Surgically treated patients (except changers) performed significantly better in all clinical outcome measures (p  less then  0.001) with a plateau at 12-month follow-up staying constant until the follow-up ended. Further, two thirds of patients in the surgical group had a relevant improvement in function, symptoms, and quality of life, compared to only about half of those in terms of symptoms and even less in terms of function and quality of life with non-surgical treatment. CONCLUSIONS Surgical treatment of DLSS results in more favorable clinical outcomes with a sustained effect over time, compared to non-surgical treatment. LEVEL OF EVIDENCE 3.STUDY DESIGN Retrospective observational study. OBJECTIVE The study objectives were to 1) determine radiographically which spinal malalignment parameters predominantly influence the risk of gastroesophageal reflux disease (GERD); 2) evaluate the outcome of GERD 2years after surgery for adult spinal deformity (ASD); and 3) clarify key factors that influence the improvement of postoperative GERD in ASD. SUMMARY OF BACKGROUND DATA Spinal deformity is reported to be involved in the pathology of GERD. Our previous study found that approximately 50% of patients treated surgically for ASD had GERD symptoms. However, the postoperative progress of GERD and the key factors that influence the improvement of postoperative GERD are largely unknown. METHODS Ninety-two patients with ASD treated with thoracolumbar corrective surgery and followed up for a minimum of 2 years were enrolled. All patients were asked to complete the Frequency Scale for Symptoms of GERD (FSSG) questionnaire preoperatively and at 1 and 2 years after surgery. GERD was diagnosed by FSSG score >8 points. Before, and at 1 and 2 years after surgery, full-length lateral radiographs were taken and radiographic parameters were obtained. RESULTS Patients were classified into two groups based on GERD symptoms, with 47 (51.1%) in the GERD+ group. Among parameters assessed, only thoracolumbar kyphosis (TLK) was significantly greater in the GERD+ group than in the GERD-group. The FSSG score improved significantly one year after surgery, but no significant difference was found between groups at two years. A significant correction loss of TLK was observed 2 years after surgery. There was a significant highly positive correlation between the FSSG score and TLK at 2 years after surgery. CONCLUSIONS GERD improved with correction of the spinal deformity but significant correction loss of the TLK even within the fusion presumably due to subsidence or proximal junctional kyphosis resulted in a cessation of that improvement over time. LEVEL OF EVIDENCE 3.STUDY DESIGN Retrospective cohort. OBJECTIVE To evaluate the effectiveness and safety of antifibrinolytic (AF) agents in reducing perioperative blood transfusion in pediatric patients undergoing spinal fusion. SUMMARY OF BACKGROUND DATA The potential for AF to decrease bleeding and reduce exposure to allogenic transfusions has led to widespread off-label use in a number of major pediatric surgical procedures. Recent reviews call for improving the body of evidence for their effectiveness and safety in pediatric spinal fusion. METHODS Children undergoing spinal fusion were identified in the American College of Surgeons National Surgical Quality Improvement Program Pediatric (NSQIP-P) 2016 and 2017 databases. Univariate analyses of patient and perioperative characteristics informed the creation of a propensity score model predicting treatment with AF, followed by 11 matching to allow comparison of allogenic red blood cell transfusion rates and secondary outcomes between treated and untreated patients. RESULTS Of 6626 total patients, 5434 (81%) received AF and 1533 (23%) received a blood transfusion. Analysis of data for 1192 propensity score-matched pairs revealed that treatment with AF was associated with a statistically non-significant 16% reduction in perioperative transfusion (OR 0.84, 95% confidence interval 0.68-1.05, p = 0.119) and a statistically significant 43% reduction in postoperative transfusion (OR 0.57, 95% confidence interval 0.39-0.81, p = 0.002). No differences in the incidences of postoperative seizure or thrombosis were observed, with overall rates of 7.5 and 22.5 events per 10,000 patients, respectively. CONCLUSIONS AF agents appear to reduce postoperative allogenic transfusion in children undergoing spinal fusion surgery. Adverse drug effects such as thromboembolic complications and seizure were extremely rare and warrant continued monitoring, though this is the largest study to date providing evidence for the safety profile of these drugs. LEVEL OF EVIDENCE 3.STUDY DESIGN Retrospective cohort study. L-685,458 OBJECTIVE To develop a comprehensive understanding of the prognostic value of laboratory markers on morbidity and mortality following epidural abscess. SUMMARY OF BACKGROUND DATA Spinal epidural abscess is a serious medical condition with high rates of morbidity. The value of laboratory data in forecasting morbidity and mortality after epidural abscess remains underexplored. METHODS We obtained clinical data on patients treated for epidural abscess at two academic centers from 2005-2017. Our primary outcome was the development of one or more complications within 90-days of presentation, with mortality a secondary measure. Primary predictors included serum albumin, serum creatinine, platelet-lymphocyte ratio and ambulatory status at presentation. We used multivariable logistic regression techniques to adjust for confounders. The most parsimonious set of variables influencing both complications and mortality were considered to be clinically significant. These were then eand laboratory values to prognosticate outcomes after treatment for epidural abscess. The results can be used in shared-decision making and counseling. LEVEL OF EVIDENCE 3.STUDY DESIGN A prospective, randomized, controlled study. OBJECTIVE To compare anterior controllable antidisplacement and fusion (ACAF) with laminoplasty in the treatment of multilevel ossification of the posterior longitudinal ligament (OPLL), and evaluate the efficacy and safety of this procedure. SUMMARY OF BACKGROUND DATA The optimal approach for the treatment of OPLL still remains controversial. Both anterior and posterior approaches have their advantages and disadvantages. METHODS Between September 2016 and April 2018, a total of 80 patients with multilevel OPLL were randomized in a 11 ratio to ACAF group and laminoplasty group. All patients were followed up at least one year. Clinical and radiological results were compared between ACAF group and laminoplasty group. RESULTS ACAF took a longer operation time. C5 palsy and axial pain occurred more commonly in laminoplasty group, whereas dysphagia and hoarseness appeared easily in ACAF group. At one-year follow-up, the final JOA score and RR were significant higher in ACAF group than those in laminoplasty group, when OR was not less than 60%, or K-line was negative.
