              发性出血风险的预测评分系统。方法:回顾性分析2016年2月—2020年11月在苏州大学附属第一医院消化科行ESD术治疗
              的296例EGC(包括高级别上皮内瘤变)患者的资料,经多因素分析找出影响EGC ESD术后迟发性出血的独立危险因素,并根
              据其回归系数对独立危险因素进行赋分,建立术后迟发性出血风险预测评分系统,且根据评分及迟发性出血发生率,绘制受试

              危险分层。结果:病灶黏膜下层纤维化(OR=12.163,95%CI:2.735~54.102)、切除标本直径>4 cm(OR=19.091,95%CI:3.726~
              97.819)、使用抗凝药和/或抗血小板药(OR=5.334,95%CI:1.013~28.088)是EGC ESD 术后发生迟发性出血的独立危险因素(P
              均<0.05);评分系统:使用抗凝药和/或抗血小板药为1分,病灶黏膜下层纤维化为2分,切除标本直径>4 cm为2分。根据评
              分和迟发性出血发生率绘制ROC曲线,其AUC值为0.85(95%CI:0.753~0.947,P<0.001),最佳截断值为1.5分,以评分0~1分
              定义为低危组,评分2~5分定义为高危组,评分为低危组者ESD术后迟发性出血发生率为1.03%(2/194),评分为高危组者ESD
              术后迟发性出血发生率为16.67%(17/102),两组差异有统计学意义(χ =27.208,P<0.001)。结论:病灶黏膜下层纤维化、切除

             [Abstract] Objective:This study aims to explore a scoring system for predicting the risk of delayed bleeding after endoscopic
              submucosal dissection(ESD)for early gastric cancer(EGC). Methods:A retrospective analysis was performed on the data of 296
              patients with early gastric cancer(including high ⁃ grade intraepithelial neoplasia) who underwent ESD treatment in the
              Gastroenterology Department of the First Affiliated Hospital of Soochow University from February 2016 to November 2020. Multivariate
              logistic regression analysis was performed to investigate independent risk factors of delayed bleeding after ESD in EGC. Weighted
              points was proportionally assigned based on β regression coefficients value to construct the scoring system. According to the scores and
              the incidence of delayed bleeding,the receiver operating characteristic curve(ROC curve)was plotted,the area under the curve(AUC)
              was calculated,and risk stratification based on the scores was performed. Results:Multivariate analysis revealed that submucosal
