Summary

Splenectomy significantly increases lifelong risk of overwhelming infection, even with vaccination. Surgeons now favor nonoperative management for splenic injuries due to these severe post-splenectomy complications and mortality risks.

Area of Science:

  • Surgical outcomes and infectious disease risk.
  • Clinical management of splenic trauma.

Background:

  • Splenectomy, or spleen removal, is associated with a substantially increased lifelong risk of overwhelming infection.
  • This heightened risk of post-splenectomy septic syndrome persists despite pneumococcal vaccination.

Purpose of the Study:

  • To review the significant risks and complications associated with splenectomy.
  • To highlight the evolving surgical approaches to splenic trauma management.

Main Methods:

  • Review of medical literature and clinical data concerning splenectomy outcomes.
  • Analysis of infection rates, mortality, and postoperative complications in asplenic patients.

Main Results:

  • Splenectomy patients face a lifelong risk of overwhelming sepsis, with reported incidence rates of 2.5-13.5% (estimated true incidence 5-10%).
  • Increased frequency of adverse events, including death, atelectasis, pancreatitis, pulmonary embolism, and bleeding, are common post-splenectomy complications.
  • Infections, particularly pulmonary and abdominal sepsis, are the leading cause of mortality.

Conclusions:

  • The high risks associated with splenectomy have led to a shift towards nonoperative management for stable splenic injuries.
  • Surgical options like splenorrhaphy are now preferred when laparotomy is necessary.
  • For essential splenectomies, vaccination and prompt medical attention for fever are crucial; autotransplantation and prophylactic antibiotics require further study.
