“…One implication of these findings may be that in cases of smaller tumor volumes (less than 3 cm 3 ) hemilaminectomy is a viable option and provides adequate visibility and access for safe and complete resection, whereas larger tumors may require a laminectomy for safe and complete resection. Lee et al noted similar results in a series of 26 patients who underwent successful resection of spinal schwannomas less than 16 mm in axial diameter regardless of foraminal or sagittal extension, utilizing hemilaminectomies [1]. Additionally, tumor histopathology and location are important considerations when selecting the appropriate approach.…”

“…Recent trends towards MIS techniques and cost-effective utilization of limited hospital resources have introduced questions regarding which surgical approaches should be used to access spinal pathologies. Moreover, multiple studies have confirmed the potential for reduced estimated blood loss, and lower length of hospital stays with MIS techniques [1,5,8,[14][15][16][17]20]. These favorable results are typically attributed to the minimal disruption of the posterior tension band with little mention of the effects of the extent of bony resection.…”

“…Intradural spinal cord tumors, although frequently of benign histopathologic origins, can lead to compressive myelopathy and radiculopathy due to rigid architecture of the spinal canal and neural foramina [1]. When neurological deficits are present, including myelopathy and radiculopathy, surgery is considered to prevent further neurological decline.…”

“…Historically, the posterior laminectomy has been the favored approach for approaching intradural spinal tumors [1,2]. In 1829, Alban Smith described the first successful posterior laminectomy to access the spinal canal for decompression of the spinal cord in the setting of trauma [3].…”

Traditionally, laminectomy has been the preferred surgical approach for the resection of intradural spinal tumors. Recent trends towards minimally invasive techniques have generated interest in hemilaminectomy as an effective alternative surgical approach to resect spinal tumors. However, it remains unclear if the potential benefits of hemilaminectomies, used in other routine spinal procedures, apply to intradural spinal tumors. This report presents a sixyear single institutional analysis of open resection of intradural tumors using laminectomies as compared to hemilaminectomies. Methods A single institution, multisurgeon, retrospective review of 52 patients undergoing resection of intradural spinal tumors over a six-year period was performed. Estimated blood loss, operative time, post-operative complications, length of stay, and post-operative clinical spinal instability were analyzed and compared between the two surgical techniques.

“…Practicing neurosurgeons will encounter patients with intraspinal tumors. Therefore, they need to be aware of their clinical presentation and diagnostic evaluation, the tumor types, management options, and frequency of treatment-related complications [3]. Treatment for most patients with primary intraspinal tumors includes inpatient hospital stay with surgery for biopsy or resection [4].…”

Significance of the Study• The Caspar distraction device has advantages of smaller wound, less bleeding, fewer postoperative reactions, shorter hospitalization period, and faster recovery. • Exposure of the tumor was not as adequate as that in the standard laminectomy group, especially in the management of ependymoma. • For minimally invasive surgery, preoperative diagnosis is very important, and schwannoma or fibroma with length < 6 cm is the absolute indication for Caspar surgery. AbstractObjective: This study aims to investigate the clinical efficacy of minimally invasive microsurgical resection of intraspinal tumors with the aid of Caspar retractors. Materials and Methods: A total of 125 intraspinal tumor patients with lesions smaller than 6 cm, who were treated at the Neurosurgery Department of our hospital from March 2010 to March 2016, were retrospectively analyzed. Among these, 73 patients underwent microsurgical resection of intraspinal tumors with the aid of Caspar retractors, while 52 patients underwent conventional laminectomy for resection of intraspinal tumors. Relevant indicators between both groups of patients were compared, including length of surgical inci-sion, duration of surgery, postoperative drainage volume, time to first out-of-bed activity after surgery, postoperative hospitalization period, visual analog score (VAS) score, and Japanese Orthopedic Association (JOA) score, at 1 month after surgery. Results: Compared with the conventional laminectomy group, patients who underwent microsurgical resection with the aid of Caspar retractors had better outcomes in terms of length of surgical incision, postoperative drainage volume, time to first out-of-bed activity after surgery, postoperative hospitalization period, and VAS scores (p < 0.05). However, JOA scores at 1 month after surgery did not have any significant differences (p > 0.05). Conclusions:The microsurgical resection of intraspinal tumors with the aid of Caspar retractors has advantages of small trauma, less bleeding, and faster recovery. It is a safe and efficacious method for treating small intraspinal tumors.
