With the aid of smaller skin incision, negligible blood loss and post-operative pain, Double Endoscopic Technique fits as the best strategy to manage degenerative lumbar spinal disorders.

With enhanced progressed experience and the accessibility of new technical tools, the surgical endoscopic implications for lumbar spinal pathologies have prompted from simple prolapsed disk to canal stenosis. The currently available endoscopes come in two distinct sizes; but, one is too small to obtain a fast bone decompression, and other is too bulky to use inside the spinal canal.

A Double Endoscopic Technique was developed to overcome these issues, using the different surgical technique. Seventeen participants with mixed single segmental lumbar canal stenosis (group A) were operated using this approach. All the participants of A group showed very good outcomes at VAS and ODI at a median of 13 months following the operation. The clinical outcomes of group A participants were compared with participants of another group (group B) who went through an operation in the same unit but employing standard MIS approach. Both groups exhibited similar factors like symptoms, number, age, and stenosis location. Both groups were compared for the quantity of postoperative painkillers employed during the first-week post-surgery, the blood loss during surgery, the period of in-hospital stay, and pre- and post-operative ODI and VAS values.

Based on these results, this method is effective and safe, producing an outcome similar to the standard MIS method. Moreover, it is less disruptive towards the associated anatomy, needs a smaller skin incision, blood loss is negligible, and cause less post-operative pain.

Therefore, the double endoscopic technique may ensure a quicker clinical recovery.
