Brief summary
To evaluate a new endoscopic technique for lumbar spinal canal decompression.
Detailed description
104 consecutive patients suffering of neurogenic claudication were included in the study. Patients were operated using the irrigation endoscopic decompression technique. Mean Follow up was 28 months Primary outcome measures were assessed using the Oswestry Disability Index \[19\] and the modified Macnab Criteria All statistical calculations were done using computer programs SPSS (Statistical Package for the Social Science; SPSS Inc., Chicago, IL, USA) version 15 for Microsoft Windows
Interventions
PROCEDUREIrrigation Endoscopic Decompressive Laminotomy
2 portals 0.5cm were used one for the endoscope and the other for instruments. For every additional level one portal is added. The endoscope and instruments are directly placed over the surface of lamina without any dissection and saline under pump pressure is used to open a potential working space. Unilateral laminotomy/laminectomy is performed according to the severity of stenosis, followed by bilateral decompression beneath the midline structures.
