Risk factors for surgical site infection after percutaneous endoscopic lumbar discectomy. Int Wound J 2024; 21:e14605. [PMID: 38149500 PMCID: PMC10961887 DOI: 10.1111/iwj.14605] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/30/2023] [Accepted: 12/10/2023] [Indexed: 12/28/2023] Open
Abstract
The objective of this study was to investigate the risk factors associated with surgical site infection (SSI) after percutaneous endoscopic lumbar discectomy (PELD) in patients with lumbar disc herniation (LDH). A retrospective analysis was performed on a cohort of 335 patients who underwent PELD between January 2016 and January 2023. Data were derived from the Hospital Information System (HIS), and a comprehensive statistical assessment was performed using IBM SPSS Statistics version 25.0. Both univariate and multivariate logistic regression analyses assessed a range of risk determinants, such as age, body mass index (BMI), comorbidities, laboratory test parameters and surgery-related variables. The incidence of SSI after PELD was 2.7% (9/335). Univariate analysis highlighted BMI, diabetes mellitus, long-term corticosteroid consumption, surgical time and cerebrospinal fluid leakage as significant predictors of SSI. Multivariate logistic regression identified BMI, diabetes mellitus, long-term corticosteroid consumption, surgical time and cerebrospinal fluid leakage as significant risk factors for SSI after PELD. High BMI, diabetes mellitus, long-term corticosteroid consumption, long surgical time and postoperative cerebrospinal fluid leakage are predisposing factors for SSI in patients undergoing PELD. Precise interventions focused on such risk components, including careful preoperative assessment and strategic postoperative care, are essential to reduce the incidence of SSI and improve surgical efficacy.

Endoscopic Revision Strategies and Outcomes for Recurrent L4/5 Disc Herniation After Percutaneous Endoscopic Transforaminal Discectomy. J Pain Res 2024; 17:761-770. [PMID: 38414800 PMCID: PMC10898476 DOI: 10.2147/jpr.s449949] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/15/2023] [Accepted: 02/17/2024] [Indexed: 02/29/2024] Open
Abstract
Objective We explore the endoscopic revision and surgical techniques for L4/5 recurrent disc herniation (rLDH) after percutaneous endoscopic transforaminal discectomy (PETD). Methods A retrospective study was conducted. From January 2016 to September 2022, 96 patients who underwent percutaneous endoscopic lumbar discectomy for L4/5 rLDH after PETD were enrolled in the study. Based on the revision approach, the patients were divided into PETD group (57 cases) and percutaneous endoscopic interlaminar discectomy (PEID) group (39 cases). Visual Analogue Scale (VAS) for back and leg pain, Oswestry Disability Index (ODI), and modified MacNab standard were recorded to evaluate the clinical outcomes. Results No significant differences were found in the demographic data and intraoperative blood loss between the two groups (P>0.05), but the time of operation and intraoperative X-ray fluoroscopy exposures in the PEID group were significantly less than that in the PETD group (P<0.05). The patients' postoperative clinical indexes gradually improved, and the VAS score, ODI index, and JOA score of the patients in both groups showed significant improvement compared with the preoperative period at the 1-week, 1-month, and 6-month postoperative follow-ups (P < 0.05). There was no serious complication observed during the follow-up. Conclusion For recurrent LDH after PETD of L4/5 segments, percutaneous endoscopic revision can achieve satisfactory results. Among them, PEID has a shorter operative and fluoroscopy time and allows avoidance of the scar that forms after the initial surgery, so it can be considered preferred when both procedures can remove the disk well. However, for some specific types of herniation, a detailed surgical strategy is required.

Stability simulation analysis of targeted puncture in L4/5 intervertebral space for PELD surgery. Front Bioeng Biotechnol 2024; 11:1298914. [PMID: 38260730 PMCID: PMC10800398 DOI: 10.3389/fbioe.2023.1298914] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/22/2023] [Accepted: 12/20/2023] [Indexed: 01/24/2024] Open
Abstract
Introduction: The application prospects of percutaneous endoscopic lumbar discectomy (PELD) as a minimally invasive spinal surgery method in the treatment of lumbar disc herniation are extensive. This study aims to find the optimal entry angle for the trephine at the L4/5 intervertebral space, which causes less lumbar damage and has greater postoperative stability. To achieve this, we conduct a three-dimensional simulated analysis of the degree of damage caused by targeted puncture-based trephine osteotomy on the lumbar spine. Methods: We gathered clinical CT data from patients to construct a lumbar model. This model was used to simulate and analyze the variations in trephine osteotomy volume resulting from targeted punctures at the L4/5 interspace. Furthermore, according to these variations in osteotomy volume, we created Finite Element Analysis (FEA) models specifically for the trephine osteotomy procedure. We then applied mechanical loads to conduct range of motion and von Mises stress analyses on the lumbar motion unit. Results: In percutaneous endoscopic interlaminar discectomy, the smallest osteotomy volume occurred with a 20° entry angle, close to the base of the spinous process. The volume increased at 30° and reached its largest at 40°. In percutaneous transforaminal endoscopic discectomy, the largest osteotomy volume was observed with a 50° entry angle, passing through the facet joints, with smaller volumes at 60° and the smallest at 70°. In FEA, M6 exhibited the most notable biomechanical decline, particularly during posterior extension and right rotation. M2 and M3 showed significant differences primarily in rotation, whereas the differences between M3 and M4 were most evident in posterior extension and right rotation. M5 displayed their highest stress levels primarily in posterior extension, with significant variations observed in right rotation alongside M4. Conclusion: The appropriate selection of entry sites can reduce lumbar damage and increase stability. We suggest employing targeted punctures at a 30° angle for PEID and at a 60° angle for PTED at the L4/5 intervertebral space. Additionally, reducing the degree of facet joint damage is crucial to enhance postoperative stability in lumbar vertebral motion units.

Ultrasound-guided erector spinae plane block for awake spine surgery: A case report and review of the literature. Saudi J Anaesth 2024; 18:126-128. [PMID: 38313734 PMCID: PMC10833031 DOI: 10.4103/sja.sja_548_23] [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: 06/21/2023] [Accepted: 06/23/2023] [Indexed: 02/06/2024] Open
Abstract
Percutaneous endoscopic lumbar discectomy is increasingly gaining recognition as an alternative to open microdiscectomy for the treatment of intervertebral disk herniation. Apart from the neuraxial blockade, and general anesthesia, there is literature demonstrating the performance of endoscopic lumbar discectomy under sole local anesthesia infiltration. This is particularly advantageous as an awake patient assists the surgeon by verbalizing and preventing any inadvertent nerve root damage. However, marked pain has been reported during key steps such as endoscope port installation and radiculolysis. The erector spinae plane (ESP) block is an interfascial paraspinal block that soaks the spinal nerve roots with epidural spread providing superior analgesia for endoscopic discectomy. The utility of ESP block as a perioperative analgesic technique following spine surgery is well established; there are no reports of successful endoscopic discectomy performed using this block. This article emphasizes the utility of ESP block as the sole anesthetic technique for minimally invasive spine surgery in the awake state.

Abstract
STUDY DESIGN Retrospective study. OBJECTIVES To develop machine learning (ML) models to predict recurrent lumbar disc herniation (rLDH) following percutaneous endoscopic lumbar discectomy (PELD). METHODS We retrospectively analyzed 1159 patients who had undergone single-level PELD for lumbar disc herniation (LDH) between July 2014 to December 2019 at our institution. Various preoperative imaging variables and demographic metrics were brought in analysis. Student's t test and Chi-squared test were applied for univariate analysis, which were feature selection for ML models. We established ML models to predict rLDH: Artificial neural networks (ANN), Extreme Gradient Boost classifier (XGBoost), KNeighborsClassifier (KNN), Decision tree classifier (Decision Tree), Random forest classifier (Random Forest), and support vector classifier (SVC). RESULTS A total 130 patients (11.22%) were diagnosed as rLDH in 1159 patients. Recurrence occurred within 10.25 ± 11.05 months. Body mass index (BMI) (P = .027), facet orientation (FO) (P < .001), herniation type (P = .012), Modic changes (P = .004), and disc calcification (P = .013) are significant factors in univariate analysis (P < .05). Extreme Gradient Boost classifier, Random Forest, ANN showed fine area under the curve, .9315, .9220, and .8814 respectively. CONCLUSION We developed a deep learning and 2 ensemble models with fine performance in prediction of rLDH following PELD. Predicting re-herniation before surgery has the potential to optimize decision-making and meaningfully decrease the rates of rLDH following PELD. Our ML model identified higher BMI, lower FO, Modic changes, disc calcification in a non-protrusive region, and herniation type (noncontained herniation) as significant features for predicting rLDH.

Percutaneous endoscopic lumbar discectomy in lumbar disc herniation with posterior ring apophysis fracture: A case report in a 15-year-old child. Medicine (Baltimore) 2023; 102:e36213. [PMID: 38206687 PMCID: PMC10754556 DOI: 10.1097/md.0000000000036213] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/29/2023] [Accepted: 10/30/2023] [Indexed: 01/13/2024] Open
Abstract
RATIONALE Lumbar disc herniation (LDH) with posterior ring apophysis fracture (PRAF) is rather rare in children, and in all age-stratified LDH patients, the incidence of RAF was 5.3% to 7.5%. Interestingly, the incidence of LDH with RAF in children (15%-32%) is several times higher than in adults, the mis-diagnosis of which may lead to delayed treatment. PATIENT CONCERNS Here, we report a 15-year-old schoolboy who suffered from sudden low back pain and radiating pain in both lower limbs after sport activities. Symptoms persisted after 3 months of conservative treatment. Computer radiography and magnetic resonance imaging indicated central disc herniation with PRAF at L4-5. DIAGNOSIS LDH with PRAF. INTERVENTIONS The herniated disc and epiphyseal fragments were successfully excised by the percutaneous endoscopic lumbar discectomy minimal-invasive technique. OUTCOMES Surgery was successful. Symptoms were immediately relieved postoperatively with a wound of only about 7.0 mm. Discharged on the next day. No perioperative complications occurred. Moreover, the imaging and clinical outcomes were also more satisfactory during the post-operative 15 months outpatient follow-up. LESSONS Pediatric LDH with PRAF is extremely uncommon, and there is a lack of training among physicians for such cases, which may lead to delayed diagnosis and treatment. Once a diagnosis for LDH with PRAF is established, percutaneous endoscopic lumbar discectomy is a safe and effective minimally invasive treatment to be considered, and we hope that this technique can provide more assistance in the future.

Evaluation of Augmented Reality Surgical Navigation in Percutaneous Endoscopic Lumbar Discectomy: Clinical Study. Bioengineering (Basel) 2023; 10:1297. [PMID: 38002421 PMCID: PMC10669401 DOI: 10.3390/bioengineering10111297] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/12/2023] [Revised: 11/03/2023] [Accepted: 11/07/2023] [Indexed: 11/26/2023] Open
Abstract
BACKGROUND The puncture procedure in percutaneous endoscopic lumbar discectomy (PELD) is non-visual, and the learning curve for PELD is steep. METHODS An augmented reality surgical navigation (ARSN) system was designed and utilized in PELD. The system possesses three core functionalities: augmented reality (AR) radiograph overlay, AR puncture needle real-time tracking, and AR navigation. We conducted a prospective randomized controlled trial to evaluate its feasibility and effectiveness. A total of 20 patients with lumbar disc herniation treated with PELD were analyzed. Of these, 10 patients were treated with the guidance of ARSN (ARSN group). The remaining 10 patients were treated using C-arm fluoroscopy guidance (control group). RESULTS The AR radiographs and AR puncture needle were successfully superimposed on the intraoperative videos. The anteroposterior and lateral AR tracking distance errors were 1.55 ± 0.17 mm and 1.78 ± 0.21 mm. The ARSN group exhibited a significant reduction in both the number of puncture attempts (2.0 ± 0.4 vs. 6.9 ± 0.5, p = 0.000) and the number of fluoroscopies (10.6 ± 0.9 vs. 18.5 ± 1.6, p = 0.000) compared with the control group. Complications were not observed in either group. CONCLUSIONS The results indicate that the clinical application of the ARSN system in PELD is effective and feasible.

The effect of annulus fibrosus incision and foraminoplasty on lumbar biomechanics in percutaneous endoscopic lumbar discectomy: a finite element analysis. Comput Methods Biomech Biomed Engin 2023:1-9.

Abstract
The objective of this study was to analyze the effects of annulus fibrosus incision and foraminoplasty on lumbar biomechanics during posterior lateral approach translaminar percutaneous endoscopic lumbar discectomy (PELD) using a lumbar 4/5 segment model and three-dimensional finite element analysis (FEA). We created a model of the L4 to L5 segment and performed simulated foraminoplasty, annulus fibrosus incision, and a combined operation. The models were tested under six working conditions, and we recorded the deformation and equivalent strain/stress of each group. Results showed that foraminoplasty can affect the stability and rotation axis of the segment during rotation without significantly impacting discal stress. Conversely, annulus fibrosus incision significantly increases discal stress except for when the patient is doing a forward flexion movement. We recommend that surgical maneuvers minimize the removal and destruction of the annulus fibrosus and that rotation movements are avoided during the short-term recovery period following PELD surgery.

Abstract
STUDY DESIGN Systematic review. OBJECTIVES It remains unknown whether general anesthesia (GA) or local ± epidural anesthesia (LA) results in superior outcomes with percutaneous endoscopic lumbar discectomy (PELD). The present study sought to examine the impact of anesthesia type on patient-reported outcomes (PROs) and complications with PELD. METHODS Systematic review and meta-analysis examining PELD performed under GA or LA was conducted. Patient-reported outcomes including Visual Analog Scale (VAS)-leg/back, and Oswestry Disability Index (ODI) scores were collected. Complication, recurrent disc herniation, durotomy, and reoperation rates as well as surgical data were recorded. All outcomes were compared between pooled studies examining GA or LA. RESULTS Sixty-eight studies consisting of 5269 patients (724 GA, 4465 LA) were included in the meta-analysis. Overall complication rate was significantly higher in the GA group (9% vs 4%, P = .003). Durotomy rates, length of stay, recurrent disc herniation and reoperation rates were similar between groups. At the first follow-up timepoint, the LA group demonstrated significant improvements in VAS back and ODI scores (P < .05) while the GA group did not (P > .05). At the final follow-up (> 6 months), the percent of patients achieving an excellent McNab score was significantly higher in the GA vs LA group (P < .001). CONCLUSIONS Percutaneous endoscopic lumbar discectomy with LA may be associated with greater short-term improvement in VAS back pain and ODI scores. General anesthesia may be associated with more durable pain relief but a higher complication rate. Further systematic investigation is necessary to determine what short and long term benefits are associated with PELD performed under LA and GA.

Abstract
OBJECTIVE To investigate the risk factors of reoperation after percutaneous endoscopic lumbar discectomy (PELD) due to recurrent lumbar disc herniation (rLDH) and to establish a set of individualized prediction models. METHODS Patients who underwent PELD successfully from January 2016 to February 2022 in a single institution were enrolled in this study. Six methods of machine learning (ML) were used to establish an individualized prediction model for reoperation in rLDH patients after PELD, and these models were compared with logistics regression model to select optimal model. RESULTS A total of 2603 patients were enrolled in this study. 57 patients had repeated operation due to rLDH and 114 patients were selected from the remaining 2546 nonrecurrent patients as matched controls. Multivariate logistic regression analysis showed that disc herniation type (P < .001), Modic changes (type II) (P = .003), sagittal range of motion (sROM) (P = .022), facet orientation (FO) (P = .028) and fat infiltration (FI) (P = .001) were independent risk factors for reoperation in rLDH patients after PELD. The XGBoost AUC was of 90.71%, accuracy was approximately 88.87%, sensitivity was 70.81%, specificity was 97.19%. The traditional logistic regression AUC was 77.4%, accuracy was about 77.73%, sensitivity was 47.15%, specificity was 92.12%. CONCLUSION This study showed that disc herniation type (extrusion, sequestration), Modic changes (type II), a large sROM, a large FO and high FI were independent risk factors for reoperation in LDH patients after PELD. The prediction efficiency of XGBoost model was higher than traditional Logistic regression analysis model.

Abstract
The effect of spinal anatomical anomalies on the efficacy of percutaneous endoscopic lumbar discectomy (PELD) for disc herniation repair is unclear. This retrospective review aims to assess the safety and effectiveness of PELD for treating L5-S1 disc herniation with a range of characteristics and to determine the prevalence of lumbosacral transitional vertebrae (LSTV) anatomical anomalies to facilitate pre-surgical planning. From July 2005 to June 2019, 345 patients with L5-S1 disc herniations were treated with PELD. The primary outcome was 1-year postoperative visual analogue scale scores for low back and lower limb pain. The secondary outcomes included the surgical approach used, lumbosacral bony anomalies, presence of a ruptured disc or severely calcified disc, pediatric lumbar disc herniation, recurrent disc herniation management, and the long-term outcome. visual analogue scale scores for most patients were significantly improved after surgery. The prevalence of LSTVs was 4.05% (14/345 patients) in lumbar sacralization and 7.53% (26/345 patients) in sacral lumbarization. The prevalence of ruptured and severely calcified discs was 18.55% (64/345) and 5.79% (20/345), respectively. The prevalence of pediatric lumbar disc herniation was 2.02% (7/345). The recurrence rate was 4.34% (15/345). Two durotomy cases without sequelae and 8 cases of lower limb dysesthesia lasting longer than 3 months postoperatively were reported. PELD is safe and effective for treating L5-S1 disc herniation, including cases complicated by calcified lumbar disc herniation, disc rupture with migration, and the presence of LSTV. Appropriate imaging is essential to identify case-specific factors, including the prevalent LSTV anatomical anomalies, before surgery.

Abstract
Background Lumbar disc herniation (LDH) linked with posterior ring apophysis separation (PRAS) is a rare and distinct subset of disc herniation. Few studies have evaluated the clinical efficacy of percutaneous endoscopic lumbar discectomy (PELD), which is a procedure used to treat LDH linked with PRAS. Objectives To evaluate the clinical efficacy and safety of PELD in the treatment of LDH linked with PRAS. Methods Patients who met inclusion criteria (n = 67; 40 males and 27 females) underwent PELD. General and operation-related information and perioperative complications of the patients were recorded. Clinical efficacy was measured using the Visual Analog Scale (VAS) and Oswestry Disability Index (ODI) during the follow-up period. Results The mean operation time was 118.04 ± 19.31 min and the mean blood loss was 22.84 ± 15.89 ml. The VAS and ODI scores continued to improve immediately after the surgery to the last follow-up. Four patients experienced postoperative complications i.e., herniation recurrences. The conditions of the patients with the complications improved after treatment. Conclusions PELD has reliable efficacy and safety in the treatment of LDH linked with PRAS.

Abstract
Objective This study aims to compare the efficacy of percutaneous endoscopic lumbar discectomy (PELD) in treating adolescent posterior ring apophysis fracture (APRAF) accompanied by lumbar disc herniation (LDH) and lumbar disc herniation alone. Methods Herein we present a case series of adolescent patients who underwent PELD surgery from June 2017 to September 2021. All patients were divided into two distinct groups (ie Group A and B), based on their preoperative Computed tomography (CT) scans. Group A included patients with PRAF (type III) accompanied by LDH. Group B patients had LDH alone. The general clinical characteristics, clinical outcomes, and complications in patients from the two groups were assessed and compared. Results Compared to before surgery, the back and leg visual analog scores (VAS) and Oswestry Disability Index (ODI) were markedly improved in both groups' patients at all follow-ups. Notably, no significant differences were observed in the back and leg VAS scores, and ODI values between the two groups at different time points after surgery. The mean intraoperative blood loss was significantly lower in Group B, relative to Group A. The mean operation time was significantly shorter in Group B, compared to Group A. There was no statistically significant difference in complication and recurrence rates between the two groups. Conclusion APRAF (type III) accompanied by LDH and LDH alone can obtain roughly equal surgical effects through PELD surgery and turns out to be a safe and effective surgical approach.

BACKGROUND The purpose of this study was to analyze unilateral biportal endoscopic discectomy (UBE) and percutaneous endoscopic lumbar discectomy (PELD) for the treatment of lumbar disc herniation. METHODS PubMed, EMBASE, Web of Science, Cochrane Database, CNKI, and Wanfang databases were searched online. All statistical analyses were performed using STATA 16.0. RESULTS The selection criteria were met by 6 studies with a total of 281 patients (142 cases in the UBE group and 139 cases in the PELD group) and good methodological quality. PELD has the potential to improve outcomes such as operation time and intraoperative hemorrhage (MD = 36.808, 95% CI (23.766, 49.850), P = .000; MD = 59.269, 95% CI (21.527, 97.010), P = .000) compared with UBE. No differences were found in the back pain VAS score at preoperative (MD = -0.024, 95% CI [-0.572, 0.092], P = .998), at 1 day after operation (MD = -0.300, 95% CI [-0.845, 0.246], P = .878), the VAS score of leg pain at preoperative (MD = -0.099, 95% CI [-0.417, 0.220], P = .762), at 1 day after operation (MD = 0.843, 95% CI [0.193, 1.492], P = .420), at 1 month after operation (MD = -0.027, 95% CI [-0.433, 0.380], P = .386), at 6 months after operation (MD = 0.122, 95% CI [-0.035, 0.278], P = .946), hospital stay (MD = 3.708, 95% CI [3.202, 4.214], P = .000) and other clinical effects between UBE and PELD group. CONCLUSIONS There are no significant differences in clinical efficacy between UBE and PELD, according to the research. However, PELD has the potential to improve outcomes such as operation time and intraoperative hemorrhage. As just a result, PELD is better suited in the treatment of lumbar disc herniation.

Clinical Outcomes and Quality of Life in Elderly Patients Treated with a Newly Designed Double Tube Endoscopy for Degenerative Lumbar Spinal Stenosis. Orthop Surg 2022; 14:1359-1368. [PMID: 35633039 PMCID: PMC9251268 DOI: 10.1111/os.13304] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/20/2020] [Revised: 04/03/2022] [Accepted: 04/11/2022] [Indexed: 11/28/2022] Open
Abstract
Objective To evaluate the clinical outcome and quality of life in elderly patients in poor conditions with unilateral symptomatic degenerative lumbar spinal stenosis (DLSS) who were treated with percutaneous endoscopic lumbar discectomy (PELD) assisted by double tubes. Methods This study was designed retrospectively. From June 2017 to June 2018, 31 consecutive elderly patients who were presented with unilateral symptomatic DLSS, underwent PELD assisted by double tubes under local anesthesia. American Society of Anesthesiology score (ASA) was used to evaluate the patients' conditions. The operative time, intraoperative blood loss, hospital stay, and complications were evaluated. Clinical outcomes were assessed by the visual analog scale (VAS), Oswestry disability index (ODI), and modified Macnab criteria. Short Form 36 (SF‐36) was used to evaluate the life quality. The CT or MRI was used to evaluate the spinal area. Results Thirty‐one patients were enrolled and 25 cases achieved at least a 24‐month follow‐up. Three patients were lost to follow‐up and three patients died from other diseases. A total of 76% (19/25) of the patients presented an ASA score of more than 3. The mean operative time was 67.80 min, the mean blood loss was 18.2 ml, and the hospital stay was 6.92 days. The postoperative 12‐month follow‐up VAS score significantly decreased compared with that before the operation (1.12 ± 0.73 vs. 5.12 ± 1.81, p < 0.01). Although the VAS score decreased at the final follow‐up, there was no significant difference compared with that at the 12‐month follow‐up (0.92 ± 0.64 vs. 1.12 ± 0.73, p = 0.549). So did the ODI. Also, there was no difference in the ODI scores between the 12‐month follow‐up and the final follow‐up (12.52 ± 5.58 vs. 9.44 ± 6.32, p = 0.172). The overall excellent rate was 92% (23/25) at the final follow‐up. The scores of the physical function, mental function, and social function of SF‐36 after the operation improved significantly compared with those before operation (p < 0.05). But there was no difference in the physical function score (84.00 ± 6.29 vs 84.40 ± 6.18, p = 0.871), mental function score (81.76 ± 8.01 vs 81.68 ± 6.67, p = 0.974), or social function score (115.50 ± 13.64 vs 118.50 ± 12.03, p = 0.437) between the 12‐month follow‐up and the final follow‐up. There were no differences in the VAS, ODI, and SF‐36 between the L4/5 and L5S1 groups before operation or at the final follow‐up (p > 0.05). The postoperative radiology indicated the lateral recess is opened and the area of the dural sac is expanded. Two cases (8.0%, 2/25) experienced recurrence and a secondary PELD was performed. Conclusions PELD assisted by double tubes is effective for unilateral symptomatic DLSS in elderly patients with comorbidities and could improve life quality.

Abstract
This study aimed to investigate the relationship between depression and outcome of percutaneous endoscopic lumbar discectomy (PELD) in patients with lumbar disc herniation. We examined 268 patients who underwent PELD for lumbar disc herniation and were followed for five years. Patients were grouped according to mood: normal mood (159 patients) and continuous depression (109 patients). Depressive symptoms were assessed using the 21-item Beck Depression Inventory. Back and leg pain were assessed using the visual analogue scale. Subjective disability was measured using the Oswestry Disability Index. Neurological function and physical disability were assessed using the Japanese Orthopaedic Association score. Disc-height ratio and intervertebral instability were measured to assess lumbar stability. Clinical and radiological data were recorded before surgery and at the 3-month, 6-month, 1-year, 2-year, and 5-year follow-ups. Although the Japanese Orthopaedic Association, visual analogue scale, and Oswestry Disability Index scores did not significantly differ between groups before surgery, all three scores significantly differed between groups at all follow-up time points after PELD (p < 0.05). Measurements of disc-height ratio and intervertebral instability did not significantly differ between the groups before surgery nor at any point after surgery (P > 0.05). Patients with continuous depression exhibited less improvement in symptom severity and disability score after PELD at all time points in the five years after surgery. Depression had little effect on lumbar vertebral stability after PELD. Interventions to detect and treat depression should be performed before and after surgery.

Abstract
Purpose Percutaneous endoscopic lumbar discectomy (PELD) is usually used to treat lumbar disc herniation (LDH). This study aims to describe PELD by foraminoplasty in the treatment of far-downward migrated LDH and to demonstrate the clinical efficacy by a retrospective evaluation. Patients and Methods Between January 2017 and July 2018, 41 patients with far-downward migrated LDH were treated with PELD by foraminoplasty at the base of the superior articular process (SAP). Clinical efficacy was evaluated with a visual analogue scale (VAS) score, the Oswestry disability index (ODI), and the modified Macnab criteria. Postoperative follow-up data (1 month, 6 months, 18 months) were recorded. Results The surgical levels included L2/3 (1 patient), L3/4 (1 patient), L4/5 (17 patients), and L5/S1 (22 patients). The VAS and ODI scores indicated a significant improvement 18 months after surgery (mean ± standard deviation, VAS, 6.9±1.3 versus 0.5±0.8; ODI, 66.3±12.2 versus 14.0±8.2, respectively). Based on the modified Macnab criteria, 92.7% of patients had a good-to-excellent rate. There were three patients with a dural tear, and one patient had recurrent disc herniation. Conclusion PELD by foraminoplasty at the base of the superior articular process is a good method for treating far-downward migrated LDH.

Abstract
Purpose Percutaneous endoscopic lumbar discectomy (PELD) is a minimally invasive spinal surgery for huge lumbar disc herniation (HLDH). The aim of this study was to investigate the short-term clinical effectiveness of PELD for HLDH with complete dural sac stenosis via an interlaminar approach. Methods We retrospectively analyzed 56 patients diagnosed with HLDH with complete dural sac stenosis and treated with PELD via an interlaminar approach. Numerical rating scale (NRS), Oswestry disability index (ODI), and modified Japanese orthopedic association (mJOA) were used to evaluate preoperative conditions as well as outcomes at 1, 3, 6 and 12 months postoperatively. At the final follow-up, the clinical effects were evaluated using modified MacNab criteria. Results All patients were followed for at least 12 months. At 1, 3, 6, and 12 months postoperatively, the NRS and ODI scores were significantly decreased, and the mJOA score significantly increased compared with preoperative results (P<0.001). According to the Macnab criteria at the final follow-up, it was excellent in 42 patients (75%), good in 9 (16.1%), and fair in 5 (8.9%). The overall clinical satisfactory rate was 91.1%. Conclusion Our study results suggest that percutaneous endoscopic interlaminar discectomy (PEID) is available for the treatment of HLDH with complete dural sac stenosis, whose benefits are rapid recovery, complete removal of the herniated disc, effective spinal canal decompression, fewer complications, and significant relief of clinical symptoms.

Abstract
OBJECTIVE The purpose of this research was to investigate the outcomes between unilateral biportal endoscopic discectomy (UBE) and percutaneous endoscopic lumbar discectomy (PELD) for the single L4/5-level lumbar disk herniation (sLDH). METHODS From January 2018 to January 2021, a total of 40 patients with sLDH were retrospectively analyzed in this study. All the patients had received spinal surgeries in Affiliated Hospital of Nantong University and Affiliated Nantong Hospital 3 of Nantong University. Among them, 20 patients were treated with PELD (PELD group), and 20 patients were treated with UBE discectomy (UBE group). Postoperative length of hospital stay, estimated blood loss, operation time, and clinical complications of the patients were compared between the two groups. The visual analog scale (VAS) and Oswestry Disability Index (ODI) were measured before surgeries and 3 days, 1, and 6 months after surgeries. RESULTS Compared with the UBE group, the PELD group had obviously less intraoperative blood loss, shorter operative time, and shorter hospital stay. The differences in the rate of complications were not statistically significant between the two groups. The VAS score and the ODI score of the two groups had a great reduction after operation. In addition, both the groups had satisfactory clinical outcome; the VAS score and ODI of the PELD group decreased more obviously. CONCLUSION The UBE for sLDH yielded similar clinical outcomes to PELD as minimally invasive surgeries; however, PELD is superior to UBE in terms of intraoperative blood loss, operative time, postoperative hospitalization, and short-term postoperative pain relief. The advantages and disadvantages of the two surgeries should be circumspectly balanced when evaluating a patient for a minimally invasive surgery for sLDH, selecting the most appropriate surgical method for patients.

Abstract
Objective Pediatric lumbar disc herniation (LDH), although uncommon, causes significant
pain, discomfort, and sometimes disability. We examined the efficacy of
percutaneous endoscopic lumbar discectomy (PELD) for pediatric LDH and the
degree of lumbar disc degeneration at 1 year after PELD. Methods We retrospectively reviewed the data of pediatric patients with LDH who
underwent PELD from December 2007 to July 2018. The patients’ symptoms,
physical examination findings, clinical images, visual analog scale (VAS)
scores, Oswestry Disability Index (ODI), and perioperative results (blood
loss, length of hospital stay, and complications) were obtained from the
medical records. Lumbar disc degeneration was graded using the modified
Pfirrmann grading system at the 1-year postoperative magnetic resonance
imaging (MRI) examination. Results Six boys and four girls who underwent PELD were evaluated. The patients’ mean
age was 15.6 years (range, 13–17 years). The mean VAS score for low back
pain, mean VAS score for lower limb pain, and mean ODI preoperatively and 1
year postoperatively were 6.2 and 0.3, 6.9 and 0.5, and 20 and 0.1,
respectively. MRI showed significant disc degeneration after PELD. Conclusions Treating pediatric LDH with PELD is safe and effective. It relieves pain and
reduces disability. However, lumbar disc degeneration still occurs.

Percutaneous endoscopic lumbar discectomy compared with other surgeries for lumbar disc herniation: A meta-analysis. Medicine (Baltimore) 2021; 100:e24747. [PMID: 33655938 PMCID: PMC7939231 DOI: 10.1097/md.0000000000024747] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/16/2020] [Accepted: 01/16/2021] [Indexed: 01/04/2023] Open
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.

Minimum Seven-Year Follow-Up Outcomes of Percutaneous Endoscopic Lumbar Discectomy for Lumbar Degenerative Disease. Int J Gen Med 2021; 14:779-785. [PMID: 33707968 PMCID: PMC7943319 DOI: 10.2147/ijgm.s293400] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/25/2020] [Accepted: 02/22/2021] [Indexed: 12/25/2022] Open
Abstract
Purpose To investigate the long-term (> 7 years) clinical outcomes of percutaneous endoscopic lumbar discectomy for lumbar degenerative disease to address postoperative problems including postoperative dysesthesia (POD), residual back pain and segmental instability. Methods Inclusion and exclusion criteria were established. All patients who met the above criteria were treated by PELD using the transforaminal approach. Limited discectomy was performed to preserve the disc material in the intervertebral space as much as possible. The Oswestry Disability Index (ODI), Japanese Orthopaedic Association (JOA) score, visual analog scale (VAS) score for back pain (VAS-B) and leg pain (VAS-L) and Modified MacNab’s criterion were used for clinical evaluation. Radiographic parameters including height of intervertebral disc and segmental instability were also evaluated. Results Forty-two patients (24 men and 18 women) who met our inclusion and exclusion criteria were included in our study. The average follow-up period was 95.71±5.63 months (ranging from 87 to 105 months). There were no neurological complications associated with the operation. POD was found in 14.29% of patients, while only 2 patients (4.76%) complained of mild dysesthesia at final follow-up. Two patients (4.76%) required revision surgery during the follow-up period. The final follow-up ODI, JOA score, VAS-B and VAS-L were significantly better than preoperative values. The average disc-height ratio was 84.52±5.66% of the preoperative disc height. No instability at the operation level was noted at final follow-up. Conclusion Our study showed that PELD using the transforaminal approach can provide favorable results after a long-term follow-up period. POD is a common complication at initial prognosis. Limited discectomy can preserve the disc height well and minimize the risk of residual back pain.

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.

Abstract
RATIONALE Percutaneous endoscopic lumbar discectomy (PELD) is an effective treatment for lumbar disc herniation and postoperative discal pseudocyst (PDP) can rarely develop after PELD. PATIENT CONCERNS A 30-year-old man experienced low back pain and pain in the right lower extremity for 1 month, which aggravated for 3 days. DIAGNOSES Preoperative CT and MRI showed lumbar disc herniation at the L4/5 level. Then the patient underwent PELD under local anesthesia and his symptoms disappeared immediately after surgery. After 37 days of PELD, the patient complained of recurrent low back pain on the right side, and pain on the outer side of his lower leg. MR imaging revealed cystic mass with low signal on T1-weighted images (T1WI), and high signal on T2-weighted images (T2WI). The patient was diagnosed with a symptomatic PDP after PELD. INTERVENTIONS Initially, the patient was treated with conservative treatment, including administration of aescin and mannitol by intravenous infusion, physical therapy, sacral canal injection. Then he underwent discography at L4/5 and ozone ablation under local anesthesia. OUTCOMES The patient's condition improved significantly after 1 week of surgery and was discharged. One-year and 3-month follow-up revealed no recurrence of low back pain and leg pain. LESSONS PDP is one of the rare complications of PELD, usually occurs in young patients. Patients with PDP have a low signal intensity on T1WI and high signal intensity on T2WI, which can be treated by conservative treatment, interventional therapy, and surgical treatment.

Abstract
Objective The purpose of this study was to compare the outcomes between percutaneous endoscopic lumbar discectomy (PELD) and minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF) for the revision surgery for recurrent lumbar disc herniation (rLDH) after PELD surgery. Patients and Methods A total of 46 patients with rLDH were retrospectively assessed in this study. All the patients had received a PELD in Peking University First Hospital between January 2015 and June 2019, before they underwent a revision surgery by either PELD (n=24) or MIS-TLIF (n=22). The preoperative data, perioperative conditions, complications, recurrence condition, and clinical outcomes of the patients were compared between the two groups. Results Compared to the MIS-TLIF group, the PELD group had significantly shorter operative time, less intraoperative hemorrhage, and shorter postoperative hospitalization, but higher recurrence rate (P<0.05). Complication rates were comparable between the two groups. Both groups had satisfactory clinical outcomes at a 12-month follow-up after the revision surgery. The PELD group also showed significantly lower visual analog scale (VAS) scores of back pain and Oswestry disability index (ODI) in one month after the revision surgery, whereas the difference was not detectable at six- and 12-month follow-ups. Conclusion Both PELD and MIS-TLIF are effective as a revision surgery for rLDH after primary PELD. PELD is superior to MIS-TLIF in terms of operative time amount of intraoperative hemorrhage and postoperative hospitalization. However, its higher postoperative recurrence rate must be considered and patients should be well informed, when making a decision between the two surgical approaches.

Combination of Gluteal Trigger Points Dry Needling and Percutaneous Endoscopic Lumbar Discectomy for Complex Low Back-Related Leg Pain. J Pain Res 2020; 13:3125-3129. [PMID: 33262646 PMCID: PMC7700084 DOI: 10.2147/jpr.s279592] [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] [Subscribe] [Scholar Register] [Received: 08/31/2020] [Accepted: 10/23/2020] [Indexed: 11/23/2022] Open
Abstract
Purpose Causes of low back-related leg pain (LBLP) can be complex and diverse. A detailed medical history, physical examination, laboratory tests, and imaging are necessary to accurately distinguish the pathomechanisms of LBLP and determine the most appropriate treatment. Case In this study, we report the first documented case in which the combination of dry needling (DN) and percutaneous endoscopic lumbar discectomy (PELD) was used for a patient with active myofascial trigger points (MTrPs) in the gluteus minimus muscle as well as L3-4 lumbar disc herniation (LDH). This 63-year-old woman complained of LBLP for 3 months. After careful examination and analysis, we determined this pain originated from two active MTrPs in the gluteal region and not LDH in L3-4. We first performed MTrPs DN, and the patient's LBLP was relieved completely. We then performed PELD at the L3-4 level for residual numbness on the medial and anterior aspect of the left lower limb. Finally, the patient received a satisfactory result. Conclusion The gluteal MTrPs test may be used as a routine examination for patients with LBLP, especially when clinical findings are discordant with imaging results.

Abstract
RATIONALE Percutaneous endoscopic lumbar discectomy (PELD) is a minimally invasive technique for removing nucleus pulposus and achieving neural decompression via a posterolateral approach. PELD is known to have a very low rate of complications during the perioperative period. Although quite rare, seizures can occur in patients undergoing PELD. PATIENT CONCERNS A 58-year-old man with severe low back pain underwent the PELD procedure under general anesthesia. During the recovery phase after general anesthesia, the patient developed a tonic-clonic seizure. Two additional episodes occurred subsequently. DIAGNOSES Bilateral disc swelling indirectly supports the diagnosis of intracranial hypertension. INTERVENTIONS Midazolam and propofol were administered to control seizures. 1.0 g phenobarbital sodium was administered by intravenous injection. Ten milligrams of furosemide and 250 mL of mannitol (20%) were prescribed sequentially. Two hundred milligrams of hydrocortisone and an ice bag were used to protect the brain. Urapidil, metoprolol, and nicardipine were intermittently used to control his blood pressure. A sustained release of sodium valproate was administered and continued prophylactically for 4 weeks. OUTCOMES No further seizures were recorded and the patient recovered well. LESSONS We conclude that total volume of fluid used for irrigation was considered a possible cause of seizure. This case illustrates the fact that irrigation should be performed cautiously in PELD procedure. And anesthesiologists should be familiar with the management strategies of perioperative acute seizures.

Abstract
BACKGROUND Percutaneous endoscopic lumbar discectomy (PELD) has routinely performed in recent years for lumbar disc herniation because of the advances in technology of minimally invasive spine surgery. Two common operating routes for PELD have been introduced in the literature: transforaminal approach (TA) and interlaminar approach (IA). The purpose of our current retrospective clinical trial was to study whether the effect of IA-PELD is better than TA-PELD in the incidence of complications and clinical prognosis scores in the patients with L5-S1 lumbar disc herniation. METHODS Our present research was approved by the institutional review board in the Second Hospital of Nanjing. All the patients offered the informed consent. All the procedures containing human participants were conducted on the basis of the Helsinki Declaration. A retrospective analysis was implemented on 126 patients with L5-S1 disc herniated radiculopathy from March 2016 to March 2018, who were treated with the PELD utilizing the IA technique or the TA technique. Relevant data, such as the patients demographics, surgical duration, length of hospital stay, hospitalization expenses, complications were recorded. In our work, the outcomes of patients were determined at baseline, 6 months, 12 months, and 24 months after treatment. The measure of primary outcome was Oswestry Disability Index score. The other outcomes measured were Numeric Rating Scale pain scale, surgical duration, length of hospital stay, and complications. The software of SPSS Version 22.0 (IBM Corporation, Armonk, NY) was applied for the analysis of all the statistical data. When P value <.05, it was considered to be significant in statistics. RESULTS This protocol will provide a solid theoretical basis for exploring which PELD approach is better in treatment of lumbar disc herniation. TRIAL REGISTRATION This study protocol was registered in Research Registry (researchregistry5988).

Abstract
BACKGROUND Compared with open lumbar microdiscectomy, percutaneous endoscopic lumbar discectomy (PELD) has the advantages of remarkable preservation of paravertebral structures, less bleeding, shorter operation time and fewer complications, it is a common method for the treatment of lumbar disc herniation (LDH). Local anesthesia is recommended during PELD. However, intraoperative pain is sometimes difficult to control satisfactorily. The efficacy of bilateral intervertebral foramen block (IFB) for pain management in PELD remains unclear. Therefore, this regimen is utilized in a randomized controlled trial for the assessment the safety and effectiveness of bilateral IFB for PELD pain control. METHOD This is a single center and randomized controlled trial which will be implemented from September 2020 to September 2021. This research protocol is in accordance with the items of the Standard Protocol for Randomized Trials, which was authorized through the Ethics Committee of Huzhou Central Hospital & Affiliated Centre Hospital of Huzhou University (HZCH0465-0864). 100 participants who undergo PELD will be analyzed. Inclusion criteria containsThe exclusion criteria contains:Patients will be randomly divided into bilateral IFB group (with 50 patients) and local infiltration analgesia group (with 50 patients). Primary outcomes are pain score at different time points. The secondary outcomes are the operative time, radiation exposure time, length of hospital stay and postoperative complications. All the analysis is implemented through applying the IBM SPSS Statistics for Windows, version 20 (IBM Corp., Armonk, NY, USA). RESULTS The clinical outcome variables between groups are illustrated in the Table 1. CONCLUSION This investigation can offer a reliable basis for the effectiveness and safety of IFB in treating the PELD pain. TRIAL REGISTRATION This study protocol is registered in Research Registry (researchregistry5985).

Abstract
OBJECTIVE The aim of this study was to evaluate the clinical results of a Bi-needle technique and conventional transforaminal endoscopic spine system (TESSYS) technique for percutaneous endoscopic lumbar discectomy (PELD) in treating patients with intervertebral disc calcification (IDC). BACKGROUND PELD has gained acceptance for treating patients with IDC. The Bi-needle technique was designed to improve the efficiency and safety of PELD. METHOD Bi-needle and TESSYS group within each cohort were balanced using 1:1 propensity score matching. Finally, 32 patients with IDC treated by Bi-needle technique from December 2015 to September 2017 were enrolled and 25 patients treated by TESSYS technique from the same spine surgery center between January 2013 and October 2017 were enrolled as controls. RESULTS Propensity score matching generated 22 Bi-needle and 22 TESSYS patients. There were no significant differences in visual analog scale and lumbar Japanese Orthopaedic Association scores between Bi-needle and TESSYS group. Operative time and rate of complications in the Bi-needle was significantly better than the TESSYS group (p < 0.01). CONCLUSIONS Both surgical methods achieved good clinical outcomes. However, compared with the TESSSY technique, operative time of the Bi-needle technique is shorter, and rate of complications is lower.

Abstract
Objective To identify effect of quantitative indicators of ilium height on approach of percutaneous endoscopic lumbar discectomy (PELD) treatment in patients with L 5, S 1 lumbar disc herniation. Methods A retrospective study between May 2014 and March 2016 was conducted, including 100 patients with disc herniation at L 5, S 1, who were initially enrolled for the PELD treatment. Among them, 66 patients were successfully treated with PELD (group A), and the other 34 patients failed to perform puncture, catheterization, or microscopical operation due to the influence of iliac bone and other peripheral bone structures and treated with alternative surgical plans. By analyzing the X-ray films of lumbar vertebrae (including bilateral ilium) of the two groups before operation, the concept of ilium height rate and ilium angle rate was put forward innovatively. The ilium height rate and ilium angle rate of the two groups were measured and compared, and the diagnostic critical points of ilium height rate and ilium angle rate were determined by ROC curve analysis. Results The ilium height rate was 0.61±0.09, 0.74±0.05 and the ilium angle rate was 0.66±0.08, 0.80±0.08 in groups A and B, respectively, showing significant differences between the two groups ( F=69.729, P=0.000; F=65.165, P=0.000). ROC curve analysis showed that the critical point of ilium height rate was 0.71 (area under ROC curve was 0.927, P=0.000), and the critical point of ilium angle rate was 0.75 (area under ROC curve was 0.965, P=0.000). Conclusion PELD is not recommended for patients with L 5, S 1 intervertebral disc herniation, when the ilium height rate is greater than 0.71 and/or the ilium angle rate is greater than 0.75. Other surgical plans such as transpedicular approach, transpedicular approach, or open surgery, should be recommended to reduce the risk of surgery and the pain of patients.

Abstract
Many studies have reported the good outcomes of percutaneous endoscopic lumbar discectomy (PELD) for the treatment of lumbar disc herniation (LDH). However, the majority of published studies on PELD showed an average hospital stay of 2 to 5 days. Thus, the purpose of this retrospective study was to evaluate and compare the clinical outcomes of patients undergoing PELD for LDH as day surgery with the outcomes of patients managed as inpatients.A total of 402 patients who underwent PELD for single-level LDH were included. The visual analog scale score (VAS) for leg and back pain, Oswestry Disability Index (ODI) score, and Macnab criteria were evaluated preoperatively and at 2 years postoperatively (final follow-up). Operation time, duration of hospital stay, cost, postoperative complications, and the rates of and reasons for delayed discharge and readmission were recorded and analyzed.The mean operative time was 45.8 ± 8.4 minutes in the PELD-A (nonday surgery mode) group and 41.3 ± 8.7 minutes in the PELD-D (day surgery mode) group (P = .63). The average duration of hospital stay was 2.8 ± 1.1 days in the PELD-A group and 3.2 ± 0.9 hours in the PELD-D group (P < .001). The average hospitalization expenses of the PELD-A and PELD-D groups were 28,090 ± 286 RMB and 24,356 ± 126 RMB (P = .03), respectively. In both groups, the mean VAS and ODI scores improved significantly postoperatively compared with the preoperative scores. The satisfactory result rate was 89.8% in the PELD-D group and 91.0% in the PELD-A group, without a significant difference (P = .68). The delayed discharge rate in the PELD-A and PELD-D groups was 8.20% and 8.43%, respectively (P = .93). The main reasons for delayed discharge were dysesthesia, neurologic deficit, nausea, headache and residential distance from the hospital. The overall readmission rates were 5.99% and 5.53% in the PELD-A and PELD-D groups, respectively (P = .85). The most common reasons for readmission were reherniation, sequestered herniation and pain.In conclusion, PELD is safe and effective for the treatment of LDH and can reduce medical costs as day surgery, and it thus warrants increased attention.

Abstract
People's understanding of lumbar spinal stenosis has become more and more comprehensive and reasonable, however, there are still many controversies about the concepts of "central lumbar canal" and "lateral lumbar spinal canal", and there is no unified standard at present. In this paper, we redefine and differentiate the two concepts. We believe that some kinds of central canal stenosis caused by bilateral recess stenosis can be completely solved by bilateral percutaneous endoscopic transforaminal discectomy. At the same time, the concept of "lumbar lateral recess" is ambiguous. We redefine it as "lateral lumbar spinal canal" and propose "West China Hospital classification" to guide surgical decision-making, which has been widely recognized and applied.

Percutaneous endoscopic transforaminal discectomy precedes interlaminar discectomy in the efficacy and safety for lumbar disc herniation. Biosci Rep 2019; 39:BSR20181866. [PMID: 30705086 PMCID: PMC6379230 DOI: 10.1042/bsr20181866] [Citation(s) in RCA: 16] [Impact Index Per Article: 3.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/15/2018] [Revised: 01/15/2019] [Accepted: 01/25/2019] [Indexed: 11/17/2022] Open
Abstract
We searched several databases from the times of their inception to 20 December 2018. Randomized controlled trials and cohort studies that compared percutaneous endoscopic transforaminal discectomy (PETD) with percutaneous endoscopic interlaminar discectomy (PEID) were identified. We used a random-effects model to calculate the relative risks (RRs) of, and standardized mean differences (SMDs) between the two techniques, with 95% confidence intervals (CIs). Twenty-six studies with 3294 patients were included in the final analysis. Compared with PEID, PETD reduced the short-term (SMD -0.68; 95% CI -1.01, -0.34; P=0.000) and long-term (SMD -0.47; 95% CI -0.82, -0.12; P=0.000) visual analog scale scores, blood loss (SMD -4.75; 95% CI -5.80, -3.71; P=0.000), duration of hospital stay (SMD -1.86; 95% CI -2.36, -1.37; P=0.000), and length of incision (SMD -3.93; 95% CI -5.23, -2.62; P=0.000). However, PEID was associated with a lower recurrence rate (P=0.035) and a shorter operative time (P=0.014). PETD and PEID afforded comparable excellent- and good-quality data, long- and short-term Oswestry disability index (ODI) scores, and complication rates. PETD treated lumbar disc herniation (LDH) more effectively than PEID. Although PETD required a longer operative time, PETD was as safe as PEID, and was associated with less blood loss, a shorter hospital stay, and a shorter incision. PETD is the best option for patients with LDH.

Abstract
A discal cyst is a rare lesion that causes low back pain and radiculopathy of the lower extremities. There are several reports of discal cysts occurring after surgery, but data are limited on their occurrence after percutaneous endoscopic discectomy (PED). A 21-year-old man with disc herniation at the L4-L5 disc level underwent PED via a transforaminal approach. The immediate postoperative course was uneventful and his symptoms were relieved. Six weeks after surgery, low back pain and mild pain in the left thigh recurred. Magnetic resonance imaging (MRI) revealed a cystic lesion adjacent to the left side of the L4-L5 intervertebral disc. Conservative treatment was ineffective, so we reoperated using PED with the same approach. Pain improved and MRI revealed disappearance of the cystic lesion. When symptoms relapse after PED, it is necessary to consider the occurrence of a cyst.

Abstract
Discal cyst has been recognized as a distinct cause of back pain and radiculopathy. The clinical features are similar to other pathologies as disc prolapse and stenosis. Various treatment modalities have been described, ranging from nerve blocks to surgical excision. There are scarce reports on the endoscopic appearance of discal cysts. The present paper based on two cases operated by transforaminal and interlaminar endoscopy at our institute demonstrates the explicit intraoperative view and different pathological components of discal cysts.

Abstract
RATIONALE The accurate and smooth establishment of a working cannula guarantees rapid and minimally invasive treatment effects using percutaneous endoscopic lumbar discectomy (PELD) for lumbar disc herniation (LDH). With anatomic variations such as a hyperplastic superior articular process (SAP), the conventional transforaminal approach cannot achieve an ideal result. PATIENT CONCERNS A 48-year-old male patient suffered waist and left lower limb pain, with exacerbation of symptoms after exertion. DIAGNOSES L5-S1 disc herniation, hyperplastic SAP of S1. INTERVENTIONS To demonstrate the segment responsible for compression, a lumbar nerve root block was carried out. This was followed by PELD via a transfacet joint approach at L5-S1. OUTCOMES The patient experienced an improved quality of life postoperatively (i.e., visual analog score for pain = 1 and Oswestry disability index = 88). Lumbar function and stability were preserved as of the 1-month postoperative follow-up. LESSONS The transfacet joint approach could extend the indications for PELD and present an alternative option in selected cases. A new concept of "subsidence foramen" is raised to characterize this anatomic variation, and it may guide working access establishment of PELD. In addition, reading imaging results carefully and individualizing treatments promote the use of PELD as minimally invasive surgery.

Abstract
Objective To evaluate the short-term effectiveness of percutaneous endoscopic lumbar discectomy (PELD) in treatment of buttock pain associated with lumbar disc herniation. Methods Between June 2015 and May 2016, 36 patients with buttock pain associated with lumbar disc herniation were treated with PELD. Of 36 cases, 26 were male and 10 were female, aged from 18 to 76 years (mean, 35.6 years). The disease duration ranged from 3 months to 10 years (mean, 14 months). The location of the pain was buttock in 2 cases, buttock and thigh in 6 cases, buttock and the ipsilateral lower extremity in 28 cases. Thirty-four patients had single-level lumbar disc herniation, and the involved segments were L 4, 5 in 15 cases and L 5, S 1 in 19 cases; 2 cases had lumbar disc herniation at both L 4, 5 and L 5, S 1. The preoperative visual analogue scale (VAS) score of buttock pain was 6.1±1.3. VAS score was used to evaluate the degree of buttock pain at 1 month, 3 months, 6 months, and last follow-up postoperatively. The clinical outcome was assessed by the modified MacNab criteria at last follow-up. Results All patients were successfully operated and the operation time was 27-91 minutes (mean, 51 minutes). There was no nerve root injury, dural tear, hematoma formation, or other serious complications. The hospitalization time was 3-8 days (mean, 5.3 days). All incisions healed well and no infection occurred. Patients were followed up 12-24 months (median, 16 months). MRI examination results showed that the dural sac and nerve root compression were sufficiently relieved at 3 months after operation. Patients obtained pain relief after operation. The postoperative VAS scores of buttock pain at 1 month, 3 months, 6 months, and last follow-up were 1.1±0.6, 0.9±0.3, 1.0±0.3, and 0.9±0.4 respectively, showing significant differences when compared with preoperative VAS scores ( P<0.05); there was no significant difference in VAS score between the different time points after operation ( P>0.05). At last follow-up, according to the modifed MacNab criteria, the results were excellent in 27 cases, good in 9 cases, and fair in 2 cases, and the excellent and good rate was 94.4%. Conclusion PELD can achieve satisfactory short-term results in the treatment of buttock pain associated with lumbar disc herniation and it is a safe and effective minimally invasive surgical technique.

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.

[PMID: 29042967 PMCID: PMC5639406 DOI: 10.3892/etm.2017.4929] [Citation(s) in RCA: 16] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/06/2017] [Accepted: 06/20/2017] [Indexed: 11/08/2022] Open
Abstract
We compared the clinical effects between the percutaneous endoscopic lumbar discectomy (PELD) and microendoscopic discectomy (MED) treatments for protrusion of lumbar intervertebral disc. We conducted a retrospective analysis on 60 patients who were diagnosed with single-segment protrusion of lumbar intervertebral disc during the period from January 2009 to June 2016. Patients were divided into two groups, the PELD and MED groups, which contained 30 cases each. We evaluated the operation results according to oswestry dysfunction index (ODI), visual analogue scale (VAS) and the improved MacNab standard. The average follow-up visit period after the operation was 18 months and the operation time of the two groups was not statistically different. The cadaverine quantity of bleeding in the PELD group is less than that in the MED group. Moreover, the average length of incision and the length of stay were shortened for the PELD group compared to the MED group. The ODI and VAS after operation for the two groups improved significantly compared to that before operation (P<0.05). The qualified rates of the PELD and MED groups were 93.0 and 90.0%, respectively, as of the improved MacNab method. The complication occurrence rates for the two groups during perioperative period were not different. Therefore, the short-term efficacy of the two minimally invasive operation methods (PELD and MED) on the treatment of protrusion of lumbar intervertebral disc is satisfactory. In cases where operation indications are chosen strictly, PELD can be regarded as a method of safety and efficiency due to the advantages of minimal incision, less bleeding, minimal trauma and faster postoperative recovery.

Abstract
The study was to comprehensively compare the postoperative outcome and imaging parameter characters in a short/middle period between the percutaneous endoscopic lumbar discectomy (PELD) and the internal fixation of bone graft fusion (the most common form is posterior lumbar interbody fusion [PLIF]) for the treatment of adjacent segment lumbar disc prolapse with stable retrolisthesis after a previous lumbar internal fixation surgery.In this retrospective case-control study, we collected the medical records from 11 patients who received PELD operation (defined as PELD group) for and from 13 patients who received the internal fixation of bone graft fusion of lumbar posterior vertebral lamina decompression (defined as control group) for the treatment of the lumbar disc prolapse combined with stable retrolisthesis at Department of Spine Surgery, the Third Hospital of Hebei Medical University (Shijiazhuang, China) from May 2010 to December 2015. The operation time, the bleeding volume of perioperation, and the rehabilitation days of postoperation were compared between 2 groups. Before and after surgery at different time points, ODI, VAS index, and imaging parameters (including Taillard index, inter-vertebral height, sagittal dislocation, and forward bending angle of lumbar vertebrae) were compared.The average operation time, the blooding volume, and the rehabilitation days of postoperation were significantly less in PELD than in control group. The ODI and VAS index in PELD group showed a significantly immediate improving on the same day after the surgery. However, Taillard index, intervertebral height, sagittal dislocation in control group showed an immediate improving after surgery, but no changes in PELD group till 12-month after surgery. The forward bending angle of lumbar vertebrae was significantly increased and decreased in PELD and in control group, respectively.PELD operation was superior in terms of operation time, bleeding volume, recovery period, and financial support, if compared with lumbar internal fixation operation. Radiographic parameters reflect lumber structure changes, which could be observed immediately after surgery in both methods; however, the recoveries on nerve function and pain relief required a longer time, especially after PLIF operation.

Abstract
Introduction Successful percutaneous endoscopic lumbar discectomy (PELD) requires an appropriate working trajectory. Due to the complexity of spinal anatomy, this is difficult to verify with conventional 2-dimensional fluoroscopy. Aim Here we assessed the feasibility and utility of the O-arm for establishing the working trajectory for PELD. Material and methods We retrospectively reviewed the records of 89 patients with lumbar disc herniation who underwent PELD using the O-arm. The working trajectory was evaluated with standard fluoroscopic images or 3-dimensional, volumetric computed tomography scan. Based on the detail provided by the multiplanar view, we confirmed the ideal working trajectory and adjusted the surgical approach accordingly. Results At the 12-month follow-up, based on MacNab's criteria, 85.9% of patients showed an excellent or good outcome. There were no major complications. Conclusions The O-arm provides detailed multiplanar intraoperative high-quality imaging for PELD, and enables the surgeon to ascertain the surgical anatomy, determine the optimal working trajectory, and improve the accuracy of surgery.

Abstract
Percutaneous endoscopic discectomy (PED) is a minimally invasive disc surgery that can be performed under local anesthesia and requires only an 8-mm skin incision. For transligamentous extruded nucleus pulposus with foraminal stenosis, it is very hard to remove the migrated mass with a simple transforaminal approach. For such difficult cases, foraminoplasty and an epiduroscopic technique is useful. A 29-year-old man visited the authors' hospital, complaining of low-back and right leg pain. MRI revealed a massive herniated nucleus pulposus with foraminal stenosis. A transforaminal PED was planned to remove the herniated mass. Through the inside-out technique, the base of the herniated mass was removed. Following the foraminoplasty, the cannula was moved into the epidural space. With epidural observation just beneath the nerve root, the extruded transligamentous fragment was confirmed and removed en bloc. Immediately after the surgery, the patient's symptoms resolved. The combination of foraminoplasty and epiduroscopic observation during the transforaminal approach for PED is a useful and reliable technique to remove extruded transligamentous disc fragments.

Abstract
A 64-year-old man was referred to the authors with low-back pain (LBP) and right leg pain with a history of previously diagnosed lumbar disc herniation (LDH) at L4-5. He had undergone 2 percutaneous endoscopic lumbar discectomies (PELDs) for the herniation at another institution, and according to the surgical record of the second surgery, a dural tear occurred intraoperatively but was not repaired. Postoperative conservative treatments such as an epidural block and blood patch had not relieved his persistent LBP or right leg pain. Upon referral to the authors, MRI and myelography revealed an intradural LDH. The herniated mass was removed by durotomy, and posterior lumbar interbody fusion was performed. His symptoms were partially improved after surgery. Primary suture is technically difficult when a dural tear occurs during PELD. Therefore, close attention should be paid to avoiding such tears, and surgeons should increase their awareness of intradural LDH as a possible postoperative complication of PELD.

Abstract
Background: Acute lumbar disc herniation can occur in every lumbar intervertebral disc space and in multiple levels simultaneously. In the cases of 2 levels adjacent lumbar disc herniations of severe unilateral radiculopathic leg pain caused by compression of the nerve roots, respectively, multiple incision or long incision is generally needed for simultaneous removal of disc fragment in 2 levels. Objectives: We proposed the minimally invasive one portal skin incision endoscopic discectomy is effective and safe method to treat 2 levels adjacent lumbar disc herniation. Materials and Methods: We have experimented total 8 cases of 2 levels adjacent lumbar disc herniation having unilateral radiculopathic pain respectively. All cases are 2 levels adjacent lumbar disc herniation. We have tried a percutaneous endoscopic transforaminal approach through minimal one portal skin incision and remove the two herniated disc materials in the adjacent levels. Results: The L2-L3 level was involved in 2 patients, L3-L4 level in 6 patients, while the L4-L5 level was involved in 7 patients, L5-S1 level in 1 patient. The mean follow-up was 18.5 months. The mean visual analogue score (VAS) of the patients prior to surgery was 7.75, and the mean postoperative VAS was 2.375. According to Macnab's criteria, 3 patients had excellent results, 4 patients had good results, 1 patient had fair results, and no patient had a poor result; satisfactory results were obtained in 87.5% of the cases. Conclusion: The percutaneous endoscopic transforaminal approach through 1 skin portal incision could be effective surgical method in unilateral adjacent 2 levels lumbar disc herniation.
