          Abstract

          Abstract Introduction Low back pain is a clinical condition with a multifactorial etiopathogenesis, which has a high socioeconomic impact, especially in the economically active population, as it is associated with frequent absenteeism and reduced quality of life. Through intervertebral disc degeneration, a progressive instability of the compromised region is observed, triggering a harmful positive feedback mechanism that further promotes intervertebral disc disease. Built by the interaction between the predisposing biopsychosocial components, a multidisciplinary therapeutic proposition is suggested. In persistent low back pain, treatment involves surgical procedures such as Percutaneous Lumbar Discectomy. Objectives to evaluate the scientific evidence regarding the clinical outcomes and safety of this surgery. Method systematic review duly registered in Prospero (CRD42022370811), based on the PICOD question, elaborated from a Boolean search in different databases for scientific articles, evaluated and selected in a paired way based on the eligibility criteria. In addition to extracting data related to the proposed objectives, the articles included were evaluated in relation to their level of evidence and strength of recommendation. Results among the 12 articles included, it was observed that it is a clinically effective and safe procedure. In the set of evidences gathered, they are of high and moderate level of evidence with respective strength of recommendation strong/good and weak/moderate. Conclusion Percutaneous Lumbar Discectomy promotes significant reduction of pain and increase in body functionality, in addition to preserving local musculoskeletal structures and preventing post-surgical joint instability. It is, therefore, a safe and clinically effective minimally invasive procedure for patients with herniated discs.

          Resumo Introdução a lombalgia é uma condição clínica de etiopatogenia multifatorial, que desencadeia um elevado impacto socioeconômico especialmente na população economicamente ativa, por associar-se ao absenteísmo frequente e à redução da qualidade de vida. Observa-se mediante a degeneração do disco intervertebral, uma instabilidade progressiva da região comprometida desencadeando um mecanismo de feedback positivo prejudicial que promove ainda mais a doença do disco intervertebral. Edificada pela interação entre os componentes biopsicossocial predisponentes, sugere-se uma proposição terapêutica multidisciplinar. Na dor lombar persistente o tratamento envolve procedimentos cirúrgicos como a Discectomia Percutânea Lombar. Objetivo avaliar as evidencias científicas relativas aos desfechos clínicos e à segurança desta cirurgia. Método revisão sistemática devidamente registrada no Prospero (CRD42022370811), fundamentada na pergunta PICOD acrônimo para Paciente, Intervenção, Comparação, Desfechos (outcomes) e Design, elaborada a partir de busca booleana em diferentes bases de dados por artigos científicos, avaliados e selecionados de forma pareado com base nos critérios de elegibilidade. Além da extração de dados relativos aos objetivos propostos, os artigos incluídos foram avaliados em relação ao respectivo nível de evidencia e força de recomendação. Resultados dentre os 12 artigos incluídos, observou-se que se trata de um procedimento clinicamente efetivo e seguro. No conjunto de evidencias reunidas são de alto e moderado nível de evidencia com respectiva força de recomendação forte/boa e, fraca/moderada. Conclusão a Discectomia Percutânea Lombar promove relevante redução da dor e aumento da funcionalidade corporal, além de preservar as estruturas musculoesqueléticas locais e prevenir a instabilidade articular pós-cirúrgica. Trata-se, portanto, de um procedimento minimamente invasivo seguro e clinicamente efetivo para os pacientes portadores de hérnia discal.

          Low back pain

          Low back pain covers a spectrum of different types of pain (eg, nociceptive, neuropathic and nociplastic, or non-specific) that frequently overlap. The elements comprising the lumbar spine (eg, soft tissue, vertebrae, zygapophyseal and sacroiliac joints, intervertebral discs, and neurovascular structures) are prone to different stressors, and each of these, alone or in combination, can contribute to low back pain. Due to numerous factors related to low back pain, and the low specificity of imaging and diagnostic injections, diagnostic methods for this condition continue to be a subject of controversy. The biopsychosocial model posits low back pain to be a dynamic interaction between social, psychological, and biological factors that can both predispose to and result from injury, and should be considered when devising interdisciplinary treatment plans. Prevention of low back pain is recognised as a pivotal challenge in high-risk populations to help tackle high health-care costs related to therapy and rehabilitation. To a large extent, therapy depends on pain classification, and usually starts with self-care and pharmacotherapy in combination with non-pharmacological methods, such as physical therapies and psychological treatments in appropriate patients. For refractory low back pain, a wide range of non-surgical (eg, epidural steroid injections and spinal cord stimulation for neuropathic pain, and radiofrequency ablation and intra-articular steroid injections for mechanical pain) and surgical (eg, decompression for neuropathic pain, disc replacement, and fusion for mechanical causes) treatment options are available in carefully selected patients. Most treatment options address only single, solitary causes and given the complex nature of low back pain, a multimodal interdisciplinary approach is necessary. Although globally recognised as an important health and socioeconomic challenge with an expected increase in prevalence, low back pain continues to have tremendous potential for improvement in both diagnostic and therapeutic aspects. Future research on low back pain should focus on improving the accuracy and objectivity of diagnostic assessments, and devising treatment algorithms that consider unique biological, psychological, and social factors. High-quality comparative-effectiveness and randomised controlled trials with longer follow-up periods that aim to establish the efficacy and cost-effectiveness of low back pain management are warranted.

            The economic burden of back pain in the UK.

            This paper reports the results of a 'cost-of-illness' study of the socio-economic costs of back pain in the UK. It estimates the direct health care cost of back pain in 1998 to be pound1632 million. Approximately 35% of this cost relates to services provided in the private sector and thus is most likely paid for directly by patients and their families. With respect to the distribution of cost across different providers, 37% relates to care provided by physiotherapists and allied specialists, 31% is incurred in the hospital sector, 14% relates to primary care, 7% to medication, 6% to community care and 5% to radiology and imaging used for investigation purposes. However, the direct cost of back pain is insignificant compared to the cost of informal care and the production losses related to it, which total pound10668 million. Overall, back pain is one of the most costly conditions for which an economic analysis has been carried out in the UK and this is in line with findings in other countries. Further research is needed to establish the cost-effectiveness of alternative back pain treatments, so as to minimise cost and maximise the health benefit from the resources used in this area.

              A Comparison of Percutaneous Endoscopic Lumbar Discectomy and Open Lumbar Microdiscectomy for Lumbar Disc Herniation in the Korean: A Meta-Analysis

              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.
