2019年美国消化内镜学会《慢性放射性直肠病出血内镜诊治指南》解读

The interpretation of 2019 ASGE guideline on the role of endoscopy for bleeding from chronic radiation proctopathy

放射性直肠病是盆腔恶性肿瘤患者接受放疗后导致的直肠放射性损伤,分为急性和慢性。慢性放射性直肠病可出现直肠出血等并发症,严重影响患者生活质量。目前,内镜检查已成为诊断和治疗慢性放射性肠病出血的主要方法。2019年10月美国消化内镜学会发布了《慢性放射性直肠病出血内镜诊治指南》,该指南阐述了氩离子凝固术、双极电凝术、热探头、射频消融术、冷冻消融术等内镜治疗方法治疗慢性放射性直肠病出血的有效性和安全性。本文对其进行解读,以期为临床医师治疗慢性放射性直肠病出血提供参考。

Radiation proctopathy, which can be categorized as acute and chronic, is defined as the radiation damage to the rectum caused by radiation therapy in patients with pelvic malignancies. Chronic radiation proctopathy can cause complications such as rectal bleeding, which severely affects patients’ quality of life. At present, endoscopic therapy has become the primary method for diagnosis and treatment of bleeding from chronic radiation proctopathy.In October 2019, the American Society for Gastrointestinal Endoscopy(ASGE) published "ASGE guideline on the role of endoscopy for bleeding from chronic radiation". The guideline described the effectiveness and safety of different endoscopic therapies such as argon plasma coagulation, bipolar electrocoagulation, heater probe, radiofrequency ablation, cryoablation, etc. in the treatment of bleeding from chronic radiation. This paper interprets it to provide references for clinicians in the treatment of bleeding from chronic radiation.
