J Orthop Surg Res 2017; 12:162. [PMID: 29084558 PMCID: PMC5663029 DOI: 10.1186/s13018-017-0662-4] [Citation(s) in RCA: 17] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/24/2017] [Accepted: 10/19/2017] [Indexed: 12/29/2022] Open
Abstract
Background Percutaneous endoscopic laminar discectomy is a typical minimally invasive discectomy operation that is classified into the percutaneous endoscopic transforaminal discectomy and the percutaneous endoscopic interlaminar discectomy. Based on whether the surgeon chooses to deal with the ligamentum flavum under endoscope guidance, percutaneous endoscopic discectomy by the interlaminar approach can be performed with a full endoscope technique with the intermittent endoscope technique. To our knowledge, there is no study comparing these two techniques in regard to their surgical effects and advantages. Therefore, we conducted this study to compare the cost, safety, and efficacy between the intermittent endoscopy technique and full endoscopy technique of endoscopic interlaminar lumbar discectomy at the L5–S1 level. Methods From September 2014 to March 2015, a total of 126 patients with radiculopathy due to L5–S1 disc herniation who were treated by a full endoscopy technique (65 patients) or intermittent endoscopy technique (61 patients) were included. Relevant data, such as duration time of the operation, hospitalization expenses, postoperative bed rest time, length of hospitalization, and complication rates, were recorded. Clinical outcomes were assessed by the visual analog scale score, modified MacNab criteria, and Oswestry disability index. Results In the full endoscope (FE) group, the mean duration time of surgery was 75.0 ± 11.9 min. The postoperative bed rest time was 6.5 ± 1.1 h, length of hospitalization was 3.8 ± 1.1 days, and complication rate was 7.69%. In the intermittent endoscopy (IE) group, the mean duration time of surgery was 43.0 ± 16.4 min. The postoperative bed rest time was 5.0 ± 1.1 h, length of hospitalization was 3.6 ± 1.2 days, and complication rate was 6.60%. The average hospitalization expenses of the FE group and IE group, respectively, were 32,069 ± 1086 RMB and 22,665 ± 899 RMB. There were significant differences in the surgical duration and hospitalization expenses (P < 0.01), but no differences between the two groups in postoperative bed rest time, length of hospitalization, or complication rates (P > 0.05). The postoperative Oswestry disability index and VAS were clearly improved in both groups compared with those of preoperation (P < 0.01). These two procedures have the same clinical outcomes (P > 0.05). Conclusions Both the full endoscopy technique and intermittent endoscopy technique achieved good outcomes, whereas the intermittent endoscopy technique is a more effective option for a shorter duration surgery and lower hospitalization expenses.

Abstract
ABSTRACT Objective: Lumbar disc herniation is a common indication for surgical treatment of the spine. Open microdiscectomy is the gold standard. New surgical techniques have emerged, such as spinal endoscopy. We compared and evaluated two endoscopic techniques: the transforaminal and the interlaminar. Methods: Fifty-five patients underwent endoscopic technique and were assessed by VAS and ODI in the preoperative period, and in the first and sixth month after the procedure. Results: We had 89.1% of good results and 10.9% of complications. Conclusion: We conclude that endoscopic techniques are safe and effective for the surgical treatment of lumbar disc herniation.

Abstract
BACKGROUND Though different techniques have been successfully employed in the treatment of recurrent lumbar disc herniation, the one which should be considered most ideal has remained a controversy, particularly since there are currently no generally accepted guidelines for surgical care. OBJECTIVE To review previous publications comparing the available operative options, with the aim of determining if any of the available interventions gives better outcomes compared to others. METHODS A systematic literature review of previous publications comparing various techniques employed in the surgical treatment of recurrent disc herniation. RESULTS All publications investigated in this review clearly demonstrated quite comparable outcomes, with no superiority of one method over the other. CONCLUSION In view of the currently available data and evidence, minimally invasive techniques for revision of recurrent disc herniation do not really appear to be superior to the conventional open surgical approaches and vice-versa. We suggest the management strategy for surgical treatment of each case of recurrence to be simply based on the experience of the surgeon, the available facilities and equipment. Fusion should not be undertaken in all recurrences but should only be considered as an option for revision when spinal instability, spinal deformity or associated radiculopathy is present.

Abstract
The present study explored a method to reduce X-ray exposure dose and avoid targeted puncture complications in percutaneous transforaminal endoscopic lumbar discectomy (PTELD). A total of 66 patients with lumbar disc herniation were divided into two groups for a controlled study. In the experimental group, 31 patients were subjected to PTELD using a novel targeted puncture technique with application of a lumbar disc herniation target collimator. The remaining 35 patients in the control group were subjected to free-hand targeted puncture PTELD. The number of X-ray fluoroscopies performed intraoperatively, targeted puncture accuracy, visual analogue scale for surgical pain and Oswestry disability index of the two groups were statistically analyzed. The experimental and control groups exhibited a statistically significant difference in the number of X-ray fluoroscopies required during the procedure (P<0.01). The number of successful first targeted punctures was 27 (87.1%) in the experimental group and three (8.6%) in the control group, indicating that the puncture accuracy was higher in the experimental group than in the control group. As for the pain response to outer sleeve insertion (local anesthetic injection through the guide sleeve), the experimental group had 25 mild cases (80.6%), five moderate cases (16.1%) and one severe care (3.2%), whereas the control group had five mild cases (14.3%), 19 moderate cases (54.3%) and 11 severe cases (31.4%). These results demonstrated that the overall pain response of the experimental group was milder than that of control group. Due to a larger puncture deviation, the nerve root was touched by the puncture needle in 12 cases in the control group and resulted in one case of severe postoperative infection. In conclusion, the novel targeted puncture technique guided by a lumbar disc herniation target collimator outlined in the present study is able to markedly reduce X-ray exposure dose in PTELD and limit the surgical risk and pain experienced by patients. Mastering this novel puncture technique may aid those new to performing PTELD.

Abstract
Objective To evaluate the feasibility and safety of percutaneous endoscopic technique in the treatment of intraspinal cement leakage after percutaneous vertebroplasty (PVP). Methods Between May 2014 and March 2016, 5 patients with lower limb pain and spinal cord injury caused by intraspinal cement leakage after PVP, were treated with percutaneous endoscopic spinal decompression. Of 5 cases, 3 were male and 2 were female, aged from 65 to 83 years (mean, 74.4 years). The course of disease was 10-30 days (mean, 16.2 days). Imageological examinations confirmed the levels of cement leakage at T 12, L 1 in 3 cases, and at L 1, 2 in 2 cases; bilateral sides were involved in 1 case and unilateral side in 4 cases. Two patients had lower limb pain, whose visual analogue scale (VAS) were 8 and 7; 3 patients had lower extremities weakness, whose Japanese Orthopedic Association (JOA) 29 scores were 18, 20, and 19. According to American Spinal Injury Association (ASIA) impairment scale, neural function was rated as grade E in 2 cases and grade D in 3 cases. Results The operation time was 55-119 minutes (mean, 85.6 minutes), and the blood loss was 30-80 mL (mean, 48 mL). CT scan and three-dimensional (3D) reconstruction at 1 day after operation showed that cement leakage was removed in all patients. Five cases were followed up 6-21 months (mean, 12 months). In 2 patients with lower limb pain, and VAS score was significantly decreased to 2 at last follow-up. In 3 patients with lower extremities weakness, the muscle strength was improved progressively, and the JOA29 scores at last follow-up were 21, 23, and 22. Conclusion Percutaneous endoscopic technique for intraspinal cement leakage after PVP is safe, effective, and feasible.

Abstract
OBJECTIVES The purpose of this study was to systematically compare the effectiveness and safety of full-endoscopic discectomy (FED) and micro-endoscopic discectomy (MED) with open discectomy (OD) for the treatment of symptomatic lumbar disc herniation. METHODS Electronic searches were performed using six databases from their inception to February 2016, identifying all relevant randomized controlled trials and comparative observational studies comparing either FED or MED with OD. Data were extracted and analyzed according to predefined clinical endpoints. RESULTS Twenty three studies were selected for analysis, including 421 FED, 6914 MED, and 21,152 OD cases. No significant difference was found between FED and OD in regards to postoperative visual analog scale (VAS) leg pain scores (WMD 0.03, P=0.93). Similar results were obtained for MED vs OD (WMD 0.09, P=0.18). In terms of postoperative Oswestry disability index (ODI), both FED and MED were similar to OD (WMD -2.60, P=0.32 and WMD -1.00, P=0.21, respectively). FED had a significantly shorter operative duration compared to OD (54.6 vs 102.6min, P=0.0001). MED alone and endoscopic approaches overall (including MED and FED) demonstrated significantly lower estimated blood loss (44.3 vs 194.4mL, P=0.03 and 38.2 vs 203.5mL, respectively, both p<0.05). FED alone demonstrated a trend towards lower estimated blood loss in comparison to OD (3.3 vs 244.9mL, P=0.07). No difference was found in overall complications, recurrence or reoperation rates, dural tears, root injury, wound infections, and spondylodiscitis between FED vs OD, or MED vs OD. CONCLUSIONS Based on this meta-analysis, FED and MED appear to be safe and efficacious alternatives to traditional approaches, but these results require further investigation and validation by prospective randomized studies.

Abstract
OBJECTIVE Although minimally invasive spinal surgery has recently gained popularity, few nationwide studies have compared the adverse events that occur during endoscopic versus open spinal surgery. The purpose of this study was to compare perioperative complications associated with microendoscopic discectomy (MED) and open discectomy for patients with lumbar disc herniation. METHODS The authors retrospectively extracted from the Diagnosis Procedure Combination database, a national inpatient database in Japan, data for patients admitted between July 2010 and March 2013. Patients who underwent lumbar discectomy without fusion surgery were included in the analysis, and those with an urgent admission were excluded. The authors examined patient age, sex, Charlson Comorbidity Index, body mass index, smoking status, blood transfusion, duration of anesthesia, type of hospital, and hospital volume (number of patients undergoing discectomy at each hospital). One-to-one propensity score matching between the MED and open discectomy groups was performed to compare the proportions of in-hospital deaths, surgical site infections (SSIs), and major complications, including stroke, acute coronary events, pulmonary embolism, respiratory complications, urinary tract infection, and sepsis. The authors also compared the hospital length of stay between the 2 groups. RESULTS A total of 26,612 patients were identified in the database. The mean age was 49.6 years (SD 17.7 years). Among all patients, 17,406 (65.4%) were male and 6422 (24.1%) underwent MED. A propensity score-matched analysis with 6040 pairs of patients showed significant decreases in the occurrence of major complications (0.8% vs 1.3%, p = 0.01) and SSI (0.1% vs 0.2%, p = 0.02) in patients treated with MED compared with those who underwent open discectomy. Overall, MED was associated with significantly lower risks of major complications (OR 0.62, 95% CI 0.43-0.89, p = 0.01) and SSI (OR 0.29, 95% CI 0.09-0.87, p = 0.03) than open discectomy. There was a significant difference in length of hospital stay (11 vs 15 days, p < 0.001) between the groups. There was no significant difference in in-hospital mortality between MED and open discectomy. CONCLUSIONS The microendoscopic technique was associated with lower risks for SSI and major complications following discectomy in patients with lumbar disc herniation.

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
STUDY DESIGN A prospective, randomized controlled study of patients with L5-S1 lumbar disc herniations, operated with endoscopic discectomy through an interlaminar or transforaminal approach. OBJECTIVE To compare the results of percutaneous endoscopic lumbar discectomy in L5-S1 disc herniation through an interlaminar or transforaminal approach. SUMMARY OF BACKGROUND DATA The transforaminal and interlaminar techniques are both acceptable approaches for L5-S1 disc herniation. This is the first study to compare these two approaches in terms of their surgical effects and advantages. METHODS From January 2010 to June 2010, 60 patients with L5-S1 disc herniation were randomly recruited into two groups; one group underwent percutaneous endoscopic interlaminar discectomy (PEID) and the other group underwent percutaneous endoscopic transforaminal discectomy (PETD). There were 30 patients in each group. The operation time, intraoperative radiation time, postoperative bed rest time, hospitalization time, and complications were compared between the groups. The surgical effectiveness was assessed according to the Oswestry Disability Index (ODI), Visual Analog Scale (VAS), and modified MacNab criteria. RESULTS All the patients completed follow up with a mean of 27.6 months (range, 24-37 months). In the PEID group, the mean operation time was 65.0 ± 14.9 minutes, and the intraoperative radiation time was 0.60 ± 0.24 seconds. For the PETD group, the mean operation time was 86.0 ± 15.4 minutes, and the intraoperative radiation time was 6.50 ± 1.52 seconds. There were significant differences in operation time and radiation time between the two groups (P < 0.01) but not in the postoperative bed rest time, hospitalization time, or complication rate (P > 0.05). The postoperative ODI and VAS were obviously improved in both groups when compared with preoperation (P < 0.01). According to the MacNab criteria, the satisfactory rates were 93.3% and 90.0% in the two groups, without a significant difference (P > 0.05). CONCLUSION PEID can escape the blockade of crista iliaca, and advantages include a faster puncture orientation, a shorter operation time, and less intraoperative radiation exposure. PETD requires higher punctuation skill and more intraoperative radiation exposure. LEVEL OF EVIDENCE 4.

INDICATIONS Conservative treatment did not sufficiently improve clinical symptoms. This is true for progressive or persisting neurological deficits, as well as for persisting pain which alters the quality of the patient`s life. Results of surgery are strongly dependent on the preoperative duration of symptoms. Paramount is the "timing" of surgery: poorer surgical results associated with increasing preoperative duration of symptoms. CONTRAINDICATIONS Conservative treatment modalities have not been exhausted. SURGICAL TECHNIQUES There are 2 technologies (endoscopic/microsurgical) and 5 different approach strategies (endoscopic: interlaminar, transforaminal; microsurgical: interlaminar, translaminar, extraforaminal), whereby the choice is determined by morphology and location of the herniated disc. All techniques are minimally invasive and lead to comparable clinical results. POSTOPERATIVE MANAGEMENT For all techniques, patients are mobilized early. Light sports activities allowed after 2 weeks and return to work after about 4 weeks. RESULTS Good clinical outcomes in meta-analyses/large case series are between 80-95 %.

Abstract
STUDY DESIGN Technical report. OBJECTIVE To present a detailed surgical technique for percutaneous endoscopic interlaminar discectomy (PEID) for highly migrated disk herniation. SUMMARY OF BACKGROUND DATA Percutaneous lumbar endoscopic discectomy for highly migrated disk herniation is still challenging even for an experienced surgeon. Because of the risk of failure and technical difficulty, open discectomy is recommended for a high-grade migration. However, past reports focused on the transforaminal approach (percutaneous endoscopic transforaminal discectomy) and may give a biased impression. We may overlook the merit of PEID. The surgical procedure for PEID is similar to a traditional open discectomy and the range of approach could be widened by the inclined introduction and pivoting motion of an endoscope. METHODS Eighteen consecutive patients (M:F=12:6; age, 56±15 y) with highly migrated disk herniation were enrolled for the present study. The disk material was migrated superiorly in 7 patients (L4-5, 4; L5-S1, 2; L2-3, 1) and inferiorly in 11 patients (L4-5, 6; L3-4, 4; L5-S1, 1). PEID was applied in 17 patients and PETD was performed for L2-3 disk herniation. The follow-up period was 16±12 months. The outcome was graded using the MacNab criteria. RESULTS Complete removal of the disk material was confirmed with magnetic resonance imaging in 16 patients (success rate 89%). Revision operation was necessary in 2 patients with inferior migration from L4-5. The residual disk was removed through the L5-S1 laminar window 2 days after surgery with excellent outcome at the last follow-up. The outcome at the last follow-up was excellent in 12 patients, good in 3, fair in 2, and poor in 1. Dural tear was suspected in 1 patient without any further problems and there was no recurrence during follow-up. CONCLUSIONS PEID may be applied comfortably even for less-experienced surgeons because of the familiar anatomy with open surgery.

Abstract
Minimally invasive percutaneous endoscopic discectomy (PED) with a transforaminal approach under local anesthesia was started in the late 20th century. As the procedure requires a skin incision of only 8 mm, it is the least invasive disc surgery procedure at present, and owing to advances in instruments and optics, the use of this technique has gradually spread. In Japan, Dr. Dezawa from Teikyo University Mizonokuchi Hospital introduced this technique in 2003. Thanks to his efforts, the number of surgeons who can perform PED has increased, although the number of active PED surgeons is still only around 20. The first author (K.S.) started PED in 2010. In this review article, we explain the state-of-the-art PED transforaminal technique for minimally invasive disc surgery and present three successful cases.

Abstract
BACKGROUND Lumbar disc herniations at the L1-L2 and L2-L3 levels have unique characteristics that result in worse surgical outcomes after traditional microdiscectomy compared with herniation at L3-L4. The purpose of this study was to evaluate the characteristics, clinical presentation, and outcomes of patients who underwent percutaneous endoscopic lumbar discectomy (PELD) at L1-L2 and L2-L3, compared with those who underwent PELD at L3-L4. METHODS We retrospectively evaluated the clinical data from 55 patients who underwent PELD for single-level lumbar disc herniation between 2008 and 2014, at a mean follow-up of 29.9 ± 16.4 months (12-month minimum; effective rate, 89.1%). Surgical duration; length of postoperative hospital stay; hospitalization cost; recurrence rate; Macnab criteria assessment; visual analog scale (VAS) of back pain, leg pain, and numbness; Japanese Orthopedic Association (JOA) low back pain score; and Oswestry Disability Index (ODI) before and after surgery were evaluated. RESULTS In the L1-L3 group, 76.9% of the patients had a positive femoral stretch test, compared with only 42.8% of those in the L3-L4 group (P < 0.05). Of the 49 patients with adequate follow-up, 17 (34.7%) exhibited excellent improvement, 23 (46.9%) had good improvement, and 6 (12.2%) had fair improvement according to the Macnab criteria. The VAS scores for back pain, leg pain, and numbness decreased significantly postoperatively in both groups, as did all other outcome measures (P < 0.05). CONCLUSIONS PELD is a safe and effective treatment for upper lumbar disc herniation and may compare favorably with the same procedure for lower lumbar disc herniation. In addition, the positive femoral stretch test was a relatively good diagnostic method for disc herniation at L1-L2 and L2-L3, compared with herniation at L3-L4.

Abstract
Study Design Retrospective. Purpose To report the outcomes of patients with lumbar spinal stenosis treated with percutaneous endoscopic decompression, focusing on the results of clinical evaluations. Overview of Literature There are no studies about two portal percutaneous endoscopic decompression in the treatment of lumbar spinal stenosis. Methods Medical and surgical complications were examined and clinical results were analyzed for 30 patients who consecutively underwent two portal percutaneous endoscopic decompression for lumbar spinal stenosis were reviewed. The operations were performed by unilateral laminotomy for bilateral decompression. Results All patients displayed clinical improvement when were evaluated with visual analog scale (VAS) score of pain, Oswestry disability index (ODI) and Macnab criteria. The improvement of VAS and ODI was 8.3±0.7 to 2.3±2.6 and 65.2±13.7 to 24.0±15.5, respectively (both p<0.05). Complications were the same as for open decompression. The most common complication was transient nerve root paresthesia. Conclusions Surgical decompression with two portal percutaneous endoscopic decompression has initial benefits, but long-term studies should pay more attention to the risks of postoperative instability and restenosis as well as the need for re-operation. Further investigations with long-term results are thus required.

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
STUDY DESIGN A systematic review. OBJECTIVE To systematically review the previous literature regarding revision surgery for real recurrent lumbar disk herniation. SUMMARY OF BACKGROUND DATA "Real" recurrent lumbar disk herniation means the presence of herniated disk material at the same level and side as the primary disk herniation. If conservative treatment fails, revision surgery, a major concern, is indicated. It is important for both patients and spine surgeons to understand epidemiology trends and outcomes of revision surgery for real recurrent lumbar disk herniation (real-RLDH). METHODS The electronic databases PubMed, the Cochrane library, and EMBASE were queried for English articles regarding revision surgery for real-RLDH, published between January 1980 and May 2014. The incidence, interval between primary and revision surgery, risk factors, surgery type, complications, and clinical outcomes of revision surgery for real-RLDH were summarized. RESULTS The reported incidence of revision surgery, specifically for real-RLDH, lies between 1.4% and 11.4%. The complication rate is reported between 0% and 34.6%, with dural tear being the most common complication. Previous studies revealed that satisfactory or successful clinical outcome was achieved in 60%-100% of patients after revision surgery for real-RLDH. Several studies reported similar clinical outcomes between primary and revision surgery. CONCLUSIONS The incidence of revision surgery for real-RLDH is relatively low. It is essential to pay careful attention to prevent a dural tear. Patients may expect clinical outcomes similar to those following primary discectomy.

Abstract
Discectomy for lumbar disc provides faster relief in acute attack than does conservative management. Long-term results of open, microscopy-, and endoscopy-assisted discectomy are same. Early results of endoscopy-assisted surgery are better as compared to that of open surgery in terms of better visualization, smaller incision, reduced hospital stay, better education, lower cost, less pain, early return to work, and rehabilitation. Although microscopic discectomy also has comparable advantages, endoscopic-assisted technique better addresses opposite side pathology. Inter laminar technique (ILT) and trans foraminal technique (TFT) are two main endoscopic approaches for lumbar pathologies. Endoscopy-assisted ILT can be performed in recurrent, migrated, and calcified discs. All lumbar levels including L5-S1 level, intracanalicular, foraminal disc, lumbar canal and lateral recess stenosis, multiple levels, and bilateral lesions can be managed by ILT. Migrated, calcified discs, L5-S1 pathology, lumbar canal, and lateral recess stenosis can be better approached by ILT than by TFT. Most spinal surgeons are familiar with anatomy of ILT. It can be safely performed in foramen stenosis and in uncooperative and anxious patients. There is less risk of exiting nerve root damage, especially in short pedicles and in presence of facet osteophytes as compared to TFT. On the other hand, ILT is more invasive than TFT with more chances of perforations of the dura matter, pseudomeningocele formation, and cerebrospinal fluid fistula in early learning curve. Obtaining microsurgical experience, attending workshops, and suitable patient selection can help shorten the learning curve. Once adequate skill is acquired, this procedure is safe and effective. The surgeon must be prepared to convert to an open procedure, especially in early learning curve. Spinal endoscopy is likely to achieve more roles in future. Endoscopy-assisted ILT is a safer alternative to the microscopic technique.

Abstract
OBJECT
The aim of the study was to investigate the safety and efficacy of minimally invasive tubular microdiscectomy for the treatment of recurrent lumbar disc herniation (LDH). As opposed to endoscopic techniques, namely microendoscopic and endoscopic transforaminal discectomy, this microscopically assisted technique has never been used for the treatment of recurrent LDH.
METHODS
Thirty consecutive patients who underwent minimally invasive tubular microdiscectomy for recurrent LDH were included in the study. The preoperative and postoperative visual analog scale (VAS) scores for pain, the clinical outcome according to modified Macnab criteria, and complications were analyzed retrospectively. The minimum follow-up was 1.5 years. Student t-test with paired samples was used for the statistical comparison of pre- and postoperative VAS scores. A p value < 0.05 was considered to be statistically significant.
RESULTS
The mean operating time was 90 ± 35 minutes. The VAS score for leg pain was significantly reduced from 5.9 ± 2.1 preoperatively to 1.7 ± 1.3 postoperatively (p < 0.001). The overall success rate (excellent or good outcome according to Macnab criteria) was 90%. Incidental durotomy occurred in 5 patients (16.7%) without neurological consequences, CSF fistula, or negative influence to the clinical outcome. Instability occurred in 2 patients (6.7%).
CONCLUSIONS
The clinical outcome of minimally invasive tubular microdiscectomy is comparable to the reported success rates of other minimally invasive techniques. The dural tear rate is not associated to higher morbidity or worse outcome. The technique is an equally effective and safe treatment option for recurrent LDH.

Abstract
Endoscopic disc surgery (EDS) for lumbar spine disc herniation is a well-known but developing field, which is increasingly spreading in the last few years. Rate of recurrence/residual, complications, and outcomes, in comparison with standard microdiscectomy (MD), is still debated and need further data. We performed an extensive review based on the last 6 years of surgical series, systematic reviews, and meta-analyses reported in international, English-written literature. Articles regarding patients treated through endoscopic transforaminal or interlaminar approaches for microdiscectomy (MD) were included in the present review. Papers focused on endoscopic surgery for other spinal diseases were not included. From July 2009 to July 2015, we identified 51 surgical series, 5 systematic reviews, and one meta-analysis reported. In lumbar EDS, rate of complications, length of hospital staying, return to daily activities, and overall patients' satisfaction seem comparable to standard MD. Rate of recurrence/residual seems higher in EDS, although data are nonhomogeneous among different series. Surgical indication and experience of the performing surgeon are crucial factors affecting the outcome. There is growing but still weak evidence that lumbar EDS is a valid and safe alternative to standard open microdiscectomy. Statistically reliable data obtained from randomized controlled trials (better if multicentric) are desirable to further confirm these results.

Abstract
INTRODUCTION The full endoscopic interlaminar approach (FEILA) is a minimally invasive procedure to treat intracanal lumbar disc herniation not approachable by endoscopic transforaminal access. Disc prolapses have been classified into three categories according to their position and passing nerve root displacement: (i) type A, in which the nerve root is displaced medially; (ii) type B, in which the nerve root is displaced laterally; and (iii) type C, in which the nerve root is ventrally displaced. We focused on the FEILA technique because it was likely to involve few complications and that provided the advantages of the endoscopic approach. METHODS We prospectively evaluated 100 consecutive cases of L5-S1 disc herniations operated on with FEILA, including 85 type A cases, 13 type B, and 2 type C. Patients were evaluated at discharge, 3 months, 6 months and 2 years. RESULTS The operating time varied from 15 to 40 min. The use of drills and burrs was necessary to treat type B disc herniations; thus, it was preferable that these cases were operated on later in the learning curve. After surgery, 90% of neurological deficits improved. The Oswestry Disability Index and visual analog scale leg at last follow-up were 15 and 9, respectively. There were no major complications. There were five cases of recurrence; four of which were treated with same technique and with good results. CONCLUSION FEILA is a safe procedure for the removal of intracanal L5-S1 disc herniations. The late follow-up confirms the stability of the results. We suggest treating type A prolapse at the beginning of the learning curve and type B herniations after sufficient experience in the use of the burrs has been achieved.

Abstract
We aim to identify factors predicting patient dissatisfaction 2 years after discectomy for lumbar disc herniation (LDH) in a Chinese older cohort. Preoperative and 2-year follow-up data for 843 patients were analyzed. After 2 years of discectomy, the patients rated their satisfaction by Patient Satisfaction Index (PSI), with response of 1 or 2 defining satisfaction and a PSI response of 3 or 4 defining dissatisfaction. Associations between perioperative variables and satisfaction with the results of surgery were examined in univariate and multivariate analysis. Six hundred fifty-seven patients had a PSI of 1 or 2 and were enrolled as satisfied group, 186 patients had a PSI of 3 or 4 and were enrolled as dissatisfied group. At baseline, no significant differences were found between the 2 groups in age, occupation, Oswestry Disability Index (ODI), Visual Analog Scale (VAS)-leg, and VAS-back. Compared to satisfied group, dissatisfied group had a significantly higher BMI and a higher incidence of depression. Two years after discectomy, no significant differences were found between the 2 groups in decrease of ODI, decrease of VAS-back, decrease of VAS-leg, surgery complications. Compared to satisfied group, dissatisfied group experienced higher incidence of symptom recurrence and depression. Logistic regression analysis showed that obesity, pre- and postoperative depression, symptom recurrence were independently associated with patient dissatisfaction 2 years after discectomy.I n conclusion, more than 70% patients expressed satisfaction with discectomy for LDH. Two factors could predict patient dissatisfaction and be assessed before surgery: obesity and preoperative depression. Symptom recurrence and postoperative depression are also associated with diminished patient satisfaction.

Although minimally invasive full-endoscopic (FE) spine surgery through the interlaminar approach has proved safe and effective for surgical treatment of lumbar disk herniation, the learning curve of the procedure has not been sufficiently established. The purpose of this study is to determine the learning curve for the FE surgery through interlaminar approach for treating the L5/S1 disk herniation. Thirty-six patients with lumbar disk herniation (L5/S1 segment) who underwent FE lumbar discectomy through the interlaminar approach between March 2011 and March 2012 were equally divided into Group A, B, and C by the study time of the surgeons. Clinical evaluation data included perioperative parameters (operative duration, intraoperative blood loss, and the amount of intraoperative bone and ligament excision), clinical curative effect index [visual analog scale (VAS) score for leg and back pain], complications, and the rate of conversion to open surgery. The operation duration, intraoperative bleeding, and the amount of bone and ligament excision were gradually and significantly reduced in the Groups A, B, and C (P < 0.01) and reflected in steep curves of proficiency suggesting that the rate of learning was fast. The VAS scores of leg and back pain were significantly improved (P < 0.01) and no symptomatic recurrence was noticed during the follow-up period (1-1.5 years). The outcomes the three groups were not significantly different. The clinical outcomes of the minimally invasive surgery for the treatment of L5/S1 segment disk herniation through the interlaminar approach were excellent suggesting of a satisfactory curative effect. The steep learning curves of perioperative parameters plotted against the number of surgeries conducted suggest that proficiency can be reached reasonably fast.

Abstract
STUDY DESIGN A retrospective analysis. OBJECTIVE To present the surgical outcome of percutaneous endoscopic discectomy (PED) for recurrent herniated intervertebral disk disease (HIVD) and to suggest a surgical strategy. SUMMARY OF BACKGROUND DATA Revision discectomy is technically demanding because of the scar tissue, unclear anatomic planes, and retraumatization to the posterior structures. Although open microdiscectomy is a standard method, endoscopic techniques have emerged as a surgical alternative with comparable results. PED was performed with either the transforaminal (PETD) or the interlaminar approach (PEID). Previous reports have shown the surgical outcomes of PETD or PEID for recurrent HIVD, but the application of each approach was not addressed clearly. METHODS Consecutive 26 patients (M:F=16:10, mean age 53.1±12.4 y), who underwent PED for recurrent HIVD, were enrolled. The previous operation was an open discectomy in 22, a PETD in 2, and a PEID in 2 patients. PETD was considered preferentially, if it was feasible (n=11), because of the scar tissue formed by the previous operation. PEID was chosen (n=15) because of a high iliac crest (8), high canal compromise (3), high-grade inferior migration (2), and narrow neural foramen (2). All patients were followed up for 19.3±11.3 months. RESULTS In all patients, the recurrent disk material was removed successfully, and conversion to an open surgery was not necessary. Postoperative magnetic resonance imaging revealed that the ruptured disk was removed successfully in all cases. A favorable outcome (excellent or good outcome by MacNab's criteria) was achieved in 21 patients (81%). Re-recurrence occurred in 2 patients at 6 and 12 months postoperatively. Risk factors for an unfavorable outcome were not found in the present study (P>0.05). CONCLUSIONS The relevant utilization of updated surgical techniques may be helpful in overcoming the difficulty of revision surgery.

Reoperation rates after anterior cervical discectomy and fusion versus posterior cervical foraminotomy: a propensity-matched analysis. Spine J 2015; 15:1277-83. [PMID: 25720729 DOI: 10.1016/j.spinee.2015.02.026] [Citation(s) in RCA: 57] [Impact Index Per Article: 6.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/03/2014] [Revised: 02/03/2015] [Accepted: 02/18/2015] [Indexed: 02/03/2023]
Abstract
BACKGROUND CONTEXT Anterior cervical discectomy and fusion (ACDF) and posterior cervical foraminotomy (PCF) are both used to surgically treat patients with cervical radiculopathy and have been shown to have similar outcomes. Nonetheless, ACDF has become increasingly more commonplace compared with PCF, in part because of a pervasive belief that PCF has a higher incidence of required reoperations. PURPOSE To determine the reoperation rate at the index level of ACDF versus PCF 2 years postoperatively. STUDY DESIGN A retrospective case-control. PATIENT SAMPLE All patients that underwent ACDF and PCF for radiculopathy (excluding myelopathy indications) between January 2005 and December 2011. OUTCOME MEASURES Revision surgery within 2 years, at the index level, was recorded. METHODS Propensity score analysis between the ACDF and PCF groups was done, matching for age, gender, race, body mass index, tobacco use, median income and insurance status, primary surgeon, level of surgery, surgery duration, and length of hospital stay. RESULTS Seven hundred ninety patients met the inclusion/exclusion criteria, including 627 ACDF and 163 PCF. Before propensity matching, the PCF group was found to be significantly older and more likely to be male. After matching, there were no significant differences between groups for any baseline characteristics. Reoperation rate at the index level was 4.8% for the ACDF group and 6.4% for the PCF group (p=.7) within 2 years of the initial surgery. Using equivalence testing, based on an a priori null hypothesis that a clinically meaningful difference between the two groups would be ≥5%, we found that the absolute difference of 1.6% was significantly (p=.01) less than our hypothesized difference. CONCLUSIONS This study demonstrates that even after accounting for patient demographics, operative characteristics, and primary surgeon, there are no significant differences in 2-year reoperation rates at the index level between ACDF and PCF. The reoperation rates are statistically equivalent. Thus, spine surgeons can operate via the posterior approach without putting patients at increased risk for revision surgery at the index level.

Abstract
Advancements in both surgical instrumentation and full endoscopic spine techniques have resulted in positive clinical outcomes in the treatment of cervical, thoracic, and lumbar spine pathologies. Endoscopic techniques impart minimal approach related disruption of non-pathologic spinal anatomy and function while concurrently maximizing functional visualization and correction of pathological tissues. An advanced understanding of the applicable functional neuroanatomy, in particular the neuroforamen, is essential for successful outcomes. Additionally, an understanding of the varying types of disc prolapse pathology in relation to the neuroforamen will result in more optimal surgical outcomes. Indications for lumbar endoscopic spine surgery include disc herniations, spinal stenosis, infections, medial branch rhizotomy, and interbody fusion. Limitations are based on both non spine and spine related findings. A high riding iliac wing, a more posteriorly located retroperitoneal cavity, an overly distal or proximally migrated herniated disc are all relative contra-indications to lumbar endoscopic spinal surgery techniques. Modifications in scope size and visual field of view angulation have enabled both anterior and posterior cervical decompression. Endoscopic burrs, electrocautery, and focused laser technology allow for the least invasive spinal surgical techniques in all age groups and across varying body habitus. Complications include among others, dural tears, dysesthsia, nerve injury, and infection.

Abstract
PURPOSE The purpose of this study was to systematically compare the effectiveness and safety of endoscopic discectomy (ED) with open discectomy (OD) for the treatment of symptomatic lumbar disc herniation (LDH). METHODS A highly sensitive search strategy was used to identify all published randomized controlled trials up to August 2014. A criteria list taken from Koes et al. was used to evaluate the risk of bias of the included studies. The five questions that were recommended by the Cochrane Back Review Group were used to evaluate the clinical relevance. Cochrane methodology was used for the results of this meta-analysis. RESULTS Nine relevant RCTs involving 1,092 patients were identified. Compared with OD, ED results in slightly better clinical outcomes which were evaluated by the Macnab criteria without clinical significance (ED group: 95.76 %; OD group: 80 %; OR: 3.72, 95 % CI: [0.76, 18.14], P = 0.10), a significantly greater patient satisfaction rate (ED group: 93.21 %; OD group: 86.57 %; OR: 2.19; 95 % CI: [1.09, 4.40]; P = 0.03), lower intraoperative blood loss volume (WMD: -123.71, 95 % CI: [-173.47, -73.95], P < 0.00001), and shorter length of hospital stay (WMD: -Table 2144.45, 95 % CI: [-239.54, -49.37], P = 0.003). CONCLUSIONS From the existing outcomes, ED surgery could be viewed as a sufficient and safe supplementation and alternative to standard open discectomy. The cost-effectiveness analyses still remain unproved from the existing data. More independent high-quality RCTs using sufficiently large sample sizes with cost-effectiveness analyses are needed.

Abstract
BACKGROUND Surgery for same level multi-focal extruded lumbar disc herniations is technically challenging and the optimal method controversial. The subarticular disc herniation may pose the most challenging subtype requiring partial or complete facetectomy with or without fusion. The far-lateral disc herniation, often treated using a Wiltse approach, can also be difficult to access especially in the obese patient. When both the subarticular and far-lateral subtypes are simultaneously present at the same level with or without a paracentral disc herniation, a total facetectomy and interbody fusion (TLIF) or a total disc replacement (TDR) may be necessary. Endoscopic surgical techniques may reduce the need for these more invasive methods. METHODS Fifteen patients (6 male and 9 female) who had same level multi-focal (subarticular as well as far-lateral and/or paracentral) extruded disc herniations underwent single incision unilateral endoscopic disc excision by the same surgeon at a single institution. Patients were prospectively followed for an average of 15.3 months (range 14-18 months) and outcomes were evaluated radiographically and clinically (Visual Analogue Scale (VAS) and Oswestry Disability Index (ODI). RESULTS The mean operative time was 52 minutes with minimal blood loss in all cases. Fourteen of the 15 patients were discharged to home on the day of their surgery. The mean ODI and leg VAS scores improved from 22.9 ± 3.2 to 12.9 ± 2.7 (p < 0.005), and from 8.6 ± 1.6 to 2.1 + 0.4 (p < 0.005), respectively. CONCLUSIONS After an average of 15.3 months of follow-up, the clinical and radiographic results of full endoscopic surgical treatment of single level multi-focal (subarticular as well as far-lateral and/or paracentral) disc herniations are excellent. This study is a case series with mid-term follow-up (Level IV). CLINICAL RELEVANCE Foraminal and extra-foraminal full endoscopic decompression appears to offer a safe minimally invasive solution to a complex pathologic problem.

Abstract
Background Conventional diagnosis between axial and foraminal stenosis is suboptimal and long-term outcomes limited to posterior decompression. Aware state Transforaminal Endoscopic Lumbar Decompression and Foraminoplasty (TELDF) offers a direct aware state means of localizing and treating neuro-claudicant back pain, referred pain and weakness associated with stenosis failing to respond to conventional rehabilitation, pain management or surgery. This prospective survivability study examines the outcomes 10 years after TELDF in patients with foraminal stenosis arising from degeneration or failed back surgery. Methods For 10 years prospective data were collected on 114 consecutive patients with multilevel spondylosis and neuro-claudicant back pain, referred pain and weakness with or without failed back surgery whose symptoms had failed to respond to conventional rehabilitation and pain management and who underwent TELDF. The level responsible for the predominant presenting symptoms of foraminal stenosis, determined on clinical grounds, MRI and or CT scans, was confirmed by transforaminal probing and discography. Patients underwent TELDF at the spinal segment at which the predominant presenting symptoms were reproduced. Those that required treatment at an additional segment were excluded. Outcomes were assessed by postal questionnaire with failures being examined by the independent authors using the Visual Analogue Pain Scale (VAPS), the Oswestry Disability Index (ODI) and the Prolo Activity Score. Results Cohort integrity was 69%. 79 patients were available for evaluation after removal of the deceased (12), untraceable (17) and decliners (6) from the cohort. VAP scores improved from a pre-operative mean of 7.3 to 2.4 at year 10. The ODI improved from a mean of 58.5 at baseline to 17.5 at year 10. 72% of reviewed patients fulfilled the definition of an “Excellent” or “Good Clinical Impact” at review using the Spinal Foundation Outcome Score. Based on the Prolo scale, 61 patients (77%) were able to return and continue in full or part-time work or retirement activity post-TELDF. Complications of TELDF were limited to transient nerve irritation, which affected 19% of the cohort for 2 – 4 weeks. TELDF was equally beneficial in those with failed back surgery. Conclusions TELDF is a beneficial intervention for the long-term treatment of severely disabled patients with neuro-claudicant symptoms arising from spinal or foraminal stenosis with a dural diameter of more than 3mm, who have failed to respond to conventional rehabilitation or chronic pain management. It results in considerable improvements in symptoms and function sustained 10 years later despite co-morbidity, ageing or the presence of failed back surgery. Clinical Relevance The long term outcome of TELDF in severely disabled patients with neuro-claudicant symptoms arising from foraminal stenosis which had failed to respond to conventional rehabilitation, surgery or chronic pain management suggests that foraminal pathology is a major cause of lumbar axial and referred pain and that TELDF should be offered as primary treatment for these conditions even in the elderly and infirm. The application of TELDF at multiple levels may further widen the benefits of this technique.

Abstract
Surgical management of back and leg pain is evolving and changing due to a better understanding of the patho-anatomy well correlated with its pathophysiology. Pain is better understood with in vivo visualization and probing of the pain generators using an endoscopic access rather than just relying on symptoms diagram and image correlation. This has resulted in a shared decision making involving patient and surgeon, focused on a broader spectrum of surgical as well as non-surgical treatments, and not just masking the pain generator. It has moved away from decisions based on diagnostic images alone, that, while noting the image alterations, cannot explain the pain experienced by each individual as images do not always show variations in nerve supply and patho-anatomy. The ability to isolate and visualize "pain" generators in the foramen and treating persistent pain by visualizing inflammation and compression of nerves, serves as the basis for transforaminal endoscopic (TFE) surgery. This has also resulted in better pre surgical planning with more specific and defined goals in mind. The "Inside out" philosophy of TFE surgery is safe and precise. It provides basic access to the disc and foramen to cover a large spectrum of painful pathologies.

Abstract
The neurointerventional transforaminal endoscopic approach to sequestered disk herniation is a minimally invasive alternative to established microsurgical techniques. In addition to those techniques approaching the nucleus like APLD, the transforaminal approach allows the removal of dislocated sequesters in the epidural space. The main steps of the procedure are fluoroscopy-guided, so a good experience with fluoroscopy based interventional techniques is helpful, but the technique has a significant learning curve. If familiar with the different steps, it allows nearly every lumbar disk herniation to be treated with a very short hospital stay and short rehabilitation time. The paper describes in detail the steps of the procedure, the difficulties and advantages and gives a short review of the relevant literature.

Abstract
This study investigated the safety, effectiveness, and clinical and radiological outcomes of transforaminal lumbar interbody fusion (TLIF) for recurrent lumbar disc herniation (rLDH) following previous lumbar spine surgery. Seventy-three consecutive patients treated for rLDH between June 2005 and May 2012 were included in the study. The previous surgical procedures included percutaneous discectomy, discectomy with laminotomy, discectomy with unilateral laminectomy, and discectomy with bilateral laminectomy. The level of rLDH was L4-L5 in 51 patients, L5-S1 in 19 patients, and L3-L4 in three patients. All patients underwent reoperation using the TLIF technique. Outcomes were evaluated using the Oswestry disability index (ODI), visual analogue scale (VAS) scores for low back pain and leg pain, and the Japanese Orthopaedic Association (JOA) score, based on the results of physical examinations and questionnaires. The range of motion and disc height index of the operative segment were compared between preoperative and postoperative radiographs. The mean follow-up period was 4.1 years. The VAS scores for low back pain and leg pain, ODI, and JOA score improved significantly between the preoperative and final follow-up evaluations. The mean recovery rate of the JOA score was 89.0%. The disc space height and stability at the fused level were significantly improved after surgery. The fusion rate at the final follow-up was 93.2%. There were no major complications. These results indicate that TLIF can be considered an effective, reliable, and safe alternative procedure for the treatment of rLDH.

Abstract
Far lateral lumbar intervertebral disk herniation (FLLIDH) most commonly occurs far lateral to the intervertebral facet at L3-L4 and L4-L5 and accounts for 3.8% of all lumbar disk herniations. Traditional surgery for FLLIDH involves massive surgical trauma, damage to the spinal structure, and instability of the lumbar spine. The goals of this study were to perform a systematic review of the literature and investigate the clinical outcomes of transforaminal percutaneous endoscopic surgery in the treatment of FLLIDH. Between October 2010 and May 2012, fifteen patients diagnosed with FLLIDH underwent transforaminal percutaneous endoscopic surgery at the authors' institution to remove the herniated disk and release the nerve root. Pain was measured pre- and postoperatively with a visual analog pain scale (VAS), and postoperative outcomes were evaluated using MacNab's criteria. A PubMed database search was conducted for the systematic review. Median operative time was 100 minutes (range, 80-140 minutes). Median volume of intraoperative blood loss was 20 mL (range, 10-50 mL). Patients were followed postoperatively for a median of 6 months (range, 1-12 months). MacNab's criteria rated 12 (80.0%) surgical outcomes as excellent, 2 (13.3%) as good, and 1 (6.7%) as fair. The systematic review included 14 studies. Transforaminal percutaneous endoscopic surgery appears to be a safe and effective minimally invasive procedure for treating FLLIDH. However, as demand for this type of surgery increases, the possibility of intraoperative aggravated leg pain and compression injury of the ganglion must be considered.

Abstract
PURPOSE Percutaneous endoscopic interlaminar discectomy (PEID) is a widely used minimally invasive procedure which shows satisfying outcomes in the adult population. However, pediatric lumbar disc herniations (PLDH) occur in growing spines and are less related to degeneration, which makes them different from the adult disc herniations. This study evaluates the clinical outcomes of PEID in treating PLDH. METHODS A prospect study was done in the period from June 2010 to December 2012, which included 29 consecutive pediatric patients with a mean age of 16.4 years (range, 13 to 18 years) who underwent PEID for single level lumbar disc herniation. The following measuring tools were used: visual analog scale (VAS) for back and leg pain, Oswestry Disability Index (ODI), and Macnab criteria. RESULTS There were no severe complications such as dural tear or nerve root damage found in our study. The mean follow-up period was 19.7 months. The VAS score for leg and back pain decreased dramatically at 1 day postoperatively and kept decreasing until the follow-up visit at 3 months postoperatively, when it became stable at a low level. ODI kept improving until the follow-up visit at 6 months postoperatively when it reached a stable low level. Of the patients, 91% reported no longer having leg pain and 9% had occasional leg pain at last follow-up. CONCLUSIONS PEID shows a satisfying outcome with a minimal rate of complications. It has the advantages of minimal traumatization and scar formation and is a safe and effective treatment for PLDH.

Abstract
In appropriate situations, extensive decompression with laminectomy often continues to be described as the method of choice for operations involving lumbar zygoapophyseal joint (z-joint) cysts. Tissue-sparing procedures are nevertheless becoming more common. Endoscopic techniques have become the standard procedures in many areas because of the advantages they offer in terms of surgical technique and in rehabilitation. One key aspect in spinal surgery was the development of instruments for sufficient bone resection carried out under continuous visual control. This enabled endoscopes to be used when operating on z-joint cysts. The objective of this prospective study was to examine the technical possibilities for the full-endoscopic interlaminar and transforaminal technique in lumbar z-joint cysts. A total of 74 patients were followed up for 2 years. The results show that 85% of the patients no longer have any leg pain or that the pain had been almost completely eliminated, and 11 % experience occasional pain. The complication rate was low. The full-endoscopic techniques brought advantages in the following areas: operation, complications, traumatization, and rehabilitation. The recorded results show that full-endoscopic resection of a z-joint cyst using an interlaminar and transforaminal approach provides an adequate and safe supplement, and is an alternative to conventional procedures when the indication criteria are fulfilled. It also offers the advantages of a minimally invasive intervention.

Abstract
PURPOSE Assessing the benefits of surgical treatments for sciatica is critical for clinical and policy decision-making. To compare minimally invasive (MI) and conventional microdiscectomy (MD) for patients with sciatica due to lumbar disc herniation. METHODS A systematic review and meta-analysis of controlled clinical trials including patients with sciatica due to lumbar disc herniation. Conventional microdiscectomy was compared separately with: (1) Interlaminar MI discectomy (ILMI vs. MD); (2) Transforaminal MI discectomy (TFMI vs. MD). OUTCOMES Back pain, leg pain, function, improvement, work status, operative time, blood loss, length of hospital stay, complications, reoperations, analgesics and cost outcomes were extracted and risk of bias assessed. Pooled effect estimates were calculated using random effect meta-analysis. RESULTS Twenty-nine studies, 16 RCTs and 13 non-randomised studies (n = 4,472), were included. Clinical outcomes were not different between the surgery types. There is low quality evidence that ILMI takes 11 min longer, results in 52 ml less blood loss and reduces mean length of hospital stay by 1.5 days. There were no differences in complications or reoperations. The main limitations were high risk of bias, low number of studies and small sample sizes comparing TF with MD. CONCLUSIONS There is moderate to low quality evidence of no differences in clinical outcomes between MI surgery and conventional microdiscectomy for patients with sciatica due to lumbar disc herniation. Studies comparing transforaminal MI with conventional surgery with sufficient sample size and methodological robustness are lacking.

Abstract
STUDY DESIGN Systematic review. OBJECTIVE To search and analyse randomised controlled trials (RCTs) published since the Cochrane review by Gibson and Waddell (2007) comparing microendoscopic discectomy (MED) with open discectomy (OD) or microdiscectomy (MD) and to assess whether MED improves patient-reported outcomes. Discectomy for symptomatic herniated lumbar discs is an effective operative treatment. A number of operative techniques exist including OD, MD, and MED. A 2007 Cochrane review identified OD as an effective treatment for symptom improvement, and found sufficient evidence for MD. However, evidence for MED was lacking. METHODS A systematic review of Medline and Embase was carried out. Aiming to identify RCTs carried out after 2007, which compared OD with MD and MED which reported the Oswestry disability index (ODI) as an outcome. RESULTS Four RCTs were identified. None of the studies found a significant difference in the ODI scores between study groups at any time point. Three studies compared MED to OD and one compared OD, MD, and MED. The largest study reported an increased number of severe complications in the MED group. CONCLUSIONS There is some evidence to suggest that MED performed by surgeons skilled in the technique in tertiary referral centres is as effective as OD.

Abstract
We report our early clinical experience with percutaneous endoscopic lumbar discectomy (PELD) for herniated nucleus pulposus (HNP) in the lumbar spine. We introduced PELD to our clinical practice in June 2009. A total of 311 patients with degenerative lumbar spine disease were treated in our hospital up to August 2011. Thirty-seven patients with lumbar HNP were treated by PELD. PELD was carried out under local anesthesia, and the endoscope was continuously irrigated with saline. Twenty-eight patients were treated through the transforaminal approach, 5 were treated through the interlaminar approach, and 4 were treated through the extraforaminal approach. Surgery was discontinued due to uncontrollable intraoperative pain or anatomical inaccessibility in one case of the interlaminar approach and 2 cases of the extraforaminal approach. In the other 34 patients, the elapsed time of surgery was 34 to 103 minutes (mean 62.4 minutes). Extracorporeal blood loss was insignificant. Immediate symptom relief was achieved in all patients, and postoperative magnetic resonance imaging revealed sufficient removal of the HNP. The length of the postoperative hospital stay was 1 or 2 days in all patients. The surgical method of PELD is completely different from percutaneous nucleotomy, and the aim is to directly remove the HNP with minimum damage to the musculoskeletal structure. Although this study is based on our early clinical outcomes, PELD seemed to be a promising minimally invasive surgery for HNP in the lumbar spine.
