    Splenectomy alone in cirrhotic patients with esophageal varices risks bleeding. Combining splenectomy with a prophylactic shunt significantly prevents variceal bleeding and lowers portal pressure, though careful patient selection is crucial.

    Area of Science:

    • Gastroenterology
    • Hepatology
    • Surgical Oncology

    Background:

    • Splenectomy for splenic conditions in cirrhotic patients with esophageal varices presents a dilemma regarding prophylactic shunting.
    • Splenectomy alone does not reduce portal pressure or improve esophageal varices, leading to a 36% risk of variceal bleeding.
    • Post-splenectomy splenoportal thrombosis can preclude future therapeutic shunts in survivors of initial bleeding.

    Purpose of the Study:

    • To evaluate the efficacy and safety of combining splenectomy with a prophylactic shunt in cirrhotic patients with esophageal varices.
    • To assess the impact on variceal bleeding, portal pressure, and patient survival.

    Main Methods:

    • A cohort of 24 patients underwent splenectomy with a prophylactic shunt.
    • Patient selection, diet, and medical management were carefully controlled.

  • Outcomes including bleeding episodes, portal pressure, encephalopathy, mortality, and survival rates were monitored.

    • Main Results:

    • The combined procedure resulted in a 16% mortality rate and 0% incidence of variceal bleeding.
    • Splenectomy effectively lowered portal pressure in the treated patients.
    • Hepatic encephalopathy occurred in 30% of cases, but severe complications were avoided through careful management.

    Conclusions:

    • Combining splenectomy with a prophylactic shunt is a viable strategy to prevent variceal bleeding in select cirrhotic patients.
    • Careful patient selection and management are essential to mitigate risks like encephalopathy.
    • The 5-year survival rate was 60%, supporting the procedure's benefit in specific high-risk cases.
