文摘目的评估内镜序贯经颈静脉肝内门体分流术(TIPS)治疗肝硬化急性食管胃静脉曲张破裂出血(EGVB)的安全性及有效性。方法将2019年9月—2021年3月接受内镜序贯TIPS治疗的肝硬化急性EGVB 31例作为内镜序贯TIPS组,将接受单纯内镜序贯治疗的46例作为内镜序贯组。观察内镜序贯TIPS组门静脉压力梯度变化情况,比较2组静脉曲张改善程度及肝功能变化,术后1、3、6、12个月再出血率及肝性脑病发生率,随访结束后分析2组生存情况。结果内镜序贯TIPS组术后门静脉压力梯度低于术前(P<0.01)。内镜序贯TIPS组术后丙氨酸转氨酶(ALT)、天冬氨酸转氨酶(AST)术后1个月高于其他时点(P<0.05),术后3个月开始下降;内镜序贯TIPS组术后血清胆红素升高,术后3个月直接胆红素(DBIL)和间接胆红素(IBIL)升至高峰,术后6个月逐渐下降(P<0.05)。内镜序贯组术后3、7 d ALT、AST较术前降低,ALB较术前升高(P<0.05);术后1个月总胆红素(TBIL)水平低于术前(P<0.05);术后7 d及术后1、3个月DBIL低于术前(P<0.05)。2组术后静脉曲张根除率比较差异无统计学意义(P>0.05)。内镜序贯TIPS组术后6、12个月再出血率低于内镜序贯组(P<0.01);2组术后肝性脑病发生率及术后1年生存率比较差异均无统计学意义(P>0.05)。结论TIPS可降低门静脉压力,静脉曲张根除率与内镜序贯治疗相当,但可有效降低再出血率,而并不降低生存率且不增加肝性脑病发生率。内镜序贯TIPS治疗肝硬化EVGB安全有效。
