RESUMO

Introduction Tandem spinal stenosis (TSS) refers to the narrowing of the spinal canal at two distinct anatomic areas. Symptoms can present due to either cervical myelopathy or lumbar stenosis. Consequently, determining the symptomatic anatomical levels requiring surgery can pose a challenge. We sought to identify the surgical approach associated with better patient-reported outcomes. Materials and Methods The Information Management System was queried using the International Classification of Diseases Ninth and Tenth Edition codes to identify patients who underwent simultaneous or staged decompression surgery for TSS between 2011 and 2020. Patient records were reviewed to collect data on age, sex, comorbidities, surgical approach, modified Japanese Orthopedic Association (mJOA) score, and complications. The mJOA is a validated composite assessment used to quantify postoperative neurological status. Multivariable regression models were utilized to identify factors associated with better postoperative neurological recovery. Results Among 42 patients included in the analytical cohort, 33 (78.6%) underwent simultaneous cervical and lumbar decompression, while 9 (21.4%) underwent staged decompression (cervical followed by lumbar). The patient's age, sex, comorbid conditions, and American Society of Anesthesiologists level were similar between the two groups. Furthermore, simultaneous decompression was associated with higher blood loss (676.97 vs. 584.44 mL) and an increased need for transfusion (259.09 vs. 111.11 mL) compared with staged decompression. Moreover, patients who underwent simultaneous decompression experienced a higher number of postoperative complications (10 vs. 1; p = 0.024). Notably, postoperative mJOA scores improved in both groups; however, the improvement was more pronounced in the staged group (mJOA score: 15.16% [ ± 2.18] vs. 16.56% [ ± 1.59]). On follow-up visits, patients who underwent staged decompression showed better recovery rates (mJOA score: 78.20% [ ± 24.45] vs. 59.75% [ ± 25.05]). Conclusion The patient's clinical history and examination findings should be the main determinants of surgical decision-making. Our study showed a slightly higher postoperative mJOA score and a recovery rate with fewer complications in staged decompression of TSS.

RESUMO

Introduction: The effect of chronic steroid therapy on postoperative outcomes after craniotomy for tumor resection remains understudied. Research question: This study aimed to fill this gap and to identify risk factors of postoperative morbidity and mortality among patients on chronic steroid use undergoing craniotomy for tumor resection. Materials and methods: Data from the American College of Surgeons National Surgical Quality Improvement Program were used. Patients who underwent craniotomy for tumor resection between 2011 and 2019 were included. Perioperative characteristics and complications were compared among patients with and without chronic steroid therapy, defined as steroid use for at least 10 days. Multivariable regression analyses were conducted to assess the impact of steroid therapy on postoperative outcomes. Subgroup analyses involving patients on steroid therapy were conducted to explore risk factors of postoperative morbidity and mortality. Results: Of 27,037 patients, 16.2% were on steroid therapy. On regression analyses, steroid use was significantly associated with any postoperative complication, infectious complication, urinary tract infection, septic shock, wound dehiscence, pneumonia, non-infectious, pulmonary, and thromboembolic complications, cardiac arrest, blood transfusion, unplanned reoperation, readmission, and mortality. On subgroup analysis, risk factors for postoperative morbidity and mortality among patients on steroid therapy included older age, higher American Society of Anesthesiology physical status, functional dependence, pulmonary and cardiovascular comorbidities, anemia, dirty/infected wounds, prolonged operative time, disseminated cancer, and a diagnosis of meningioma. Discussion and conclusion: Preoperative brain tumor patients on steroids for 10 or more days are at a relatively high risk of postoperative complications. We recommend a judicious use of steroids in brain tumor patients, both in terms of dosage and duration of treatment.
