Variceal bleeding should be managed by sclerotherapy for control of acute bleeding, and as the initial method in preventing recurrence. Surgery is required for the 30-40% who fail sclerotherapy. The surgical choices are selective variceal decompression, total portal systemic shunt, devascularization procedures, liver transplantation. Distal splenorenal shunt (DSRS) combines good control (greater than 90%) and maintenance of hepatic function. Survival after DSRS is significantly better in nonalcoholic, 75% at 5 years, compared to alcoholic cirrhotics, 45% at 5 years: this difference is associated with improved maintenance of portal flow in the former. Loss of portal flow in 60% of alcoholics has led to modification of DSRS with total disconnection of the splenic vein from the pancreas, resulting in improved portal flow maintenance. Patients with bleeding secondary to portal vein thrombosis and schistosomiasis are excellent candidates for DSRS. Total shunts will stop bleeding, and may be required emergently for uncontrolled hemorrhage. Portacaval H-graft is easily performed, but loss of portal flow accelerates liver failure. Devascularization procedures have a 20-40% rebleeding rate, but do not accelerate liver failure. Liver transplantation is increasingly indicated for patients with end-stage liver disease and variceal bleeding. However, it is the degree of hepatic failure, rather than the variceal bleeding per se, which dictates the need for this therapy. Optimal patient care requires that a center should be able to offer all such therapies.
静脉曲张破裂出血的治疗应采用硬化疗法来控制急性出血,并作为预防复发的初始方法。对于30%-40%硬化疗法失败的患者需要进行手术。手术选择包括选择性静脉曲张减压、全门体分流术、去血管化手术、肝移植。远端脾肾分流术(DSRS)既能很好地控制出血(超过90%),又能维持肝功能。与酒精性肝硬化患者5年生存率45%相比,非酒精性肝硬化患者DSRS术后5年生存率显著更高,为75%:这种差异与前者门静脉血流维持改善有关。60%的酒精性肝硬化患者门静脉血流丧失,促使对DSRS进行改良,将脾静脉与胰腺完全离断,从而改善门静脉血流维持。门静脉血栓形成和血吸虫病继发出血的患者是DSRS的理想候选者。全分流术可止血,对于无法控制的出血可能需要紧急进行。门腔静脉H形移植术操作简便,但门静脉血流丧失会加速肝功能衰竭。去血管化手术的再出血率为20%-40%,但不会加速肝功能衰竭。对于终末期肝病合并静脉曲张破裂出血的患者,肝移植的应用越来越多。然而,决定是否需要这种治疗的是肝功能衰竭的程度,而非静脉曲张破裂出血本身。最佳的患者护理要求一个中心应能够提供所有这些治疗方法。
