摘要 目的探究圈套器辅助内镜黏膜下剥离术(ESD)治疗胃肠道息肉后迟发性出血(DPPB)的风险因素,并建立预测DPPB风险的列线图模型。方法选择2018年5月至2020年11月在我院行圈套器辅助ESD治疗胃肠道息肉的226例患者,其中DPPB患者10例(DPPB组)、未出血患者216例(未出血组)。分别比较两组患者的临床、内镜资料与DPPB的相关性。采用单因素分析筛选出术后DPPB的影响因素、多因素Logisitic回归分析筛选影响DPPB的危险因素,将筛选出的独立危险因素构建列线图预测模型。结果单因素、多因素Logisitic回归分析显示,高血压、息肉部位、息肉直径、息肉形态、术中出血是影响DPPB的独立危险因素(P<0.05)。列线图模型预测DPPB风险的C-index值为0.791,区分度良好;校准曲线显示预测DPPB发生风险与实际DPPB发生风险平均绝对误差为0.014,准确度良好。结论高血压、息肉部位、息肉直径、息肉形态、术中出血是DPPB的独立危险因素,基于此建立的预测DPPB风险的列线图模型具有良好的区分度与准确度,临床中应考虑对高风险人群进行针对性防控,以降低DPPB的发生。
