Patients with medium- or largesized varices can be treated for primary prophylaxis of variceal bleeding using two strategies: non-selective beta-blockers(NSBBs) or endoscopic variceal ligation(EVL). Both treatments are equally effective. Patients with acute variceal bleeding are critically ill patients. The available data suggest that vasoactive drugs, combined with endoscopic therapy and antibiotics, are the best treatment strategy with EVL being the endoscopic procedure of choice. In cases of uncontrolled bleeding, transjugular intrahepatic portosystemic shunt(TIPS) with polytetrafluoroethylene(PTFE)-covered stents are recommended. Approximately 60% of the patients experience rebleeding, with a mortality rate of 30%. Secondary prophylaxis should start on day six following the initial bleeding episode. The combination of NSBBs and EVL is the recommended management, whereas TIPS with PTFE-covered stents are the preferred option in patients who fail endoscopic and pharmacologic treatment. Apart from injection sclerotherapy and EVL, other endoscopic procedures, including tissue adhesives, endoloops, endoscopic clipping and argon plasma coagulation, have been used in the management of esophageal varices. However, their efficacy and safety, compared to standard endoscopic treatment, remain to be further elucidated. There are safety issues accompanying endoscopic techniques with aspiration pneumonia occurring at a rate of approximately 2.5%. In conclusion, future research is needed to improve treatment strategies, including novel endoscopic techniques with better efficacy, lower cost, and fewer adverse events.展开更多

Many years ago, surgical procedures such as esophageal transection or distal splenorenal shunting were the only treatments for EVs. In the 1970s, interventional radiology procedures such as transportal obliteration, left gastric artery embolization, and partial splenic artery embolization were introduced, improving the survival of patients with bleeding EVs. In the 1980s, endoscopic treatment, endoscopic injection sclerotherapy (EIS), and endoscopic variceal ligation (EVL), further contributed to improved survival. We combined IVR with endoscopic treatment or EIS with EVL. Most patients with EVs treated endoscopically required follow- up treatment for recurrent varices. Proper management of recurrent EVs can significantly improve patients’ quality of life. Recently, we have performed EVL at 2-mo (bimonthly) intervals for the management of EVs. Longer intervals between treatment sessions resulted in a higher rate of total eradication and lower rates of recurrence and additional treatment.展开更多

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。
文摘目的 比较内镜下套扎治疗与内镜下组织胶注射用于肝硬化胃静脉曲张出血二级预防的疗效及安全性。方法 选择2017年1月至2019年12月因肝硬化胃静脉曲张出血入住复旦大学附属中山医院,行食管胃曲张静脉内镜下套扎治疗的患者(套扎组),另选择同期行内镜下组织胶注射治疗的患者(组织胶组),通过倾向性评分匹配,两组分别纳入59例。采用单因素与多因素Cox比例风险回归模型分析食管胃静脉曲张再出血影响因素。绘制Kaplan-Meier曲线,比较两组患者再出血及生存情况。结果 套扎组与组织胶组患者食管胃静脉曲张根除率差异无统计学意义(83.05%vs 79.66%,P=0.778);套扎组根除静脉曲张所须中位内镜治疗次数(2 vs 3次,P=0.017)及平均组织胶用量明显少于组织胶组(0.70 mL vs 2.67 mL,P<0.001)。多因素Cox回归分析显示,门体分流是食管胃静脉曲张再出血的危险因素(HR=3.14,95%CI 1.02~9.68,P=0.046),内镜下套扎是预防再出血的保护因素(HR=0.25,95%CI 0.08~0.71,P=0.010)。相较于内镜下组织胶注射,内镜下套扎不增加患者2年食管胃静脉曲张再出血风险(18.69%vs 36.29%,P=0.067)与死亡风险(1.69%vs 3.39%,P=1.000)。相较于内镜下组织胶注射,经内镜下套扎治疗后,GOV1型患者食管胃静脉曲张再出血风险较低(0 vs 40.27%,P=0.012),GOV2型患者再出血风险(13.27%vs 34.16%,P=0.056)呈降低趋势。结论 内镜下套扎治疗对食管胃静脉曲张的根除率较高,且并不增加再出血、死亡等事件风险,可作为胃静脉曲张出血患者的二级预防手段。
