“…Kyung‐Chul Choi et al vaporized a down‐migrated L4–5 disc by epiduroscopic Ho:YAG laser application in 1 case and successfully removed the disc by the endoscopic method. Beyaz et al reported that they treated a patient with far‐lateral extruded disc herniation and a low foot with percutaneous discectomy and radiofrequency ablation. In this study, we treated patients with MSU 3AB herniated discs using a combined technique of percutaneous and epiduroscopic routes with a success rate of 82.9%.…”

Aim The aim of this study was to examine the effects of simultaneous epiduroscopic laser neural disc decompression (ELND) and percutaneous laser disc decompression (PLDD) applications using a holmium:yttrium‐aluminum‐garnet (Ho:YAG) laser in Michigan State University (MSU) classification 3AB herniated discs on VAS and Oswestry Disability Index (ODI) scores. Methods In this prospective observational study, ELND and PLDD procedures performed between January 2016 and December 2017 were examined. Preoperative, postoperative week 2, postoperative month 2, and postoperative month 6 ODI and VAS scores were obtained from patient files, and postoperative month 12 ODI and VAS scores were obtained from face‐to‐face interviews with patients and recorded. Results The data of 41 patients treated with simultaneous ELND and PLDD using a Ho:YAG laser were included in this study. Postoperative VAS scores of the patients were compared with preoperative values, and it was found that postoperative week 2, postoperative month 2, postoperative month 6, and postoperative month 12 VAS and ODI scores were significantly different compared to preoperative scores (P = 0.001; P < 0.01). 17.1% (n = 7) of the patients had a history of postoperative open surgery. Although dural puncture occurred in 7 patients (17%), only 1 patient had headache. Conclusion We believe that the new combined technique of ELND and PLDD using a Ho:YAG laser is a reliable method in patients with MSU classification 3AB herniated discs, with an acceptable success rate and a low complication rate within 12 months after treatment. We think that randomized controlled studies are required for this method to be included in treatment algorithms.

“…Finally, if difficulty was encountered attempting to locate the inferomedial genicular nerve, the Triggerflex RFA probe was utilized in a 360-degree manner to offset this limitation. The Triggerflex RFA probe allows easy implementation through working channels for navigational, targeted application of RF treatment on target tissues and has been utilized in several notable endoscopic procedures (11,17).…”

Endoscopic Pulsed Radiofrequency Ablation of Genicular Nerves for the Treatment of Chronic Knee Pain

Chronic knee pain is the second most common cause of chronic pain in the United States. Occasionally, patients become refractory to conventional treatments such as intraarticular cortisone injections and viscosupplementation. Patients who have exhausted these therapies or have a contraindication to the therapies may be candidates for diagnostic genicular nerve block and if successful, subsequent radiofrequency ablation (RFA). For patients who have undergone image-guided genicular nerve radiofrequency ablation with fluoroscopic or ultrasound guidance without success, an endoscopic approach can be used as an alternative modality with success. With direct visualization of the genicular nerves, the likelihood of success with an endoscopic approach increases as some patients can have varying anatomy of the genicular nerves for which cannot always be detected with fluoroscopy or ultrasound. The purpose of this study is to demonstrate the utilization of a direct endoscopic approach for genicular nerve RFA for patients with chronic knee pain that have failed to improve after image-guided genicular RFA with fluoroscopic or ultrasound guidance. Two patients who had underwent successful diagnostic genicular nerve blocks were assessed for pre-procedure and post-procedure visual analog scale (VAS) scores following endoscopic genicular nerve RFA after failure of the conventional image guided approach at 6 and 12 months. Both patients reported greater than 80% reduction in VAS score and improvement in function at 6 and 12 months Limitations of the current study is a limited number of patients, and lack of the use of a formal functional scale to demonstrate improvement. Ultimately, the conclusion was drawn that an endoscopically-guided genicular nerve RFA can be utilized successfully due to direct visualization of the genicular nerves when conventional approaches with Fluoroscopic/ultrasound guidance has failed to achieve analgesia and functional improvement.

“…Since patients with bony foraminal stenosis were excluded from the study, a routine foraminoplasty was not necessary. If bleeding occurred, a radiofrequency probe (Elliquence ® Baldwin, NY) was used for coagulation [ 46 ]. The endoscopic decompression procedure was directly visualized throughout the surgery.…”

(1) Background: Postoperative nerve root injury with dysesthesia is the most frequent sequela following lumbar endoscopic transforaminal discectomy. At times, it may be accompanied by transient and rarely by permanent motor weakness. The authors hypothesized that direct compression of the exiting nerve root and its dorsal root ganglion (DRG) by manipulating the working cannula or endoscopic instruments may play a role. (2) Objective: To assess whether intraoperative neurophysiological monitoring can help prevent nerve root injury by identifying neurophysiological events during the initial placement of the endoscopic working cannula and the directly visualized video endoscopic procedure. (3) Methods: The authors performed a retrospective chart review of 65 (35 female and 30 male) patients who underwent transforaminal endoscopic decompression for failed non-operative treatment of lumbar disc herniation from 2012 to 2020. The patients’ age ranged from 22 to 86 years, with an average of 51.75 years. Patients in the experimental group (32 patients) had intraoperative neurophysiological monitoring recordings using sensory evoked (SSEP), and transcranial motor evoked potentials (TCEP), those in the control group (32 patients) did not. The SSEP and TCMEP data were analyzed and correlated to the postoperative course, including dysesthesia and clinical outcomes using modified Macnab criteria, Oswestry disability index (ODI), visual analog scale (VAS) for leg and back pain. (4) Results: The surgical levels were L4/L5 in 44.6%, L5/S1 in 23.1%, and L3/L4 in 9.2%. Of the 65 patients, 56.9% (37/65) had surgery on the left, 36.9% (24/65) on the right, and the remaining 6.2% (4/65) underwent bilateral decompression. Postoperative dysesthesia occurred in 2 patients in the experimental and six patients in the control group. In the experimental neuromonitoring group, there was electrodiagnostic evidence of compression of the exiting nerve root’s DRG in 24 (72.7%) of the 32 patients after initial transforaminal placement of the working cannula. A 5% or more decrease and a 50% or more decrease in amplitude of SSEPs and TCEPs recordings of the exiting nerve root were resolved by repositioning the working cannula or by pausing the root manipulation until recovery to baseline, which typically occurred within an average of 1.15 min. In 15 of the 24 patients with such latency and amplitude changes, a foraminoplasty was performed before advancing the endoscopic working cannula via the transforaminal approach into the neuroforamen to avoid an impeding nerve root injury and postoperative dysesthesia. (5) Conclusion: Neuromonitoring enabled the intraoperative diagnosis of DRG compression during the initial transforaminal placement of the endoscopic working cannula. Future studies with more statistical power will have to investigate whether employing neuromonitoring to avoid intraoperative compression of the exiting nerve root is predictive of lower postoperative dysesthesia rates in patients undergoing videoendoscopic transforaminal discectomy.
