Intersphincteric resection (ISR) is the ultimate sphincter-preserving surgical technique for low rectal cancer. Accurate preoperative diagnosis and staging, appropriate selection of surgical approaches and technique, standardized perioperative management, and postoperative rehabilitation are the keys to ensuring the oncological effect and functional preservation of ISR. To date, there is still a lack of standardized guidance on the clinical implementation of ISR in China. Therefore, based on the latest evidence from literature, expert experience, and the intervention situation in China, the Chinese Society of Colorectal Surgery, Chinese Society of Surgery, Chinese Medical Association organized domestic experts in colorectal surgery to discuss and produce "Chinese expert consensus on intersphincteric resection for low rectal cancer (2023 edition)". This consensus focuses on definition, classification, related pelvic anatomy, operational techniques, postoperative complications, and long-term oncological and functional outcomes, and aims to guide the standardized clinical practice of ISR in the operation of low rectal cancer in China.
括约肌间切除术（ISR）是低位直肠癌保肛手术的终极技术。准确的术前诊断与分期、手术方式和技术的恰当选择、规范的围手术期管理以及术后康复是确保ISR肿瘤治疗效果和功能保留的关键。目前，我国ISR临床实施仍缺乏规范指导。因此，中国结直肠外科学会、中华医学会外科学分会、中华医学会组织国内结直肠外科专家，基于文献最新证据、专家经验及我国干预情况进行讨论，制定了“中国低位直肠癌括约肌间切除术专家共识（2023版）”。本共识聚焦于定义、分类、相关盆腔解剖、手术技术、术后并发症以及长期肿瘤学和功能结局，旨在指导我国低位直肠癌手术中ISR的规范临床实践。
