BACKGROUND: Splenectomy is indicated for selected patients with lymphoid neoplasms. We examined surgical morbidity and mortality in this high-risk patient population using a contemporary national cohort, with attention to hospitalization status before surgery. MATERIALS AND METHODS: The American College of Surgeons National Surgical Quality Improvement Program database (2005-2013) was queried for patients with lymphoid malignancies undergoing splenectomy. Stepwise statistical analyses were performed to identify factors associated with increased risk of death and serious morbidity (DSM). A risk scoring system was developed to predict DSM. RESULTS: In 456 patients, morbidity rate was 24.1%, and mortality rate was 2.4%. Albumin <3 g/dL (odds ratio [OR] = 2.6, P = 0.005), hematocrit <30% (OR = 2.8, P < 0.0001), and a history of chronic obstructive pulmonary disease (OR = 3.4 P = 0.009) were independent predictors of DSM. Rates of DSM were stratified by these risk factors (RFs): 13.5% (0 RF), 34.4% (1 RF), and 58.5% (2-3 RF), P < 0.0001. Patients admitted before surgery (IP) were more likely to have RF compared with those undergoing surgery on the day of admission (SDS); 74.6 versus 26.4%, P < 0.001. Morbidity (39.7% versus 18.2%, P < 0.0001) and mortality (7.1% versus 0.6%, P < 0.0001) were significantly increased in the IP group. CONCLUSIONS: Splenectomy for lymphoid neoplasm in hospitalized patients is associated with substantial morbidity and mortality. Risk stratification in this group may aid in perioperative management to mitigate DSM.
