    Summary
    This summary is machine-generated.

    Total splenectomy, or spleen removal, significantly increases the risk of overwhelming sepsis and disseminated intravascular coagulation, even decades later. Preserving some splenic tissue is recommended when spleen removal is unavoidable.

    Area of Science:

    • Immunology
    • Surgical Pathology
    • Hematology

    Background:

    • The spleen plays a crucial role in immune surveillance and blood filtration.
    • Splenectomy, the surgical removal of the spleen, is associated with significant long-term health risks.

    Purpose of the Study:

    • To summarize current knowledge on splenic function and the complications of total splenectomy.
    • To evaluate the indications for splenectomy and discuss methods for splenic tissue preservation.

    Main Methods:

    • Review of existing literature on splenic function and post-splenectomy complications.
    • Analysis of clinical outcomes and risks associated with splenectomy.
    • Discussion of surgical techniques for spleen-preserving procedures.

    Main Results:

    • The primary complication of splenectomy is overwhelming postsplenectomy infection (OPSI), a rapidly fatal sepsis.
    • OPSI can occur at any time after surgery, including up to 25 years post-operation.
    • Disseminated intravascular coagulation (DIC) is a frequent and severe consequence of OPSI.

    Conclusions:

    • There are limited legitimate indications for total splenectomy.
    • Careful patient selection and consideration of risks are essential before splenectomy.
    • Whenever possible, preserving some splenic tissue should be prioritized to mitigate risks.
