Abstract
INTRODUCTION: Splenectomy is associated with a life-long risk for overwhelming infections. The risk for early post-operative infectious complications following traumatic and elective splenectomy is, however, understudied. This investigation aimed to determine if splenectomy increases the risk for post-operative infections. METHODS: This was a retrospective review of prospectively collected data on patients admitted to the surgical intensive care unit (SICU) between 1/2011 and 7/2013 investigating the risk for infectious complications in patients undergoing a splenectomy compared with those undergoing any other abdominal surgery. RESULTS: During the 30-month study period, a total of 1884 patients were admitted to the SICU. Of those, 33 (2%) had a splenectomy and 493 (26%) had an abdominal surgery. The two groups were well balanced for age, APACHE IV score >20, and past medical history, including diabetes mellitus, cardiac history, renal failure or immunosuppression. Patients undergoing splenectomy were more likely to have sustained a traumatic injury (30% vs. 7%, p < 0.01). After adjustment, splenectomy was associated with increased risk for infectious complications (49% vs. 29%, Adjusted Odds Ratio (AOR) [95% CI]: 2.7 [1.3, 5.6], p = 0.01), including intra-abdominal abscess (9% vs. 3%, AOR [95% CI]: 4.3 [1.1, 16.2], p = 0.03). On a subgroup analysis, there were no differences between traumatic and elective splenectomy with regards to overall infectious complications (50% vs. 46%, p = 0.84), although, abdominal abscess developed only in those who had an elective splenectomy (0% vs. 12%, p = 0.55). CONCLUSION: Splenectomy increases the risk for post-operative infectious complications. Further studies identifying strategies to decrease the associated morbidity are necessary.
