Surgical Results of Endoscopic Discectomy for Lumbar Disc Herniation: Three-Year Follow-up

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.

Percutaneous Transforaminal Endoscopic Discectomy

Abstract Background . Lumbar disc herniation (LDH) is a common disease in spinal surgery which often causes acute radicular pain. However, LDH with buttock pain (BP) as the main clinical symptom is rare. Herein, we retrospectively evaluated the efficacy and safety of percutaneous transforaminal endoscopic discectomy (PTED) in the treatment of LDH with the buttock as the primary clinical symptom. Methods . Totally 12 patients have LDH (L4-5) with BP who underwent PTED from January 2019 to June 2020 were enrolled. All patients performed magnetic resonance imaging (MRI) and computed tomography (CT) preoperatively, 1 week postoperatively, and at follow-up. The pain relieve were evaluated by the Visual analog scale (VAS), the functional recovery was assessed by Oswestry disability index (ODI) and Roland-Morris questionnaire (RMQ). Parameters were evaluated preoperatively, immediately after surgery, 1 month, 3 months and 6 months after surgery, respectively. Moreover, the lumbar function was determined by modified MacNab criteria. Results . Pain relieve was found in 11 patients postoperatively. The VAS, ODI and RMQ scores were improved significantly at the latest follow up visit compared to preoperative (P < 0.05). One patient suffered from LDH recurrence one month after operation and received revision surgery, then achieved satisfied effect. Two patients experienced residual BP after operation and obtained good clinical outcomes by conservative treatment. No other surgical complications were found during follow up period. The average length of follow-up was 6.68 ± 0.67 months. Conclusion. PTED is a safe and efficacious method in treating LDH with BP.

Percutaneous Transforaminal Endoscopic Discectomy

Abstract Objective Percutaneous transforaminal endoscopic discectomy (PTED) is minimally invasive and has been widely used to treat patients with lumbar disc herniation (LDH) due to its safety and efficiency. However, due to the unique anatomy of the L5–S1 level, the PTED procedure is often difficult to perform in the region. ZESSYS, a targeted and quantificational foraminoplasty device, may help to overcome these anatomical limitations. In this study, we assessed the efficiency and the short-term effects of PTED with ZESSYS at the L5–S1 level. Methods Between January and August of 2018, fifty-six patients with lumbar disc herniation at the single level of L5–S1 and who underwent percutaneous transforaminal endoscopic discectomy were enrolled in this retrospective cohort study. They were segregated into the transforaminal endoscopic surgical system (TESSYS) group and the ZESSYS group. The puncture time, foraminoplasty time, decompression time, and fluoroscopy time were evaluated for operation efficiency. Clinical outcomes were assessed by the visual analog scale (VAS) score and Oswestry Disability Index (ODI) score. The MacNab criteria were used to evaluate patient subjective satisfaction at 12-month follow-up postoperatively. Results The average puncture time (5.29 ± 2.05 min), foraminoplasty time (12.82 ± 2.52 min), and fluoroscopy time (26.29 ± 5.96 s) were all significantly shorter in the ZESSYS group than in the TESSYS group (average puncture time 8.07 ± 3.13 min, p < 0.01; foraminoplasty time, 17.18 ± 2.92 min, p < 0.01; fluoroscopy time, 34.73 ± 6.86 s; p < 0.01). No significant differences were observed between the 2 groups in the decompression time (p = 0.057). The VAS score of low back pain and leg pain, as well as the ODI score, improved at all time points postoperatively compared with preoperative, in both the TESSYS group and the ZESSYS group (P < 0.05). There were no significant differences in the VAS score of low back pain, VAS score of leg pain, and ODI score between the TESSYS group and the ZESSYS group at the same time points (P > 0.05). According to the MacNab criteria, the excellent and good rate at 12-month follow-up postoperatively was 85.7% in the TESSYS group and 89.3% in the ZESSYS group (P > 0.05). Conclusion The targeted and quantificational foraminoplasty device named ZESSYS was more efficient in the puncture and foraminoplasty procedures, effectively protecting the exiting nerve and minimizing the level of radiation exposure. The device is efficient and safe for PTED in treating lumbar disc herniation at the L5–S1 level.

Abstract Background To compare the clinical outcomes of transforaminal lumbar interbody fusion (TLIF) and endoscopic discectomy in the treatment of postoperative adjacent segment degeneration in patients with lumbar disc herniation. Methods From 2014 to 2017, 87 patients who were diagnosed with single-level lumbar disc herniation (LDH) and received surgery of TLIF (group X, n = 43) or endoscopic discectomy (group F, n = 44) were retrospectively analyzed. X-ray, MRI, CT and clinical symptoms were recorded before operation and at the last follow-up. The neurological function was originally evaluated by the (JOA) score of the Japanese Orthopaedic Association. Radiological evaluation included the height of intervertebral space (HIS), intervertebral foramen height (FH), intervertebral foramen area (FA), lumbar lordosis (CA) and intervertebral disc degeneration pfirrmann score.Results There was no significant difference in average operation age, JOA improvement rate, reoperation rate and complications between the two groups. The average blood loss, average hospital stays and average operation time in group F were lower than those in group X. During the last follow-up, HIS, CA and FA decreased in both groups, and the changes in group X were more significant than those in group X (P < 0.05). There was no significant difference in postoperative FH between the two groups, but it decreased more in group X (P < 0.05).Conclusion Both TLIF and endoscopic surgery can achieve good results in the treatment of LDH, but the risk of lumbar adjacent segment degeneration after intervertebral foraminal surgery is lower.

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.

OBJECTIVEThe authors sought to investigate the efficiency of percutaneous endoscopic discectomy (PED) in adolescent patients with lumbar disc herniation (LDH), compare PED outcomes in adolescent patients with those in young adult LDH patients as controls, and discuss relevant technical notes.METHODSThis was a retrospective study involving 19 adolescent LDH patients (age > 13 and < 18 years, 20 discectomies) and 38 young adults (age < 40 years, 38 discectomies) who also had LDH and were matched to the adolescent group for sex and body mass index. The combined cohort included 51 male patients (89.5%) and 6 female patients (10.5%), with an average age of 26.7 years (range 14–39 years). The operated levels included L3–4 in 1 patient (1.7%), L4–5 in 22 patients (37.9%), and L5–S1 in 35 patients (60.4%). Two adolescents (10.5%) exhibited apophyseal ring separation and one (5.3%) had had previous PED. All patients underwent PED under local anesthesia. Outcomes were evaluated through a visual analog scale (VAS), the Japanese Orthopaedic Association (JOA) scoring system, and the modified MacNab grading system.RESULTSThe mean duration of follow-up was 41.7 months (range 36–65 months). The outcomes in adolescents were satisfactory and comparable with previously reported outcomes of microsurgical discectomy (MD) and conventional open discectomy (COD). The adolescent patients had a faster and better recovery course than the adult patients (p < 0.01). One adolescent patient (5.3%) exhibited recurrence and 2 adults (5.3%) experienced transient dysesthesia; the complication rates were comparable in the 2 age groups (p = 0.47). Prolonged duration of symptoms (p < 0.01) and disc degeneration (p = 0.01) were correlated with lower postoperative JOA values; patients with extrusions had higher postoperative JOA values than those with protrusions (p = 0.01).CONCLUSIONSPED may yield favorable results in the treatment of adolescent LDH in terms of short- to medium-term follow-up; restricted discectomy and a conservative rehabilitation program might be advisable. Further long-term studies are warranted to address this rare disease entity.

OBJECTIVEA prospective randomized controlled study was conducted to clarify whether percutaneous transforaminal endoscopic discectomy (PTED) results in better clinical outcomes and less surgical trauma than microendoscopic discectomy (MED).METHODSIn this single-center, open-label, randomized controlled trial, patients were included if they had persistent signs and symptoms of radiculopathy with corresponding imaging-confirmed lumbar disc herniation. Patients were randomly allocated to the PTED or the MED group by computer-generated randomization codes. The primary outcome was the Oswestry Disability Index (ODI) score 1 year after surgery. Secondary outcomes included scores of the Medical Outcomes Study 36-Item Short-Form Health Survey bodily pain and physical function scales, EuroQol Group’s EQ-5D , and the visual analog scales for back pain and leg pain. Data including duration of operation, in-bed time, length of hospital stay, surgical cost and total hospital cost, complications, and reoperations were recorded.RESULTSA total of 153 participants were randomly assigned to 2 treatment groups (PTED vs MED), and 89.5% (137 patients) completed 1 year of follow-up. Primary and secondary outcomes did not differ significantly between the treatment groups at each prespecified follow-up point (p > 0.05). For PTED, there was less postoperative improvement in ODI score in the median herniation subgroup at 1 week (p = 0.027), 3 months (p = 0.013), 6 months (p = 0.027), and 1 year (p = 0.028) compared with the paramedian subgroup. For MED, there was significantly less improvement in ODI score at 3 months (p = 0.008), 6 months (p = 0.028), and 1 year (p = 0.028) in the far-lateral herniation subgroup compared with the paramedian subgroup. The total complication rate over the course of 1 year was 13.75% in the PTED group and 16.44% in the MED group (p = 0.642). Five patients (6.25%) in the PTED group and 3 patients (4.11%) in the MED group suffered from residue/recurrence of herniation, for which reoperation was required.CONCLUSIONSOver the 1-year follow-up period, PTED did not show superior clinical outcomes and did not seem to be a safer procedure for patients with lumbar disc herniation compared with MED. PTED had inferior results for median disc herniation, whereas MED did not seem to be the best treatment option for far-lateral disc herniation.Clinical trial registration no.: NCT01997086 (clinicaltrials.gov).

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.
