    Patients with a history of esophageal varices bleeding require evaluation of liver function and portal venous flow before decompression surgery. This prevents re-bleeding by guiding appropriate shunt surgery selection based on liver biopsy and angiography results.

    Area of Science:

    • Gastroenterology
    • Hepatology
    • Surgical Gastroenterology

    Background:

    • Esophageal varices pose a significant risk of recurrent hemorrhage in patients with liver disease.
    • Effective management of these patients requires thorough pre-operative evaluation to prevent further bleeding events.

    Purpose of the Study:

    • To outline the essential pre-operative evaluations for patients undergoing elective variceal decompression.
    • To guide the selection of appropriate surgical shunts based on patient-specific factors.

    Main Methods:

    • Evaluation includes hepatic function, neurologic status, nutritional status, and ascites assessment.
    • Key diagnostic procedures are liver biopsy to assess necroinflammatory activity and visceral angiography to determine portal venous flow direction (hepatopetal or hepatofugal).

    Main Results:

    • Liver biopsy findings guide surgical timing: shunt surgery is indicated for minimal necroinflammatory activity, while delayed surgery is recommended for moderate to severe activity.
    • Visceral angiography results dictate shunt type: selective distal splenorenal shunt for hepatopetal flow and total shunts (e.g., portacaval, mesocaval) for hepatofugal flow.

    Conclusions:

    • Pre-operative evaluation is critical for preventing recurrent variceal hemorrhage after decompression surgery.
    • Tailoring surgical intervention based on liver biopsy and visceral angiography findings optimizes patient outcomes.
