Non-operative management and immune function after splenic injury

Area of Science:

• Trauma Surgery
• Surgical Oncology
• Immunology

Background:

• Spleen preservation after trauma is debated, balancing immune function against infection risk.
• Spleen-preserving surgery and non-operative management evolved due to postsplenectomy infection risks.
• Angiographic embolization is a recent strategy to enhance conservative splenic injury management.

Purpose of the Study:

• To review the historical and current approaches to splenic injury management.
• To evaluate methods for preserving splenic immune function post-trauma.
• To assess the efficacy of non-operative management and angiographic embolization.

Main Methods:

• A comprehensive literature review was conducted.
• The review focused on treatments for splenic injury over the past century.
• Emphasis was placed on maintaining splenic immune function.

Main Results:

• Non-operative management shows high success rates in stable patients (adults and children).
• Angiographic embolization increases non-operative management success to approximately 95%.
• Splenic function post-embolization is still under investigation but appears preserved in some studies.

Conclusions:

• Non-operative management is the primary strategy for preserving splenic immune function.
• Immunization may not be necessary after angiographic embolization for splenic injury.
• Further research is needed to identify splenic function tests and balance bleeding risk with spleen preservation.
