Recurrent Lumbar Disc Herniation

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 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.

Introduction: Lumbar disc herniation (LDH) is one of the most common causes for low back pain and related disabilities. Surgery is indicated in patients who do not respond to the conservative measures for at least 6 weeks or symptoms are worsened. Microendoscopic discectomy (MED) is a well-accepted minimally invasive surgical technique with similar results compared to open surgery. The purpose of this study was to evaluate the clinical outcome, functional improvement and analyze complications during MED. Methods: A retrospective analysis was conducted in 156 patients who were operated for single or double level LDH using MED between 2016 and 2018. All patients were evaluated for pain and disability using visual analogue scale (VAS) and Oswestry disability index (ODI), respectively. Modified MabNab’s criteria used to evaluate overall outcome of surgery. Operation time, estimated blood loss (EBL), hospital stay and time to return back to previous activities were evaluated. Complications and revisions were noted during follow-up to analyze clinical results. Paired t-test was used to evaluate statistical difference in VAS and ODI score during follow-up. Results: All patients were followed up at 6 weeks, 3 months, 6 months, 1 year and yearly thereafter postoperatively. Average follow-up was 25.5±9.7 months and average age was 45.0±12.7 years. Average VAS scores improved significantly from preoperative 8.7±0.8 to 2.0±1.1 postoperatively (p<0.0001). Average preoperative ODI improved significantly from 53.8±6.1 to 22.6±5.1 postoperatively (p<0.0001). Both score were maintained at the final follow-up. The average time to return to previous activity level was 35.7±14.3 days. Average operation time, EBL and hospital stay were 57.6±14.6 minutes, 36.7±13.1 mL and 2.4±0.7 days, respectively. There were total 19 (12.2%) complications and 12 (7.7%) revisions in the series. Overall clinical outcome was excellent, good, fair and poor in 73.1%, 20.5%, 5.1% and 1.3% of cases using modi

Background: Most lumbar disc herniations can be successfully treated conservatively. However, massive lumbar disc herniations are often treated surgically to avoid permanent cauda equina syndromes/neurological deficits and potential litigation. Nevertheless, here, we present a 51-year-old female who refused lumbar surgery due to coronavirus disease 2019 (COVID-19) and sustained a full spontaneous recovery without surgical intervention. Case Description: A 51-year-old female presented with a massive lumbar disc herniation at the L5S1 level. Despite refusing surgery for fear of getting COVID-19, she spontaneously neurologically improved without any residual neurological or radiographic sequelae. Conclusion: Although the vast majority of patients with massive lumbar disc herniations are managed surgically, there are rare instances in which nonoperative management may be successful.
