During the period of the study, lower GI bleeding patients comprised a constant 1.6% of the total admitted patients at Hanyang University Hospital annually. There were no statistically significant changes according to year. The 970 cases were classified as follows: hemorrhoid and anal fissure 65.5%, malignant neoplasm 21.1% (rectal cancer 16.9%, sigmoid colon cancer 3.3%, anal cancer 0.9%), benign neoplasm 4.2%, ulcerative colitis 3.3%, infectious colitis 2.3%, ischemic colitis 1.8%, radiation colitis 1.3%, diverticulosis 0.3%, and others 0.2%. Ulcerative colitis and rectosigmoid cancer showed increasing trends, while other disease groups showed no change in the occurrence rate. Hemorrhoid and anal fissure developed mostly in the 30s age group, benign polyp and ulcerative colitis in the 40s age group, malignant neoplasm in the 50s age group, and ischemic colitis and radiation colitis in the 60s age group. There was no sexual predominance of lower GI bleeding. About 10% of the patients admitted to the hospital needed transfusions, particularly patients with ulcerative colitis (21.9%) and radiation colitis (23.1%). 20.2% of the patients improved with supportive measures and medical treatment and 79.8% underwent surgical operation. In particular, 51.2% of the patients with benign neoplasm underwent polypectomies.
在研究期间，下消化道出血患者每年占汉阳大学医院总住院患者的1.6%，且各年份之间无统计学显著变化。970例患者分类如下：痔疮和肛裂占65.5%，恶性肿瘤占21.1%（直肠癌占16.9%，乙状结肠癌占3.3%，肛管癌占0.9%），良性肿瘤占4.2%，溃疡性结肠炎占3.3%，感染性结肠炎占2.3%，缺血性结肠炎占1.8%，放射性结肠炎占1.3%，憩室病占0.3%，其他占0.2%。溃疡性结肠炎和直肠乙状结肠癌发病率呈上升趋势，而其他疾病组发病率无变化。痔疮和肛裂多发生于30多岁年龄组，良性息肉和溃疡性结肠炎多发生于40多岁年龄组，恶性肿瘤多发生于50多岁年龄组，缺血性结肠炎和放射性结肠炎多发生于60多岁年龄组。下消化道出血无性别差异。约10%的住院患者需要输血，尤其是溃疡性结肠炎患者（21.9%）和放射性结肠炎患者（23.1%）。20.2%的患者通过支持治疗和药物治疗病情改善，79.8%的患者接受了手术治疗。特别是，51.2%的良性肿瘤患者接受了息肉切除术。
