Objectives: Increased risk of perioperative complications in patients with type 2 diabetes mellitus (DM) has previously been noted with regard to a number of different operations. We sought to study the relative rates of postoperative complications after the surgical resection of an intracranial meningioma based on a pre-existing diagnosis of diabetes.
Methods: We conducted a retrospective cohort study on 259 patients who underwent a primary meningioma resection at our institution between 2001-2013. The medical record was reviewed to identify a pre-existing diagnosis of type 2 DM and any postoperative complications prior to discharge. The duration of postoperative hospital stay, intensive care unit (ICU) stay, perioperative changes in Karnofsky Performance Status (KPS) scores, and any postoperative emergency department (ED) presentation within 90 days of the operation were also recorded for each patient. Multivariable logistic regression models were built to determine the impact of a history of diabetes on postoperative complications and post-discharge presentation to the ED. Multivariable linear regression models were designed to assess the predictors of lengthier hospitalization and ICU stays in addition to differential postoperative changes in KPS scores.
Results: Forty-one (16%) patients had diagnoses of type 2 DM prior to clinical presentation. In multivariate analyses, patients with a pre-existing history of diabetes had a higher risk of postoperative complications, postoperative ED presentation, and deterioration in functional status in addition to lengthier durations of hospitalization and ICU stay (p<0.001, p=0.008, p<0.001, p=0.007, p<0.001).
Conclusions: Patients with pre-existing diagnoses of type 2 DM have a significantly increased risk of immediate postoperative complications following the resection of an intracranial meningioma. Type 2 DM also predicts increased lengths of postoperative hospital stay, decreased postoperative performance status, and increased risk of postoperative ED presentation.
