目的 汇总分析肝硬化患者消化道出血风险预测模型，为今后模型的建立和优化提供参考。方法   系统检索中国知网、维普、PubMed数据库在2025年4月22日前公开发表的所有肝硬化患者消化道出血风险预测模型，按纳入标准筛选文献，对最终纳入文章分析摘录并系统汇总，包括模型特征、危险因素及模型预测评估效果等信息。结果   共检索3 603篇预测模型相关研究论文，最终纳入30篇，其中中国27篇、韩国1篇、印度1篇、埃及1篇。22项研究收集了肝硬化病因，其中病毒性肝病最多（72.94%，2 922/4 006），药物性肝病及非酒精性脂肪性肝病最少（均为0.02%，1/4 006）。在研究类型上，有28篇单中心研究，2篇为多中心研究，其中有12个模型未进行验证，只有1个模型进行了外部验证，其余模型只进行了内部验证，曲线下面积（AUC）范围0.680~0.994。根据模型纳入因素特点，分为血常规指标、凝血指标、生化指标、影像学指标、复合指标、其他指标共6种，其中纳入因素最多为影像学指标，最少为凝血指标。在纳入危险因素中，第1位为门静脉直径，第2位为血小板计数，第3位为血红蛋白水平及脾脏硬度，所有因素中与脾脏相关的指标最多。结论   肝硬化患者消化道出血风险预测模型研究质量有待提升，影像学指标应用最广，脾脏相关指标重要性突出，门静脉直径、血小板计数、血红蛋白水平及脾脏硬度为最常用的危险预测因素。

       Objective  To  summarize and analyze the  prediction models for gastrointestinal  bleeding  risk in  patients with cirrhosis，providing references for the establishment and optimization of future models．Methods  A systematic search was conducted in CNKI，VIP，and PubMed for all published prediction models for gastrointestinal bleeding risk in patients with cirrhosis before April 22，2025．Articles were screened according to the inclusion criteria，and the finally included articles were analyzed and summarized，including model characteristics，risk factors，and model prediction evaluation effects．Results  A total of 3 603 related research papers on prediction models were initially retrieved，and 30 were finally included，with 27 from China，one from South Korea，one from India，and one from Egypt．Among the 22 studies that collected the etiology of cirrhosis，viral hepatitis was the most common（72.94%，2 922/4 006），while drug-induced liver disease and non-alcoholic fatty liver disease were the least common（0.02%，1/4 006）．In terms of study type，28 were single-center studies and two were multicenter studies．Among them，12 models were not validated，only one model was externally validated，and the rest were only internally validated，with an area under the curve range of 0.680-0.994．According to the characteristics of the factors included in the models，they were divided into six types of indicators：blood routine，coagulation，biochemistry，imaging，composite，and others，among which imaging indicators were the most common and coagulation indicators were the least．In the included risk factors，the first was portal vein diameter，the second was platelets count，and the third was hemoglobin level and spleen stiffness，with the most factors related to the spleen．Conclusions  The quality of studies on prediction models for gastrointestinal bleeding risk in cirrhosis patients needs to be improved．Imaging indicators are the most widely used，and spleen-related indicators are of prominent importance，with portal vein diameter，platelets count，hemoglobin level，and spleen stiffness being the most commonly used risk prediction factors．

目的 上消化道出血发作急、变化快,具有较高的危险性,本研究目的在于分析急性上消化道出血患者的临床特征及危险因素,为临床诊治提供参考。方法 将2019年1月—2021年2月年我院的242例疑似急性上消化道出血患者作为研究对象,收集患者的年龄、性别、是否有长期抽烟史、饮酒史,是否有合并症以及并发症等一般资料,运用单因素分析其临床特征,运用多因素Logistic回归分析其独立危险因素。结果 患者年龄、长期饮酒史、消化性溃疡、门脉高压、急性胃黏膜病变、服用阿司匹林(ASA药物)、Hp感染等临床特征与急性上消化道出血具有相关性,与患者的性别、长期抽烟史不具有相关性;年龄、消化性溃疡、门脉高压、服用ASA药物、Hp感染是急性上消化道出血的危险性因素。结论 急性上消化道出血病势程度较重,死亡率高,出血需及时针对性治疗;对于急性上消化道出血高危患者,严密监测病情变化,评估其风险系数。

Objective Upper gastrointestinal bleeding has a high risk because of its rapid change. The purpose of this study is to analyze the clinical characteristics and risk factors of patients with acute upper gastrointestinal bleeding, so as to provide reference for clinical diagnosis and treatment. Methods A total of 242 patients with suspected acute upper gastrointestinal bleeding in our hospital from January 2019 to February 2021 were selected as the research objects. The general data such as patients' age, gender, whether they had a long-term history of smoking or drinking, whether they had complications and data of complications were collected. The clinical characteristics were analyzed by univariate analysis, and the independent risk factors were analyzed by multivariate Logistic regression analysis. Results Age, long-term drinking history, peptic ulcer, portal hypertension, acute gastric mucosal lesions, taking aspirin (ASA drugs), Hp infection and other clinical characteristics were correlated with acute upper gastrointestinal bleeding, but gender and long-term smoking history were not. Age, peptic ulcer, portal hypertension, taking ASA drugs and Hp infection were the risk factors of acute upper gastrointestinal bleeding. Conclusion The acute upper gastrointestinal bleeding is a serious disease, with high mortality, and the bleeding needs timely targeted treatment. For patients with high-risk acute upper gastrointestinal bleeding, closely monitor the changes of the disease and evaluate the risk coefficient are needed.
