Abstract
STUDY DESIGN A single-centre retrospective study of prospectively collected data. OBJECTIVE Analyse factors associated with the patient-reported outcome after far lateral decompression surgery (FLDS) for lumbar nerve root compression using the far-lateral approach. SUMMARY OF BACKGROUND DATA To date, no studies have investigated the influence of vertebral level, coronal segmental Cobb angle, and the nature of the compressive tissue (hard or soft) on the patient-reported outcome following FLDS. PATIENTS AND METHODS Patients who had undergone FLDS between 2005 and 2020 were included. Coronal segmental angle (CSCA) was measured on preoperative, posteroanterior radiographs. The primary outcome measure was the core outcome measures index (COMI) score at two years' follow-up (2Y-FU). Patients who had undergone microsurgical decompression using a midline approach served as a comparator group. RESULTS There were 148 FLDS and 463 midline approach patients. In both groups, there was a significant improvement in the COMI score from preoperative to 2Y-FU ( P <0.0001), with greater improvement in patients treated at higher vertebral levels than in those treated at L5/S1 ( P =0.014). Baseline COMI, American Society of Anesthesiologists grade, body mass index, and low back pain as the "chief complaint" all had a significant association with the two-year COMI score. The nature of compressive tissue showed no association with the COMI score at 2Y-FU. In the FLDS group, there was a statistically significant correlation between the preoperative CSCA and the change in COMI score preoperatively to 2Y-FU ( P <0.001). The association was retained in the multiple regression analysis, controlling for confounders. A one-degree increase in CSCA was associated with a 0.35-point worse COMI score at 2Y-FU ( P =0.003). CONCLUSION Treatment of far lateral nerve root compression showed an overall good patient-reported outcome, but with less improvement with advanced CSCA. Modified approaches and techniques might be preferable for levels L5/S1.

Heliyon 2024; 10:e33503. [PMID: 39071675 PMCID: PMC11283102 DOI: 10.1016/j.heliyon.2024.e33503] [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: 04/05/2024] [Revised: 06/12/2024] [Accepted: 06/21/2024] [Indexed: 07/30/2024] Open
Abstract
Background It is widely believed that the Percutaneous endoscopic lumbar discectomy (PELD) is associated with minimal blood loss. However, significant perioperative hidden blood loss (HBL) is frequently unaccounted for. This study aimed to investigate HBL and peri-operative factors contributing to HBL in a series of individuals undergoing PELD. Method ology: A total of 156 consecutive patients with a mean age of 43.6 years (ranging from 18 to 80 years) who underwent PELD at our department from May 2019 to November 2020, were included in the study. Factors including gender, age, body mass index, symptom duration, operation approach/technique, operation duration, the presence of associated chronic diseases, and improvements in the Visual Analog Scale (VAS) score, Japanese Orthopaedic Association (JOA) score and the Oswestry Disability Index (ODI) were analyzed, and Gross's formula was applied to calculate blood loss, which was used to determine HBL. Results The average total blood loss (TBL) was 221.0 ± 126.2 mL, while the average HBL was 181.7 ± 119.0 mL (82.2 % of TBL). There was no statistically significant difference in HBL between the transverse surgical approach and the interlayer approach. Additionally, no significant differences were observed in improvements in VAS, JOA, and ODI scores between the two surgical approaches. However, the multivariate linear regression analysis revealed that longer surgical time and foraminal decompression were factors contributing to the increase in HBL, which subsequently led to the occurrence of post-operative anemia. Conclusion HBL is significant in PELD cases with long surgical time and lumbar foraminal decompression.

Abstract
BACKGROUND We compare the differences in the efficacy of percutaneous transforaminal endoscopic diskectomy (PTED) between the younger (age <60 years) and older (age ≥60 years) patients with lumbar disk herniation (LDH). METHODS From December 2016 to December 2017, 128 patients with symptomatic LDH underwent PTED and were followed up. Forty-four 60 years old and above, including 19 males and 25 females with an average age of 68.7 (61-82) years, were classified as the elderly age group. Eighty-four patients younger than 60 years were classified as the young age group, which included 48 males and 36 females with an average age of 44.7 (16-58) years. The visual analog scale (VAS) scores, Japanese Orthopaedic Association (JOA) scores, and satisfaction rates of the two groups before and after surgery were compared. RESULTS The operation was completed successfully in both groups. The average follow-up times of the elderly and young age groups were 18.47 ± 2.62 (12-23) and 17.90 ± 3.27 (12-23) months, respectively. One patient in the young age group had recurrence 7 months after surgery, and the symptoms were relieved after PTED was performed again. Two patients with nerve root injury after surgery in the young age group completely recovered after 2 months of conservative treatment. There were no significant surgical complications in the elderly age group. There was no significant difference in postoperative VAS, JOA, and MacNab scores between the two groups. The MacNab scores in the elderly age group were excellent for 28 patients, good for 10 patients, and fair for 6 patients; the satisfaction rate was 86.3%. In the young age group, scores were excellent for 63 patients, good for 14 patients, fair for 5 patients, and poor for 2 patients; the satisfaction rate was 91.7%. CONCLUSION The clinical effectiveness of PTED for treatment of LDH in both elderly and young patients is satisfactory. Age is not a predictor of poor outcomes of PTED.

Clinical Consequences of Incidental Durotomy during Full-Endoscopic Lumbar Decompression Surgery in Relation to Intraoperative Epidural Pressure Measurements. J Pers Med 2023; 13:jpm13030381. [PMID: 36983563 PMCID: PMC10052087 DOI: 10.3390/jpm13030381] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/27/2023] [Revised: 02/12/2023] [Accepted: 02/13/2023] [Indexed: 02/25/2023] Open
Abstract
Background: Seizures, neurological deficits, bradycardia, and, in the worst cases, cardiac arrest may occur following incidental durotomy during routine lumbar endoscopy. Therefore, we set out to measure the intraoperative epidural pressure during lumbar endoscopic decompression surgery. Methods: We conducted a retrospective observational cohort study to obtain intraoperative epidural measurements with an epidural catheter-pressure transducer assembly through the spinal endoscope on 15 patients who underwent lumbar endoscopic decompression of symptomatic lumbar herniated discs and spinal stenosis. The endoscopic interlaminar technique was employed. Results: There were six (40.0%) female and nine (60.0%) male patients aged 49.0667 ± 11.31034, ranging from 36 to 72 years, with an average follow-up of 35.15 ± 12.48 months. Three of the fifteen patients had seizures with durotomy and one of these three had intracranial air on their postoperative brain CT. Another patient developed spinal headaches and diplopia on postoperative day one when her deteriorating neurological function was investigated with a brain computed tomography (CT) scan, showing an intraventricular hemorrhage consistent with a Fisher Grade IV subarachnoid hemorrhage. A CT angiogram did not show any abnormalities. Pressure recordings in the epidural space in nine patients ranged from 20 to 29 mm Hg with a mean of 24.33 mm Hg. Conclusion: Most incidental durotomies encountered during lumbar interlaminar endoscopy can be managed without formal repair and supportive care measures. The intradural spread of irrigation fluid and intraoperatively used drugs and air entrapment through an unrecognized durotomy should be suspected if patients deteriorate in the recovery room. Ascending paralysis may cause nausea, vomiting, upper and lower motor neuron symptoms, cranial nerve palsies, hypotension, bradycardia, and respiratory and cardiac arrest. The recovery team should be prepared to manage these complications.

Comparison of Unilateral Biportal Endoscopic Discectomy with Other Surgical Technics: A Systemic Review of Indications and Outcomes of Unilateral Biportal Endoscopic Discectomy from the Current Literature. World Neurosurg 2022; 168:349-358. [PMID: 36527214 DOI: 10.1016/j.wneu.2022.06.153] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/08/2022] [Revised: 06/29/2022] [Accepted: 06/30/2022] [Indexed: 12/15/2022]
Abstract
OBJECTIVE Unilateral biportal endoscopic (UBE) spine surgery for spinal diseases has been increasing in popularity because of its favorable outcomes. The goal of this systemic review is to analyze the status of outcomes and complications in lumbar disc herniation during UBE discectomy. METHODS A comprehensive search of the PubMed, Embase, Web of Science, and OVID databases published until June 30, 2021, was performed. The outcomes of interest were indications, operative time, blood loss, hospital stay, complications, visual analog scale score, and Oswestry Disability Index. RESULTS Seven studies were included in our research. UBE surgery for lumbar stenosis was excluded. A total of 230 patients with lumbar disc herniation were enrolled in the 7 selected studies. The mean operative time was 74.4 minutes, and the mean length of hospital stay was 4.5 days. Mean incidence of complications reported in the 7 articles was 6.2%. UBE showed shorter hospital stays than did microdiscectomy, no significant differences of Oswestry Disability Index or visual analog scale scores, and good recovery rate among other discectomy techniques (microdiscectomy, full endoscopic transforaminal endoscopic lumbar discectomy, and interlaminar endoscopic lumbar discectomy) at 1 month follow-up. CONCLUSIONS Even with the small number of studies and reports analyzed, biases were the main limitation of this analysis; overall, the clinical outcomes and complication rates associated with UBE discectomy were relatively good. It is clear that UBE discectomy is a good treatment choice for lumbar disc herniation, but to prevent unique UBE surgery complications, a clear understanding of the surgical procedures and careful efforts to overcome the learning curve are necessary.

Abstract
PURPOSE In this work, a modification of the percutaneous surgical approach for removing the lumbar foraminal disc prolapse is introduced. MATERIAL AND METHODS A prospective study was performed. The indication for surgery was foraminal disc prolapse presenting with acute motor or persistent sensory radiculopathy. MRI and X-ray of the lumbar spine were performed. VAS and ODI were recorded. The operation was done under general anesthesia. A needle was inserted for level-localization using C-arm. A 1.5 cm para-median skin incision was performed. A gradual dilatation using trocars was followed by the insertion of a tubular system. Under direct vision using the operative microscope, the lateral edge of the lamina was identified. A small, hooked probe was inserted in the foramen, and its position was documented fluoroscopically. With the help of the microscope, the triad consisting of Pedicle, Nerve root, and Prolapse "PNP" was identified. The nerve root was mobilized, and the prolapsed disc was removed. RESULTS The study included 50 patients, 26 females, and 24 males. The mean follow-up was 18 months. The mean operative time was 65 min. The mean blood loss was 105 ml. The mean VAS improved from 7.8 ± 2.3 preoperatively to 0.8 ± 0.3 after one year (p = 0.001). Mean ODI improved from 28 ± 10.4 to 4 ± 2.3 after one year (p = 0.02). A recurrent disc occurred in 2 patients and was revised in the same technique. CONCLUSION EL-MAPN represents a minimally invasive approach for foraminal disc prolapse removal under direct visual control avoiding injury to the facet joint or pars interarticularis.

Abstract
OBJECTIVE To examine the clinical outcomes of a percutaneous lumbar transforaminal endoscopic discectomy (PTED) with intraoperative computed tomography (iCT) navigation for the treatment of L5-S1 far-lateral lumbar disc herniation (LDH). METHODS A total of 30 patients with L5-S1 far-lateral LDH who underwent PTED with iCT navigation from September 2016 to October 2020 were enrolled in this study. Outcomes were assessed using the visual analog scale pain score, the Oswestry Disability Index, the Japanese Orthopedic Association score, the EQ-5D-5 L and the modified Macnab criteria. Preoperative and postoperative complications were recorded. RESULTS The mean visual analog scale score for leg pain improved from 8.1 at baseline to 2.3, 0.9, 0.7 and 0.9 at 1 day, 1 week, 6 months, and 12 months postoperatively, respectively (P < 0.01). The mean Oswestry Disability Index improved from 78.1% at baseline to 45.5%, 21.9%, 12.6%, and 11.7% at 1 week, 1 month, 6 months, and 12 months postoperatively, respectively (P < 0.01); and the mean Japanese Orthopedic Association score improved from 8.6 at baseline to 14.2, 20.2, 24.4, and 25.6 at 1 day, 1 week, 6 months, and 12 months postoperatively, respectively (P < 0.01). At 12 months postoperatively, the EQ-5D-5 L value significantly increased, from -0.061 ± 0.138 to 0.903 ± 0.064. The rate of a good or excellent modified Macnab result was 93% (26/28) at 12 months postoperatively. In the present study, combined L5-S1 foraminal stenosis tended to lead poor outcomes, which required more postsurgical treatments. CONCLUSIONS With iCT navigation, PTED is a feasible and effective minimally invasive surgery for L5-S1 far-lateral LDH.

Abstract
Background We adopted full-endoscopic lumbar discectomy (FELD) in 2019 with the assistance of the Japanese Society for Minimally Invasive and Endoscopic Techniques of Spinal Neurosurgery (JASMETS). This study analyzed short-term outcomes in our initial FELD cases and compared them with microdiscectomy cases performed during the same period.
Methods FELD was performed in 21 patients over a period of 2 years and 6 months (15 men and 6 women; mean age, 57.0±17.0 years). The transforaminal approach was performed in 8 patients, the posterolateral approach in 3, and the interlaminar approach in 10. During the same period, microdiscectomy was performed in 30 patients. Japanese Orthopaedic Association (JOA) and visual analog scale (VAS) scores, operation time, blood loss volume, complications, and incidence of lumbar disc herniation recurrence were compared between the groups.
Results Preoperative VAS and JOA scores did not significantly differ between the FELD and microdiscectomy groups. JOA and VAS scores significantly improved in both groups after surgery. Operation time and incidence of recurrence rate did not differ.
Conclusion Spine surgeons who adopt FELD can achieve good surgical outcomes similar to those of microdiscectomy, even in the early period. Participation in JASMETS seminars and training and proctoring by a certified endoscopic spine surgeon were instrumental in our experience.

[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.

Abstract
Endoscopic spine surgery is a burgeoning component of the minimally invasive spine surgeon’s armamentarium. The goals of minimally invasive, and likewise endoscopic, spine surgery include providing equivalent or better patient outcomes compared to conventional open surgery, while minimizing soft tissue disruption, blood loss, postoperative pain, recovery time, and time to return to normal activities. A multitude of indications for the utilization of endoscopy throughout the spinal axis now exist, with applications for both decompression as well as interbody fusion. That being said, spinal endoscopy requires many spine surgeons to learn a completely new skill set and the associated learning curve may be substantial. Fluoroscopy is most common imaging modality used in endoscopic spine surgery for the localization of spinal pathology and endoscopic access. Recently, the use of navigation has been reported to be effective, with preliminary data supporting decreased operative times and radiation exposure, as well as providing for improvements in the associated learning curve. A further development is the recent interest in combining robotic guidance with spinal endoscopy, particularly with respect to endoscopic-assisted lumbar fusion. While there is currently a paucity of literature evaluating these image modalities, they are gaining traction, and future research and innovation will likely focus on these new technologies.

A matched comparison of outcomes between percutaneous endoscopic lumbar discectomy and open lumbar microdiscectomy for the treatment of lumbar disc herniation: a 2-year retrospective cohort study. Spine J 2021; 21:114-121. [PMID: 32683107 DOI: 10.1016/j.spinee.2020.07.005] [Citation(s) in RCA: 34] [Impact Index Per Article: 11.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/19/2020] [Revised: 07/12/2020] [Accepted: 07/13/2020] [Indexed: 02/03/2023]
Abstract
BACKGROUND CONTEXT Although open lumbar microdiscectomy (OLMD) is considered to be the gold standard method for discectomy, recent progress in endoscopic spinal surgery has increased the popularity of percutaneous endoscopic lumbar discectomy (PELD) for this indication. However, one of the main drawbacks of PELD is incomplete decompression, especially at the start of the surgeon's learning curve. The functional outcomes of PELD and OLMD in patients matched for age, hernia level, and hernia location have not previously been compared. PURPOSE To compare OLMD with PELD in terms of the clinical outcome and the time to recovery. STUDY DESIGN Retrospective, matched cohort study. PATIENT SAMPLE Data of all patients who underwent elective spinal surgery between January 2015 and June 2017 were extracted from the local database. OUTCOME MEASURES Clinical outcomes were assessed using a 0-to-10 visual analogue scale (VAS) for lower back pain (LBP) and leg pain were scored before surgery and at postoperative day 1 and at each follow-up visit (3, 12, and 24 months), the Oswestry Disability Index (ODI: 0%-100%), the length of hospital stay, time to resumption of work, recurrence of Lumbar disc herniation, procedure failures, and complications. METHODS The participants were matched for age, disc level, and location of the herniated disk (central and paracentral vs. far-lateral). The participants' mean±standard deviation age was 47.09±12.55 (range: 28-70). We compared the various clinical outcomes between the two groups to identify which procedure had better immediate and long-term functional outcomes. The differences in mortality and occurrence of postoperative complications were also compared in patients with PELD versus controls. RESULTS Fifty-eight patients were enrolled (29 with PELD and 29 with OLMD). Both groups reported significant reductions in LBP and leg pain (p<0.01) postoperatively and an improvement in the ODI at 24 months postsurgery. The intergroup difference in the VAS for LBP at 1 day and 3 months was statistically significant (1.48 vs. 3.5, and 1.62 vs. 2.72, respectively; p=0.01 and 0.026, respectively) but the intergroup difference in the ODI was not. The mean length of hospital stay and the time to resumption of work were significantly shorter in the PELD group than in the OLMD group (2.55 vs. 3.21 days, and 4.45 vs. 6.62 weeks, respectively; p=0.037 and 0.01, respectively. There were no significant intergroup differences in terms of complications, recurrence, or procedure failures. CONCLUSIONS Both PELD and OLMD can provide equivalent, satisfactory outcomes. However, PELD demonstrated several potential advantages, including more rapid recovery and lower LBP early on. Further large-scale, randomized studies with long-term follow-up are now warranted.

World Neurosurg 2020; 146:e413-e418. [PMID: 33353758 DOI: 10.1016/j.wneu.2020.10.105] [Citation(s) in RCA: 14] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/30/2020] [Revised: 10/19/2020] [Accepted: 10/20/2020] [Indexed: 11/28/2022]
Abstract
OBJECTIVE This study is a retrospective evaluation of patients with L4-5 highly down-migrated lumbar disc herniation (LDH) operated with interlaminar endoscopic lumbar discectomy (IELD) versus transforaminal endoscopic lumbar discectomy (TELD). METHODS From January 2015 to December 2018, 77 patients with L4-5 highly down-migrated LDH were divided into 2 groups according to different surgical approaches. There were 40 patients who underwent IELD, and 37 patients who underwent TELD. The operation time, hospital stay, Oswestry Disability Index, clinical outcome according with modified MacNab criteria, Visual Analog Scale (VAS) scores, and complications were compared between the IELD and TELD groups. RESULTS Seventy-seven patients were included, 40 and 37 patients underwent IELD and TELD, respectively. The IELD and TELD groups both achieved a significant improvement in Oswestry Disability Index, back and leg VAS scores, and clinical outcome postoperation. Mean operating and x-ray times during operation were significantly shorter in the IELD group than in the TELD group (41.8 vs. 50.3, 1.8 vs. 13.7). There were 3 patients who experienced recurrence in the IELD group and 2 in the TELD group. In the TELD group, there were 3 patients who required revision surgery due to incompletely removed disc fragment. All patients in the IELD group were treated successfully. There was no other complication in these cases. CONCLUSIONS Both IELD and TELD could be a good alternative option for highly down-migrated LDH in L4-L5. IELD may have advantages in operation time and x-ray times during operation compared with TELD.

Ju CI. Technical Considerations of the Transforaminal Approach for Lumbar Disk Herniation. World Neurosurg 2020; 145:597-611. [PMID: 32916343 DOI: 10.1016/j.wneu.2020.08.229] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/22/2020] [Revised: 08/30/2020] [Accepted: 08/31/2020] [Indexed: 11/16/2022]
Abstract
Transforaminal full endoscopic lumbar diskectomy (TELD) is a typical minimally invasive surgery, with the associated benefit of decreased possibility of anatomic structural injury, and is an effective alternative to open diskectomy. Among the various endoscopic spinal surgical techniques currently available, TELD is the most basic and traditional surgery that can be performed through the transforaminal route; it has been used for >30 years. Recently, with the advancements in surgical techniques, TELD has been successfully performed for patients with lumbar disk herniation of different types. However, beginner surgeons are unfamiliar with the anatomy of transforaminal endoscopic surgery and this surgery has a steep learning curve to date. If not well prepared, operators may experience complications that require reoperation in the early stages. These complications may include symptomatic incomplete decompression, exiting nerve root injury, dural tearing, and rarely, hematoma, infection, and visceral injury. Here, we propose several technical guidelines for TELD to increase the possibility of successful lumbar diskectomy and to reduce the incidence of complications. The first step is the accurate anatomic understanding of Kambin triangle and determining the appropriate endoscopic access angle, depending on the type of disk herniation. The second step is to determine a safe and easily accessible entry point and then landing and docking the working sleeve as close to the target as possible without causing exiting nerve root injury. The third step is complete decompression of the symptomatic nerve with free mobilization of the neural tissue. The final step involves performing foraminoplasty using an advanced technique to overcome the limitations associated with TELD in difficult cases.

Abstract
Spine surgery has evolved over centuries from first being practiced with Hippocratic boards and ladders to now being able to treat spinal pathologies with minimal tissue invasion. With the advent of new imaging and surgical technologies, spine surgeries can now be performed minimally invasively with smaller incisions, less blood loss, quicker return to daily activities, and increased visualization. Modern minimally invasive procedures include percutaneous pedicle screw fixation techniques and minimally invasive lateral approach for lumbar interbody fusion (i.e., minimally invasive transforaminal lumbar interbody fusion, extreme lateral interbody fusion, oblique lateral interbody fusion) and midline lumbar fusion with cortical bone trajectory screws. Just as evolutions in surgical techniques have helped revolutionize the field of spine surgery, imaging technologies have also contributed significantly. The advent of computer image guidance has allowed spine surgeons to advance their ability to refine surgical techniques, increase the accuracy of spinal hardware placement, and reduce radiation exposure to the operating room staff. As the field of spine surgery looks to the future, many novel technologies are on the horizon, including robotic spine surgery, artificial intelligence, and machine learning to help improve preoperative planning, improve surgical execution, and optimize patient selection to ensure improved postoperative outcomes and patient satisfaction. As more spine surgeons begin incorporating these novel minimally invasive techniques into practice, the field of minimally invasive spine surgery will continue to innovate and evolve over the coming years.

Abstract
Background Transforaminal endoscopic discectomy was popular in the treatment of lumbar disc herniation. Previous study focuses on the leg pain of disc herniation, and little study concern the residual leg numbness after surgery. The purposes of this study were to evaluate the clinical outcomes of transforaminal endoscopic discectomy in the treatment of lumbar disc herniation with leg pain and numbness. Methods Patients with one level lumbar disc herniation who had transforaminal endoscopic lumbar discectomy from June 2016 to July 2019 were categorized into two groups according to the leg numbness. 293 patients initially fulfilled the study criteria, and 27 patients were lost to follow-up. Of the remaining 266 patients available for analysis, 81 cases with leg numbness and pain (A group), and 185 cases with leg pain (B). Endoscopic transforaminal lumbar discectomy was performed, and the clinical outcomes of blood loss, operation times, hospital stay days, pain (Visual Analog Scale, VAS-pain), numbness (VAS-numbness), functional disability (Oswestry Disability Index, ODI), and the disk height and intervertebral foramen height were recorded. Results All patients with pain and numbness pre-operation in group A, complain of leg numbness during or just after walking or standing not diminished after surgery in group A, and no one complain numbness after surgery in group B. The pain index and ODI score were better than preoperational in all patients (P < 0.01), and no significant difference between two groups (P > 0.05). The postoperative disk and foramen height were no significant difference compare to preoperative in all patients (P > 0.05), and no significant difference between two groups (P > 0.05). The leg numbness symptoms last longer in central disc herniation patients (10.4 ± 2.2 months) than in paracentral (6.3 ± 2.1 months) and foraminal disc herniation patients (5.6 ± 2.3 months) after surgery (P < 0.01). Conclusions Based on the results of this study, transforaminal endoscopic lumbar discectomy was effective and safe procedures in the treatment of disc herniation with leg pain and numbness. The leg numbness symptoms last longer in central disc herniation patients than in paracentral and foraminal disc herniation patients after surgery.

Abstract
STUDY DESIGN A prospective randomized controlled study. OBJECTIVE To clarify whether percutaneous transforaminal endoscopic discectomy (PTED) has better clinical outcomes and less surgical trauma compared with microendoscopic discectomy (MED). SUMMARY OF BACKGROUND DATA Two kinds of minimally invasive spine surgeries, PTED and MED, are now widely used for the treatment of lumbar disc herniation (LDH). It is still a controversial issue to choose the proper surgical approach. METHODS In this single-center, open-label, randomized controlled trial, patients were included if they had persistent signs and symptoms of radiculopathy with corresponding imaging-confirmed LDH, and were randomly allocated to PTED or MED group. The primary outcome was the score of Oswestry Disability Index (ODI) and the secondary outcomes included the score of Medical Outcomes Study 36-Item Short-Form Health Survey bodily pain and physical function scales, European Quality of Life-5 Dimensions, and Visual Analogue Scales for back pain and leg pain. RESULTS A total of 250 participants were randomly assigned to two treatment groups, 241 of that received the specific surgical procedure. Two hundred twenty-two patients (92.1%) have completed the 2-year follow-up. Both the primary and secondary outcomes did not differ significantly between the two treatment groups at each prespecified follow-up time (P > 0.05). For PTED, the postoperative improvement of ODI score in the median herniation subgroup was less compared with paramedian subgroup. For MED, less improvement of ODI score was found in far-lateral herniation subgroup compared with paramedian subgroup. Total complication rate over the course of 2 year was 13.44% in PTED group and 15.57% in MED group (P = 0.639). Ten cases (8.40%) in PTED group and five cases (4.10%) in MED group suffered from residue/recurrence of herniation, for which reoperation was required. CONCLUSION Over the 2-year follow-up period, PTED did not show superior clinical outcomes and did not appear to be safer procedure for patients with LDH compared with MED. PTED had inferior results for median disc herniation, whereas MED did not appear to be the best option for far-lateral disc herniation. LEVEL OF EVIDENCE 2.

Abstract
BACKGROUND Bilateral or huge disc herniations cause bilateral radiculopathy and severe lower back pain. In such cases, a bilateral discectomy may be required to resolve the radicular pain in both legs. We attempted a surgical technique involving bilateral lumbar discectomy via a unilateral approach using a percutaneous biportal endoscopic technique. The purpose of the present study was to describe our surgical technique and investigate the clinical outcomes in symptomatic bilateral lumbar disc herniation. METHODS Eleven patients with bilateral disc herniation of the L4-L5 or L5-S1 segments were surgically treated using the percutaneous biportal endoscopic approach. Biportal endoscopic unilateral laminotomy with bilateral discectomy was performed in all patients. Postoperative magnetic resonance imaging was performed 1 day after surgery, and the clinical parameters were investigated preoperatively and postoperatively. RESULTS All enrolled patients were successfully treated by biportal endoscopic bilateral discectomy via a unilateral approach. Surgery was performed at the L4-L5 level in 1 patient and the L5-S1 level in 10 patients. The mean operative time was 67.5 ± 13.1 minutes. A visual analog scale of leg pain and the Oswestry disability index showed significant improvement after surgery (P < 0.05). CONCLUSION Endoscopic unilateral laminotomy with bilateral discectomy using the percutaneous biportal endoscopic approach could be an effective and alternative treatment of symptomatic bilateral herniated disc disease affecting L4-L5 or L5-S1 segments.

Abstract
OBJECTIVE Endoscopic discectomy (ED) has been advocated as a less-invasive alternative to open microdiscectomy (OM) and tubular microdiscectomy (TM) for lumbar disc herniations, with the potential to decrease postoperative pain and shorten recovery times. Large-scale, objective comparisons of outcomes between ED, OM, and TM, however, are lacking. The authors' objective in this study was to conduct a meta-analysis comparing outcomes of ED, OM, and TM. METHODS The PubMed database was searched for articles published as of February 1, 2019, for comparative studies reporting outcomes of some combination of ED, OM, and TM. A meta-analysis of outcome parameters was performed assuming random effects. RESULTS Twenty-six studies describing the outcomes of 2577 patients were included. Estimated blood loss was significantly higher with OM than with both TM (p = 0.01) and ED (p < 0.00001). Length of stay was significantly longer with OM than with ED (p < 0.00001). Return to work time was significantly longer in OM than with ED (p = 0.001). Postoperative leg (p = 0.02) and back (p = 0.01) VAS scores, and Oswestry Disability Index scores (p = 0.006) at latest follow-up were significantly higher for OM than for ED. Serum creatine phosphokinase (p = 0.02) and C-reactive protein (p < 0.00001) levels on postoperative day 1 were significantly higher with OM than with ED. CONCLUSIONS Outcomes of TM and OM for lumbar disc herniations are largely equivalent. While this analysis demonstrated that several clinical variables were significantly improved in patients undergoing ED when compared with OM, the magnitude of many of these differences was small and of uncertain clinical relevance, and several of the included studies were retrospective and subject to a high risk of bias. Further high-quality prospective studies are needed before definitive conclusions can be drawn regarding the comparative efficacy of the various surgical treatments for lumbar disc herniations.

Abstract
Purpose To predict the early recurrence after full endoscopic lumbar discectomy, we analyzed factors related to demographic factor anatomical factors, operative method, and postoperative management, and predicted the possibility of recurrence according to the scoring system. Materials and Methods In this prospective study, we enrolled 300 patients who underwent 1 out of 3 surgical procedures. The patients were randomized into one of the following groups: group A (n = 100), transforaminal inside-out approach; group B (n = 100), transforaminal outside-in approach; and group C (n = 100), interlaminar approach. The clinical results were evaluated by a visual analogue scale (VAS). Related factors evaluated with points of (A) demographic factors: (1) age, (2) gender, (3) BMI, (B) anatomical factors: (4) disc degeneration scale, (5) modic change, (6) number of involved disc herniation, (7) history of discectomy (first, recurred), (8) herniated disc level, (9) disc height, (10) segmental dynamic motion, (11) disc location, (C) operation factors: (12) annulus preservation along the disc protrusion, (13) approach method (transforaminal inside-out, transforaminal outside-in, interlaminar); (D) postoperative care factors: (14) early ambulation, (15) spinal orthosis (corset) application. Among these, we analyzed statistically significant recurrence risk factors after PELD in all patients and early recurrence predicting score ratio was obtained. Results The overall recurrence rate was 9.33%. The recurrence rate was 11%, 10%, and 7% for groups A, B, and C, respectively. Average early recurrence time was 3.26 months. The change in preoperative and postoperative VAS score was from 8.07 to 1.39, 8.34 to 1.34, and 8.14 to 1.86 in groups A, B, and C, respectively. The recurrence rate based on the (1) age was <40 years: 5.22% (6/115), 41–60 years: 16.1% (20/124), and >61 years: 3.07% (2/65); (2) gender was male: 13/139 (9.35%), female: 15/161 (9.32%); (3) BMI was obese: 17.57% (13/74), overweight: 11.6% (9/77), underweight: 6.35% (4/63), and normal weight: 2.33% (2/86); (4) degeneration scale was grades 1–2: 2% (1/50), grade 3: 7.4% (10/135), and grades 4–5: 14.8% (17/115); (5) modic change was type I: 25% (3/12), type II: 14.3% (1/7), type III: 33% (1/3), and no modic change: 8.27% (23/278); (6) number of involved disc herniation was 1 level: 3.9% (5/128), 2 level: 10.4% (13/125), 3 levels: 18.9% (7/37), and 4 levels: 30% (3/10); (7) history of discectomy was first: 8.83% (25/283) and repeated: 17.65% (3/17); (8) herniated disc level was L1–L2/L2–L3/L3–L4: 3.95% (3/76) and L4–L5: 14.6% (18/123); (9) disc height was <80%: 17.14% (6/35), 81%–100%: 8.16% (12/147), and >101%: 8.5% (10/118); (10) segmental dynamic motion was 1–10°: 8.58% (20/233) and 11–20° : 11.9% (8/67); (11) disc location was central: 7.41% (2/27), foraminal: 3.03% (2/66), and inferior/superior/paracentral: 11.59% (24/207); (12) radical annulotomy was 8.05% (7/87) vs. 9.86% (21/213); (13) approach method was transforaminal (inside-out): 11% (11/100), transforaminal (outside-in): 10% (10/100), and interlaminar: 7% (7/100); (14) early ambulation was 16.42% (23/140) vs. 3.13% (5/160); and (15) spinal orthosis application was 7.35% (10/136) vs. 10.98% (18/164). According to the above results, after summation of all scores, the early recurrence predicting score: recurrence rate ratio was 1–4: 0% (0/23), 5–8: 7.1% (13/183), 9–12: 8% (6/75) and 13–16 100% (10/10). Conclusions Early recurrence after PELD is associated with several risk factors such as BMI, degeneration scale, combined HNP, and early ambulation. If we use the predicting score, we can postulate the occurrence of early recurrence after PELD. Knowing the predictive factors prior to surgical intervention will allow us to decrease the early recurrence rate after PELD.

Abstract
To examine the clinical results of different minimally invasive techniques for the therapy of far lateral disc herniation in middle-aged and elderly patients. An endoscopic approach (percutaneous endoscopic lumbar discectomy; PELD), MIS-TLIF combined with contralateral translaminar screw (MIS-TLIF CTS), and MIS-TLIF combined with bilateral pedicle screws (MIS-TLIF BPS) were evaluated via a retrospective chart review. Data from 74 consecutive middle-aged and elderly patients with far lateral disc herniation were analyzed. All patients underwent surgery; 19 with PELD, 24 with MIS-TLIF CTS, and 31 with MIS-TLIF BPS. Clinical data included the length of the incision, duration of the operation, estimated blood loss, hospitalization time, operation cost, recurrence rate, and fusion rate. Preoperative and postoperative patient outcomes including the VAS, ODI scores and MacNab criteria were assessed and recorded. The mean follow-up time was 26.4 months (range from 14 to 46 months). Compared with the internal fixation groups, the length of the incision, duration of operation, estimated blood loss, and hospitalization time were obviously lower in the PELD group. The difference in operation cost among the three methods was statistically significant. The postoperative VAS scores for LBP and LP decreased significantly as compared with those recorded preoperatively. The postoperative ODI scores were lower than those recorded preoperatively. MacNab criteria rating excellent, good and fair results were in 27, 37 and 10 patients, respectively. Conclusion: PELD, MIS-TLIF CTS, and MIS-TLIF BPS are all effective minimally invasive techniques for the therapy of single segment far lateral lumbar disc herniation in middle-aged and elderly patients. PELD had a shorter operation time and less surgical trauma, being a less invasive and more economical method; however, there was no recurrence of disc herniation after fixation. Compared with MIS-TLIF BPS, MIS-TLIF CTS obtained a similar clinical effect and certain costs were saved.

Abstract
Objective To evaluate the clinical outcome of reoperation after percutaneous endoscopic lumbar discectomy (PELD) as compared with primary spinal decompression and fusion. Methods A retrospective study from December 2014 to December 2017 was conducted at Peking Union Medical College Hospital and comprised 39 patients with symptomatic lumbar degenerative disease (LDD): 13 post‐PELD who underwent reoperation (revision surgery group) and 26 who received primary spinal decompression and fusion (primary open surgery group). The two groups were compared regarding: operative time, blood loss, transfusion, hospitalization, postoperative visual analog scale (VAS) scores, Oswestry Disability Index (ODI) scores, Japanese Orthopedic Association (JOA) improvement rate, and postoperative complications. The Mann–Whitney U‐test was applied to analyze continuous parameters, and the χ2‐test for categorical parameters. Fisher's exact test was used for small data subsets. Results There was no statistically significant difference between the two groups in mean age (52.7 years vs 52.9 years), gender ratio (6 men‐to‐7 women vs 12 men‐to‐14 women), body mass index, medical history, preoperative diagnosis, or surgical spine level (P > 0.05). The mean operative time of the revision surgery group was significantly longer than that of the primary open surgery group (160.0 min vs 130.2 min, P < 0.05). The revision surgery group also had a significantly higher mean estimated blood loss, postoperative drainage, and length of hospital stay (P < 0.05). However, no significant differences were found between the two groups in terms of hemoglobin and hematocrit values, preoperatively and postoperatively. The rate of transitional neurological irritation was higher in the revision surgery group (61.5% vs 3.8%; P < 0.05), as was intraoperative durotomy and cerebrospinal fluid leakage (30.8% vs 3.8%, P < 0.05). At 1 month, the VAS and ODI scores of the primary open surgery group were significantly better than those of the revision surgery group, while the improvement in JOA scores was similar. After 6 and 12 months’ follow‐up, the VAS and ODI scores and the rates of JOA improvement were comparable. Conclusion Patients with LDD who received primary spinal decompression and fusion experienced lower rates of perioperative complications and shorter hospitalization compared with patients who underwent revision surgery after PELD, but the clinical outcomes at the last follow‐up of both groups were satisfactory.

Abstract
OBJECTIVE To investigate the efficacy and safety of percutaneous transforaminal endoscopic discectomy (PTED) in the treatment of lumbar spinal stenosis (LSS) combined with osteoporosis. METHODS Eighty patients with LSS combined with osteoporosis were divided into a control and PTED group, which received conventional transforaminal lumbar interbody fusion and PTED, respectively. The surgical indications, incision visual analogue scale (VAS), lumbar and leg pain VAS, lumbar Japanese Orthopaedic Association (JOA) and Oswestry disability index (ODI) scores, bone mineral density (BMD), and adverse reactions were observed. RESULTS Compared with the control group, in the PTED group, the operation time, bleeding loss and hospitalization duration, incision VAS scores at postoperative 12, 24 and 48 h and lumbar and leg pain VAS and lumbar ODI scores on postoperative 6 months were significantly decreased (P < 0.01), and the lumbar JOA score on postoperative 6 months was significantly increased (P < 0.05). There was no significant difference in BMD between two groups (P > 0.05). Compared with the control group, in the PTED group, the total effective rate was significantly higher (P < 0.05), and the incidence of adverse reactions was significantly lower (P < 0.05). CONCLUSIONS PTED is safe and effective in the treatment of LSS combined with osteoporosis.

Abstract
Ten years ago, endoscopic techniques began to prevail in clinical treatment of lumbar disc herniation (LDH), but to date, few studies have reported the clinical efficacy of percutaneous transforaminal endoscopic discectomy (PTED) in treating adolescent LDH. This study aimed to evaluate the surgical outcomes of PTED in treating adolescent patients with LDH.Between June 2012 and June 2016, retrospective analysis of 43 adolescent patients diagnosed with single-segment LDH at spine surgery at the Second Affiliated Hospital of Anhui Medical University. The patients' lower limb pain was evaluated using visual analogue scale (VAS) scores and the Oswestry Disability Index (ODI). The VAS is the most commonly-used quantitative method for assessing the degree of pain in clinical practice. The measurement method is to draw a 10 cm horizontal line on a piece of paper, 1 end of which is 0, indicating no pain, while the other end is 10, which means severe pain, and the middle part indicates different degrees of pain. The clinician then asks the patient to make a mark on the line to indicate the degree of pain based on how he or she feels. The ODI is the most widely-used assessment method internationally for lumbar or leg pain at present. The ODI questionnaire is composed of 10 questions, covering pain intensity, independent living, carrying, walking, sitting, standing, sleep, travel, sex, and social life. Every category comprises 6 options, with the highest score for each question being 5 points. Thus the 1st option is worth 0 points, the last option scores 5 points, and higher scores represent more serious dysfunction. Patient satisfaction was evaluated using the modified MacNab score. Clinical outcomes were measured preoperatively, and at 3 days, 6 months, and 12 months postoperatively.All 43 patients were followed up for 12 to 24 months. The average follow-up time was 18.33 months. The VAS scores and ODI scores at 3 days, 6 months, and 12 months postoperatively were significantly lower than before surgery. The difference was statistically significant (P < .001). The differences in VAS scores and ODI scores at 3 days, 6 months, and 12 months after surgery were also statistically significant (P < .001). According to the modified MacNab criteria, 26 cases were rated excellent, 14 cases were good, and 3 cases were acceptable at the final follow-up, and 93.02% of these patients had excellent outcomes.The PTED is an effective and safe surgical method for the treatment of adolescent patients with LDH, but high-quality randomized controlled trials are still required to further verify these findings.

Abstract
Background Since open Wiltse approach allows limited visualization for foraminal stenosis leading to an incomplete decompression, we report the short-term clinical and radiological results of unilateral biportal endoscopic foraminal decompression using 0° or 30° endoscopy with better visualization. Methods We examined 31 patients that underwent surgery for neurological symptoms due to lumbar foraminal stenosis which was refractory to 6 weeks of conservative treatment. All 31 patients underwent unilateral biportal endoscopic far-lateral decompression (UBEFLD). One portal was used for viewing purpose, and the other was for surgical instruments. Unilateral foraminotomy was performed under guidance of 0° or 30° endoscopy. Clinical outcomes were analyzed using the modified Macnab criteria, Oswestry disability index, and visual analogue scale. Plain radiographs obtained preoperatively and 1 year postoperatively were compared to analyze the intervertebral angle (IVA), dynamic IVA, percentage of slip, dynamic percentage of slip (gap between the percentage of slip on flexion and extension views), slip angle, disc height index (DHI), and foraminal height index (FHI). Results The IVA significantly increased from 6.24° ± 4.27° to 6.96° ± 3.58° at 1 year postoperatively (p = 0.306). The dynamic IVA slightly decreased from 6.27° ± 3.12° to 6.04° ± 2.41°, but the difference was not statistically significant (p = 0.375). The percentage of slip was 3.41% ± 5.24% preoperatively and 6.01% ± 1.43% at 1-year follow-up (p = 0.227), showing no significant difference. The preoperative dynamic percentage of slip was 2.90% ± 3.37%; at 1 year postoperatively, it was 3.13% ± 4.11% (p = 0.720), showing no significant difference. The DHI changed from 34.78% ± 9.54% preoperatively to 35.05% ± 8.83% postoperatively, which was not statistically significant (p = 0.837). In addition, the FHI slightly decreased from 55.15% ± 9.45% preoperatively to 54.56% ± 9.86% postoperatively, but the results were not statistically significant (p = 0.705). Conclusions UBEFLD using endoscopy showed a satisfactory clinical outcome after 1-year follow-up and did not induce postoperative segmental spinal instability. It could be a feasible alternative to conventional open decompression or fusion surgery for lumbar foraminal stenosis.

Abstract
The purpose of this retrospective study was to assess the clinical outcomes of discectomy by using full-endoscopic visualization technique via the interlaminar approach versus the transforaminal approach under general anesthesia in the treatment of L5-S1 disc herniation.Sixty patients with L5-S1 disc herniation were non-randomly recruited and assigned into two groups. One group (thirty patients) underwent discectomy by using full-endoscopic visualization technique via the interlaminar approach under general anesthesia, while the other group (thirty patients) underwent discectomy by using full-endoscopic visualization technique via the transforaminal approach under general anesthesia. The operative time, fluoroscopy time, and perioperative complications were recorded. The visual analog scale (VAS) score for leg and back pain and Oswestry disability index (ODI) score were evaluated preoperatively and at 3, 6, and 18 months postoperatively.The mean operative time and fluoroscopy time in the interlaminar group were significantly shorter compared with those in the transforaminal group. The mean VAS and ODI postoperative scores were significantly improved over the preoperative scores in both groups. According to the MacNab classification system, more than 90.0% of the patients achieved an excellence/good rating in both groups. An intraoperative epineurium injury occurred in both groups. The total recurrence rate during 18 months follow-up was 3.3% in the interlaminar group and 0% in the transforaminal group.It is efficient and safe to perform discectomy by using full-endoscopic visualization technique via both interlaminar and transforaminal approaches under general anesthesia in patients with L5-S1 disc herniation. Discectomy performed by using full-endoscopic visualization technique via the interlaminar approach requires a shorter operative time and suffers less radiation exposure than the transforaminal approach.

Abstract
OBJECTIVE To compare the clinical outcomes of patients with lumbar disc herniation with bi-radicular symptoms undergoing percutaneous endoscopic lumbar discectomy (PELD) and minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF). METHODS From January 2008 to January 2016, 89 consecutive patients with lumbar disc herniation with biradicular symptoms were treated with PELD or MIS-TLIF. The data were collected prospectively for analysis including clinical and radiographic results after revision surgery and complications. RESULTS During the follow-up period, the postoperative data between the 2 treatment groups showed no significant difference in the mean total postoperative visual analog score for leg pain and the Japanese Orthopedic Association and Oswestry disability index scores. In the MIS-TLIF group, the recovery rate and satisfaction rate were higher than those in the PELD group, and the difference was statistically significant. The only postoperative factor that was significantly different was postoperative back pain, which was lower in the MIS-TILF group. The other significant differences between the 2 treatment groups were associated with the complications such as intervertebral infection and adjacent segment disease. CONCLUSIONS Both PELD and MIS-TLIF, as treatments for lumbar disc herniation with biradicular symptoms, showed favorable clinical outcomes. Compared with MIS-TLIF, PELD had the following advantages: 1) it is performed under local anesthesia and 2) there is rare possibility of "fusion disease," such as ASD. However, the PELD is also revealed several problems, including a relatively lower success rate and satisfaction, a relative higher rate of postoperative long-term chronic low back pain and the possibility of recurrence, despite the low incidence.

Abstract
This study was performed to describe the extraforaminal approach of biportal endoscopic spinal surgery (BESS) as a new endoscopic technique for transforaminal decompression and discectomy and to demonstrate the clinical outcomes of this new procedure for the first time. Twenty-one patients (27 segments) who underwent the extraforaminal approach of BESS between March 2015 and April 2016 were enrolled according to the inclusion and exclusion criteria. The operative time (minutes/level) and complications after the procedure were recorded. The visual analog scale (VAS) score was checked to assess the degree of radicular leg pain preoperatively and at the time of the last follow-up. The modified Macnab criteria were used to examine the clinical outcomes at the time of the last follow-up. The mean duration of the follow-up period was 14.8 months (minimum duration 12 months). The mean operative time was 96.7 minutes for one level. The mean VAS score for radicular leg pain dropped from a preoperative score of 7.5 ± 0.9 to a final follow-up score of 2.5 ± 1.2 (p < 0.001). The final outcome according to the modified Macnab criteria was excellent in 5 patients (23.8%), good in 12 (57.2%), fair in 4 (19.0%), and poor in 0. Therefore, excellent or good results (a satisfied outcome) were obtained in 80.9% of the patients. Complications were limited to one dural tear (4.8%). The authors found that the extraforaminal approach of BESS was a feasible and advantageous endoscopic technique for the treatment of foraminal lesions, including stenosis and disc herniation. They suggest that this technique represents a useful, alternative, minimally invasive method that can be used to treat lumbar foraminal stenosis and disc herniation.

Abstract
Background In the last decades, full-endoscopic techniques to treat lumbar disc herniation (LDH) have gained popularity in clinical practice. However, few studies have described the safety and efficacy of percutaneous transforaminal endoscopic discectomy (PTED) in treating younger patients with LDH. This study aims to evaluate the preliminary surgical outcome and complication of PTED in treating younger patients with LDH. Methods Between June 2012 and June 2016, 72 young patients (< 45 years old) who underwent PTED for single-level LDH were prospectively followed up. All patients were followed up for at least 12 months (range 12–35 months). Pain was measured using visual analogue scale (VAS) scores. Patient satisfaction was evaluated using the MacNab outcome scale. Clinical outcomes were measured preoperatively, at 2 days and 6 months, and 12 months postoperatively. Results The mean VAS score for back pain was 5.1 ± 2.3 preoperatively and 3.1 ± 1.2, 2.1 ± 0.5, and 2.0 ± 0.7 at 2 days, 6 months, and 12 months postoperatively, respectively. The VAS score for leg pain was 7.1 ± 2.6 preoperatively and 3.0 ± 1.1, 2.1 ± 1.3, and 1.9 ± 0.8 at 2 days, 6 months, and 12 months postoperatively, respectively. These postoperative scores were all significantly different when compared with preoperative scores (P < 0.001). According to the modified MacNab outcome scale, excellent was obtained in 43 patients, good was obtained in 25 patients, and fair was obtained in 4 patients, and 94.44% of these patients had excellent and good outcomes at the final follow-up. There were no complications related to surgery, and no spinal instability was detected. Conclusion PTED appears to be an effective and safe intervention for younger patients with LDH. High-quality randomized controlled trials are required to further study the efficacy and safety of PTED in treating younger patients with LDH.

Abstract
Purpose To evaluate the efficacy of suprapedicular circumferential opening technique (SCOT) of percutaneous endoscopic transforaminal lumbar discectomy (PETLD) for high grade inferiorly migrated lumbar disc herniation. Material and Methods Eighteen consecutive patients who presented with back and leg pain with a single-level high grade inferiorly migrated lumbar disc herniation were included. High grade inferiorly migrated disc was removed by the SCOT through PETLD approach. Outcome evaluation was done with visual analog scale (VAS) and Mac Nab's criteria. Result There were 14 males and 4 females. The mean age of patients was 53.3 ± 14.12 years. One, 4, and 13 patients had disc herniation at L1-2, L3-4, and L4-5 levels, respectively, on MRI, which correlated with clinical findings. The mean follow-up duration was 8.4 ± 4.31 months. According to Mac Nab's criteria, 9 patients (50%) reported excellent and the remaining 9 patients (50%) reported good outcomes. The mean preoperative and postoperative VAS for leg pain were 7.36 ± 0.73 and 1.45 ± 0.60, respectively (p < 0.001). Improvement in outcomes was maintained even at final follow-up. There was no complication. Conclusion In this preliminary study we achieved good to excellent clinical results using the SCOT of PETLD for high grade inferiorly migrated lumbar disc herniation.

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

Abstract
This study investigated the therapeutic effect of percutaneous endoscopic lumbar discectomy on lumbar disc herniation, and explored its effect on oxidative stress in patients with lumbar disc herniation. One hundred and ten patients with lumbar disc herniation were selected in The Affiliated People's Hospital of Shanxi Medical University from May 2015 to May 2016. Patients were divided into control group (n=50) and observation group (n=60) according to different surgical methods. Patients in control group were subjected to traditional open discectomy, while patients in observation group were treated with percutaneous endoscopic lumbar discectomy. Surgical-related indicators, ODI and VAS scores before and 3 months after surgery, serum inflammatory factors and oxidative stress indicators were compared between 2 groups. There was no significant difference in operation time between the groups. Blood loss, incision size and time of bed rest in observation group were better than those in control group (P<0.05). Compared with preoperative levels, ODI and VAS scores of the two groups were significantly reduced at 3 months after surgery, but the scores of observation group were significantly higher than those of control group (P<0.05). There were no significant differences in the levels of serum inflammatory factors TNF-α and CRP and oxidative stress indicators MDA, MPO, SOD and TAC between the two groups before surgery (P>0.05). Levels of serum inflammatory factors TNF-α and CRP and oxidative stress indicators MDA and MPO were significantly lower and levels of oxidative stress indicators SOD and TAC were significantly higher in observation group than in control group (P<0.05). Therefore, treatment of lumbar disc herniation with percutaneous endoscopic lumbar discectomy has the advantages of small trauma, less blood loss and fast recovery, and can effectively improve the dysfunction, reduce pain and serum levels of inflammatory factors, and improve the levels of oxidative stress indicators, thereby improving the surgical results. Thus, this method should be considered for wide-use.

Abstract
Percutaneous endoscopic lumbar foraminotomy (ELF) is a novel minimally invasive technique used to treat lumbar foraminal stenosis. However, the validity of foraminal decompression based on quantitative assessment using magnetic resonance imaging (MRI) has not yet been established. The objective of this study was to investigate the radiographic efficiency of ELF using MRI. Radiographic changes of neuroforamen were measured based on pre- and postoperative MRI findings. Images were blindly analyzed by two observers for foraminal stenosis grade and foraminal dimensions. The intraclass correlation coefficient (ICC) and k statistic were calculated to determine interobserver agreement. Thirty-five patients with 40 neuroforamen were evaluated. The mean visual analog scale (VAS) score improved from 8.4 to 2.1, and the mean Oswestry disability index (ODI) improved from 65.9 to 19.2. Overall, 91.4% of the patients achieved good or excellent outcomes. The mean grade of foraminal stenosis significantly improved from 2.63 to 0.68. There were significant increases in the mean foraminal area (FA) from 50.05 to 92.03 mm2, in mean foraminal height (FH) from 11.36 to 13.47 mm, in mean superior foraminal width (SFW) from 6.43 to 9.27 mm, and in mean middle foraminal width (MFW) from 1.47 to 78 mm (P < 0.001). Interobserver agreements for preoperative and postoperative measurements were good to excellent with the exception of SFW. In conclusion, foraminal dimensions and grades of foraminal stenosis significantly improved after ELF. These findings may enhance the clinical relevance of endoscopic lumbar foraminal decompression.

Abstract
Few neurosurgeons practicing today have had training in the field of endoscopic spine surgery during residency or fellowship. Nevertheless, over the past 40 years individual spine surgeons from around the world have worked to create a subfield of minimally invasive spine surgery that takes the point of visualization away from the surgeon's eye or the lens of a microscope and puts it directly at the point of spine pathology. What follows is an attempt to describe the story of how endoscopic spine surgery developed and to credit some of those who have been the biggest contributors to its development.

Abstract
OBJECTIVE Lumbar foraminal or extraforaminal disc herniations (FEFDH) have unusual clinical features and higher incidence in elderly patients compared to usual intraspinal canal disc herniations. We evaluated the efficacy of microdiscectomy via paramedian approach for lumbar FEFDH in elderly patients over the age of 65. METHODS Retrospective study was performed in 68 patients over the age of 65 (23 male and 45 female patients; 71.46±3.87 years) who underwent microdiscectomy via paramedian approach for unilateral lumbar FEFDH causing sciatica. The radiological factors including degree of slippage, presence of instability, disc height, and degree of disc degeneration; pain and functional status by the means of visual analogue scale score, Oswestry Disability Index score, and Macnab classification were analyzed preoperatively and during the postoperative follow-up period of 3 years to evaluate the efficacy of the surgical treatment. RESULTS Pain and functional status improved according to short- and long-term follow-up evaluations after surgery. Radiological changes following surgery, which can be understood as structural deteriorations and deformations, did not represent patient condition. Nine patients underwent additional surgery due to sustained or recurring leg pain of aggravation of back pain, and fusion surgery was required for 3 patients. Degree of preoperative slippage was the only statistically significant factor related to additional surgery (p<0.05). CONCLUSION Microdiscectomy via paramedian approach for FEFDH may be a good surgical alternative in elderly patients. Radiological changes after surgery did not show a concordance with patients' actual functional status. The excessive preoperative slippage tended to lead to unfavorable result after surgery and was associated with additional surgery.

Abstract
PURPOSE This study reports a new approach for percutaneous endoscopic lumbar iscectomy (PELD), especially for soft, highly down-migrated lumbar disc herniation. METHODS Seven patients with soft, highly down-migrated lumbar disc herniation who underwent PELD via a translaminar approach under local anaesthesia from January 2013 to June 2015, including five patients who underwent failed PELD in other hospitals, were retrospectively analyzed. Clinical outcomes were evaluated according to pre-operative and post-operative visual analogue scale (VAS) scores, Oswestry disability index (ODI) scores and post-operative magnetic resonance imaging (MRI). RESULTS The highly down-migrated lumbar disc herniation was completely removed by PELD via a translaminar approach in seven patients, as confirmed by post-operative MRI. Leg pain was eased after removal of the disc migrations. The mean follow-up duration was 9.8 (range, 6-14) months. The mean pre-operative VAS was 7.6 ± 0.8 (range, 6-9), which decreased to 3.1 ± 1.5 (range, 2-5) at one week post-operatively and to 1.3 ± 0.8 (range, 0-3) by the last follow-up visit. The mean pre-operative ODI was 61.6 (range, 46-84), which decreased to 16.3 (range, 10-28) at the one month post-operative follow-up and to 8.4 (range, 0-14) by the last follow-up visit. No recurrence was observed in any of the seven patients during the follow-up period. CONCLUSION PELD via a translaminar approach could be a good alternative option for the treatment of soft, highly down-migrated lumbar disc herniation.

Abstract
Purpose. Extraforaminal decompression of the L5 nerve root remains a challenge due to anatomic constraints, severe level-degeneration, and variable anatomy. The purpose of this study is to introduce the use of navigation for transmuscular transtubular decompression at the L5/S1 level and report on radiological features and clinical outcome. Methods. Ten patients who underwent a navigation-assisted extraforaminal decompression of the L5 nerve root were retrospectively analyzed. Results. Six patients had an extraforaminal herniated disc and four had a foraminal stenosis. The distance between the L5 transverse process and the para-articular notch of the sacrum was 12.1 mm in patients with a herniated disc and 8.1 mm in those with a foraminal stenosis. One patient had an early recurrence and another developed dysesthesia that resolved after 3 months. There was a significant improvement from preoperative to postoperative NRS with the results being sustainable at follow-up. ODI was also significantly improved after surgery. According to the Macnab grading scale, excellent or good outcomes were obtained in 8 patients and fair ones in 2. Conclusions. The navigated transmuscular transtubular approach to the lumbosacral junction allows for optimal placement of the retractor and excellent orientation particularly for foraminal stenosis or in cases of complex anatomy.

Abstract
OBJECTIVES To study 1)the efficacy of transforaminal percutaneous endoscopic lumbar discectomy in lumbar disc herniations.2) limitations and advantages of the surgical procedure. 3)morbidity and complications associated with the procedure. MATERIALS AND METHODS This study was carried out on 120 patients who had single level herniated disc Pre-operative assessment of VAS and MSS scoring systems were documented one day prior to surgery. Post operative results were determined by MacNab criteria and by modified Suezawa and Schreiber clinical scoring system (MSS score). RESULTS Maximum patients were in the age group of 31 to 40 years and 83.43% of the patients were males. 80% patients had lumbar disc herniation at L4-L5 level, The mean operative time of endoscopic discectomy was 52.28 minutes and the mean hospital stay was 2.1days.8 cases of L5-S I were abandoned due to high iliac bone and hence their disc could not be accessed. Out of 112 patients who underwent operation, 2 patients developed discitis and 1 was found to have dysesthesia. Also recurrent prolapsed intervertebral disc was seen in 6 cases The mean preoperative and 6 months follow-up VAS score was 8.4 and 1.89 respectively. Mean preoperative and 6 months follow-up Modified Suezawa And Schreiber Clinical Scoring System(MSS Score) was 3.47 and 7.92 respectively. MSS score showed excellent and good outcome in 82.12% patients and Modified Macnab Criteria showed excellent and good outcome in 89.3% patients at 6months follow-up. CONCLUSION TPELD can be a reasonable alternative to conventional microscopic discectomy for the treatment of patients with LDH. We also conclude that TPELD is not an effective procedure for L5-S 1 disc and an open procedure should be opted for better outcomes.

Abstract
OBJECT
Few studies have addressed surgical failures and complications following percutaneous endoscopic lumbar discectomy (PELD), and no previous study has investigated the risk factors that lead to surgical failure. The authors report their experience using PELD for single-level lumbar disc herniation (LDH) to provide insights into the rates of surgical failure and identify potential risk factors that lead to this complication.
METHODS
The authors retrospectively reviewed the medical records of 350 patients who underwent PELD for single-level LDH and identified 36 patients (10.3%) who underwent reoperation due to the failure of PELD.
RESULTS
Patients’ mean visual analog scale of pain scores and Oswestry Disability Index scores improved significantly from 6.6 ± 2.1 and 51.6 ± 19.4 preoperatively to 1.9 ± 1.4 and 28.3 ± 12.0, respectively, at 1 month postoperatively and 1.2 ± 1.1 and 9.3 ± 7.8, respectively, at 1 year postoperatively. The frequencies with which patients took analgesic medications significantly decreased from 74.6% preoperatively to 19.7% at 1 month postoperatively and 10.0% at 1 year postoperatively. Relatively older patients (p = 0.005) and those ≥ 60 years old (p = 0.001) experienced larger numbers of failures compared to younger patients. An analysis of potentially contributing comorbid conditions indicated that significantly more patients with diabetes were present in the PELD failure group (p = 0.017). As surgeons gained familiarity with the procedure, outcomes improved. The failure rate during the authors’ early use of the PELD technique (Cases 1–70) was 17.1%; the failure rate then fell to 5.7% (p = 0.034) (Cases 141–210) before finally stabilizing at 10.0% (Cases 211–280 and Cases 281–350).
CONCLUSIONS
The surgical failure rate following PELD for LDH was 10.3%. Older patients, elderly patients (age ≥ 60 years), and patients with diabetes were at increased risk of surgical failure of PELD, particularly in the early years of the procedure’s use.

Abstract
BACKGROUND Percutaneous endoscopic lumbar discectomy (PELD) has remarkably evolved with successful results. Although PELD has gained popularity for the treatment of herniated disc (HD), the risk of surgical failure may be a major obstacle to performing PELD. We analyzed unsuccessful cases requiring reoperation. OBJECTIVE To find common causes of surgical failure and elucidate the limitations of the conventional PELD technique. METHODS A retrospective review was performed on all patients who had undergone PELD between January 2001 and December 2012. Unsuccessful PELD was defined as a case requiring reoperation within 6 weeks after primary surgery. Chart review was done, and preoperative, intraoperative, and postoperative radiographic reviews were performed. All unsuccessful PELD cases were classified according to the type of HD, location of herniation, extruded disc migration, working channel position, and intraoperative and postoperative findings. RESULTS In 12 years, 10,228 patients had undergone PELD; 436 (4.3%) cases were unsuccessful. The causes were incomplete removal of HDs in 283 patients (2.8%), recurrence in 78 (0.8%), persistent pain even after complete HD removal in 41 (0.4%), and approach-related pain in 21 (0.2%). Incomplete removal of the HD was caused by inappropriate positioning (95 cases; 33.6%) of the working channel and occurred in central HDs (91 cases; 32.2%), migrated HDs (70 cases; 24.7%), and axillary type HDs (63 cases; 22.3%). CONCLUSION Proper surgical indications and good working channel position are important for successful PELD. PELD techniques should be specifically designed to remove the disc fragments in various types of HD.
