    Summary

    Modified distal splenorenal shunts effectively treated esophageal varices in 18 patients. This surgical approach eliminated variceal bleeding post-operation with minimal complications, offering a safe and viable treatment for portal hypertension.

    Area of Science:

    • Gastroenterology and Hepatology
    • Vascular Surgery
    • Interventional Radiology

    Background:

    • Esophageal and esophagogastric varices are serious complications of portal hypertension.
    • Traditional treatments carry significant risks and recurrence rates.
    • Distal splenorenal shunt (DSSS) is a surgical option for managing varices.

    Purpose of the Study:

    • To evaluate the efficacy and safety of two modified distal splenorenal shunt techniques.
    • To assess the long-term patency and clinical outcomes in patients with varices.

    Main Methods:

    • Eighteen patients with varices underwent modified DSSS using expanded polytetrafluoroethylene interposition.
    • Bilateral gastric venous decompression was achieved by preserving the splenic vein in select cases.

  • Porta-azygos disconnection was confirmed intraoperatively via splenoportography.

    • Main Results:

    • All shunts remained patent 14-56 days post-surgery, confirmed angiographically.
    • Varices disappeared or significantly improved in all patients.
    • No variceal bleeding occurred postoperatively; morbidity and mortality were minimal.

    Conclusions:

    • Modified distal splenorenal shunt is a safe and effective procedure for managing esophageal varices.
    • This technique offers excellent long-term patency and prevents rebleeding.
    • It represents a valuable therapeutic option for patients with portal hypertension.
