatment modality. With the rapid development of laparoscopy and various novel surgical approaches, staplers are being increasingly used in digestive tract reconstruction during colorectal surgery. However, there is still a lack of unified standards for the scientific selection and standardized use of stapling instruments. To address this, the Colorectal Cancer Committee of the China Anti-Cancer Association organized domestic experts in relevant fields to formulate this consensus. The consensus systematically elaborates the standardized procedures for bowel transection, anastomosis, and reconstruction in colorectal cancer surgery from three dimensions: preoperative assessment of systemic conditions and local tissues, standards for bowel transection and anastomosis, and selection and usage specifications for staplers. It covers core contents including optimization of perioperative systemic status, assessment of local tissue blood supply and tension, tumor margin criteria, selection of anastomotic methods, intraoperative quality evaluation of the anastomosis, indications and techniques for hand-sewn reinforcement suturing, principles for selecting stapler types and cartridge sizes, and standardized operating techniques for powered staplers, forming a total of 9 recommendations. This consensus aims to provide evidence-based guidance for the standardized application of staplers in colorectal surgery, so as to reduce the risk of postoperative complications such as anastomotic leakage, bleeding, and stricture, and to improve surgical safety.
