Septic sequelae after splenectomy for trauma in adults

Area of Science:

• Trauma Surgery
• Infectious Diseases
• Sepsis Research

Background:

• Splenectomy is a common procedure for trauma patients.
• The spleen plays a crucial role in immune function.
• Post-splenectomy complications, particularly sepsis, are a concern.

Purpose of the Study:

• To evaluate the incidence of systemic sepsis and mortality in trauma patients following splenectomy.
• To compare septic complication rates between splenectomized trauma patients and non-splenectomized trauma patients.
• To assess long-term outcomes, including severe bacterial and viral infections, after splenectomy in trauma survivors.

Main Methods:

• Retrospective analysis of 619 trauma patients who underwent splenectomy.
• Comparison of septic morbidity and mortality rates with a control group of 2,368 trauma patients.
• Long-term follow-up of 242 patients for a mean of 4.4 years.

Main Results:

• Systemic sepsis developed in 22.7% of splenectomized patients surviving >10 days postoperatively.
• Intra-abdominal abscess was the most frequent septic focus.
• Septic morbidity and mortality were significantly higher (p<0.01) in splenectomized patients compared to controls.
• Patients under 15 years old had no septic complications or deaths.
• Long-term follow-up revealed severe bacterial infections in 2.5% and increased viral infections in 11.5%.

Conclusions:

• Splenectomy in trauma patients is associated with a significantly increased risk of sepsis and mortality.
• The severity of trauma correlates with the incidence of postoperative septic complications.
• Preserving the spleen in trauma patients should be prioritized to mitigate severe infectious risks.
