To ascertain neurosurgical practices in the surgical management of one-level lumbar discectomies in the Canadian adult population.
One page questionnaire faxed to each Neurosurgeon in Canada with questions relating to their practice in the management of this common neurosurgical procedure. All data analyzed using Chi-square statistics.
112 completed surveys were returned hence, giving a 64% response rate with the respondents being predominantly adult neurosurgeons. Of the respondents, 88% perform lumbar discectomy in adults. Only 15% of respondents had a Spine Fellowship. For preoperative imaging, 44% use BOTH CT and MRI whereas 28% use only MRI and 15% use only CT. Prior to initial skin incision, 57% use a localization X-ray image. Preoperative antibiotics are prescribed by 92% of respondents. Majority of respondents (60%) use a pre-incision local anesthetic, whereas only a minority (44%) of respondents employ pre-closure intramuscular injection. With respect to magnification, 70% use microscope, 19% loupes, and 8% neither. Only 12% use minimally invasive tubular retractors. 68% remove “as much disc as possible”, while 31% remove “ONLY herniated part”. In the case of dural tears, 77% of respondents use fibrin glue (Tisseel®). Prior to skin closure, majority of neurosurgeons do NOT use a fat graft (72%), whereas 61% of respondents use epidural steroids. With respect to discharge from the hospital, 58% are discharged on the next day, 18% on the same day, and 23% in two days. Return to work is not recommended until at least six weeks post-op (96%). Most neurosurgeons (93%) would not operate on an individual with a chief complaint of low back pain.
Our survey has identified variations in practice patterns amongst Canadian Neurosurgeons with respect to performing one-level lumbar discectomies. This survey is expected to form a basis for the design of a randomized controlled trial in the evaluation of the best management approach for this common neurosurgical procedure.
Neurenteric cysts are congenital cysts of the central nervous system that are believed to be of endodermal origin. In this report we present the unique case of a supratentorial neurenteric cyst that is contained entirely within the brain parenchyma.
Apatient presented with an intraparenchymal cystic lesion that was subsequently identified as a neurenteric cyst. This lesion is reviewed in light of the available literature.
A 35-year-old female presented with a one year history of progressive headaches and seizure-like episodes. Her examination revealed no deficits. Magnetic resonance imaging showed a 4 cm x 4 cm x 4 cm cystic lesion within the parenchyma of the right frontal lobe. A right frontal craniotomy and complete excision of the cystic lesion was performed. Pathologic examination confirmed that it was a neurenteric cyst. Postoperatively the patient's symptoms improved.
Review of the literature revealed this to be the first case of a surgically excised, pathologically confirmed supratentorial neurenteric cyst, contained entirely within the brain parenchyma.
