[Chinese expert consensus on intersphincteric resection for low rectal cancer (2023 edition)].

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.经括约肌间切除术（ISR）是针对低位直肠癌的极限保肛术式，准确的术前诊断评估、合理的手术方式选择和操作、规范的围手术期管理和康复锻炼，是保证ISR肿瘤根治性和功能保留的关键。然而，目前国内关于ISR的临床实施仍缺乏规范化体系的指导。据此，中华医学会外科学分会结直肠外科学组组织国内专家，通过借鉴国内外最新指南及研究证据，结合国内实际情况，制定了《低位直肠癌经括约肌间切除术中国专家共识（2023年版）》，从ISR的定义、分类、相关局部解剖、操作技术、术后并发症、远期肿瘤学和功能学预后等方面进行阐述，以期促进我国低位直肠癌ISR的规范化开展。.
