Flexible sigmoidoscopy has emerged as a vital tool for the purpose of assessing colorectal anastomoses: a procedure that can play a crucial role in reducing postoperative complications. The present technical note aims at describing a comprehensive strategy for the perioperative evaluation of colorectal anastomoses integrity. An endoscopic grading system is utilized to categorize findings, ensuring consistency and external validity. Postoperative flexible sigmoidoscopy can evaluate anastomotic integrity using a classification system, thereby facilitating informed decision-making and enabling targeted local treatment options. Additionally, flexible sigmoidoscopy can be carried out post-discharge from the hospital for further assessment of late-onset anastomotic leakage. While a consensus on the utility of flexible sigmoidoscopy is yet to be established, its potential to improve surgical decision-making is evident.

结肠镜检查已成为评估结直肠吻合口完整性的重要工具：这一程序可以在减少术后并发症方面发挥关键作用。本技术注释旨在描述围手术期评估结直肠吻合口完整性的全面策略。使用内镜分级系统对发现结果进行分类，以确保一致性和外部有效性。术后结肠镜检查可以利用分类系统来评估吻合口的完整性，从而促进知情决策并提供针对性的局部治疗选择。此外，在出院后可以通过结肠镜检查进一步评估迟发性吻合口漏。虽然关于结肠镜检查实用性的共识尚未达成，但其改善外科手术决策的潜力显而易见。
