ObjectivePosterior fossa tumor surgery in children poses a significant morbidity and mortality. Large multi-institutional datasets characterizing the epidemiology and morbidity of children undergoing posterior fossa tumor surgery are lacking. The objective of this study is to describe the epidemiology and short term surgical outcomes of children presenting with cerebellar tumors.Patients and methodsA retrospective review of the Kids Inpatient Database (KID) for all hospital discharges in 2012 with a diagnosis of cerebellar tumor (ICD-9 diagnosis code 191.6) was performed and filtered with the ICD-9 procedure code 01.59 (other excision or destruction of lesion or tissue of brain). All children in this cohort were compared with all other children discharged without cerebellar tumors recorded in the database.ResultsA total of 461 (1.7/10,000 discharges) children with a diagnosis of cerebellar tumor who had surgical resection of their tumor were discharged during 2012. Compared with the control group, children undergoing cerebellar tumor excision had an increased length of hospital stay (8 vs. 2 days, p < 0.001), discharge to skilled nursing home facilities/home health care (12% vs. 4.6%, p < 0.001), increased hospital charges ($125,747 vs. $14,018, p < 0.001), and mortality (0.87% vs. 0.3%, p = 0.028). Hydrocephalus was treated via external ventriculostomy (EVD) (31%, n = 143) and/or shunt (17%, n = 78), and patients who required an EVD were more likely to receive a shunt (56% vs. 26%, p < 0.001). Mechanical ventilation (7.8%) and ultimately tracheostomy (1.5%) was necessary in few children following cerebellar tumor excision.ConclusionsAs expected, surgical treatment of cerebellar tumors in children may pose significant morbidity. Our exploratory study identifies these patients as a potential high-risk cohort in the United States that may require intensive airway management, treatment of hydrocephalus and long-term nursing support.
