Abstract
INTRODUCTION Endoscopic spine surgery is increasingly being used, and techniques, platforms, and applications are rapidly evolving. Despite substantial enthusiasm surrounding these techniques, there is a dearth of longer term patient-reported clinical outcomes. Within the United States in particular, there are yet to be reported large cohort studies with a notable follow-up. We sought to characterize the clinical outcomes of patients undergoing microendoscopic decompression (MED) for lumbar disk herniations. METHODS The records of patients with symptomatic lumbar disk herniations who underwent MED from May 2018 to February 2021 within a single practice were reviewed. Paired outcomes scores were evaluated using Patient-Reported Outcomes Measurement Information System parameters. Basic perioperative data including length of stay, estimated blood loss, mean opioid use, complication rate, and rate of revision were tabulated. Paired sample Student t-tests and paired Wilcoxon sign tests were used to compare normally distributed and nonparametric data, respectively. RESULTS Thirty-five patients with complete paired patient-reported outcome measures data and a minimum 6-month follow-up were included; 65.7% of the patients were male with a mean age of 47.1 years (SE 1.8). The mean follow-up was 590.6 days (SE 47.7). In total, 34 of the 35 patients (97.1%) were discharged on the day of their procedure. The estimated blood loss was <25 mL for each procedure. The mean opioid use after extubation and before discharge was 10.4 morphine milligram equivalents. At the 2-week follow-up, there were notable improvements in pain metrics and global health components. At the final follow-up, nearly all parameters showed notable improvement that exceeded minimally clinical important difference values. For most parameters, preoperative values outside of the "normal" range were within normal limits on postoperative testing. DISCUSSION MED resulted in sustained notable improvement in patient-reported outcome measures that exceeded minimally clinical important difference values at the average follow-up approximating 2 years. These findings substantiate the utility of this technique and additional investment in endoscopic spine technology. DATA AVAILABILITY Not publicly available; available upon request.

Abstract
STUDY DESIGN Systematic review. OBJECTIVE The authors aimed to systematically compare the effectiveness and safety of endoscopic discectomy (ED) with non-endoscopic discectomy (NED) for treatment of symptomatic lumbar disc herniation (LDH). METHODS A systematic search was performed on PubMed, EMBASE, the Cochrane Library and China National Knowledge Infrastructure for randomized controlled trial from inception until August 13, 2020. Trials which investigated multiple operative approaches on lumbar disc herniation were identified without language restrictions. RESULTS In total, 25 trials involving 2258 patients with symptomatic LDH were included. Twenty trials performed the comparison between ED and NED. Five trials performed the comparison between percutaneous endoscopic transforaminal discectomy (PETD) and percutaneous endoscopic interlaminar discectomy (PEID). The operative time of micro-endoscopic discectomy (MED) was longer than open discectomy (OD). The length of hospital stay of percutaneous endoscopic lumbar discectomy (PELD) was shorter than fenestration discectomy (FD). Significant differences in intraoperative blood loss volumes were found between PELD with FD and MED with OD. The complication rate of PELD was lower than FD (PELD: 4.3%; FD: 14.6%) and the complication rate of full-endoscopic discectomy (FE) was lower than microscopic discectomy (MD) (FE: 13.4%; MD: 32.1%). CONCLUSIONS PELD and FE have the advantage of limiting intraoperative damages. ED and NED can be both considered sufficient to achieve good clinical outcomes. PETD and PEID are able to achieve similar results but the learning curve of PETD was steeper. More independent high-quality RCTs with sufficiently large sample sizes performing cost-effectiveness analyzes are needed.

J Neurosurg Spine 2022; 36:704-712.

Abstract
OBJECTIVE Lumbar discectomy is a frequently performed procedure to treat sciatica caused by lumbar disc herniation. Multiple surgical techniques are available, and the popularity of minimally invasive surgical techniques is increasing worldwide. Clinical outcomes between these techniques may not show any substantial differences. As lumbar discectomy is an elective procedure, patients' own preferences play an important role in determining the procedure they will undergo. The aims of the current study were to determine the relative preference weights patients apply to various attributes of lumbar discectomy, determine if patient preferences change after surgery, identify preference heterogeneity for choosing surgery for sciatica, and calculate patient willingness to pay for other attributes. METHODS A discrete choice experiment (DCE) was conducted among patients with sciatica caused by lumbar disc herniation. A questionnaire was administered to patients before they underwent surgery and to an independent sample of patients who had already undergone surgery. The DCE required patients to choose between two surgical techniques or to opt out from 12 choice sets with alternating characteristic levels: waiting time for surgery, out-of-pocket costs, size of the scar, need of general anesthesia, need for hospitalization, effect on leg pain, and duration of the recovery period. RESULTS A total of 287 patients were included in the DCE analysis. All attributes, except scar size, had a significant influence on the overall preferences of patients. The effect on leg pain was the most important characteristic in the decision for a surgical procedure (by 44.8%). The potential out-of-pocket costs for the procedure (28.8%), the wait time (12.8%), need for general anesthesia (7.5%), need for hospitalization (4.3%), and the recovery period (1.8%) followed. Preferences were independent of the scores on patient-reported outcome measures and baseline characteristics. Three latent classes could be identified with specific preference patterns. Willingness-to-pay was the highest for effectiveness on leg pain, with patients willing to pay €3133 for a treatment that has a 90% effectiveness instead of 70%. CONCLUSIONS Effect on leg pain is the most important factor for patients in deciding to undergo surgery for sciatica. Not all proposed advantages of minimally invasive spine surgery (e.g., size of the scar, no need of general anesthesia) are necessarily perceived as advantages by patients. Spine surgeons should propose surgical techniques for sciatica, not only based on own ability and proposed eligibility, but also based on patient preferences as is part of shared decision making.

[PMID: 35489597 DOI: 10.1016/j.wneu.2022.04.056] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/17/2022] [Revised: 04/12/2022] [Accepted: 04/13/2022] [Indexed: 11/28/2022]
Abstract
BACKGROUND Percutaneous endoscopic lumbar discectomy (PELD) has become a favorable surgical approach for lumbar radiculopathy caused by intervertebral disc herniation. Studies have revealed patients with type II Modic change may suffer from unrelieved low back pain and higher lumbar disc herniation (LDH) recurrence after herniated nucleus pulposus removal. Therefore, in this study, we aim to evaluate how PELD performed in management of LDH patients with type II Modic change. METHODS We collected 267 single-level LDH cases aged 20-50 yearswho underwent PELD from December 2016 to December 2019. The mean follow-up time was 26.3 months (range: 12-48 months). The visual analog scale (VAS), Oswestry Disability Index (ODI), and MacNab scores, as well as the recurrence rate, were analyzed pre- and post-surgery, as well as at the time points of 3 months, 12 months, and the final follow-up time after surgery. The clinical outcomes in LDH patients with or without type II Modic change who underwent PELD were thoroughly analyzed. RESULTS Within the 267 LDH patients enrolled, 145 cases present Modic signals, among which 3 are type I and 142 are type II. The VAS and ODI scores of the patients in the 2 groups at different follow-up times were significantly lower than those before surgery. The excellent and good MacNab scores in the control group and Modic type II change group were 87.0% and 82.1%, respectively. However, with the extension of follow-up time, the VAS and ODI scores, as well as the recurrence rate, were found to be higher in the type II Modic change group when compared with those in the non-Modic change group. CONCLUSIONS PELD performed well in management of LDH patients. However, we need to pay more attention to the continuous low back pain and the recurrence possibility in the cases with type II Modic change. In these cases, longer brace support or other interventions could be applied.

J Orthop Surg Res 2022; 17:187. [PMID: 35346274 PMCID: PMC8962468 DOI: 10.1186/s13018-022-03052-1] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/04/2021] [Accepted: 03/02/2022] [Indexed: 11/23/2022] Open
Abstract
Background Advances in minimally invasive surgery have expanded the indications for interlaminar full-endoscopic discectomy. Although the clinical outcomes for this approach may be equivalent to those of conventional microscopic discectomy, the supporting evidence is still based on small, single-center, prospective, and retrospective studies. Therefore, a multicenter randomized controlled trial is warranted. Methods This will be a prospective, multicenter, randomized controlled trial comparing the efficacy and safety of interlaminar full-endoscopic discectomy to those of conventional microscopic discectomy. The trial will enroll 100 participants with a lumbar disc herniation, 50 in each group. The primary outcome will be the Oswestry Disability Index (ODI) score at 12 months post-surgery. Secondary outcomes will be back and leg pain (visual analog scale); the ODI; the EuroQol-5-dimension score; patient satisfaction; and walking distance/time and time to return to daily activities post-surgery. Surgical outcomes will include postoperative drainage, operative time, duration of hospital stay, postoperative creatine kinase level as an indicator of muscle injury, and postoperative scarring. Postoperative magnetic resonance imaging, computed tomography, and simple radiography will be performed to evaluate radiographic outcomes between the two surgical approaches. Surgery-related complications and adverse effects will be evaluated as safety outcomes. A single assessor at each participating hospital, blinded to group allocation, will assess the enrolled participants at baseline, at 2 weeks, and at 3, 6, and 12 months postoperatively. Discussion This trial is designed to determine whether interlaminar full-endoscopic discectomy is clinically comparable to microscopic discectomy to treat lumbar disc herniations. All efforts will be made to reduce bias, including adequate sample size, blinded analyses, and multicenter prospective registration. The outcomes will inform practice, providing the evidence needed for using interlaminar full-endoscopic over microscopic discectomy by confirming the potential of this technique to improve patient satisfaction and clinical outcomes.

Abstract
Nerve root morphological variability is often incompletely appreciated on preoperative imaging and can complicate intraoperative decision-making. This case demonstrates the utility of spinal endoscopy in the visualisation and manipulation of conjoined nerve roots and includes procedural images to promote better understanding and awareness of this anatomical anomaly. A woman in her 50s presented with 1 year of progressive left S1 radiculopathy refractory to non-operative modalities. History and examination were notable for S1 dermatomal paresthesias, positive ipsilateral straight leg raise and grade 4/5 gastrocnemius strength. MRI demonstrated an L5-S1 left paracentral disc herniation causing severe lateral recess stenosis. Endoscopic decompression revealed conjoined lumbosacral nerve roots. Laminotomies and discectomy provided circumferential decompression. The patient experienced immediate and sustained relief of her preoperative radiculopathy as manifested in patient-reported outcome measures. Evolving endoscopic spine platforms provide novel visualisation of nerve root anomalies yielding new insight on safe and effective decompressive techniques.

Abstract
BACKGROUND Percutaneous endoscopic lumbar foraminotomy (PELF) is a good alternative for foraminal stenosis. The steep learning curve and lack of a practical manual can make this technique challenging. METHOD We describe a step-by-step technique based on the literature review and our experience in actual practice: (1) posterolateral foraminal landing, (2) bony unroofing of the superior articular process, and (3) full-scale soft tissue decompression. Technical tips for preventing complications are also discussed. CONCLUSION PELF may be effective and minimally invasive. Standardized surgical techniques are essential for clinical success.

Abstract
Full-endoscopic lumbar discectomy (FED) is one of the least invasive procedures for lumbar disc herniation. Patients who receive FED for lumbar disc herniation may develop recurrent herniation at a frequency similar to conventional procedures. Reoperation and risk factors of recurrent lumbar disc herniation were investigated among 909 patients who received FED using an interlaminar approach (FED-IL). Sixty-five of the 909 patients received reoperation for recurrent herniation. Disc height, smoking, diabetes mellitus (DM), subligamentous extrusion (SE) type, and Modic change were identified as the risk factors for recurrence. Other indicators such as LL, Cobb angle, disc migration, age, sex, and body mass index (BMI) did not reach significance. Among 65 patients, reoperation was performed within 14 days following FED-IL (very early) in 7 patients, from 15 days to 3 months (early) in 14 patients, from 3 months to 1 year (midterm) in 17 patients, and after more than 1 year (late) in 27 patients. The very early group included a greater number of males, and the mean age was significantly lower in comparison to other groups. All patients in the very early group received FED-IL for reoperation. Reoperation within 2 weeks allows FED-IL to be performed without adhesion. Fusion surgery was performed on three cases in the early and midterm groups and on 10 cases in the late group, which increased over time as degenerative change and adhesion progressed. The procedure selected to treat recurrent herniation mostly depends on the surgeon’s preference. Revision FED-IL is the first choice for recurrent herniation in terms of minimizing surgical burden, whereas fusion surgery offers the advantage that discectomy can be performed through unscarred tissues. FED-IL is recommended for recurrent herniation within 2 weeks before adhesion progresses.

Abstract
A 74-year-old man presented with symptoms of intermittent claudication. A diagnosis of lumbar spinal canal stenosis (LSS) at L3/4 and L4/5 was made based on the clinical and radiological findings. Bilateral lateral recess stenosis was detected at both these levels on magnetic resonance imaging (MRI) and on computed tomography (CT) scans obtained after myelography. Four nerve roots were impinged bilaterally at L4 and L5. The initial plan was to perform conventional laminectomy at L3/4 and L4/5 under general anesthesia. However, the neurologists pointed out that the patient had comorbidities of parkinsonism and severe carotid artery stenosis, meaning that an increase or decrease in blood pressure during general anesthesia could cause a stroke. Therefore, we changed the surgical plan to four-stage full-endoscopic ventral facetectomy at L3/4 and L4/5 bilaterally under local anesthesia. There were no surgery-related complications after any of the four operations. The patient's symptoms improved after the final operation and the modified MacNab criteria indicated a good clinical outcome. Full-endoscopic lumbar decompression surgery under local anesthesia may be effective in elderly patients who are in poor general health.

Abstract
Degenerative disease of the intervertebral discs (DDD) is currently a serious problem facing the world community. The surgical methods and conservative therapy used today, unfortunately, do not stop the pathological process, but serve as a palliative method that temporarily relieves pain and improves the patient’s quality of life. Therefore, at present, there is an active search for new methods of treating DDD. Among new techniques of treatment, biological methods, and minimally invasive surgery, including the use of laser radiation, which, depending on the laser parameters, can cause ablative or modifying effects on the disc tissue, have acquired considerable interest. Here, we analyze a new approach to solving the DDD problem: laser tissue modification. This review of publications is focused on the studies of the physicochemical foundations and clinical applications of a new method of laser reconstruction of intervertebral discs. Thermomechanical action of laser radiation modifies tissue and leads to its regeneration as well as to a long-term restoration of disc functions, elimination of pain and the return of patients to normal life.

Abstract
BACKGROUND In this study, we systematically analyze the effectiveness of the uniportal full-endoscopic (UPFE) and minimally invasive (MIS) decompression for treatment of lumbar spinal stenosis patients. METHODS We performed a systematic search in Medline, Embase, Europe PMC, PubMed, Web of Science, Cochrane databases, Chinese Biomedical Literature Database, China national knowledge infrastructure, and Wanfang Data databases for all relevant studies. All statistical analyses were performed using Review Manager version 5.3. RESULTS A total of 9 articles with 522 patients in the UPFE group and 367 patients in the MIS group were included. The results of the meta-analysis showed that the UPFE group had significantly better results in hospital stay time (mean difference [MD]: -2.05; 95% confidence interval [CI]: -2.87 to -1.23), intraoperative blood loss (MD: -36.56; 95% CI: -54.57 to -18.56), and wound-related complications (MD: -36.56; 95%CI: -54.57 to -18.56) compared with the MIS group, whereas the postoperative clinical scores (MD: -0.66; 95%CI: -1.79 to 0.47; MD: -0.75; 95%CI: -1.86 to 0.36; and MD: -4.58; 95%CI: -16.80 to 7.63), satisfaction rate (odds ratio [OR] = 1.24; 95%CI: 0.70-2.20), operation time (MD: 30.31; 95%CI: -12.55 to 73.18), complication rates for dural injury (OR = 0.60; 95%CI: 0.29-1.26), epidural hematoma (OR = 0.60; 95%CI: 0.29-1.26), and postoperative transient dysesthesia and weakness (OR = 0.73; 95%CI: 0.36-1.51) showed no significant differences between the two groups. CONCLUSIONS The UPFE decompression is associated with shorter hospital stay time and lower intraoperative blood loss and wound-related complications compared with MIS decompression for treatment of lumbar spinal stenosis patients. The postoperative clinical scores, satisfaction rate, operation time, complication rates for dural injury, epidural hematoma, and postoperative transient dysesthesia and weakness did not differ significantly between two groups.

Abstract
ABSTRACT Objectives: To compare microdiscectomy (MD) and endoscopic interlaminar discectomy (EID) as methods for the surgical treatment of lumbar disc herniation, describing their efficiency in reducing hospitalization time, pain, and neurological deficit, and comparing the findings and the quality of studies that used the microscopic and endoscopic techniques. Methods: A systematic literature review that used the PRISMA protocol as a methodology. The search was conducted in the PUBMED/MEDLINE and The Cochrane Library databases, using publications from the last 5 years in Portuguese and English. After applying the inclusion and exclusion criteria and validating the qualified studies via STROBE and CONSORT, there were a total of 16 studies for data compilation. Results: A sample of 1004 patients who underwent lumbar discectomy was obtained, 62% of whom were male, and 493 of whom underwent EID (49%) and 511 MD (51%). The mean patient age was 38.7 years and the predominant vertebral level operated was L5-S1 (64.8%). The EID had shorter surgical time (66.38 min) and hospitalization time (3.3 days), in addition to greater variation in the VAS LLLL score (5.38), while the MD presented greater variation in the VAS LUMBAR score (3.14). Conclusion: EID demonstrated efficacy like that of MD, given the similarity in the results obtained, in addition to non-inferiority in the reduction of pain and neurological deficit, and superiority in surgical and hospitalization times.

Abstract
ABSTRACT Objective: To compare the differences between transforaminal and interlaminar endoscopic approaches in terms of pain intensity and functionality 30 days after the surgical procedure. Methods: A retrospective cohort study, with patients treated by percutaneous interlaminar or transforaminal endoscopic discectomy at the Spine Service of the ISCMPA, in southern Brazil. Data were collected from the patients’ electronic medical records by two independent physicians. The clinical outcomes of pain intensity and lumbar functionality were evaluated, respectively, using the visual analogue scale and the Oswestry Disability Index. Results: Thirty-six patients were included in the study, with a mean age of 50.8 ± 15.3 years, 19 (52.8%) of whom were males. As for the clinical outcomes for both transforaminal and interlaminar percutaneous endoscopic approaches, we observed a statistically significant reduction in pain intensity (mean difference of 3.5 points, p < 0.001) and a statistically significant improvement in functionality (mean difference of 33.2 points, p < 0.001) when we compared the pre- and 30-day postoperative periods, with no significant differences in terms of approaches. The type of technical approach also differed in relation to the patients’ age, the location, type, and migration of the herniated disc, and the patient’s time in the operating room. Conclusion: There was a similar effect on pain reduction and restoration of lumbar functions, 30 days after percutaneous endoscopic discectomy, in both technical approaches, with no significant differences between them. Level of Evidence III; Retrospective comparative study.

Abstract
Objective The purpose of this study was to introduce and evaluate the early clinical outcomes of the full-endoscopic posterior lumbar interbody fusion (Endo-PLIF) technique with epidural anesthesia (EA) for single-segment lumbar degenerative diseases. Methods In this retrospective case series study, we explored the feasibility and effectiveness of the Endo-PLIF with EA for single-segment lumbar degenerative diseases. Between March 2018 and January 2019, a series of 24 patients with single-segment lumbar degenerative diseases underwent Endo-PLIF surgery and were followed up for a minimum of 12 months (15.21±2.27 months). Clinical outcomes including visual analog scale (VAS) scores for back and leg pain, Oswestry Disability Index (ODI) scores, and the Short Form-36 health survey questionnaire (SF-36) were evaluated preoperatively, and postoperatively at 3 days and at 3, 6, and 12-months. Results All patients underwent successful single-segment Endo-PLIF surgery. The mean operation time was 209.17±39.49 min, and average amount of bleeding was 43.33±14.87 mL. The VAS for lower extremity pain and back pain significantly improved at 3 days, and at 3, 6, 12 months compared with preoperative, respectively. The ODI scores decreased from 42.04±3.96 to 12.75±2.71 (P<0.001) at preoperative and 12 months postoperatively, respectively. The SF-36 Physical Component Scores (PCS) improved from 34.96±4.63 preoperatively to 52.08±6.05 (P<0.001) at 12 months postoperatively. Additionally, the SF-36 Mental Component Scores (MCS) improved from 39.38±5.70 at preoperative to 53.13±5.97 (P<0.001) at 12 months postoperatively. Two patients experienced dysesthesia, and one patient had a wound infection. Conclusion Endo-PLIF with EA is a feasible and valuable technique for the treatment of single-segment lumbar degenerative diseases in selected patients.

Comparison of the Clinical Outcomes of Full-Endoscopic Visualized Foraminoplasty and Discectomy Versus Microdiscectomy for Lumbar Disc Herniation. Orthop Surg 2021; 14:280-289. [PMID: 34914186 PMCID: PMC8867436 DOI: 10.1111/os.13087] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/21/2021] [Revised: 04/15/2021] [Accepted: 05/10/2021] [Indexed: 12/25/2022] Open
Abstract
OBJECTIVE This retrospective case-control study aimed to evaluate and compare the clinical outcomes of full-endoscopic visualized foraminoplasty and discectomy (FEVFD) with microdiscectomy (MD) for lumbar disc herniation (LDH). METHODS Data from 198 patients who presented with LDH between January 2016 and December 2017 treated by either FEVFD or MD were retrospectively analyzed. The inclusion criteria were single-level LDH, unilateral radiating leg pain with or without positive Lasegue's sign, and failure of standard conservative treatment for at least 12 weeks. The patients were categorized into an FEVFD group (n = 102) or an MD group (n = 96), according to the surgical procedure performed. Operative time, time in bed after surgery, postoperative hospitalization time, complications, and reoperations were recorded. Visual analog scales (VAS) for leg and back pain, Oswestry Disability index (ODI), 36-Item Short-Form Health Survey physical function (SF36-PF), and bodily pain (SF36-BP) scores were assessed and compared between the two groups. RESULTS The demographic data and baseline characteristics of the two groups were not significantly different. Operative time for the FEVFD group (73.82 ± 20.73 min) was longer than that for the MD group (64.74 ± 17.37 min) (P = 0.003), and fluoroscopy time for the FEVFD group (1.71 ± 0.58s) was longer than that for the MD group (1.30 ± 0.33s) (P < 0.001). However, time in bed experienced in the FEVFD group (8.51 ± 2.10 h) was less than that in the MD group (9.24 ± 2.01 h) (P = 0.014), and postoperative hospitalization time experienced in the FEVFD group (2.89 ± 0.83d) was also shorter than that in the MD group (4.94 ± 1.35d) (P < 0.001). All patients completed 24 months of follow-up. Postoperative scores at each follow-up for the VAS for leg and back pain, ODI, SF36-PF, and SF36-BP all improved significantly for both groups, as compared to the preoperative data (P < 0.05). The mean preoperative and postoperative scores for the VAS for leg and back pain, ODI, SF36-PF, and SF36-BP were not significantly different between the two groups. According to the modified MacNab criteria, the outcomes of the procedures were rated as excellent or good by 92.16% and 93.75% of the patients in the FEVFD and MD groups, respectively. One patient suffered a nerve root injury during the discectomy, one patient suffered from a dural tear, and two patients suffered from a residual herniation in the FEVFD group. One patient in the MD group suffered from poor wound healing. Moreover, recurrence happened in two cases in the FEVFD group, and in one case in the MD group. CONCLUSION FEVFD and MD are both reliable techniques for the treatment of symptomatic LDH. FEVFD resulted in a more rapid recovery and equivalent clinical outcomes after 24 months of follow-up.

Abstract
OBJECTIVE To investigate the feasibility and efficacy of percutaneous transforaminal endoscopic discectomy (PTED) with three-step maneuver for puncture (TSMP) for lumbar herniated disc (LDH). METHODS We performed a retrospective review of 30 patients who underwent PTED using TSMP for LDH and met inclusion criteria from January 2018 to September 2018. The primary outcome, leg or back pain, was assessed using Visual Analogue Scale (VAS). Patient surgical satisfaction was measured at 12 months post surgery using a five-point Likert scale. Potential prognostic factors measured were demographic characteristics, duration of symptom (DOS), and involved levels. Statistical analysis was performed using Fisher exact test and t-test. TSMP is a three-step maneuver that builds on the concept of needle puncture site and trajectory determination based on the principles of Kambin's triangle. First, accurate direction of the puncture is confirmed by inserting the needle horizontally. Then by gradually raising the needle tail in the manner described, the superior articular facet and the intervertebral foramen are sequentially located. Finally, the needle tip slides into the intervertebral foramen to reach the target superior articular facet. RESULTS Preoperative mean VAS was 7.6 ± 1.19, which decreased to 1.4 ± 0.97 at 12 months following treatment (P < 0.0001). Rates of surgical satisfaction per Likert scale were as follows: very satisfied and satisfied in 26 patients (86.7%). Three recurrent disc herniations of adjacent segmental levels were observed in the L5-S1 group at eight and 12 months after surgery. VAS scores at 12 months varied significantly between L4-L5 level surgery and L5-S1 level surgery groups (P < 0.01). CONCLUSION TSMP is a reliable technique for puncture into the intervertebral foramen.

Unilateral Biportal Endoscopic Lumbar Interbody Fusion: A Technical Note and an Outcome Comparison with the Conventional Minimally Invasive Fusion. Orthop Res Rev 2021; 13:229-239. [PMID: 34853540 PMCID: PMC8628045 DOI: 10.2147/orr.s336479] [Citation(s) in RCA: 11] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/14/2021] [Accepted: 11/03/2021] [Indexed: 12/14/2022] Open
Abstract
Background In the past few decades, the minimally invasive technique for spine surgery has developed extensively from the scope of decompression until fusion surgeries to reduce damages to the normal anatomical structure. Unilateral biportal endoscopic lumbar interbody fusion (ULIF) is one of the fusion options which is readily available without a sophisticated minimal invasive instrument. Our aim is to introduce ULIF experience in our center and comparing the result with conventional minimally invasive lumbar interbody fusion (MIS-TLIF). Methods This is a retrospective cohort study of 145 lumbar spondylolisthesis cases that underwent fusion surgery with either ULIF or the conventional MIS-TLIF. All of the patients were observed within a 12-month follow-up period to evaluate the back pain and leg pain Visual Analogue Score (VAS), the Oswestry Disability Index (ODI), the 36-Item Short Form Health Survey (SF-36), and fusion rate. Results The leg pain VAS was similarly improved in both groups. ULIF has a significant back pain improvement on direct post operation and at the 3-months follow-up (p value 0.032 and 0.046 respectively). ULIF group also had a significantly better improvement of ODI scores on the early post-operative period (p=0.045). However, both groups similarly showed improvement of ODI score and the SF-36 at the 3-, 6-, and 12- months follow up. Conclusion Full endoscopic fusion surgery with ULIF offers a comparable long-term outcome and a significantly better back pain VAS reduction in short-term follow up compared to the conventional MIS-TLIF. ULIF, with further improvement, can be the next gold standard in managing degenerative lumbar spine conditions.

Abstract
Case summary A 2-year-old neutered female Scottish Fold cat was presented with an 8-week history of
progressive back pain, paraparesis and decrease of postural reactions in both pelvic
limbs. MRI showed spinal cord compression from both ventral sides, which originated from
the T4 vertebral body and pedicle. The lesion compressing the spinal cord had a
bone-like density on CT, and endoscopic surgery was performed to excise it.
Histopathological examination of the resected tissue showed no evidence of malignancy
and the lesion was diagnosed as vertebral hypertrophy. After surgery, the neurological
status of the cat gradually improved. The cat was ambulant at the follow-up evaluation 2
weeks after surgery. Six months later, hindlimb paresis had improved considerably, and
no recurrence was observed on CT. Relevance and novel information This is the first description of thoracic vertebral canal stenosis due to hypertrophy
of a single vertebra in a young cat. Excision of the hypertrophic vertebra by endoscopic
surgery is less invasive than open surgery and may give a good prognosis.

Abstract
OBJECTIVE We sought to introduce technical notes of full endoscopic lumbar interbody fusion (FE-LIF) with an anterior expandable cylindrical fusion cage. METHODS This study retrospectively reviewed patients who underwent FE-LIF with an anterior expandable cylindrical fusion cage through transforaminal or interlaminar approaches from August 2018 to April 2019. Patient demographics and operation-related complications were recorded. Clinical and radiologic outcomes were evaluated at 1 year after surgery. RESULTS A total of 32 patients (34 segments) were included in this study. Among them, 14 received full endoscopic transforaminal lumbar interbody fusion and 18 received full endoscopic interlaminar lumbar interbody fusion. There were significant differences in interbody fusion indications between the 2 groups (P < 0.05). All operations were successfully completed without complications. Postoperative lumbar magnetic resonance imaging showed that nerve decompression was sufficient in all patients, and the visual analog scale scores of low back pain and leg pain, the Oswestry Disability Index scores, and sensory and muscle strength were significantly improved after surgery (P < 0.01). The MacNab score included 9 excellent ratings, 4 good ratings, and 1 fair rating in the full endoscopic transforaminal lumbar interbody fusion group and included 10 excellent ratings and 8 good ratings in the full endoscopic interlaminar lumbar interbody fusion group; the scores were not significantly different between the 2 groups at 1 year after surgery (P > 0.05). Complete interbody fusion was achieved in both groups according to computed tomography at 1 year after surgery. CONCLUSIONS FE-LIF is a safe and effective minimally invasive lumbar surgery with an anterior expandable cylindrical fusion cage.

Medicine (Baltimore) 2021; 100:e27412. [PMID: 34622848 PMCID: PMC8500638 DOI: 10.1097/md.0000000000027412] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/02/2021] [Accepted: 09/17/2021] [Indexed: 01/05/2023] Open
Abstract
Transforaminal endoscopic lumbar discectomy (TELD) is useful for soft lumbar disc herniation (LDH). Although the transforaminal approach can reach the foraminal disc zone, the risk of exiting nerve root irritation along the path is considerable. Few studies have assessed the difficulties of TELD for foraminal LDH. The objective of this study is to compare the clinical results of TELD between foraminal or far-lateral LDH and paramedian LDH.Between June 2016 and July 2017, 135 consecutive patients with single-level LDH were treated with TELD for 2 years. Among them, 25 patients had foraminal or far-lateral LDH (foraminal group), and the remaining 110 patients had central or subarticular LDH (paramedian group). Perioperative data and clinical outcomes were evaluated using the visual analog pain scale, Oswestry Disability Index, and modified Macnab criteria.The foraminal group showed a higher rate of significant access pain (24.00% vs 8.19%, P < .05). The foraminal group also had a longer duration of surgery, length of hospital stay, and return to work (all P < .05). Pain scores and functional status were significantly improved in both groups. Although there were no differences in the outcomes at 2 years postoperatively, early pain and disability at 6 weeks were higher in the foraminal group.Ironically, the early clinical results of TELD for foraminal LDH may be less favorable than those for paramedian LDH. Therefore, great care should be taken during TELD for foraminal or far-lateral LDH.

Comparison of interventions for lumbar disc herniation: a systematic review with network meta-analysis. Spine J 2021; 21:1750-1762. [PMID: 33667683 DOI: 10.1016/j.spinee.2021.02.022] [Citation(s) in RCA: 14] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/27/2020] [Revised: 02/06/2021] [Accepted: 02/27/2021] [Indexed: 02/03/2023]
Abstract
BACKGROUND Implants for use in disc herniation surgery have been commercially available for some time. Several clinical trials have shown promising results. There are now a wide variety of surgical methods for treating lumbar disc herniation. PURPOSE The objective of this systematic review was to compare all current surgical methods for disc herniation, including newer methods with implants for annulus repair and dynamic stabilization. STUDY DESIGN Systematic review and network meta-analysis. METHODS PRISMA-P guidelines were followed in this review. Literature search in PubMed, Embase, and Cochrane library databases identified eligible randomized controlled trials (RCT) studies comparing interventions for lumbar disc surgery. The investigated outcomes were: changes in pain score, disability score and reoperation rate with a minimum follow-up of 1 year. Risk of bias was assessed in concordance with Cochrane Neck and Back Review Group recommendation. A network meta-analysis was performed using gemtc and BUGSnet software, and each outcome evaluated using Confidence in Network Meta-Analysis (CINeMA). RESULTS Thirty-two RCT studies, with 4,877 participants, and eight different interventions were identified. A significant difference was seen in change of pain score, as all treatments were superior to conservative treatment and percutaneous discectomy. This difference was only found to be of clinically importance when comparing conservative treatment and dynamic stabilization. There was no significant difference in reoperation rates or change in disability score, regardless of treatment. However, SUCRA plots showed a trend in ranking annulus repair and dynamic stabilization highest. Risk of bias assessment showed that 15 studies had a high overall risk of bias. Meta-regression with risk of bias as covariate did not indicate any influence in risk of bias on the model. Confidence in Network Meta-Analysis evaluation showed a high level of confidence for all treatment comparisons. CONCLUSIONS With this network meta-analysis, we have aimed to compare all treatments for herniated lumbar disc in one large comprehensive systematic review and network meta-analysis. We have compared across the three main outcomes: disability score, pain score and reoperation rate. We were not able to rank one single treatment as the best. Most of the treatment performed at the same level. However percutaneous discectomy and conservative treatment consistently performed worse than the other treatments. In general, the CINeMA evaluation according to the GRADE recommendations gave a high level of confidence for the study comparisons.

A 2-Year Outcomes and Complications of Various Techniques of Lumbar Discectomy: A Multicentric Retrospective Study. World Neurosurg 2021; 156:e319-e328. [PMID: 34555576 DOI: 10.1016/j.wneu.2021.09.062] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/21/2021] [Revised: 09/12/2021] [Accepted: 09/13/2021] [Indexed: 12/13/2022]
Abstract
OBJECTIVES Various techniques of performing lumbar discectomy are prevalent, each having its rationale and claimed benefits. The authors ventured to assess the perioperative factors, outcomes, and complications of each procedure and compare among them with 946 patients contributed by 10 centers and operated by experienced surgeons. METHODS This was a retrospective study of patients operated using open discectomy, microdiscectomy, microendoscopic discectomy, interlaminar endoscopic lumbar discectomy, transforaminal endoscopic lumbar discectomy, and Destandau techniques with a follow-up of minimum 2 years. The inclusion criteria were age >18 years, failed conservative treatment for 4-6 weeks, and the involvement of a single lumbar level. RESULTS There was a significant improvement in the visual analog scale score of back, leg, and Oswestry Disability Index scores postoperatively across the board, with no significant difference between them. Minimally invasive procedures (microendoscopic discectomy, interlaminar endoscopic lumbar discectomy, transforaminal endoscopic lumbar discectomy, and Destandau techniques) had shorter operation time, hospital stay, better cosmesis, and decreased blood loss compared with open procedures (open discectomy and microdiscectomy). The overall complication rate was 10.1%. The most common complication was recurrence (6.86%), followed by reoperation (4.3%), cerebrospinal fluid leak (2.24%), wrong level surgery (0.74%), superficial infection (0.62%), and deep infection (0.37%). There were minor differences in incidence of complications between techniques. CONCLUSION Although minimally invasive techniques have some advantages over the open techniques in the perioperative factors, all the techniques are effective and provide similar pain relief and functional outcomes at the end of 2 years. The various rates of individual complications provide a reference value for future studies.

Abstract
STUDY DESIGN Systematic review and meta-analysis. OBJECTIVES We performed this meta-analysis to evaluate whether endoscopic discectomy (ED) shows superiority compared with the current gold standard of microdiscectomy (MD) in management of lumbar disc disease. MATERIALS AND METHODS We conducted independent and duplicate electronic database search including PubMed, Embase, and Cochrane Library from 1990 till April 2020 for studies comparing ED and MD in the management of lumbar disc disease. Analysis was performed in R platform using OpenMeta[Analyst] software. RESULTS We included 27 studies, including 11 randomized controlled trials (RCTs), 7 nonrandomized prospective, and 9 retrospective studies involving 4018 patients in the meta-analysis. We stratified the results based on the study design. Considering the heterogeneity in some results between study designs, we weighed our conclusion essentially based on results of RCTs. On analyzing the RCTs, superiority was established at 95% confidence interval for ED compared with MD in terms of functional outcomes like Oswestry Disability Index (ODI) score (P = .008), duration of surgery (P = .023), and length of hospital stay (P < .001) although significant heterogeneity was noted. Similarly, noninferiority to MD was established by ED in other outcomes like visual analogue scale score for back pain (P = .860) and leg pain (P = .495), MacNab classification (P = .097), recurrences (P = .993), reoperations (P = .740), and return-to-work period (P = .748). CONCLUSION Our meta-analysis established the superiority of endoscopic discectomy in outcome measures like ODI score, duration of surgery, overall complications, length of hospital stay and noninferiority in other measures analyzed. With recent advances in the field of ED, the procedure has the potential to take over the place of MD as the gold standard of care in management of lumbar disc disease.

Abstract
Aim: Endoscopic discectomies provide several advantages over other techniques such as traditional open lumbar discectomy (OLD) including possibly decreased complications, shorter hospital stay and an earlier return to work. Methods: An electronic database search including MEDLINE/PubMed, EMBASE, Scopus, Cochrane Database of Systematic Reviews and Cochrane Controlled trials (CENTRAL) were reviewed for randomized controlled trials (RCTs) only. Results: A total of nine RCTs met inclusion criteria. Three showed benefit of endoscopic discectomy over the comparator with regards to pain relief, with the remaining six studies showing no difference in pain relief or function. Conclusion: Based on review of the nine included studies, we can conclude that endoscopic discectomy is as effective as other surgical techniques, and has additional benefits of lower complication rate and superior perioperative parameters.

Abstract
OBJECTIVE The objective of this study is to compare the clinical outcome among patients who are surgically treated for lumbar disc herniation by transforaminal and interlaminar endoscopy techniques. METHODS For the treatment of lumbar disc herniation, 31 patients were assigned to undergo the interlaminar technique and 24 patients the transforaminal technique. They were evaluated using visual analog scale and Oswestry disability index in the preoperative period, in the first postoperative period, and in the 12th month after the procedure. The clinical results between the two techniques were then compared. RESULTS Overall, 89.1% of the patients obtained good results, with 12.5% complications in the transforaminal technique and 9.6% in the interlaminar technique. CONCLUSION Although both the endoscopic techniques, compared in this study, are safe and effective for the surgical treatment of lumbar herniated disc, the interlaminar technique presented significantly better results and lower rates of complications than the transforaminal technique.

BMC Musculoskelet Disord 2021; 22:693. [PMID: 34391400 PMCID: PMC8364045 DOI: 10.1186/s12891-021-04548-3] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/19/2021] [Accepted: 07/26/2021] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Percutaneous endoscopic lumbar discectomy (PELD) has become popular for the treatment of symptomatic lumbar disc herniation (LDH). The very highly up-migrated lumbar disc herniation (VHUM-LDH) is difficult to remove under PELD. The purpose of this research is to investigate the feasibility, clinical efficacy and operative nuances of a novel VTT involving TELF for this type of herniation. METHODS Eleven patients with very highly up-migrated LDH who underwent VTT involving TELF discectomy from May 2016 to May 2019 were included in this study. The operative time, length of hospital stay, and postoperative complications were recorded. Pre-and postoperative radiologic findings were investigated. All the patients were followed more than 1 year. The visual analogue score (VAS), Oswestry Disability Index (ODI), Japanese Orthopaedic Association (JOA) scores and modified MacNab criteria were used to assess surgical efficacy. RESULTS All the 11 patients underwent successful surgery. We compared the VAS, ODI, and JOA scores before and after surgery. The differences were statistically significant (P < 0.05). According to the modified MacNab criteria, 10 patients were assessed as "excellent", 1 patient was assessed as "good" at the last follow up. CONCLUSION The novel VTT involving TELF discectomy is a supplement to the traditional PELD. This technique enables the endoscope with working cannula to get closer the sequestrated nucleus pulposus without irritating the exiting nerve root, and facilitates the nucleus pulposus be removed successfully under direct visualization. The VTT involving TELF discectomy can be a safe, effective and feasible surgical procedure for the treatment of LDH with very highly up-migrated.

Abstract
AIMS Open discectomy (OD) is the standard operation for lumbar disc herniation (LDH). Percutaneous endoscopic lumbar discectomy (PELD), however, has shown similar outcomes to OD and there is increasing interest in this procedure. However despite improved surgical techniques and instrumentation, reoperation and infection rates continue and are reported to be between 6% and 24% and 0.7% and 16%, respectively. The objective of this study was to compare the rate of reoperation and infection within six months of patients being treated for LDH either by OD or PELD. METHODS In this retrospective, nationwide cohort study, the Korean National Health Insurance database from 1 January 2007 to 31 December 2018 was reviewed. Data were extracted for patients who underwent OD or PELD for LDH without a history of having undergone either procedure during the preceding year. Individual patients were followed for six months through their encrypted unique resident registration number. The primary endpoints were rates of reoperation and infection during the follow-up period. Other risk factors for reoperation and infection were also evalulated. RESULTS Out of 549,531 patients, 522,640 had undergone OD (95.11%) and 26,891 patients had undergone PELD (4.89%). Reoperation rates within six months were 2.28% in the OD group, and 5.38% in the PELD group. Infection rates were 1.18% in OD group and 0.83% in PELD group. The risk of reoperation was lower for patients with OD than for patients with PELD (adjusted hazard ratio (HR) 0.38). The risk of infection was higher for patients with OD than for patients undergoing PELD (HR, 1.325). CONCLUSION Compared with the OD group, the PELD group showed higher reoperation rates and lower infection rates. Cite this article: Bone Joint J 2021;103-B(8):1392-1399.

Abstract
PURPOSE Knowledge of interlaminar space is important for undertaking percutaneous endoscopic discectomy via an interlaminar approach (PED-IL). However, dynamic changes in the lumbar interlaminar space and the spatial relationship between the interlaminar space and intervertebral disc space (IDS) are not clear. The aim of this study was to anatomically clarify the changes in interlaminar space height (ILH) and variation in distance between the two spaces during flexion-extension of the lumbar spine in vitro. METHODS First, we used a validated custom-made loading equipment to obtain neutral, flexion, and extension 3D models of eight lumbar specimens through 3D reconstruction software. Changes in ILH (ILH, IL-yH, IL-zH) and distances between the horizontal plane passing through the lowest edge of the lamina of the superior lumbar vertebrae and the horizontal plane passing through the lowest position of the trailing edge of the same-level IDS (DpLID) at L3/4, L4/5 and L5/S1 were examined on 3D lumbar models. RESULTS We found that ILH was greater at L4/5 than at L3/4 and L5/S1 in the neutral position, but the difference was not significant. In the flexion position, ILH was significantly more than that in neutral and extension positions at L3/4, L4/5, and L5/S1. There were significantly more DpLID changes from neutral to flexion than that from neutral to extension at all levels (L3/4, L4/5, L5/S1). CONCLUSION These findings demonstrated level-specific changes in ILH and DpLID during flexion-extension. The data may provide a better understanding of the spatial relationship between lumbar interlaminar space and IDS, and aid the development of segment-specific treatment for PED-IL.

Abstract
Objective: Therapeutic options for lumbar disc surgery (LDH) have been rapidly evolved worldwide. Conventional pair meta-analysis has shown inconsistent results of the safety of different surgical interventions for LDH. A network pooling evaluation of randomized controlled trials (RCT) was conducted to compare eight surgical interventions on complications for patients with LDH. Methods: PubMed, Embase, and the Cochrane Central Register of Controlled Trials (CENTRAL) were searched for RCT from inception to June 2020, with registration in PROSPERO (CRD42020176821). This study is conducted in accordance with Cochrane guidelines. Primary outcomes include intraoperative, post-operative, and overall complications, reoperation, operation time, and blood loss. Results: A total of 27 RCT with 2,948 participants and eight interventions, including automated percutaneous lumbar discectomy (APLD), chemonucleolysis (CN), microdiscectomy (MD), micro-endoscopic discectomy (MED), open discectomy (OD), percutaneous endoscopic lumbar discectomy (PELD), percutaneous laser disc decompression (PLDD), and tubular discectomy (TD) were enrolled. The pooling results suggested that PELD and PLDD are with lower intraoperative and post-operative complication rates, respectively. TD, PELD, PLDD, and MED were the safest procedures for LDH according to complications, reoperation, operation time, and blood loss. Conclusion: The results of this study provided evidence that PELD and PLDD were with lower intraoperative and post-operative complication rates, respectively. TD, PELD, PLDD, and MED were the safest procedures for LDH according to complications, reoperation, operation time, and blood loss. Systematic Review Registration: PROSPERO, identifier CRD42020176821.

Abstract
OBJECTIVES The aim of this retrospective case study was to analyze the outcomes of minimal nerve root retraction in patients with impending neurologic deficit in degenerative lumbar spine disease using the full-endoscopic spine surgery. MATERIALS AND METHODS Thirty-seven consecutive patients with impending neurologic deficit underwent endoscopic spine surgery through either the transforaminal or the interlaminar approach. Their clinical outcomes were evaluated with visual analog scale (VAS) leg pain score, Oswestry Disability Index (ODI), and MacNab's criteria. The outcome of motor deficitis was evaluated with the Medical Research Council (MRC) grade. Completeness of decompression was documented with a postoperative magnetic resonance imaging (MRI) and computed tomography (CT) scan. RESULTS A total of 40 lumbar levels of 37 patients were operated, VAS score of the leg improved from 7.7 ± 1 to 1.9 ± 0.6 (p < 0.0001). ODI score improved from 74.7 ± 6.5 to 25.4 ± 3.49 (p < 0.0001). Motor weakness improved significantly immediately after surgery. The mean MRC grade increased to 1.97, 3.65, 4.41, and 4.76 preoperatively, at 1 week, at 3 months, and at the final follow-up, respectively, and all the patients with foot drop and cauda equina syndrome symptom recovered completely. One patient with great toe drop recovered partially to MRC grade 3. Mean follow-up of the study was 13.3 ± 6.1 months. According to MacNab's criteria, 30 patients (80.1%) had good and 7 patients (18.9%) had excellent results. Three patients required revision surgery. CONCLUSIONS Minimal nerve root retraction during full-endoscopic spine surgery is safe and effective for treatment of the impending neurologic deficit. We could achieve a thorough decompression of the affected nerve root with acceptable clinical outcome and minimal postoperative morbidity.

Percutaneous Endoscopic Interlaminar Discectomy with Modified Sensation-Motion Separation Anesthesia for Beginning Surgeons in the Treatment of L5-S1 Disc Herniation. J Pain Res 2021; 14:2039-2048. [PMID: 34267548 PMCID: PMC8275187 DOI: 10.2147/jpr.s306319] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/11/2021] [Accepted: 06/30/2021] [Indexed: 11/30/2022] Open
Abstract
Purpose To compare the clinical effects of local anesthesia (LA), general anesthesia (GA) and modified sensation-motion separation anesthesia (MA) in percutaneous endoscopic interlaminar discectomy (PEID) in the treatment of L5/S1 lumbar disc herniation (LDH) for the purpose of guiding junior surgeons. Methods Eighty-four patients with L5/S1 LDH underwent PEID using three anesthesia methods. Patients in the LA (26), GA (29) and MA (29) groups received a follow-up examination retrospectively. The general parameters, preparation and anesthesia duration, operative duration, recovery time, incidence of complications, ambulation time, length of hospital stay, incidence of severe complications, and reoperation rate were compared, and clinical outcomes were analyzed using a visual analog scale (VAS), the Oswestry Disability Index (ODI), and the Short-Form Health Survey 36 (SF-36). Results MA demonstrated obvious advantages over the other two methods with respect to operative duration and resulted in a better intraoperative experience than LA. The patients in the MA group required less time in bed postoperatively and shorter hospital stays than those in the GA group. The mean postoperative VAS, ODI and SF-36 scores were significantly better than the preoperative scores in all groups (P<0.05), but no significant differences in these scores were found among the three groups (P>0.05). Three cases (3/29) of nervous disorder occurred in the GA group. Two patients (one in the GA group (1/29) and one in the LA (1/26) group) underwent revision surgery, with a total recurrence rate of 2.4% (2/84). Conclusion Due to its high safety and good tolerance by patients, MA is a suitable method for spinal surgeons who are inexperienced with PEID in the treatment of L5/S1 disc herniation.

Thoracolumbar Interfascial Plane Block Results in Opioid-Free Postoperative Recovery After Percutaneous/Endoscopic Transforaminal Lumbar Interbody Fusion Surgery. World Neurosurg 2021; 153:e473-e480. [PMID: 34242827 DOI: 10.1016/j.wneu.2021.06.152] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/23/2021] [Revised: 06/29/2021] [Accepted: 06/30/2021] [Indexed: 02/02/2023]
Abstract
OBJECTIVE To evaluate efficacy in reducing postoperative pain and opioid analgesia of a novel interdisciplinary strategy combining preoperative thoracolumbar interfascial plane (TLIP) block and percutaneous/endoscopic transforaminal lumbar interbody fusion surgery and to determine time to first postoperative ambulation and hospital length of stay. METHODS In this retrospective review, 42 patients who underwent elective single-level percutaneous/endoscopic transforaminal lumbar interbody fusion surgery between 2015 and 2021 were divided into 2 groups: TLIP group with 17 patients who underwent TLIP block and non-TLIP group with 25 patients. Both groups received the same postoperative analgesia with morphine as patient-controlled rescue medication. Visual analog scale and Oswestry Disability Index scores were evaluated. Statistical evaluation was performed with Student t test. RESULTS In contrast to the non-TLIP group, in the TLIP group, postoperative mean visual analog scale back score and mean Oswestry Disability Index score significantly decreased from 6.6 to 3.3 (P < 0.01) and 32.8 to 23.6 (P < 0.01), respectively, at hospital discharge. No differences were found between the groups at 1 month. Overall mean follow-up time was 29 ± 18 months (range, 3-78 months). Patients in the non-TLIP group were administered a median postoperative 24-hour morphine dose equivalent of 23 mg (range, 8-31 mg), while patients in the TLIP group did not require opioid analgesia (P < 0.01). Patients in the TLIP group started postoperative ambulation at a median of 4.1 hours (range, 2.5-26 hours) with a median hospital length of stay of 24 hours (range, 20-48 hours) (P = 0.112). CONCLUSIONS TLIP block significantly improves patient outcome at hospital discharge after transforaminal lumbar interbody fusion surgery without postoperative administration of opioids. A prospective study is recommended to confirm our preliminary results.

Abstract
INTRODUCTION Diagnosis is the key to improving spinal surgery outcomes. Improvements in the diagnosis of radiculopathy have created new indications for full-endoscopic spine surgery. We assessed the finite element method (FEM) to visualize and digitize lesions not detected by conventional diagnostic imaging. METHODS We used FEM in two patients: a lumbar patient and a cervical patient. The lumbar patient was a 67-year-old woman with a history of rheumatoid arthritis; she also had osteoporosis and pulmonary fibrosis. She had left L3 radiculopathy due to an L3 vertebral fracture. The cervical patient was a 61-year-old woman with left C6 radiculopathy due to C5-C6 disc herniation. We performed full endoscopic foraminotomy per the patients's request. Based on preoperative and postoperative CT Digital Imaging and Communications in Medicine data of 0.5-mm slices, 3-D imaging data were reproduced, and kinetic simulation of FEM was performed. RESULTS Postoperatively, both patients' radiculopathy disappeared, improving their activities of daily living and enabling them to walk and work. Also, the total contact area and maximum contact pressure of the nerve tissue decreased from 30% to 80% and from 33% to 67%, respectively. CONCLUSIONS A new method for perioperative evaluation and simulation, FEM can be to visualize and digitize the conditions of the lesion causing radiculopathy. FEM that can overcome both time and economic constraints in routine clinical practice is needed.

Abstract
RATIONALE For isthmic lumbar spondylolisthesis (ILS) associated with the removal of herniation, it remains challenging to perform less invasive and minimally disruptive procedures. Good results could potentially be obtained by further preserving the posterior elements in full-endoscopic lumbar discectomy (FESS), which is less invasive than microenscopic surgery (MES). PATIENT CONCERNS One patient complained of left leg pain, and another patient complained of right leg pain and low back pain. DIAGNOSES Two patients with ILS and Meyerding Grade 1 lumbar spondylolisthesis. INTERVENTIONS We performed a full-endoscopic lumbar discectomy via the interlaminar space (FESS-IL) for L5/S1 lumbar disc herniation (LDH) accompanied by isthmic lumbar spondylolisthesis. FESS-IL was performed in 2 patients with radiculopathy caused by different types of LDH using a full endoscopic system with a 4.1 mm working channel and 6.9 mm outer diameter. A 3.5-mm diameter high-speed drill was used in one patient for an upward-migrated LDH in the inner-rim of the infravertebral border. The other patient underwent minimal resection without bone resection. OUTCOMES The one-year clinical outcome included confirmation of pain relief and evacuation of migrated LDH on magnetic resonance imaging in all patients. There was no progression of slippage on radiography. The mean operative time was 82 min, and no complication was observed. The one-year clinical outcome demonstrated sufficient pain relief. LESSONS THE Y ear postoperative outcome showed improvement. We believe that FESS-IL is a viable alternative operative approach for LDH for ILS.

Abstract
BACKGROUND Endoscopic spine surgery is an alternative to the traditional treatment of lumbar disc herniation. However, the traditional technique of interlaminar endoscopic approach is challenging and risky in patients with concomitant spinal stenosis. OBJECTIVE To report a modified technique called hybrid interlaminar endoscopic lumbar decompression as an effective treatment. METHODS Patients with combined lumbar disc herniation and lateral recess stenosis undergoing full-endoscopic interlaminar lumbar discectomy were retrospectively studied. The hybrid interlaminar endoscopic discectomy technique, as well as the use of 2 endoscopes with different diameters, is described in detail. The large endoscope is used for the laminotomy procedure, while the small endoscope is used for the discectomy procedure. The demographics and clinical outcomes of the patients are presented. RESULTS A total of 19 patients were included in this study. The mean age was 46.7 yr. The visual analog scale for back and leg pain improved from 5.6 ± 3.4 and 7.5 ± 2.3 to 1.8 ± 1.3 and 1.8 ± 1.6, respectively (P < .001). The mean Oswestry Disability Index improved from 59.9 ± 21.2 preoperatively to 18.2 ± 8.5 postoperatively (P < .001). The follow-up was 8.2 mo on average. No major complications occurred, but 2 patients reported mild postoperative paresthesia. One patient had an early recurrence and underwent repeat endoscopic discectomy. CONCLUSION Full-endoscopic lumbar discectomy provides excellent access to the intracanalicular herniation site of an intervertebral disc. By using the endoscopic technique presented here, surgeons can safely and efficiently achieve adequate decompression in patients with lumbar disc herniation combined with spinal stenosis.

Abstract
Recently, spine surgery has gradually evolved from conventional open surgery to minimally invasive surgery, and endoscopic spine surgery (ESS) has become an important procedure in minimally invasive spine surgery. With improvements in the optics, spine endoscope, endoscopic burr, and irrigation pump, the indications of ESS are gradually widening from lumbar to cervical and thoracic spine. ESS was not only used previously for disc herniations that were contained without migration but is also used currently for highly migrated disc herniations and spinal stenosis; thus, the indications of ESS will be further expanded. Although ESS has certain advantages such as less soft tissue dissection and muscle trauma, reduced blood loss, less damage to the epidural blood supply and consequent less epidural fibrosis and scarring, reduced hospital stay, early functional recovery, and improvement of quality of life as well as better cosmesis, several obstacles remain for ESS to be widespread because it has a steep learning curve and surgical outcome is strongly dependent on the surgeon's skillfulness. A solid surgical technique requires reproducibility and ensured safety in addition to surgical outcomes. In this review article, how to improve ESS was investigated by grafting novel technologies such as navigation, robotics, and 3-dimensional and ultraresolution visualization.

Abstract
Purpose Percutaneous endoscopic lumbar discectomy for the treatment of far-migrated lumbar disc herniation (LDH) is clinically challenging. The aim of this study was to compare the efficacy and safety of interlaminar endoscopic lumbar discectomy (IELD) and interlaminar microscopic lumbar discectomy (IMLD) for the treatment of far-migrated LDH. Materials and Methods We retrospectively analyzed 50 consecutive cases of far-migrated LDH treated by IELD or IMLD. Clinical data and outcomes were assessed before the operation and 1 day and 3, 12, and 24 months after the surgery using the visual analog scale (VAS) and Oswestry disability index (ODI). Modified MacNab criteria were used to evaluate patient satisfaction at the 24-month follow-up. Results A significant reduction in leg pain and improvement in ODI (P<0.01) were observed in both groups after surgery. Lower back pain (LBP) was reduced at 24 months postsurgery in the IELD group (P<0.05) but not in the IMLD group (P>0.05). There were significant intergroup differences in VAS LBP score at 1 day and 24 months postsurgery (p=0.01 and 0.02, respectively) and in ODI at 24 months (p=0.03). The rate of excellent or good outcome was 90.32% with IELD and 78.95% with IMLD (p=0.55). Hospital stay and time to ambulation were shorter in the IELD group than in the IMLD group, but the former had a longer operative time (p<0.01). Low and comparable complication rates were reported in the IELD (16.13%) and IMLD (10.53%) groups (p=0.70). Conclusion Both IELD and IMLD achieve favorable clinical results in the treatment of far-migrated LDH, with only minor complications. Compared to IMLD, LBP was significantly reduced with IELD presumably because it involved less trauma.

Abstract
OBJECTIVE to validate a lumbar spine endoscopic flavectomy simulator using the construct method and to assess the acceptability of the simulator in medical education. METHODS thirty medical students and ten video-assisted surgery experienced orthopedists performed an endoscopic flavectomy procedure in the simulator. Time, look-downs, lost instruments, respect for the stipulated edge of the ligamentum flavum, regularity of the incision, GOALS checklist (Global Operative Assessment of Laparoscopic Skills), and responses to the Likert Scale adapted for this study were analyzed. RESULTS all variables differed between groups. Procedure time was shorter in the physician group (p < 0.001). Look-downs and instrument losses were seven times greater among students than physicians. Half of the students respected the designated incision limits, compared to 80% of the physicians. In the student group, about 30% of the incisions were regular, compared to 100% in the physician group (p < 0.001). The physicians performed better in all GOALS checklist domains. All the physicians and more than 96% of the students considered the activity enjoyable, and approximately 90% believed that the model was realistic and could contribute to medical education. CONCLUSIONS the simulator could differentiate the groups' experience level, indicating construct validity, and both groups reported high acceptability.

Abstract
OBJECTIVE Sciatica is the hallmark symptom of a lumbar disc herniation (LDH). Up to 90% of LDH patients recover within 12 weeks regardless of treatment. With continued deteriorating symptoms and low patient quality of life, most surgeons recommend surgical discectomy. However, there is not yet a clear consensus regarding the proper timing of surgery. The aim of this study was to evaluate how the duration of preoperative leg pain (sciatic neuralgia) is associated with patient-reported levels of postoperative leg pain reduction and other patient-reported outcome measures (PROMs) in a prospectively collected data set from a large national cohort. METHODS All patients aged 18-65 years undergoing a lumbar discectomy during 2013-2016 and registered in Swespine (the Swedish national spine registry) with 1 year of postoperative follow-up data were included in the study (n = 6216). The patients were stratified into 4 groups according to preoperative pain duration: < 3, 3-12, 12-24, or > 24 months. Patient results assessed with the numeric rating scale (NRS) for leg pain (rated from 0 to 10), global assessment of leg pain, EQ-5D, Oswestry Disability Index (ODI), and patient satisfaction with the final surgical outcome were analyzed and compared with preoperative values and between groups. RESULTS A significant improvement was seen 1 year postoperatively regardless of preoperative pain duration (change in NRS score: mean -4.83, 95% CI -4.73 to -4.93 in the entire cohort). The largest decrease in leg pain NRS score (mean -5.59, 95% CI -5.85 to -5.33) was seen in the operated group with the shortest sciatica duration (< 3 months). The patients with a leg pain duration in excess of 12 months had a significantly higher risk of having unchanged radiating leg pain 1 year postoperatively compared with those with < 12-month leg pain duration at the time of surgery (OR 2.41, 95% CI 1.81-3.21, p < 0.0001). CONCLUSIONS Patients with the shortest leg pain duration (< 3 months) reported superior outcomes in all measured parameters. More significantly, using a 12-month pain duration as a cutoff, patients who had a lumbar discectomy with a preoperative symptom duration < 12 months experienced a larger reduction in leg pain and were more satisfied with their surgical outcome and perception of postoperative leg pain than those with > 12 months of sciatic leg pain.

Abstract
STUDY DESIGN Systematic review and meta-analysis. OBJECTIVE To give a systematic overview of effectiveness of percutaneous transforaminal endoscopic discectomy (PTED) compared with open microdiscectomy (OM) in the treatment of lumbar disk herniation (LDH). SUMMARY OF BACKGROUND DATA The current standard procedure for the treatment of sciatica caused by LDH, is OM. PTED is an alternative surgical technique which is thought to be less invasive. It is unclear if PTED has comparable outcomes compared with OM. METHODS Multiple online databases were systematically searched up to April 2020 for randomized controlled trials and prospective studies comparing PTED with OM for LDH. Primary outcomes were leg pain and functional status. Pooled effect estimates were calculated for the primary outcomes only and presented as standard mean differences (SMD) with their 95% confidence intervals (CI) at short (1-day postoperative), intermediate (3-6 months), and long-term (12 months). RESULTS We identified 2276 citations, of which eventually 14 studies were included. There was substantial heterogeneity in effects on leg pain at short term. There is moderate quality evidence suggesting no difference in leg pain at intermediate (SMD 0.05, 95% CI -0.10-0.21) and long-term follow-up (SMD 0.11, 95% CI -0.30-0.53). Only one study measured functional status at short-term and reported no differences. There is moderate quality evidence suggesting no difference in functional status at intermediate (SMD -0.09, 95% CI -0.24-0.07) and long-term (SMD -0.11, 95% CI -0.45-0.24). CONCLUSION There is moderate quality evidence suggesting no difference in leg pain or functional status at intermediate and long-term follow-up between PTED and OM in the treatment of LDH. High quality, robust studies reporting on clinical outcomes and cost-effectiveness on the long term are lacking.Level of Evidence: 2.

Percutaneous Endoscopic Lumbar Discectomy via Transforaminal Approach Combined with Interlaminar Approach for L4/5 and L5/S1 Two-Level Disc Herniation. Orthop Surg 2021; 13:979-988. [PMID: 33821557 PMCID: PMC8126944 DOI: 10.1111/os.12862] [Citation(s) in RCA: 18] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/26/2020] [Revised: 10/07/2020] [Accepted: 10/18/2020] [Indexed: 12/14/2022] Open
Abstract
Objective The purpose of the present study was to discuss a new surgical strategy that combines percutaneous endoscopic transforaminal discectomy (PETD) with percutaneous endoscopic interlaminar discectomy (PEID) for L4/5 and L5/S1 two‐level disc herniation. Methods This was a retrospective study. A total of 19 patients with L4/5 and L5/S1 two‐level lumbar disc herniation (LDH) who underwent percutaneous endoscopic lumbar discectomy (PELD) in our hospital from January 2015 to June 2016 were retrospectively examined. The average age of these 19 patients was 42.21 ± 14.88 years old, including 12 men and 7 women. One experienced surgeon who had carried out more than 3000 lumbar surgeries performed PELD for these patients. During the PELD surgery, the transforaminal approach was adopted for L4/5 level disc herniation and the interlaminar approach was adopted for L5/S1 level disc herniation. The demographic data, operation time (min), fluoroscopy times, hospital stay (days), and complications were recorded and analyzed. The visual analogue scale (VAS), Oswestry disability index (ODI) scores, and the modified MacNab criteria were used to evaluate the surgical outcomes. MRI was conducted to evaluate the radiographic improvement. Results All patients underwent PELD via the transforaminal approach combined with the interlaminar approach successfully and achieved satisfactory efficacy. The follow‐up points were 3, 12, and 18 months. The average hospital stay (days) and the average follow up (months) were 3.32 ± 0.98 and 18.63 ± 3.84, respectively. The operation time and fluoroscopy times were 85.79 ± 12.90 min and 39.05 ± 4.59 times, respectively. The fluoroscopy times (frequency) for L4/5 and L5/S1 were 26.95 ± 6.41 and 12.11 ± 3.49 (t = 7.00, P < 0.05). Furthermore, there was no significant difference for fluoroscopy times between male and female patients (t = 0.89, P = 0.99). The preoperative back pain (VAS‐Back) and the last follow‐up VAS‐Back were 5.58 ± 2.01 and 2.37 ± 1.01, respectively (t = 7.14, P < 0.05). The preoperative leg pain (VAS‐Leg) and the last follow‐up VAS‐Leg were 7.00 ± 1.56 and 1.63 ± 1.01, respectively (t = 20.97, P < 0.05). There were significant differences between preoperative VAS‐Back and the last follow‐up VAS‐Back in men (t = 4.61, P < 0.05) and women (t = 6.57, P < 0.05). In addition, there was significant differences between preoperative VAS‐Leg and the last follow‐up VAS‐Leg in men (t = 13.48, P < 0.05) and women (t = 26.87, P < 0.05). There were significant differences between preoperative ODI scores (44.84 ± 10.82%) and the last follow‐up ODI scores (11.12 ± 5.80%) (t = 10.92, P < 0.05). Preoperative ODI scores and the last follow‐up ODI scores were significantly different for men (t = 8.80, P < 0.05) and women (t = 6.63, P < 0.05). All patients received significant pain relief and functional improvement after the surgery. Except for two cases of postoperative dysesthesia and one dural tear, no severe complications occurred. The dysesthesia symptoms of these two patients disappeared within 1 week with the application of dexamethasone and neurotrophic drugs and the dural tear case also recovered well as the dural laceration was small. No poor results were reported and 89.47% of patients achieved excellent or good recovery. Conclusion Percutaneous endoscopic lumbar discectomy via the transforaminal approach combined with the interlaminar approach under epidural anesthesia can treat L4/5 and L5/S1 two‐level disc herniation safely and effectively.

Ahn Y, Lee S, Son S, Kim H. Learning Curve for Interlaminar Endoscopic Lumbar Discectomy: A Systematic Review. World Neurosurg 2021; 150:93-100. [PMID: 33813075 DOI: 10.1016/j.wneu.2021.03.128] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/23/2021] [Revised: 03/23/2021] [Accepted: 03/24/2021] [Indexed: 01/11/2023]
Abstract
BACKGROUND Interlaminar endoscopic lumbar discectomy (IELD) is an efficient surgical treatment for lumbar disc herniation. However, this minimally invasive procedure requires a considerable learning curve that has not yet been standardized. This review aimed to evaluate the learning curve's characteristics, including the cutoff point required to achieve technical proficiency and to discuss appropriate training methods. METHODS We systematically searched the core databases (PubMed, Embase, and Cochrane Library) for clinical studies that evaluated the learning curve using quantitative data. We performed a quality assessment using the Newcastle-Ottawa scale. We also compared descriptive statistics, including operative time and other variables before and after the cutoff point. RESULTS Six studies reporting 302 cases of IELD were selected from 7188 screened articles. The cutoff point was randomly set in 3 studies and determined as the curve's asymptote in 3 studies. The mean value for the cutoff point was 22.17 ± 12.40 cases (range: 10-43 cases) and mainly determined based on the operative time, which was shorter in the late group than that in the early group (P < 0.05). The cutoff points were not significant for patient outcome parameters such as pain score, functional result, surgical failure, or complications. CONCLUSIONS The evidence of published studies regarding the learning curve for the IELD technique is insufficient. The reported cutoff points may be significant only for task efficiency. Moreover, they may not represent the asymptote of the curve. Future studies should evaluate the actual plateau points using patient outcome data.

Abstract
Both pain rating and exponential model revealed that percutaneous endoscopic lumbar discectomy provided rapid pain recovery that was maintained for at least 3 months compared with conservative treatments. Lumbar disc herniation (LDH) is a common back disorder that evokes back and/or leg pain. Percutaneous endoscopic lumbar discectomy (PELD) is a minimally invasive surgery for patients with LDH. However, there is little evidence of effectiveness of PELD compared with conservative treatments.

Abstract
OBJECTIVE This meta-analysis was performed to investigate whether percutaneous endoscopic lumbar discectomy (PELD) had a superior effect than other surgeries in the treatment of patients with lumbar disc herniation (LDH). METHOD We searched PubMed, Embase, and Web of Science through February 2018 to identify eligible studies that compared the effects and complications between PELD and other surgical interventions in LDH. The outcomes included success rate, recurrence rate, complication rate, operation time, hospital stay, blood loss, visual analog scale (VAS) score for back pain and leg pain, 12-item Short Form Health Survey (SF12) physical component score, mental component score, Japanese Orthopaedic Association Score, Oswestry Disability Index. A random-effects or fixed-effects model was used to pool the estimate, according to the heterogeneity among the included studies. RESULTS Fourteen studies (involving 2,528 patients) were included in this meta-analysis. Compared with other surgeries, PELD had favorable clinical outcomes for LDH, including shorter operation time (weight mean difference, WMD=-18.14 minutes, 95%CI: -25.24, -11.05; P < .001) and hospital stay (WMD = -2.59 days, 95%CI: -3.87, -1.31; P < .001), less blood loss (WMD = -30.14 ml, 95%CI: -43.16, -17.13; P < .001), and improved SF12- mental component score (WMD = 2.28, 95%CI: 0.50, 4.06; P = .012)) and SF12- physical component score (WMD = 1.04, 95%CI: 0.37, 1.71; P = .02). However, it also was associated with a significantly higher rate of recurrent disc herniation (relative risk [RR] = 1.65, 95%CI: 1.08, 2.52; P = .021). There were no significant differences between the PELD group and other surgical group in terms of success rate (RR = 1.01, 95%CI: 0.97, 1.04; P = .733), complication rate (RR = 0.86, 95%CI: 0.63, 1.18; P = .361), Japanese Orthopaedic Association Score score (WMD = 0.19, 95%CI: -1.90, 2.27; P = .861), visual analog scale score for back pain (WMD = -0.17, 95%CI: -0.55, 0.21; P = .384) and leg pain (WMD = 0.00, 95%CI: -0.10, 0.10; P = .991), and Oswestry Disability Index score (WMD = -0.29, 95%CI: -1.00, 0.43; P = .434). CONCLUSION PELD was associated with better effects and similar complications with other surgeries in LDH. However, it also resulted in a higher recurrence rate. Considering the potential limitations in the present study, further large-scale, well-performed randomized trials are needed to verify our findings.

Nonsurgical treatment outcomes for surgical candidates with lumbar disc herniation: a comprehensive cohort study. Sci Rep 2021; 11:3931. [PMID: 33594185 PMCID: PMC7887235 DOI: 10.1038/s41598-021-83471-y] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/12/2020] [Accepted: 02/01/2021] [Indexed: 11/30/2022] Open
Abstract
Physicians often encounter surgical candidates with lumbar disc herniation (LDH) who request non-surgical management even though surgery is recommended. However, second opinions may differ among doctors. Therefore, a prospective comprehensive cohort study (CCS) was designed to assess outcomes of nonsurgical treatment for surgical candidates who were recommended to undergo surgery for LDH but requested a second opinion. The CCS includes both randomized and observational cohorts, comprising a nonsurgery cohort and surgery cohort, in a parallel fashion. Crossover between the nonsurgery and surgery cohorts was allowed at any time. The present study was an as-treated interim analysis of 128 cases (nonsurgery cohort, n = 71; surgery cohort, n = 57). Patient-reported outcomes included visual analogue scores for the back (VAS-B) and leg (VAS-L), the Oswestry Disability Index, the EuroQol 5-Dimension instrument, and the 36-Item Short-Form Health Survey (SF-36), which were evaluated at baseline and at 1, 3, 6, 12, and 24 months. At baseline, age and SF-36 physical function were significantly lower in the surgery cohort than in the nonsurgery cohort (p < 0.05). All adjusted outcomes significantly improved after both nonsurgical and surgical treatment (p < 0.05). The nonsurgery cohort showed less improvement of VAS-B and VAS-L scores at 1 month (p < 0.01), but no difference between cohorts was observed thereafter for 24 months (p > 0.01). Nonsurgical management may be a negotiable option even for surgical candidates in the shared decision-making process.

Abstract
Transforaminal full-endoscopic spine (TF-FES) surgery is minimally invasive and can be performed under local anesthesia. Thus, it is expected that the patient can return to work (RTW) quickly. However, information in the literature regarding this is sparse. The purpose of this study is to review the timing of RTW after TF-FES surgery. This study involved 50 patients (14 women, 36 men; mean age 44.5 years, age range: 20-65 years) who underwent TF-FES surgery between January 2016 and April 2018. All the patients were active workers. Occupations varied widely (e.g., physician, nurse, helper, clerk, construction worker, chef, and schoolteacher). There were no surgery-related complications. Median time to RTW was 21 days. More than half of the patients could RTW within 21 days. In all, 12 cases (24%) could have RTW within 7 days. Occupations of 12 patients who achieved RTW within 7 days included physician, company owner, and restaurant owner, with 11 in the Light work, 1 was in the Medium work, and none in the Heavy work. All 12 had a quick RTW because their work was Light and they could not take prolonged sick leave. Prompt RTW is possible with TF-FES surgery. The biggest merit of TF-FES surgery is minimal invasiveness to the muscles of the back. Also, it can be performed under local anesthesia. Our findings reveal quicker RTW after surgery, depending on occupational type.

Follow-up results of microendoscopic discectomy compared to day surgery using percutaneous endoscopic lumbar discectomy for the treatment of lumbar disc herniation. BMC Musculoskelet Disord 2021; 22:160. [PMID: 33563264 PMCID: PMC7874495 DOI: 10.1186/s12891-021-04038-6] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/16/2020] [Accepted: 01/21/2021] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Percutaneous endoscopic lumbar discectomy (PELD) is satisfactory for hospitalized patients with lumbar disc herniation (LDH). Currently, only a few studies have reported about the day surgery patients undergoing PELD. METHODS A total of 267 patients with LDH underwent PELD during day surgery and were followed up for at least 3 years. Clinical outcomes were assessed using the visual analog scale (VAS) for leg and lower back pain (VAS-B and VAS-L, respectively) and the Oswestry disability index (ODI). The radiological outcomes, such as lumbar lordosis (LL), sacral slope (SS), the disc-height ratio, and disc instability, were recorded and compared. The clinical effects between patients treated by PELD during day surgery and microendoscopic discectomy (MED) for contemporaneous hospitalized 116 patients with LDH were compared. RESULTS Patients treated by PELD had lower blood loss and shorter hospital stay (P < 0.001) compared to those treated by MED. VAS-L, VAS-B, and ODI decreased significantly after PELD than before the operation and 3 years postoperatively. The postoperative VAS-B in the PELD group was significantly decreased than in the MED group (P = 0.001). The complications rate was 9.4% in the PELD group and 12.1% in the MED group (P = 0.471). The 1-year postoperative recurrence rate in the PELD group was much higher than that in MED group (P = 0.042). The postoperative LL and SS in the PELD group improved significantly compared to the values in the MED group (P < 0.001). According to the disc-height ratio at 3-year follow-up, a significant height loss was observed in the MED group than in the PELD group (P = 0.014). CONCLUSIONS Although the 1-year postoperative recurrence rate was relatively high, the day surgery for LDH undergoing PELD had advantages in terms of less blood loss intraoperatively, short hospital stay, efficacy for back pain, and efficiency to maintain lumbar physiological curvature.

Meta-analysis of the operative treatment of lumbar disc herniation via transforaminal percutaneous endoscopic discectomy versus interlaminar percutaneous endoscopic discectomy in randomized trials. Medicine (Baltimore) 2021; 100:e23193. [PMID: 33592819 PMCID: PMC7870223 DOI: 10.1097/md.0000000000023193] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/12/2019] [Accepted: 10/17/2020] [Indexed: 01/05/2023] Open
Abstract
BACKGROUNDS Transforaminal percutaneous endoscopic discectomy (TF-PELD) and interlaminar percutaneous endoscopic discectomy (IL-PELD) are the most common alternative treatments of lumbar disc herniation. The aim of this study was to compare the operation time duration and X-ray exposure as well as outcomes of TF-PELD and IL-PELD as indicated by the published clinical evidences within randomized trials. METHODS We included randomized, controlled studies reporting operation duration and X-ray exposure as well as clinical outcome evaluations, comparing TF-PELD to IL-PELD with a minimum of 10 patients per group. The included data measures were operation duration, X-ray exposure and postoperation evaluations. Data were synthesized and analyzed using ReviewManager version 5.3. Publication bias was evaluated via funnel plot. The Cochran Q test and the degree of inconsistency (I2) were used to assess heterogeneity. Lowly biased and heterogenous dichotomous data were calculated by odds ratio and continuous data were calculated by mean difference (MD) with 95% confidence intervals (CI). RESULTS Thirteen studies published from January 1970 to March 2018, with a total of 770 lumbar disc herniation patients, including 361 cases of TF-PELD and 409 cases of IL-PELD, were finally included. Meta-analysis of data extracted from these studies revealed that the postoperation outcomes of both surgery methods did not differ significantly, but the surgery duration was significantly shorter in the IL-PELD group than in the TF-PELD group (MD 21.69; 95% CI 12.94-30.27; P = .00001), and the fluoroscopy times demanded in the IL-PELD group was significantly fewer than those in the TF-PELD group (MD 7.57; 95% CI 6.22-8.93; P = .00001). CONCLUSION The main finding of the study is that IL-PELD approach can decrease radiation exposure as their demanded duration of operation and fluoroscopy times were significantly shorter and fewer in the IL-PELD group, which they achieve similar outcomes comparing to TF-PELD. The study is limited at a lack of samples with lumbar disc herniation levels out of L5/S1. The findings implicate selection of IL-PELD approach over TF-PELD at applicable circumstances for lower lumbar disc herniation. Physicians should consider this data when choosing between TF-PELD and IL-PELD.
