Double Endoscopic Technique with negligible blood loss, minimum post-operative pain and smaller skin incision promise a faster clinical recovery during lumbar canal stenosis as compared to the standard MIS approach, according to a study published in Journal of Neurological Sciences. The two already available 6.3 mm and10 mm endoscopes has limitations like one is too small to obtain a quick bone decompression, and the other is too bulky to use inside the spinal canal.

Therefore, Investigators of Neurosurgical Unit, Azienda Universitaria Integrata, Italy developed and introduced novel surgical techniques and named Double Endoscopic Technique. A total of seventeen patients suffering from mixed (prolapsed disk and ligament-bone hypertrophy) single segmental lumbar canal stenosis were enrolled for the collection of clinical information. All these participants exhibited a favourable result with an improvement of the ODI and VAS.

The outcomes involved pre- and post-operative ODI and VAS scores, the length of in-hospital stay, the blood loss during surgery, and the number of postoperative painkillers used during the first-week post-surgery. The clinical results of this group were compared with the group of participants who went through the standard MIS technique. Both groups were similar with respect to the age, stenosis location and symptoms. The outcomes, study limitations comprising small numbers and short follow-up showed that the method is effective and safe, submitting an outcome similar to the standard MIS program. Moreover, Double Endoscopic Technique less disruptive with respect to the associated anatomy. With all findings, the new approach provides excellent results to manage the condition.
