Abstract    Chronic radiation proctitis (CRP) is a common complication of radiotherapy for patients with pelvic malignancies. Standardization in the diagnosis and treatment of CRP is extremely important to improve the quality of patients’ life. The American Society of Colon and Rectal Surgeons (ASCRS) published the first international clinical practice guidelines of CRP in 2018. It covered the prevention, diagnosis and therapy of CRP, mainly summarized the existing common treatment modalities and gave the classification of recommendation grade, which provided guidelines for clinicians to make standard diagnosis and treatment of CRP. However, the description of the application process and dosage of CRP diagnosis and treatment method is not specific enough, and high-quality clinical research is needed to draw conclusions to better guide clinical practice.

摘要： 慢性放射性直肠炎是盆腔恶性肿瘤行放射治疗的常见并发症，对其进行规范诊治对改善病人生活质量至关重要。2018年，美国结直肠外科医师协会发布了第1版《慢性放射性直肠炎临床实践指南》，其内容涵盖了慢性放射性直肠炎的预防、诊断及治疗策略，重点论述了现有的常见治疗手段，并对其进行分级推荐，为临床医生规范诊治慢性放射性直肠炎提供了依据。但其对CRP诊疗方法的应用流程和剂量等描述不够具体，尚需高质量的临床研究来得出结论，以更好的指导临床。
