Objective: The paradigm of surgical therapy for spinal disease especially for lumbar disc herniation has gradually shifted from traditional open surgeries to minimally invasive spinal surgeries. Endoscopic discectomy has been performed widely using various devices and techniques. In this study, we present our experience of endoscopic discectomy using a unique device with separate side viewing channel. Methods: 26 patients of lumbar disc herniation treated between March 2015 to April 2018 using the unique conical working tube with separate side-viewing endoscopic channel have been retrospectively analysed. Their preoperative and postoperative Oswestry Disability Index (ODI) and Macnab scores were used to evaluate the outcome with a mean follow up of 37.04 months. Results: There were 18 males and 08 females with age ranging from 19-72 years (mean-38.4 years). The follow up ranged from 25 months to 60 months with a mean of 37.04 months. The mean preoperative ODI score was 72.4 which decreased to a mean of 7.6 and the outcome evaluated by Macnab criteria was 65.3% excellent, 19.2 % good, 11.5% fair, 3.8% poor. 1 patient underwent a second surgery. None of the patients had to change their occupation postoperatively. Complications occurred were dural tear in 1 patient and transient foot paresis in 1 which improved spontaneously. Conclusion: Endoscopic discectomy using conical working tube is a safe and effective technique for lumbar disc prolapse. The long term results are comparable to conventional techniques.

Abstract Background: Although numerous studies have shown good clinical results of percutaneous endoscopic lumbar discectomy (PELD) for hospitalized patients with lumbar disc herniation (LDH), there are few articles that report on the day surgery patients undergoing PELD.Methods: Atotal of 267 patients with LDH received PELD during day surgery were followed up for at least 3 years. Relevant data and clinical outcomeswere recorded and assessed. Meanwhile, we compared the clinical effects between patients treated by PELD during day surgery and microendoscopic discectomy (MED) for contemporaneous hospitalized patients with LDH (116 patients).Results: Patients treated by PELD had lower blood loss (10.8 ± 4.1 mL, 71.3 ± 23.3 mL,respectively; P < 0.001) and shorter hospital stay ( 22.7 ± 4.2 hours, 48.1 ± 22.6 hours, respectively; P < 0.001 ) compared with patients treated by MED. The visual analogue scale (VAS) for leg and back pain (VAS-L and VAS-B, respectively) and Oswestry disability index (ODI) decreased significantly after PELD than those before the operation at 3 years postoperative, and the postoperative VAS-B in PELD group was significantly decreased from the MED group ( P = 0.001). The complications rate was 9.4% (25/267) in the PELD group and 12.1% (14/116) in the MED group, without significant difference ( P = 0.471). The 1-year postoperative recurrence rate in PELD group ( 5.2%, 14/267) was much higher than that in MED group ( 0.9%, 1/116) ( P = 0.042). The postoperative lumbar lordosis(LL)(34.0 ±10.3 ), and sacral slope(SS) (27.5 ± 5.6) in PELD group improved significantly compared with the values in MED group (26.9 ± 9.8, 23.6 ± 6.8, respectively; all P < 0.001). The disc-height ratio at 3-year follow-up was ( 85.7 ± 6.4) % of the preoperative disc height in PELD group while ( 81.9 ± 7.0) % in MED group,with significant height loss in MED group ( P = 0.014).Conclusions: Day surgery for LDH undergoing PELD has favorable long-term outcomes.

OBJECTIVE Throughout the last decades, full-endoscopic techniques to treat lumbar disc herniation (LDH) have gained popularity in clinical practice. To date, however, no Class I evidence on the efficacy of percutaneous transforaminal endoscopic discectomy (PTED) has been published, and studies describing its safety and short- and long-term efficacy are scarce. In this study the authors aimed to evaluate the clinical outcomes and safety in patients undergoing PTED for LDH. METHODS Patients who underwent PTED for LDH between January 2009 and December 2012 were prospectively followed. The primary outcomes were the visual analog scale (VAS) score for leg pain and the score on the Quebec Back Pain Disability Scale (QBPDS). Secondary outcomes were the perceived experience with the local anesthesia used and satisfaction with the results after 1 year using Likert-type scales. The pretreatment means were compared with the means obtained 6 and 52 weeks after surgery using paired t-tests. RESULTS A total of 166 patients underwent surgery for a total of 167 LDHs. The mean duration of surgery (± SD) was 51.0 ± 9.0 minutes. The 1-year follow-up rate was 95.2%. The mean reported scores on the VAS and QBPDS were 82.5 ± 17.3 mm and 60.0 ± 18.4 at baseline, respectively. Six weeks after surgery, the scores on the VAS and QBPDS were significantly reduced to 28.8 ± 24.5 mm and 26.7 ± 20.6, respectively (p < 0.001). After 52 weeks of follow-up, the scores were further reduced compared with baseline scores (p < 0.001) to 19.6 ± 23.5 mm on the VAS and 20.2 ± 18.1 on the QBPDS. A total of 4 complications were observed, namely 1 dural tear, 1 deficit of ankle dorsiflexion, and 2 cases of transient paresis in the foot due to the use of local anesthetics. CONCLUSIONS PTED appears to be a safe and effective intervention for LDH and has similar clinical outcomes compared to conventional open microdiscectomy. High-quality randomized controlled trials are required to study the efficacy and cost-effectiveness of PTED.

Abstract Background The area which located at the medial pedicle, posterior vertebral body and ventral hemilamina is defined as the hidden zone. Surgical management of hidden zone lumbar disc herniation (HZLDH) is technically challenging due to its difficult surgical exposure. The conventional interlaminar approach harbors the potential risk of post-surgical instability, while other approaches consist of complicated procedures with a steep learning curve and prolonged operation time. Objective To introduce microscopic extra-laminar sequestrectomy (MELS) technique for treatment of hidden zone lumbar disc herniation and present clinical outcomes. Methods Between Jan 2016 to Jan 2018, twenty one patients (13 males) with HZLDH were enrolled in this study. All patients underwent MELS (19 patients underwent sequestrectomy only, 2 patients underwent an additional inferior discectomy). The nerve root and fragment were visually exposed using MELS. The operation duration, blood loss, intra- and postoperative complications, and recurrences were recorded. The Visual Analog Scale (VAS), Oswestry Disability Index (ODI), and the modified MacNab criteria were used to evaluate clinical outcomes. Postoperative stability was evaluated both radiologically and clinically. Results The mean follow-up period was 20.95 ± 2.09 (18–24) months. The mean operation time was 32.43 ± 7.19 min and the mean blood loss was 25.52 ± 5.37 ml. All patients showed complete neurological symptom relief after surgery. The VAS and ODI score were significantly improved at the final follow-up compared to those before operation (7.88 ± 0.70 vs 0.10 ± 0.30, 59.24 ± 10.83 vs 11.29 ± 3.59, respectively, p < 0.05). Seventeen patients (81%) obtained an “excellent” outcome and the remaining four (19%) patients obtained a “good” outcome based the MacNab criteria. One patient suffered reherniation at the same level one year after the initial surgery and underwent a transforaminal endoscopic discectomy. No major complications and postoperative instability were observed. Conclusions Our observation suggest that MELS is safe and effective in the management of HZLDH. Due to its relative simplicity, it comprises a flat surgical learning curve and shorter operation duration, and overall results in reduced disturbance to lumbar stability.

Background. Among the surgical methods for lumbar disc herniation, open lumbar microdiscectomy is considered the gold standard. Recently, percutaneous endoscopic lumbar discectomy is also commonly performed for lumbar disc herniation for its various strong points. Objectives. The present study aims to examine whether percutaneous endoscopic lumbar discectomy and open lumbar microdiscectomy show better results as surgical treatments for lumbar disc herniation in the Korean population. Methods. In the present meta-analysis, papers on Korean patients who underwent open lumbar microdiscectomy and percutaneous endoscopic lumbar discectomy were searched, both of which are surgical methods to treat lumbar disc herniation. The papers from 1973, when percutaneous endoscopic lumbar discectomy was first introduced, to March 2018 were searched at the databases of MEDLINE, EMBASE, PubMed, and Cochrane Library. Results. Seven papers with 1254 patients were selected. A comparison study revealed that percutaneous endoscopic lumbar discectomy had significantly better results than open lumbar microdiscectomy in the visual analogue pain scale at the final follow-up (leg: mean difference [MD]=-0.35; 95% confidence interval [CI]=-0.61, -0.09; p=0.009; back: MD=-0.79; 95% confidence interval [CI]=-1.42, -0.17; p=0.01), Oswestry Disability Index (MD=-2.12; 95% CI=-4.25, 0.01; p=0.05), operation time (MD=-23.06; 95% CI=-32.42, -13.70; p<0.00001), and hospital stay (MD=-4.64; 95% CI=-6.37, -2.90; p<0.00001). There were no statistical differences in the MacNab classification (odds ratio [OR]=1.02; 95% CI=0.71, 1.49; p=0.90), complication rate (OR=0.72; 95% CI=0.20, 2.62; p=0.62), recurrence rate (OR=0.83; 95% CI=0.50, 1.38; p=0.47), and reoperation rate (OR=1.45; 95% CI=0.89, 2.35; p=0.13). Limitations. All 7 papers used for the meta-analysis were non-RCTs. Some differences (type of surgery (primary or revisional), treatment options before the operation, follow-up period, etc.) existed depending on the selected paper, and the sample size was small as well. Conclusion. While percutaneous endoscopic lumbar discectomy showed better results than open lumbar microdiscectomy in some items, open lumbar microdiscectomy still showed good clinical results, and it is therefore reckoned that a randomized controlled trial with a large sample size would be required in the future to compare these two surgical methods.

OBJECTIVELumbar disc herniation (LDH) in the pediatric population is rare and exhibits unique characteristics compared with adult LDH. There are limited data regarding the safety and efficacy of minimally invasive surgery (MIS) using tubular retractors in pediatric patients with LDH. Here, the outcomes of MIS tubular microdiscectomy for the treatment of pediatric LDH are evaluated.METHODSTwelve consecutive pediatric patients with LDH were treated with MIS tubular microdiscectomy at the authors’ institution between July 2011 and October 2015. Data were gathered from retrospective chart review and from mail or electronic questionnaires. The Macnab criteria and the Oswestry Disability Index (ODI) were used for outcome measurements.RESULTSThe mean age at surgery was 17 ± 1.6 years (range 13–19 years). Seven patients were female (58%). Prior to surgical intervention, 100% of patients underwent conservative treatment, and 50% had epidural steroid injections. Preoperative low-back and leg pain, positive straight leg raise, and myotomal leg weakness were noted in 100%, 83%, and 67% of patients, respectively. The median duration of symptoms prior to surgery was 9 months (range 1–36 months). The LDH level was L5–S1 in 75% of patients and L4–5 in 25%. The mean ± SD operative time was 90 ± 21 minutes, the estimated blood loss was ≤ 25 ml in 92% of patients (maximum 50 ml), and no intraoperative or postoperative complications were noted at 30 days. The median hospital length of stay was 1 day (range 0–3 days). The median follow-up duration was 2.2 years (range 0–5.8 years). One patient experienced reherniation at 18 months after the initial operation and required a second same-level MIS tubular microdiscectomy to achieve resolution of symptoms. Of the 11 patients seen for follow-up, 10 patients (91%) reported excellent or good satisfaction according to the Macnab criteria at the last follow-up. Only 1 patient reported a fair level of satisfaction by using the same criteria. Seven patients completed an ODI evaluation at the last follow-up. For these 7 patients, the mean ODI low-back pain score was 19.7% (SEM 2.8%).CONCLUSIONSTo the authors’ knowledge, this is the longest outcomes study and the largest series of pediatric patients with LDH who were treated with MIS microdiscectomy using tubular retractors. These data suggest that MIS tubular microdiscectomy is safe and efficacious for pediatric LDH. Larger prospective cohort studies with longer follow-up are needed to better evaluate the long-term efficacy of MIS tubular microdiscectomy versus other open and MIS techniques for the treatment of pediatric LDH.

Abstract Background: Percutaneous Transforaminal Endoscopic Discectomy is used increasingly in patients with Lumbar Disc Herniation. There is little knowledge on the related factors including SLR test influencing the operation. Therefore, we designed this prospective study to explore the relevant factors influencing postoperative effect of PTED surgery.Methods: Consecutive patients with LDH who came to our hospital from August 2015 to September 2016 and received PTED surgery. 4 kinds of scales including VAS (lumbar/leg), ODI and JOA were measured and reassessed at 1 day, 3 months, 6 months, 12months and 36 months after the PTED to assess their surgical outcomes. Results: All the patients had successful surgery. ODI and VAS (lumbar/leg) decreased in all patients and groups. And there was a statistically significant difference in each postoperative follow-up compared with that before surgery in every visit. In addition, the increase of JOA in postoperation was statistically significant compared with that before surgery. And, there is statistically significant difference between the three subpopulations (patients with SLR Positive (0°-30°), SLR Positive (31°-60°) and SLR Negative (61°-) in the changes of the scores of VAS(leg), ODI and JOA. However, there is no statistically significant difference between the three subpopulations (patients with SLR Positive (0°-30°), SLR Positive (31°-60°) and SLR Negative (61°--RRB- in the changes of the score of VAS(lumbar). Conclusions: PTED showed great effect on treating patients with lumbar disc herniation. And the main scale score such as VAS(leg). ODI and JOA showed that there is a statistically significant difference between the three subpopulations treated by PTED. Patients with SLR negative may get greater benefit from PTED.
