Endoscopic Lumbar Discectomy ◽

Time Point

Abstract Background: Obese patients are at risk of complications such as poor wound healing and increased infection rates after spinal surgery. Percutaneous endoscopic lumbar discectomy (PELD) has advantages over conventional open surgery in the treatment of obese adult patients with lumbar disc herniation (LDH) because it can decrease perioperative complications and enhance satisfaction degrees of patients. However, no clinical studies have evaluated the efficacy of PELD in obese adolescents with LDH. This study aimed to evaluate the efficacy of PELD in the treatment of obese ALDH.Methods: We retrospectively collected clinical data from 208 patients with single-segment ALDH who underwent PELD treatment in our hospital between January 2015 and December 2019. According to the body mass index classification standard of obesity for adolescents in our country, the patients were divided into obese and non-obese groups (control group). Based on the preoperative baseline data of the two groups, propensity score matching was performed to select patients from the two groups for the comparative study. Perioperative data included operative time, intraoperative blood loss and length of postoperative hospitalization. The visual analog scale (VAS), Oswestry disability index (ODI) and modified MacNab criteria were recorded as the main indicators of the surgical outcome, and the recurrence rate and incidence of complications were recorded as the minor indicators. Results: The obese and control groups included 45 patients each after 1:1 propensity score matching. Both groups showed improvements in VAS and ODI scores after surgery and at each follow-up time point (p < 0.05). However, there was no significant statistical difference in VAS and ODI scores between the two groups at each follow-up time point (p >0.05). In addition, the differences in operative time, intraoperative blood loss, length of postoperative hospitalization, incidence of complications, and recurrence rate were not statistically significant between the two groups (p >0.05). At the final follow-up, there was no significant difference in the excellent and good rate of MacNab classification between the two groups (p >0.05). Conclusion: PELD is a safe and effective minimally invasive technique for the treatment of obese patients with ALDH. The efficacy of PELD in obese and non-obese patients with ALDH was comparable.

Abstract Background Obese patients are at risk of complications after spinal surgery. Full-endoscopic lumbar discectomy (FELD) has advantages over conventional open surgery in the treatment of obese adult patients with lumbar disc herniation (LDH) because it can decrease perioperative complications and enhance the degree of patient satisfaction. However, no clinical studies have evaluated the efficacy of FELD in obese adolescents with LDH (ALDH). This study aimed to evaluate the efficacy of FELD for the treatment of obese ALDH. Methods We retrospectively collected clinical data from 208 patients with single-segment ALDH who underwent FELD in our hospital between January 2015 and December 2019. According to the WHO classification of obesity, the patients were divided into obese (BMI ≥30 kg/m2) and non-obese (BMI < 30 kg/m2) groups (control group). Based on the preoperative baseline data of the two groups, propensity score matching was performed to select patients from these groups for a comparative study. Perioperative data included operative time, intraoperative blood loss, and length of postoperative hospitalization. The visual analog scale (VAS), Oswestry disability index (ODI), and modified MacNab criteria were recorded as the main indicators of the surgical outcome. Recurrence rate and incidence of complications were recorded as minor indicators. Results Twenty-eight patients and 80 patients were included in the obese and non-obese groups, respectively, after 1:4 propensity score matching. Both groups showed improvements in VAS and ODI scores after surgery and at each follow-up time point (p < 0.05). However, there was no significant statistical difference in the surgical outcomes between the two groups at each follow-up time point (p > 0.05). The differences in operative time, intraoperative blood loss, and length of postoperative hospitalization were not statistically significant between the two groups (p > 0.05). Conclusion FELD is a safe and effective minimally invasive technique for treating obese patients with ALDH. The efficacy of FELD in obese and non-obese patients with ALDH was comparable.

Abstract Background Percutaneous endoscopic lumbar discectomy (PELD) is satisfactory for hospitalized patients with lumbar disc herniation (LDH). Currently, only a few studies have reported about the day surgery patients undergoing PELD. Methods A total of 267 patients with LDH underwent PELD during day surgery and were followed up for at least 3 years. Clinical outcomes were assessed using the visual analog scale (VAS) for leg and lower back pain (VAS-B and VAS-L, respectively) and the Oswestry disability index (ODI). The radiological outcomes, such as lumbar lordosis (LL), sacral slope (SS), the disc-height ratio, and disc instability, were recorded and compared. The clinical effects between patients treated by PELD during day surgery and microendoscopic discectomy (MED) for contemporaneous hospitalized 116 patients with LDH were compared. Results Patients treated by PELD had lower blood loss and shorter hospital stay (P < 0.001) compared to those treated by MED. VAS-L, VAS-B, and ODI decreased significantly after PELD than before the operation and 3 years postoperatively. The postoperative VAS-B in the PELD group was significantly decreased than in the MED group (P = 0.001). The complications rate was 9.4% in the PELD group and 12.1% in the MED group (P = 0.471). The 1-year postoperative recurrence rate in the PELD group was much higher than that in MED group (P = 0.042). The postoperative LL and SS in the PELD group improved significantly compared to the values in the MED group (P < 0.001). According to the disc-height ratio at 3-year follow-up, a significant height loss was observed in the MED group than in the PELD group (P = 0.014). Conclusions Although the 1-year postoperative recurrence rate was relatively high, the day surgery for LDH undergoing PELD had advantages in terms of less blood loss intraoperatively, short hospital stay, efficacy for back pain, and efficiency to maintain lumbar physiological curvature.

Background. Among the surgical methods for lumbar disc herniation, open lumbar microdiscectomy is considered the gold standard. Recently, percutaneous endoscopic lumbar discectomy is also commonly performed for lumbar disc herniation for its various strong points. Objectives. The present study aims to examine whether percutaneous endoscopic lumbar discectomy and open lumbar microdiscectomy show better results as surgical treatments for lumbar disc herniation in the Korean population. Methods. In the present meta-analysis, papers on Korean patients who underwent open lumbar microdiscectomy and percutaneous endoscopic lumbar discectomy were searched, both of which are surgical methods to treat lumbar disc herniation. The papers from 1973, when percutaneous endoscopic lumbar discectomy was first introduced, to March 2018 were searched at the databases of MEDLINE, EMBASE, PubMed, and Cochrane Library. Results. Seven papers with 1254 patients were selected. A comparison study revealed that percutaneous endoscopic lumbar discectomy had significantly better results than open lumbar microdiscectomy in the visual analogue pain scale at the final follow-up (leg: mean difference [MD]=-0.35; 95% confidence interval [CI]=-0.61, -0.09; p=0.009; back: MD=-0.79; 95% confidence interval [CI]=-1.42, -0.17; p=0.01), Oswestry Disability Index (MD=-2.12; 95% CI=-4.25, 0.01; p=0.05), operation time (MD=-23.06; 95% CI=-32.42, -13.70; p<0.00001), and hospital stay (MD=-4.64; 95% CI=-6.37, -2.90; p<0.00001). There were no statistical differences in the MacNab classification (odds ratio [OR]=1.02; 95% CI=0.71, 1.49; p=0.90), complication rate (OR=0.72; 95% CI=0.20, 2.62; p=0.62), recurrence rate (OR=0.83; 95% CI=0.50, 1.38; p=0.47), and reoperation rate (OR=1.45; 95% CI=0.89, 2.35; p=0.13). Limitations. All 7 papers used for the meta-analysis were non-RCTs. Some differences (type of surgery (primary or revisional), treatment options before the operation, follow-up period, etc.) existed depending on the selected paper, and the sample size was small as well. Conclusion. While percutaneous endoscopic lumbar discectomy showed better results than open lumbar microdiscectomy in some items, open lumbar microdiscectomy still showed good clinical results, and it is therefore reckoned that a randomized controlled trial with a large sample size would be required in the future to compare these two surgical methods.

Abstract Purpose To compare the efficacy of conventional interlaminar fenestration discectomy (IFD) with transforaminal endoscopic lumbar discectomy (TELD) for treating lumbar disc herniation (LDH). Methods The clinical data of 1100 patients who had been diagnosed with LDH between January 2012 and December 2017 were retrospectively analysed. IFD was performed on 605 patients in Group A, whereas TELD was performed on 505 patients in Group B. The Oswestry Disability Index, Visual Analogue Scale for pain and modified MacNab criteria were used to evaluate the outcomes. The surgery duration, intraoperative blood loss, postoperative off-bed activity and postoperative length of hospital stay were recorded. Results The follow-up period ranged from 24 to 60 months, with an average of 43 months. The excellent and good outcome rates were 93.5% in Group A and 92.6% in Group B. There was no significant difference in efficacy between the groups (P > 0.05). However, Group B had significantly less intraoperative blood loss and shorter bed rest duration and postoperative length of hospital stay than Group A (P < 0.05). There were two cases of postoperative recurrence in Group A and three in Group B. Conclusions Although conventional IFD and TELD had similar levels of efficacy in treating LDH, TELD had several advantages. There was less intraoperative bleeding, shorter length of hospital stay and shorter bed rest duration. It can be considered a safe and effective surgical option for treating LDH.

Abstract Background In recent decades, endoscopic techniques to treat lumbar disc herniation (LDH) have gained popularity in clinical practice. However, there is little literature on the use of percutaneous endoscopic lumbar discectomy (PELD) to treat cauda equina syndrome (CES) due to LDH. This study aims to evaluate the feasibility and clinical efficacy of PELD for treating CES caused by disc herniation, and as well as to report some technical strategies. Methods Between October 2012 and April 2018, 15 patients with CES caused by LDH at the early and intermediate stages of Shi’s classification were selected as the subjects of study, and underwent PELD. All patients were followed up for at least two years. The patients’ back pain and leg pain were evaluated using visual analogue scale (VAS) scores and the Oswestry Disability Index (ODI). Patient satisfaction was evaluated using the MacNab outcome scale. Clinical outcomes were measured preoperatively and at 3 days, 3 months, 6 months and the last follow-up. Results The VAS score for back pain, leg pain and ODI score significantly decreased from preoperatively scores of 6.67 ± 1.05, 7.13 ± 1.19 and 62.0 ± 6.85 respectively, to postoperatively cores of 1.80 ± 0.41, 1.47 ± 0.52 and 12.93 ± 1.03 at the last follow-up postoperatively. These postoperative scores were all significantly different compared with preoperative scores (P < 0.01). According to the modified MacNab outcome scale, 86.67% of these patients had excellent and good outcomes at the final follow-up. Complications included one patient with cerebrospinal fluid leakage and one patient who developed recurrent herniation; the latter patient finally achieved satisfactory results after reoperation. Conclusion PELD could be used as an alternative surgical method for the treatment of CES due to LDH in properly selected cases and appropriate patient selection. However, the operator should pay attention to foraminoplasty to enlarge the working space.

Background: Herniated lumbar disc is a common cause of lumbosacral pain. Endoscopic interlaminar lumbar discectomy (ILD) is a well-established technique that provided comparable results to micro-discectomy. The aim of the study is to describe the learning curve of endoscopic ILD and explore measures that could improve effectiveness and decrease blood loss and operative time with accumulation of reasonable experience. Methods: This retrospective cohort study included 65 patients presenting with symptomatic herniated lumbar disc who underwent endoscopic ILD. Patients were divided into two groups: Group I (standard technique) and Group II (modified technique). Collected data included patients’ age, gender, preoperative manifestations, visual analog score (VAS) for pain, Oswestry Disability Index (ODI), disc level, operative time, intraoperative blood loss, complications, and follow-up data at 1, 6, and 12 months postoperatively. Primary outcomes included total operative time, amount of intraoperative blood loss, and post-operative improvement in pain. Secondary outcomes included intraoperative complications, rate of conversion to open surgery, and recurrence. Results: Post-operative VAS and ODI improved significantly in both groups. Mean total surgical time and intraoperative blood loss were significantly lower in Group II compared to Group I (P < 0.001). The learning curves for operative time and intraoperative blood loss were shallow in Group I, and almost flattened in Group II. Complications were recorded in only three cases, and no symptomatic recurrences were reported. Conclusion: The learning curve of endoscopic ILD was shallow with standard technique, indicating difficulties in mastering the procedure. The proposed modified technique helped reaching the required level of proficiency in the early phase of the curve, providing a significant reduction in operative time and blood loss, with comparable effectiveness and safety as the standard technique.

Abstract Background: Although numerous studies have shown good clinical results of percutaneous endoscopic lumbar discectomy (PELD) for hospitalized patients with lumbar disc herniation (LDH), there are few articles that report on the day surgery patients undergoing PELD.Methods: Atotal of 267 patients with LDH received PELD during day surgery were followed up for at least 3 years. Relevant data and clinical outcomeswere recorded and assessed. Meanwhile, we compared the clinical effects between patients treated by PELD during day surgery and microendoscopic discectomy (MED) for contemporaneous hospitalized patients with LDH (116 patients).Results: Patients treated by PELD had lower blood loss (10.8 ± 4.1 mL, 71.3 ± 23.3 mL,respectively; P < 0.001) and shorter hospital stay ( 22.7 ± 4.2 hours, 48.1 ± 22.6 hours, respectively; P < 0.001 ) compared with patients treated by MED. The visual analogue scale (VAS) for leg and back pain (VAS-L and VAS-B, respectively) and Oswestry disability index (ODI) decreased significantly after PELD than those before the operation at 3 years postoperative, and the postoperative VAS-B in PELD group was significantly decreased from the MED group ( P = 0.001). The complications rate was 9.4% (25/267) in the PELD group and 12.1% (14/116) in the MED group, without significant difference ( P = 0.471). The 1-year postoperative recurrence rate in PELD group ( 5.2%, 14/267) was much higher than that in MED group ( 0.9%, 1/116) ( P = 0.042). The postoperative lumbar lordosis（LL）(34.0 ±10.3 ), and sacral slope（SS) (27.5 ± 5.6) in PELD group improved significantly compared with the values in MED group (26.9 ± 9.8, 23.6 ± 6.8, respectively; all P < 0.001). The disc-height ratio at 3-year follow-up was ( 85.7 ± 6.4) % of the preoperative disc height in PELD group while ( 81.9 ± 7.0) % in MED group，with significant height loss in MED group ( P = 0.014).Conclusions: Day surgery for LDH undergoing PELD has favorable long-term outcomes.

Background: Percutaneous endoscopic lumbar discectomy (PELD) can only relieve mechanical compression but cannot directly reduce the inflammatory reaction of the adjacent nerve root, which contributes to persistent pain and physical disabilities postoperatively. Numerous studies have explored the application of epidural steroids after an open lumbar discectomy in relieving pain by reducing local inflammatory reactions and further peridural scar formation. Objectives: To explore that whether “cocktail treatment” in which a gelatin sponge was impregnated with ropivacaine, dexamethasone, and vitamin B12 promoted early postoperative recovery after PELD. Study Design: Retrospective, case-controlled study. Setting: All data were from Hong-Hui Hospital in Xi’an. Methods: Between January 2016 and January 2017, 100 patients of single-level lumbar disc herniation were treated with PELD in our hospitals. The cocktail treatment was applied in the first 50 patients (group cocktail), and an equal size gelatin sponge without drugs was used in the other 50 patients as control (group noncocktail). The clinical outcome evaluation included the Visual Analog Scale (VAS) score for back and leg pain and Oswestry Disability Index (ODI) score. Results: There was a significant difference in the mean periods of return to work (4.25 ± 1.88 weeks in the cocktail group and 5.18 ± 2.19 weeks in the noncocktail group) (P < 0.01). Compared with the preoperative data, a significant improvement in VAS scores of back pain and sciatica and ODI were observed in each follow-up interval (P < 0.05, respectively). In the noncocktail group, there were visible fluctuations in the 3 indicators within the first week after surgery. This phenomenon was not observed in the cocktail group, a difference that was statistically significant (P < 0.05, respectively). In further follow-up, no significant differences were observed between the 2 groups (P > 0.05, respectively). Limitations: The nonrandomized, single-center, retrospective design is a major limitation of this study. Conclusions: The “cocktail treatment” with a gelatin sponge impregnated with ropivacaine, dexamethasone, and vitamin B12 promotes early and satisfactory back and leg pain relief and fast functional recovery after PELD.

Abstract Background: Symptomatic lumbar disc herniation is rarely seen among adolescents. Adolescent lumbar disc herniation (ALDH) accounts for 0.5% to 6.8% of all those treated. Evidently, to our knowledge, no studies have emphasized the operative technique to treat two contiguous level adolescent lumbar disc herniation simultaneously. In this study, we aim to investigate the feasibility and advantages of one-stage full-endoscopic lumbar discectomy（FELD）for two contiguous level ALDH. This is the first paper, to my knowledge, dealing with two contiguous level ALDH simultaneously with one-stage full-endoscopic lumbar discectomy.Methods: Between January 2014 and December 2019, patients received FELD surgery for lumbar disc herniation (LDH) in 2 main minimally invasive spine center of China were selected for screening of this study. Data of 5877 cases were retrospectively analyzed (2780 cases and 3097 cases, respectively). The inclusion criteria were patient under 21-year old, two contiguous level symptomatic lumbar disc herniation received one-stage 2 level PELD surgery. Visual analog scale (VAS) scores and modified Macnab criteria were used to assess the preoperative and postoperative clinical results.Results: 11 patients were enrolled in this study (0.19%,11/5877), 8 patients were male and 3 were female. 9 patients with LDH in the same side underwent single-incision 2 level FELD surgery via transforaminal approach. 2 patients with LDH in different side underwent FELD surgery via combined transforaminal and interlaminar approach. There were no immediate perioperative complications. The visual analog scale (VAS) decreased significantly in both early and late follow-up evaluations and these score demonstrated significant improvement in late follow-up (P <0.01). For the modified MacNab criteria, the final outcome results were excellent in 9 patients (81.8%), good in 1 patients (0.9%), fair in1 patients (0.9%), and the overall success rate was 90.9%.Conclusion: One-stage full-endoscopic lumbar discectomy for 2 level symptomatic ALDH is an effective and less invasive method, which can be considered as an alternative good technique for selected adolescent patients.
