“…The decompression procedure will be performed bilaterally via unilateral access under constant saline irrigation and visual control [ 4 , 12 , 14 ], as shown in Fig 3B . Endoscopic bipolar cauterization will be used as necessary to achieve hemostasis [ 12 , 14 , 31 ]. After sufficient decompression, saline irrigation will be performed, and the endoscope will be withdrawn gradually [ 14 , 31 ].…”

“…A 10-15-mm longitudinal skin incision will be made 1 cm lateral to the spinous process under C-arm fluoroscopic guidance. This paramedian incision will allow the endoscope to be angled appropriately to reach the contralateral side [16,19,[28][29][30][31]. The working channel and endoscope will be introduced [16,29], and endoscopic laminectomy and bilateral decompression will be performed through a unilateral working channel [19,22,28,29,31] (Figs 3 and 4).…”

Evaluation of the efficacy and safety of conventional and interlaminar full-endoscopic decompressive laminectomy to treat lumbar spinal stenosis (ENDO-F trial): Protocol for a prospective, randomized, multicenter trial

et al. 2023

Lumbar spinal stenosis is a common spinal degenerative condition. Minimally invasive interlaminar full-endoscopic decompressive laminectomy provides greater patient satisfaction and faster recovery than open decompressive laminectomy. The aim of our randomized controlled trial will be to compare the safety and efficacy of interlaminar full-endoscopic laminectomy and open decompressive laminectomy. Our trial will include 120 participants (60 per group) who will undergo surgical treatment for lumbar spinal stenosis. The primary outcome will be the Oswestry Disability Index measured at 12 months postoperatively. Secondary patient-reported outcomes will include back and radicular leg pain measured via a visual analog scale; the Oswestry Disability Index; the Euro-QOL-5 Dimensions score measured at 2 weeks and at 3, 6, and 12 months postoperatively; and patient satisfaction. The functional measures will include time to return to daily activities postoperatively and walking distance/time. The surgical outcomes will include postoperative drainage, operation time, duration of hospital stay, postoperative creatine kinase (an indicator of muscle injury) level, and postoperative surgical scarring. Magnetic resonance and computed tomography images and simple radiographs will be obtained for all patients. The safety outcomes will include surgery-related complications and adverse effects. All evaluations will be performed by a single assessor at each participating hospital who will be blinded to group allocation. The evaluations will be conducted preoperatively and at 2 weeks and 3, 6, and 12 months postoperatively. The randomized, multicenter design of the trial, blinding, and justification of the sample size will reduce the risk of bias in our trial. The results of the trial will provide data regarding the use of interlaminar full-endoscopic laminectomy as an alternative to open decompressive laminectomy that results in similar surgical findings with less invasiveness. Trial registration: This trial is registered at cris.nih.go.kr. (KCT0006198; protocol version 1; 27 May 2021).
