Despite medical advances, the incidence of acute lower gastrointestinal bleeding (ALGIB) is gradually increasing in Asia and Vietnam, with many cases being severe. However, recent data on clinical features, interventions, and outcomes in Vietnam remain limited. This study aims to characterize the presentation, treatment, and outcomes of ALGIB in Vietnamese patients.
A retrospective and prospective cohort study was conducted on 222 patients aged 18 years and older with ALGIB at the Department of Gastroenterology, University Medical Center Ho Chi Minh City. Clinical characteristics, interventions, and adverse outcomes were recorded.
A total of 222 patients were included in the study, with a female-to-male ratio of 1.02 and a mean age of 63.7 years. Among them, 85.6% were admitted with symptoms of bright red blood per rectum, maroon-colored stool, or stool with clots. The most common causes of acute lower gastrointestinal bleeding were hemorrhoids (20.7%) and colonic diverticulosis (20.3%). The rates of blood transfusion, endoscopic intervention, radiologic intervention, and surgery were 38.7%, 19.4%, 2.7%, and 2.7%, respectively. Severe lower gastrointestinal bleeding was observed in 59 patients (26.6%). There were two in-hospital deaths (0.9%), one related to underlying comorbidities and one due to persistent, uncontrollable bleeding.

Overall, 26.6% of cases progressed to severe lower gastrointestinal bleeding.
尽管医学不断进步，但在亚洲及越南，急性下消化道出血（ALGIB）的发病率仍在逐渐上升，且许多病例病情严重。然而，越南近期关于临床特征、干预措施及治疗结果的数据仍然有限。本研究旨在描述越南患者急性下消化道出血的临床表现、治疗及结果。
对胡志明市大学医学中心胃肠病科收治的222例18岁及以上的急性下消化道出血患者进行回顾性和前瞻性队列研究。记录临床特征、干预措施及不良结局。
本研究共纳入222例患者，男女比例为1.02，平均年龄为63.7岁。其中，85.6%的患者因直肠排出鲜红色血液、暗红色大便或带血块大便的症状入院。急性下消化道出血最常见的病因是痔疮（20.7%）和结肠憩室病（20.3%）。输血、内镜干预、放射介入及手术的比例分别为38.7%、19.4%、2.7%和2.7%。59例患者（26.6%）出现严重下消化道出血。有2例住院死亡（0.9%），1例与基础合并症有关，1例因持续性、难以控制的出血死亡。
