Lower gastrointestinal bleeding is common and can result from several colonic causes including diverticulosis, arteriovenous malformations, ischemia, inflammatory bowel disease, infectious colitis, neoplasm, postpolypectomy, and anastomotic and radiation proctitis. Following resuscitation and evaluation, colonoscopy can be used for diagnosis and treatment. Most physicians prescribe a bowel preparation for their patients. Therapeutic options include injection, coagulation (monopolar or bipolar cautery, argon plasma coagulator), and mechanical (clips, bands, detachable loops) devices.
下消化道出血很常见，可由多种结肠病因引起，包括憩室病、动静脉畸形、缺血、炎症性肠病、感染性结肠炎、肿瘤、息肉切除术后、吻合口炎和放射性直肠炎。在复苏和评估之后，结肠镜检查可用于诊断和治疗。大多数医生会为患者开出肠道准备的医嘱。治疗选择包括注射、凝血（单极或双极电灼、氩离子凝固器）以及机械（夹子、套圈、可分离套环）器械。
