ABSTRACT Aim. To compare the effectiveness of surgical procedures (selective or nonselective shunt, devascularization, and combined shunt and devascularization) in preventing recurrent variceal bleeding and other complications in patients with portal hypertension.
Methods. A systematic literature search of the Medline and Cochrane Library databases was carried out, and a meta-analysis was conducted according to the guidelines of the Quality of Reporting Meta-Analyses (QUOROM) statement.
Results. There were a significantly higher reduction in rebleeding, yet a significantly more common encephalopathy (P = 0.05) in patients who underwent the shunt procedure compared with patients who had only a devascularization procedure. Further, there were no significant differences in rebleeding, late mortality, and encephalopathy between selective versus non-selective shunt. Next, the decrease of portal vein pressure, portal vein diameter, and free portal pressure in patients who underwent combined treatment with shunt and devascularization was more pronounced compared with patients who were treated with devascularization alone (P < 0.05).
Conclusions. This meta-analysis shows clinical advantages of combined shunt and devascularization over devascularization in the prevention of recurrent variceal bleeding and other complications in patients with portal hypertension.

    ABSTRACT: Most hepatocellular carcinomas (HCCs) are associated with cirrhosis. Portal hypertension (PHT) and esophageal variceal bleeding (EVB) can limit the patient's treatment options. Surgical therapy in such patients is challenging. We performed devascularization plus liver resection or radiofrequency ablation (RFA) to treat HCC patients with concomitant EVB resulting from PHT secondary to cirrhosis. Such combined operations have never been reported for the management of HCC patients with variceal esophageal bleeding. To evaluate two different treatment regimens for patients with HCC and EVB. We evaluated 35 BCLC stage 0/A patients with HCC and EVB who underwent either devascularization plus liver resection (Group A) or devascularization plus RFA (Group B). We reviewed the safety and outcomes of the two groups and assessed risk factors for patient survival and tumor recurrence. Significant factors for overall survival were surgical approach and Child-Pugh classification. Child-Pugh classification was the only independent risk factor for overall postoperative survival [hazard ratio (HR) 8.320, 95 % confidence interval (CI) 1.739-39.799, P = 0.008]. Age was the only independent risk factor for tumor recurrence (HR 4.025, 95 % CI 1.343-12.062, P = 0.013). RFA plus devascularization is the preferred treatment of HCC with EVB. RFA plus devascularization should be considered in Child-Pugh class A patients below 50 years of age.
