The surgical portosystemic shunts (PSS) are a time-proven modality for treating portal hypertension. Recently, in the era of liver transplantation and the transjugular intrahepatic portosystemic shunts (TIPS), use of the PSS has declined.
This study was conducted to evaluate changes in practice, referral patterns, and short- and longterm outcomes of the use of the surgical PSS before and after the introduction of the Model for End-stage Liver Disease (MELD).
A retrospective analysis of 47 patients undergoing PSS between 1996 and 2011 in a single university hospital was conducted.
Subgroups of patients with cirrhosis (53%), Budd-Chiari syndrome (13%), portal vein thrombosis (PVT) (26%), and other pathologies (9%) differed significantly with respect to shunt type, Child-Pugh class, MELD score and perioperative mortality. Perioperative mortality at 60 days was 15%. Five-year survival was 68% (median: 70 months); 5-year shunt patency was 97%. Survival was best in patients with PVT and worst in those with Budd-Chiari syndrome compared to other subgroups. Patency was better in the subgroups of patients with cirrhosis and other pathologies compared with the PVT subgroup. Substantial changes in referral patterns coincided with the adoption of the MELD in 2002, with decreases in the incidence of cirrhosis and variceal bleeding, and increases in non-cirrhotics and hypercoagulopathy.
Although the spectrum of diseases benefiting from surgical PSS has changed, surgical shunts continue to constitute an important addition to the surgical armamentarium. Selected subgroups with variceal bleeding in well-compensated cirrhosis and PVT benefit from the excellent longterm patency offered by the surgical PSS.
外科门腔分流术(PSS)是治疗门静脉高压的一种经过时间验证的方法。近年来,在肝移植和经颈静脉肝内门体分流术(TIPS)时代,PSS 的应用有所减少。
本研究旨在评估在引入终末期肝病模型(MELD)前后,外科 PSS 的使用实践、转诊模式以及短期和长期结果的变化。
对 1996 年至 2011 年在一家大学医院接受 PSS 的 47 例患者进行回顾性分析。
肝硬化(53%)、布加综合征(13%)、门静脉血栓形成(PVT)(26%)和其他病理(9%)的患者亚组在分流类型、Child-Pugh 分级、MELD 评分和围手术期死亡率方面存在显著差异。术后 60 天的死亡率为 15%。5 年生存率为 68%(中位数:70 个月);5 年分流通畅率为 97%。与其他亚组相比,PVT 患者的生存率最好,而布加综合征患者的生存率最差。肝硬化和其他病变亚组的通畅率优于 PVT 亚组。转诊模式的重大变化与 2002 年 MELD 的采用相吻合,肝硬化和静脉曲张出血的发病率下降,非肝硬化和高凝状态的患者增加。
尽管受益于外科 PSS 的疾病谱发生了变化,但外科分流仍然是外科武器库的重要补充。在代偿良好的肝硬化和 PVT 患者中,伴有静脉曲张出血的选定亚组可从外科 PSS 提供的出色长期通畅率中获益。
