Definitive therapy for variceal hemorrhage has evolved during the past half century. Only completely decompressing shunts (nonselective shunts) were available before 1967. Additional options now include selective shunts, devascularization procedures, endoscopic sclerotherapy, pharmacotherapy, and hepatic transplantation. Although drug treatment is experimental at the present time, the remaining therapeutic options are applicable to various subgroups of patients and in certain clinical settings. At the University of Nebraska, patients with variceal bleeding are first grouped based on their candidacy for transplantation. Transplantation candidates with advanced (Child's class C) or symptomatic liver disease undergo transplantation as soon as possible. Future transplantation candidates with stable, asymptomatic liver disease undergo either long-term sclerotherapy or a distal splenorenal shunt if sclerotherapy fails or if they have poor access to tertiary medical care. These patients are carefully monitored so that they can undergo transplantation before they become high-operative risks. Patients who are not candidates for transplantation receive chronic variceal sclerotherapy as initial therapy so long as shunt surgery is readily available if sclerotherapy fails. When surgery is indicated, the distal splenorenal shunt is preferred to nonselective shunts because several controlled and uncontrolled series have demonstrated a lower frequency of encephalopathy after selective variceal decompression.
在过去的半个世纪里,静脉曲张出血的确定性治疗方法不断演变。1967年以前,只有完全减压分流术(非选择性分流术)可用。现在的其他选择包括选择性分流术、去血管化手术、内镜硬化疗法、药物治疗和肝移植。虽然目前药物治疗仍处于试验阶段,但其余的治疗选择适用于不同亚组的患者以及某些临床情况。在内布拉斯加大学,静脉曲张出血患者首先根据其移植候选资格进行分组。患有晚期(Child C级)或有症状肝病的移植候选者尽快接受移植。未来有稳定、无症状肝病的移植候选者,如果硬化疗法失败或难以获得三级医疗服务,则接受长期硬化疗法或远端脾肾分流术。对这些患者进行密切监测,以便他们在成为高手术风险患者之前能够接受移植。不适合移植的患者接受慢性静脉曲张硬化疗法作为初始治疗,前提是如果硬化疗法失败,分流手术随时可用。当需要进行手术时,首选远端脾肾分流术而非非选择性分流术,因为多个对照和非对照系列研究表明,选择性静脉曲张减压后脑病的发生率较低。
