OBJECTIVELumbar disc herniation (LDH) in the pediatric population is rare and exhibits unique characteristics compared with adult LDH. There are limited data regarding the safety and efficacy of minimally invasive surgery (MIS) using tubular retractors in pediatric patients with LDH. Here, the outcomes of MIS tubular microdiscectomy for the treatment of pediatric LDH are evaluated.METHODSTwelve consecutive pediatric patients with LDH were treated with MIS tubular microdiscectomy at the authors’ institution between July 2011 and October 2015. Data were gathered from retrospective chart review and from mail or electronic questionnaires. The Macnab criteria and the Oswestry Disability Index (ODI) were used for outcome measurements.RESULTSThe mean age at surgery was 17 ± 1.6 years (range 13–19 years). Seven patients were female (58%). Prior to surgical intervention, 100% of patients underwent conservative treatment, and 50% had epidural steroid injections. Preoperative low-back and leg pain, positive straight leg raise, and myotomal leg weakness were noted in 100%, 83%, and 67% of patients, respectively. The median duration of symptoms prior to surgery was 9 months (range 1–36 months). The LDH level was L5–S1 in 75% of patients and L4–5 in 25%. The mean ± SD operative time was 90 ± 21 minutes, the estimated blood loss was ≤ 25 ml in 92% of patients (maximum 50 ml), and no intraoperative or postoperative complications were noted at 30 days. The median hospital length of stay was 1 day (range 0–3 days). The median follow-up duration was 2.2 years (range 0–5.8 years). One patient experienced reherniation at 18 months after the initial operation and required a second same-level MIS tubular microdiscectomy to achieve resolution of symptoms. Of the 11 patients seen for follow-up, 10 patients (91%) reported excellent or good satisfaction according to the Macnab criteria at the last follow-up. Only 1 patient reported a fair level of satisfaction by using the same criteria. Seven patients completed an ODI evaluation at the last follow-up. For these 7 patients, the mean ODI low-back pain score was 19.7% (SEM 2.8%).CONCLUSIONSTo the authors’ knowledge, this is the longest outcomes study and the largest series of pediatric patients with LDH who were treated with MIS microdiscectomy using tubular retractors. These data suggest that MIS tubular microdiscectomy is safe and efficacious for pediatric LDH. Larger prospective cohort studies with longer follow-up are needed to better evaluate the long-term efficacy of MIS tubular microdiscectomy versus other open and MIS techniques for the treatment of pediatric LDH.

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 Objective: In Brazil, there are no studies comparing endoscopic treatment of lumbar disc herniation with the conventional open technique in SUS (Unified Health System) with regard to hospitalization time and complications occurring within one year, which is the objective of this study. Methods: A survey of 32 surgeries performed in 2019 (11 open and 21 endoscopic) to evaluate pain parameters before and after surgery (VAS), days of hospitalization, and complications. The data were submitted to statistical analysis (ANOVA) using the Kruskal-Wallis test. Results: Fourteen patients were female and eighteen were male, with a mean age of 41.35 years (p> 0.05 between sexes). The pre- and postoperative VAS for pain radiating to the lower limb were similar between the groups: 8.5 ± 0.82 with the open technique and 8.19 ± 1.15 with endoscopic technique. In both groups there was an improvement in the pain pattern with a significant reduction in the VAS (p < 0.05) and there was no statistical relevance between the groups in terms of pain improvement. There was statistical relevance between the groups in the comparison of days of hospitalization required, with the group submitted to endoscopic surgery having a lower number of days. The complications reported were compatible with those found in the literature (postoperative dysesthesia, new herniation). Conclusions: The endoscopic technique resulted in an important reduction in the number of days of hospitalization, a factor with a high impact on the costs of any surgical procedure, which can be a determining factor in the feasibility of minimally invasive techniques. Level of evidence IV; Therapeutic Study.

Abstract Background: Trans-sacral epiduroscopic laser decompression (SELD) using slender epiduroscope and a holmium YAG laser is one of the minimally invasive surgical options for lumbar disc herniation. However, the learning curve of SELD and the effect of surgical proficiency on clinical outcome have not yet been established. We investigated patients with lumbar disc herniation undergoing SELD to report the clinical outcome and learning curve. Methods: Retrospective analysis of clinical outcome and learning curve were performed at a single center from clinical data collected from November 2015 to November 2018. A total of 82 patients who underwent single-level SELD for lumbar disc herniation with a minimum follow-up of 6.0 months were enrolled. Based on the findings that the cut-off of familiarity was 20 cases according to the cumulative study of operation time, patients were allocated to two groups: early group (n = 20) and late group (n = 62). The surgical, clinical, and radiological outcomes were retrospectively evaluated between the two groups to analyze the learning curve of SELD.Results: According to linear and log regression analyses, the operation time was obtained by the formula: operation time = 58.825 - (0.181 × [case number]) (p < 0.001). The mean operation time was significantly different between the two groups (mean 56.95 minutes; 95% confidence interval [CI], 49.12–64.78 in the early group versus mean 45.34 minutes; 95% CI, 42.45–48.22 in the late group; p = 0.008, non-parametric Mann-Whitney U test).Baseline characteristics, including demographic data, clinical factors, and findings of preoperative magnetic resonance imaging, did not differ between the two groups. Also, there was no significant difference in terms of surgical outcomes, including complication and failure rates, as well as clinical and radiological outcomes between the two groups.Conclusion: The learning curve of SELD was not as steep as that of other minimally invasive spinal surgery techniques, and the experience of surgery was not an influencing factor for outcome variation.
