Review Meta Analysis Comparative Study
Arachnolysis or cerebrospinal fluid diversion for adult-onset syringomyelia? A Systematic review of the literature.
To identify surgical practice patterns in the literature for nonpediatric syringomyelia by systematic review and to determine the following: 1) What is the best clinical practice of cerebrospinal fluid (CSF) diversion to maximize clinical improvement or to achieve the lowest recurrence rate? 2) Does arachnolysis, rather than CSF diversion, lead to prolonged times to clinical recurrence? ⋯ With postinfectious and posttraumatic etiologies, arachnolysis was the only surgical treatment to have a statistically significant effect on decreasing recurrence rates. More prospective, randomized, controlled studies are required to reach a clear consensus.

Review Meta Analysis
Outcome predictors in the management of spinal myxopapillary ependymoma: an integrative survival analysis.
The results in earlier studies have described a variable association with age, extent of resection, and radiotherapy (RT) correlating with the survival of myxopapillary ependymomas. The aim of our study is to perform a survival analysis on patient data gathered from a comprehensive review of the literature and determine the influence of these factors on progression-free (PFS) and overall survival (OS). ⋯ Gross-total resection plays the most important role in improving PFS and OS. Older patients had better PFS; however, the influence of adjuvant RT was significant in younger age groups. A dose of >50 Gy improves the results, but a randomized controlled study is warranted to arrive at a definite conclusion.

Multicenter Study Comparative Study
A prospective, multi-institutional comparative effectiveness study of lumbar spine surgery in morbidly obese patients: does minimally invasive transforaminal lumbar interbody fusion result in superior outcomes?
Obese and morbidly obese patients undergoing lumbar spinal fusion surgery are a challenge to the operating surgeon. Minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF) and open-TLIF have been performed for many years with good results; however, functional outcomes after lumbar spine surgery in this subgroup of patients remain poorly understood. Furthermore, whether index MIS-TLIF or open-TLIF for the treatment of degenerative disc disease or spondylolisthesis in morbidly obese results in superior postoperative functional outcomes remains unknown. ⋯ MIS-TLIF is a safe and viable option for lumbar fusion in morbidly obese patients and, compared with open-TLIF, resulted in similar improvement in pain and functional disability. Postoperative complications rates between both cohorts were also not significantly divergent.

The optimal surgical procedure (direct, indirect, or combined anastomosis) for management of moyamoya disease is still debated. We evaluated the outcome of our broad area revascularization protocol, the Tokyo Daigaku (The University of Tokyo) (TODAI) protocol, analyzing the relative importance of direct, indirect, and combination revascularization strategies to identify the optimal surgical protocol. ⋯ The TODAI protocol provided efficient revascularization and yielded excellent results in preventing strokes in patients with moyamoya disease with very few complications. EMS had a main role in revascularization in each of the combined techniques.
